SIIBJECT: November/December, 2000 Split Sampling Event at IUC White Mesa Uranium
Mill: Review of DEQ Groundwater Quality Data and Staff Findings.
Executive Summary
Twenty-one monitoring wells were sampled by both DRC and IUC during the November, 2000
split sampling event. Several known contaminants from uranium processing were identified by
DRC staff and examined herein. Ground Water Quality Standards (GWQS) were determined by
the staff for most of the contaminants examined. Comparison of the DRC and IUC split
sampling results were generally favorable for nitrate + nitrite (as N) [hereafter nitrate] and most
of the VOC contaminants. Poor comparability in the two (2) sets of data was apparent in the
remaining metals and radrologic parameters. For these contaminants, DRC staff relied mostly on
results provided by the State Health Laboratory (SHL).
The nitrate (N) GWQS, l0 mg/I, was exceeded by only one (l) well during the November, 2000
sampling event (TW4-2). From this well, an apparent north-south concentration ridge was
observed along the eastern margin of the facility, where it appears that oxidizing conditions exist.
A somewhat elevated nitrate concentration in one well northeast of the facility may also indicate
oxidizing conditions exist at that locale (MW-19). More than one (l) man-made source of nitrate
contamination exists at the IUC facility. Low nitrate levels seen downgradient of the tailings
cells may be explained by either a low initial nitrate concentration at the contaminant sources, or
by reducing groundwater conditions at the facility. In order to better understand the source(s) of
the nitrate contamination, DRC staff recommend that continued nitrate (N) sampling and
analysis be conducted of all existing and new monitoring wells at the facility.
Manganese concentrations were found to exceed the State GWQS, 800 ug/I, in five (5) wells at
the site. Two (2) of these were found "downgradient" of the tailings cells, while three (3) others
among the chloroform investigation wells. An inverse relationship was observed between nitrate
and manganese concentrations in the aquifer, suggesting that oxidizing conditions occur where
Memorandum
January l0,2OO3
Page 2
nitrate is elevated and manganese is not. High manganese concentrations, favored by reducing
groundwater conditions, were foygd in wells located "downgradient" of the tailings cells wells.
Low manganese concentrations in some areas may be explained by recharge of well oxygenated
groundwater from the nearby, unlined wildlife ponds. Based on existing IUC wastewater quality
data it is clear that the tailings cells are a significant potential source of manganese groundwater
contamination at the site. To better characteize and monitor local groundwater manganese
concentrations, additional monitoring wells may be needed west of Cells 1, 2, and 3; north of
Cell l, and east of Cells 1, and 3.
Sulfate concentrations in the local aquifer are highly variable. Both natural and potential man-
made sources of sulfate contamination exist in the uppermost aquifer near the IUC facility.
Tailings cell wastewater at the facility is a significant potential source of sulfate contamination
observed. DRC staff recommend additional studies be conducted to better delineate the origin of
the sulfate contamination, including sampling and analysis of: 1) dissolved sulfate content in
existing IUC monitoring wells, 2) dissolved sulfate levels in new monitoring wells to installed
for additional manganese characteization, and 3) dissolved sulfate concentrations in surface
water quality found in the northern wildlife ponds found near well MW-19, and 4) soil / rock
sampling and analysis of gypsum mineral content in vadose zone and aquifer materials at several
locations at the IUC facility, including areas near the northern wildlife ponds and well MW-19.
Uranium and gross alpha concentrations appear to be correlated at the site. Three (3)
"downgradient" wells located South and Southwest of Cell 4A exceeded the uranium GWQS, 30
ugil. One (1) well, MW-14, exceeded the EPA Title I uranium groundwater standard of 44 ryil
(40 CFR 192.04, Table 1). Six (6) wells at the facility exceeded the l5 pCi/l gross alpha GWQS.
Chloroform concentrations exceeded the State ad hoc GWQS, 80 ug/I, in seven wells at the
facility. All but one of these wells is a part of the ongoing chloroform investigation. An
apparent correlation may exist between nitrate and chloroform at the eastern margin of the site.
Trace quantity of chloroform in well MW-17 suggests the plume may have migrated southwest
away from the well MW-4 area.
Dichloromethane, a degradation product of chloroforrn, was found in one (1) of the chloroform
investigation wells at the facility at a concentration equal to the GWQS,5 ugll.
Carbon tetrachloride, a common co-contaminant in virgin chloroform product, was found in trace
quantities in two (2) of the chloroform investigation wells.
Tetrahydrofuran (TIIF) has been found in the same three (3) wells during two (2) consecutive
split sampling events at the facility, May, 1999 and November, 2000. DRC research indicates
that TFIF has unique chemical properties that allow formation of organo-metallic complexes.
Consequently, the potential exists that TFIF has been used in uranium/vanadium processing at the
IUC site. A low soil/water K6 is also apparent for TFIF at this site, suggesting it would be very
mobile in local groundwater. Confirmation of the presence of TFIF in the local groundwater is
important in that it may render a significant change in DRC interpretation of local groundwater
flow directions.

January 10,2003

Sulfur dioxide was also detected in the DRC results from one (l) well at the facility. This
volatile inorganic compound may be a product of either sulfuric acid digestion or combustion of
fossil fuels at the site.
Additional groundwater sampling and analysis is recommended for all the parameters and
monitoring wells considered in this report. Careful and continued measurement of local
groundwater head and flow directions is also critical. Groundwater redox measurements need to
be made to better understand the oxidation / reduction potential of the aquifer. All of this
monitoring must include the new IUC monitoring wells installed in July, 2002. Frnal
conclusions regarding the occurrence and distribution of all the above contaminants, their
source(s) and environmental fate may be possible after collection of this upcoming groundwater
quality and head data.
Introduction
The purpose of this memorandum is to document staff findings regarding groundwater quality
samples collected by DEQ during the November / December, 2000 split sampling event at the
IUC White Mesa uranium mill near Blanding. During this sampling event 21 wells were
sampled at the facility, including: MW-l thru MW-5, MW-l1, MW-12, MW-14, MW-15, MW-
17 thru MW-19, and chloroform investigation wells TW4-1 thru TW4-9. DEQ staff from both
the DRC (Loren Morton) and DWQ (Richard Denton) participated with IUC personnel in the
collection of these samples.
The DEQ split groundwater samples were delivered to the State Health Laboratory (SHL) for
analysis for several groups of inorganic parameters, including: general chemistry analytes,
nutrients, heavy metals, and radiologics. Results from these analyses are summarized in
Attachment l, below. By and large these are the same inorganic parameters examined during the
May,1999 DRC split sampling event. From experience at other uranium mill sites, several
contaminants are known to be common to uranium processing, including, but not limited to:
uranium-23S, manganese, molybdenum, nitrate + nitrite (as N), ammonia (as N), sulfate, and
vanadium, among others. Three of these contaminants, molybdenum, arrunonia, and vanadium,
had no exceedances of the respective State Ground Water Quality Standards (GWQS) from the
November,2000 sampling event; and therefore were not examined in this evaluation.
The split groundwater samples were also tested for volatile organic compounds (VOCs), and the
results thereof are found in Attachment 2, below. The majority of the VOCs tested were found
to be below their respective minimum reporting limit (MRL). However, several contaminants
were found at detectable concentrations; particularly chloroform, dichloromethane, carbon
tetrachloride, tetrahydrofuran, and sulfur dioxide. Two VOC compounds are known degradation
products of chloroform, dichloromethane, and chloromethane, however only dichloromethane
was found with detectable concentrations. Another VOC is commonly known to be coincident
in virgin chloroform product, carbon tetrachloride, and was found in detectable amounts in the
November, 2000 split sampling event. One other compound, 1,1-dichloroethane, was included
in this list based on its occurrence in the November,200l split sample results that will be
discussed later. Two other compounds were detected in the SHL samples only, including
tetrahydrofuran and sulfur dioxide.

Applicable GWOS
DRC staff determined applicable Ground Water Quality Standards (GWQS) for each
contaminant after review of several relevant sources, including:
Page 4
l.Regulatory Standards - adopted in the Ground Water Quality Protection (GWQP)
Regulations [UAC R3l7-6-2, Table 1], including: nitrate + nitrite (as N), arsenic,
barium, cadmium, chromium, copper, lead, mercury, selenium, silver, zinc, and carbon
tetrachloride.
EPA Drinking Water MCLsI - including enforceable Maximum Concentrations Limits
(MCL) adopted by the EPA drinking water program for the protection of human health.
These contaminants included: antimony, beryllium, thallium, uranium, chloroform, and
dichloromethane. For chloroform, the EPA MCL, 80 ug/I, is based on the total
concentration for five (5) trihalomethane compounds, including: bromodichloromethane,
bromoform, chloroform, dibromochloromethane, and dibromochloromethane.
EPA Drinking Water Lifetime Health Advisories (LHA)I - including concentrations
recommended by the EPA drinking water program for the protection of human health.
These compounds included: ammonia (as N), molybdenum, nickel, and chloromethane.
Enforceable GWQS From Other Statesl - including maximum groundwater contaminant
concentrations determined by other State governments as necessary for the protection of
human health. In the case of tetrahydrofuran a GWQS of 50 ug/l from the State of
Wisconsin was utilized by DRC staff (see Attachment 3, Table l, p. 327). This
concentration value is very similar to an ad-hoc drinking water lifetime health advisory
calculatedforthiscompoundbyEPA,Region 8,47 ugfl (seeAttachment4, page2).
Ad-hoc Determined GWOSl - for two (2) other contaminants DRC staff relied on
assistance from staff of the EPA Region 8 drinking water program to determine relevant
human health criteria for manganese and vanadium.
Staff Findings: Groundwater Ouality Data
After determining the applicable GWQS for the contaminants of interest, DRC staff then
completed a comparison of the reported data. Results of this comparison are summarized below.
Inorsanic Chemistry Findinss - 15 different wells at the facility exceeded one or more GWQS
during the November, 2000 split sampling event. Comparisons are also made with split sample
results provided by IUC, as follows:
1. Nitrate + Nitrite (as N) - comparison of the DRC and IUC results was a bit less than perfect.
Of the 21 wells analyzed for this parameter, three (3) of the IUC results provided
' The Utah GWQP Rules allow the Executive Secretary to establish ad-hoc GWQS for contaminants not specifically
listed in the regulations. Under these rules, the Executive Secretary rely on other sources of relevant human health
based information to determine Ad-hoc GWQS, including EPA drinking water MCL goals, health advisories, risk
based concentrations, or standards adopted by other regulatory agencies.

concentrations that were more than 20Vo different than the DRC values (MW-3, MW-5, MW-
12, see Attachment 5, spreadsheet Split00-1 1.xls, tabsheet NO3). In all three of these cases,
the IUC results were lower. Consequently, DRC staff relied on the SHL results for spatial
analysis and evaluation.
Of the SHL results, only 1 well exceeded the 10 mg/l GWQS, chloroform investigation well
TW4-2 (10.1 mg/l). However, elevated concentrations were also seen in two (2) other
nearby wells, including: MW-4 (9.52 mgll), and TW4-l (7 .43 mg/l). These three wells form
an apparent North-South concentration ridge along the East side of the IUC facility, see
Attachment 5 below (DRC map NO311-00_2b.sfl. A similar nitrate + nitrite (hereafter
"nitrate") concentration ridge exists between these three wells for chloroform, see discussion
below.
Elevated nitrate concentrations were also observed in an apparently upgradient well, MW-19
(2.02 mgll). No apparent source of for this nitrate is currently known. However, the
presence of nitrate in well MW-19 suggests oxidizing conditions exist in the aquifer at this
location (see Freeze & Cherry, pp. 117-118 and 413-415). Several sources forthis oxygen
content are apparent, the most likely being infiltration from the northern-most wildlife pond
which is an unlined impoundment supplied with a constant source of water from Recapture
Reservoir (see Attachment 5, map NO311-00_2.sO. In contrast, the undetectable nitrate
concentrations (< 0.1 mg/l) seen in upgradient wells MW-1 and MW-18, may indicate that
reducing aquifer conditions exist at these two locations.
Previous IUC reports have ascribed the presence of elevated nitrate in the chloroform
investigation wells to the co-disposal of the chloroform solvent with septic wastewater in the
on-site leachfields used prior to NRC approval of tailings Cell I (lll9l0l ruC/HGC Report,
p. l9). Occurrence of these two (2) contaminants together is consistent with other research
that indicates chloroform is degraded under reducing groundwater conditions, and not
oxidizing conditions (Pankow and Cherry, p. 80).
Nitrate found in the chloroform wells may also be explained by other man-made sources of
nitrogen at the IUC facility. One possible nitrogen source may be the high concentrations of
ammonia (as N) seen in the tailings wastewater which available IUC water quality data
indicates ranges from 1,761 to LL,432 mg/I, with an average concentration of 5,359 mgil (see
Attachment 10, below). However, at the low pH conditions found in the tailings wastewater
(about 1.0, see Attachment 10, below), ammonia in the tailings effluent would occur as
ammonium cation (NH4), and would be retarded during transport thru the underlying vadose
zone and aquifer (see Hem, p. 124 and Nebergall, et.al., p. 616). However, nitrate (N) has
been measured directly in one sample of the tailings wastewater at a concentration of 24 mgll
which is above the 10 mg/l GWQS (see Attachment 10, below). Consequently, the tailings
wastewater is a potential nitrate (N) source at the facility. For this reason and others,
additional monitoring wells were installed near Tailings Cell 2 in July, 2002.
It is also important to note the low nitrate concentrations seen downgradient of the tailings
cells in wells MW-3, MW-5, MW-l1, MW-12, MW-14, MW-15, and MW-17. Nitrate
concentrations at these locations were all below 0.23 mgfl, which is about l-order lower than
the concentration seen in upgradient well MW-19 (see Attachment 5, map NO3ll-00_2.srf).
These low downgradient concentrations could be interpreted as evidence that the tailings
cells have not discharged nitrogen contamination to the local groundwater. However, they
Memorandum
January 10, 2003
Page 6
could also be explained by: l) the low source term concentration, about 24 m{1, found in
the tailings effluent (see discussion above), or 2) low groundwater concentrations caused by a
reducing groundwater environment that would promote denitrification of nitrate; thereby
converting it to nitrogen gas (Freeze and Cherry, p. 118). The latter explanation is plausible,
in that reducing groundwater conditions are apparent in two (2) downgradient wells, MW-3
and MW-14 (see discussion on manganese below).
After review of the above observations, DRC staff recommend that nitrate (N) sampling and
analysis be continued from all monitoring wells at the IUC facility, and that additional
groundwater head and contaminant data be collected to improve our understanding of nitrate
contaminant sources and fate. It is hoped that the new IUC monitoring wells added in July,
2002 will contribute greatly to this understanding.
2. Manganese - comparison of the DRC and IUC split sampling results is less than satisfactory,
in that three (3) IUC samples were lost, reportedly due to freezing and breakage during
transit to their laboratory (9130102 email correspondence, Harold Roberts). Also, 15 other
IUC samples produced manganese results that were more than 207o different than the SHL
data; in some cases as much as 1987o lower and a 1957o higher (see AttachmentT,
spreadsheet SplitOO-11.x1s, tabsheet Mn). Review of the current SHL Certificate for IUC's
laboratory, Energy Laboratories Incorporated (ELI), shows that although ELI was certified to
analyze for several different metals via EPA Method 200.7 or 200.8, it was not certified to
analyze for manganese (see Attachment 8, below). Consequently, DRC staff relied on the
SHL results for manganese in its evaluation.
From the SHL results, five (5) wells exceeded the 800 ug/l GWQS, including: MW-3 (3,470
ug/l), MW-14 (2,060 ugil), TW4-5 (1,050 ug/l), TW4-6 (2,800 ug/l), and TW4-9 (1,330
ug/l), see Attachment 1. Of these wells, MW-3 and MW-l 4 appear to be located
hydraulically downgradient of the tailings cells. In particular, well MW-3 represents the
highest manganese concentration seen at the facility (compare Attachments 6 and 7, below).
Upgradient of the IUC facility the manganese concentrations are much lower, ranging from
16.9 to 233 ugll (see Attachment 7, DRC map Mnl l-00.srl). Comparison of the highest
upgradient location (MW-1) with the highest downgradient well (NfW-3) suggests a 15-fold
manganese increase exists across the site in a north to south direction.
The second highest manganese concentration at the facility, 2,800 ug/I, was found in
chloroform well TW4-6, which appears to be located beyond the southern boundary of the
nitrate plume (see Attachments 5 [map NO311-00_2c.srfl, and'l [map Mnll-00b.srfl,
below).
It would be desirable to compare these recent manganese concentrations with historic
groundwater quality information collected at the facility. However, review of four (4)
different IUC reports shows no manganese groundwater quality data are available for the
shallow aquifer at White Mesa (see 1/93 Umetco Minerals Corporation and Peel
Environmental Services Report [Appendix D],2193 Peel Environmental Report [Appendix
D),7194 Titan Environmental Report [Appendix B], and the9194 Titan Environmental
Report [Appendix A]). Consequently, the analysis here will have to focus on a spatial
evaluation of data recently collected.
One of the most salient observations suggests that the lowest manganese groundwater
concentrations found during the November, 2000 event were in wells where the nitrate
Memorandum
January 10, 2003
PageT
concentrations were highest at the facility. For example, compare the nitrate and manganese
concentrations in chloroform wells TW4-2,\/frr,1-4, and TW4-1, where manganese ranged
from 12.2 to 47.5 ug/I, and nitrate ranged from7.43 to 10.1 mg/l (see Attachments 1, 6, andT
IDRC map Mnl l-00b.srf,l).
This inverse concentration relationship may be explained by the fact that manganese is a
redox sensitive contaminant that is only soluble under reducing conditions (Hem, p. 87). In
contrast, nitrate (NO:) is the most stable nitrogen species under oxidizing groundwater
conditions (Deutsch, pp. 154-155). Oxidizing conditions force manganese to bind to the
aquifer matrix as an oxyhydroxide mineral (ibid.). Only when oxidizing aquifer conditions
reveft to a reducing environment will manganese become soluble and occur in significant
groundwater concentrations (ibid.). As a result, the low manganese and high nitrate
conditions found in the center of the current chloroform investigation near MW-4 suggest
that oxidizing conditions prevail in the aquifer there.
At other IUC locations a contrasting relationship exists where high manganese and low
nitrate concentrations are found in the same well. Examples of this are found downgradient
of the tailings cells in wells MW-3 and MW-14, and at the southern margin of the nitrate
plume in chloroform well TW4-6 (see DRC maps NO311-00b.srf and Mn1 1-00b.srf in
Attachments 5 and 7, respectively). This relationship may suggest that reducing groundwater
conditions are present at these aquifer locations.
Relatively low manganese conditions were also seen downgradient of the tailings cells in
well MW-17 (381 ugil), that may indicate that oxidizing conditions exist at this location (see
Attachment 7 below). Other evidence supports this interpretation for well MW-17,
including: 1) the proximity of the unlined southern wildlife ponds, located about 1,300 feet
northeast of this well that could contribute oxygenated recharge to the aquifer [ibid.], and2)
the trace quantity of chloroform (3.4 ug/l) detected in this well during the November, 2000
sampling event that might not be present if reducing conditions existed there (see Attachment
13, map CFll-00.srf, below).
Much of the above discussion assumes that the source of the manganese in the shallow
groundwater is solely from natural oxyhydroxide minerals bound to the aquifer matrix.
However, this assumption may not be valid. High concentrations of dissolved manganese
have been found in the IUC tailings solutions. Four (4) historic IUC water quality samples,
collected prior to 1988, have shown dissolved manganese to range between 80 to 222 mgll
(80,000 - 222,000 ug/l) with an average of 142,500 ug/l in the tailings effluent (see
Attachment 9, below). These same samples were also found to be very acidic, with pH
ranging between 0.7 and 1.8 (ibid.). These IUC wastewater characteristics are consistent
with research by the USGS and others which suggests that manganese cannot be maintained
in solution at such high concentrations unless the wastewater exhibits both reducing and low
pH properties (Hem, p. 87). Other IUC information shows manganese dioxide (MnO2) was
commonly added to the ore leach tanks, presumably as an oxidizingagent (May, 1999 ruC
Report, Figure B-2).
As a result, it is possible that the elevated manganese concentrations seen downgradient of
the tailings pond are a product of: 1) natural manganese released from the aquifer matrix due
to natural or man-made reducing groundwater conditions, or 2) the adverse effects of
groundwater pollution from a highly reducing and manganese charged tailings effluent.
Memorandum
January 10, 2003
Page 8
Based on these findings, the staff recommend that: 1) groundwater monitoring for
manganese continue at the facility, 2) groundwater redox measurements need to be made in
the field to better assess the oxidation / reduction conditions of the aquifer, 3) any significant
increase in groundwater manganese concentrations in the future should be cause for concern
and reason for further investigation, and 4) due to a current lack of groundwater monitoring
wells near a potential manganese contaminant source, additional wells need to be installed
along the west side of Cells 1, 2, and 3 (apparently downgradient); across the north side of
Cell I (apparently up and cross-gradient); and along the east side of Cell l, and Cell 3 (up
and cross-gradient).
3. Sulfate - comparison of the split sampling data shows the results were less than satisfactory,
in that two (2) of the IUC samples (MW-15 and TW4-4) were lost due to freezing and
breakage during transit to the laboratory (9130102 email from Harold Roberts). In addition,
seven (7) other IUC samples varied widely compared with the corresponding SHL results
(MW-l, MW-4, MW-5, MW-12, MW-14, TW4-3, and TW4-6, see Attachment 9, below). In
some cases the IUC data were as much as 38Vo lower and 98 7o higher (RPD) than the DRC
data. Review of the current SHL Certificate for the IUC laboratory, ELI, shows that sulfate
analysis has been certified by Standard Method 4500-SO42-E, see Attachment 8, below.
However, ELI reported that sulfate was analyzed by EPA Method200.7 (see ELI lab sheets
in IUC data submittals dated 916102 and 1012610l). Review of EPA Method 200.7 shows it is
a technique for determination of metals and trace elements by induced coupled plasma-
atomic emission spectrometry (ICP-AES), and does NOT detect sulfate (EPA, June, 1999,
method 200.7). Consequently, DRC staff relied on the SHL sulfate results in its evaluation.
No GWQS is currently available for sulfate. Consequently, no comparisons of the SHL
sulfate data were made in this regard. Instead, DRC staff examined spatial variations of
sulfate in the shallow aquifer by preparing an isoconcentration map in Attachment 9, below.
From this map, it appears that the lowest concentration,209 mg/I, is found in "upgradient"
well MW-l. Whereas, the highest concentration, 3,360 mg/I, was found in "downgradient"
well MW-3 (see Attachment 9 map SO4l1-00.srf, below). An obvious concentration "low"
was also found on the south margin of Cell 3 in well MW-l | (933 mg/l). Well MW-19 also
appeared as an isolated concentration "high" with unexplained levels at 2,293 mg/l sulfate.
On a smaller scale, the IUC sulfate concentration field exhibits a large degree of spatial
variability, particularly near the chloroform investigation wells. The second highest sulfate
concentration at the site was found in chloroform well MW-4 (2,750 mg/l), which appears to
be part of an isolated sulfate high near MW-4, TW4-7 (2,512 mg/l), and TW4-l (2,416 m{1,
see Attachment 9, map SO411-00b.srfl). A short distance to the south, about 400 feet, the
sulfate concentration drops sharply by more than 3-fold to774 mg/l in well TW4-4. Farther
to the south the trend reverses itself and rises to 2,501mg/l in well TW4-6; an increase of
more than 3007o which is almost comparable to the values observed near well MW-4.
Sources of the sulfate may be both natural and man-made. Natural sulfate type groundwater
has been described in the Dakota Sandstone / Burro Canyon aquifer in the Blanding area (see
Avery, pp.42 and 5l). In one well near Blanding, the groundwater sulfate content was
attributed to gypsum (ibid., p. 51). In contrast, bicarbonate dominant groundwater quality
has also been found in this same aquifer elsewhere in San Juan County (ibid.). A significant
man-made source of sulfate is also present at the IUC facility. Historic IUC tailings
Memorandum
January 10,2003
Page 9
wastewater quality data from five (5) different samples indicates that the average sulfate
content of the tailings cells effluent is over 104,000 mg/l (see Attachment 10, below). As a
result, the tailings disposal cells constitute a significant potential source of the sulfate
contamination observed in the uppermost aquifer at the site.
Because more than one (1) source of sulfate contamination is apparent, it will be important to
complete additional studies to further investigate the source of the groundwater
contamination and explain the wide spatial variability observed at the IUC site. DRC staff
recommends that additional studies be conducted, as follows: 1) additional sampling and
analysis be conducted of the existing wells, 2) sulfate sampling and analysis be conducted of
the new tailings cells wells recommended above for manganese characterization, 3) surface
water quality sulfate sampling and analysis be conducted from the northern wildlife ponds to
better characteize any sulfate charged infiltration water that may explain the elevated sulfate
concentrations in IUC well MW-19, and 4) soil / rock sampling and analysis of gypsum
minerals to investigate possible vadose zone or aquifer sources of sulfate at the IUC site.
Emphasis should be given to soils and aquifer matrix materials around the northern wildlife
ponds near well MW-19.
4. Uranium-238 - for several reasons, a poor comparison is apparent between the DRC and
IUC split sampling data for uranium-238 (hereafter uranium). Three (3) samples were lost
by IUC during transit to their laboratory, TW4-1, TW4-4, and TW4-6 (see Attachment 11,
spreadsheet SplitO0-11.xls, tabsheet U). More troubling is that only one (1) of the remaining
uranium samples met the 20VoRPD criteria, MW-18. For the other 17 samples analyzed the
differences between the DRC and IUC samples were greater than 20%o (RPD), ranging
between 1497o lower and 447o higher than the SHL data (see Attachment I l, spreadsheet
Split00-11.x1s, tabsheet U). The SHL results were produced with EPA Method 200.8 (ICP-
MS, personal communication, Mr. Ed Sanders, Sfil-). According to the ELI laboratory
reports, IUC also used this same analytical technique (9/6102IUC data submittal, ELI data
sets 30066R, 30070R, 30072R, and 30073R). Review of the SHL Certificate for ELI shows
that the laboratory is certified to use this method for other 11 metals, but not uranium. No
explanation is apparent for the inconsistency observed between these two (2) sets of
analytical data. Lacking an explanation for the discrepancy, DRC staff chose to rely on the
SHL data in its evaluation, described below.
Use of the SHL data shows that three (3) wells at the facility exceeded the 30 ug/l GWQS,
including: MW-3 (31.3 ug/l), MW-14 (58.6 ugil), and MW-15 (38.1 ug/I, see Attachment l).
The IUC results for these three (3) wells produced higher concentrations (see Attachment 11,
spreadsheet Split0O-11.xIs, tabsheet U). Consequently, DRC staff are confident that the
GWQS was exceeded at these wells. However, if the IUC data were to be used, three (3)
additional wells would appear to have exceeded the GWQS, including: MW-4, MW-17, and
MW-18 (ibid.).
The SHL data also show that one (1) well, MW-14, exceeds the EPA Title I uranium
groundwater protection standard of 44 ugll, established in 40 CFR 192.04, Table 1 However,
this standard does not apply to Title II uranium mill facilities, and no uranium groundwater
protection standard or compliance criteria has been established in the existing NRC Title II
license for the IUC White Mesa facility (see NRC License No. SUA-1358, Amendment22,
September 23,2002, Section 11.3.A, and September, L994 Titan Environmental Report, pp.
6-9 and Appendix B).
Memorandum
January 10, 2003

