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 second quarter of 2011 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 (April through June), are discussed in the remainder of
this section.

Table 1 provides an overview of all wells sampled during the current period, 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.
2.1.2 Parameters Analyzed
Wells sampled during this reporting period were analyzed for the following constituents:
• Chloroform
• Chloromethane
• 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").
2.1.3 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.
All well levels used for groundwater contour mapping were measured and recorded
within 5 calendar days of each other as indicated by the measurement data in the
summary sheet under Tab D.

N:IRequired ReponslChlorororm Quanerly MoniloJing Reponl2() I I Q212011_Q2_Chlorororm_ReporUexl.doc
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 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, which is a separate Appendix A to the QAP. The Chloroform QAP
describes the differing needs of the chloroform investigation program, and is an
attachment to the GWDP QAP where QA requirements for the chloroform investigation
are addressed. 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.
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 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 established for the well by using a calibrated 5
3
N:lRequired ReporlslChloroform Quarterly MonitoIing Report120 II Q212011_Q2_Chlorotllrm_Rcport_lext.doc
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
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 mI.
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 mI.
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.

quarter that are not included in Tab D. 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. All of the water level measurements used for
the contour map were collected within 5 days of each other as indicated by the
measurement dates in the summary sheet under Tab D. A copy of the kriged
groundwater contour map generated from the first quarter 2011 data is provided under
TabE.
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 second 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.

N:IRcquired ReportslChloroform Quarterly Monitoring Reponl2011 Q21201 LQ2_Chloroform_Repon_tcxt.dac
3.0 QUALITY ASSURANCE AND DATA 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.
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.
Four 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. TW4-7R). The results of these analyses are included with the routine analyses under
TabH.
In addition, two DIFB, while not required by the Chloroform QAP, were collected and
analyzed for the same constituents as the well samples and rinsate blank samples.

N:IRcquired ReportslChloroform Quarterly Monitoring Reportl2011 Q212011_Q2_Chloroform_ReporUexl.doc
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 an amendment
to clarify this practice in the next revision of the QAP.
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 DIPB 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 1.
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
7
N:lRcquired ReporlslChlorofonn Quarterly Moniloring Repo\11201 1 Q212011_Q2_Chlorofonn_Reporuexl.doc
measurement dates in the summary sheet under Tab D. The results of this quarter's
review of field 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 TW4-2, TW4-3, TW4-6,
TW4-7, TW4-10, TW4-11, TW4-13, TW4-14, TW4-16, and TW4-26. 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. 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 least 2 consecutive
measurements. 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. 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.
Three wells did not meet the requirement for the stabilization of turbidity within 10%
RPD and two wells did not meet the requirement for the stabilization of redox potential
within 10% RPD. In all cases, the wells were purged to dryness prior to the achievement
of stabilization for turbidity and conductivity and as such the requirement to meet the
stabilization criteria does not apply.
Twenty-two turbidity measurements exceeded the QAP's 5 NTU goal. Of the twenty-
two wells, ten wells were 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.
DUSA's letter to DRC of March 26,2010 discusses further why turbidity does not appear
to be an appropriate parameter for assessing well stabilization. In response to DRC's
subsequent correspondence dated June 1, 2010 and June 24, 2010, DUSA has completed
a monitoring well redevelopment program. The redevelopment program reviewed the
available turbidity data for the nitrate wells and developed a list of wells that have
undergone redevelopment utilizing several strategies. The redevelopment strategies
include additional surging and bailing and overpumping as necessary. Surging and
bailing and overpumping for the nitrate, chloroform, and groundwater wells is complete.
Data from the redevelopment of the chloroform wells will be reviewed with the data from
8
N:IRcquired RcpOrlslChlorol'orm Quarterly Monitoring Reportl201 1 Q212011_Q2_Chlorofonn_Report_text.doc
the redevelopment of the nitrate and groundwater programs. A single report will be
prepared at the completion of the redevelopment program for the wells in all three
programs which is planned for submittal on or before the end of the third quarter 2011.
DUSA will review the redevelopment data and summarize the status of the Mill wells.
Redevelopment results will be discussed with DRC in an effort to come to a consensus
regarding turbidity considerations for the chloroform wells at the Mill site.
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 23 sets of sample results (22 wells, and 1 duplicates) had the reporting limit
raised for at least one analyte due to matrix interference and/or sample dilution. ill 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 VOC analytes.
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
results (described as activities in the QAP) are less than 5 times the required detection
limit. This standard is based on the EPA 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
9
N:IRequired RcponslChlorofmm Quarterly Monitoring Reponl2011 Q212011_Q2_Chloroform_RcporUe.t.doc
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%. The additional
duplicate information is provided for information purposes.
All analytical results for the sample/duplicate pairs were within the 20% RPD acceptance
limits. Results of the RPD test are provided in Tab 1.
3.4.8 Rinsate Sample Check
Rinsate blank sample checks are provided in Tab I.
Chloroform
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 was reported
as non detect. A comparison of the rinsate blank sample concentration levels to the QAP
requirements -that rinsate 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 met this criterion.
This criterion 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.
Chloroform has been present in the rinsate blanks in previous quarters. 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. It is known from EPA
studies that chloroform is frequently a byproduct of the chlorination process in potable
water supplies.
Based on the EPA documentation, DUSA believes the chloroform contamination in the
DI water is most likely the result of chlorination of the intake water used for the DI
system. Multiple sources cite the creation of chloroform as a byproduct of chlorination.
The following two sources have been attached as, EPA -Basic Information about
Disinfection Byproducts in Drinking Water: Total Trihalomethanes, Haloacetic Acids,
Bromate and Chlorite; and Water Research Net -Disinfection By-Products
Trihalomethanes, in Tab N to this report. The chloroform is most likely the result of the
chlorination of the potable water at the Mill which is subsequently fed to the DI system.
The water is free of chloroform prior to chlorination, as it is tested by the Utah
Department of Health, Division of Epidemiology and Laboratory Services on a routine
basis. The chlorine added reacts with the naturally occurring organic and inorganic
materials in the water.

