As UDEQ is aware, Denison has in the past experienced difficulty in obtaining
chloroform samples from well TW4-14. The difficulty arose from the very limited
recovery rate encountered at that location. More specifically, it is generally necessary
that there be at least 1.5 feet of water within the well in order to obtain a sample which is
not influenced by sedimentation from the bottom of the well. At the request of UDEQ,
the recovery rate from the TW4-14 location was evaluated by bailing and routine water
level measurements in order to determine the necessary time between purging and sample
collection. Such an evaluation was undertaken between September 2l and October 20,
2006 with limited success in water recovery experienced during this study period.
Nonetheless, quarterly samples were able to be collected from well TW4-14 during the
4th Quarter of 2006 and sampling has continued since, including this I't Quarter of 2008.
2.1.2. Groundwater Head Monitoring
Depth to groundwater was taken in the following wells andlor piezometers during the
Quarter:
a) All of the chloroform contaminant investigation wells listed in paragraph 2.1.1
above on3l26l08;
b) All of the point of compliance monitoring wells under the Mill's Groundwater
Discharge Permit ("GWDP") on 3/11 to 3/19/08.
c) Piezometers - P-l ,P-2,P-3, P-4 and P-5 on ll2l08.
In addition, weekly depth to groundwater measurements were taken in MW-4, TW4-15
(MW-26), TW4-19 andTW4-20, as part of the long term pumping test for MW-4.
),Sampling Methodology, Equipment and Decontamination Procedures
The sampling methodology, equipment and decontamination procedures that were
performed for the chloroform contaminant investigation during the Quarter can be
summarized as follows:
Well Purging and Depth to Groundwater
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-detect wells and then move to the more contaminated wells in order of
chloroform contamination, starting with the wells having the lowest chloroform
contamination; and
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 purging 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
pump is removed from the well and the process is repeated at each well location
moving from least contaminated to most contaminated. All wells are capped and
secured prior to leaving the sampling location.
2.2.2. Sampling
a) Following the purging of all chloroform investigation wells, the sampling takes
place (usually the next moming). 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
(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 location. 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 reel of approximately 150 feet of nylon rope and then lowered into the well.
After coming into 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 Analyical Laboratory. The set is not filtered and is
preserved with HCL;(ii) Second, a 500 ml sample is collected for NitratesA,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 requirernents
in the QAP were not fully implemented prior to UDEQ's approval for reasons set out in
correspondence to UDEQ dated December 8, 2006. Subsequent to the delivery of the
December 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 program, 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 Quarter for the chloroform contaminant investigation monitoring wells listed
in paragraph2.I.l above and sampled3126108.
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. Depthto-groundwater measurements collected on October 10,2007
were utilized for groundwater contours are included on the Field Data Worksheets at Tab
B of this report.
3. DATA INTERPRE,TATION
3.1. Interpretation of Groundwater Levels, Gradients and Flow Directions.
3.1.1. Current Site Groundwater Contour Map
Included under Tab D is a water table contour map, which provides the location of all of
the wells and piezometers listed in item 2.1.2 above for which depth to groundwater was
taken during the Quarter, the groundwater elevation at each such well and piezometer,
measured in feet above mean sea level, and isocontour lines to delineate groundwater
flow directions observed during the Quarter's sampling event. The contour map uses the
March 26, 2008 data for the wells listed in paragraph 2.1.2 (a) above, March I I - I 8, 2008
data for the wells listed in paragraph 2.1.2 (b), and January 2, 2008 for the piezometers
listed in paragraph2.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 pumping wells are located, with hand-drawn stream tubes, in
order to demonstrate hydraulic capture from the pumping.
3.1.2. Comparison of Current Groundwater Contour Maps to Groundwater Contour
Maps for Previous Ouarter
r The groundwater contour maps for the Mill site for the fourth quarter of 2007, as
I submitted with the Chloroform Monitoring Report for the fourth quarter of 2007, dated- February 29,2008, are attached under Tab E.
A comparison of the water table contour maps for the Quarter to the water table contour
maps for the previous quarter indicates similar patterns of drawdown related to pumping
of MW-4, MW-26 (TW4-15), TW4-19 and TW4-20. Water levels and water level
contours for the site have not changed significantly since the last quarter, except for a few
locations.
Areportedincreaseinwaterlevelof between 72and 13 feetoccurredinTW4-11,and
reported increases of approximately 4 to 5 feet occurred atMW-27, MW-28, and TW4-
14. The increase in water level at TW4-11 is likely anomalous, however the reported
value was used in preparing the water level contour map. Decreases in water levels of
approximately 5 feet were reported at wells MW-19 and TW4-14. The apparent decreases
in water levels at these wells may be due to measurement error or measurement of water
level shortly after a purging event.
A water level increase of approximately 9 feet occurred at TW4-19, and an increase of
approximately 13 feet occurred at TW4-20. The water level at MW-4 decreased by
approximately 6 feet. Water level fluctuations in these pumping wells are due in part to
fluctuations in pumping conditions just prior to and at the time the measurements are
taken
3.1.3. Hydrographs
Attached under Tab F are hydrographs showing groundwater elevation in each
chloroform contaminant investigation monitor well over time.
3.I.4. Depth to Groundwater Measured and Groundwater Elevation
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.
Evaluation of the Effectiveness of Hydraulic Capture
Perched water containing chloroform has been removed from the subsurface by pumping
MW-4, TW4-19, MW-26 (formerly TW4-15), andTW4-20. 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 1) they are located in areas of the perched zone
having relatively high permeability and saturated thickness, and 2) high concentrations of
chloroform were detected 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
high productivity. The combination of relatively high productivity and high chloroform
concentrations allows a high rate of chloroform mass removal.
The impact of pumping these wells is indicated by the water level contour maps attached
under Tabs D and E. Cones of depression have developed in the vicinity of the pumping
wells which continue to remove significant 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, increases in measured water levels (decreases in drawdowns)
occurred at pumping wells TW4-19 and TW4-20, and a decrease in water level (increase
in drawdown) occurred at MW4 between the third quarter of 2007 and the first quarter
of 2008. Overall, the combined capture of TW4-19,TW4-20, MW-4 and MW-26 (TW4-
l5) has not changed significantly, but has decreased slightly, since the last quarter.
Although high chloroform concentrations exist at some locations downgradient of the
pumping wells (for 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. By pumping at the more productive, upgradient locations, however,
the rate of downgradient chloroform migration will be diminished because of the
reduction in hydraulic gradients, and natural attenuation will be more effective.

