2.1.2. GroundwaJpr Hqad Monitorine
Depth to groundwater was taken in the following wells and/or piezometers during the
Quarter:
a) All of the chloroform contaminant investigation wells listed in paragraph 2.1.1
Groundwater
In addition, weekly depth to groundwater measurements were taken in MW-4, TW4-15
(MW-26), TW4-19 and TW4-20, as part of the long term pumping test for MW-4.
2.2, Sampling Methodology, Equipment and Decontamination Procedures
The sampling methodology, equipment and decontamination procedures that were
performed foi tfue chloroform contaminant investigation during the Quarter can be
summarized as follows:
2.2.1. Well Pureine and Depth to Groundwater
a) A list is gathered of the wells in order of increasing chloroform contamination.
The order for purging is thus established. Mill personnel start purging with all of
the non-deteci wJlk-and then move to the more contaminated wells in order of
chloroform contamination, starting with the wells having the lowest chloroform
contamination; and
b) Before leaving the Mill office, the pump and hose are rinsed with de-ionized
(*DI') water. Mill personnel then proceed to the first well which is the well
indicating the lowest concentration of chloroform based on the previous quarters
sampling results. Well depth measurements are taken and the two casing
volumes are calculated (measurements are made using the same instrument used
for the monitoring wells under the Mill's GWDP). The Grundfos pump (a 6 gpm
pump) is then lowered to the bottom of the well and purglng is begun. At the
first well, the purge rate is established for the purging event by using a calibrated
5 gallon bucket. After the evacuation of the first well has been completed, the
pu-p is removed from the well and the process is repeated at each well location
*orirrg from least contaminated to most contaminated. All wells are capped and
secured prior to leaving the sampling location.
2.2.2. Safnpling
a) Following the purging of all chloroform investigation wells, the sampling takes
place (usually the next morning). Prior to leaving the Mill office to sample, a
cooler along with blue ice is prepared. The trip blank is also gathered at that time
above on October 14,2008;
b) The point of compliance monitoring wells under the Mill's
Discharge Permit (*GWDP") on November 3-13, 2008.
c) Piezometers - P-1, P'2,P'3,P-4, and P-5 on November 25,2008'
(the trip blank for these events is provided by the Analytical Laboratory). Once
Mill Personnel arrive at the well sites, labels are filled out for the various samples
to be collected. All personnel involved with the collection of water and samples
are the outfitted with rubber gloves. Chloroform investigation samples are
collected by means of dedicated bailers and the wells are purged by means of a
dedicated portable pump. Each quarterly pumping and sample collection event
begins at the location least affected by chloroform (based on the previous
quarters sampling event) and proceeds by affected concentration to the most
affected locaiion.- The dedicated portable pump is appropriately decontaminated
prior to each purging sampling event and the QA rinsate sample is collected after
said decontamination but prior to.the commencement of the sampling event.
b) Mill personnel use a disposable bailer to sample each well. The bailer is attached
to a riel of approximately 150 feet of nylon rope and then lowered into the well.
After cominglnto contact with the water, the bailer is allowed to sink into the
water in order to fill. Once full, the bailer is reeled up out of the well and the
sample bottles are filled as follows;
(i) First, a set of VOC vials is filled. This set consists of three 40 ml vials
provided by the Analytical Laboratory. The set is not filtered and is
preserved with HCL;(ii) Second, a 500 ml sample is collected for NihatesA.litrites. This sample is
also not filtered and is preserved with H2SO4 (the bottle for this set is
also provided by the Analytical Laboratory);
(iiD Third, a 500 ml sample is collected for Chloride. This sample is not
filtered and is not Preserved; and
c) After the samples have been collected for a particular well, the bailer is disposed
of and the samples are placed into the cooler that contains blue ice. The well is
then recapped and Mill personnel proceed to the next well.
DUSA completed (and transmitted to UDEQ on May 25, 2006) a revised Quality
Assurance Plan ("QAP") for sampling under the Mill's GWDP. The GWDP QAP was
reviewed by UDEQ and has been approved for implementation. The QAP provides a
detailed presentation of procedures utilized for groundwater sampling activities under the
GWDP. While the water sampling conducted for chloroform investigation purposes has
been conformant with the general principles set out in the QAP, some of the requirements
in the QAP were not fully implemented prior to UDEQ's approval for reasons set out in
corespondence to UDEQ dated December 8, 2006. Subsequent to the delivery of the
Decernber 8, 2006 letter, DUSA discussed the issues brought forward in the letter with
UDEQ and has received correspondence from UDEQ about those issues. In response to
UDEQ's letter and subsequent discussions with UDEQ, DUSA has incorporated changes