N:IRequired RcpurtslChlolOLurm QuarteJiy Monitoring Reportl2011 Q212011_Q2_Chloroform_Rcport_text.doc
During the Q2 2011 event a second 55-gallon rinse with DI water was added to address
the nitrate contamination in the rinsate blank process resulting from the nitric acid rinse
in the decontamination procedure. The rinsate blank was collected from the second DI
rinsate water after the second 55-gallons of DI are pumped. The addition of this step
eliminated nitrate contamination, but "stressed" the DI system due to increase in volume
of water being used. The DI system is designed to remove the chloroform; however, due
to the large volume of DI water processed through the system during the chloroform
sampling events to accommodate the decontamination needs, breakthrough appears to
occur under heavy usage when the system is "stressed". Removal of chloroform and
other organics is accomplished by the "activated carbon" portion of the DI system. The
performance of this portion of the DI system is directly proportional to the volume of
water treated and, due to the large volumes of water treated in a short time, the system
becomes "stressed" and performance decreases resulting in chloroform "breakthrough".
Corrective actions for this issue are described in Section 6.1.
Nitrate
A review of the analytical results reported for rinsate blank samples indicated that none
of the rinsate blank samples contained nitrate. A DIFB was analyzed and was reported as
nondetect.
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 an MSIMSD (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 MSIMSD pair, and the QAP does not specify that the
MSIMSD pair be prepared on DUSA samples only. Acceptance limits for MSIMSDs 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 MSIMSD 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
11
N:IRcquired ReporlslChloro[onn QUalterly Monitoring Reporll2011 Q212011_Q2_Chlorofonn_ReporUext.doc
does not require this level of review, and the results of this review are provided for
information only.
The information from the Laboratory QAfQC 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 1. 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. Furthermore, the nitrate samples
with MS/MSD recoveries outside of the laboratory established limits are not Denison
samples and as such are not applicable to the Mill samples. 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 QAfQC 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 1. One
surrogate recovery was above the laboratory established acceptance limits or that had a
high recovery, indicating a high bias to the individual sample results. A high bias means
that reported results will be higher than the actual results. There is no effect on the
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 QAfQC 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 at the site ranges from
generally southwesterly in the western portion of the site to generally southerly in the
12
N:IRequircd RcponslChioroform Quarlerly MonilOring Reportl2011 Q21201 I_Q2_Chloruform_Report_lexl.doc
eastern portion of the site. 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 of 2010.
Although pumping at TW 4-4 has depressed the water table in the vicinity of TW 4-4, the
well has apparently not been pumped long enough to have affected water levels at
adjacent wells sufficiently for a well-defined cone of depression to be evident. Changes
in water levels at wells immediately south of TW4-4 resulting from TW4-4 pumping are
likely muted because TW4-4 is located at a transition from relatively high to relatively
low permeability conditions south (down gradient) of TW4-4. The permeability of the
perched zone at TW4-6 and TW4-26 is approximately 2 orders of magnitude lower than
at TW4-4. Any drawdown of water levels at wells immediately south of TW4-4 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 TW 4-4 and TW 4-6 increased by
nearly 2.7 and 2.9 feet, respectively, between the fourth quarter of 2007 and the fourth
quarter of 2009 (just 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 TW 4-6 has been
reduced since the start of pumping at TW4-4 (first quarter of 2010) to approximately 0.35
feet/year suggesting that TW 4-6 is within the hydraulic influence of TW 4-4.
The lack of a well-defined cone of depression at TW4-4 is also influenced by the
persistent, apparently anomalously low water level at non-pumping well TW4-14, located
east of TW4-4 and TW4-6. For the current quarter, the water level at TW4-14 is
approximately 13 feet lower than the water level at TW4-6 and approximately 19 feet
lower than TW 4-4 even though TW 4-4 is pumping. The low water level at TW 4-14 is
considered anomalous because it appears to be downgradient of all three wells TW 4-4,
TW4-6, and TW4-26, yet there is no chloroform at TW4-14. Chloroform has apparently
migrated from TW4-4 to TW4-6 and from TW4-6 to TW4-26 which suggests that TW4-
26 is actually downgradient of TW4-6, and TW4-6 is actually down gradient of TW4-4,
regardless of the flow direction implied by the low water level at TW4-14. The water
level at TW4-26 (5537.6 feet amsl) is, however, lower than water levels at adjacent wells
TW4-6 (5538.4 feet amsl), and TW4-23 (5541.9 feet amsl)
Current water level data indicates that regardless of whether the water level at TW4-14 is
considered anomalous, the likelihood that chloroform could move undetected toward the
eastern property boundary is minimal. The historical chloroform data indicates that the
direction of perched water flow is to the south-southwest from TW 4-4 towards TW 4-6
and TW4-26, and not to the southeast toward TW4-14.
For these reasons, DUSA believes that the existing monitoring well network adequately
bounds the chloroform plume and that additional wells are not necessary to the southeast
of TW 4-4 and TW 4-6. At the present time, the data from the existing wells in the area
seem adequate, especially considering the shrinkage of the chloroform plume that has
occurred since TW 4-4 pumping began.