3.2.4 Data and Graphs Showing Chloroform Concentration Trends
Attached under Tab K is a table summarizing chloroform and nitrate values for each well
over time. TW4-14 had a small amount of water just sufficient for sampling (see the
discussion in Section 2.1.1 above)
Attached under Tab L are graphs showing chloroform concentration trends in each
monitor well over time. As TW4-14 was previously dry, a trend gaph for that well has
not been included.
3.2.5 Analysis of Analytical Results
Comparing the analytical results to those of the previous quarter, as summarized in the
table included under Tab K, the following observations can be made:
a) Chloroform concentrations have increased by more than 20o/o in the following
wells, compared to last quarter: TW4-6, TW4-10, TW4-16, TW4-19, TW4-20,
TW4-21, andTW4-22.
b) Chloroform concentrations have decreased by more than 20o/o in the following
wells, compared to last quarter: TW4-9, TW4-11, and TW4-15;
c) Chloroform concentrations have remained within 20o/o in the following wells
compared to last quarter: MW-4, TW4-1, TW4-2,TW4-4, TW4-5, TW4-7, and
TW4-18;
d) Chloroform concentrations at TW4-8 decreased from 3.5 pglLto non-detect; and
e) TW4-3, TW4-12, TW4-13, TW4-14, MW-32 (TW4-17), TW4-23, and TW4-25
remained non-detect.
In addition, between the fourth quarter of 2007 and the first quarter of 2008, the
chloroform concentration in well TW4-20 increased from 9,000 ytg/Lto 13,000 1t$L,the
concentration in TW4-21 increased from 120 ltglL to 390 ttglL, and the concentration in
TW4-22 increased from 440 ltglL to t,400 p/L. Wells TW4-23 and TW4-25 remained
non-detect for chloroform, and the concentration in well TW4-24 remained at I.5 1tglL.Tw4-24,located west of Tw4-22, and TW4-25, located north of Tw4-21, 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 temporary well TW4-23, increased from 18 to 52
Itg/L, although this well continues to remain outside the plume. This well has likely
remained outside the chloroform plume due to a combination of 1) slow rates of
downgradient chloroform migration in this area due to low permeability conditions and

