above on October 14 2008
The point of compliance monitoring wells under the Mills Groundwater
Discharge Permit GWDP on November 3-13 2008
Piezometers P-l P-2 P-3 P-4 and P-S on November 25 2008
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 for the chloroform contaminant investigation during the Quarter can be
summarized as follows
2.2.1 Well Purging and Depth to Groundwater
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-ionizedDIwaterMillpersonnelthenproceedtothefirstwellwhichisthewell
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 Mills GWDP The Grundfos pump 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 calibrated
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
Following the purging of all chloroform investigation wells the sampling takes
place usually the next morning Prior to leaving the Mill office to sample
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
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
Mill personnel use disposable bailer to sample each well The bailer is attached
to 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
First 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 500 ml sample is collected for Nitrates/Nitrites This sample is
also not filtered and is preserved with H25O4 the bottle for this set is
also provided by the Analytical Laboratory
iii Third 500 ml sample is collected for Chloride This sample is not
filtered and is not preserved and
After the samples have been collected for 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 revised Quality
Assurance Plan QAP for sampling under the Mills GWDP The GWDP QAP was
reviewed by UDEQ and has been approved for implementation The QAP provides
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 UDEQs approval for reasons set out in
correspondence to UDEQ dated December 2006 Subsequent to the delivery of the
December 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
UDEQs letter and subsequent discussions with UDEQ DUSA has incorporated changes
in chloroform QA procedures in the form of 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 are copies of all Field Data Worksheets that were completed
during the Quarter for the chloroform contaminant investigation monitoring wells listed
in paragraph 2.1 .1 above and sampled October 15 2008
2.4 Depth to Groundwater Sheets
Attached under Tab 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 Depth-to-groundwater measurements which were utilized for
groundwater contours are included on the Field Data Worksheets at Tab of this report
DATA INTERPRETATION
3.1 Interpretation of Groundwater Levels Gradients and Flow Directions
3.1.1 Current Site Groundwater Contour Map
The contour map uses the October 14 2008 data for the wells listed in paragraph 2.1.2
above November 3-13 2008 data for the wells listed in paragraph 2.1.2 and
November 25 2008 for the piezometers and wells listed in paragraph 2.1.2 above
Also included under Tab is 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
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
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 few
locations
Reported increases in water levels of approximately feet in MW-19 and of
approximately 17 feet in pumping well TW4-19 occurred The increase at MW-19 yields
water level more typical of historical measurements at this well
Water level fluctuations at pumping wells MW-4 MW-26 TW4-15 TW4-19 and
TW4-20 are due in part to fluctuations in pumping conditions just prior to and at the time
the measurements are taken The largest increase decrease in drawdown of
approximately 17 feet occurred at TW4-19
3.1.3 Hydrographs
Attached under Tab are hydrographs showing groundwater elevation in each
chloroform contaminant investigation monitor well over time
3.1.4 Depth to Groundwater Measured and Groundwater Elevation
Attached under Tab are tables showing depth to groundwater measured and
groundwater elevation over time for each of the wells listed in Section Li above
3.1.5 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 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 they are located in areas of the perched zone having
relatively high permeability and saturated thickness and 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 relatively
high productivity The combination of relatively high productivity and high chloroform
concentrations allows high rate of chloroform mass removal
The impact of pumping these wells is indicated by the water level contour maps attached
under Tabs and 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 an increase in water level decrease in drawdown occurred at
TW4-i9 between the third and fourth quarters of 2008 Overall the combined capture of
TW4-19 TW4-20 MW-4 and MW-26 TW4-15 has not changed significantly since the
last quarter The large decrease in drawdown at TW4-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 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 Interpretation of Analytical Results
3.2.1 Copy of Laboratory Results
Included under Tab of this Report are copies of all laboratory analytical results for the
groundwater quality samples collected under the chloroform contaminant investigation
on September 10 2008 along with the laboratory analytical results for trip blank
3.2.2 Electronic Data Files and Format