in chloroform QA procedures in the form of a separate document. The chloroform QA
document describes the differing needs of the chloroform investigation progftIm, and is
and attachment to the GWDP QAP where QA needs other than those described in the
chloroform QA document are addressed.
2.3 Field Data Worksheets
Attached under Tab B are copies of all Field Data worksheets that were completed
during the euarter for the chloroform contaminant investigation monitoring wells listed
in paragraptr2.l.l above and sampled October 15, 2008'
2.4 Depth to Groundwater Sheets
Attached under Tab C are copies of the Depth to Water Sheets for the weekly monitoring
of MW-4, TW4-15 (MW-26), TW4-19 and TW4-20 as well as the monthly depth to
groundwater monitoring data for chloroform contaminant investigation wells measured
during the quarter. bepth-to-groundwater measurements which were utilized for
groun-<lwater contours are included on the Field Data Worksheets at Tab B of this report'
3. DATA INTERPRETATION
3.1. Interpretation of Groundwater Levels, Gradients and Flow Directions'
3.1.1. Current Site,Grou4Swater Contour Map
The contour map uses the October 14, 2008 data for the wells listed in paragraph 2'l'2 (a)
above, Novernber 3-13, 2008 data for the wells listed in paragraph 2.1.2 (b), and
November 25,,2008 for the piezometers and wells listed in paragraph 2'l'2 (c) above'
Also included under Tab D is a groundwater contour map of the portion of the Mill site
where the four chloroform purnping wells are located, with hand-drawn stream tubes, in
order to dernonstrate hydraulic capture from the pumping
3.1.2
Maps f,or Previous O\rarter
The groundwater contour maps for the Mill site for the third quarter of 2008, as.submitted
with the Chloroform Monitoring Report for the third quarter of 2008, are attached under
Tab E.
A comparison of the water table contour maps for the Quarter to the water table contour
maps fir the previous quarter indicates similar patterns of drawdown related to pumping
of MW-+, MW-ZO 1fW+-tS;, TW4-19 ana iW+-ZO. Water levels and water level
contours for the site have not changed significantly since the last quarter, except for a few
locations.
Reported increases in water levels of approximately 5 feet in MW-19 and of
approximat ely 17 feet in pumping well TW4-19 occurred. The increase at MW-19 yields
a water level more typical of historical measurements at this well.
4
Water level fluctuations at pumping wells MW-4, MW-26 (TW4-15), TW4-19, and
TW4-20 are due in part to fluctuationr in pumping conditions just prior to_and at the time
the measurements are taken. The largesi increase (decrease in drawdown), of
approximately 17 feet, occurred at TW4-19'
3.1.3 Hydroeraohs
Attached under Tab F are hydrographs showing groundwater elevation in each
chloroform contaminant investigation monitor well over time.
3.r.4
Attached under Tab G are tables showing depth to groundwater measured and
groundwater elevation over time for each of the wells listed in Section 2.1.1 above.
3.1.5 Evaluation of the Effectiveness of Hydr,aulic Capture
perched water containing chloroform has been removed from the subsurface by pumping
Mw-4, Tw4-19, Mw-2; (Tw4-15), and TW4-20. The purpose of the pumping is to
reduce total chloroform mass in the perched zone as rapidly as is practical. These wells
were chosen for pumping because l) they are located in areas of the perched zone having
relatively high ;#.uU1tty and saturated thickness, and 2) high concentrations of
chloroform *"r. d"t""ted at these locations. The relatively high transmissivity of the
perched zone in the vicinity of the pumping wells results in the wells having a relatively
'trigh proauctivity. The combination of relatively high productivity and high chloroform
concentrations allows a high rate of chloroform mass rernoval.
The impact of pumping these wells is indicated by the water level contour maps attached
under Tabs D i"a n. don"r of depression have developed in the vicinity of the pumping
wells which continue to rernove iignificant quantities of chloroform from the perched
zone. The water level contour maps indicate that effective capture of water containing
high chloroform concentrations in the vicinity of the pumping wells is occurring. As
noted in Section 3.1.2, an increase in water level (decrease in drawdown) occurred at
TW4-19 between the third and fourth quarters of 2008. Overall, the combined capture of
TW4-19, TW4-20, MW4 and MW-26 (TW4-15) has not changed significantly since the
last quarter. The large decrease in drawdown at TW4-19 has decreased the apparent
capture zone of this well relative to that of other nearby pumping wells.
Although high chloroform concentrations exist at some locations downgradient of the
pumping *.llr 1fo. example, near TW4-4), the low permeability of the perched zone at
these locations would prevent significant rates of chloroform mass removal should these
wells be pumped. Bypumping at the more productive, upgradient locations, however,
the rate of Oo*ngraaiint ttrtoroform migration will be diminished because of the
reduction in hydraulic gradients, and natural attenuation will be more effective

