1.0 INTRODUCTION
The presence of chloroform was initially identified in groundwater at the White Mesa
Mill (the "Mill") as a result of split sampling performed in May 1999. The discovery
resulted in the issuance of State of Utah Notice of Violation ("NOV") and Groundwater
Corrective Action Order ("CAO") State of Utah Department of Environmental Quality
("UDEQ") Docket No. UGQ-20-01, which required that Denison Mines (USA) Corp.
("DUSA") submit a Contamination Investigation Plan and Report pursuant to the
provisions ofUAC R317-6-6.15(D).
The frequency of chloroform sampling, which was initially performed on a monthly
basis, was modified on November 8, 2003. Since that time all chloroform contaminant
investigation wells have been sampled on a quarterly basis.
This is the Quarterly Chloroform Monitoring Report for the first quarter of 2012 as
required under the NOV and CAO. This Report also includes the Operations Report for
the Long Term Pump Test at MW-4, TW4-19, MW-26 (previously referred to as TW4-
15), TW4-20, and TW4-4 for the quarter.
2.0 CHLOROFORM MONITORING
2.1 Samples and Measurements Taken During the Quarter
A map showing the location of all groundwater monitoring wells, piezometers, existing
wells, temporary chloroform contaminant investigation wells and temporary nitrate
investigation wells is attached under Tab A. Chloroform samples and measurements
taken during this reporting period (January through March), are discussed in the
remainder of this section.
2.1.1 TW 4-27
Installation of the new perched groundwater monitoring well, TW4-27, was completed on
November 8, 2011, as required by the May 26, 2011 Division of Radiation Control
("DRC") Request for Additional Information ("RFI"), and as delineated in the Final
Denison Work Plan and Schedule to Drill and Install Well TW4-27 (the "Plan"),
submitted to DRC on October 3,2011.
Per section 1.2 of the Plan, water level and chloroform concentration data will be
collected from existing wells, as well as TW4-27, to determine if TW4-27 satisfies the
stipulated criteria. TW 4-27 will satisfy the stipulated criteria if, the 70 ug/L chloroform
isoconcentration line remains hydraulically up gradient of TW4-27, and groundwater
contour lines show that TW 4-27 is hydraulically downgradient of TW 4-4 and TW 4-6.
In addition to the criteria in section 1.2, section 1.3 of the Plan states that if water level
data from TW4-27 indicates that the water level at TW4-14 is anom~lous, TW4-14 will
be abandoned, with the approval of the Executive Secretary. The water level at TW 4-14
1
N :\Required Reports\Chloroform Quarterly Monitoring Report\20 12 Q 1 \20 12_ Q 1 Chloroform _ Report_text.doc
will be considered anomalous if the water level at TW4-27 is comparable to the water
level at TW 4-6.
TW 4-27 was installed hydraulically downgradient of wells TW 4-4 and TW 4-6 to ensure
the chloroform plume is bounded. The estimated perched water elevation at TW4-27,
indicates that TW4-27 is located downgradient of TW4-6 and TW4-26, and TW4-14 is
located downgradient of TW4-4 and TW4-6. TW4-14 and TW4-27 are therefore properly
located to bound the chloroform plume to the east of TW4-4, TW4-6, and TW4-26.
The first quarter of 2012 marks the first sampling event for TW4-27. Per the
requirements of the Plan, quarterly water level measurements and sampling will continue
during the next regularly scheduled chloroform sampling event. A determination of
whether or not the criteria in paragraph 1.2 of the Plan have been satisfied with the
addition of TW 4-27 will be made after receipt of two quarters of water level and
chloroform data. A decision whether or not to abandon TW 4-14 will also be made by
Denison and the Executive Secretary at that time.

Table 1 provides an overview of all wells sampled during the quarter, along with the date
samples were collected from each well, and the date(s) which analytical data were
received from the contract laboratory. Table 1 also identifies equipment rinsate samples
collected, as well as sample numbers associated with the deionized field blank ("DIFB")
and any required duplicates.
As indicated in Table 1, chloroform monitoring was performed in all of the required
chloroform monitoring wells.
2.1.3 Parameters Analyzed
Wells sampled during this reporting period were analyzed for the following constituents:
• Chloroform
• Chloromethane
2
N:\Required Reports\Chlorofonn Quarterly Monitoring Report\20 12 Q 1 \20 12_ Q 1 Chlorofonn _Report _text. doc
• Carbon tetrachloride
• Methylene chloride
• Chloride
• Nitrate plus Nitrite as Nitrogen
Use of analytical methods is consistent with the requirements of the Chloroform
Investigation Monitoring Quality Assurance Program (the "Chloroform QAP") attached
as Appendix A to the White Mesa Uranium Mill Groundwater Monitoring Quality
Assurance Plan ("QAP").
2.1.4 Groundwater Head Monitoring
Depth to groundwater was measured in the following wells and/or piezometers, pursuant
to Part I.E.3 of the Groundwater Discharge Permit (the "GWDP"):
• The quarterly groundwater compliance monitoring wells.
• Existing monitoring well MW -4 and all of the temporary chloroform investigation
wells.
• Piezometers -P-l, P-2, P-3, P-4 and P-5.
• MW-20 and MW-22.
• Nitrate monitoring wells.
• In addition to the above, depth to water measurements are routinely observed in
conjunction with sampling events for all wells sampled during quarterly and
accelerated efforts, regardless of the sampling purpose.
• The DR piezometers which were installed during the Southwest Hydrologic
Investigation.
In addition, weekly and monthly depth to groundwater measurements were taken in MW-
4, MW-26, TW4-19, TW4-20, and TW4-4, as part of the long term pumping test for
MW-4.
2.2 Sampling Methodology and Equipment and Decontamination Procedures
DUSA completed, and transmitted to UDEQ on May 25, 2006, a revised QAP for
sampling under the Mill's Groundwater Discharge Permit ("GWDP"). While the water
sampling conducted for chloroform investigation purposes has conformed to 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 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
Quality Assurance ("QA") procedures in the form of the Chloroform QAP. The
Chloroform QAP describes the needs of the chloroform investigation program where they
differ from the Groundwater QAP. On June 20, 2009 the Chloroform QAP was modified
to require that the quarterly chloroform reports include additional items specific to
DUSA's ongoing pump testing and chloroform capture efforts.
3
N:\Required Reports\Chlorofonn Quarterly Monitoring Report\20 12 Q 1 \20 12_ Q 1 Chlorofonn _Report _text. doc
The sampling methodology, equipment and decontamination procedures that were
performed for the chloroform contaminant investigation, as summarized below, are
consistent with the QAP and the Chloroform QAP.
2.2.1 Well Purging and Depth to Groundwater
A list of the wells in order of increasing chloroform contamination is generated quarterly.
