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 of UAC 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 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 (January through March), 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 \Required Rcports\Chlorofbrm Quarterly Monitonng Report\2011 Q1V2011_Q l_Chloroform_Report_text 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 YRequired Reports\Chloroform Quarterly Monitoring Report\2011 Ql\201 l_Ql_Chtoroform_Report_tcxt 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 ml.
bottle which is provided by the Analytical Laboratory. The nitrate/nitrite sample
is also not filtered and is preserved with H2SO4;
• 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.

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 4th quarter 2010 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 first quarter chloroform contaminant
investigation are provided under Tab H of this Report. Also included under Tab H are
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 \Required Reports\Chlorofonn Quarterly Monitonng Report\2011 Ql\201 l_Ql_Chlorofonn_Report_tort doc
3.0 QUALITY ASSURANCE AND DATA VALIDATION
The QA Manager performed a QA/Quality 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 QA/QC are discussed in
Sections 3.4.4 through 3.4.9 below.
The analytical laboratory has provided summary reports of the analytical quality QA/QC
measurements necessary to maintain conformance with National Environmental
Laboratory Accreditation Conference ("NELAC") certification and reporting protocol.
The Analytical Laboratory QA/QC 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
QA/QC 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.
Two trip blanks were provided by Energy Laboratories and returned with the quarterly
chloroform monitoring samples.
Six 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.
It is important to note that the rinsate blank sample frequency was modified in the fourth
quarter 2010 as recommended by UDEQ personnel present on site for split sampling.
Previously, a rinsate blank sample was collected after each decontamination of the
nondedicated pump and prior to the next use of the pump. Per an e-mail from Mr. Phil
Goble, dated October 4, 2010, rinsate blank samples are only required at the beginning of
6
N VRequired Reports\Chloroform Quarterly Monitonng Report\2011 Ql\2011 _Q 1 Chloroform Report text doc
the sampling event and at the beginning of each day of sampling. The frequency change
was implemented immediately and the rinsate blank frequency has been modified for all
sampling events since.
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 Samplmg SOPs
On a review of adherence by Mill personnel to the existing sampling SOPs, the QA
Manager observed that QA/QC 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 QA/QC evaluation, a holding
time check, a receipt temperature check, an analytical method check, a reporting limit
evaluation, a trip blank check, a QA/QC 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 QA/QC 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
7
N \Required Reports\Chlorofbrm Quarterly Monitonng Report\2011 QIV201 l_Ql_Chlorororm_Report_text doc
mformation: 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 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 TW4-1, TW4-2, TW4-3,
TW4-7, TW4-10, TW4-13, TW4-14, TW4-16, TW4-22, 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. In
addition, TW4-6, and TW4-11, were pumped to dryness after 2 casing volumes were
evacuated.
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.
Six 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 conductivity 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-three turbidity measurements exceeded the QAP's 5 NTU goal. Of the twenty-
three wells, nine 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
8
N \Reqmred Reports\Chlorofonn Quarterly Monitonng Report\2011 Ql\2011 _Q 1 _Chloroform_Report_text doc
subsequent correspondence dated June 1, 2010 and June 24, 2010, DUSA is currently
implementing a monitoring well redevelopment program. The redevelopment program
has reviewed the available turbidity data for the nitrate wells and has 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 and chloroform wells is complete.
Redevelopment of the groundwater wells is in progress. Data from the redevelopment of
the chloroform wells will be reviewed with the data from 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 25 sets of sample results (23 wells, and 2 duplicates) 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 VOC analytes.

N VRequnrd Reports\Chloroform Quarterly Monitonng Report\2011 Q1N201 l_Ql_Chloroform_Report_textdoc
3.4.7 QA/QC 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
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 except for chloroform in sample/duplicate pairs TW4-19/TW4-65
and TW4-10/TW4-70 were within the 20% RPD acceptance limits. The chloroform
results for both sets of duplicate pairs are greater than 5 times the reporting limit and both
sets of duplicate pairs results were diluted 100-fold or more due to the high chloroform
concentration. The RPD greater than 20% is most likely due to a dilution error in the
laboratory. In addition, the results are significantly above the groundwater quality
standard of 70 ug/L and as such the noncompliant RPD results do not affect the quality or
usability of the data. 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.