results for groundwater quality monitoring conducted Y9:t the chloroform contaminant
investigation during the Quarter, in Conima Separated Values (CSV)' A copy of the
transmittal e-mail is included under Tab I'
3.2.3
Included under Tab J of this Report is a current chloroform isoconcentration map for the
Mill site.
Attached under Tab K is a table summarizing chloroform and nitrate values for each well
over time.
Attached under Tab L are graphs showing chlorolorm concentration trends in each
monitor well over time. As TW4-14 *u, p.&iously dry and wells TW4'23,4-24 and 4-
25 have limited aii, u trend graph for that weli has not been included but will be
included with the ;if'a;;tipott as sufficient data will have been collected at that
time.
3.2.5 Analvsis of Analytical Rgslrlts
Comparing the analytical results to those of the previous quarter, as summarized in the
table incli<1ed undeiTab K, the following observations can be made:
Chloroform concentrations have increased by more than-1}% in the following
*.ttt, compared to last quarter: TW4-10, TW4-15, and TW4-21'
Chloroform concentrations have decreased by more than 20Vo in the following
wells, compared to last quarter: TW4-16 andTW4-22;
within 20% it the following wells
TW4-2, TW4-4, TW4-5, TW4-6,c) Chloroform concentrations have remained
compared to last quarter: MW-4, TW4-1,
TW4-7, TW4-11, TW4-18, and TW4-19;