The order for purging is thus established. The list is included with the Field Data
Worksheets under Tab B. Mill personnel start purging with all of the non-detect wells
and then move to the more contaminated wells in order of chloroform contamination.
Before leaving the Mill office, the portable pump and hose are rinsed with deionized
("DI") water. A rinsate blank sample is collected at the beginning of each day prior to
the first use of the pump. Mill personnel then proceed to the first well which is the well
with the lowest concentration of chloroform based on the previous quarter's sampling
results. Well depth measurements are taken and the two casing volumes are calculated
for those wells which do not have a dedicated pump (measurements are made using the
same instrument used for the monitoring wells under the Mill's GWDP). If the well has a
dedicated pump, it is pumped on a set schedule per the remediation plan and is
considered sufficiently evacuated to immediately collect a sample; however, if a pumping
well has been out of service for 48 hours or more, DUSA will follow the purging
requirements outlined in Section 6.2.7( d) (v) of the QAP. The dedicated pump is used to
collect parameters and to collect the samples as described below. If the well does not
have a dedicated pump, a Grundfos pump (9 -10 gpm pump) is then lowered to the
screened interval in the well and purging is started. The purge rate is measured for the
well by using a calibrated 5 gallon bucket. The purging of the well is completed per
Section 6.2.5 of the QAP. In wells where the portable pump is used, a disposable bailer is
used to collect the samples the day following purging activities. After each use, the
portable pump is decontaminated prior to reuse at the next sample location. This purging
process is repeated at each well location moving from least contaminated to the most
contaminated well. All wells are capped and secured prior to leaving the sampling
location.
Wells with dedicated pumps are sampled when the pump is in the pumping mode. If the
pump is not pumping at the time of sampling, it is manually switched on by the Mill
Personnel. The well is pumped for approximately 5 to 10 minutes prior to the collection
of the field parameters. Per the approved QAP, one set of parameters is collected.
Samples are collected following the measurement of one set of field parameters. The
pump is turned off and allowed to resume its timed schedule.
2.2.2 Sample Collection
Samples are collected as described above. In all cases, on days when samples will be
collected, a cooler with 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 then
4
N:\Required Reports\Chloroform Quarterly Monitoring Report\20 12 Q 1 \2012_ Q 1 Chloroform _Report_text. doc
outfitted with rubber gloves. Chloroform investigation samples are collected by means of
disposable bailers.
Mill personnel use a disposable bailer to sample each well that does not have a dedicated
pump. 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:
• Volatile Organic Compound ("VOC") samples are collected first. This sample
consists of three 40 ml vials provided by the Analytical Laboratory. The VOC
sample is not filtered and is preserved with HCI;
• A sample for nitrate/nitrite is then collected. This sample consists of one 250 ml.
bottle which is provided by the Analytical Laboratory. The nitrate/nitrite sample
is also not filtered and is preserved with H2S04;
• A sample for chloride is then collected. This sample consists of one 500 ml.
bottle which is provided by the Analytical Laboratory. The chloride sample is
also not filtered and is not chemically preserved.
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 ice. The well is then recapped and
Mill personnel proceed to the next well.
2.3 Field Data
Attached under Tab B are copies of all Field Data Worksheets that were completed
during the quarter for the chloroform contaminant investigation monitoring wells
identified in paragraph 2.1.1 above, and Table 1.
2.4 Depth to Groundwater Data and Water Table Contour Map
Attached under Tab C are copies of the Depth to Water Sheets for the weekly monitoring
of MW-4, MW-26, TW4-19, TW4-20, and TW4-4, as well as the monthly depth to
groundwater data for chloroform contaminant investigation wells measured during the
quarter. Depth to groundwater measurements which were utilized for groundwater
contours are included on the Quarterly Depth to Water Worksheet at Tab D of this report,
along with the kriged groundwater contour map for the current quarter generated from
this data. A copy of the kriged groundwater contour map generated from the fourth
quarter 2011 data is provided under Tab E.

2.5 Laboratory Results
2.5.1 Copy of Laboratory Results
All analytical results were provided by Energy Laboratories ("EL"). Table 1 lists the
dates when analytical results were reported to the QA Manager for each well or other
sample.
Results from analysis of samples collected for the quarter chloroform contaminant
investigation are provided under Tab H of this Report. Also included under Tab Hare
the results of analyses for duplicate samples, the DIFB, and rinsate samples for this
sampling effort, as identified in Table 1, as well as results for trip blank analyses required
by the Chloroform QAP.
2.5.2 Regulatory Framework
As discussed in Section 1.0, above, the NOV and requirements of the CAO triggered a
series of actions on DUSA's part. In addition to the monitoring program, DUSA has
equipped five wells with pumps to recover impacted groundwater, and has initiated
recovery of chloroform from the perched zone.
Sections 4 and 5, below, interpret the groundwater level and flow information,
contaminant analytical results, and pump test data to assess effectiveness of DUSA's
chloroform capture program.
3.0 QUALITY ASSURANCE AND DAT A VALIDATION
The QA Manager performed a QAlQuality Control ("QC") review to confirm compliance
of the monitoring program with requirements of the QAP. As required in the QAP, data
QA includes preparation and analysis of QC samples in the field, review of field
procedures, an analyte completeness review, and QC review of laboratory methods and
data. Identification of field QC samples collected and analyzed is provided in Section
3.1. Discussion of adherence to Mill sampling Standard Operating Procedures ("SOPs")
is provided in Section 3.2. Analytical completeness review results are provided in
Section 3.3. The steps and tests applied to check laboratory data QAlQC are discussed in
Sections 3.4.4 through 3.4.9 below.
The analytical laboratory has provided summary reports of the analytical quality QAlQC
measurements necessary to maintain conformance with National Environmental
Laboratory Accreditation Conference ("NELAC") certification and reporting protocol.
The Analytical Laboratory QAlQC Summary Reports, including copies of the Mill's
Chain of Custody and Analytical Request Record forms for each set of Analytical
Results, follow the analytical results under Tab H. Results of review of the laboratory
QAlQC information are provided under Tab I and are discussed in Section 3.4, below.
6
N:\Required Reports\Chloroform Quarterly Monitoring Report\20 12 Q 1 \20 12_ Q 1 Chloroform_Report _text. doc
3.1 Field QC Samples
The following QC samples were generated by Mill personnel and submitted to the
analytical laboratory in order to assess the quality of data resulting from the field
sampling program.
Field QC samples for the chloroform investigation program consist of one field duplicate
sample for each 20 samples, a trip blank for each shipped cooler which contains VOCs,
one DIFB and rinsate samples.
During this quarter, two duplicate samples were collected as indicated in Table 1. The
duplicates were sent blind to the analytical laboratory and analyzed ' for the same
parameters as the chloroform wells.