the effects of upgradient chloroforn removal by pumping, and 2) natural attenuation.
Both TW4-6 and TW4-23 bound the chloroform plume to the south.
3.3. Quality Assurance Evaluation And Data Validation
Quality assurance evaluation and data validation procedures in effect at the time of
sampling were followed. These involve three basic types of evaluations: field QC
checks; Analytical Laboratory checks; and checks performed by DUSA personnel, as
described below.
3.3.1 Field OC Checks
Field Quality Control samples for the chloroform investigation program consist of a field
duplicate sample, a field blank and a trip blank. These check samples are to be generated
for each quarterly sampling episode. During the 1't Quarter of 2008 duplicates (TW4-65,
duplicate of TW4-20 and TW4-70, duplicate of Tw4-17), a DI blank (TW4-60), an
equipment rinsate sample (TW4-63) and a trip blank were collected and analyzed. The
results of these analyses are included with the routine analyses under Tab H.
3.3.2 Analytical Laboratory OA/OC Procedures
The Analytical Laboratory has provided summary reports of the analyical quality
assurance/quality control (QA/QC) measurements necessary to maintain conformance
with NELAC certification and reporting protocol. The Analytical Laboratory QA/QC
Summary Report, including copies of the Mill's Chain of Custody and Analytical
Request Record forms, for the November sampling event, are included under Tab H.
3.3.3 Mill OA Manager Review
The Mill QA Manager, which, for these sampling events was DUSA's Manager of
Environmental Affairs, performed four types of reviews: a determination of whether Mill
sampling personnel followed Mill sampling procedures; a review of the results from the
Field QC Checks; a review of analytical reports for holding times and qualifying
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 Manager concluded that such procedures had been followed.
b) Results From Field QC Checl<s
The duplicate samples of TW4-17 and TW4-20 indicated a relative percent difference
(RPD) outside the prescribed standard of 20Yo for Nitrogen, Nitrate + Nitrite as N

(-134.55%) and for Methylene Chloride (22.22%) for the MW-20 duplicate sampling
and all parameters were within the limitation for the TW4-17 duplication exercise. As
such the results fo Nitrogen, Nitrate + Nitrite as N and for Methylene Chloride are
provided with qualification relative to duplicability of data. The results of the QC
evaluation of duplicate samples for this lt't Quarter, 2008 event is provided in the table
below:
The quarterly results over time have shown improvement in the presence of chloroform
in the field blank and rinsate sample. This quarters field blank TW4-60 and the
equipment rinsate blank TW4-63 found chloroform in minor concentrations slightly
above the reporting limit (1.0 ug/L) atl.l uglL and 1.5 ug/L respectively. In addition,
the rinsate blank indicated the presence of Nitrogen, Nitrate + Nitrite as N at the reporting
limit (0.1 ug/L). The QA Manager intends to research the applicability of RPD
determinations on field duplicates of difficult measurements such as VOC's prior to the
next reporting period.
In response to these conditions, the QA Manager has previously investigated possible
causes of Quality Assurance anomalies in the chloroform sampling data. The areas of
inquiry have included possible sources of chloroform from the DI distribution system and
methods of sample duplication. As was observed for the 3'd Quater period, the DI blank
and equipment rinsate sample results (TW4-60 and TW4-63) were non-detect suggesting
that the installation of a carbon filtration unit in the DI water generation process was
successful. In reviewing the results of chloroform duplicate data, the QA manager has
discussed this matter with sampling personnel and it is believed that collecting sequential
duplicate samples from pumping wells may be resulting in differences between samples.
Accordingly, the sampling staff have been re-instructed to collect duplicate samples only
from non-pumping chloroform wells. The QA Manager has discussed the issue of matrix
interference in chloroform analyses with the contract laboratory but this complexity in the
analytical system remains at issue and can result in low false detection of compounds. As
a means of better understanding the issue and the Laboratory's culpability for low
concentration findings of chloroform in equipment rinsate and field blanks, the Mill staff
prepared blind samples of bottled water for analyses by the Laboratory. The results of
this QC check did not find inconsistent results or anomalous VOC compounds.
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;

All qualifiers and the corresponding explanations in the summary reports
are reviewed by the QA Manager. The qualifiers, except one, reported
were for matrix interference in chloroform analyses in some of the
analyzed monitoring location samples, however, the results exceeded the
re-established reporting limit. The other qualifying data were for spike
recovery on a surrogate analysis for methylene chloride, however, the
other surrogate analyses were acceptable and the analytical result was a
non-detect.
The laboratory holding time for all analyses was within chloroform
specification and sample temperature was acceptable upon receipt.