In addition, between the third and fourth quarters of 2008, the chloroform concentration
in well TW4-Z:, increased from 120 pgi- to 170 pgtL, and the concentration in well
Tw4-zzdecreased from 6,300 p{L to An pgt. wslls Tw4-23 and TW4-25 rernained

p"glL to non detect. Tw4:24,located west of TW4-22, and TW4-25, located north of
fll+-Zt,bound the chloroform plume to the west and north.
Chloroform concentrations in TW4-6, which was the most downgradient temporary
perched well prior to installation of ternporary well TW4-23, decreased from 39 to 37
ugt.This wejl has likely remained outside the chloroform plume due to a combination
of l) slow rates of downgradient chloroform migration in this area due to low
permeability conditions and Ihe effects of upgradient chloroform removal by pumping,
and 2)natural attenuation. Both TW4-6 ana tW+-23 bound the chloroform plume to the
south.
3.3. Quality Assurance Evaluation And Data validation
euality assurance evaluation and data validation procedures in effect at the time of
J-pfirg were followed. These involve three basic types of evaluations: field QC
checks; -Analytical Laboratory checks; and checks performed by DUSA personnel' as
described below.

3.3.3 Mill QA Manager Review
The Mill QA Manager, which, for these sampling events was DUSA's Manager of
Environmental Affair-s, performed four tlpes of reviews: a determination of whether Mill
sampling personnel foitoweO Mill sampling procedures; a review of the results from the
fiela eC Checks; a review of analytical reports for holding times and qualiffing
indicators for the data; and a review of the Analytical Laboratory QA/QC analysis. The
results of the QA Manager's review are discussed below.
a) Adherence to Mill SamPling SOPs
On a review of adherence by Mill personnel to the sampling procedures summarized in
Section 2.2 above, the QA Managei concluded that such procedures had been followed,
however, well TW4-20 was errantly not sampled for organic analytes. More specifically,
a set of samples, including well TW4-20 was sampled in October but did not meet the
ternperature specification for VOC sample receipt and required re-sampling. Due to an
inadvertent error the sampling personnel missed re-collection of well TW4-20 for VOC's
when the re-sampling of these wells occurred.
b) Results From Field QC Checla
The duplicate samples of TW4-17 indicated a relative percent difference within
the prescribed standard of 20% for those parameters duplicated. However,
chloioform presence was indicated in the field blank and rinsate samples. The
matter of continued chloroform presence in these field blank and rinsate samples
remain under investigation on the part of the QA Manager. During the 3'd Quater
report period it was noted that field blank de-ionized water continued to yield
trace volatile organic presence (i.e. Chloroform). This matter was further
investigated by the QA manager and corrective measures included: 1) a
confirmation that purchased de-ionized water had in fact been used for the field
blank and, 2) two sets of 3 purchased de-ionized waters samples were prepared
and duplicate sets were sent to each of two contract laboratories (Energy Lab and
AWAa). Both Labs continued to report the presence of low concentration
Chloroform in all of the purchased water samples (e.g. approximately 30 ppb)t
Concurrently, these low concentrations of Chloroforn were found in the 4"'
Quarter field blanks as well. During the QA review for the preparation of this
report it was discovered that in fact what was purchased is the resin used to treat
the water, and not the water itself. Accordingly, for the l't Quarter, 2009 samples
of pretreated water, treated water and the field blanks thernselves will be
analyzedto further isolate the cause of this low level contaminant source.
c) Review of Analytical Laboratory QA/QC Analysis and Analytical Reports
The QA Manager reviewed the Analytical Laboratory's QA/QC Summary Reports and
made the following conclusions;

4. LONG TERM PUMP TEST AT MW-4, TW4-15 (MW-26), TW4-19 AND
TW4-20, OPERATIONS REPORT
4.1. Introduction
As a part of the investigation of chloroform contamination at the Mill site, IUSA has been
conducting a Long Term Pump Test on MW-4, TW4-19, TW4-15 (MW-26) and TW4-
20. The purpose of the test is to serve as an interim action that will remove a significant
amount of chloroform-contaminated water while gathering additional data on hydraulic
properties in the area of investigation. The following information documents the
operational activities during the Quarter.
4.2. Pump Test Data Collection
The long term pump test for MW4 was started on April 14,2003, followed by the start
of pumping from TW4-19 on April 30, 2003, from TW4-15 (MW-26) on August 8, 2003
and from TW4-20 on August 4,2005. Personnel from Hydro Geo Chem, Inc. were on
site to conduct the first phase of the pump test and collect the initial two days of

monitoring data for MW-4. IUSA personnel have gathered subsequent water level and
pumping data.
Analyses of hydraulic parameters and discussions of perched zone hydrogeology near
MW-4 has been provided by Hydro Geo Chem in a separate report, dated November 12,
2001, and in the May 26,2004 Final Report on the Long Term Pumping Test.
Data collected during the Quarter included the following:
a) Measurernent of water levels at MW-4, TW4-19, TW4-15 (MW-26), and TW4-
20 on a weekly basis, and at selected temporary wells and permanent monitoring
wells on a monthly basis (See Section 3.1 and Tabs B and C for a discussion of
the water levels);
b) Measurement of pumping history:
(i) pumping rates(ii) total pumped volume(iii) operationalandnon-operationalperiods;
c) Periodic sampling of pumped water for chloroform and nitrate & nitrite analysis
and other constituents, as discussed in detail in Section 3.2 above.
4.3. Water Level Measurements
Beginning August 16, 2003, the frequency of water level measurements from MW-4,
TW4-15 (MW-26), and TW4-19 was reduced to weekly. From commencement of
pumping TW4-20, water levels in that well have been measured weekly. Depth to
groundwater in all other chloroform contaminant investigation wells is monitored
monthly. Copies of the weekly Depth to Water monitoring sheets for MW-4, TW4-15
(MW-26), TW4-19 and TW4-20 and the October and Decernber monthly Depth to Water
monitoring sheets for all of the chloroform contaminant investigation wells are typically
included under Tab C but will be transmitted separately on December 1, 2008. Monthly
depth to water measurements for Septernber are recorded in the Field Data Worksheets
included under Tab B.
4.4. Pumping Rates and Volumes
4.4.r. M,W-4
Approximately 91,320 gallons of water were pumped from MW4 during the Quarter.
The average pumping rate from MW-4, when the pump was pumping, wtls
approximately 4.0 gpm throughout the Quarter. The well is not purging
continuously, but is on a delay device. The well purges for a set amount of time and