Review of the spatial distribution of the SHL shallow aquifer data shows that about aZ-fold
difference in uranium is apparent between the up and downgradient locations (see
Attachment 11, below). In the upgradient direction the highest uranium value was found in
well MW-18 at a concentration just below the GWQS at29.9 ug/I. The highest
downgradient concentration was found in well MW-14, where 58.6 ug/l of Uranium-238 was
detected. This contrast in spatial concentrations appears to be significantly lower than that
seen for manganese, as discussed above. Perhaps some of this contrast is due to natural
variation of uranium concentrations in the aquifer. However, before this conclusion is made
additional data need to be collected on groundwater flow directions, aquifer permeability,
and multiple events of uranium sampling and analysis conducted.
From the information available it is important to note that two (2) of the downgradient wells
with elevated uranium content also had elevated manganese concentrations (MW-3 and MW-
14, compare Attachments 7 and 11, below). The combination of elevated uranium and
manganese concentrations in these two (2) wells is perplexing. As discussed above, the
presence of dissolved manganese suggests that reducing conditions may be present in these
wells. However, this appears to be in conflict with basic geochemistry for uranium, with
suggests that uranium is generally insoluble under reducing conditions; precipitating as the
mineral uraninite (Deutsch, pp. l2I-122). The mobile and more soluble forms of uranium
are the generally the oxides, particularly uranyl (UOz) carbonate or sulfate complexes (ibid.,
and Hem, p. la8).
Consequently, the staff recommends that additional uranium sampling and analysis be
conducted from these wells and others at the facility. Hopefully, as additional groundwater
quality, flow direction information, and aquifer permeability data are available some
conclusion can be reached on this matter.
Radiologic Contaminant - one (l) radiologic contaminant from the November, 2000 sampling
event was considered, as follows below:
1. Gross Alpha - was the only radiological analysis conducted by SHL on the November, 2000
split samples. Review of the SHL and ELI results shows a poor comparison. As seen before,
IUC lost three (3) samples during transit to ELI, including TW4-1, TW4-4, and TW4-6
(9l30l02IUC email from Harold Roberts). Twelve (12) other ELI samples exhibited
concentrations that were more than207o different than the SHL results, ranging from about
59Vo higher to 709%o lower (see Attachment 12, spreadsheet SplitO0-11.xls, tabsheet Galpha).
Six (6) of the 21 wells sampled were found with gross alpha concentrations in excess of the
15 pCi/l GWQS, including (see Attachment 1): MW-3 (26 pCill), MW-4 (20.6 pCill), MW-
14 (26.9 pCi/l), MW-17 (25-8 pCill), MW-18 (16.6 pCi/l), and chloroform investigation well
Tw4-l (20.8 pCi/l).
Of these wells, MW-3, MW-14, and MW-17 form a concentration "high" located
downgradient of the tailings cells (see DRC maps in Attachments 6 and l2). Another gross
alpha high appears to be located among the chloroform investigation wells between MW-4
and TW4-l (see Attachment 12, DRC map Galphal l-00b.sfl. Another "high" appears in
well MW-18, which is "upgradient" from the tailings cells and without apparent explanation
at the present time.

From review of these DRC maps, the distribution of the gross alpha contamination closely
resembles that of Uranium-238. This is consistent with the fact that uranium is the most
likely naturally occurring alpha source in the White Mesa groundwater. For other DRC
observations on gross alpha spatial distribution, see the discussion on Uranium-238 above.
VOC Chemistrv Findines - 13 different wells at the IUC facility were found to contain one or
more VOC contaminants during the November, 2000 split sampling event (see Attachment2,
below). Several of these wells contained VOC concentrations that were above their respective
GWQS, as follows:
1. Chloroform - review of the SHL and ELI chloroform results shows a much better
comparability than any of the inorganic, metals, or radiologic contaminants listed above. No
IUC samples were lost during transit. Also, only two (2) ELI samples reported results that
exceeded the 20Vo RPD criteria, including MW-4, and TW4-1 (see Attachment 13,
spreadsheet Split00-11.xls, tabsheet CF). However, in both cases the ELI results were
conservatively higher than those reported by SHL. A third well, MW-18, appeared to exceed
tbe 20Vo criteria, but was ignored because the SHL result was an estimated value reported at
a concentration that was below the minimum reporting limit (MRL) of 1 ug/I. Three (3)
other ELI results were also reported with MRL values that exceeded the State GWQS, 80
ug/I, including wells MW-4, TW4-1, and TW4-2. However in all of these cases the detected
concentration was much higher, rendering this concern mute. Seven (7) ELI results were
found to be greater than the corresponding SHL values, but this was considered a
conservative error. Also, both the DRC and IUC trip blank concentrations were reported
below the MRL, 1 ugil; consequently all the chloroform results were considered valid and
reliable for this evaluation.
Seven (7) different IUC monitoring wells were found with chloroform concentrations in
excess of the GWQS (80 ug/l). All are a part of the on-going chloroform investigation, and
include: MW-4, TW4-1 thru TW4-3, TW4-5, TW4-7 and TW4-8. The highest
concentrations were found in wells MW-4 (5,030 ug/l) and TW4-2 (4,250 ug/l) located at the
center of the chloroform investigation (see Attachments 6 and 13 [DRC map CFl1-00b.srfl).
An apparent north-south concentration ridge may also exist betweenTW4-2, MW-4, and
TW4-1 (ibid.). The chloroform concentrations dramatically decrease across a short distance
east and west of this "ridge" in wells TW4-7 and TW4-8 (ibid.). A similar distribution
pattern exists in these same wells for nitrate (compare Attachment 13, map CF11-00b.srf
with Attachment 5, map NO3l1-00b.sfl. Likewise, a similar concentration "low" is found
on both maps in chloroform well TW4-9 (ibid.). This correlation supports a previous IUC
interpretation that the nitrate and chloroform contamination may be related (lll9l0l
IUC/HGC Report, p. 19). However, before final conclusions can be drawn regarding this
apparent relationship, additional groundwater quality data needs to be collected and analyzed.
from the new IUC monitoring wells installed in Jdy,2002.
Despite this apparent correlation, an exception exists in "upgradient" well MW-19, where an
elevated nitrate concentration was observed where no coffesponding chloroform was
detected (see Attachment 13, map CFI l-O0b.srf and Attachment 5, map NO311-00b.sfl.
Perhaps another explanation is apparent at this location.
Memorandum
January 10, 2003
Page 12
Small, but detectable chloroform concentrations were found in three (3) other wells at the
IUC site, including: MW-17 (3.4 ugll),TW4-4 (4.1 ug/l), and TW4-9 (36 ug/l). These three
reported concentrations appear to be reliable results, in that the DEQ trip blank shows no
detectable quantities of chloroform. This is further confirmed by the IUC quality assurance
(QA) samples collected during the sampling event (trip and equipment blanks), that also
show undetectable chloroform concentrations (10/26101 ruC transmittal, Energy
Laboratories Inc (ELI) results for QA samples MW-23, TW4-11, and TW4-12).
With regard to trace concentrations in well MW-17, it appears that the chloroform plume
may have traveled in a southwest direction from the well MW-4 complex (see Attachment
13, map CFl1-00.srf, below). This DRC result is considered reliable in that the IUC split
sample reported a similar concentration,3.T9 ug/l (see Attachment 13, DRC spreadsheet
Split00-l l.xls, tabsheet CF). Such contaminant travel appears consistent with local
groundwater flow directions (see Attachment 6).
Based on all the information above, DRC staff recommend that additional groundwater head
monitoring and chloroform sampling and analysis be conducted at all monitoring wells at the
IUC facility, including the new monitoring wells installed in July,2002. At a later date,
conclusions can be reached regarding the source(s) of chloroform and nitrate and their
apparent inter-relationship.
2. Dichloromethane - review of the DRC and IUC split sample results shows generally better
comparability than the non-organic compounds mentioned above. However, problems were
apparent with the IUC results in seven (7) wells due to reported MRL values that were not
less than the State GWQS, 5 ug/l; including wells MW-4,TW4-L,TW4-2, TW4-3, TW4-5,
TW4-1, and TW4-8; where the MRL ranged from 5 to 100 ug/l (see Attachment 14, below).
As a result, DRC staff decided to rely on the SHL values for this analysis. Trip blank results
also showed less than MRL values, consequently, the SHL values were considered reliable
for the November,2000 sampling event.
One (1) well, TW4-8, was found with a dichloromethane concentration slightly above the
GWQS, 5 ug/I. This well is located a short distance east of well MW-4, and is a part of the
on-going chloroform investigation. Dichloromethane is an anaerobic degradation product of
chloroform or trichloromethane (see Pankow and Cherry, p. 80). Perhaps reducing
conditions are present in well TW4-8, as evidenced by an undetectable nitrate concentration
(< 0.1 mg/l) and a slightly elevated manganese content (569 ugll, see Attachments 5, and7,
below). Due to this compound's occurrence in only one (1) well at the IUC facility, no
spatial analysis was done by DRC staff. Because this VOC is a chloroform degradation
product, the staff recommend that continued monitoring be conducted for this parameter and
a future evaluation be made.
3. Carbon Tetrachloride - review of the SHL and ELI results shows a slightly better comparison
than the non-organic compounds discussed above. None of the IUC samples were lost.
However, seven (7) ELI results were reported with a MRL that was not below the State
GWQS, 5 ug/I, including wells:MW-4, TW4-1, TW4-2, TW4-3, TW4-5, TW4-7, and TW4-
8; where the MRL ranged between 5 and 100 ug/l (see Attachment 15, below). For this
reason, DRC staff chose to rely on the SHL data for this evaluation. Review of the trip blank
Memorandum Page 13
January 10,2003
results indicate below MRL concentrations in both the SHL and ELI samples. Consequently,
the DRC data are considered valid and reliable.
None of the wells in question had carbon tetrachloride concentrations above the GWQS, 5
ug/l. However trace quantities were detected in wells TW4-1 (L.2 ug/l) and TW4-2 (3.1
ug/l). This is not surprising in that chloroform is a common co-contaminant in virgin
chloroform product (617l0l DRC Request for Additional Information, p. 5). Because this
compound was found in only two (2) wells at trace concentrations, no spatial analysis was
done by DRC staff. Because this compound is associated with virgin chloroform product, the
staff recommend that additional monitoring and study of this contaminant be made as a part
of the on-going investigation.
4. Tetrahydrofuran -no analysis of tetrahydrofuran (THB was reported in the ELI results for
volatile organic compounds. Consequently, the evaluation below focuses on the SHL results.
The DRC TI{F discussion is divided rnto 2 sections, as follows:
a. TFIF Properties. Uses and Provenance - Tfm or C+H3O is a colorless organic liquid that
is lighter than water, volatile, and is extremely soluble in water (Anderson, et. al., p. 98).
A partial summary of some of the chemical, physical, and environmental properties of
TFIF is provided in Table l, below.
One manufacturer touts TFIF as a versatile reagent due to a molecular structure that
allows the oxygen atom to carry two (2) unshared pairs of electrons, thus favoring
complexation and solvation of cations (Dupont, 2002). Another industry source
estimated the annual TFIF consumption as follows (Anderson, et. al., p. 98):
40Vo = resin and other solvent applications,
407o = applications as a chemical intermediate, and
207o = applications as a Grignard reaction solvent.
Grignard reactions were named after Victor Grignard of the University of Lyons who
received the l9l2 Nobel prize for his discovery of organic reagents that complex with
metals to form organo-metallic compounds, also known as Grignard reagents (Morrison
and Boyd, p. 91). The ability of TFIF to form organo-metallic compounds appears
consistent with the basic chemical processes used in the IUC solvent / extraction (S/X)
circuit to recover uranium and vanadium. In the IUC S/X circuit, kerosene appears to be
the most prevalent organic solvent (May, 1999 ruC Report, Figure B-2, process steps 59
- 65 [uranium], and 66 - 166 [vanadium]).
A TIIF manufacturer also reports that; "Tetrahydrofuran is miscible withwater and
common organic solvents. Thus, THF can be used alone or in mixtures with other less
active solvents to increase overall solvent power" (Dupont,2002). This statement may
suggest that TFIF could have been used as an additive to the kerosene solvent found in the
ruC S/X circuit. The dual solubility of TFIF organic solvents and in water may allow
more complete recovery of uranium and vanadium from the ruC SiX circuit.
It is also important to note that ammonia is commonly used to decompose the Grignard
reagents or organo-metallic compounds (Morrison and Boyd, p.92). Also noteworthy is
the fact that ammonia is used to recover uranium and vanadium from the final steps of the
Memorandum Page 14
January 10,2003
IUC S/X circuit (May, 1999IUC Report, Figure B-2, process steps 78 [uranium] and 108
[vanadium]). Hence, the use of THF appears to be generally compatible with several of
the basic processing steps in the IUC S/X circuit.

7) Range of soil/water Kd values in the EPA STF database based on 2 empirical tests on Captina silt loam
(0.3467 mUgm) and Mclaurin sandy loam (0.1202 ml/gm), with organic carbon contents of 1.497o and
O.66Vo, respectively.
8) EPA STF database Koc values determined by DRC staff in accordance with STF Kd and foc data, pursuant
to the following formula, Koc = Kd / foc. For the Captina silt loam, Kd = 0.3467 ml/gm and foc = 0.0149
gn/gm. For the Mclaurin sandy loam, Kd = 0.1202 mVgm and foc = 0.0066 grn/gm.
As a result of these considerations, it appears conceivable that TFIF could have been used
at the IUC facility as an additive in the S/X recovery circuit for either uranium or
vanadium. If true, the occurrence of TFIF in groundwater at the facility could be
explained by its use at the IUC operation.
b. TFIF Occurrence in Groundwater at White Mesa - as a groundwater contaminant, TIIF
has an extremely low soil/water partitioning coefficient (IQ), ranging from about 0.005 to
0.35 ml/gm (see Table 1, above). The upper part of this Ka range, values between 0.12 to
0.35 ml/gm, were based on sand and silt loam soils, respectively, with an organic carbon
fraction between 0.0066 to 0.0149 (ibid., footnote 8). At the IUC site, lower THF Kd
values are anticipated due to low organic carbon content expected in the sandstone
aquifer formations (Dakota Sandstone and Burro Canyon Formation). Accordingly, the
TIIF Kd at this site could easily be under 0.1 mligm.
In the May, 1999 split sampling event, TIIF was initially detected as a Tentatively
Identified Compound (TIC) in three (3) White Mesa monitoring wells, MW-I, MW-3,
and MW-12 (see Table 2, below). At the time of this analysis, no TIIF calibration curve
had been developed by SHL for the EPA 8260 method. Therefore, the May, 1999 TI{F
results were flagged as estimated and tentatively identified. Later, the SHL developed
the necessary calibration curves, and was able to quantify the TIIF concentrations for the
November, 2000 split sampling event.
During the second split sampling event in November, 2000, the same three (3)
monitoring wells were found to contain quantifiable TIIF concentrations (see Table 2,
below). In two (2) wells, the concentrations were found to exceed the 50 ugil GWQS
(MW-l and MW-3).
The presence of the highest November,2000 TFIF concentration in well MW-l is a
curious finding in that this well has historically been regarded as upgradient of the IUC
tailings cells and cross-gradient from the chloroform investigation near well MW-4 (see
Attachment 6, below). In the event that DRC staff are able to confirm that TIIF has been
used as an additive reagent in the ruC S/X circuit, well MW-1 will need to be re-
classified as a downgradient well, and additional wells will need to be located in closer
proximity to Cell 1 in order to adequately determine local groundwater head and flow
directions.
To resolve the above DRC observations and findings regarding TFIF, the staff
recommend that: l) Steps be taken to confirm the presence of TIIF at the facility; either
thru requests for additional information of IUC to confirm historic use of this compound,
or thru direct sampling and analysis of extraction solvents at the mill site, and/or
wastewaters held in the tailings cells; and 2) Study be made of the results of subsequent
split sampling (November, 2001 and September,2002) to confirm and further
Memorandum

substantiate the presence and distribution of TFIF in the local groundwater system.
Thereafter, decisions can be made regarding the need for additional groundwater
monitoring wells.