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 first quarter of 2011, as submitted
with the Chloroform Monitoring Report for the first quarter of 2011, are attached under
TabE.
A comparison of the water table contour maps for the second quarter of 2011 to the water
table contour maps for the previous quarter (first quarter of 2011) indicates similar
patterns of drawdown related to pumping ofMW-4, MW-26, TW4-4, 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. As discussed in Section 4.1.1, pumping
at TW4-4, which began in the first quarter of 2010, has depressed the water table near
TW4-4, but does not yet appear to have affected water levels at adjacent wells
sufficiently for a well-defined cone of depression to be evident.
Reported increases in water levels of approximately 5 feet occurred in MW -18, of
approximately 7 feet occurred in both MW-35 and TW4-3, and of approximately 5 feet
occurred in TW4-21. The apparent increase in water level at MW-35 this quarter was due
to use of a surveyed rather than estimated casing elevation. A reported decrease in water
level of approximately 5 feet occurred in well MW-20. The low water levels in MW-20
are potentially the result of the recent surging and bailing activities. Reported increases
in water levels of nearly 11 feet occurred in pumping well MW -4, of approximately 20
feet occurred in pumping well TW4-19, and of approximately 16 feet occurred in
pumping well TW 4-20. A reported decrease in water level of approximately 9 feet
occurred in pumping well MW -26. The water level change at the remaining pumping
well (TW 4-4) was less than 1 foot.
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 draw down) of approximately 9
feet occurred in well MW-26 and the largest increase (decrease in drawdown), of
approximately 20 feet, occurred at TW4-19. The water level reported for MW-18 during
the current quarter is more similar to historical measurements than that reported for the
previous quarter.