then shuts offto allow the well to recharge. Water from MW4 was transferred to the
Cell I evaporation pond through a pipeline installed specifically for that purpose. At
the end of the 3rd Quarter,2008, and since commencement of pumping on April 14,
ZOO3, an estimated total of approximately 1,817,460 gallons of water have been
purged from MW-4.TW4'19
4.4.2 TW4-1s (MW-26)
Approximately 589,620 gallons of water were pumped from TW4-19 during the
quarter. The average pumping rate from TW4-19, when the pump was pumping, was
approximately 6.0 gpm throughout the Quarter. The pump in this well is operating on
a delay. It pumps for approximately one and a half minutes and then is off for two to
three minutes. Water from TW4-19 was directly transferred to the Cell I evaporation
pond through a pipeline installed specifically for that purpose. At the end of the I't
Quarter, ZiO7, and since commencement of pumping on April 30, 2003, an estimated
total of approximately 9,223,150 gallons of water have been purged from TW4-19.
4.4.3 TW4-ls (MW-26)
Approximately 55,700 gallons of water were pumped from TW4-15 (MW-26) during
the Quarter. The average flow rate from TW4-15, when the pump was pumping, was
approximately 1.5 gpm throughout the Quarter. The well is not purglng continuously,
Uut is on a delay device. The well now purges for a set amount of time and then shuts
off to allow the well to recharge. The water is directly transferred to the Cell I
evaporation pond through a pipeline installed specifically for that purpose. At the end
of the I't Quarter, 2006, and since commencement of pumping on August 8, 2003, an
estimated total of approximately 1,273,940 gallons of water have been purged from
TW4-15.
4.4.4 TW4-20
Approximately 50,230 gallons of water were pumped from TW4-20 during the
Quarter. The average flow rate from TW4-20, when the pump was pumping' was
approximately 6.0 gpm throughout the Quarter. The well is not purglng continuously
but is on a delay device. The well pump is set on a water elevation device. When the
water reaches a set point, the pump turns on until the water level drops to another set
point. The water is directly transferred to the Cell 1 evaporation pond through a
pipeline installed specifically for that purpose. Since commencement of pumping on
August 4, 2005, an estimated total of approximately 985,650 gallons of water have
been purged from TW4-20.
4.5 Daily Inspections
Denison has submitted an Operations and Maintenance Plan, Chloroform Pumping
System, White Mesa Mill, Blanding, (Jtah,Revision 1.0 to UDEQ for approval. Upon
approval of that plan, the Mill will coflrmence documenting its daily inspections of the
ll
operational status of the chloroform pumping wel! ol the daily inspection form, an
"..*pf" of the form of which is aftachedas Tab M. Operational Problems
No operational problems in the pumping wells were reported during the 3'd Quarter' 2008
period.
4.7 Conditions That May Affect water Levels in Piezometers
No significant amount of water was added to any of the three wildlife diversion ponds
during the Quarter.
4.8 ChloroformAnalYsis
Monthly chloroform sampling ceased on November 8, 2003' From that time all
chloroform contaminant inveJigation wells were sampled on a quarterly basis' The
sample results are discussed above in Section 3'2'
5. CONCLUSIONS AND RECOMMENDATIONS
The water level