Two trip blanks were provided by Energy Laboratories and returned with the quarterly
chloroform monitoring samples.
Four rinsate blank samples were collected as indicated on Table 1. Rinsate samples were
labeled with the name of the subsequently purged well with a terminal letter "R" added
(e.g. TW 4-7R). The results of these analyses are included with the routine analyses under
TabH.
In addition, one DIFB, while not required by the Chloroform QAP, was collected and
analyzed for the same constituents as the well samples and rinsate blank samples.
3.2 Adherence to Mill Sampling SOPs
On a review of adherence by Mill personnel to the existing sampling SOPs, the QA
Manager observed that QAlQC requirements established in the QAP and Chloroform
QAP were being adhered to and that the SOPs were implemented, except as described
below.
One site procedure requiring clarification was noted during the QA Manager's review of
the field data. As previously stated, a list of the wells in order of increasing chloroform
contamination (based on the previous quarter's data) is generated quarterly prior to the
next quarter's sampling to determine the order for purging prior to sampling. Consistent
with the approved QAP, each quarterly event begins with purging of the wells from the
least affected to the most affected based on the previous quarter's data. Although purging
follows this order, the sampling order may deviate slightly from the generated list. This
practice does not affect the samples for these reasons: any wells sampled in slightly
different order had either dedicated pumps or were sampled via a disposable bailer. This
practice does not affect the quality or usability of the data as there is no cross-
contamination resulting from sampling order. DUSA intends to propose modified
language to clarify this practice in the next revision of the QAP.

N:\Required Reports\Chloroform Quarterly Monitoring Report\20 12 Q 1 \20 12_ Q 1 Chloroform_Report _text. doc
3.3 Analyte Completeness Review
All analyses required by the GWDP for chloroform monitoring for the period were
performed.
3.4 Data Validation
The QAP and GWDP identify the data validation steps and data QC checks required for
the chloroform monitoring program. Consistent with these requirements, the QA
Manager performed the following evaluations: a field data QAlQC evaluation, a holding
time check, a receipt temperature check, an analytical method check, a reporting limit
evaluation, a trip blank check, a QAlQC evaluation of sample duplicates, a QC Control
Limit check for analyses and blanks including the DIFB and a rinsate sample check.
Each evaluation is discussed in the following sections. Data check tables indicating the
results of each test are provided under Tab I.
3.4.1 Field Data QAlQC Evaluation
The QA Manager performs a review of all field recorded parameters to assess their
adherence with QAP requirements. The assessment involved review of two sources of
information: the Field Data Sheets and the Quarterly Depth to Water summary sheet.
Review of the Field Data Sheets addresses well purging volumes and stability of five
parameters: conductance, pH, temperature, redox potential, and turbidity. Review of the
Depth to Water data confirms that all depth measurements used for development of
groundwater contour maps were conducted within a five-day period as indicated by the
measurement dates in the summary sheet under Tab D. The results of this quarter's
review offield data are provided under Tab I.
Based upon this review, all non-pumping wells conformed to the QAP requirement to
evacuate two well casing volumes before sampling except TW4-1, TW4-2, TW4-3,
TW4-6, TW4-7, TW4-10, TW4-11, TW4-13, TW4-14, TW4-22, TW4-26, and TW4-27.
All of these wells were pumped to dryness before two casing volumes were evacuated
and as such the requirement to purge two casing volumes does not apply. TW4-16 was
purged to dryness after two casing volumes were removed. In each case, representative
samples of formation water were collected after the wells were allowed to recover.
During review of the field data sheets, it was observed that sampling personnel
consistently recorded depth to water to the nearest 0.01 foot.
All field parameters for all wells were within the required Relative Percent Difference
("RPD") (other than the wells that were pumped to dryness and the wells which are
continually pumped, for which this requirement does not apply), except as follows.
The review of the field sheets . for compliance with QAP requirements resulted in the
observations noted below. The requirements in Section 6.2.7 of the QAP specifically
state that field parameters must have stabilized to within 10% over at last 2 consecutive
measurements. During this quarter's sampling event, all field parameters were stabilized
within 10%.
8
N:\Required Reports\Chloroform Quarterly Monitoring Report\20 I 2 Q I \20 12_ Q I Chloroform_Report _text. doc
The QAP states that turbidity should be less than 5 Nephelometric Turbidity Units
("NTU") prior to sampling unless the well is characterized by water that has a higher
turbidity.
Twenty-six turbidity measurements exceeded the QAP's 5 NTU goal. Of the twenty-six
samples, thirteen samples were taken after the well had been pumped to dryness. The
QAP does not require that turbidity measurements be less than 5 NTU prior to sampling.
As such, the noted observations regarding turbidity measurements less than 5 NTU below
are included for information purposes only.
3.4.2 Holding Time Evaluation
QAP Table 1 identifies the method holding times for each suite of parameters. Sample
holding time checks are provided in Tab I. All samples were received and analyzed
within the required holding time.
3.4.3 Receipt Temperature Evaluation
Chain of Custody sheets were reviewed to confirm compliance with the QAP requirement
which specifies that samples be received at 6°C or lower. Sample temperatures checks
are provided in Tab I. All samples were received within the required temperature limit.
3.4.4 Analytical Method Checklist
All analytical methods reported by the laboratory were checked against the required
methods enumerated in the Chloroform QAP. Analytical method checks are provided in
Tab I. All methods were consistent with the requirements of the Chloroform QAP.
·3.4.5 Reporting Limit Evaluation
All analytical method reporting limits reported by the laboratory were checked against
the reporting limits enumerated in the Chloroform QAP. Reporting Limit Checks are
provided under Tab I. All analytes were measured and reported to the required reporting
limits, except 24 sets (22 samples and 2 duplicates) of sample results had the reporting
limit raised for at least one analyte due to matrix interference and/or sample dilution. In
all cases the reported value for the analyte was higher than the increased detection limit.
3.4.6 Trip Blank Evaluation
All trip blank results were reviewed to identify any VOC contamination resulting from
transport of the samples. Trip blank checks are provided in Tab I. All trip blank results
were less than the reporting limit for all VOCs.
3.4.7 QAlQC Evaluation for Sample Duplicates
Section 9.1.4 a) of the QAP states that RPDs will be calculated for the comparison of
duplicate and original field samples. The QAP acceptance limits for RPDs between the
duplicate and original field sample is less than or equal to 20% unless the measured
9
N :\Required Reports\Chloroform Quarterly Monitoring Report\20 12 Q 1 \20 12_ Q 1 Chloroform_Report _text. doc
results (described as activities in the QAP) are less than 5 times the required detection
limit. This standard is based on the EP A Contract Laboratory Program National
Functional Guidelines for Inorganic Data Review, February 1994, 9240.1-05-01 as cited
in the QAP. The RPDs are calculated for all duplicate pairs for all analytes regardless of
whether or not the reported concentrations are greater than 5 times the required detection
limits; however, data will be considered noncompliant only when the results are greater
than 5 times the reported detection limit and the RPD is greater than 20%. Theadditional
duplicate information is provided for information purposes.