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 upgradient 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 TW4-4. As with the other
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, TW4-
19, and TW4-20 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 these pumping wells is
occurring. Overall, the combined capture of MW-4, MW-26, TW4-19, and TW4-20 has
not changed significantly since the last quarter. As noted in Section 4.1.2, a decrease in
water level (increase in drawdown) of approximately 9 feet occurred at MW -26, and
increases in water levels (decreases in draw down) of nearly 11 feet occurred at MW-4, of
approximately 20 feet occurred in TW4-19, and of approximately 16 feet occurred in
TW4-20. The increase in draw down at MW-26 has slightly increased the apparent
capture zone of this well relative to other nearby pumping wells. As discussed in Section
4.1.1, TW4-4 has apparently not been pumped long enough for a well-defined capture
zone to become evident, and the drawdown associated with TW4-4 is likely less
apparent due to the low water level at TW4-14. The capture zone associated with TW4-
20 this quarter is not distinguishable from the larger capture zones of MW-26 and TW4-
19.
Chloroform concentrations exceeding 70 !-\-glL have occurred at some locations
downgradient of pumping wells (for example, at TW4-6, located immediately south of
TW4-4), 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 down gradient 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
15
N:lRequilcd ReporlslChlorofOlm QuarteJly Monitoring Reportl2011 Q212011_Q2_Chlororoml_Report_tcxt.doc
TW 4-4 is demonstrated by the decrease in chloroform concentrations at TW 4-6 from
1000 IlglL to 9.6 IlgIL, and at TW4-26 from 13 IlglL to 2.9 IlglL since pumping began at
TW4-4. Concentrations at these wells have decreased substantially even though they do
not unambiguously appear to be within the hydraulic capture of TW4-4. 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 TW4-4 does suggest that TW4-6 is within the hydraulic
influence of TW4-4. Regardless of whether TW4-6 can be demonstrated to be within
hydraulic capture of TW4-4, Pumping TW4-4 acts to cut off the source of chloroform to
TW 4-6 and TW 4-26 by the mechanisms discussed above.
4.2 Review of Analytical Results