Tentatively identified compound or estimated concentration
5.I.l-Dichloroethane - this VOC compound was included in Attachment 2 because it was
found in a trace quantity in one (l) well in the next sampling event (November,2O0l).
However, during the November, 2000 split sampling event, no detectable quantities were
found in any of the IUC wells sampled (see Attachment 2). To date, an ad-hoc GWQS has
not been determined by DRC staff for this compound, in that no information has been found
regarding possible human health effects via drinking water.
Sulfur Dioxide - no analysis of sulfur dioxide was reported in the ELI results for volatile
organic compounds. Hence, no comparison of the split samples is possible for the
November, 2000 sampling event. However, this volatile inorganic compound was tentatively
identified in one (1) ruC well during the November, 2000 split sampling event, well TW4-9,
locatedabout850feetNorthof chloroformwellMW-4 (2lOttgll,seeAttachmentZ,below).
No ad-hoc GWQS has been established by DRC staff for this compound, owing to a lack of
EPA data regarding human health effects via drinking water.
However, it is important to note that sulfur dioxide can be a byproduct of using sulfuric acid
as an oxidizer, particularly when it is hot and concentrated (Nebergall, et. al., p. 58a). Large
amounts of sulfuric acid are used in the IUC milling process, typically about 392,000
pounds/day of mill operation (5199IIJC Report, p. A-8). Much of this is acid is heated with
steam upon introduction to the leach tanks (ibid., Figure B-2, process steps 20 and22).
Consequently, there is a potential that the sulfur dioxide found in well TW4-9 is a byproduct
of the milling process.
Another explanation may be that small amounts of sulfur dioxide can be generated by
combustion of sulfur compounds in coal, oil, or gasoline (Nebergall, et. al., pp.576 and 595).
Historically, IUC used coal fired boilers to heat water for the mill (personal communication,
Mr. Harold Roberts). Also, the groundwater sampling equipment at IUC relies in part on a
6.
Memorandum

Page 17
gasoline engine powered air compressor that activates the down-well sampling pump. The
likelihood that this engine is the source of the sulfur dioxide appears low, in that it is IUC's
standing practice to shut the engine off and use a bailer to sample the VOC parameters at the
end of each episode of well sampling.
Because this compound was only detected in one (1) well at the facility, DRC staff
recommend that additional sampling be conducted for sulfur dioxide before any conclusions
are drawn with regards to its origin.
Conclusions
Twenty-one monitoring wells were sampled by both IUC and DEQ during the November, 2000
split sampling event. Several contaminants known to be common byproducts of uranium
processing were examined by DRC staff. Other suspected uranium related contaminants were
also examined. State GWQS were determined for most of the contaminants examined.
Comparison of the DRC and IUC split sample results showed a varying degree of agreement.
No comparison could be made for the two (2) to three (3) samples lost by IUC, reportedly due to
freezing and sample breakage, for most of the contaminants analyzed. Reasonably good
agreement was seen between the two DRC and IUC analyzes for nitrate + nitrite (as N) and most
of the VOC contaminants. Iess than satisfactory comparison was apparent for most of the
metals and one (l) radiologic parameter examined. In these cases, DRC staff relied largely on
the SHL results to evaluate the November, 2000 split sampling data.
Nitrate + nitrite (as N) concentrations at the IUC site exceeded the State GWQS, 10 mg/I, at only
1 well, TW4-2, where an apparent north-south striking concentration ridge and zone of oxidized
groundwater may exist. More than one (l) man-made source of nitrate contamination exists at
the IUC facility. Trace nitrate concentrations observed in several downgradient wells may be
explained by either a low initial concentration at the contamination source, or by reducing
groundwater conditions that encourage denitrification and conversion of nitrate to nitrogen gas.
A somewhat elevated nitrate concentration observed in upgradient well MW-19 indicates that
oxidizing groundwater conditions exist there also. In an effort to understand the cause of the
nitrate contamination observed in local groundwater, DRC staff recommend that continued
nitrate sampling and analysis continue at all existing and new IUC monitoring wells.
Manganese in five (5) wells at White Mesa were found to exceed the State GWQS, 800 ugil.
Two (2) of these appear to be downgradient of the tailings cells (MW-3 and MW-14); while
three (3) others were located among the chloroform investigation wells (TW4-5, TW4-6, and
TW4-9). An inverse correlation was observed where the lowest manganese concentrations
occurred in wells where the highest nitrate concentrations were found. One explanation may be
the occurrence of oxidizing conditions in the aquifer where nitrate is present, combined with the
insoluble nature of manganese under such conditions. High manganese concentrations at
downgradient aquifer locations may also be explained by leakage from the tailings cells, which
are known to contain wastewater under strongly reducing conditions with high manganese
content. Due to a current lack of wells, additional monitoring wells are needed west of Cells l,
2, and 3; north of Cell 1, and east of Cells l, and 3. The low manganese concentration seen in
downgradient well MW-17 may be explained by recharge of oxygenated infiltration from the
unlined wildlife ponds located nearby.
Memorandum
January 10, 2003
Page 18
Sulfate groundwater concentrations were also variable at the IUC site. The lowest concentration
was found in upgradient well MW-l; while the highest was located in apparently downgradient
well MW-3. Other areas of localized concentration "lows" were observed in "downgradient"
well MW-l1, and chloroform well TW4-4. Areas of concentration "highs" were seen in
"upgradient" well MW-19 and chloroform well MW-4. Both natural and man-made sources of
sulfate contamination exist in the uppermost aquifer at the IUC facility. DRC staff recommend
that additional studies be conducted to better delineate the source of the sulfate contamination,
including new and continued groundwater monitoring, sulfate sampling of surface waters found
in the northern wildlife ponds, and gypsum mineral sampling and analysis of soils and rock
materials at the facility, with emphasis on the northern wildlife ponds, well MW-19, and other
areas of the site.
Uranium results from the SHL show groundwater at the IUC facility exceeded the State ad hoc
GWQS, 30 ug/I, in three (3) wells. All of these were located "downgradient" of the tailings
cells, in wells MW-3, MW-14, and MW-15. ruC results for uranium indicate that three
additional wells also exceeded the GWQS, including: chloroform well MW-4, downgradient
well MW-17, and upgradient well MW-18. The SHL data also show that one (l) well exceeds
the EPA Title I uranium standard for groundwater protection, 44 lugll (40 DFR 192.04, Table 1).
Due to a lack of federal requirement for Title II uranium facilities, the current NRC license for
the IUC site does not include any uranium groundwater protection standard or compliance
criteria.
Gross alpha results largely correlate with the uranium concentrations reported; suggesting that
uranium is likely the largest component of the gross alpha activity in the shallow aquifer at
White Mesa. The State GWQS, l5 pCi/I, was exceeded in six (6) of the wells at the IUC site,
including: "upgradient" well MW-18, "downgradient" wells MW-3, MW-14, and MW-17, and
chloroform investigation wells MW-4 and TW4-1.
Chloroform concentrations were found to exceed the State GWQS, 80 ug/I, in seven (7) wells at
the facility. In general the chloroform was constrained to the investigation wells installed near
well MW-4, with one exception, "downgradient" well MW-17 where atrace quantity of
chloroform was detected. Because well MW-17 is located south of Tailing Cell 4A., it may be
possible that the chloroform plume has traveled southwest from the well MW-4 area. Another
important distribution feature is an apparent north-south ridge of elevated chloroform
contamination is also apparent between wells TW4-2,NNV-4, and TW4-1. Dramatic decreases
in concentration were also seen in a very short distance east and west of this "ridge" in wells
TW4-7 and TW4-8. A similar pattern of nitrate distribution is seen in the chloroform
investigation wells, which may suggest that these two (2) contaminants are inter-related in some
manner. DRC staff recommend that additional groundwater head monitoring and chloroform
sampling and analysis be conducted in all wells at the facility in order to better resolve and
determine the source(s) of chloroform contamination.
Dichloromethane was found in only one (1) well at the IUC facility, TW4-8 at a concentration
that equaled the State GWQS, 5 ug/I. Because this compound is a degradation product of
chloroform, DRC staff recommend that additional sampling and analysis be conducted at all
wells at the facility to better determine the distribution, cause, and environmental fate of this
contaminant.

Carbon tetrachloride, a know co-contaminant with virgin chloroform product, was found in trace
quantities in two (2) chloroform wells, TW4-1 and TW4-2. DRC staff recommend that
continued monitoring be conducted at all wells at the facility to better resolve the sources and
fate of this compound.
Tetrahydrofuran (T[IF) was found in DRC results from the same three (3) wells at the IUC
facility during two (2) consecutive split sampling events; May, 1999 and November, 2000
("upgradient" well MW-1, and downgradient wells MW-3, and IvfW-12). DRC research
suggests that TIIF has unique properties in forming organo-metallic complexes. As a result, it is
possible that this compound has been used at the IUC facility in uranium/vanadium processing.
A low soil/water partitioning (IQ) coefficient, below 0.1 ml/gm, is also apparent for TIIF at the
White Mesa site, which would cause the compound to travel at the leading edge of a contaminant
plume. The presence of TF{F in "upgradient" well MW-l may require revision of current
understanding of local groundwater flow directions, and necessitate installation of additional
monitoring wells in closer proximity to Tailings Cell l. DRC staff recommend that additional
steps be taken to confirm the presence of TF{F in groundwater at the facility thru both review of
subsequent monitoring data and continued THF sampling and analysis.
Sulfur dioxide was found in the DRC results from one (l) well at the facility during the
November,z000 sampling event, TW4-9. DRC research shows that this volatile inorganic
compound may be a by-product of sulfuric acid digestion or the combustion of sulfur bearing
fossil fuels at the facility. DRC staff recommend that additional sampling and analysis of this
compound be conducted at the facility before any final conclusions are drawn regarding its
source and fate.

1) Blank = no GWQS exists, nor could an Ad-hoc GWQS be derived by DRC staff.
2) Values Without Footnotes = GWQS promulgated by rule in the Utah Ground Water Quality Protection (GWOP)
Regulations, UAC R317-6-2, Table 1.
3) Values With Footnotes = Ad-hoc GWQS, primarily derived from EPA drinking water Maximum Contaminant Levels
(MCLs) or Lifetime Health Advisories, as authorized by the GWQP Rules in UAC R317-6-2.2.

Comment: Ammonia (NH3) GWQS: EPA draft Lifetime Health Advisory = 30 mg/|, and is converted to Ammonia-nitrogen (NH3 as
N) as follows:
NH3 (as N) GWOS = NH3 GWQS * Atomic Weight of N / Atomic Weight of NH3
= 30 mg/l " 14.0067 I 114.0067 + 3 * 1.0079)l
= 30 mg/l" 14.0067 117.0304
= 24.67 mg/l, round to 25 mg/|.
Cell: C27
Comment: Antimony GWQS: 0.006 mg/lvalue is based on Ad-Hoc GWQS deruved from a linal EPA drinking water MCL (see EPA
"Drinking Water Standards and Health Advisories", Summer, 2000, EPA 822-8-00-01).
Celt: C30
Gomment: Beryllium GWQS: the 0.004 mg/lvalue is based on Ad-Hoc GWQS derived from a final EPA drinking water MCL (see
EPA "Drinking Water Standards and Health Advisories", Summer, 2000, EPA 822-8-00-01).
Cell: C38
Comment: Manganese (Mn) GWQS: is based on EPA DW dralt Health Advisary Reference Dose (RfD), RfD = 0.14 mg/kg/day lor
the consumption of food and water (see summary entitled "Drinking Water Regulations and Health Advisories", October,
1996, EPA Office of Water, EPA822-8-96-002, p. 8). For a 70-kg adult, the RfD can be expressed as: 0.14 mg/kg/day.
70 kg = 9.8 mg/day Mn (see '1211196 EPA lRlS database printout on Manganese, p. 4). Now to convert the RfD to a
health advisory, do as follows:
(RfD - 5 mg/day) I (3- 2literlday intake) = 0.8 mg/|, where:
5 mg/day = National Research Council's "estimated safe and adequate daily dietary intake" for manganese (ESADDI),
and
Factor ol3 = to protect infants
(see 1/3/00 EPA Region I letter from Bob Benson (toxicologist) to Loren Morton Utah DEQ/DRC, and 1211196 EPA lRlS
database printout on Manganese, pp. 3-5).
Note that this concentration, 0.8 mg/l, is GREATER than the EPA secondary DW MCL of 0.05 mg/|, which was set
primarily on the fact that manganese concentrations above this value tend to stain laundry (personal communication, Mr.
Bob Benson, EPA Region 8 DW toxicologist).
Previously the State's Ad Hoc GWQS for manganse was proposed at 0.04 mg/|, based on a former RfD value and
calculations by EPA Region 8 toxicologist, Bob Benson (personal communicalion,2llTlg5). However, the ingestion RfD
was revised in the EPA lRlS database on 1111195. Thus it was necessary to now update the State's Ad Hoc GWQS.
Cell: C40
Comment: Molybendum GWQS: the 0.04 mg/l value is based on Ad-Hoc GWQS derived from a final EPA drinking water Lifetime
Health Advisory (see EPA "Drinking Water Standards and Health Advisories", Summer, 2000, EPA 822-8-00-01).

Comment: Nickel GWQS: the 0.1 mg/lvalue is based on Ad-Hoc GWQS derived from a final EPA drinking water Lifetime Health

Cell: C46
Comment: Thallium GWQS: the 0.002 mg/l value is based on Ad-Hoc GWQS derived from a final EPA drinking water MCL (see

Cell: C47
Gomment: Vanadium GWQS: based on a Lifetime Health Advisory (LHA) calculated by Utah Division of Radiation Controlstaff,
with the assistance of Mr. Bob Benson, EPA Begion 8 Drinking Water Program Toxicologist. ln turn, this LHA was based
on a EPA drinking water reference dose (RfD) for vanadium pentoxide (V2O5). For additional details, see 7/18/96 Utah

Cell: C49
Comment: Uranium GWQS: the 0.03 mg/l value is based on Ad-Hoc GWQS deruved from a final EPA drinking water MCL for total
uranium (see see 1217100 Federal Register, p. 76750). The SHL analysis done by ICP-MS only detects Uranium-238.
Consequently, it under-estimates the total uranium concentration somewhat, in that Uranium-234 goes un-measured.

Subchapter I - General
NR 140.01 Purpose. The purpose of this chapter is to
establish groundwater quality standards for substances detected
in or having a reasonable probability of ent€ring the groundwa-
ter resources of the state; to specify scientifically valid proce-
dures for determining ifa numerical standard has been attained
or exceeded; to specify procedures for establishing points of
standards application, and for evaluating groundwater monitor-
ing data; to establish ranges of responses the departrnent may
require if a groundwater standard is attained or exceeded; and to
provide for exemptions for facilities, practices and activities
regulated by the department.
Hlstory: Cr. Register, Septembs, 1985, No.357, eff. l0-l-85.
NR 140.02 Regulatory framework. (1) This chapter
supplements the regulatory authority elsewhere in the statutes
and adminisrative rules. The department will continue to exer-
cise the powers and duties in those regulatory programs, consis-
tent with the enforcement standards and preventive action limits
for substances in groundwater utrder this chapter. This chapter
provides guidelines and procedures for the exercise of regula-
tory authority which is established elsewhere in the statutes and
administrative rules, and does not create independentregulatory
authority.
(2) The department may adopt regulations which establish
specific design and management criteria for regulated facilities
or activities, if the regulations will ensure that the regulated
facilities and activities will not cause the concentration of a sub-
stance in groundwater affected by the facilities or activities to
exceed the enforcement standards and preventive action limits
under this chapter at a point of standards application. The depart-
ment may adopt more stringent regulations under authority else-
where in the statutes based on the best currently available
technology for regulated activities and practices which ensure a
greater degree of groundwater protection or when necessary to
comply with state or federal laws.
(3) Preventive action limits serve to inform the deparfrnent
of potential groundwater contamination problems, establish the
level of groundwater contamination at which the department is
required to commence efforts to control the contamination and
provide a basis for design and management practice criteria in
adminisuative rules. Preventive action limits are applicable both
to conrolling new releases of contamination as well as to restor-
ing groundwater quality contaminated by past releases of con-
taminants. Although a preventive action limit is not intended to
always require remedial action, activities affecting groundwater
must be regulated to minimize the level of substances to the
extent technically and economically feasible, and to maintain
compliance with the preventive action limits unless compliance
with the preventive action limits is not technically and economi-
cally feasible.
(a) The department may take any actions within the context
of regulatory programs established in statutes or rules outside of
this chapter, if those actions are necessary to protect public
health and welfare or prevent a significant damaging effect on
groundwater or surface water quality for present or future con-
sumptive or nonconsumptive uses, whether or not an enforce-
ment standard and preventive action limit for a substance have
been adopted under this chapter. Nothing in this chapter autho-
rizes an impact on groundwater quality which would cause sur-
face water quality standards contained in chs. NR 102 to 105 to
be attained or exceeded.
History: Cr. Register, January, 1992, No. 433, eff. 2-l-92; reprinted to restore
drcpped copy, Register, March, 1992, No. 435.
NR 140.03 Applicability. This subchapterand subch. II
apply to all facilities, practices and activities which may affect
groundwater quality and which are regulated under chs. 85, 93,
94, 101, 145,281,283,287,289,291 and292, Stats., by the
department of agriculture, trade and consumer protection, the
department of commerce, the department of transportation, or
the departrnent ofnatural resources, as well as to facilities, prac-
tices and activities which may affect groundwater quality which
are regulated by other regulatory agencies. Health-related
enforcement standards adopted in s. NR 140.10 also apply to
bottled drinking water manufactued, bottled, sold or distributed
in this state as required by s. 97.34 (2) (b), Stats., and to deter-
mining eligibility for the well compensation program under s.
281.75, Stats. Subchapter Itr applies to all facilities, practices
and activities which may affect groundwater quality and which
are regulated by the department under ch. 281, 283,287,289,
291,292,295 or 299, Stats. This chapter does not apply to any
facilities, practices or activities on a prospecting site or a mining
site because those facilities, practices and activities are subject
to the groundwater quality requirements of chs. NR 13l, 132 and
182. The department may promulgate new rules or amend rules
governing facilities, practices or activities regulated under ch.
293, Stats., if the department determines that the amendment or
promulgation of rules is necessary to protect public health,
safety or welfare. The requirements of this chapter are in addi-
tion to the requirements of any other statutes and rules.
Note: The groundwater standards in this chapter do not replrce the muimum
contarninant levels applicable to public water systems contained in ch. NR 809.
Drinking warcr muimum contaminanr levels md health advisory levels my take
into account such factors as treatment costs and feasibility for public water systems.

ance with the rules promulgated under s. 160-21, Stats. No
response shall be required ifit is demonstrated to the satisfaction
of the appropriate regulatory agency that a scientifically valid
determination cannot be made that the preventive action limit or
enforcement standard for a substance in Table 1 or 2 has been
attained or exceeded based on consideration of sampling procel
dures or laboratory precision and accuracy, at a significance
level of 0.05.
(2) The regulatory agetrcy shall use one or more valid statis-
tical procedures to determine if a change in the concentration of
a substance has occurred' A significance level of0.05 shall be
used for all tests.
(3) In addition to sub. (2), the following applies when a pre-
ventive action limit or enforcement standard is equal to or less
than the limit of quantitation:
(a) If a substance is not detected in a sample, the regulatory
agency may not consider the preventive action limit or enforce-
ment standard to have been attained or exceeded.
(b) If the preventive action limit or enforcement standard is
less than the iimit of detection, and the concentration of a sub-
stance is reported between the limit of detection and the limit of
quantitation, the regulatory agency shall consider the preventive
action limit or enforcement standard to be attained or exceeded
only if:
1. The substance has been analytically confirmed tobe pres-
ent in the same sample using an equivalently sensitive analytical
method or the same analytical method, and
2. The substance has been statistically confirmed to be pres-
ent above the preventive action limit or enforcement standard,
determined by an appropriate statistical test with sufficient sam-
ples at a significance level of0.05.
(c) If the preventive action limit or enforcement standard is
between the limit of detection and the limit of quantitation, the
regulatory agency shall consider the preventive action fimit or
enforcement standard to be attained or exceeded if the con-
centration of a substance is reported at or above the limit of
quantitation.