A review of the analytical results reported for rinsate blank samples indicated that none
of the rinsate blank samples contained chloroform. A DIFB was analyzed and was
reported as nondetect.
Nitrate
Five rinsate blank samples had reported low level concentrations of nitrate. A DLFB was
analyzed and was reported as nondetect for nitrate. 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 all but one of
the rinsate blank samples met this criterion. Rinsate blank TW4-9R had a reported
detection of nitrate of 0.2 mg/L while the previously sampled well was reported as
nondetect.
This criterion however, is irrelevant and inappropriate for the rinsate blank sample data
collected during the nitrate 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
10
N \Required ReportsVChloroform Quarterly Monitonng Report\2011 Q1V201 l_Ql_Chlorofonn_Report_text doc
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.
Rinsate blank samples collected from the portable pump may be indicative of possible
cross-contamination resulting from pump usage during the purging process. Under the
Mill's sampling program the rinsate blank sample results are not directly applicable to the
sample results due to the use of different equipment (disposable bailers) for the sample
collection. The pump used for purging does not come into contact with the samples at
any time during the sample collection process and therefore comparison of the pump
rinsate blanks to the sample results is irrelevant and inappropriate. Any nitrate left in the
well from pump cross-contamination is reduced or negated by the influx of formation
water into the well in the time after purging and prior to sampling. Because samples are
collected the day following purging and using different equipment, the rinsate blank
concentration resulting from the pump use or decontamination fluids is not applicable to
the sample results because the pump does not contact the samples. As noted in previous
reports, an investigation into the source of the nitrate contamination present in the rinsate
blank samples has been ongoing. Below are the results of the source investigations, and
corrective actions are detailed in Section 6.2.
The nitrate levels reported in the rinsate blank samples for this investigation are similar to
the nitrate rinsate sample concentrations reported for the previous nitrate sampling
programs. Data collected for this ongoing investigation are as follows:
• The nitrate concentrations in the rinsate samples from both the chloroform
sampling program and the nitrate sampling program are just slightly above the
detection limit and are not dependent on or affected by the previous sample
concentrations.
• The presence of nitrate in both the chloroform and nitrate sampling programs
indicates that the contamination is due to external factors such as the nitric acid
rinse during the decontamination process and potential absorption of nitrogen
from the nitric acid into the non-stainless steel portions of the purging equipment
including the pump tubing and connectors.
The investigation into the nitrate in the rinsate blanks is continuing, with additional focus
on the rinsate collection process. Nitric acid introduced during the decontamination
process is the single highest possible source of nitrate ions. However, there may be some
contribution of nitrate from the decontamination process and/or the purging equipment.
To address these issues, the decontamination process and rinsate collection process are
being reviewed to determine if the purging equipment in combination with the nitric acid
wash used during the decontamination process are causing the nitrate detections in the
rinsate blanks.
Corrective actions are described in Section 6.2.

3.4.9 Other Laboratory QA/QC
Section 9.2 of the QAP requires that the laboratory's QA/QC 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 QA/QC results met these specified acceptance limits except as noted below.
The QAP Section 8.1.2 requires that an 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 QA/QC 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 above the laboratory established acceptance limits, do
not affect the quality or usability of the data because the recoveries above 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 QA/QC 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. The surrogate
recoveries that were outside of acceptance limits were above the upper limit 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
12
N \Required Reports\Chlorofbrm Quarterly Monitonng Report\2011 Ql\201 l_Ql_Cnlorofomi_Report_text doc
and all other surrogates were within limits. Furthermore, there are no QAP requirements
for surrogate recoveries.
The information from the Laboratory QA/QC 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 four chloroform pumping wells are
located, in each case with hand-drawn stream tubes, depicting hydraulic capture from the
pumping
The contour maps are based on the February 28, 2011 data for all wells.