All analytical results for the sample/duplicate pairs were within the 20% acceptance
limits. All results of the RPD test are provided in Tab I.
3.4.8 Rinsate Sample Check
Rinsate blank sample checks are provided in Tab I.
Chloroform and Chloride
A review of the analytical results reported for rinsate blank samples indicated that one of
the rinsate blank samples contained chloroform. A DIFB was analyzed and the results
indicated that it contained chloride. A comparison of the rinsate blank sample
concentration levels to the QAP requirements -that iinsate sample concentrations be one
order of magnitude lower than that of the actual well -indicated that the rinsate blank
sample with a detection of chloroform did not meet this criterion. The rinsate blank
reported a detection of chloroform at 1.0 ug/L while the parent sample did not report a
detection for chloroform. The fact that the rinsate blank had a detection while the parent
sample did not indicates that the contamination is resulting from the DI water used to
make the rinsate blank.
The QAP requirement for rinsate concentrations, however, is irrelevant and inappropriate
for the rinsate blank sample data collected during the chloroform sampling because
rinsate blank samples are collected from the decontaminated portable pump used for well
purging, and the pump is not used for sample collection. As stated in Section 2.2.1, wells
that do not have a dedicated pump are purged using a portable pump. In wells where the
portable pump is used for purging, a disposable bailer is used to collect the samples the
day following purging activities. That is, in no case is the rinsate sample actually
indicative of contamination or carryover.
Based on the investigation into the source of chloroform, DUSA believes that the
potential source for the chloroform present in the rinsate blanks has been identified.
DUSA believes the chloroform and chloride contamination in the DI water is most likely
the result of chlorination of the intake water used for the D I system. The chloroform and
chloride is most likely the result of the chlorination of the potable water at the Mill which
is subsequently fed to the DI system. The chlorine added to the potable water used for
the DI system intake reacts with the naturally occurring organic and inorganic materials
in the water and produces chloroform and chloride.

Corrective actions for this issue are described in Section 6.1.
3.4.9 Other Laboratory QAlQC
Section 9.2 of the QAP requires that the laboratory's QAlQC Manager check the
following items in developing data reports: (1) sample preparation information is correct
and complete, (2) analysis information is correct and complete, (3) appropriate analytical
laboratory procedures are followed, (4) analytical results are correct and complete, (5)
QC samples are within established control limits, (6) blanks are within QC limits, (7)
special sample preparation and analytical requirements have been met, and (8)
documentation is complete. In addition to other laboratory checks described above,
DUSA's QA Manager rechecks QC samples and blanks (items (5) and (6)) to confirm
that the percent recovery for spikes and the relative percent difference for spike
duplicates are within the method-specified acceptance limits, or that the case narrative
sufficiently explains any deviation from these limits. Results of this quantitative check
are provided in Tab I.
All lab QAlQC results met these specified acceptance limits except as noted below.
The QAP Section 8.1.2 requires that a Matrix Spike/Matrix Spike Duplicate
("MS/MSD") (referred to as Duplicate Spike [Matrix spike] in the QAP) pair be analyzed
with each analytical batch. The QAP does not specify acceptance limits for the MS/MSD
pair, and the QAP does not specify that the MS/MSD pair be prepared on DUSA samples
only. Acceptance limits for MS/MSDs are set by the laboratories. The review of the
information provided by the laboratories in the data packages verified that the QAP
requirement to analyze an MS/MSD pair with each analytical batch was met. While the
QAP does not requIre it, the recoveries were reviewed for compliance with the laboratory
established acceptance limits. The QAP does not require this level of review, and the
results of this review are provided for information only.
The information from the Laboratory QAlQC Summary Reports indicates that the
MS/MSDs recoveries and the associated RPDs for all quarterly chloroform samples are
within acceptable laboratory limits for all regulated compounds except as indicated in
Tab I. The recoveries, which are outside of the laboratory established acceptance limits,
do not affect the quality or usability of the data because the recoveries outside of the
acceptance limits are indicative of matrix interference. The QAP requirement to analyze a
MS/MSD pair with each analytical batch was met and as such the data are compliant with
the QAP.
The QAP specifies that surrogate compounds shall be employed for all organic analyses,
but the QAP does not specify acceptance limits for surrogate recoveries. The analytical
data associated with the routine quarterly sampling met the requirement specified in the
QAP. The information from the Laboratory QAlQC Summary Reports indicates that the
surrogate recoveries for all quarterly chloroform samples were within acceptable
laboratory limits for all surrogate compounds except as indicated in Tab I. Three
surrogate recoveries were above the laboratory established acceptance limits or had a
high recovery, indicating a high bias to the individual sample results. A high bias means
that reported results may be higher than the actual results. There is no effect on the
11
N:\Required Reports\Chloroform Quarterly Monitoring Report\20 12 Q 1 \20 12_ Q 1 Chloroform_Report _text. doc
quality or usability of the data because there are multiple surrogates added to each sample
and all other surrogates were within limits. Furthermore, there are no QAP requirements
for surrogate recoveries.
The information from the Laboratory QAlQC Summary Reports indicates that all LCS
recoveries were within acceptable laboratory limits for all LCS compounds.
4.0 INTERPRETATION OF DATA
4.1 Interpretation of Groundwater Levels, Gradients and Flow Directions.
4.1.1 Current Site Groundwater Contour Map
As stated above, a listing of groundwater level readings for the current quarter (shown as
depth to groundwater in feet) is included under Tab D. The data from this tab has been
interpreted (kriged) and plotted in a water table contour map, provided under the same
tab.
Also included under Tab D is a groundwater contour map of the Mill site and a more
detailed map of a portion of the Mill site where the chloroform pumping wells are
located, in each case with hand-drawn stream tubes, depicting hydraulic capture from the
pumpIng.
The water level contour maps indicate that perched water flow ranges from generally
southwesterly beneath the Mill site and tailings cells to generally southerly along the
eastern and western margins of White Mesa. Perched water mounding associated with the
wildlife ponds locally changes the flow patterns. For example, northeast of the Mill site,
mounding associated with wildlife ponds results in locally northerly flow near MW -19.
Flow directions are also locally influenced by pumping at MW-4, MW-26, TW4-4, TW4-
19, and TW4-20. Significant cones of depression have formed in the vicinity of all
pumping wells except TW4-4, which began pumping in the first quarter of2010.