DUSA has provided to the Executive Secretary an electronic copy of all laboratory
results for groundwater quality monitoring conducted under the chloroform contaminant
investigation during the Quarter in Comma Separated Values CSV copy of the
transmittal e-mail is included under Tab
3.2.3 Current Chloroform Isoconcentration Map
Included under Tab of this Report is current chloroform isoconcentration map for the
Mill site
3.2.4 Data and Graphs Showing Chloroform Concentration Trends
Attached under Tab is table summarizing chloroform and nitrate values for each well
over time
Attached under Tab are graphs showing chloroform concentration trends in each
monitor well over time As TW4-14 was previously dry and wells TW4-23 4-24 and 4-
25 have limited data trend graph for that well has not been included but will be
included with the Quarter report as sufficient data will have been collected at that
time
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 the following observations can be made
Chloroform concentrations have increased by more than 20%in the following
wells compared to last quarter TW4-lO TW4-15 and TW4-2l
Chloroform concentrations have decreased by more than 20%in the following
wells compared to last quarter TW4-16 and TW4-22
Chloroform concentrations have remained within 20%in the following wells
compared to last quarter MW-4 TW4-l TW4-2 TW4-4 TW4-5 TW4-6
TW4-7 TW4-11 TW4-18 and TW4-19
Chloroform concentrations at TW4-24 decreased from 2.9 gg/L to non detect
and
TW4-3 TW4-8 TW4-9 TW4-12 TW4-13 TW4-14 MW-32 TW4-17 TW4-
23 and TW4-25 remained non-detect
In addition between the third and fourth quarters of 2008 the chloroform concentration
in well TW4-21 increased from 120 j.tg/L to 170 jiglL and the concentration in well
TW4-22 decreased from 6300 gg/L to 630 gg/L Wells TW4-23 and TW4-25 remained
non-detect for chloroform and the concentration in well TW4-24 decreased from 2.9
gg/L to non detect TW4-24 located west of TW4-22 and TW4-25 located north of
TW4-2 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 decreased from 39 to 37
g/L This well has likely remained outside the chloroform plume due to combination
of slow rates of downgradient chloroform migration in this area due to low
permeability conditions and the effects of upgradient chloroform removal by pumping
and 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 field
duplicate sample field blank and trip blank These cheek samples are to be generated
for each quarterly sampling episode During the 4th Quarter of 2008 duplicate TW4-
65 duplicate of TW4-17 DI blank TW4-60 rinsate TW-4-63 and trip blank
were collected and analyzed The results of these analyses are included with the routine
analyses under Tab
3.3.2 Analytical Laboratory OA/OC Procedures
The Analytical Laboratory has provided summary reports of the analytical 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 Mills Chain of Custody and Analytical
Request Record forms for the September sampling event are included under Tab
3.3.3 Mill OA Manager Review
The Mill QA Manager which for these sampling events was DUSAs Manager of
Environmental Affairs performed four types of reviews determination of whether Mill
sampling personnel followed Mill sampling procedures review of the results from the
Field QC Checks review of analytical reports for holding times and qualifying
indicators for the data and review of the Analytical Laboratory QAJQC analysis The
results of the QA Managers review are discussed below
Adherence to Mill Sampling SOPs
On 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
however well TW4-20 was errantly not sampled for organic analytes More specifically
set of samples including well TW4-20 was sampled in October but did not meet the
temperature 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 VOCs
when the re-sampling of these wells occurred
Results From Field QC Checks
The duplicate samples of TW4-17 indicated relative percent difference within
the prescribed standard of 20%for those parameters duplicated However
chloroform 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 31 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
confirmation that purchased de-ionized water had in fact been used for the field
blank and two sets of purchased de-ionized waters samples were prepared
and duplicate sets were sent to each of two contract laboratories Energy Lab and
AWAL Both Labs continued to report the presence of low concentration
Chloroform in all of the purchased water samples e.g approximately 30 ppb
Concurrently these low concentrations of Chloroform were found in the 4th
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 1st Quarter 2009 samples
of pretreated water treated water and the field blanks themselves will be
analyzed to further isolate the cause of this low level contaminant source
Review ofAnalytical Laboratory QA/QC Analysis and Analytical Reports
The QA Manager reviewed the Analytical Laboratorys QAQC Summary Reports and
made the following conclusions
Check samples were analyzed for each method used in analyzing the
Chloroform investigation samples These methods were
Parameter Method
Nitrogen Nitrate Nitrite as E353.2
Chloroform E624
Carbon tetrachioride E624
Chioromethane E624
Methylene chloride E624
Chloride A4500-CL
ii The check samples included at least the following method blank