Included under Tab J of this Report is a current chloroform isoconcentration map for the
Mill site.
4.2.2 Chloroform Concentration Trend Data and Graphs
Attached under Tab K is a table 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, TW4-21, and TW4-26;
b) Chloroform concentrations have decreased by more than 20% in the following
wells compared to last quarter: TW4-6, TW4-1O, TW4-18, TW4-20, TW4-22,
and TW4-24;
c) Chloroform concentrations have remained within 20% in the following wells
compared to last quarter: MW-4, TW4-1, TW4-2, TW4-4, TW4-5, TW4-7,
TW4-11, TW4-16, and TW4-19; and
d) MW-32, TW4-3, TW4-8, TW4-9, TW4-12, TW4-13, TW4-14, TW4-23, and
TW4-25 remained 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.
16
N:IReqllired ReportslChlOlOloITl1 QUalterly Monitoring Repor112011 Q212011_Q2_Chloroform_Reporuext.doc
Wells MW-26, TW4-6, TW4-1O, TW4-18, TW4-20, TW4-21, TW4-22, TW4-24, and
TW4-26 had changes in concentration greater than 20%. Of the latter, MW-26 and TW4-
20 are pumping wells. TW4-6 is located adjacent to pumping well TW4-4; TW4-1O is
located adjacent to pumping well MW-26; TW4-18 and TW4-21 are located adjacent to
pumping well TW4-19; and TW4-22 is located adjacent to pumping well TW4-20.
Fluctuations in concentrations at pumping wells and wells adjacent to pumping wells
likely result in part from changes in pumping. The decrease in concentration at TW4-24
from 1.8 to 1.1 !!glL and the increase in concentration at TW4-26 from 2 to 2.9 !!glL are
likely the result of analytical error because the concentrations are close to the detection
limit. The decrease in concentration at TW4-6 is likely related to pumping at TW4-4.
Pumping well TW4-20 had the highest detected chloroform concentration. Since the last
quarter, the chloroform concentration in TW4-20 decreased from 31,000 !!glL to 8,100
!!glL, the concentration in adjacent pumping well TW4-19 increased from 3,400 !!glL to
4,000 !!glL, the concentration in nearby well TW4-21 increased from 230 to 290 !!glL,
and the concentration in nearby well TW4-22 decreased from 1,300 I-tglL to 210 I-tglL.
Wells TW4-23 and TW4-25 remained non-detect for chloroform. TW4-24, located west
of TW4-22, and TW4-25, located north of TW4-21, bound the chloroform plume to the
west and north.
The chloroform concentration in TW4-6 decreased substantially from 47 !!glL to 9.6
!!glL, keeping the well outside the chloroform plume boundary. Concentrations at TW4-6
have been on a downward trend since initiation of pumping of TW 4-4 in the first quarter
of 2010, and have decreased from 1000 !!glL to 9.6 !!glL since that time. TW4-6,
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 up gradient chloroform removal by pumping, and 2) natural attenuation.
Because TW4-6 is again outside the plume boundary, TW4-6 and TW4-23 bound the
chloroform plume to the south.
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 I-tglL within only 2 quarters whereas 16 quarters were required for
concentrations in TW4-6 to increase from non-detect to only 81 !!glL. 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
recently installed well TW4-26 are also expected to be relatively low due to up gradient
pumping and low permeability conditions.
The chloroform concentration in TW4-16, located immediately downgradient of the
chloroform plume, increased slightly from 15 I-tglL to 16 I-tg/L. Slight expansion and
17
N:IRequired RcpOrlslChloroform Quarterly Monitoring Report12011 Q212011_Q2_Chloloform_Rcport_text.doc
contraction of the chloroform plume boundaries in response to changes in upgradient
pumping are expected to impact the concentrations at TW4-16. In addition, the
southernmost boundary of the plume is again between TW 4-4 and TW 4-6 (located just
north of southernmost temporary well TW4-26). The decrease in concentration at TW4-6
(from 47 /.tg/L to 9.6 /.tg/L) is likely due to upgradient pumping, in particular pumping at
TW4-4.
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
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 TW4-4, 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 June 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 cunently-
active pumping wells.
During the review of the weekly depth to water and flow measurements the Field
Coordinator noted that there were inconsistencies in how the flow measurements were
made. The flow measurements were adjusted by the Field Coordinator and retraining of
the Field Staff was completed to assure conect and consistent recording of
measurements.
5.4.1 MW-4
Approximately 85,849 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
4.1 gpm throughout the quarter. The well is not pumping 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 1 evaporation pond through a
pipeline installed specifically for that purpose.
5.4.2 TW 4-19
Approximately 159,239 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 8.1 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.
It was noted by Field Personnel on June 1, 2011 that the pump in TW4-19 was not
working. The pump was replaced on June 2, 2011. Field Personnel collected
measurements the following week as scheduled.
Additionally, during the June 27, 2011 depth to water and flow measurements it was
noted by Field Personnel that no flow measurement was taken, due to a power outage
19
N:lRcqu~ed ReporlslChloroform Quarterly Moniloring Rcportl2011 Q212011_Q2_Chlocoform_Rcport_lexl.doc
upon their arrival on June 27, 2011. Investigation into the power outage noted that the
power had been out since June 24, 2011; however, the environmental staff were not
aware of the outage until June 27, 2011. Field Personnel returned the following week
and collected the measurements indicating power had been restored. In both instances
noted above, DUSA provided a verbal notification to UDEQ, but written notifications
were not necessary due to the issues being addressed with 24 hours of discovery by
DUSA Management.
5.4.3 MW-26
Approximately 55,801 gallons of water were pumped from MW-26 during the quarter.
The average flow rate from MW-26, when the pump was pumping, was approximately
5.8 gpm throughout the quarter. The well is not pumping 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 1 evaporation pond through a
pipeline installed specifically for that purpose. During the April 18, 2011 weekly depth
to water and flow measurements it was noted by Field Personnel that a new meter was
installed on April 16, 2011. Field Personnel were able to collect measurements as
scheduled indicating the pump replacement was successful.
5.4.4 TW 4-20
Approximately 67,908 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
9.8 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 1 evaporation pond through a pipeline installed
specific all y for that purpose.
5.4.5 TW4-4
Approximately 80,335 gallons were pumped from TW4-4 during the quarter. The
average flow rate, when the pump was pumping, was 8.2 gpm. The well is not pumping
continuously, but is set on a water elevation device. When the water reaches a set point,
the pump turns on until the water level drops to another set point. The water is directly
transferred to the Cell 1 evaporation pond through a pipeline installed specifically for that
purpose.
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 below, indicating
that a total of 567.4 pounds of chloroform have been removed to date.
5.6 Inspections
Denison has submitted an Operations and Maintenance Plan, Chloroform Pumping
20
N:IRequired ReporlslChloroform Quarterly Monitoring Reportl2011 Q212011_Q2_Chlorofofm_Reporuexl.doc
System, White Mesa Mill, Blanding, Utah, Revision 2.1 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 an
inspection form. An example of the form as well as completed reports for the quarter
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,
Chloroform Pumping System, White Mesa Mill, Blanding, Utah, Revision 2.1 had not
been received.
Operational problems in the pumping wells are summarized above.
5.7 Conditions That May Affect Water Levels in Piezometers
Water was added to the upper and lower wildlife diversion ponds during the quarter. The
middle wildlife pond had no water added and is dry at this time.
6.0 CORRECTIVE ACTION REPORT
Necessary corrective actions identified during the current monitoring period are described
below.
6.1 Rinsate Blank Sample Chloroform Levels
Identification and Definition of the Problem
Rinsate Chloroform Levels
Chloroform has been present in the rinsate blanks in previous quarters and was addressed
through a change in the decontamination procedures and rinsate blank frequency
suggested by UDEQ personnel. However, nitrate contamination in rinsate blanks has
continued to be problematic in both the nitrate and chloroform sampling program. To
address the nitrate contamination in the nitrate and chloroform sampling programs, an
additional rinse with 55-gallons of DI water has been added to the decontamination
process. The added 55-gallons of DI water per decontamination of the portable pump has
caused chloroform to reappear in the rinsate blanks. DUSA believes that the potential
source for the chloroform present in the rinsate blanks appears to be related to the
increasing volume of DI water used in the rinsate process due to the second 55-gallon
rinse with DI water. The chloroform present in the rinsate blanks is most likely present in
the DI water and is not the result of inadequate decontamination of the purging pump.
The chloroform contamination in the DI water is most likely the result of chlorination of
the intake water used for the DI system.
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
21
N:lRequircd ReporlslChlurolorm Quarterly Moniloring Rcportl201 L Q212011_Q2_ChlOl()form_Reporucx~doc
Rinsate Blank Sample Chloroform Levels
As discussed above, chloroform is most likely entering the rinsate blanks from the
chlorination process. The Dr system is showing signs of breakthrough at times of high
usage. To address the issue, the QA manager plans to evaluate and implement upgrades
to the Dr system to ensure its ability to support the high volume of Dr water needed for
the rinsate process.
Determination of a Corrective Action to Eliminate the Problem
Rinsate Blank Sample Chloroform Levels
The chloroform contamination in the Dr water is most likely the result of chlorination of
the intake water used for the Dr system. Based on low level detections this quarter, the
additional of a second Dr 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 Dr water being pumped through the system.
Assigning and Accepting Responsibility for Implementing the Corrective Action
Rinsate Blank Sample Chloroform 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 Blank Sample Chloroform Levels
Chloroform sources will be removed after the Dr system is upgraded to support the high
volume of Dr water in the system during the rinsate process. The QA manager is
developing a plan for the system update. 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 contamination has been eliminated will occur upon
completion of the system upgrades and receipt of at least the two quarters of data. If
chloroform contamination persists then additional sources will be researched and the
investigation will continue.
6.2 Assessment of Previous Quarter's Corrective Actions
The first quarter 2011 report identified corrective actions for nitrate contamination in the
rinsate blank samples. Nitrate contamination was eliminated in the second quarter 2011
with the addition of a second Dr water rinse in the decontamination process. The rinsate
blank was collected from the second Dr rinsate water after the second 55-gallons of Dr
were pumped.