NR 140.24 Responses when a preventive action
limit is attained or exceeded. (1) NonncanoN AND
AssESsMENr. If the concentration of a substance, including indi-
cator parameters, in groundwater attains or exceeds a preventive
action limit at a point of standards application as described in s.
NR 140.22 (2):
(a) The owner or operator of the facility, practice or activity
shall notify the department in writing when monitoring data is
submitted that a preventive action limit has been attained or
exceeded in accordance with any deadlines in applicable stat-
utes, rules, permits or plan approvals. Where no deadlines are
imposed, the owner or operator shall notify the departrnent as
soon as practical after the results are received. When the results
of any private well sampling attain or exceed a preventive action
limit, the owner or operator of the facility, practice or activity
shall notify the department within l0 days after the results are
received. The notification shall provide a preliminary analysis
of the cause and significance of the concentration.
Regisrcr, March, 2000, No. 53l
Note: Section 292.11 (2) (a), Stats., rcquires that the department be notifred
imediately of hazardous substance dischuges.
Note: See s. NR 1210.27.
(b) Upon receipt of the notice under par. (a), the department
shall evaluate the information and, if further information is
required to make the assessment under par. (c), direct the owner
or operator to prepare and submit a report by a specified dead-
line. The report shall assess the cause and significance of the
increased concentration based on a consideration of the factors
identified in par. (c) and shall propose a response to meet the
objectives of sub. (2).
(c) The department shall assess the cause and significance of
the concenEation of the substance in determining the appropri-
ate response to meet the objectives of sub. (2). In addition to all
other relevant information, the department shall consider the
information submitted under par. (b) and the following factors
where applicable:
1. Background water quality. a. The department shall
compare background water quality data and monitoring data
from wells downgradient of the facility, practice or activity to
determine if downgradient water quality is adversely affected.
If the background water quality at a facility, practice or activity
is not known or is inadequately defined, the department may,
require additional sampling of existing wells, or installation and
sampling of additional wells, or both.
b. Except for substances which are carcinogenic, terato-
genic or mutagenic in humans, before requiring a response at a
site where the background concentration of a substance is deter-
mined to be equal to or greater than the preventive action limit,
the department shall determine that the proposed remedial
action will protect or substantially improve groundwater quality
norwithstanding the background concentrations of naturally
occurring substances.
2. Reliability of sampling data. As part of its review of the
quality of the sampling data, the departrnent shall evaluate the
sampling.procedures, precision and accuracy of the analytical
test, size ofthe data set, and the quality control and quality assur-
ance procedures used. Ifthere is insufficientinformation to eval-
uate the reliability of the sampling data, the departrnent may
require additional samples or other changes in the monitoring
program at the facility, practice or activity.
3. Public health, welfare and environmental effects of the
substance. The department shall consider the public health, wel-
fare and environmental effects of the substance, including but
not limited to its mobility in the subsurface, environmental fate,
the risks considered when the standard was adopted and whetherit is carcinogenic, mutagenic, teratogenic or has interactive
effects with other substances.
4. Probability that apreventive action limit or an enforce-
ment standard may be attained or exceeded outside the design
management zone. In evaluating the probability that a preven-
tive action limit or an enforcement standard may be attained or
exceeded outside the design management zone, the department
shall consider, at aminimum, geologic conditions, groundwater
flow rate and direction, contaminant mobility in the subsurface
and environmental fate.
5. Performance of the facility, practice or activity. The
departrnent shall consider whether the facility, practice or activ-
ity is performing as designed in accordance with the design
requirements in s. NR 140.22(1).The department shall consider
the type, age and size ofthe facility, practice or activity; the type
ofdesign, ifapplicable; the operational history; and otherfactors
related to performance of the facility, practice or activity as
appropriate.
6. Location of the monitoring point. The department shall
consider the location of the monitoring point in relation to the
facility, practice or activity and the design management zone in
assessing the appropriate response.

monitoring to determine whether or not natural attenua-
tion is occurring in compliance with the response objec-
tives in s. NR 140.24 (2).
(5) No AcrroN REspoNSE cRrrERrA. For facilities, practices
and activities with a design management zone specified in s. NR
140.22 (3) Table 4, the department may determine that no
response is necessary and that an exemption under s. NR 140.28
is not required when either of the following conditions is met:
(a) The concentration of a substance within a design manage-
ment zone is detected above the preventive action limit, the
enforcement standard has not been attained or exceeded within
the design management zone, and the department determines
that there is no indication that the preventive action limit will be
attained or exceeded at any point outside the design manage-
ment zone, or

area. If other known or suspected sources are present in the
vicinity of a facility, practice or activity of concern, the depart-
ment shall evaluate the probability of contributions from other
sources of the substance. The department shall consider, at a
minimum, the number, size, type and age of nearby sources; the
groundwater flow patterns; and the substances involved.
8. Hydrogeologic conditions. The department shall con-
sider the geologic and groundwater conditions, including but not
limited to the nature, thickness and permeability of the uncon-
solidated materials; the nature and permeability of bedrock; the
depth to the water table; groundwater flow gradients, both verti-
cal and horizontal; the position ofthe facility, practice or activity
within the groundwater flow system; and the present and poten-
tial groundwater use in the vicinity of the facility, practice or
activity at which an exceedance occurs. If there is insufficient
hydrogeologic information, the department may require addi-
tional information.
9. Extent of groundwater contamination. The departrnent
shall consider the current and anticipated future extent of
groundwater contamination in 3 dimensions. If water supplies
are affected or threatened, the department shall evaluate the
existing effects and potential risks of the substance on the pota-
ble water suppfies. If the extent of contamination is not known,
the departrnent may require further documentation of the extent
of cbntamination.
10. Alternate responses. The departrnent shall evaluate
alternate responses, including consideration ofthe technical and
economic feasibility of alternate responses from Table 5 or 6 or
both, the practicality of stopping the further release of the sub-
stance and the risks and benefits of continued operation of the
facility, practice or activity and the ability of a response to meet
other applicable environmental protection laws.
(2) Rrsrousr oBJECTIvES. Based on its evaluation of the
reportrequired under sub, (l), and the assessment criteria of sub.
(1) (c), the department shall specify the responses to be imple-
mented by the owner or operator of the facility, practice or activ-
ity designed to the extent technically and economically feasible
to prevent any new releases of the substance from traveling
beyond the design management zone or other applicable points
of standards application described in s. NR 140.22 and restore
contaminated groundwater within a reasonable period of time,
considering the criteria speci{ied in s. NR 722.07. Both the
source control and the groundwater restoration components of
the response shall be designed and implemented to:
(a) Minimize the concenEation of the substance in ground-
water at the point of standards application where technically and
economically feasible;
(b) Regain and maintain compliance with the preventive
action limit. If the department determines that compliance with
the preventive action fimit is either not technically or economi-
cally feasible, the owner or operator shall achieve compliance
with the lowest possible concentration which is technically and
economically feasible; and
(c) Ensure that the enforcement standard is not attained or
exceeded at the point of standards application.

FARE CoNCERN. If nifates or any substance of welfare concern
only attains or exceeds an enforcement standard, the department
is not required to impose a prohibition or close a facility if it
determines that:
(a) The enforcement standard was attained or exceeded, in
whole or in part, because of high background concentrations of
the substance; and
concentration is not greater than the enforcement standard either
within or outside of the design management zone.
(6) PnorurmoN AND cLosuRE cRITERIA. The departnent
may not impose a prohibition on a practice or activity or require
closure of a facility which produces the substance unless the
department:
(a) Bases its decision upon reliable test data;
(b) Determines, to a reasonable certainty, by the greater
weight of the credible evidence, that no other remedial action
would prevent the violation of tJre enforcement standard at the
point of standards application;
(c) Establishes the basis for the boundary and duration of the
prohibition; and
(d) Ensures that any prohibition imposed shall be reasonably
related in time and scope to maintaining compliance with the
enforcement standard at the point of standards application.

rary exemption if the criteria in this subsection are complied
with. This exemption applies to the owner or operator of a facil-
ity, practice or activity that is undertaking a remedial action that:
includes the infiltration or injection of contaminated groundwa-
ter or remedial material, has been approved by the depaffment,
and will comply with the applicable response objectives under
s. NR 140.24 or 140.26 within a reasonable period of time. The
owner or operator of the facility, practice or activity may submit
a temporary exemption request to the department at the same
time or after the department has approved the remedial action.
(b) Exemption re que st. The owner or operator of the facility,
practice or activity shall submit a request for a temporary
exemption to the department. As part of the request, the appli-
cant shall indicate how the exemption prerequisites under par.
(c) and applicable remedial design, operational and monitoring
criteria under par. (d) will be met.
Note: For most rcmedial actions, a microcosm or treatability study, or other
bench scale or pilot scale study will be required by the depanment prior to consider-
ation of an exemption for the full-scale remedial action under this section. Ifapilot
scale study is deerEd necessary before an exenrption for a full-scale remedial
action can be graned, a separate temporary exemption issued under this section is
required beforc the pilot scale study can begin.
(c) Exemption prerequisites. As part of the temporary
exemption request, the owner or operator shall demonstrate to
the satisfaction of the departrnent that all of the following
requirements will be met:
1. The remedial action for restoring contaminated soil or
groundwater, and any infiltrated or injected contaminated water
and remedial material, shall achieve the applicable response
objectives required by s. NR 140.24 (2) or 744.26 (2) within a
reasonable period of time
2. T\e type, concenEation and volume of substances or
remedial material to be infiltrated or injected shall be minimized
to the extent that is necessary for restoratiou'of the contaminated
soil or groundwater and be approved by the department prior to
use.
3. Any infiltration or injection of contaminated water or
remedial material into soil or groundwater will not significantly
increase the threat to public health or welfare.
4. No uncontaminated or contaminated water, substance or
remedial material will be infiltrated or injected into an area
where a floating non-aqueous phase liquid is present in the con-
taminated soil or groundwater.
5. There will be no expansion of soil or groundwater con-
tamination, or migration of any infilnated or injected contami-
nated water or remedial mat€rial, beyond the edges of pre-
viously contaminated areas, except that infiltration or injection
into previously uncontaminated areas may be allowed if the
departrnent determines that expansion into adjacent previously
uncontaminated areas is necessary for the restoration of the con-
taminated soil or groundwater, and the requirements of subd. 1.
will be met.
6. All necessary federal, state and local licenses, permits
and other approvals are obtained and all applicable environmen-
tal protection requirements will be complied with.
Not€: The issuance of a wastewater discharge permit by the department is
required prior to the infiltation or injection of substances orremedial material into
unsatuated soil or groundwarct A wastewater discharge pemit establishes the
effluent or injection limits for substaces or remedial material which may be infil-
trated or injected into unsaturated soil or grcundwater. A temPorary exempdon

MEMORANDUM
DATE:August 24,1999
SUBJECT: Toxicity of Tetrahydrofuran
FROM: Robert Benson, Ph.D.
Toxicologist
TO:Loren Morton, Utah DEQ
Attached are toxicity assessments for tetrahydrofuran prepared by the Superfund
Technical Support Center, National Center for Environmental Assessment (Cincinnati). These
assessments were prepared in 1997 and include a provisional reference dose (RfD), a provisional
reference concentration (RfC), and a provisional cancer weight of evidence, slope factor (CSF),
and unit risk. Note that the oral values are based on a route-to-route extrapolation from an
inhalation study and that these provisional values have not received formal review by EPA.
Although scientists may disagree on the appropriateness of these provisional values, I would
recommend that you use them as screening values for your project rather than the value from the
MEPAS data base. It is my understanding that an EPA assessment for tetrahydrofuran for the
IRIS program is in progress. I do not know when the assessment documents will be publically
available.
The Drinking Water Program uses the equations below to derive a Lifetime Health
Advisory GHA) or to calculate a lifetime excess cancer risk using standard exposure
assumptions (a 70 kilogram body weight and consumption of 2 liters of warer a day). The
Relative Source Contribution (RSC) is used to account for potential exposure from routes other
than drinking water, typically food and air. The drinking water program typically uses an RSC in
the range of 0.2-0.8. The lower value is used when there is significant exposure from food or air
or there are no appropriate data for estimating exposure from sources other than drinking water.
LHA (mg/L) = RfD (mg/kg-day) x 70 kg x I dayl1 L x RSC
Lifetime Cancer Risk = CSF (mglkg-duy)'' x 2lJday x l/70 kg x Concentration (mgtL)
The provisional RfD is 0.2 mg/kg-day and the provisional oral Cancer Slope Factor is
7.6x10'3 (mglkg-day)'r. As tetrahydrofuran is quite voiatile and uses of the water in a residencewill increase the concentration of tetrahydrofuran in the air in the home, I recommend using 0.2
as the RSC. Using these values and the equations above, the LHA for tetrahydrofuran is 1.4mglL. The concentrations of tetrahydrofuran in drinking water corresponding to a I in 10,000,,{in:100;@o, and 1 in 1,000,000 cancer risk are 0.46 mglL;a.046 mg[L, and 0.0046 mg/L,
respectively

Derivation of a provisional RfI) for
Tetrahydrofuran (CASRN 109-99-9)
INTRODUCTION
No verified chronic RfD or RfC is available for tetrahydrofuran on IRIS (U.S. EpA, 1997) or HEAST(u's. EPA, 1995), and the U.s. EPA's CARA list (u.S. EpA;1994) does nor indicate any other documentsrelating to THF. ACGIH (1992,1996) has adopted a TLV-TWA of 200 ppm (590 mg/mi; and a STEL oi zsoppm (737 mgm') to protect workers against upper respiratory tract irritation and systemic effects (includingnarcosis) produced by tetrahydrofuran, osHA has established a pEL-TwA for tetrahydrofuran of 200 ppm-(osHA, 1993)- The NIosH REL-TWA is 200 ppm and the srEL is 250 ppm (NIOSH ,1992).
To identify research papers pertinent to the derivation of a provisional chronic RfD for tetrahydrofuran,computer searches of the literature were conducted from the HSDB, RTECS, TSCATS, MEDLINE, andTOXLINE (and its subfiles) databases, covering the time period of 1992-1997. The literature search wasconducted in September 1997.
REVIEW OF PBRTINENT LITERATURE
Human Toxicity Data
Garnier et al. (1989) reported two cases of workers who exhibited irritation of the mucous membranes,mild effects on the central nervous system, and cytolytic hepatitis following exposure to tetrahydrofuran. Bothworkers were plumbers who had been using glue containing tetrahydrofuran in confined spaces without wearingany protective devices. -one worker was exposed eight hours daily for three days, and the other was apparentlyexposed for only a few hours. symptoms in the workers includednausea, headache, blurred vision, dizziness,chest pain, and cough' conjunctival irritation was noted in one worker. Aspartate aminotransferase (AST) andalanine aminotransferase (ALT) activities in serum were elevate d to 3-25 times the upper limit of the normalrange in both workers, and in one worker, gamma glutamyl transferase (GGT) *as atso elevated to 9 times theupper limit of the normal range. The elevation of the liver enzymes, AST, ALT, and GGT is suggestive of aneffect of tetrahydrofuran on the liver. In both cases, liver.nry.". retumed to normal levels within two weeks.other accounts of tetrahydrofuran poisoning in workers have ieported similar effects (ACGIH, 1gg2; Garnier etal., 1989).

by repeated oral exposure (Komsta et al., 1988). Groups of 10 male and 10 female Sprague-Dawley rats weretreated with 0, 1, 10, 100, or 1000 mg/L of tetrahydrofuran in the drinking water for four weeks. Theresearchers calculated approximate doses of 0,0.1,0.8, 10.2 and 95.5 mg/kg-day in males and 0,0.1,0.1, 10.7,and 1 I l '3 mg/kg-day in females. clinical observations were made dailylan-d uoay weigtrt and food and waterintake were monitored weekly. The animals were sacrificed at the end of the .*porur. period. At necropsy,blood was collected for hematological and serum chemistry determinations, the major organs were weighed, andsamples from over 30 tissues were collected from the contiol and high-dose groups for histopathologicalexamination' Liver samples were assayed for activity of selected mixed function oxidases. All animalssurvived until scheduled sacrifice and no clinical signs oftoxicity were observed.
Food and water consumption and body weight gain in treated groups were similar to controls. Notreatment-related changes were reported for hematology, s"rum "n"mlstry, or trepaticenzyme activitydeterminations (data not shown). organ weight resulis were not reported. Histopathological examinationrevealed no changes other than an apparent increase in the incidenci of anisokaryosis (greater than normalvariability in size of nuclei) in the livers of female rats treated with 1000 mgrt. uowever, the toxicologicalsignificance of hepatic anisokaryosis is unclear. No other liver changes were reported. Therefore, this studyidentified a NoAEL of 1000 mg/L (95.5 mg/kg-day in males, t I 1.3 mglkg-aay in females) for shon-1"rmdrinking water exposure in rats.
Subchronic inhalation studies. The NTP sponsored a 13-week study to evaluate the cumulative toxiceffects of subchronic exposure to tetrahydrofuran and to determine tne approiriate concentrations to be used in a2-yeat study (NTP, in preparation; chhabra et al., 1990). Groups of 10/sex F344lN rats and B6c3F1 mice wereexposed to tetrahydrofuran at concentrations of 0, 66,200,600; 1g00, or 5000 pp- 10, tls ,5g0,17,79,5310, or14,750 mg/m3) by inhalation for 6 hours/day, 5 days/week, for 13 weeks. fte animals were weighed initially,weekly, and at the end of the studies. At thl ena or the exposure period, blood for hematology and clinicalchemistry was collected from all rats. A necropsy was performed on all animals. The heart, liver, lung, rightkidney, spleen, and thymus were weighed. A complete histopathological examination was performed onchamber controls and rats and mice receiving the highest dose.
All rats survived until the end of the study and final mean body weights were similar to controls. Maleand female rats in the 5000 ppm group exhibited ataxia (irregular movement with lack of coordination)immediately after the beginning of exposure. However, the Intensity of cNS toxicity a""r.ur"a with theduration of the exposure, suggesting a development of tolerance. Hematological anj bilchemical differencesbetween exposed animals and chamber controls were minimal with most values falling within physiologicalranges' and thus not considered toxicologically relevant. Absolute and relative thymul and spleen weights ofmale and female rats expo-sed to 5000 ppm were significantly less than controls, and absolute and relative liverweights (1880) were significantly increased in female rutr. Th" organ weight changes, however, were notaccompanied by histopathological changes. Though no exposure-related gross lesions were observed,significant increases in the incidence of foresto.ach hyperplasia in male (s4o) and female rats (g/10) wereobserved in rats receiving the highest dose. In two maii and four female rats, iuppur*ive inflammation wasassociated with the hyperplasia. The gastric lesions may have been due to the irrifunt effect of tetrahydrofuraningested during the exposure. Rats exposed to 5000 ppm had increased red blood cell counts, hemoglobin,volume of packed red cells, and mean corpuscular uotume. The males also had increased mean corpuscularhemoglobin and segmented neutrophil counts, and the females had increased platelet counts. However, the
@rrrrrrrm Rocycted paper
researchers attributed these hematological effects to dehydration in the high-exposure group. Female rats
exposed to 5000 ppm had increased bile acids (70Eo), plus decreased blood urea nitroge n (-4Vo) and creatinine
(-tUEo).
Mice were more sensitive than rats to inhaled tetrahydrofuran in this subchronic study (NTp, in
preparation; Chhabra et al., 1990). Three male mice died, one each in weeks 2,4, and8 in the 5000 ppm group.
In two of the mice that died, inflammation of the urinary tract was present. In the 5000 ppm grcup, rnice *".e
in a state of narcosis during the exposure and for 2 hours afterward. Similarly, in the 1800 pp. Sroup the mice
were in a state of narcosis during exposure, but were alert immediately after the end of the eiposure. The
intensity of the narcosis in the 1800 ppm group decreased with the duration of the experiment.
In female mice in the 5000 ppm group, the fatty vacuolar change that normally occurs in the inner cortex(X zone) of the adrenal gland was not present. Instead there was a degeneration of the X zone in all mice. Also,in female mice in the high-exposure group, the uteri were markedly smaller that normal. There were decreased
numbers of endometrial glands and decreased endometrial stroma, with the uterine muscle layers also thinner
than normal.
Thymus and spleen weights were decreased in mice in response to tetrahydrofuran exposure. Significant
reductions in thymus weights were observed in the 600 (l5vo),1800 (2ZVo),and 5000 (43%o)pp. g.oup-r, i,
male mice. However, no significant reductions in thymus weight were observed in femaler. -Spt""n *"igt ttwere reduced significantly in females (slEo) and males (38Vo) exposed to 5000 ppm tetrahyd.ofrran. Ho-wever,
no histopathological lesions were detected in either organ.
Reduced spleen and thymus weights were also reported in rats after subchronic exposure to
tetrahydrofuran (Chhabra et al., 1990; Katahira et al., 1982). Decreased spleen and thymus weight could
suggest a biologically important immunotoxicological effect, however, histopathological changis would be
expected to accompany the changes in organ weight. Thus, the observed changes in thymus and spleen weights
may be considered not to be a sufficiently significant toxicological response, and a LOIEL was not established
based on the reductions in spleen weight.
Significant increases in liver weights were observed in female mice exposed to 1800 (6Vo) and5000 ppm(l3%o), and in males exposed to 600 (6Vo),1800 (l3Vo),and 5000 ppm (25Vo). Histopathological change, *i."observed in the livers of mice in the high-dose groups. Minimal to mild centrilobular cytomegaly was observedin the livers of male (7110) and female (10/10) mice in the 5000 ppm group, and in one male mouse in the 1g00
ppm group. The lesion was characterized by an increased amount of cytoplasm and an increased size of some
hepatocyte nuclei. From this study a LOAEL of 1,800 ppm and a NOAEL of 600 ppm were chosen based on
the incidence of histopathological changes in livers of the male mice (Chhab.u et ut- 1990).
Another subchronic toxicity study was conducted by Katahira et al. (1982). In this study, groups of
1 1-12 male Sprague-Dawley rats were exposed to 0, 200, or 1000 ppm (0, 590, or 2950 mg/mri (s;ries j or 0,100, or 5000 ppm (0,295, or 14,750 mgm') (series tr) of tetrahydrofuran vapor, 4 hours/day, 5 days/week for
1 2 weeks. Rats were observed for clinical signs and body weight changes, and sacrificed on the second day
after the end of the l2-week exposure period. At necropsy, blood was collected for hematological and serumchemistry determinations, and the major organs were collected, weighed and processed for hiJtopathological

examination.
Signs of local irritation and nervous system depression were observed primarily in the rats exposed to5000 ppm' It was noted that the rats demonstrated increased tolerance to these effects as the experimentcontinued. Body weight gain was reduced throughout the experiment in the 5000 ppm group. Slight butstatistically significant changes in hematology and clinical chemistry paramerers occurreo, mostly in the 5000ppm dose group, but also to a limited extent in the 200 and 1000 ppm dose groups. These changes includedincreased serum glutamate-oxaloacetate transaminase, glutamate-pyruvate transaminase, cholinesterase, totalcholesterol and total bilirubin, and decreased blood sugar and teuiocyte count. Though collectively thesechanges suggest a toxic effect on the liver, none were of sufficient magnitude to clearly indicate a biologicallymeaningful effect. The relative weight of the brain, lungs, liver, pancreas, and kidneys were significantlyincreased in the 5000 ppm group, which the research"., utt ibut"d to the significant d""."ur" in body weight inthis group' However, even with the decrease in body weight, the relative weight of the spleen was decreased inthis group. No histopathological changes were detected in the liver or spleen, or any other tissue examined(kidneys, lungs, brain, and femur). Due to the limited effects at 1000 pim, this dose was considered to be aNOAEL, and 5000 ppm was considered a LOAEL.
Elovaara et al' (1984) exposed groups of 20 male wistar rats to tetrahydrofuran vapor at concentrationsof 0' 200, 1000 or 2000 ppm (0, 590, 2950, or 5900 mg/m3), 6 hours/day, 5 days/week for 2- l g weeks. Five ratsfrom each group were sacrificed after2,8, 13, and l8 weeks ofexposure, and tissues were assayed fortetrahydrofuran content (brain, perirenal fat) and/or certain enzyme activities (liver, kidney, gluteal muscle,brain)' The tetrahydrofuran concentration in brain and perirenal fat tissues was linearlf correlated with exposureconcentration, though tissue concentrations declined with increasing exposure time, stiggesting that degradationof tetrahydrofuran was enhanced. The rate of decline was most marked'in the 200 pprrig.oup. Body weightgain in exposed rats did not differ from controls. Liver to body weight ratio was atso unaffected. However,hepatic and renal 7-ethoxycoumarin deethylase activities wereincreased throughout the study in all treatedgroups' and after l8 weeks, liver microsomal protein content was increased thrlughout, accompanied by anincrease in NADPH-cytochrome c reductase and decreases in alcohol dehydrogenase and formaldehydedehydrogenase at 2000 ppm. In muscle, succinate dehydrogenase and aceiylcholine esterase activities wereincreased in a dose-related fashion after l8 weeks. No biochemical changes were noted in the brain. Theauthors considered these results to suggest that subchronic exposure to 200 ppm or more oftetrahydrofuran canaffect energy metabolism and myoneural activity. However, th" ,"port"d effects are mild. and theirtoxicological significance is unclear. NOAEL and LOAEL values were not derived.
Chronic inhalation study. AZ-year chronic inhalation exposure study using male and female F344nlrats and B6c3Fl mice was conducted by NTP (in preparation). No other chroni" "*io.u." studies were found.
Groups of 50 male and female F344aI rats and B6c3Fl mice were exposed to 0, 200, 600, or l g00 ppm(0, 590, 1770, or 5310 mg/m3) tetrahydrofuran by inhalation, 6 hours/day, 5 days/week for 105 weeks. Theoverall purity was determined to be approxim ately 99vo, and the peroxide concentrations no greater than 3 ppm.All animals were observed twice daily. clinical fi^n_dings and boiy weights were recorded weekly for l2weeks(rats) or l3 weeks (mice), monthly through week 91 (rats) or *."k 9z (irice),
^na "|"ry-zweeks until the end ofthe study' complete necropsies and histopathological examinations of a wide range of tissues and organs wereperformed on all rats and mice' However, organ weights were not measured, and is no blood samples were