laboratory control spike sample matrix spike and matrix spike
duplicate
iii All qualifiers if any and the corresponding explanations in the summary
reports are reviewed by the QA Manager The only qualifiers reported
were for matrix interference in some of the analyzed monitoring location
samples however the reporting limit was maintained below the
parameter standard in these instances
iv The laboratory holding time for all analyses was within chloroform
specification and sample temperature was acceptable upon receipt
LONG TERM PUMP TEST AT MW-4 TW4-15 MW-26 TW4-19 AND
TW4-20 OPERATIONS REPORT
4.1 Introduction
As part of the investigation of chloroform contamination at the Mill site IUSA has been
conducting 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 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 MW-4 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 2003
and from TW4-20 on August 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 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
Measurement of water levels at MW-4 TW4-19 TW4-15 MW-26 and TW4-
20 on weekly basis and at selected temporary wells and permanent monitoring

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-l9 and TW4-20 and the October and December monthly Depth to Water

depth to water measurements for September are recorded in the Field Data Worksheets
included under Tab
4.4 Pumping Rates and Volumes
4.4.1 MW-4
Approximately 91320 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 gpm throughout the Quarter The well is not purging
continuously but is on delay device The well purges for set amount of time and
10
then shuts off to allow the well to recharge Water from MW-4 was transferred to the
Cell evaporation pond through pipeline installed specifically for that purpose At
the end of the 3rd Quarter 2008 and since commencement of pumping on April 14
2003 an estimated total of approximately 1817460 gallons of water have been
purged from MW-4 TW4-1
4.4.2 TW4-15 MW-26
Approximately 589620 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
delay It pumps for approximately one and half minutes and then is off for two to
three minutes Water from TW4-19 was directly transferred to the Cell evaporation
pond through pipeline installed specifically for that purpose At the end of the Vt
Quarter 2007 and since commencement of pumping on April 30 2003 an estimated
total of approximately 9223150 gallons of water have been purged from TW4-19
4.4.3 TW4-15 MW-26
Approximately 55700 gallons of water were pumped from TW4-1 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 purging continuously
but is on delay device The well now purges for set amount of time and then shuts
off to allow the well to recharge The water is directly transferred to the Cell
evaporation pond through pipeline installed specifically for that purpose At the end
of the 1st Quarter 2006 and since commencement of pumping on August 2003 an
estimated total of approximately 1273940 gallons of water have been purged from
TW4-15
4.4.4 TW4-20
Approximately 50230 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 purging continuously
but is on delay device The well pump is set on water elevation device When the
water reaches set point the pump turns on until the water level drops to another set
point The water is directly transferred to the Cell evaporation pond through
pipeline installed specifically for that purpose Since commencement of pumping on
August 2005 an estimated total of approximately 985650 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
11
operational status of the chloroform pumping wells on the daily inspection form an
example of the form of which is attached as Tab Operational Problems
No operational problems in the pumping wells were reported during the 3fh 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 Chloroform Analysis
Monthly chloroform sampling ceased on November 2003 From that time all
chloroform contaminant investigation wells were sampled on quarterly basis The
sample results are discussed above in Section 3.2
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 third and fourth quarters of 2008 the chloroform concentration in well
TW4-2 increased from 120 pg/L to 170 jig/L and the concentration in well TW4-22
decreased from 6300 jig/L to 630 pg/L 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 either TW4-24 or TW4-25
Although there was general increase in chloroform concentrations in TW4-22 between
the fourth quarter of 2007 and the third quarter of 2008 the reported relatively substantial
increase between the second and third quarters of 2008 from 1200 j.tg/L to 6300 jig/L
seemed anomalous The 630 gg/L reported at TW4-22 for the fourth quarter of 2008 is
within the pre-third quarter range of concentrations measured at this well
Continued pumping of TW4-19 TW4-20 MW-4 and MW-26 TW4-15 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
12
The chloroform concentration at downgradient well TW4-6 decreased from 39 to
37 gg/L Although fluctuations in concentrations have occurred this well has likely
remained outside the chloroform plume due to combination of slow rates of
downgradient chloroform migration in this area due to low permeability conditions and
the effects of upgradient chloroform removal by pumping and 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