7.0 CONCLUSIONS AND RECOMMENDATIONS
The water level contour maps for the second quarter, 2011 indicate that effective capture
of water containing high chloroform concentrations is occurring in the vicinity of
pumping wells MW-4, MW-26, TW4-19, and TW4-20. TW4-4 has apparently not been
pumped long enough for a well-defined capture zone to become evident. Furthermore, the
capture zone associated with TW 4-4 may be less apparent because of the low water level
at adjacent well TW4-14. However, the decrease in chloroform concentrations at TW4-6,
located downgradient of TW4-4, is likely related to TW4-4 pumping.
First quarter, 2011 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, TW4-6, TW4-1O,
TW4-18, TW4-20, TW4-21, TW4-22, TW4-24, and TW4-26; the concentration in well
TW4-24 decreased slightly from 1.8 f,tglL to 1.1 f,tglL and the concentration in well TW4-
26 increased slightly from 2 f,tglL to 2.9 f,tglL.
Of the wells showing changes in concentration greater than 20%, MW-26 and TW4-20
are pumping wells. TW4-6 is located adjacent to pumping well TW4-4; TW4-1O is
located adjacent to pumping well MW-26; TW4-18 and TW4-21 are located adjacent to
pumping well TW4-19; and TW4-22 is located adjacent to pumping well TW4-20.
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 TW4-26, which is the most downgradient temporary well, increased
slightly from 2 f,tglL to 2.9 f,tglL.
The highest chloroform concentration (8,100 f,tglL) was detected at pumping well TW4-
20. Between the current and previous quarters, the chloroform concentration in TW4-20
decreased from 31,000 f,tglL to 8,100 f,tglL, the concentration in adjacent pumping well
TW4-19 increased from 3,400 f,tg/L to 4,000 f,tglL, the concentration in nearby well
TW4-21 increased from 230 to 290 f,tglL, and the concentration in nearby well TW4-22
decreased from 1,300 f,tglL to 210 f,tg/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 TW 4-20 and nearby wells. Regardless of these
measured fluctuations in chloroform concentrations, sampling of temporary wells TW 4-
24 (located west of TW4-22) 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 TW4-25, and was detected at a concentration of
1.1 f,tg/L at TW4-24.
The chloroform concentration at well TW4-6 decreased substantially from 47 f,tglL to 9.6
f,tglL. This well has been outside the chloroform plume boundary since the fourth quarter
of 2010. In the past, TW4-6 has been both within and outside the plume. From the first
quarter of 2009 through the fourth quarter of 2010, TW4-6 was within the plume. Prior to
23
N:IRequircd RCPOllsIChlOioform Quarlerly Moniloring Reportl2011 Q212011_Q2_Chlorofo,m_Report_leXl.doc
that time, between the time of installation in the second quarter of 2000 and the fourth
quarter of 2008, TW4-6 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 TW4-6 since the fourth quarter of 2009 are likely the result of
upgradient pumping, in particular pumping at TW 4-4. Chloroform remained non-detect at
downgradient temporary well TW4-23. TW4-23 and TW4-6 (with a chloroform
concentration of 9.6 IAglL) bound the chloroform plume to the south.
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 TW4-6 from 1000 IAglL to 9.6 IAglL 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
the hydraulic influence of TW 4-4, is consistent with the decrease in chloroform
concentrations at TW 4-6.
DUSA believes that the eXlstmg monitoring well network adequately bounds the
chloroform plume and that additional wells are not necessary to the southeast of TW 4-4
and TW4-6. At the present time, the data from the existing wells in the area seem
adequate, especially considering the shrinkage of the chloroform plume that has occurred
since TW 4-4 pumping began.