collected, no hematological and clinical chemistry analyses were performed. Animals found dead due to
accidents were censored from the survival analyses, but animals dying from natural causes were included. The
data were subjected to rigorous statistical analysis by standard procedures.
Estimates of Z-year survival probabilities and Kaplan-Meier survival curves indicated that survival of
male and female rats exposed to tetrahydrofuran was similar to chamber controls. Survival of female rats to thefinal sacrifice was approximately SD%o,butsurvival of males varied from 10 to24Vo. Although survival of male
rats to the final sacrifice in chamber controls was higher than in the tetrahydrofuran-exposed groups, survival at75 weeks was greater thang}Vo in all groups with the differences among groups only ernerging aft". 100 weeks.
Thus, tetrahydrofuran exposure did not significantly reduce the survival of rati of either sex. Mean bodyweights were similar to chamber controls throughout the study. No clinical findings related to tetrahydrofuran
exposure were found, and no non-neoplastic lesions were found in either male or female rats at concentrations
up to I 800 ppm tetrahydrofuran after 105 weeks of exposure.
After 36 weeks, the survival of male mice exposed to 1800 ppm was significantly lower than that of thechamber controls. The average life span for controls was 689 days, while the life span of mice in the lg00 ppmgroup was reduced to 456 days. Survival of males at200 and 600 ppm and of all females was similar to th;
chamber controls. Mean body weights of male and female mice were similar to those of the chamber controlsthroughout the study, and no clinical findings related to exposure to tetrahydrofuran wbre observed in femalemice' However' males exposed to 1800 ppm were observed in a state of narcosis during exposure and up to Ihour afterward. The mice were limp, with their feet hanging through the cage floor, anJ thelr preputial drr waswet with urine. At the time of the selection of the exposure concentrations ior the 2-yeu study, ii was predicted
that an observed increase in tolerance during a subchronic study might result in "o*il"t" tolerance to the
sedative effects of tetrahydrofuran. This prediction was clearly incorrect, and 26 of ihe male mice in the l g00
ppm group died during the first year of exposure.
Male mice exposed to 1800 ppm tetrahydrofuran had significantly greater incidences of non-neoplastic
lesions of the urogenital tract than chamber controls. These lesions (which occurred primarily among the 26
animals that died during the first year of the study) included suppurative inflammation of the kidney, urinarybladder, prostate gland, and preputial skin; hydronephrosis ofthe kidney; and transitional epitheliaitryperptasia
of the urinary bladder. The inflammatory urogenital tract lesions were considered to be the most tikeiy cause ofthe lower survival rate observed in this exposure group. The authors speculated that prolonged wetting of thepreputial fur during exposure-related narcosis may have predisposed these animals to a preputial bacterialinfection that subsequently ascended the urogenital tract resulting in moribundity and uliimately death.
Increased incidences of hyperplasia of the bone marrow, hematopoietic cell proliferation of the spleen, andthymic atrophy also were observed in the 1800 ppm exposed male mice. Thlse changes were considered to besecondary reactive responses to acute inflammation of the urinary and urogenital tracts that were of marginalsignificance.
The 2-year chronic tetrahydrofuran inhalation study did not reveal any non-neoplastic systemic effects ineither rats or mice. The 1800 ppm concentration clearly exceeded the maximum tolerated dose for maleB6C3FI mice, due to the sedative effects of tetrahydrofuran. No histological damage to the nervous system was

observed, and the deaths of these mice were attributed to development of urogenital tract bacterial infections asa secondary effect ofthe prolonged sedation ofthese animals.
Developmental and reproductive studies. Mast et al. (1992) studied the developmental toxicity oftetrahydrofuran in rats and mice. Groups of 30 mated and 10 virgin young adult female Sprague-Dawley ratswereexposedto0,600, 1800or5000ppm(0, 1770,5310,or14,750mgmr)of tetrahydrofuranvapors,6hours/day on gestation days (GD) 6-19. Body weight, clinical signs, pregnancy rate, implantation, and fetalsurvival, growth, and morphology were monitored. Pregnant rati were sacrificed on GD 20, andvirgin ratswere sacrificed the day after the last exposure.
Cumulative body weight gain was significantly reduced throughout the exposure period in the pregnantrats exposed to 5000 ppm' an effect was not found in virgin rats exposed at the same concentration. ftre ontyother maternal effect noted was mild alopecia in a few dams from the three tetrahydrofuran-exposed groups,which the researchers attributed to the irritant properties of the chemical. The oniy developmental efiect in ratswas a significant reduction in fetal weight (mean of litter means) in the 5000 ppm group (to g2vo of controlvalues). Therefore, 1800 ppm was the NOAEL. and 5000 ppm was the LOAEL for both maternal anddevelopmental effects in rats in this study.
In the mice, groups of 30 mated and l0 virgin young adult female Swiss (CD-l) mice were exposed to 0,600, 1800, or 5000 ppm (0, 1770, 5310, or 14,750 mg/m') of tetrahydrofuran vapors, 6 hours/day on GD 6-17.Pregnant mice were sacrificed on GD 18, and virgin mice were sacrificed the day after the last exposure.
Mortality was high among pregnant and virgin mice exposed to 5000 ppm (30Vo after 5 exposures).survivors from this group were removed from treatment after "*porrr" day 5-and held until scheduled sacrifice.Death was attributed to severe depression of the nervous system. Narcosis was observed in all mice exposed to5000 ppm and also some exposed to 1800 ppm. In addition, body weight gain was significantly reduced in boththe 1 800 and 5000 ppm groups, possibly due to decreased uterine weight (issociated inith ir"..ured intrauterinemortality).
Developmental effects included significant reductions in the number and percent of live fetuses/litter andsignificant increases in the number and/or percent of early resorptions per litter in bottr the 1g00 and 5000 ppmgroups' In the 5000 ppm group, the 20 dams that survived the exposure period collectively produced onty tnelitter containing live fetuses. This study identified NOAELs or t gOO ppm for maternal toxicity and 600 ppm fordevelopmental toxicity in mice.
The developmental toxicity of tetrahydrofuran in rats was also reported by Dupont (lggz). The studywas conducted in two parts. Initially, groups of seven (14 in control group) mated female Crl:CD rats wereexposed to 0, 200, 500, 2500 or 5000 ppm (0, 5go, 1475,7375, or rulso- mgm3) of tetrahydrofuran vapor for 6hours/day on GD 6-15. Subsequently, groups of 29 or more mated females i"r.'"*por"d with the sameregimen to 0, 1000 or 5000 ppm (0, 2950, or 14,750 mg/m'). Dams were sacrificed on GD 21. Body weight,feed consumption, clinical signs, pregnancy rate, implantation, and fetal survival, growth, and morphology weremonitored. Results were combined for all data obtained after scheduled sacrifice, -b""uu."
the two part, oi tfr"study were conducted identically and the data obtained were similar. During the exposure period, both maternalfood consumption and body weight gain were significantly reduced in the 5d00 pprn group. kthargy and ataxiawere also noted in these dams. Dams exposed to 2500 and 1000 ppm displayed-mild-narcosis (rediced response

to noise stimulus). Developmental effects were limited to the 5000 ppm group and included a significant
decrease in fetal weight and a significant increase in the incidence of fetuses with structural variations(unossified and partially ossified sternebrae). This study, therefore, identified a maternal NOAEL of 500 ppm
and LOAEL of 1000 ppm, and a developmental NOAEL and LOAEL of 2500 and 5000 ppm, respectively.
No multigeneration reproduction studies were located.
Pharmacokinetics
There is little information available on the pharmacokinetics of tetrahydrofuran. Absorption through thelungs in human volunteers ranged from 60-807o depending upon the breathing rate and concentration oftetrahydrofuran (Kageyama, 1988; Teramoto et al., 1988). Estimates of oral absorption rates are not available.
The urine concentration of videotape manufacturing workers at the end of their work shift was correlated (r=0.88) with exposure measured by personal sampling dosimetry (Ong et al., l99l). The correlation betweendosimetry and the exhaled breath and blood concentrations (r=0.61 and 0.68, respectively) was lower. In aninhalation study in rats (Elovaara et al., 1984), there was a linear correlation between tetiahydrofuranconcentrations in air and those in brain and perirenal fat. As noted earlier, after two weeks, the body burdendecreased with exposure time, suggesting that oxidative metabolism of tetrahydrofuran may have been inducedby continued exposure. Increased 7-ethoxycoumarin O-deethylase activity *a. meusu."d in the liver andkidneys.
The metabolic degradation pathways for tetrahydrofuran have not been elucidated (Moody, l99l). Fujitaand Suzuoki (1973) showed that tetrahydrofurfuryl mercaptan was metabolized to4-hydroxy-5-methylsulfonylvaleric acid by liver microsomes and cytosol. Also, incubation of tetrahydrofuranwith activated liver supernatant resulted in generation of formaldehyde, suggesting a mixed function oxidasereaction (Kawalek and Anders, l9s0). However, the metabolites of tetrahyJrofuran in biological systems havenot been fully elucidated (Moody, l99l). Following inhalation exposure, unmetabolized tetrahydrofuran waseliminated in the exhaled air and the urine (Kageyama, lggg; Ongit al., l99l).
DERIVATION OF A PROVISIONAL ORAL RfD
The only repeated-exposure oral study available is the 4-week drinking water study in rats by Komsta etal. (1988). This study detected no adverse effects at the highest dose level tesied, 1000 mg/L (95.5 mg/kg-dayin males, 1 I 1.3 mg/kg-day in females), making that dose a NOAEL. However, the short duration or t[isituaymakes it unsuitable for use as the basis for RfD derivation.
No non-neoplastic lesions were detected by histopathological examination of rats and mice in a chronic(1O5-week) exposure to 0,200,600, or 1800 ppm tetrahydrofuran (NTp, in preparation). Thus, there was noindication that the centrilobular hepatocytomegaly observed in male and female mice during the l3-weekexposure to 5000 ppm and in one male mouse at 1800 ppm occured at lower exposures during chronicexposure. Organ weights, hematological parameters, and blood chemistry p*u*at"rr, also, were not measuredin the chronic study. Thus, the chronic exposure study provided no furtheidelineation ofthe increased absoluteand relative liver weights and decreased absolute and relative thymus weights observed in male mice exposed to600, 1800, and 5000 ppm tetrahydrofuran for 13 weeks or increased serum bile acids in high-dose female rats
&prnt"a o, Recycled paper
(Chhabra et al., 1990; NTP, in preparation).
A provisional RfD for tetrahydrofuran can be calculated based on liver effects in mice exposed totetrahydrofuSn by inhalation for 13 weeks (Chhabra et al., 1990). The NOAEL for this effect was 600 ppm(1770 mglm3) and the LIAEL was 1800 ppm (5310 mdm3) based on the occurrence of hepatic cytomelaty anoincreased liver weight. The 600 ppm concentration was considered a NoAEL despite marginallyir"r"^"i liu",weight, because the increase in liver weight was slight (6vo) andno accompanying tristopatrrotogy was noted.
It is possible that the liver changes identified in mice in this study could be consistent with an adaptive,rather than toxic, response to tetrahydrofuran. However, case reports of occupationally exposed workers(Gamier et al., 1989), acute studies in laboratory animals (Moody, lggl), and subchronic studies in rats(Chhabra et al., 1990; Katahira et al., 1982) all found evidence oi a toxic effect on the liver produced bytetrahydrofuran' Therefore, use of this endpoint was considered to be appropriate for derivaiion of a provisionalRfD.
The NoAEL of 600 ppm is supported by the available database of inhalation studies. Subchronicstudies in rats had NoAELs of 1000 ppm (Katahira et al., 1982) and 1800 ppm (Chhabra et al., 1990). Studiesof developmental toxicity showed that the developing fetus is not a specifi. i*g"t for tetrahydrofuran. Mast etal. (1992) determined NOAELs of 600 ppm for mice and 1800 ppm for rats for both maternat anddevelopmental effects, while DuPont (1982) determined a NOAEL of 500 ppm for maternal effects and aNoAEL of 2500 ppm for developmental effects in rats. Althougtr tetrarryaiofuru, can be a respiratory irritant,local irritation was not identified as a critical effect in the subchionic studies.
A provisional RfD can be calculated as follows:
conversion of the NoAEL in ppm to a NoAEL in mglm3 (using ppm x Mwlz4.45) giving, for aNOAEL of 600 ppm:
600x72.U24.45 = 1770 mgtm3
derivation of NoAELrwa based on the dosing regimen of 6 hours/day, 5 days/week:
1770 x 6t24 x 517 = 3t6mgm3
conversion of the NOAELT*A (3 l6 mg/m3) to an inhaled dosero,." using:
1) a default absorption factor of I2) a default inhalation rate of 0.053 m3lday (U.S. EpA, 19g7)3) a default body weight of 0.0316 kg (U.S. EpA, 1987)

assuming a default value of I for the ratio of inhalation:oral absorption factors given a lack of data, the

equivalent oral dose remains 530 mg/kg-day.
. The provisional oral chronic RfD = equivalent oral doseAIF
530/3000 = 0.18 mg/kg-day =28-l mg/kg-day
where:
UF is the uncertainty factor, reflecting factors of l0 for use of a subchronic study, 3 for extrapolation
from mice to humans, 10 for database limitations including route,to-route extrapolation and lack of
pharmacokinetic and multigeneration reproduction studies, and l0 for protection of sensitive
subpopulations.
The equivalent oral dose (NOAEL) of 530 mg/kg-day is approximately 5 times grcater than the NOAEL
of roughly 100 mg/kg-day derived from the 4-week drinking water study by Komsta et al. (1988). However, theNOAEL from the Komsta et al. (1988) study was based on no adverse effect at any dose tested; a LOAEL was
not identified. Therefore, the existing oral data are not in conflict with this provisional RfD derivation.
For this provisional RfD, confidence in the key study is high. The study was well-designed, thoroughly
documented, and carefully conducted. It included two different species and identified a NOAEL anO LOegL
for each. Confidence in the database is low because no suitable oral data were available; only very limited
pharmacokinetic data were available and no multigeneration reproduction studies were available. Thus,
confidence in the provisional RfD is low.
Risk Characterization
The results of theZ-year chronic inhalation study showed that there was some evidence of carcinogenic
activity of tetrahydrofuran in male F3444{ rats due to increased incidence of adenoma and carcinoma
(combined) of the kidney (NTP, in preparation). There was no evidence of carcinogenic activity in female
F344n'I rats and male B6C3F1 mice. There was clear evidence of carcinogenic activity in female B6C3F1 mice
due to increased incidences ofhepatocellular neoplasms. These responses, taken together, were used as the
basis for a provisional weight-of-evidence classification for the compound's carcinogenicity, while the
incidence of combined adenomas and carcinomas in mice have been used to derive carcinogenic slope factors
and unit risk values in a separate risk issue paper.
For non-cancer evaluations, the validity of the primary toxicological response (hepatocytomegaly) of
male B6C3FI mice to subchronic exposure to tetrahydrofuran to serve as a basis for developing a chionic RfD
and RfC for the compound depends upon the extent to which such a response may either (li represent aprecursor condition for the development of adenoma and/or carcinoma that became evident in the 2-year
inhalation study, or (2) represent a solely non-neoplastic response independent of tumor initiation ani
development. Only in the second case would the response be applicable for developing quantitative toxicity
benchmarks such as the RfD and/or RfC.
In the 2-year study, other than a general statement that there was no evidence of non-neoplastic
Srnnr", o, Recyctod paper
LrIcil tvturlun - Mononl.vvl-u
histopathological lesions in mice exposed to tetrahydrofuran for two years, no data were presented on theincidence of hepatocytomegaly in male or female B6C3FI mice (NTi, in preparation). However, this broadstatement provides a strong implication of a potential etiological disconnect b"tru""n the histopathologicalresponse observed in the l3-week study and the incidence of combined adenomas/carcinomas in the livers of theanimals receiving tetrahydrofuran for two years.
Furthermore, the incidence of hepatocytomegaly in the l3-week study was observed primarily in the5000 ppm exposure group (Chhabra et al., 1990; NTP, in preparation). Minimal to mild centrilobularcytomegaly was observed in the livers of male (7/10) and female (10/10) mice in the 5000 ppm group, and inone male mouse in the 1800 ppm group. The 5,000 ppm concentration level was not employeo in ttre Z-yearstudy, because this level induced ataxia in rats and sedation in both sexes of mice throughout the exposureperiod' Treatment levels that result in significant increases in abnormal behavior may be considered to indicatethat an adequate high dose for carcinogenicity testing has been exceeded (u.s. EpA, '1996).
The lg00 ppmtetrahydrofuran concentration also caused sedation in male mice in the 13-week study (Chhabra et al., 1990)throughout the2'year inhalation exposure study (NTP, in preparation). Accordingty, ttre incidence oftetrahydrofuran-induced hepatocytomegaly was limited to exposure concentrations that exceeded the maximumtolerated dose in long-term studies.
The hepatocytomegaly reported in mice in the 13-week study was characterized by an increased amountof cytoplasm and an increased size of some hepatocyte nuclei (Chhabra et al., 1990; NTp, in preparation).However, though increase in cell division would be anticipated in pre-neoplastic lesions, no increase in celldivision was indicated in the observations of hepatocytomegaly. The lack of increased cell division implies thathepatocytomegaly is not a pre-neoplastic lesion.
lndirect inferences that illuminate this issue may be drawn from other NTp chronic toxicology andcarcinogenesis studies in which both endpoints were reported for the chronically-exposed animals. Forexample, in an NTP study in which B6C3FI mice were exposed to two pentachorophenol technical-grademixtures in feed for two years (NTP, 1989), the incidenceJ of a range of non-neoplastic histopathololicatresponses were recorded' in addition to those of a comprehensive list of tumorig"ri" ,"rponses. Among the keycarcinogenic responses that served as a basis for the identification of the pentaclhlorophenol preparations ascarcinogens was the increased incidence of tumors of the adrenal gland medulla and of combined adenomas andcarcinomas of the liver.
Two lines of evidence from these data allow a distinction to be drawn between the incidences ofhepatocytomegaly and liver tumor formation: (1) a (well recognized) and significant incidence ofadenoma'/carcinoma formation was evident in control male mice in the comflete absence of hepatocytomegaly,and (2) pentachlorophenol-receiving animals displayed l\Ovo incidence of hepatocytomegaly in circumstanceswhere the incidence of tumors was considerably less. Taken together, these findinls point markedly to theconclusion that the hepatocytomegalic response is likely to reprisent a true non-neoplastic lesion, divorced fromthe tumorigenic response evident in the livers of male and female mice exposed foriwo years.
Accordingly, by analogy to the pentachlorophenol studies, the quantitative data on the onset of
&rrrr"oo, Recycted paper
hepatocytomegaly in response to subchronic exposure to tetrahydrofuran are considered to be appropriate for the
development of non-cancer quantitative toxicity benchmarks such as the chronic RfD and RfC sincJ they are
unlikely to represent a precursor condition for the tumorigenic rcsponses evident in the livers of mice after two
years exposure.