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
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 TW4-4 has depressed the water table in the immediate vicinity of
TW4-4, the well has apparently not been pumped long enough to have measurably
affected water levels at adjacent wells. Therefore, a well-defined cone of depression is
not yet evident. Water levels at wells immediately south of TW4-4 have likely not
responded measurably to TW4-4 pumping because TW4-4 is located at a transition from
relatively high to relatively low permeability conditions south (downgradient) 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.
The lack of definition of a 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 TW4-4 even though TW4-4 is pumping. The low water level at TW4-14 is
considered anomalous because it appears to be downgradient of all three wells TW4-4,
13
N \Required Reports\Chloroform Quarterly Monitonng Report\2011 Ql\201 l_Ql_ChIoroform_Report_text doc
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 downgradient of TW4-4,
regardless of the flow direction implied by the low water level at TW4-14.
4.1.2 Comparison of Current Groundwater Contour Maps to Groundwater
Contour Map for Previous Quarter
The groundwater contour maps for the Mill site for the fourth quarter of 2010, as
submitted with the Chloroform Monitoring Report for the fourth quarter of 2010, are
attached under Tab E.
A comparison of the water table contour maps for the first quarter of 2011 to the water
table contour maps for the previous quarter (fourth quarter of 2010) indicates similar
patterns of drawdown related to pumping of MW-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 measurably affected water levels at adjacent
wells.
A reported increase in water level of approximately 3 feet occurred in Piez-3. Reported
decreases in water levels of approximately 5 feet occurred in well MW-18, of
approximately 21 feet occurred in well TW4-18, and of approximately 20 feet occurred in
well TWN-18. A reported increase in water level of approximately 11 feet occurred in
pumping well TW4-4, and a reported decrease in water level of approximately 18 feet
occurred in pumping well TW4-19. Water level changes at other pumping wells 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
18 feet occurred in well TW4-19 and the largest increase (decrease in drawdown), of
approximately 11 feet, occurred at TW4-4. Water levels reported for TW4-18 and TWN-
18 during the current quarter are more similar to historical measurements than those
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 TW4-4 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. TW4-4 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 other
pumping wells, pumping TW4-4 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 18 feet occurred at TW4-19, and an
increase in water level (decrease in drawdown) of approximately 11 feet occurred at
TW4-4. The increase in drawdown at TW4-19 has increased the apparent capture zone of
this well relative to other nearby pumping wells. As discussed in Section 4.4.1, TW4-4
has apparently not been pumped long enough for a well-defined capture zone to develop
and the drawdown associated with TW4-4 is likely less apparent due to the low water
level at TW4-14.
Chloroform concentrations exceeding 70 Lig/L have occurred at some locations
downgradient of pumping wells (for example, at TW4-6, located immediately south and
as discussed in Section 4.1.1, presumably downgradient 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 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 TW4-4 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 TW4-4 is demonstrated
by the decrease in chloroform concentrations at TW4-6 from 1,000 Lig/L to 47 (ig/L, and
at TW4-26 from 13 Lig/L to 2 ug/L since pumping began at TW4-4. Concentrations at
these wells have decreased substantially even though they do not appear to be within the
15
N \Requrred Reports\Chlorofbnn Quarterly Monitoring Report\2011 Ql\2011 _Q 1 Chloroform_Report_text doc
hydraulic capture of TW4-4. Pumping TW4-4 acts to cut off the source of chloroform to
these wells by the mechanisms discussed above.
4.2 Review of Analytical Results
4.2.1 Current Chloroform Isoconcentration Map
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: TW4-11, TW4-16, TW4-18, TW4-19, TW4-20,
TW4-22, and TW4-24;
b) Chloroform concentrations have decreased by more than 20% in the following
wells compared to last quarter: TW4-6, TW4-10, MW-26, and TW4-26;
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, and
TW4-21;and
d) TW4-3, TW4-8, TW4-9, TW4-12, TW4-13, TW4-14, MW-32, 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.