Comments: all depths were checked on 6/21/11 with the exeption of the DR series wells, they were
checked on 6/22/11. we don't have logged depths on the DR series as of yet. We obtained the MW-36
and MW-37 logged depths as a special request. We still do not have a tagged depth on the MW series
of wells as they all have dedicated pumps in the wells and we do not want to distrub the column.

Sample Delivery Group: C 11050927 CASE NARRATIVE
ORIGINAL SAMPLE SUBMITIAL(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 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. If so, ENERGY LABORATORIES will utilize its
branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the

Sample Delivery Group: C11060152 CASE NARRATIVE
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 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. 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.

CLIENT: Denison Mines USA Corp
Project: 2nd Quarter Chloroform 2011 Report Date: 06/22/11
Sample Delivery Group: C11060430 CASE NARRATIVE
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample subm ittals 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 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. 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: C 11061150 CASE NARRATIVE
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 ch illing 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.

What aN EPA's drfnking Woller regu"Uons for dlorinlacUon bypnHlucts7
In 1974, Congress passed the Safe Dlinking Water Act This law reqLlices EPA to determine the level of contaminants In <kinking water at which no adV8fllll helilh effecb are
likely to occur. These non-enforceable health goals. lIMed solely on possible health risks and exposure over II lirelime, with an adeqtJata margin 01 safely. are called I118ldmum
c:ontaminantlevel goals (MClG). Contaminants are any physical, chemical, biological at radiological subslalces 01' matter in water. EPA sals MClGs based on !he best
avaUable science to prevent polenHal health problems.
Based on the MClG, EPA sats an enforceable regulation caIlad a maximum contaminant level (MCl). MCls are set as c\ose to tha health goals as possible. considering cost,
benefits alii! the abnrly of public water systems to detect and I1!move contaminants using suitable Ireatment ledmologles. MCls for disinfection byproductJ ara set at the
rollowing levels:

The following drinking water regulaUons apply to disinfectants and disinfection byproducts:
Sh1gO ! pl.!nrwtants lJIIeI Plsjnroetlon ByprodUlils Ryte (S1age t pspl (December 18,1998)
The Stage 1 Disinfectants and Disinfection Byproducls Rule reduces exposure to disinrection byproducls for customers of community water systems end non-Iransienl
non-community systems, including Ihose serving rewer than 10,000 people, Chat add a dlsinrectant 10 the drlnkilg water during ..,y part of the Irealment process.
Stage 2 QjSjnfeclilllS and [)jsjnfec!ign Bvorgdycls Ryle /Slade 2 PBf» (December 15, ZOO5)
Stage 2 DBP rull, builds upon earlier rules that addressed disinfeclion byproduct. to improve your drinking water quality and provide addmonal public hea~h prolaction
from disinfection byproducts.
The Sare Drinking Waler Act requires EPA to periodically review the naUonaJ primary drinking water regulation for each contamilTillt and revise the regulation, if appropriate.
based on new scientillc data. EPA will include the Disinfectants and Disinfection Byproducts JU~ in a I\.oture review cycle.
• More fnfoana!lgo 90 lhe SIx 'fear Bin/lew of prinkfnq Water Slaadards
How willi know if disInfection bypro duets are in my drinking waler1
\lVhen rouUne monitoring indicates that disinfection byproduct levels are abovOlthe MCl, your water supplier must take steps 10 reduce the amount of disinfection byproduclsso
lhallhey are befow that level. Weter suppliers mU5t notify their customers as 0000 as pradical, but no Ialer than 30 days aller the system learns of the violation. Additional
actions, such as provIding alternative drinking water suppKes. may be required to prevent serious risks to public health.
• See EPA',. plJbllc noUfication reQylrements tIlr public wafer systems_
How will disinfection byproducts be removed from my drinking water?
Waler systems !hat use surface water or ground watar under the direct influence of surfaca water and use conventional filtration treatment are required to remove specified
percentages of organic materials that may react with disinfectants to fonn dislnrection byproducts, prior ID disinfection. Other conlrol strategies include modiflcation of disinrection
practices in a manner Ihat stiU provides adequate protection against pathogens.
How do t learn mont about my drinking wal8r1
EPA strongly encourages pllOpla to leam more about their drinking water, and to support local efforts to protect the supply of sare drinking water and upgrade the community
water system. Your wafer bil or telephone book's govemment Ustings are a gOOd starting poinl lor local information.
ConJac/ your water utility. EPA requires all community water systems 10 prapare and deliver an annual consumer confidence report (eCR) (sometimes called a water quality
report) tIlr their cuslomers by July 1 of each year. If your water provider is not a community waler system. or if you have a private waler supply, reque.t a copy from a ne.by
community waler system.