contour map for the Quarter indicates that effective capture of water
chloroform concentrat]ons in the vicinity of the pumping wells is
Between the third and fourth quarters of 2008, the chloroform concentration in well
Tw4-z:increased from 120 p/L to 170 pglL, and the concentration in well TW4-22
decreased from 6,t00 pglLto'oio pgr. Fluctuations in concentrations in these wells are
likely related to variaiiJns in pumping in TW4-20 and nearby wells' and their location
near the suspected former office tlactr fietd source area. Regardless of these measured
fluctuations in chloroform concentrations, sampling of temporary we]ls- TW4'24 (located
west of Tw4-22) and TW4-25 (located north ir rw+-zt), indicated these wells remain
outside the chloroform plume and thus bound the plume to the west and north'
Chloroform was not detected at either TW4-24 or TW4-25'
Althouglr there was a general increase in chloroform concentrations inTW4-22 between
the fourth quarter otZiOl and the third quarter of2008, t\e reported relatively-substantial
increase between the second and third qrun"rr of 2008 (from l,2oo ltglL to 6,300 ttdL)
seemed anomalous. The 630 pgll reported at TW4-22 for the fourth quarter of 2008 is
within the pre-third quarter tu.rgl of concentrations measured at this well'
continued pumping of Tw4-19, TW4-20, Mw-4, and Mw-26 (TW4-15) is
recommended. puilping these wells, regardless of any short term fluctuations in
concentrations detecti uI th" wells (such as at TW4-20), helps to reduce downgradient
chloroform migration by rernoving chloroforn mass and reducing average hydraulic
gradients, thereby allowing natural attenuation to be more effective'

The chloroform concentration at downgradient well TW4-6 decreased from 39 to
li pdl,. Although fluctuations in concentrations have occurred, this well has likely
remained outside the chloroform plume due to a combination of l) slow rates of
downgradient chloroform migration in this area due to low permeability conditions and
the efrects of upgradient chl,oroform removal by pumpin8, and 2) natural attenuation'
Chloroform remained non detect at downgradient temporary well TW4-23. Both TW4-6
and TW4-23 bound the chloroform plume to the south

oRrctNAL SAMPLE SUBMTTTAL(S)
All original sample submittals have been returned with the data package,
SAMPLE TEMPERATURE COMPLTANCE: 4.C (r2"C)
Temperature of.samples received may not be considered properly preserved by accepted standards. Samples that arehand delivered immediately after collection shall be considered aiieptable if thlre is evidence that the chilling process hasbegun.
GROSS ALPHA ANALYSIS
Method 900'0 for gross alpha and gross beta is intended. as a drinking water method for low TDS waters. Data provided bythis method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time.is.48 hours (2 days). The time- delay in returning the canister to the laboratory for processingshould be as short as possible to avoid excessive decay. Maximum recomriended delay between end of erporure to -
beginning ofcounting should not exceed 8 days.
SOIUSOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS USING EPA 505
Data for Atrazine and Simazine are reported from EPA 525.2, notfrom EpA 50S. Data reported by ELI using EpA method505 reflects the results for seven individual Aroclors. When the resutts for all seven are r.iO lnot oLGcteol, t-he samptemeets EPA compliance criteria for pCB monitoring.

oRtcr NAL SAMPLE SUBMTTTAL(S)
All original sample submittals have been retumed with the data package.
SAMPLE TEMPEMTURE COMPLIANCE: 4"C (r2.C)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are handdelivered immediately after collection shall be considered acceptable if there isevidence that the chilling process has begun.
GROSS ALPHAANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided bythis method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is.48 hours (2 days). The time delay in retuming the canister to the laboratory for processingshould.be as short as possible to avoid excessive decay. Maximum recommended delay between end ofexp6sure tobeginning of counting should not exceed 8 days.
SOIUSOLIO SAMPLES
All samples reported on an as received basis unless othenrise indicated.
ATRAZINE, SIMAZINEAND PCB ANALYSIS USING EPA 505
Data for Atrazine and simazine are reported from EPA 525.2, not from EPA 505. Data reported by ELI using EpA method505 reflects the results for seven individual Aroclors. When the results for all seven are I.iD (not dLtected), ilre samplemeets EPA compliance criteria for PCB monitoring.
SUBCONTRACTI NG ANALYSIS
subcontracting of sample analyses to an outside laboratory may be required. lf so, ENERGy LABoMToRIES will utilize itsbranch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within theLaboratory Analytical Report.