Although pumping at TW4-4 has depressed the water table in the vicinity of TW4-4, a
well-defined cone of depression is not evident. The lack of a well-defined cone of
depression likely results from 1) variable permeability conditions in the vicinity of TW 4-
4, and 2) persistent relatively low water levels at adjacent well TW 4-14.
Changes in water levels at wells immediately south of TW4-4 resulting from TW4-4
pumping are expected to be muted because TW 4-4 is located at a transition from
relatively high to relatively low permeability conditions south (downgradient) of TW 4-4.
The permeability of the perched zone at TW4-6 and TW4-26 is approximately two orders
of magnitude lower than at TW 4-4. Any drawdown of water levels at wells immediately
south of TW 4-4 resulting from TW 4-4 pumping is also difficult to determine because of a
general, long-term increase in water levels in this area. Water levels at TW4-4 and TW4-
6 increased by nearly 2.7 and 2.9 feet, respectively, between the fourth quarter of 2007
and the fourth quarter of 2009 Gust prior to TW 4-4 pumping) at rates of approximately
1.2 feet/year and 1.3 feet/year, respectively. However, the increase in water level at TW4-
12
N:\Required Reports\Chloroform Quarterly Monitoring Report\20 12 Q I \20 12_ Q 1 Chloroform_Report _text. doc
6 has been reduced since the start of pumping at TW4-4 (first quarter of 2010) to less
than 0.5 feet/year suggesting that TW4-6 is within the hydraulic influence of TW4-4.
The lack of a well-defined cone of depression at TW 4-4 is also influenced by the
persistent, relatively low water level at non-pumping well TW 4-14, located east of TW 4-
4 and TW4-6. For the current quarter, the water level at TW4-14 (approximately 5526
feet above mean sea level [ft amsl]) is approximately 13 feet lower than the water level
at TW4-6 (approximately 5539 ft amsl) and approximately 17 feet lower than at TW4-4
(approximately 5543 ft amsl) even though TW4-4 is pumping.
Recently installed well TW4-27 (located south of TW4-14) has a static water level of
approximately 5525 ft amsl, similar to TW4-14. TW4-27 was positioned at a location
considered likely to detect any chloroform present and/or to bound the chloroform plume
to the southeast and east of TW 4-4 and TW 4-6.
Prior to the installation of TW4-27, the persistently low water level at TW4-14 was
considered anomalous because it appeared to be downgradient of all three wells TW4-4,
TW4-6, and TW4-26, yet there is no chloroform at TW4-14. Chloroform had apparently
migrated from TW4-4 to TW4-6 and from TW4-6 to TW4-26 which suggested that
TW 4-26 was actually downgradient of TW 4-6, and TW 4-6 was actually downgradient of
TW 4-4, regardless of the flow direction implied by the low water level at TW 4-14. The
water level at TW4-26 (5538.2 feet amsl) is, however, lower than water levels at adjacent
wells TW4-6 (5538.7 feet amsl), and TW4-23 (5542.6 feet amsl)
Hydraulic tests conducted in November 2011 indicate that the permeability at TW4-27 is
an order of magnitude lower than at TW 4-6 and three orders of magnitude lower than at
TW4-4. The similar water levels at TW4-14 and TW4-27, and the low permeability
estimate at TW4-27 suggest that both wells are completed in materials having lower
permeability than nearby wells. The low permeability condition likely reduces the rate of
long-term water level increase at TW4-14 and TW4-27 compared to nearby wells,
yielding water levels that appear anomalously low. The low permeability condition is
expected to retard the transport of chloroform to TW4-14 and TW4-27 (compared to
nearby wells). As will be discussed in Section 4.2.3, first quarter, 2012 chloroform
concentrations at TW4-26 and TW4-27 are similar (7 ug/L at TW4-26 and 9 ug/L at
TW 4-27) and both are outside the chloroform plume.
4.1.2 Comparison of Current Groundwater Contour Maps to Groundwater
Contour Maps for Previous Quarter
The groundwater contour maps for the Mill site for the fourth quarter of 2011, as
submitted with the Chloroform Monitoring Report for the fourth quarter of 2011, are
attached under Tab E.
A comparison of the water table contour maps for the current (first) quarter of2012 to the
water table contour maps for the previous quarter (fourth quarter of 2011) indicates
similar patterns of drawdown related to pumping of MW -4, MW -26, TW 4-4, TW 4-19
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. As discussed in Section
13
N:\Required Reports\Chloroform Quarterly Monitoring Report\20 12 Q 1 \20 12_ Q 1 Chloroform_Report _text. doc
4.1.1, pumping at TW4-4, which began in the first quarter of 2010, has depressed the
water table near TW4-4, but a well-defined cone of depression is not yet evident, likely
due to variable permeability conditions near TW 4-4 and the low water level at adjacent
well TW4-14.
Reported increases in water levels of approximately 7 feet occurred in recently installed
well TW4-27 and of approximately 5 feet occurred in well MW-37. The increase in water
level in TW4-27 is due to the fact that the water level in that well was measured in the
fourth quarter of 2011 immediately following development activities prior to complete
stabilization of the water level in the well. Reported increases in water· levels of
approximately 9 feet occurred in pumping well TW4-20 and of approximately 8 feet
occurred in pumping well MW-26. The water level changes at pumping wells MW-4,
TW 4-4, and TW 4-19 were less than 5 feet.
Water level fluctuations at pumping wells MW-4, MW-26, TW4-4, 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 decrease (increase in drawdown) of approximately 1
foot occurred in well TW 4-4 and the largest increase (decrease in drawdown), of
approximately 9 feet, occurred in well TW4-20. The reported water level at well MW-37
during the current quarter is similar to the reported third quarter, 2011 water level, and
the water level at TW4-27 is similar to that reported at the time of installation. Reported
water levels at both wells in the previous quarter were lower than typical.

chloroform contaminant investigation monitor well over time.
4.1.4 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.
4.1.5 Evaluation of the Effectiveness of Hydraulic Capture
Perched water containing chloroform has been removed from the subsurface by pumping
MW-4, MW-26, TW4-4, TW4-19, and TW4-20. The primary purpose of the pumping is
to reduce total chloroform mass in the perched zone as rapidly as is practical. Pumping
wells up gradient of TW 4-4 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 these 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. TW 4-4 is located in a downgradient area having relatively high chloroform
concentrations but relatively small saturated thickness, and at a transition from relatively
high to relatively low permeability conditions downgradient of TW 4-4. As with the other
14
N:\Required Reports\Chloroform Quarterly Monitoring Report\20 12 Q 1 \2012_ Q 1 Chloroform_Report _text doc
pumping wells, pumping TW 4-4 helps to reduce the rate of chloroform migration in
downgradient portions of the plume.