Disinfection By-Products
Trihalomethanes
Trihalomethanes (THM) are a group of four chemicals that are formed along with other disinfection by
products when chlorine or other disinfectants used to control microbial contaminants in drinking water
react with naturally occurring organic and inorganic matter in water. The trihalomethanes are
chloroform, bromodichloromethane, dibromochloromethane, and bromoform. EPA has published the
Stage 1 Disinfectants and Disinfection Bvproducts Rule to regulate total trihalomethanes (TTHM) at a
maximum allowable annual average level of 80 parts per billion.
The four trihalometbanes (THM's) listed below:
Trichloromethane I CRCl3 I (chloroform)
I I>ibromochloromethane IICHClBr21
I Bromodichloromethane IICHCl2Bri
Tribromomethane I CHBr3 I (bromoform)
are all by-products of chlorination. They are Cancer Group B carcinogens (shown to cause cancer in
laboratory animals). Trichloromethane (chloroform) is by far the most common in most water systems.
Dibromochloromethane is the most serious cancer risk, (0.6 ug/l to cause a 10-6 cancer risk increase)
followed in order by Bromoform (4 ug/l), and Chloroform (6 ug/l). Current regulations limit the
concentration of these 4 chemicals added together (total trihalomethane or TITIM levels) to 100 ug/l.
Treatment
THM levels tend to increase with pH, temperature, time, and the level of "precursors" present.
Precursors are organic material which reacts with chlorine to form THM's. One way to decrease THM's
is to eliminate or reduce chlorination before the filters and to reduce precursors.. There are more

precursors present before filtration, so we want to reduce or eliminate the time chlorine is in contact with
this water. If some oxidation before filtration is required, an alternative disinfectant like potassium
permanganate or peroxide could be considered. Note that this may not be an option ifprechlorination is
necessary to achieve required CT values.
The EPA has indicated that the best available technology for THM control at treatment plants is removal
of precursors through "enhanced coagulation". Enhanced coagulation refers to the process of optimizing
the filtration process to maximize removal of precursors. Removal is improved by decreasing pH (to
levels as low as 4 or 5), increasing the feed rate of coagulants, and possibly using ferric coagulants
instead of alum.
For point of use systems at homes, activated carbon filters are the most effective treatment. Reverse
osmosis units will also eliminate trihalomethanes.
Upcoming Regulations
The EPA is considering extensive revisions to the regulations covering disinfection by-products
(DBP's). The limit for TTHM's would be lowered to 80 ugll, and three additional categories ofDBP's .
This standard will replace the current standard of a maximum allowable annual average level of 100
parts per billion in December 2001 for large surface water public water systems. The standard will
become effective for the first time in December 2003 for small surface water and all ground water
systems
Haloa~etic acids (monobromoacetic acid, dibromoacetic acid, monochloroacetic acid, dichloroacetic
acid, and trichloroacetic acid) are byproducts of chlorination similar to THM's. An MCL for total
haloacetic acids of 60 ug/l is expected. Excessive levels can cause nervous system and liver effects.
Chlorite is to be regulated with an MCL set at 1 mg/I. Excessive levels can cause hemolytic anemia.
Bromate, the other newly regulated DBP , is a concern only for systems using ozone. An MCL of 10
ug/l is expected. Excessive levels causes gastrointestinal, kidney, and hearing effects.