Derivation of a provisional RfC for
Tetrahydrofuran (CASRN f 09-99-9)
INTRODUCTION
No verified chrolic-RfD or RfC is available for tetrahydrofuran on rus ru.s. EpA, lggT)or HEAST(u's' EPA, 1995), and the U's. EPA's CARA list (u.s. EpA; 1994) does not indicate any other documentsrelating to THF. ACGIH (1992,1996) has adopted a TLV-TWA of 200 ppm (590 .g.1) ano a srei "iisoppm (737 m/m3) to protect workers against upper respiratory tract ioit tion ana sys;ic effects (includingnarcosis) produced by tetrahydrofuran. osHA has establistred a PEL-TWA for tetrahyJrofuran of 200 ppm(osHA, 1993). The NIOSH REL-TWA is 200 ppm and the srEL is 250 ppm (Nlosi{, rgg2).
To identify research papers pertinent to the derivation ofa provisional chronic RfC fortetrahydrofuran,computer searches of the literature were conducted from the HSDB, RTECS, TscATS, MEDLINE, andToXLINE (and its subfiles) databases, covering the time period of 1992-1997. The literature search wasconducted in September 1997.
RBVIEW OF PERTINENT LITERATURE
Human Toxicity Data
Garnier et al. (1989) repoted two cases of workers who exhibited irritation of the mucous membranes,mild effects on the central nervous system, and cytolytic hepatitis following exposure to tetrahydrofuran. Bothworkers were plumbers who had been using glue containing tetrahydrofuran in^confined spaces without wearingany protective devices. .one worker was exposed eight houis daily for three days, and the other was apparentlyexposed for only a few hours. Symptoms in the workers includednausea, headache, blurred vision, dizziness,chest pain, and cough. conjunctival irritation was noted in one worker. Aspartate aminotransferase (AST) andalanine aminotransferase (ALT) activities in serum were elevate d to 3-25 times the upper limit of the normalrange in both workers, and in one worker, gamma glutamyl transferase (GGT) was also elevated.to 9 times theupper limit of the normal range. The elevation of the livei enzymes, AST, ALT, and GGT is suggestive of aneffect of tetrahydrofuran on the liver. In both cases, liver enzymes returned to normal levels within two weeks.other accounts of tetrahydrofuran poisoning in workers have ieported similar effects (ACGIH, 1gg2; Garnier etal., 1989).
Animal Toxicity Data
subchronic inhalation studies. The NTP sponsored a 13-week study to evaluate the cumulative toxiceffects of subchronic exposure to tetrahydrofuran and to determine the appropriate concentrations to be used in a2-year study (NTP, in preparation; chhabra et al., 1990). Groups of lO/sex F344lrl rats and B6c3Fl mice were
$rr,nr"o on Recycted paper
exposed to tetrahydrofuran at concentrations of0, 66,200,600, 1g00, or 5000 ppm (0, l95, 5g0, 177g,5310, or14,750 mg/m3) by inhalation for 6 hours/day, 5 days/week, for l3 weeks. the animals were weighed initially,weekly, and at the end of the studies' At the end of the exposure period, blood for hematology and clinicalchemistry was collected from all rats. A necropsy was performed on all animals. The heart, liver, lung, rightkidney, spleen, and thymus were weighed. A complete histopathological examination was performed onchamber controls and rats and mice receiving the highest dose.
AII rats survived until the end of the study and final mean body weights were similar to controls. Maleand female rats in the 5000 ppm group exhibited ataxia (irregular movement with lack of coordination)immediately after the beginning of exposure. However, the intensity of cNS toxicity decreased with theduration of the exposure, suggesting a development of tolerance. Hematological anj biochemical differencesbetween exposed animals and chamber controls were minimal with most values falling within physiologicalranges, and thus not considered toxicologically relevant. Absolute and relative thymul and spleen weights ofmale and female rats exposed to 5000 ppm were significantly less than controls, and absolute and relative liverweights (lgEo) were significantly increased in female rats. The organ weight changes, however, were notaccompanied by histopathological changes. Though no exposure-related gross lesions were observed,significant increases in the incidence of forestomuih hyperplasia in male fJ4o) and female rats (g/10) wereobserved in rats receiving the highest dose. In two mate und for. female rats, suppurative inflammation wasassociated with the hyperplasia. The gastric lesions may have been due to the irritant effect of tetrahydrofuraningested during the exposure. Rats exposed to 5000 ppm had increased rea uroJceit "ourtr, hemoglobin,volume of packed red cells, and mean corpuscular uolurne. The males also had increased mean corpuscularhemoglobin and segmented neutrophil counts, and the females had increased platelet counts. However, theresearchers attributed these hematological effects to dehydration in the high-eiposure group. Female ratsexposed to 5000 ppm had increased bile acids (Tovo),plus decreased bloo--d urea nitrogi n (-4vo)and creatinine(-107o).
Mice were more sensitive than rats to inhaled tetrahydrofuran in this subchronic study (NTp, inpreparation; Chhabra et al., 1990). Three male mice died, one each in weeks 2,4, andg in the 5000 ppm group.In two of the mice that died, inflammation of the urinary tract was present. In the 5000 ppm group, mice werein a state of narcosis during the exposure and for two hours afterwird. Similarly, in trre i go0 ppm group themice were in a state of narcosis during exposure, but were alert immediately after the end of the exposure. Theintensity of the narcosis in the 1800 ppm group decreased with the duration of the experiment.
In female mice-in the 5000 ppm group, the fatty vacuolar change that normally occurs in the inner cortex(X zone) of the adrenal gland was not present. Instead there was a degeneration of thl X zone in all mice. Also,in female mice in the high-exposure group, the uteri were markedly smaller than normal. There were decreasednumbers of endometrial glands and decreased endometrial stroma, with the uterine muscle layers also beingthinner than normal.
Reduced spleen and thymus weights were also reported in rats after subchronic exposure totetrahydrofuran (chhabra et al., 1990; Katahira et al., 19i2). Decreased spleen and thymus weight couldsuggest a biologically important immunotoxicological effect, however, histopathological changes would beexpected to accompany the changes in organ weight. Thus, the observed changes inihymus and spleen weights
&rr,nr"o on r"cycted paper
may be considered not to be a sufficiently significant toxicological response, and a LSAEL was not establishedbased on the reductions in spleen weight.
significant increases in liver weights were observed in femare mice exposed to 1g00 (6vo) and5000 ppm(l3vo), and in males exposed to 600 (6vo),1800 (l3vo),and 5000 ppm (25vo). Histopathological changes wereobserved in the livers-of mice in the high-dot" groupr. Minimal to mild centrilobular cytomegaly was observedin the livers of male (7t10) and female (10/10) ,ni"" i, the 5000 ppm group, and in one male mouse in the lg00ppm group' The lesion was characterized by an increased amounior cytoplur1n and an increased size of somehepatocyte nuclei. From this study a LoAEL of 1800 ppm and a NoAEL of 600 ppm were chosen based on theincidence of histopathological changes in livers of the male mice (Chhabra et al., i qqol.
Another subchronic toxicity study was conducted by Katahira et al. (19g2). In this study, groups ofll-12 male Sprague-Dawley rats were exposed to 0, 200, oi 1000 ppm (0, 590, or 2950mg/mr) (series I) or 0,100' or 5000 ppm (0,295, or 14,750 */r'l (series_tr) of tetrahydiofuran vapor, 4 hours/day, 5 days/week forI 2 weeks' Rats were observed for clinical signs and body weight changes, and sacrificed on the second dayafter the end of the l2-week exposure period. At necropsy, blJod was iollected for hematological and serum
:filil#**rminations, and the major organs were collicted, weighed, and processeJ ro. n[toputhotogical
Signs of local irritation and nervous system depression were observed primarily in the rats exposed to5000 ppm' It was noted that the rats demonstrated increased tolerance to these effects as the experimentcontinued' Body weight gain was reduced throughout the experiment in the 5000 ppm group. slight butstatistically significant changes in hematology and clinical chemistry parameters occurred, mostly in the 5000ppm dose group, but also to a limited extent in the 1000 and 200 ppm dose groups These changes includedincreased serum glutamate-oxaloacetate transaminase, glutamate-pyruru," transaminase, cholinesterase, totalcholesterol and total bilirubin, and decreased blood sug-ar and leukocyte count. Though collectively thesechanges suggest a toxic effect on the liver, none were of sufficient magnitude to clearly indicate a biologicallymeaningful effect' The relative weight of the brain, lungs, liver, pancreas, and kidneys were significantlyincreased in the 5000 ppm group, which the researchers attributed to th" significant d""."ur" in body weight inthis group' However, even with the decrease in body weight, the relative weight of the spleen was decreased inthis- group' No histopathologrcal changes were detectea in ttre liver or spleen, or any other tissue examined(kidneys, lungs, brain, and femur). Due to the limited effects at 1000 ppm, this dose was considered to be aNOAEL, and 5000 ppm was considered a LOAEL.
Elovaara et al' .(1984) exposed groups of 20 male wistar rats to tetrahydrofuran vapor at concentrationsof 0' 200' 1000, or 2000 ppm (0, 590, 2950, or 5900 mg/m3) 6 hours/day, 5 days/week for 2-l g weeks. Five ratsfrom each group were sacrificed after 2,8, 13, and 18 ieets of exposure, and tissues were assayed fortetrahydrofuran content (brain, perirenal fat) and/or certain enzymeactivities (liver, kidney, gluteal muscle,brain)' The tetrahydrofuran concentration in brain and perirenal fat tissues was linearly correlated with exposureconcentration, though tissue concentrations declined wiih increasing exposure time, suggesting that degradationof tetrahydrofuran was enhanced. The rate of decline was most marked in the 200 ppm group. Body weightgain in exposed rats did not differ from controls. Liver to body *"igt, ratio was utro ururr""hd. However,
@rnrr"o o, Becycted paper
hepatic and renal 7-ethoxycoumarin deethylase activities were increased throughout the study in all treatedgroups, and after 18 weeks, liver microsomal protein content was increased throughout, accompanied by anincrease in NADPH-cytochrome c reductase and decreases in alcohol dehydrogen-ase and formaldehyde
dehydrogenase at 2000 ppm. In muscle, succinate dehydrogenase and aceiylcholine esterase activities wereincreased in a dose-related fashion after 18 weeks. No biochemical changes were noted in the brain. Theauthors considered these results to suggest that subchronic exposure to 200 ppm or more of tetrahydrofuran canaffect energy metabolism and myoneural activity. However, the reported effects are mild and their toxicologicalsignificance is unclear. NOAEL and LoAEL values were not derived.
Chronic inhalation study. AZ'year chronic inhalation exposure study using male and female F344lNrats and B6C3FI mice was conducted by NTP (in preparation). No other chroni. .*f,oru." studies were found.
Groups of 50 male and female F344 ,1 rats and B6C3FI mice were exposed to 0, 200, 600, or l g00 ppm(0, 590, 177o, ot 5310 mg/m3) tetrahydrofuran by inhalation, 6 hours/day, 5 days/week for 105 weeks. Theoverall purity was determined to be approxim ately 99vo, and the peroxide concentrations no greater than 3 ppm.All animals were observed twice daily. Clinical findings and body weights were recorded weekly for l2*""t,(rats) or 13 weeks (mice), monthly through week 91 (rats) or week 92 lmice), and every two weeks until the endof the study' Complete necropsies and histopathological examinations of a wide range of tissues and organswere performed on all rats and mice. However, organ weights were not measured, and as no blood ru111pl",were collected, no hematological and clinical chemistry analyses were performed. Animals found dead due toaccidents were censored from the survival analyses, but animals dying irom natural causes were included. Thedata were subjected to rigorous statistical analysis by standard procedures.
Estimates of 2-year survival probabilities and Kaplan-Meier survival curves indicated that survival ofmale and female rats exposed to tetrahydrofuran was similar to chamber controls. Survival of female rats to thefinal sacrifice was approximately S\vo,but survival of males varied from l0 to 24vo. Although survival of malerats to the final sacrifice in chamber controls was higher than in the tetrahydrofuran-exposed groups, survival at75 weeks was greater thartg}vo in all groups with the differences among $oups only emerging after 100 weeks.Thus, tetrahydrofuran exnosure did not significantly reduce the survival of rati of eiiher sex. Mean bodyweights were similar to chamber controls throughout the study. No clinical findings related to tetrahydrofuranexposure were found, and no non-neoplastic lesions were found in either male or female rats at concentrationsup to 1800 ppm tetrahydrofuran after 105 weeks ofexposure.
After 36 weeks, the survival of male mice exposed to 1800 ppm was significantly lower than that of thechamber controls. The average Iife span for control mice was 689 days, whileihe life span of mice in the lg00ppm group was reduced to 456 days. Survival of males at 200 and 600 ppm and of dl flmales was similar tothe chamber controls- Mean body weights of male and female mice were similar to those of the chambercontrols throughout the study, and no clinical findings related to exposure to tetrahydrofuran were observed infemale mice. However, males exposed to 1800 ppm were observed in a state of narcosis during exposure andup to one hour afterward. The mice were limp, with their feet hanging through the cage floor, and theirpreputial fur was wet with urine. At the time of the selection of the exposure concentrations for the Z-yearstudy, it was predicted that an observed increase in tolerance during a subchronic study might result in completetolerance to the sedative effects of tetrahydrofuran. This prediction was clearly incorrict, and 26of the malemice in the 1800 ppm group died during the first year of ixposure.

Male mice exposed to 1800 ppm tetrahydrofuran had significantly greater incidences of non-neoplasticlesions of the urogenital tract than chamber controls. These lesions (which occurred primarily among the 26animals that died during the first year of the study) included suppurative inflammation of the kidney, urinarybladder, prostate gland, and preputial skin; hydronephrosis oftirl kidney; and transitional epithelial hyperplasiaof the urinary bladder' The inflammatory urogenitai tract lesions were considered to be the most likely cause ofthe lower survival rate observed in this exposure group. The authors speculated that prolonged wetting of thepreputial fur during exposure-related narcosis m.y t are predisposed these animals to a preputial bacterialinfection that subsequently ascended the urogenital tractiesulting in moribundity and ultimately death.Increased incidences of hyperplasia of the bone marrow, hematopoietic cell proliferation of the spleen, andthymic atrophy also were observed in the 1800 ppm exposed maie mice. Thlse changes were considered to besecondary reactive responses to acute inflammation of ihe urinary and urogenital tracis that were of marginalsignificance
The2-year chronic tetrahydrofuran inhalation study did not reveal any non-neoplastic systemic effects ineither rats or mice' The 1800 ppm concentration clearly exceeded the maximum tolerated dose for maleB6c3Fl mice, due to the sedative effects of tetrahydroiuran. No histological damage to the nervous system wasobserved' and the deaths of these mice were attributed to development of urogenital tract bacterial infections asa secondary effect of the prolonged sedation of these animals.
Developmental and reproductive studies. Mast et al. (1992)studied the developmentaltoxicity of tetrahydrofuran in rats and mice. Groups of 30 mated and 10 virgin young adult femaleSprague-Dawley rats were exposed to 0, 600, 1g00, or 5000 ppm (0, tllo, ilt6, ori4,75omg/m3) oftetrahydrofuran vapors 6 hours/day on gestation days (GD) o-iq. noay weight, clinicai signs, pregnancy rate,implantation, and fetal survival, growth, and morphology were monitored. Fregnant rats were sacrificed on GD20, and virgin rats were sacrificed the day after thi last-exposure.
cumulative body weight gain was significantly reduced throughout the exposure period in the pregnantrats exposed to 5000 ppm; an effect was not found in virgin rats exposed at the same concentration. The onlyother maternal effect noted was mild alopecia in a few dims from the three tetrahydrofuran-exposed groups,which the researchers attributed to the irritant properties of the chemical. The only developmental effect in ratswas a significant redttction in fetal weight (mean or utt"r means) in the 5000 pp,n!.orp (to g2voof controlvalues)' Therefore, 1800 ppm was the NOAEL, and 5000 ppm was the LoAEL for both maternal anddevelopmental effects in rats in this study.
In the mice, groups of 30 mated and_ 1.0 virgin young adultfemale swiss (cD-l) mice were exposed to 0,600, 1800, or 5000 ppm (0, l77o,537o,or 14,750 mgtm'; Jrtetratrydrofuran vapors, 6 hours/day on GD 6-17.Pregnant mice were sacrificed on GD 18, and virgin mice were sacrificed the day after the last exposure.
Mortality was high among pregnant and virgin mice exposed to 5000 ppm (3}voafter 5 exposures).Survivors from this group were removed from treatment after "*poru." day 5 and held until scheduled sacrifice.Death was attributed to severe depression of the nervous system. Narcosis was observed in all mice exposed to5000 ppm and also some exposed to 1800 pp.. Jn addition, body weight gain was significantly reduced in boththe 1800 and 5000 ppm groups, possibly due to decreased uterine weight (associated with increased intrauterine

mortality).
Developmental effects included significant reductions in the number and percent of live fetusesflitter andsignificant increases in the number and/or percent of early resorptions per Iitter in bottr the 1800 and 5000 ppmgroups. In the 5000 ppm group, the 20 dams that survived the exposure period collectively produced onty'onelitter containing live fetuses. This study identified NOAELs of 1800 ppm for maternal toxiJity and 600 ppm fordevelopmental toxicity in mice.
The developmental toxicity of tetrahydrofuran in rats was also reported by Dupont (19g2). The studywas conducted in two parts. Initially, groups of seven (14 in control group) mated female Crl:CD rats wereexposed to 0, 200, 500, 2500 or 5000 ppm (0, 590,1475,7375, or tllso-mgm3; of tetrahydrofuran vapor for 6hours/day on GD 6-15. Subsequently, groups of 29 or more mated females i"r" "*por"d using the sameregimen to 0, 1000 or 5000 ppm (0, 295O, or 14,750 mg/m'). Dams were sacrificed on GD zt. BoAy weight,feed consumption, clinical signs, pregnancy rate, implantation, and fetal survival, growth, and morpholog| weremonitored. Results were combined for all data obtained after scheduled sacrifice,-b""urr" th" t*o partr of tfr.study were conducted identically and the data obtained were similar. During the exposure period, both maternalfood consumption and body weight gain were significantly reduced in the 5000 pprn grorp. Irthargy and ataxiawere also noted in these dams. Dams exposed to 2500 and 1000 ppm displayed-mild narcosis (reduced responseto noise stimulus). Developmental effects were limited to the 5000 ppm gro;p and included a significant
decrease in fetal weight and a significant increase in the incidence of fetuses with structural variations(unossified and partially ossified stemebrae). This study, therefore, identified a maternal NOAEL of 500 ppmand LOAEL of 1000 ppm, and a developmental NOAEL and LOAEL of 2500 and 5000 ppm, respectively.
No multigeneration reproduction studies were located.
Irritation Studies. ohashi et al. (1983) and Ikeoka et al. (1984) studied the effects oftetrahydrofuranvapor on the ciliary activity and morphology of the nasal and tracheal epithelia in rabbits. Adult rabbits wereexposed to concentrations ranging from 100 to 12,000 ppm (295 to 35,400 mgmr) for four hours. A controlgroup was not included. The animals were sacrificed immediately following i*po.u." and at intervals up tothree hours postexposure. Tetrahydrofuran appeared to decrease ciliary activityln both the nose and trachea in adose-related manner. In all dose groups, inhibition of ciliary activity *u. rn*i*ul immediately followingexposure and gradually diminished throughout the 3-hour recovery period. Morphological changes in themucosae were detectable by electron microscopy at concentrations of 1000 ppm and tigh"r.
Katahira et al. (1982) studied the irritating effects of tetrahydrofuran on the tracheal mucosa in rats.Groups of three male Sprague-Dawley rats were exposed to 0 (n=6), 100 or 5000 ppm (O,zgs or l4,75Omg/m3)of tetrahydrofuran for up to three weeks. Duration of the daily exposure period *ugot reported. one day]oneweek, and three weeks after beginning exposure, individual rats were ru"rifi""d and samples of their nasal andtracheal mucosa were obtained for study. ciliary beat frequency declined as exposure level and durationincreased. Light microscopy of the specimens revealed changei in the cilia and,disarrangement of theepithelial structures" after three weeks at 5000 ppm. Electron microscopy revealed similar findings.
Pharmacokinetics
$/rnn ", on Recycted paper
There is little information available on the pharmacokinetics of tetrahydrofuran. Absorption through thelungs in human volunteers ranged from 60-807a depending upon the breathin! rate and concentration oftetrahydrofuran (Kageyama, 1988; Teramoto et al., 1988).-Eitimates of oral absorption rates are not available.The urine concentration of videotape manufacturing workers at the end of their work shift was correlated (r=0'88) with exposure measured by personal sampling dosimetry (ong et al.,l99,l). The correlation betweendosimeter and the exhaled breath and blood concenirations 1r=o.ot and 0.6g, respectively) was lower. In aninhalation study in rats (Elovaara et al., 1984), there was a linear correlation between tetrahydrofuranconcentrations in air and those in brain and perirenal fat. As noted earlier, after two weeks, the body burdendecreased with exposure time, suggesting that oxidative metabolism of tetrahydrofuran may have been inducedby continued exposure. Increased 7-ethoxycoumarin o-deethylase activity was measured in the liver andkidneys.
The metabolic degradation pathways for tetrahydrofuran have not been elucidated (Moody, 1991). Fujitaand Suzuoki (1973) showed that tetrahydrofurfuryl mercaptan was metabolized to4-hydroxy-5-methylsulfonylvaleric acid by liver microsomes and cytosol. Also, incubation of tetrahydrofuranwith activated liver supernatant resulted in generation of formaldehyde, suggesting a mixed function oxidasereaction (Kawalek and Anders, 1980). However, the metabolites of tetrahyJ.r"ri', in biological systems havenot been fully elucidated (Moody, 1991). Following inhalation exposure, unmetabolized tetrahydrofuran waseliminated in the exhaled air and the urine (Kageyama, Iggg; ong et al., l99l).
DERIVATION OF A PROVISIONAL INHALATION RfC
A provisional RfC for tetrahydrofuran can be calculated based on liver effects in mice exposed totetrahydrofuran vapor for 13 weeks (chhabra et al., 1990; NTP, in preparation). The NoAEL for this effect was600 ppm (1770 mglm3) and the LOAEL was 1800 ppm (5310 mglm3)tasea on ttre o""urr"n." of hepaticcytomegaly and increased liver weight' The 600 ppm concentr*ion was considered a N9AEL despite increasedliver weight at this dose because the increase in lGr weight was slight and no histopathology was found.
, No non-neoplastic lesions were detected by histopathological examination of rats and mice in a chronic(105 week) exposure to 0, 200, 600, or 1800 ppm (0, 596, fi70,ir5310 mg/m3) tetrahydrofuran (NTp, inpreparation)' Thus, there was no indication that the centrilobular hepatocytomegaly observed in male andfemale mice during a l3-week exposure to 5000 ppm and in one ,nui" *our. atl aOo ppm occurred at lowerexposures during chronic exposure. organ weights, iematological parameters, ano blooa chemistry parameters,however, were not measured in the chronic study (NTP, in prelaration). Accordingly, the chronic exposurestudy provided no further delineation ofthe increased absolute and relative tiue, *Iiii,ts and decreased absoluteand relative thymus weights observed in male mice exposed to 600, 1800 and 5000 p"pm tetrahydrofuran for l3weeks or increased serum bile acids in high-dose female rats (chhabra et al., 1990; Nrp, in preparation).
It is possible that the liver changes identified in mice in this study could be consistent with an adaptive,rather than toxic, response to tetrahydrofuran. However, case reports of occupationally exposed workers(Garnier et al., 1989), acute studies in laboratory animals (Moody, 1gg1) and subchronic studies in rats(chhabra et al., 1990; Katahira et al., 1982) all found evidence oi u to*i" effect on the liver produced bytetrahydrofuran' Therefore, use of this endpoint was considered to be appropriate for derivation of a provisionalRfC.
Srrrraro, Becycted paper
Lurelt tvtorton - Mononl,vvHu
The NOAEL of 600 ppm based on liver effects in male mice is supported by the available database.Subchronic studies in rats had NOAELs of 1000 ppm (Katahira et al., f q8i) anA tdOO ppm (Chhabra et al.,1990). Studies of developmental toxicity showed that the developing fetus is not u rp"Lific target fortetrahydrofuran. Mast et al. (1992) determined NOAELs of 600 ppm for mice and t iOO ppm for rats for bothmaternal and developmental effects, while DuPont (1982) determined a NoAEL of 500 ppm for maternaleffects and a NoAEL of 2500 ppm for developmental effects in rats. Although tetrahydiofuran can be arespiratory irritant, local irritation was not identified as a critical effect in theiubchronic studies.
In calculating a human equivalent concentration (HEC) applicable to the observed NOAEL in mice, thehepatic effects produced by tetrahydrofuran in mice correspond to-an extrarespiratory effect produced by agas/vapor. Therefore, the NOAELTc is calculated as the product of the durat-ion_adjusted eiposure level(NoAELeor) and the blood:gas partition coefficient ratio in mice and humans (LoiL;). Because values for LH
and Ln are not available for tetrahydrofuran, the ratio is assumed to be 1 by default. The provisional RfC iscalculated as the NOAELTmc divided by an uncertainty factor of 1000 (10 ior use of a subchronic study, 3 forextrapolation from mice to humans using the dosimetric adjustments, 3 for database limitations including lackof a multigeneration reproduction study, and 10 for protection of sensitive individuals). The derivation is shownbelow:
NOAELADT = 1770 mglm3 x 6/24 x 517 = 316 mglm3
NOAELnBc = 316 mdm' xL,*[Lu= 316 mgm3 x I = 316 mgm3
Provisionar Rfc = NOAELHE./UF= 316 mgm3 / 1000 = 3E-r mgm3
For this provisional RfC, confidence in the key study is high. The study was well-designed, thoroughlydocumented, and carefully conducted. It included two different species and idintified a NOAEL and LOAEL'for each. A chronic Z-year inhalation study was also conducted. This study used an adequate number ofanimals of two different species and was carefully conducted; however, organ weight, hematology, and clinicalchemistry parameters were not measured. Although the database includes a well-documented NTp-sponsored
developmental toxicity study in two species, the database for this compound lacks reproduction data from amultigeneration study. Therefore, confidence in the database is medium. Medium confidence in the provisionalRfC follows.
Risk Characterization
The results of the 2-year chronic inhalation study showed that there was some evidence of carcinogenicactivity of tetrahydrofuran in male F344lN rats due to increased incidence of adenoma and carcinoma(combined) of the kidney (NTP, in preparation). There was no evidence of carcinogenic activityin femaleF344AI rats and male B6C3FI mice. There was clear evidence of carcinogenic aciivityin female B6C3F1 micedue to increased incidences of hepatocellular neoplasms. These responses, taken toget-her, were used as thebasis for a provisional weight-of-evidence classification for the compound's carcinolenicity, while theincidence of combined adenomas and carcinomas in mice have been used to derive carcinogenic slope factorsand unit risk values in a separate risk issue paper.