Wells TW4-6, TW4-10, TW4-11, MW-26, TW4-16, TW4-18, TW4-19, TW4-20, TW4-
22, and TW4-24, and TW4-26 had changes in concentration greater than 20%. Of the
latter, MW-26, TW4-19 and TW4-20 are pumping wells. TW4-6 is located adjacent to
pumping well TW4-4; TW4-10 and TW4-16 are located adjacent to pumping well MW-
26; TW4-11 is located between pumping wells MW-4 and MW-26; TW4-18 is 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
16
N \Requmed Reports\Chloroform Quarterly Monitonng Report\2011 Ql\20l l_Ql_Chlorofonn_Report_text doc
wells, likely result, in part, from changes in pumping. The increase in concentration at
TW4-24 from 1.4 to 1.8 Lig/L was only slightly greater than 20%, and likely the result of
anaivtical error because the concentration is close to the detection limit. Decreases in
concentrations at TW4-6 and TW4-26 are 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 increased from 24,000 \ig/L to 31,000
Lig/L, the concentration in adjacent pumping well TW4-19 increased from 1,200 ug/L to
3,400 ng/L, the concentration in nearby well TW4-21 increased slightly from 200 to 230
^ig/L, and the concentration in nearby well TW4-22 increased from 340 ug/L to 1,300
Ug/L. 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 430 ng/L to 47
Lig/L since last quarter, placing the well outside the chloroform plume boundary.
Concentrations at TW4-6 have been on a generally downward trend since initiation of
pumping of TW4-4 in the first quarter of 2010 and have decreased from 1,000 ng/L to 47
ng/L 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. TW4-6 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 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 TW4-6 is demonstrated by
comparing the rate of increase in chloroform at this well to the rate of increase in the
nearest upgradient well TW4-4. Concentrations at TW4-4 increased from non-detect to
more than 2,200 ng/L within only 2 quarters whereas 16 quarters were required for
concentrations in TW4-6 to increase from non-detect to only 81 ng/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 TW4-4. Chloroform migration rates in the vicinity of
recently installed well TW4-26 are also expected to be relatively low due to upgradient
pumping and low permeability conditions.
The chloroform concentration in TW4-16, located immediately downgradient of the
chloroform plume, increased from 3 ng/L to 15 ng/L. Slight expansion and 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 now between TW4-4 and TW4-6 (located just north of southernmost
temporary well TW4-26). Decreases in concentration at both TW4-6 (from 430 ng/L to
47 ng/L) and TW4-26 (from 5.4 ng/L to 2 ng/L) are 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 Chem, Inc. were on site to conduct the first phase of the pump test and collect
the initial two days of monitoring data for MW-4. DUSA personnel have gathered
subsequent water level and pumping data.
Analyses of hydraulic parameters and discussions of perched zone hydrogeology near
MW-4 has been provided by Hydro Geo Chem in a separate report, dated November 12,
2001, and in the May 26, 2004 Final Report on the Long Term Pumping Test.
Data collected during the quarter included the following:
• 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 January and
March 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
February 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.
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 correct and consistent recording of
measurements.
5.4.1 MW-4
Approximately 76,247 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
3.7 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. During the January 4, 2011 weekly depth
to water and flow measurements it was noted by Field Personnel that the flow meter was
frozen. Additionally, during the February 21, 2011 depth to water and flow
measurements it was noted by Field Personnel that the flow meter needed to be replaced.
Field Personnel returned the following week and collected the measurements indicating
that the flow meter had been replaced.
5.4.2 TW4-19
Approximately 454,608 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 7.5 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.
5.4.3 MW-26
Approximately 55,130 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
5.3 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 January 4, 2011 weekly depth
19
N \Required Reports\Chbrofbrm Quarterly Monitonng Report\2011 Ql\201 l_Ql_Chlorofbnn_Report_text doc
to water and flow measurements it was noted by Field Personnel that the flow meter was
slow due to the cold weather. During the January 17, 2011 weekly depth to water and
flow measurements it was noted by Field Personnel that the power was off to wells MW-
26 and TW4-20. Field Personnel returned the following week and collected the
measurements after the power had been restored.
5.4.4 TW4-20
Approximately 37,187 gallons of water were pumped from TW4-20 during the quarter.