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. DUSA 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) Measurement 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:
(D 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 are included under Tab C. Monthly depth-to-water
measurements for October are recorded in the Field Data Worksheets included under Tab
B.
4.4, Pumping Rates and Yolumes
4.4.1. MW-4
Approximately 83,950 gallons of water were pumped from MW-4 during the Quarter.
The average pumping rate from MW-4, when the pump was pumping, was approximately

4.0 glm 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 off to allow the well to
recharge. Water from MW-4 was transferred to the Cell I evaporation pond through a
pipeline installed specifically for that pu{pose. At the end of the 3rd Quarter, 2007, and
since commencement of pumping on April 14,2003, an estimated total of approximately
1,581,960 gallons of water have been purged from MW-4.
4.4.2. TW4-19
Approximately 304,784 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 3.1 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 1 evaporation pond
through a pipeline installed specifically for that purpose. At the end of the l't Quarter,
2007, and since commencement of pumping on April 30, 2003, an estimated total of
approximately 7,724,200 gallons of water have been purged from TW4-19.
4.4.3. TW4-1s (MW-26)
Approximately 47,780 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 5.5 glm throughout the Quarter. The well is not purglng continuously, but
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 l't
Quarter, 2006, and since commencement of pumping on August 8,2003, an estimated
total of approximately l,ll2,I20 gallons of water have been purged from TW4-15.
4.4.4. TW4-20
Approximat ely 66,52Ogallons of water were pumped from TW4-z}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 purging 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 I evaporation pond through a pipeline installed
specifically for that purpose. Since commencement of pumping on August 4,2005, an
estimated total of approximately 842,800 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, Utah, Revision 1.0 to UDEQ for approval. Upon
approval of that plan, the Mill will commence documenting its daily inspections of the
t2
operational status of the chloroform pumping wells on the daily inspection form, an
example of the form of which is attached as Tab M.
4.6 Operational Problems
On2l25/08 a meter at TW4-19 was found inoperable and was replaced the next day.
Also, the pump at well TW4-19 was found to be clogged and was replaced that day.
4.7 Conditions That May Affect Water Levels in Piezometers
No water was added to any of the three wildlife diversion ponds during the Quarter.
5. CONCLUSIONS AND RECOMMENDATIONS
The water level contour map for the Quarter indicates that effective capture of water
containing high chloroform concentrations in the vicinity of the pumping wells is
occurring.
Between the fourth quarter of 2007 and the first quarter of 2008, the chloroform
concentration in well TW4-20 increased from 9,000 pElL to 13,000 VdL, the
concentration in TW4-21 increased from 120 1tg/L to 390 pglL, and the concentration in
TW4-22 increased from 440 pglL to I,400 pglL. Fluctuations in concentrations in these
wells are likely related to variations in pumping in TW4-20 and nearby wells, and their
location near the suspected former office leach field source area. Regardless of these
measured fluctuations in chloroform concentrations, sampling of temporary wells TW4-
24 (located west of TW4-22) and TW4-25 (located north of TW4-21), indicated these
wells remain outside the chloroform plume and thus bound the plume to the west and
north. Chloroform was not detected at TW4-25 and was detected at a concentration of
less than 2 pdL atTW4-24.
Continued pumping of TW4-19, TW4-20, MW-4, and MW-26 is recommended.
Pumping these wells, regardless of any short term fluctuations in concentrations detected
at the wells (such as at TW4-20), helps to reduce downgradient chloroform migration by
removing chloroform mass and reducing average hydraulic gradients, thereby allowing
natural attenuation to be more effective.
The chloroform concentration at downgradient well TW4-6 increased from 18 to
52 pglL. Although fluctuations in concentrations have occurred, this well has likely
remained outside the chloroform plume due to a combination of 1) slow rates of
downgradient chloroform migration in this area due to low permeability conditions and
the effects of upgradient chloroform removal by pumping, and 2) nafaral attenuation.
Chloroform remained non detect at downgradient temporary well TW4-23. Both TW4-6
and TW4-23 bound the chloroform plume to the south.

THIS IS THE FINAL PAGE OF THE LABORATORY ANALYTICAL REPORT
oRrcr NAL SAMPLE SUBMTTTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4'C (*2"C)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are
hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process
has begun.
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
by this 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 processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIUSOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRMINE, SIMAZINE AND PCB ANALYSIS USING EPA 505
Dala for Atrazine and Simazine are reported from EPA 525.2, nol from EPA 505. Data reported by ELI using EPA method
505 reflects the results for seven individual Aroclors. When the results for all seven are ND (not detected), the sample
meets EPA compliance criteria for PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. lf so, ENERGY LABOMTORIES will utilize