For non-cancer evaluations, the validity of the primary toxicological response(hepatocytomegaly) of male B6C3F1 mice to subchronic
"*poso.e to tetrahydrofuran to serve as a basis fordeveloping a chronic RfD and RfC for the compound depends upon the extent to which such areffi;;;;yeither (l) represent a precursor condition for the development of adenoma and/or carcinoma that became evidentin the 2-year inhalation study, or (2) represent a solely non-neoplastic response independent of tumor initiationand development. only in the second case would the response-be appticaule for developing quantitative toxicitybenchmarks such as the RfD and/or RfC.
In the Z-year study, other than a general statement that there was no evidence of non-neoplastichistopathological lesions in mice exposed to tetrahydrofuran for two years, no data were presented on theincidence of hepatocytomegaly in male or female B6C3F1 mice (NTi, in preparation). However, this broadstatement provides a strong implication of a potential etiological disconnect b"tru".n the histopathologicalresponse observed in the 13-week study and the incidence of combined adenomas/carcinomas in the livers of theanimals receiving tetrahydrofuran for two years.
Furthermore, the incidence of hepatocytomegaly in the l3-week study was observed primarily in the5000 ppm exposure group (Chhabra et al., 1990; NTP, in preparation). Minimal to mild centrilobularcytomegaly was observed in the livers of male (7110) and female (10/10) mice in the 5000 ppm group, and inone male mouse in the 1800 ppm group. The 5000 ppm concentration level was not employea in he 2-yearstudy, because this level induced ataxia in rats and sedation in both sexes of mice throujhout the "*porr."period' Treatment levels that result in significant increases in abnormal behavior may b-e considered to indicatethat an adequate high dose for carcinogenicity testing has been exceeded (U.S. EpA,'1996). The lg00 ppmtetrahydrofuran concentration also caused sedation in male mice in the l3-week study (Chhabra et al., i6eO;throughout the2-year inhalation exposure study (NTP, in preparation). Accordingty, trre incidence oftetrahydrofuran-induced hepatocytomegaly was limited to exposure concentrations that exceeded the maximumtolerated dose in long-term studies.
The hepatocyomegaly reported in mice in the l3-week study was characterized by an increased amountof cytoplasm and an increased size of some hepatocyte nuclei (Chhabra et al., 1990; NTp, in preparation).However, though increase in cell division would be anticipated in pre-neoplastic lesions, no increase in celldivision was indicated in the observations of hepatocytomigaly. The lack-of increased cell division implies thathepatocytomegaly is not a pre-neoplastic lesion.
Indirect inferences that illuminate this issue may be drawn from other NTp chronic toxicology andcarcinogenesis studies in which both endpoints were reported for the chronically-exposed animals. Forexample, in an NTP study in which B6C3FI mice were exposed to two pentachorophenol technical-grademixtures in feed for 2 years (NTP, 1989), the incidences of a range of non-neoplast^ic histopathologicalresponses were recorded, in addition to those of a comprehensive list of tumorigenic responses. Among the keycarcinogenic responses that served as a basis for the identification of the pentac-hlorophenot preparations ascarcinogens was the increased incidence of tumors of the adrenal gland medulla ana Lf combined adenomas andcarcinomas of the liver.

Two lines of evidence from these data allow a distinction to be drawn between the incidences of
hepatocytomegaly and liver tumor formation: (1) a (well recognized) and significant incidence of
adenoma./carcinoma formation was evident in control male mice in the complete absence of hepatocytomegaly,
and (2) pentachlorophenol-receiving animals displayed IOOVo incidence of hepatocytomegaly in circumstancei
where the incidence of tumors was considerably less. Taken together, tfrese RnAings point markedly to the
conclusion that the hepatocytomegalic response is likely to represent a true non-neopfustic lesion, divorced from
the tumorigenic response evident in the livers of male and female mice exposed for two years.
Accordingly, by analogy to the pentachlorophenol studies, the quantitative data on the onset of
hepatocytomegaly in response to subchronic exposure to tetrahydrofuran are considered to be appropriate for thedevelopment of non-cancer quantitative toxicity benchmarks such as the chronic RfD and RfC ;in; they areunlikely to represent a precursor condition for the tumorigenic responses evident in the livers of mice after twoyears exposure.

Draft Risk Assessment Issue Paper for:
Cancer Weight-of-Evidence, Slope Factor and Unit Risk for
Tetrahydrofuran (CASRI\ 109-99-9)
INTRODUCTION
No verified chronic RfD, RfC, or carcinogenicity assessment is available for tetrahydrofuran on IRIS
(U.S. EPA, 1997) or HEAST (U.S. EPA, 1995), and the U.S. EPA's CARA list (U.S. EpA, 1994) does not
indicate any other documents relating to THF. ACGIH (1992,1996) has adopted a TLV-TWA of 200 ppm (590
mg/m3) and a STEL of 250 ppm (737 mg/m') to protect workers against upper respiratory tract irritation and
systemic effects (including narcosis) produced by tetrahydrofuran. OSHA has established a PEL-TWA for
tetrahydrofuran of 200 ppm (OSHA, 1993). The NIOSH REL-TWA is 200 ppm and the STEL is 250 ppm
(MOSH, 1992).
To identify research papers pertinent to the carcinogenicity of tetrahydrofuran, computer searches of the
literature were conducted from the HSDB, RTECS, TSCATS, MEDLINE, and TOXLINE (and its subfiles)
databases, covering the time period of 1992-1997. The literature search was conducted in September 1997.
REVIEW OF PERTINENT LITBRATURE
Tetrahydrofuran, a four-carbon ether, is widely used as an industrial solvent, primarily in the dissolution
of plastic resins, such as polyvinyl chloride and vinylidene chloride co-polymers, and as a reaction medium.
The combined effects of its volatility and extensive use by industry creates a significant potential for
occupational exposure to tetrahydrofuran through inhalation.
There is little information available on the pharmacokinetics of tetrahydrofuran. Absorption through the
lungs in human volunteers ranged from 60-807o depending upon the breathing rate and concentration of
tetrahydrofuran (Kageyama, 1988; Teramoto et al., 1988). Estimates of oral absorption rates are not available.
The urine concentration of videotape manufacturing workers at the end of their work shift was correlated (r=
0.88) with exposure measured by personal sampling dosimetry (Ong et al., l99l). The correlation between
dosimetry and the exhaled breath and blood concentrations (r=0.61 and 0.68, respectively) was lower. In rats,
there was a linear correlation between tetrahydrofuran concentration in air and brain and perirenal fat
tetrahydrofuran concentrations in an inhalation study (Elovaara et al., 1984). After two weeks, the body burden
decreased with exposure time, suggesting that oxidative metabolism of tetrahydrofuran may have been induced
by continued exposure. Increased 7-ethoxycoumarin O-deethylase activity was measured in the liver and
kidneys. Following inhalation exposure, unmetabolized tetrahydrofuran was eliminated in the exhaled air and
the urine (Kageyama, 1988; Ong et al., 1991).
The metabolites of tetrahydrofuran in biological systems have not been fully elucidated (Moody, 1991).
Fujita and Suzuoki (1973) showed that tetrahydrofurfuryl mercaptan was metabolized to
4-hydroxy-5-methylsulfonylvaleric acid by liver microsomes and cytosol, but it has not been established that
similar metabolism occurs with free tetrahydrofuran. Incubation of tetrahydrofuran with activated liver
supernatant resulted in generation of formaldehyde, suggesting a mixed function oxidase reaction (Kawalek and
'Prlnted on Becycled Papet
Anders, 1980). If a carbon atom adjacent to the oxygen atom in the ring is hydroxylated, the product would bey-butyrolactone, which possesses convulsive properties (Elovaara et at., tgg+); however, this metabolicconversion has not been demonstrated.
Human Carcinogenicity Data
No epidemiological studies on the carcinogenic effects of tetrahydrofuran in humans were available.
Animal Carcinogenicity Data
Chronic inhalation study. AZ'year chronic inhalation exposure study using male and female F344 ,1rats and B6C3F1 mice has been conducted under the sponsorship of the National Toiicology program (NTp, inpreparation). No other chronic exposure studies were found.
The overall purity of the tetrahydrofuran used was determined to be approximately 99vo, and theperoxide concentration no greater than 3 ppm. A rotary evaporator system was used to generate tetrahydrofuranvapor' A stabilizer, 2,6-di'tert-butyl4-methylphenol @Frt), was added to all lots of tetrahydrofuran by themanufacturer. Because BHT is less volatile than tetrahydrofuran, the BHT was retained in the rotaryevaporation system. The-terrahydrofuran generator reservoir and the exposure chamber atmosphere weremonitored for stability, BHT, peroxides, and contaminants.
Groups of 50 male and female F344/}{ rats and B6C3FI mice were exposed to 0, 200, 600, or I g00 ppm(0' 590, 1770, or 5310 mg/m3) tetrahydrofuran by inhalation, 6 hours/day, 5 days/week for 105 weeks. Allanimals were observed twice daily. Clinical findings and body weights were recorded weekly for l2weeks(rats) or 13 weeks (mice), monthly through week 91 (rats) or weeki2(mice), and every two weeks until the endof the study' Complete necropsies and histopathological examinations of a wide range of tissues and organswere performed on all rats and mice. However, organ weights were not measured, and, as blood samples werenot collected, hematological and clinical chemistry analysis were not performed. Animals found dead due toaccidents were censored from the survival analyses, but animals dying from natural causes were included. Thedata were subjected to rigorous statistical analysis by standard procedures.
Rat study. Estimates of Z-year survival probabilities and Kaplan-Meier survival curves indicated thatsurvival of male and female rats exposed to tetrahydrofuran was similar to that of chamber controls. Survival offemale rats to the final sacrifice was approximately 5ovo,but survival of males varied from l0 to z4vo.Although survival of male rats to the final sacrifice in chamber controls was higher than in the tetrahydrofuranexposed groups, survival at?5 weeks was greater thangOvo in all groups and the differences among groupsemerged only after 100 weeks. Thus, tetrahydrofuran exposure oid noi significantly reduce the survival of ratsof either sex' Mean body weights were similar to chamblr controls throughout the study. No clinical findingsrelated to tetrahydrofuran exposure were found, and no non-neoplastic lesions were found in either male orfemale rats at concentrations up to 1,800 ppm tetrahydrofurun uft", 105 weeks of exposure.
The incidences of renal tubule epithelial adenoma were marginally increased in 600 and l g00 ppm
@rrnr"o or r"cycted paper
receiving-males, however, the incidences were not statistically greater than in controls. Also, two males in the1800 ppm group had renal tubule epithelial carcinomas. The combined incidence of adenomas and carcinomasexceeded the historical range for chamber controls and displayed a dose-related trend (control, 1/50; 200 ppm,1/50; 600 ppm, 4150; 1800 ppm 5/50). The increased combined incidence of renal tubular neoplasm wasconsidered to be chemical-related by the authors for two reasons. First, spontaneous renal ,"oplur,,, ur"relatively uncommon (historical background incidence was less than lzoinZ-yearNTp studies). Second therewas a lack of chemical-related increase in the incidence or severity of age-related degenerative renal disease inthis study. Renal tubule neoplasms were not observed in female rats.
The incidence of fibroadenoma in mammary glands of female rats exposed to 600 or l g00 ppm
tetrahydrofuran was slightly higher than those of chamber controls (23150, zitso, zgt50,3lt5o). Thi trend wasmarginally significant (p=0.031), but the pairwise comparisons were not. There was no evidence of an increasein malignant neoplasms. Male rats exposed to 1800 ppm had a slightly greater, though not statistically
significant, incidence of fibroadenoma. Neither marginal increase in mammary glanl neoplasms wasconsidered by the authors to be chemically related.
The incidence of testicular adenoma was increased in rats exposed to tetrahydrofuran in comparison toconcurrent chamber controls, and the difference was statistically significant in the iSOO pp, group (23150,3ll50, 31150,34150). The incidence in the 1800 ppm group, however, did not exceed the mean incidence ofhistorical controls in NTP inhalation studies (68.7vo;range 54-837o). Thus, the investigators speculated that theapparent increase in testicular adenomas in the tetrahydrofuran exposed groups may have been due to anunusually low incidence in the concurrent controls.
Mouse study. After 36 weeks, the survival of male mice exposed to 1800 ppm was significantly lowerthan that of the chamber controls, with the average life span reduced from 689 Oayi ior controis to 456 days.Survival of males in the 200 and 600 ppm groups and of females in all exposur" g.oup, was similar to thechamber controls. Mean body weights of male and female mice were similar to those of the chamber controlsthroughout the study. No clinical findings related to exposure to tetrahydrofuran were observed in female mice.However, males exposed to 1800 ppm were observed in an state of nariosis during exposure and up to one hourafterward. The mice were limp, with their feet hanging through the cage floor, ani thi preputial fui was wetwith urine. At the time the exposure concentrations for the 2-year study were selected, it *u, predicted that anincrease in tolerance to the sedative properties of tetrahydrofuran observed during a subchronic study mightresult in complete tolerance. This prediction was clearly incorrect, and26 of the male mice in tfre ttOO ipmgroup died during the first year of exposure.
Male mice exposed to 1800 ppm tetrahydrofuran had significantly greater incidences of nonneoplasticlesions of the urogenital tract than chamber controls. These lesions (which occurred primarily among 26animals that died during the first year of the study) included suppurative inflammation of tne tiOney,-urinarybladder, prostate gland, and preputial skin; hydronephrosis of the kidney; and transitional epithetjhyperplasiaof the urinary bladder. The inflammatory urogenital tract lesions were considered to be the most likeiy cause ofthe lower survival rate observed in this exposure group. The authors speculated that prolonged wetting of thepreputial fur during exposure-related narcosis may have predisposed these animals toa preputial bacterialinfection which subsequently ascended the urogenital tract resulting in moribundity and ultimately death.Increased incidences of hyperplasia of the bone marrow, hematopoietic cell proliferation of the spleen, and
@rnn "o o, Becycted paper
thymic atrophy also were observed in the 1800 ppm exposed male mice. The authors considered these changesto be secondary reactive responses to acute inflammation of the urinary and urogenital tracts that were ofmarginal significance.
The incidence of hepatocellular neoplasms (adenoma plus carcinoma) in female mice in the 1g00 ppmgroup was significantly increased relative to chamber controli (17150,24/50,26150, 41t4g)and exceeded thehistorical range for chamber controls in Z-year NTP inhalation studies. The incidence of multiplehepatocellular neoplasms was also increasid in the 1800 ppm female group (4/50, 7/50,6150,1g/4s). Althoughthe increases in incidence in the 200 and 600 ppm female g.oup, were not statistically significant, they diddisplay a positive trend' By contrast, the incidences of combinld hepatocellular neop'lasms in male mice werenot significantly increased from chamber controls (35/50, 31150,30/50, l g/50). The apparent decrease inincidence in the 1800 ppm group was a result of the deaths of 26 males during the first year of the study.
The results of the 2-year chronic inhalation study showed that there was some evidence of carcinogenicactivity of tetrahydrofuran in male F344arl rats due to increased incidence of adenoma and carcinoma(combined) of the kidney. There was no evidence of carcinogenic activityin female F344aI rats and maleB6C3F1 mice' There was clear evidence of carcinigenic aciivityin female B6c3Fl mice due to increasedincidences of hepatocellular neoplasms.
Supporting Evidence
Genotoxicity' Tetrahydrofuran has been tested in a variety of mutagenicity assays, and the results were,with one exception, negative. Tetrahydrofuran was negative in salmonella typhimuriuz strains TAgg, TAl00,TAl535' and rA1537 with or without Arochlor-induced rat or hamster 59 (Mortelmans et al., l9g6). It did notinduce sister-chromatid exchanges or chromosomal aberrations in cultured chinese hamster ovary cells with orwithout 59 (Galloway et al., 1987). No induction of sex-linked recessive lethal mutations was noted in maleDrosophila melanogaster (Valencia et al., l9g5).
Results of the mouse bone marrow sister-chromatid exchange assay were negative. It did not inducechromosomal aberrations in mouse bone marrow cells (NTP, in preparation). Althoigh results from the initial24-hour sister-chomatid exchange test were positive, the repeat test gave negative results and the 42-hour testwas also negative' The frequencies of micronucleated erythrocyes in peripheral blood from male and femalemice were determined at the end of a l3-week subchronic "*poru.". Neittrer polychromatic nornormochromatic erythrocytes in either male or female mice was significantly incieased. Tetrahydrofurantreatment of rats invivo did not induce unschedured DNA synthesis in hepaiocytes (Mirsaris et al., r9g3).
structural Analogue Data. Another cyclic ether solvent, 1,4-dioxane, was found to be carcinogenic byoral exposure (u's' EPA, 1997). It induced an increased incidence of malignant tumors in the liver and nasalcavity in rats, and it induced tumors of the liver and gall bladder in guinea figs. tnere was no evidence ofcarcinogenicity in one inhalation study with 1,4-dioxane. Based on these ririi"., the u.S. EpA (lgg7) hasclassified l '4-dioxane as a probable human carcinogen with a weight-of-evidence classification of 82 (indicatessufficient evidence in animals and inadequate or no evidence in humans). The slope factor derived for1,4-dioxane was l. rE-2 (mg/kg-day)-' and the unit risk was 3.lE-7 (tte/L)" .