The average flow rate from TW4-20, when the pump was pumping, was approximately
6.7 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
specifically for that purpose. During the January 17, 2011 weekly depth to water and
flow measurements it was noted by Field Personnel that the power was off to wells MW-
26 and TW4-20. Field Personnel returned the following week and collected the
measurements after the power had been restored. During both the February 7, 2011 and
the February 14, 2011 weekly depth to water and flow measurements it was noted by
Field Personnel that the flow from the pump was slow. Repeat daily inspections on
February 15, 2011 and February 16, 2011 indicated there was a potential issue with the
pump. On February 16, 2011 the pump was replaced and the sealant on electrical
connections was allowed to set. On February 17, 2011 the new pump was turned on but
would not run for more than a few seconds. Upon observing that the new pump was not
performing properly on February 17, 2011, the Mill environmental personnel removed
and inspected the pump and discharge hose, noting that the hose as well as the new pump
were now plugged with fines from the underground formation. New, larger tubing was
ordered for the pump and the well was surged and bailed on February 21, 2011 by a
drilling subcontractor. The well was repaired and put back into operation by 3:00pm on
Monday February 21, 2011. Detailed descriptions of this incident are included in the
notification letter from DUSA to UDEQ dated February 22, 2011.
5.4.5 TW4-4
Approximately 73,360 gallons were pumped from TW4-4 during the quarter. The
average flow rate, when the pump was pumping, was 7.9 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 554.3 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 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 Nitrate Levels
Identification and Definition of the Problem
Rinsate Nitrate Levels
DI water used for decontamination does not show the presence of nitrate. Contamination
does not appear to be related to the nitrate presence in the preceding well that was
purged. Rinsate blank samples following high concentration wells appear to be the same
as rinsate blank samples following low concentration wells. Rinsate blank samples
following purging of uncontaminated wells appear to also be contaminated with nitrate.
Presence of nitrate in the rinsate blank samples is not consistent from one sampling event
to the next.
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 Blank Sample Nitrate Levels
To address the nitrate contamination, DUSA has investigated the potential sources of
nitrate contamination. Nitrile gloves were removed from the rinsate collection process to
21
N VRequmed Reports\ChIoroform Quarterly Monitonng Report\2011 Q1N20I l_Ql_Chlororbrm_Report_text doc
eliminate the potential for mobilizing nitrogen compounds present in nitrile gloves
(possibly caused by leaching of nitrogen from the gloves by the nitric acid). In an effort
to address the nitrate contamination, DUSA has reviewed the entire rinsate collection
process and has made additional changes in an attempt to eliminate the source of the
nitrate in the rinsate sample blanks. These additional changes are discussed below.
In addition, DUSA has requested in the revised QAP, submitted June 4, 2010, the
removal of the nitric acid rinse step when samples are not collected for heavy metals,
which will effectively remove the source of nitrate. DUSA will proceed with the removal
of that step only upon approval of the QAP revision.
Determination of a Corrective Action to Eliminate the Problem
Rinsate Blank Sample Nitrate Levels
The nitrate source is most likely the nitric acid rinse used during decontamination
procedures; however, additional conditions which may be contributing to the nitrate
detections in the rinsate blank samples are being investigated. The additional items for
investigation last quarter included replacement of all of the non-stainless steel portions of
the purging equipment including the pump tubing and connectors. Based on low level
detections this quarter, the replacement of the non-stainless steel portions of the sample
train was not successful. Additional corrective actions to be implemented as a result of
this quarter's exceedances includes the addition of an additional DI rinse to the
decontamination process. Currently, the decontamination process is to pump 50 gallons
of nitric acid, followed by pumping 50 gallons of soap/DI water and lastly pumping 50
gallons of DI water. During the Q2 2011 event a second 50 gallon rinse with DI water
will be added. The rinsate blank will be collected from the second DI rinsate water after
the second 50 gallons of DI are pumped.
Assigning and Accepting Responsibility for Implementing the Corrective Action
Rinsate Blank Sample Nitrate 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 Nitrate Levels
Nitrate sources will be removed after the removal of the nitric acid rinse from the
decontamination procedure when heavy metals are not collected (assuming requisite
changes to the QAP submitted June 4, 2010 are approved by the Executive Secretary).