The impact of pumping is indicated by the water level contour maps attached under Tabs
D and E. Cones of depression have developed in the vicinity of MW -4, MW -26, TW 4-
19, and TW4-20 which continue to remove significant quantities of chloroform from the
perched zone. The water level contour maps indicate effective capture of water
containing high chloroform concentrations in the vicinities of these pumping wells.
Overall, the combined capture of MW-4, MW-26, TW4-19, and TW4-20 has not changed
significantly (but has decreased slightly) since the last quarter. As noted in Section 4.1.2,
decreases in water levels (increases in drawdown) of approximately 1 foot occurred at
TW4-4, and an increase in water level (decrease in drawdown) of approximately 9 feet
occurred at TW4-20. The decrease in drawdown at TW4-20 has slightly decreased the
apparent capture zone of this well compared to the previous quarter. As discussed in
Section 4.1.1, the drawdown associated with TW 4-4 is likely less apparent due to
variable permeability conditions near TW4-4 and the low water level at adjacent well
TW4-14.
Chloroform concentrations exceeding 70 J.lg/L have occurred in the past at some
locations downgradient of pumping wells (for example, at TW4-6, located immediately
south of TW 4-4), where the lower permeability and relatively small saturated thickness
of the perched zone significantly limits the rate at which chloroform mass can be
removed by pumping. By removing mass and reducing hydraulic gradients, thereby
reducing the rate of downgradient chloroform migration, and allowing natural attenuation
to be more effective, pumping at the productive, upgradient locations has a beneficial
effect on this downgradient chloroform. Pumping at TW 4-4 was implemented during the
first quarter of 2010 to improve capture in this downgradient area to the extent allowable
by the lower productivity conditions presumed to exist in this area. The beneficial effect
of pumping TW 4-4 is demonstrated by the decrease in chloroform concentrations at
TW4-6 from 1000 J.lg/L to 38 J.lg/L, and at TW4-26 from 13 J.lg/L to 7 J.lg/L since
pumping began at TW 4-4 (although concentrations at these wells have been increasing
slightly since reaching lows in the second quarter of 2011). Concentrations at these wells
have decreased substantially even though they do not unambiguously appear to be within
the hydraulic capture of TW 4-4. As discussed in Section 4.1.1, however, the decrease in
the long-term rate of water level rise at TW 4-6 since pumping began at TW 4-4 does
suggest that TW4-6 is within the hydraulic influence of TW4-4. Regardless of whether
TW 4-6 can be demonstrated to be within hydraulic capture of TW 4-4, pumping TW 4-4
reduces chloroform migration to TW4-6 and TW4-26 by the mechanisms discussed
above.

Attached under Tab K are tables summarizing values for all required parameters,
chloride, nitrate/nitrite, carbon tetrachloride, chloroform, chloromethane, and methylene
chloride, for each well over time.
Attached under Tab L are graphs showing chloroform concentration trends in each
monitor well over time.
4.2.3 Interpretation of Analytical Data
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 20% in the following
wells compared to last quarter: MW-26, TW4-6, TW4-20, and TW4-26;
b) Chloroform concentrations have decreased by more than 20% in the following
wells compared to last quarter: TW4-2, TW4-10, TW4-11, TW4-19, and TW4-
22;
c) Chloroform concentrations have remained within 20% in the following wells
compared to last quarter: MW-4, TW4-1, TW4-4, TW4-5, TW4-7, TW4-18, and
TW4-21;
d) MW-32, TW4-3, TW4-8, TW4-9, TW4-12, TW4-13, TW4-14, TW4-16, TW4-
23, and TW4-25 remained non-detect; and
e) Chloroform concentrations at TW 4-24 decreased from 1.2 Jlg/L to non-detect
As indicated, chloroform concentrations at many of the wells with detected chloroform
were within 20% of the values reported for the wells during the previous quarter,
suggesting that variations are within the range typical for sampling and analytical error.
Wells TW4-2, TW4-6, TW4-10, TW4-11, TW4-19, TW4-20, TW4-22, TW4-26, and
MW-26 had changes in concentration greater than 20%. Of the latter, MW-26, TW4-19,
and TW4-20 are pumping wells. TW4-2 and TW4-11 are located adjacent to pumping
well MW-4; TW4-6 is located adjacent to pumping well TW4-4; TW4-10 is located
adjacent to pumping well MW -26; and TW 4-22 is adjacent to pumping well TW 4-20.
Fluctuations in concentrations at pumping wells and wells adjacent to pumping wells
likely result in part from changes in pumping. The change in concentration at TW4-26
from 5.2 Jlg/L to 7 Jlg/L is likely due to its location near the downgradient edge of the
plume where changes in upgradient pumping are expected to affect concentrations. It
should be noted that although the concentration at TW4-26 has increased slightly since
last quarter it is still lower than the 13 Jlg/L measured at TW4-26 prior to commencement
of pumping in TW4-4.
16
N:\Required Reports\Chloroform Quarterly Monitoring Report\20 12 Q 1 \20 12_ Q 1 Chloroform _Report_text. doc
Pumping well TW 4-20 had the highest detected chloroform concentration. Since the last
quarter, the chloroform concentration in TW4-20 increased from 7,900 /-lg/L to 11,000
/-lg/L, the concentration in adjacent pumping well TW4-19 decreased from 2,200 /-lg/L to
690 /-lg/L, the concentration in nearby well TW4-21 increased slightly from 390 to 420
/-lg/L, and the concentration in nearby well TW4-22 decreased from 400 /-lg/L to 200
/-lg/L. Wells TW4-23 and TW4-25 remained non-detect for chloroform, and TW4-24
decreased to non-detect. TW4-24, located west of TW4-22, and TW4-25, located north of
TW4-21, bound the chloroform plume to the west and north. In addition, the
southernmost boundary of the plume remains between TW 4-4 and TW 4-6 (located just
north of southernmost temporary well TW 4-26).
The chloroform concentration in TW 4-6 increased from 21 /-lg/L to 38 /-lg/L. Although
the concentration increased, -TW4-6 remains outside the chloroform plume boundary.
Concentrations at TW 4-6 have, since initiation of pumping of TW 4-4 in the first quarter
of 2010, decreased from 1000 /-lg/L to 38 /-lg/L (although concentrations have been
increasing from a low of 10 /-lg/L in the second quarter of 2011). TW 4-6, installed in the
second quarter of 2000, was the most downgradient temporary perched well prior to
installation of temporary well TW4-23 in 2007 and temporary well TW4-26 in the second
quarter of 2010. TW4-6 remained outside the chloroform plume between the second
quarter of 2000 and the fourth quarter of 2008. TW 4-6 likely remained outside the
chloroform plume during this time 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) natural attenuation. Because TW 4-6
is again outside the plume boundary, TW4-6 and TW4-23 bound the chloroform plume to
the south. TW4-8, TW4-12, TW4-13, TW4-14, and TW4-27 bound the chloroform plume
to the east.