WEIGHT.OF.EVIDENCE CLASSIFICATION
1986 Guidelines: weight'of-Evidence classification. The2-yearNTp study on the carcinogenicity ofinhaled tetrahydrofuran (NTP, in preparation) observed some evidence of carcinogenic activityin male F344lNrats due to increased incidences of combined adenoma and carcinoma in the kidnJy, and clear evidence ofcarcinogenic activity in female B6c3Fl mice due to increased incidences of combined adenoma or carcinomain the liver' However, since this appears to be the only study available that demonstrates tetrahydrofuran-relatedincidence of neoplasms, a weight-of-evidence carcinogeniciiy classification of ,,C',,
11 possible humancarcinogen due to inadequate evidence in human beings and iimited evidence in animals, is appropriate.
1996 Proposed Guidelines: Weight'of-Evidence classification. Tetrahydrofuran is tikelyto be ahuman carcinogen by any route of exposure. The weight-of -evidence for human tarcinogenicity is based on a2-year inhalation exposure study that showed clear ev-idence of carcinogenic activity of tetrahydrofuran infemale B6c3Fl mice due to increased incidences of hepatoceilular neoplasms.
In comparison with other agents designated as likely carcinogens, the overall weight-of-evidence fortetrahydrofuran places it at the low end of the grouping. This is because there is no human evidence ofcarcinogenicity, and there was no evidence of carcinogenicity in female F344lt{ rats or in male B6c3Fl mice inthe 2-year inhalation study. The human relevance of the animal evidence of carcinogenicity relies on a defaultassumption of relevance.
There is little information on the mode of action for the carcinogenicity of tetrahydrofuran.Tetrahydrofuran showed little evidence of mutagenic activity in a variety of ii vivo and invirro assays. In theabsence of mutagenic activity, the mode of action of tetrahydrofuran may be due to promotion of spontaneouslyoccurring cell transformation events' Thus, tetrahydrofuru, .uy be acting as an epigenic carcinogen. Thestep-wise increase in hepatic tumor incidence in female B6c3Fi mice wilh irc."usii'g Jose, however, appears tobe close to linearity. Thus, a linearized curve-fitting extrapolation model for quantita:tive risk estimation may bethe most appropriate choice. It is recogaized that this appioach may overestimate risk at low doses.
Uncertainties arise from the background incidence of liver cancer in the B6c3F1 mouse. The highbackground incidence of liver tumors in male controls (loEo)is consistent with the historical incidence rate forthis response' This rate would likely invalidate the use of the incidence of liver tumors in males as a model forpotential human carcinogenic responses. Also, the background incidence in females in the subject study, thoughlower than in males (34vo in this study versus a historical background of 23vo),may also serve to diminishconfidence in quantitative derivations of risk estimates based o-n these data. Historical data are, however, oflimited value, because several factors that may have varied between the historical studies and the current studysuch as; animal room environment, dietary faclors, body weight, gross necropsy procedures, slide preparationprocedures, and histopathological diagnosis criteria have all ieen"shown to inRuence background tumorincidence (Haseman' 1995). Thus, the concurrent controls are the most valid for determining whether increasedtumor incidences are meaningful. Historical control data can be used to discount a statistically significantincrease in tumor incidence if it can be shown the incidences in the dose groups are consistent with controlvalues from similar past experiments (Haseman, 1995). In this study. however, the incidences in the treatment
@rr,nrro o, Becycted paper
groups all exceed the range of historical control data. Thus, the liver tumor incidences in the tetrahydrofuran
exposed female B6C3FI mice provide a valid basis for derivation of carcinogenic slope factors and unit risks.
DERIVATION OF ORAL SLOPE FACTOR AND INHALATION UNIT RISK
Although the increased incidence of renal tumors in male F344/Ir{ rats receiving tetrahydrofuran was
considered to be chemical-related, even at the highest dose the incidence only reached 107o. This was not
statistically greater than the concurrent control incidence. Also, the occurrence of chemically induced renal
neoplasia has been shown to be associated with the accumulation of the alpha-2p-globulin protein which does
not occur in humans. Thus, male rat kidney neoplasia is not considered to be relevant to assessing human
carcinogenicity risk ru.S. EPA l99l).
The step-wise increase in hepatic tumor incidence of female B6C3FI mice (to 85Vo) withincreasing
dose in this animal model lends weight to the conclusion that an association exists between the carcinogenic
response and the challenge with tetrahydrofuran. That the carcinogenic response to tetrahydrofuran appears to
be close to linearity suggests that a linearized curve-fitting extrapolation model for quantitative risk eiiimation
may be the most appropriate choice.
The extrarespiratory responses to tetrahydrofuran observed in B6C3FI mice provide the rationale for
using inhalation data to derive an oral slope factor and unit risk from these data in addition to those for
inhalation exposure. The calculation of oral and inhalation doses (mglkg-day) from the concentrations of
tetrahydrofuran in air are shown in Table l. As noted in the footnotes to Table 1, default parameters employed
in these transformations were inhalation absorption factor = 1, body weight (mouse) = 35.3 g, body weigtrt
(human) = 70 kB, inhalation rate (mouse) = 0.06 m3/day, and inhalation rate (human) =20 m3/day. Thehouse
values are default values for female B6C3F1 mice in a chronic study (U.S. EPA, 1988). These dose values were
used to calculate oral and inhalation slope factors and unit risk values for extra risk using the linearized
multistage model Global 86 (Tables 2 and3).
ORAL:Unit Risk =2.28-7 (trg/L)-,
Slope Factor = 7.68-3 (mg/kg-day)''
INHALATION: Unit Risk = 1.gE-6 (pgmr)-'
Slope Factor = 6.88-3 (mglkg-day)'
Confidence in the derivations. The primary source of uncertainty surrounding the derivation of
carcinogenic slope factors and unit risks centers on the appropriateness of applying curve fitting methodologies
to the origin (mandated) for data where the background incidence rate for the response is high lllUoy f6e-
utility of deriving risk estimates at hypothetical low doses in humans from animal data wheie the background
incidence rate for an effect is as high as 34%o (the report suggests a historic background rate of 23Vo for these
responses in female B6C3FI mice), may be open to question since an extrapolation method will show
'Prlnted on Recycled Paper
considerable divergence from the experimental dose-response curve (incidence) at the two extremes of therange. Where the slope of the extrapolated lower 95Vo confidence limits on (human equivalent) dose may differsubstantially from the experimental dose-response characteristics (in mice), the justification for applying themouse data to derive provisional carcinogenic slope factors and unit risks in human beings resideiln theperceived balance between, (1) the likely difference in susceptibility of human beings to spontaneous livertumor formation compared with that of female B6C3FI mice, (2) the implications o1this difference for theapplicability to human health of the clear-cut dose-dependent increase in the incidence of liver tumors in femaleB6c3Fl mice, and (3) the extent to which the derived carcinogenic slope factors and unit risks provide relevantinsights into the quantitative human health impacts of tetrahydrofuran where the suitability of the animalmodel/carcinogenic response combination may be only marginal. However, in view of the uncertainties
surrounding the appropriateness of the low-dose extrapolation approach for dak displaying high backgroundincidence of tumor formation, the confidence in these derivations is rated as low.

Comment: MW-19, 1 1/30/00: pump intially placed into well at a depth of 1 1 0 ft, and well purged. After many gallons of purging, the
groundwater became turbid. Pump was lowered to 120 ft and later to 140 ft in an attempt to get clear groundwater. After
removal of 100 gal, purging ceased. Then sampling crew returned the next day,12l1l0O, purged 1 galand then collected
samples.

Comment: Manganese (Mn) GWAS: is based on EPA DW draft Health Advisary Reference Dose (RfD), RfD = 0.14 mg/kg/day for
the consumption of food and water (see summary entitled "Drinking Water Regulations and Health Advisories", October,
1996, EPA Office of Water, EPA822-8-96-002, p. 8). For a 70-kg adult, the RfD can be expressed as: 0.14 mg/kg/day.
70 kg = 9.8 mg/day Mn (see 1211196 EPA lRlS database printout on Manganese, p. 4). Now to convert the RfD to a
health advisory, do as follows:
(RfD - 5 mg/day) I (3- 2literlday intake) = 0.8 mg/|, where:
5 mg/day = National Research Council's "estimated safe and adequate daily dietary intake" for manganese (ESADDI),
and
Factor of 3 = to protect infants
(see 1/3/00 EPA Region 8 letter from Bob Benson (toxicologist) to Loren Morton Utah DEQ/DRC, and 1211196 EPA lRlS
database printout on Manganese, pp. 3-5).
Note that this concentration, 0.8 mg/|, is GREATER than the EPA secondary DW MCL of 0.05 mg/|, which was set
primarily on the fact that manganese concentrations above this value tend to stain laundry (personal communication, Mr.
Bob Benson, EPA Region 8 DW toxicologist).
Previously the State's Ad Hoc GWQS for manganse was proposed at 0.04 mg/|, based on a former RfD value and
calculations by EPA Region 8 toxicologist, Bob Benson (personal communicalion,2llTlg5). However, the ingestion RfD
was revised in the EPA lRlS database on 1111195. Thus it was necessary to now update the State's Ad Hoc GWQS.

Effects Assessment Summary Tables, 3rd Qtr., FY1989, Office of Emergency and Remedial Response, Washington DC,
64pp). This is a moderate value in that both lower and higher RfD values can be found for vanadium compounds in the
literature, as follows: 1) Vanadium sulfate, VSO4, RfD = 20 ug/kg/day (ibid.), and 2) Sodium vanadate, NaVO3,
lntermediate Minimal Risk Level (equivalent to EPA RfD) = 3 ug/kg/day (see Agency for Toxic Substances & Disease
Registry).
To convert to an adhoc health advisory, calculate as follows: 9 ug/kg/day " 1 dayl2liters . 70 kg adult * 0.2 = 0.063 mg/|,
round down to 0.06 (0.2 factor = drinking water Relative Source Contribution, personal communication, Bob Benson,

Regulations and Health Advisories", December, 1993, Office of Water. Lifetime health advisory expressed simply as
ammonia (30 mg/l). This health advisory adusted to ammonia (as N) values would be lower, as follows:
1) Atomic Weight for NH3:
N=14.0067*1=14.0067
H=1.0079*3=3.0237
NH3 = 17.0304
2) Now Ratio N / NH3 = 14.0067 I 17.0304 = O.8225
3) Now convert NH3 health advisory to NH3 (as N): 30 mg/l . 0.8225 = 24.67 mg/|, round up to 25 mg/|.
Cell: F44
Comment: NH3 (as N) Calculated as follows:
NH3 * Atomic Weight N / Atomic Weight NH3, where:
Atomic Weight of N = 14.0067,
Atomic Weight of NH3 = 14.0067 + 3(1.0079) = 17.0304.

From: Harold Roberts <[e-mail]>To: 'Loren Morton'<[e-mail]>Date: 9l30l02 3:49PMSubject: RE: Missing Groundwater Quality lnformation - November/December, 2000
Split Sampling Event
Loren:
ln response to your e-mail of Friday afternoon, I have done some additional
research on the remaining outstanding issues with respect to the Nov/Dec.
2000 Split sampling data. Hopefully we can put this issue to rest and move
on to the 2001 sampling data.
1) After our phone conversation I faxed pages 3 thru 14 of Energy Labs
Reference No. 38456R. My records indicate this information was a part of
the September 6th transmittal to your office, but never the less you now
have that information for your records. Metals results are missing for
MW-11, MW-15 and TW4-5. Please see the attached revised summary matrix
detailing the specifics of missing data.
2) Generalchemistry analysis is missing for MW-15 and TW4-4. My earlier
summary matrix had erroneously indicated missing data for MW-4, when it
should have been TW 4-4. Pages 18 - 21 of ELI Reference No. contains chain
of custody information rather that these missing analytical data. Please
let me know if you need the chain of custody information.
3) Radiological analysis is missing for TW4-1 ,TW4-4 and TW4-6.
After talking with Wally Brice at the White Mesa Mill, he confirmed that
prior to shipping the samples from the 2000 split sampling, several bottles
were lost due to breakage from freezing. Unfortunately our records are
incomplete as to which specific samples were lost, but we can assume this
is the explanation for the missing data. I apologize for any confusion
this has caused.

Harold,
I appreciate the additional groundwater quality data you provided me from
the November/December, 2000 DRC/lUC split groundwater sampling event, which
was attached to your 916102 cover letter. As you recall, this submittal
was in response to a 8/30/02 email I wrote to Michelle Rehmann, see
attachment. I have reviewed the additional IUC sampling information and
1 Loren Morton - RE: Missing Groundwatel
found that a number of laboratory reports continue to be missing, as
follows:
1. Heavy Metals Results: lab repofis continue to be missing for the same
14 wells, including: MW-1, MW-2, MW-3, MW-4, MW-11*, MW-15*, MW-17, MW-18,
MW-19, TW4-2, TW4-3, TW4-5., TW4-7, and TW4-8.
2. General Chemistry Parameters (major ions, TDS, etc.) - lab reports are
still missing for 2 wells, including: MW-15* and TW4-4.
3. Radiologic Parameters - lab reports are missing for 3 wells at the
facility, including: TW4-1", TW4-4*, and TW4-6".
* = lab reports identified by IUC as not available (see summary matrix in
916102lUC submittal).
Review of your 916102 sample summary matrix indicates that 11 of the 14
missing reports had already been submitted to the DRC. We have double
checked the original 10126101 IUC submittal and continue with our finding
that these 14 lab reports are missing. From our discussion this morning,
it appears that some of these samples may be found in Energy Laboratories
lnc (ELl) data package number 38456R, which was not included in the
original submittal. Your 916102 summary table indicates that this data
package contains 12 sample results (pp. 3 -14). Please provide this data
at your earliest convenience.
The916102lUC sample summary matrix also indicates that 3 of the 14
missing heavy metal reports are unavailable, as noted above with an
asterisk. Please explain how and why these heavy metal results came to be
lost or made unavailable.
For the generalchemistry parameters, two lab reports from the
November/December, 2000 split sampling event continue to be missing, as
outlined above. The 916102lUC summary matrix indicates that the TW4-4
report was already provided in the 10/26101 submittal. Again, we have
revisited that submittal and continue with our previous finding. From our
discussion this morning, it appears that ELI data package number 38435R
contains general chemistry results. Some of this data package was provided
in the original submittal. Unfortunately, pages 18 - 21 of this data
package continue to be missing. Perhaps these missing pages contain the
generalchemistry results for wellTW4-4. Please provide these lab results
at your earliest convenience.
The916102lUC summary matrix indicates that the generalchemistry report
for MW-15 is unavailable, as noted above with an asterisk. Please explain
how and why this general chemistry report came to be lost or unavailable.
With regards to the radiologic parameters, lhe 916102lUC summary matrix
indicates that allthree of these lab results are unavailable. Please
explain how and why these reports were lost or made unavailable.
Thanks again for your help in completing our data set and resolving these
issues. A written response would be appreciated. lf you have any
questions or concerns, please call me.

IUC: Missing Groundwater Quality lnformation - November/December, 2000 Split
Sampling Event
Michelle,
ln preparation for the next split sampling event, scheduled for the week of September 9, I have been
reviewing the results you provided for the November/December, 2000 split sampling event (submitted with
a transmittal letter of October 26,2001). During this review I found that a number of well results are
missing from the October 26,2001 submittal, as follows:
'1. Heavy Metals Results: lab reports are missing for 14 wells, including: MW-1 thru MW-4, MW-11,
MW-15, MW-17 thru MW-19,TW4-2, TW4-3, TW4-5, TW4-7, and TW4-8.
2. General Chemistry Parameters (major ions, TDS, etc.): lab reports are missing for 15 wells, including:
MW-1 thru MW-4, MW-15, MW-17 thru MW-19, TW4-1 ,TW4-2,TW4-4, and TW4-6 thru TW4-9.
3. Radiologic Parameters (gross alpha, gross beta, uranium): lab reports are missing for all21 wells at
the facility, including the 12 "MW" series wells and the 9 "TW4" series wells.
Could you please complete our records by submitting the missing lab reports?
Also, my records show that we have not exchanged groundwater quality data from the November, 2001
split sampling event. We will mail you our results on Tuesday or Wednesday of next week. When may
we expect your results?
Dave Frydenlund called this week regarding the numbers and types of parameters DRC plans to sample
for during the upcoming event. Bill Sinclair provided Dave some general information yesterday in this
regard. Early next week I willemailyou a detailed listing of the parameters we will analyze for in each
individualwell. I will also add the target MDL values needed for each parameter.
Also, can you tell us when Ron Berg will begin his sampling on Monday, September 9? lf needed, we can
be in Blanding ready to go at 8:00 am that morning.
Thanks for your help with this missing data. I will be in touch next week.

Re: Transmittal of IUSA's Field Notes and Analytical Results from November/December
2000 Groundwater Split Sampling at the White Mesa Uranium Mill, Blanding Utah
Dear Mr. Sinclair:
As discussed during our meeting on October 5,2001, enclosed are the results from the groundwater
split sampling performed during November-December of 2000 at the White Mesa Mill near
Blanding, Utah. This transmifial includes both the field notes prepared during the sampling event
and the certified laboratory's analytical data reports.
Review of the results indicates no significant variations or deviations from historic data. There were
two anomalies identified, which are discussed below.
Apart from samples collected from the Chloroform Investigation (TW-) wells, only one
sample collected from a Monitoring Well (MW-), that from MW-I7, was reported to contain
chloroform. A review of the field notes and discussion with Mill sampling personnel
revealed that the well in question, MW-I7, was purged and sampled immediately after MW-
4. At the time of the November-December split-sampling event, MW-4 contained the
highest levels of chloroform detected in any of the Chloroform Investigation wells.
Therefore, the very low detection of chloroform in MW-17 (3.79 ppb) appeared suspect, and
was considered likely due to cross-contamination. During the November/December split-
sampling event, the well sampling order was slightly modified, with the intent being to
optimize field time for State participants.
IUSA resampled and reanalyzed water from MW-17 for chloroform during the quarterly
(March 2001) sampling event, collecting the MW-17 sample before any of the TWs or MW-
4had been sampled. The analyical result for an equipment rinsate taken on March 23,2001,
and prior to purging and sampling of POC wells, resulted in a chloroform result of 16.7 ppb.
The sampling equipment was thoroughly cleaned before it was used at MW-17. The
equipment rinsate taken before sampling MW-l7 yielded a result of N.D. at 1 ppb. The
t.
2.
sample from MW-17 also yielded N.D. at I ppb. These results are consistent with the
hypothesis stated above under (1.), namely that the previous chloroform detection in MW-17
was most likely due to cross contamination from the equipment. To ensure the quality of
data, IUSA sampling personnel have concurred that in the future, they will sample all of the
POC wells before sampling any Chloroform Investigation wells. This ordering is important
to avoid potential cross-contamination of our NRC-required POC wells, or any other wells
used in split sampling at the Mill, with chloroform from the Chloroform Investigation wells.
A very small concentration of toluene was reported for two sample vials submitted for
Chloroform Investigation temporary well TW4-4. The results, I .17 and 1 . l0 ppb, are the
only toluene reported for any of the samples collected from any of the wells during the
sampling event, and are the only known reports of toluene in any water samples collected at
any time at the Mill. Based on discussions with the Certified Laboratory, Energy
Laboratories, Inc., it is IUSA's understanding that toluene is often found as a result of
sampling contamination; indeed, it is possible that this may have produced the result in
TW4-4. IUSA will again analyze for toluene at this and all other wells used in the next split
sampling event, and will also use other quality assurance field measures to evaluate and
reduce the potential for toluene contamination of samples collected for analysis under
Standard Method 8260.
If you have any questions regarding these results,I can be reached at 303.389.4131.

IUC: Yesterday's Questions on 11/00 DRC Split Sampling Results
Bill Sinclair let me know that we will work with you on a sampling plan for the tailings pond wastewater
sampling issue - before we collect any new samples. He also said there was some additional historic
wastewater quality data that IUC will provide. That will be helpful in my review of the 9/25101 HGC report.
About your questions regarding tetrahydrofuran and sulfur dioxide, I contacted Jack Oman the analyst at
the State Health Laboratory (SHL). He provided the following information:
1. Tetrahydrofuran (THF) - I need to correct statements I may have made previously. THF found in the
5/99 split samples was reported as a Tentatively ldentified Compound (TlC), because at the time SHL had
no calibration standard. However, for the 11/00 event, SHL used a THF calibration standard. This is the
reason why the 1 'll00 THF results for MW-1, MW-3, and MW-12 were not flagged "TIC". For those most
recent samples, Mr. Oman also reports:
1) a 2-point THF calibration curve was used in analysis of the 11/00 samples.
2) the samples were diluted during the analysis to ensure the measured concentration was inside the
range of THF calibration curve.
3) this technique is compliant with the EPA 82608 method.
Consequently, we have concluded that the SHL THF results are valid for the 11/00 samples. As for why
the THF results are hand-written on the lab report sheet, Jack explained that this is due to a software
limitation of the SHL database that tracks sample results. Apparently, SHL is in the process of fixing this
database software limitation.
As for analysis of THF in next week's sampling event, SHL will use a S-point THF calibration curve that will
simplify the analysis. This approach is also compliant with the EPA 82608 method.
2. Sulfur Dioxide (SO2) - Mr. Oman agrees with you that this is a volatile non-organic compound.
However, it was reported as a TIC compound on the 11/00 sampling results for well TW4-9 due to its
large peak on the SHL GC/MS spectrum, and a lack of a SHL SO2 calibration standard. Currently, we are
not planning on securing a SO2 standard for quantitative purposes. However, if this peak continues to be
observed in TW4-9, or in any other well, we will work to find a standard in order to properly quantify it.
By way of information, there are several possible occurrences of SO2 in the environment, including (see
Nebergall, Schmidt, and Holtzclaw, 1 976, General Chemistry, p. 576-578):
lndustrialcombustion of coal or oil
Small quantities can be formed in combustion of gasoline (f rom sulfur compounds in gasoline),
Burning of free sulfur.
Roasting of certain sulfide ores (e.9., ZnS, FeS2, and Cu2S)
As an ingredient in the production of sulfuric acid.
Reaction of reducing agents with hot concentrated sulfuric acid (e.9., carbon, copper, sulfur)
Since sulfuric acid has been used in extremely large quantities at the White Mesa facility, we will continue
to watch for SO2 concentrations in groundwater. Should this contaminant appear again as a TIC
compound, we will attempt to properly quantify such concentrations in future sampling.
I have also heard from our sampling staff at the Division of Water Quality. They have been in contact with
your staff at the mill and are prepared to begin the split sampling first thing Monday morning, November 5.
Thanks for your help in putting together this split sampling event.

IUC Request for Copies of DRC Groundwater Quality Results: November, 2000 White Mesa
Uranium Mill Split Sampling Event.
Dear Ms. Rehmann:
The puqpose of this letter is to respond to your October 5, 2001 request for copies of the Division
of Radiation Control (DRC) results from our split groundwater sampling event conducted at the IUC
White Mesa uranium mill between Novembe r 27 and December 1 , 2000 (hereafter November, 2000
Event). The DRC sample results you requested, have been grouped into two (2) categories of
information, including (see attached results from the Utah State Health Laboratory):
1) General inorganic, nutrients, and heavy metal results analyzed by various EPA methods, and
2) Volatile organic compounds (VOC) analyzedby EPA Methods 524.2 t 82608.
Our review of the groundwater quality data from the November, 2000 Event is not yet complete.
However, cursory review of the VOC compounds indicates that between May, 1999 and November,
2000 the chloroform concentrations increased in two (2) existing IUC monitoring wells, MW-4 and
MW-17 (see attached spreadsheet Split00-11.xIs, tabsheet vocCompare). Previously, undetectable
chloroform concentrations were found in the DRC sample of well MW-17 (ibid., 5ll2l99 sample).
Later, this contaminant was found at detectable concentrations in this well in the DRC November,
2000 sample. Although the MW-17 concentration increase is small, it is noteworthy and will
continue to be of interest to the DRC in the ongoing chloroform contamination investigation.
Another VOC compound of DRC interest is tetrahydrofuran. This compound was tentatively
identified in the May , 1999 DRC sample results for three (3) existing IUC monitoring wells, MW- I ,
MW-3, and MW-12. Review of the DRC November, 2000 data suggests the tetrahydrofuran
Ms. Michelle Rehmann

continues to be found in these same three (3) wells, and has increased in concentration (see attached
spreadsheet). As a result, this compound will also continue to be of interest to the DRC in future
split sampling events at the White Mesa facility.
As our review of the November, 2000 Event data progresses, we will pass along our findings as soon
as they are available. If you have any questions regarding the attached data, or the preliminary
findings mentioned above, please contact me at (80I) 536-4262.