Additive effects from the nitric acid in the decontamination/rinsate procedure will be
evaluated. To eliminate the cross contamination of the DI water from the nitric acid an
additional rinse of the pump will be conducted.
22
N \Required ReportsVChloroform Quarterly Monitonng Report\20l 1 Ql\201 l_Ql_Chloroform_Report_textdoc
Verifying That the Corrective Action Has Eliminated the Problem
Verification of the contribution from the purging equipment will be completed after the
second quarter 2011 samples have been collected using the decontamination process and
the data have been reviewed. If nitrate contamination persists then additional sources
will be researched and the investigation will continue. Removal of the nitric acid from
the decontaniination procedure will be completed after the Executive Secretary's
approval of the June 4, 2010 QAP revision is received.
6.2 Assessment of Previous Quarter's Corrective Actions
The fourth quarter 2010 report identified corrective actions for nitrate contamination in
the rinsate blank samples. Nitrate contamination continues to be present in the rinsate
blank samples and the investigation to determine the source of nitrate and the associated
corrective actions are described above.
7.0 CONCLUSIONS AND RECOMMENDATIONS
The water level contour maps for the first 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 develop in the vicinity of this well.
Furthermore, the capture zone associated with TW4-4 may be less apparent because of
the low water level at adjacent well TW4-14. However, decreases in chloroform
concentrations at TW4-6 and TW4-26, located downgradient of TW4-4, are 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 TW4-6, TW4-10, TW4-11,
MW-26, TW4-16, TW4-18, TW4-19, TW4-20, TW4-22, and TW4-24, and TW4-26; the
concentration in well TW4-16 increased from 3 fig/L to 15 ug/L and the concentration in
well TW4-24 increased from 1.4 ng/L to 1.8 ng/L.
Of the wells showing changes in concentration greater than 20%, MW-26, TW4-19, and
TW4-20 are pumping wells. TW4-6 is located adjacent to pumping well TW4-4; TW4-10
and TW4-16 are located adjacent to pumping well MW-26; TW4-11 is located between
pumping wells MW-4 and MW-26; TW4-18 is 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 results in
part from changes in pumping. Fluctuations in concentration at well TW4-16, located
immediately downgradient of the chloroform plume, likely result from slight expansion
and contraction of the chloroform plume boundaries in response to changes in upgradient
pumping. Between the current and previous quarters, the concentration in TW4-26, which
is the most downgradient temporary well, decreased from 5.4 Lig/L to 2 ng/L.
23
N \Reqiured RcportsVChloroform Quarterly Monitonng Report\2011 Ql\201 l_Ql_Chloroform_Report_tert doc
The highest chloroform concentration was detected at pumping well TW4-20. Between
the current and previous quarters, the chloroform concentration in TW4-20 increased
from 24,000 ug/L to 31,000 ng/L, the concentration in adjacent pumping well TW4-19
increased from 1,200 ng/L to 3,400 ng/L, the concentration in nearby well TW4-21
increased slightly from 200 to 230 ng/L, and the concentration in nearby well TW4-22
increased from 340 ng/L to 1,300 ng/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 TW4-
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
1.8 ug/LatTW4-24.
The chloroform concentration at well TW4-6 decreased substantially from 430 ng/L to
47 ng/L since last quarter, placing the well outside the chloroform plume boundary.
TW4-6 remained outside the plume between installation in the second quarter of 2000
and the fourth quarter of 2008. Although fluctuations in concentrations have occurred,
this well 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. Decreases in concentrations at TW4-6 and TW4-26
since the last quarter are likely the result of upgradient pumping, in particular pumping at
TW4-4. Chloroform remained non-detect at downgradient temporary well TW4-23.
TW4-23 and TW4-6 (with a chloroform concentration of 47 ng/L) 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 TW4-4 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 1,000 ng/L to 47 ng/L since the first quarter of
2010 is likely related to pumping at TW4-4.

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

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.