The slow rate of chloroform migration in the vicinity of TW 4-6 is demonstrated by
comparing the rate of increase in chloroform at this well to the rate of increase in the
nearest upgradient well TW 4-4. Concentrations at TW 4-4 increased from non-detect to
more than 2,200 /-lg/L within only 2 quarters whereas 16 quarters were required for
concentrations in TW 4-6 to increase from non-detect to only 81 /-lg/L. This behavior is
consistent with hydraulic tests performed at TW4-4, TW4-6, and TW4-26 during the
third quarter of 2010 that indicate a nearly two-order-of-magnitude decrease in
permeability downgradient of TW 4-4. Chloroform migration rates in the vicinity of well
TW4-26 and new well TW4-27 are also expected to be relatively low due to upgradient
pumping and low permeability conditions.
5.0 LONG TERM PUMP TEST AT MW-4, MW-26, TW4-19, TW4-20, AND
TW4-4 OPERATIONS REPORT
5.1 Introduction
As a part of the investigation of chloroform contamination at the Mill site, DUSA has
been conducting a Long Term Pump Test on MW-4, TW4-19, MW-26, and TW4-20,
and, since January 31, 2010, TW4-4. The purpose of the test is to serve as an interim
action that will remove a significant amount of chloroform-contaminated water while
17
N:\Required Reports\Chloroform Quarterly Monitoring Report\20 12 Q 1 \20 12_ Q 1 Chloroform_Report _text. doc
v .
gathering additional data on hydraulic properties in the area of investigation. The
following information documents the operational activities during the quarter.
5.2 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 MW-26 on August 8, 2003, from
TW4-20 on August 4, 2005, and from TW4-4 on January 31, 2010. Personnel from
Hydro Geo Chern, 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 Chern 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:
• Measurement of water levels at MW-4, TW4-19, MW-26, and TW4-20
and, commencing regularly on March 1, 2010, TW4-4, on a weekly basis,
and at selected temporary wells and permanent monitoring wells on a
monthly basis.
• Measurement of pumping history, including:
pumping rates
total pumped volume
operational and non-operational periods.
• Periodic sampling of pumped water for chloroform and nitrate/nitrite
analysis and other constituents.
5.3 Water Level Measurements
Beginning August 16, 2003, the frequency of water level measurements from MW-4,
MW-26, and TW4-19 was reduced to weekly. From commencement of pumping TW4-
20, and regularly after March 1, 2010 for TW 4-4, water levels in these wells 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, MW-26, TW4-19, TW4-20 and TW4-4 and the monthly
Depth to Water monitoring sheets for all of the chloroform contaminant investigation
wells are included under Tab C. Monthly depth to water measurements for March are
recorded in the Field Data Worksheets included under Tab D.

5.4 Pumping Rates and Volumes
Table 2 summarizes the recovered mass of chloroform by well per quarter and
historically since the inception of the chloroform recovery program for the five currently-
active pumping wells.
All of the pumping wells do not pump continuously, but are on a delay device. The wells
purge for a set amount of time and then shut off to allow the well to recharge. Water
from the pumping wells is transferred to the Cell 1 evaporation pond through a pipeline
installed specifically for that purpose. The pumping rates and volumes for each of the
pumping wells are shown in Table 3. No operational problems were observed with the
well or pumping equipment during the quarter.
5.5 Mass Removed
Chloroform removal was estimated as of the first quarter 2007. Since that estimation the
mass removed by well for each quarter has been compiled in Table 2, indicating that a
total of 596.9 pounds of chloroform have been removed to date.
5.6 Inspections
Denison has submitted an Operations and Maintenance Plan, Chloroform Pumping
System, White Mesa Mill, Blanding, Utah, Revision 2.1 which includes a proposed
weekly inspection form to UDEQ for approval on October 25, 2010. Upon approval of
that plan, the Mill will commence documenting its required inspections of the operational
status of the chloroform pumping wells on the proposed weekly inspection form.
Completed inspections for the quarter, recorded on the approved weekly inspection form,
will be included in future Chloroform reports upon approval by UDEQ. At the time of
the publication of this report, approval of the Operations and Maintenance Plan,

N:\Required Reports\Chloroform Quarterly Monitoring Report\20 12 Q 1 \20 12_ Q 1 Chloroform _ Report_teXt. doc
6.1 Sample/Duplicate Results
Identification and Definition of the Problem
Rinsate and DIFB Chloroform and Chloride Levels
Chloroform is present in the rinsate blanks and chloride is present in the DIFB for this
quarter. To address previous nitrate contamination in the nitrate and chloroform sampling
programs, an additional rinse with 55-gallons of DI water has previously been added to
the decontamination process. DUSA believes that the source for the chloroform present
in the rinsate blanks this quarter appears to be related to the increasing volume of DI
water used in the rinsate process due to the second 55-gallon rinse of the portable pump
with DI water. The chloroform present in the rinsate blanks is present in the DI water and
is not the result of inadequate decontamination of the purging pump. The contamination
in the DI water is most likely the result of chlorination of the intake water (from the
potable water supply source) used for the DI system. At high volume use rates, the DI
system appears to be unable to remove all of the chloride introduced with the DI intake
(supply) water.
Assignment of Responsibility for Investigation of the Problem
The problem is currently under investigation by the QA Manager ..
Investigation and Determination of Cause of the Problem
Rinsate and DIFB Chloroform and Chloride Levels
As discussed above, chloroform is entering the rinsate blanks from the chlorination of the
potable water supply used as a feed to the DI system. The DI system is showing signs of
breakthrough at times of high usage. To address the issue, the QA manager is working
with Mill staff evaluating the best approach to implement upgrades to the DI system to
ensure its ability to support the high volume ofDI water needed for the rinsate process.
Determination of a Corrective Action to Eliminate the Problem
Rinsate and DIFB Chloroform and Chloride Levels
The contamination in the DI water is most likely the result of chlorination of the intake
water used for the DI system. Based on low level detections this quarter, the additional of
a second DI rinse in the process is "stressing" the system and causing chloroform
contamination. By upgrading the system, it will be able to support the high volume of DI
water being pumped through the system.
Assigning and Accepting Responsibility for Implementing the Corrective Action
Rinsate and DIFB Chloroform and Chloride Levels
It will be the joint responsibility of the Director, Compliance and Permitting, and the
Mill's sampling staff to implement the changes and to assess the data to determine if it
has corrected the problems.

Implementing the Corrective Action and Evaluating Effectiveness
Rinsate and DIFB Chloroform and Chloride Levels
It is expected that chloroform and chloride sources will be eliminated from the DIFBs
after the DI system is upgraded to support the high volume of DI water in the system
during the rinsate process. An appropriate DI system has been identified. Installation is
scheduled to follow construction of other capital improvements in the Mill in late 2012 or
early 2013. Data collected after the completion of the system upgrades will determine if
any further action is necessary to eliminate rinsate contamination.
Verifying That the Corrective Action Has Eliminated the Problem
Verification that chloroform and chloride contamination has been eliminated will occur
upon completion of the system upgrades and receipt of at least the two quarters of data. If
chloride contamination persists then additional sources will be researched and the
investigation will continue.
6.2 Assessment of Previous Quarter's Corrective Actions
The fourth quarter 2011 report identified corrective actions for sample/duplicate RPD
results. During the first quarter of 2012, all analytical results for the sample/duplicate
pairs were within the 20% acceptance limits. All results of the RPD test are provided in
Tab 1.
7.0 CONCLUSIONS AND RECOMMENDATIONS
The water level contour maps for the first quarter, 2012 indicate effective capture of
water containing high chloroform concentrations in the vicinity of pumping wells MW -4,
MW-26, TW4-19, and TW4-20. A well-defined capture zone is not evident at TW4-4.
The capture zone associated with TW 4-4 is likely obscured by the low water level at
adjacent well TW 4-14 and the two orders of magnitude decrease in permeability south of
TW 4-4. However, the decrease in chloroform concentrations at TW 4-6 (located
downgradient of TW 4-4) since the fourth quarter of 2009 is likely related to TW 4-4
pumpIng.
First quarter, 2012 chloroform concentrations at many of the wells with detected
chloroform were within 20% of the values reported during the previous quarter,
suggesting that variations are within the range typical for sampling and analytical error.
Changes in concentration greater than 20% occurred in wells MW-26, TW4-2, TW4-6,
TW4-10, TW4-11, TW4-19, TW4-20, TW4-22 and TW4-26; the concentration in well
TW4-24 decreased from 1.2 J-lg/L to non-detect.
Of the wells showing changes in concentration greater than 20%, MW-26, TW4-19, and
TW4-20 are pumping wells. TW4-2 and TW4-11 are located adjacent to pumping well
MW-4; TW4-6 is located adjacent to pumping well TW4-4; TW4-10 is located adjacent
to pumping well MW-26; and TW4-22 is located adjacent to pumping well TW4-20.

N :\Required Reports\Chloroform Quarterly Monitoring Report\20 12 Q 1 \20 12_ Q 1 Chloroform_Report _text. doc
Fluctuations in concentrations at pumping wells and wells adjacent to pumping wells
likely result in part from changes in pumping. Between the current and previous quarters,
the concentration in TW 4-26, which is the most downgradient temporary well, increased
from 5.2 f.!g/L to 7 f.!g/L (although still lower than the 13 f.!g/L measured prior to
commencement of pumping at TW4-4. This increase is likely the result of its location
near the downgradient edge of the plume where changes in upgradient pumping are
expected to affect concentrations.
The highest chloroform concentration (11,000 f.!g/L) was detected at pumping well TW4-
20. Since the last quarter, the chloroform concentration in TW4-20 increased from 7,900
f.!g/L to 11,000 f.!g/L, the concentration in adjacent pumping well TW4-19 decreased
from 2,200 f.!g/L to 650 f.!g/L, the concentration in nearby well TW 4-21 increased slightly
from 390 to 420 f.!g/L, and the concentration in nearby well TW4-22 decreased from 400
f.!g/L to 200 f.!g/L Fluctuations in concentrations in these wells are likely related to their
location near the suspected former office leach field source area in addition to variations
in pumping in TW4-20 and nearby wells. Regardless of these measured fluctuations in
chloroform concentrations, sampling of temporary wells TW 4-24 (located west of TW 4-
22) and TW4-25 (located north of TW4-21), indicates 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.
The chloroform concentration at well TW 4-6 increased from 21 f.!g/L to 38 f.!g/L. This
well has been outside the chloroform plume boundary since the fourth quarter of2010. In
the past, TW 4-6 has been both within and outside the plume. From the first quarter of
2009 through the fourth quarter of 2010, TW 4-6 was within the plume. Prior to that time,
between the time of installation in the second quarter of 2000 and the fourth quarter of
2008, TW 4-6 was outside the plume. Although fluctuations in concentrations have
occurred, this well likely remained outside the plume between installation in 2000 and the
fourth quarter of 2008 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) natural attenuation. The decreases in
concentrations at TW 4-6 since the fourth quarter of 2009 are likely the result of
up gradient pumping, in particular pumping at adjacent well TW4-4 (which commenced
in the first quarter of 2010). Chloroform remained non-detect at downgradient temporary
well TW4-23. TW4-23 and TW4-6 (with a chloroform concentration of 38 f.!g/L) bound
the chloroform plume to the south. TW4-8, TW4-12, TW4-13, TW4-14, and TW4-27
bound the chloroform plume to the east.
Continued pumping of MW-4, MW-26, TW4-19, and TW4-20 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. Continued pumping at TW 4-4 is also
recommended to improve capture of chloroform to the extent practical in the southern
portion of the plume where low permeability conditions exist. The general decrease in
chloroform concentrations at TW 4-6 from 1000 f.!g/L to 38 f.!g/L since the first quarter of
2010 is likely related to pumping at TW4-4. The decrease in the long-term rate of water
level rise at TW 4-6 since TW 4-4 pumping began, which suggests that TW 4-6 is within
22
N:\Required Reports\Chloroform Quarterly Monitoring Report\2012 Q 1 \2012_ Q 1 Chloroform _ Report_text. doc
the hydraulic influence of TW 4-4, is consistent with the decrease in chloroform
concentrations at TW 4-6. However, concentrations at TW 4-6 have been increasing
somewhat since reaching a low of 1 0 ~g/L in the second quarter of 20 11.

CLIENT: Denison Mines USA Corp
Project: 1 st Quarter Chloroform 2012 Report Date: 02/02/12
Sample Delivery Group: C12010623 CASE NARRATIVE
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 40C (±2OC)
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.
SOIL/SOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are NO (not detected), the sample meets EPA compliance criteria for
PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize its
branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.

Sample Delivery Group: C12010821 CASE NARRATIVE
LABORATORY COMMENTS
VOC (chloroform) analysis cancelled for MW-26 due to field issues.
ORIGINAL SAMPLE SUBMITTAL(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.
SOIL/SOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are NO (not detected), the sample meets EPA compliance criteria for
PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize its
branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.
