quarterly and semi-annual monitoring efforts, regardless of the sampling
purpose.
Field Data Sheets
Attached under Tab B are copies of all field data sheets where field data were
recorded in association with the quarterly effort on Nov. 4-13,2008 for the
groundwater compliance monitoring wells listed in paragraph 2.1(a) above.
Attached under Tab C are copies of all field data sheets where field data were
recorded in association with monthly accelerated monitoring and sampling
efforts during the month of October for monitoring wells; MW-14, MW-26
and MW-32.
Attached under Tab D are copies of all field data sheets where field data were
recorded in association with monthly accelerated monitoring and sampling
efforts during the month of December for monitoring wells; MW-14, MW-26
and MW-32.
Laboratory Results -- Routine Groundwater Monitoring
Coov of Laboratorv Results
All analytical results are provided by Energy Laboratories, the Mill's contract analytical
laboratory (the "Analytical Laboratory). There are four sets of laboratory analytical
results included in this Report.
Samples collected for the October accelerated sampling were reported on
November 11 and 12,2OO8 (Tab E) Also included under this Tab are the results of
a duplicate sample of MW-32 (MW-65, 10-13-08). Because the wells in the
GWDP sampling program have been equipped with dedicated pumps since the
November, 2007 sampling, a rinsate sample is no longer collected. An analysis of
a field blank was included with the monthly sampling (Mw-60, 10-14-08).
Samples collected for the December accelerated sampling were reported on
January 5,2009 (Tab F). Also included under this tab are the results of analyses
for a duplicate sample of MW-32 (MW-65, 12-9-08). Because the wells in the
GWDP sampling progritm had been equipped with dedicated pumps for the
November,2}}7 sampling, a rinsate sample is no longer collected. An analyses
of a field blank was included with the monthly sampling (MW-60, 12-11-08).
Samples collected for the 4ft Quarter and Accelerated Quarterly samples under the
Permit were reported in three data sets dated December 6, 11 and 31, 2008 (Tab
G). Also included under Tab G are the results of analyses for duplicate samples of
MW-32, and MW-22. (MW-65, 11-5-08 and MW-70, I t-12-08, respectively). A
field blank was collected for the quarterly sampling episode (MW-60, 11-13-08).
Note: Copies of laboratory QA/QC Summaries are included with the reported data
at corresponding Tabs E, F and G.
2.3.2 Analysis of Laboratory Results
Under the Permit it is intended that background groundwater quality will be determined
on a well-by-well basis, as defined by the mean plus second standard deviation
concentration. The Mill is currently in the process of working with the Utah Division of
Radiation Control and its consultant URS to establish background (including the mean
plus second standard deviation) for all of the constituents being sampled under the
Permit. Toward this end, a report entitled Background Groundwater Quality Report:
Existing Wells For Denison Mines (USA) Corp.'s White Mesa Uranium mill Site, San
Juan County rJtuh,Intera Inc, 2006) was transmitted to UDEQ on December 29,2006.
In response to UDEQ's review, a revised report was provided to UDEQ on October 2007,
Revised Background Groundwater Quality Report: Existing Wells For Denison Mines
(USA) Corp.'s White Mesa (Jranium mill Site, San Juan County Utah,Intera Inc, 2007.
In addition to the background report for existing wells, DUSA has transmitted to UDEQ
two addenda to the background report, Evaluation of Available Pre-Operational and
Regional Background Data (Intera, 4ll9l07) ard Background Groundwater quality
Report, New Wells, For the Denison Mines (USA) Corp. White Mesa Uranium Mill Site,
San Juan County, Utah (Intera, 611107). Finally, in response to comments provided by
UDEQ, Denison issued a revised Addendum to the Report Background Groundwater
quality Report, New Wells, For the Denison Mines (USA) Corp. White Mesa Uranium
Mill Site, San Juan County, Utah on April 30, 2008 Until such time as background is
established, the Permit requires that constituent concentrations in each monitoring well
shall not exceed the Groundwater Compliance Limits ("GWCLs") set out in Table 2 of
the Permit.
DUSA's review of the analytical results for the Quarter indicates that concentrations of
the following constituents in the following monitoring wells exceeded their respective
GWCLs in Table 2 of the Permit:

A separate Notice of these exceedances has been submitted to the Executive Secretary on
January s,z}Og,pursuant to Part I.G.l.a) of the Permit.
Unless the compliance status for any constituents in any wells is determined otherwise by
the Executive Secretary, the Mill will, pursuant to Part I.G.l.b)l) of the Permit,
commence or continue, as the case may be, accelerated sampling of each of the foregoing
constituents in its respective well on a monthly or quarterly basis, as applicable, as set
forth below:

The background constituent concentrations for all of the new monitoring wells (MW-3A,
MW-23, MW-24, MW-25, MW-27, MW-28, MW-29, MW-30 and MW-31) through
eight quarters of sampling pursuant to Part I.H.4 of the Permit has been evaluated and
reported to UDEQ under the title Background Groundwater quality Report, New Wells,
For the Denison Mines (USA) Corp. Wite Mesa (Jranium Mill Site, San Juan County,
Utah (Intera, 611107) and its April 30, 2008 Addendum. This report is currently under
review at UDEQ and, as such, the GWCLs for these wells have not been determined and
included in the Permit. Accordingly, it is premature to determine whether or not any of
the sampling results for this Quarter exceed any Permit limits for any constituents in
those wells.

2.5 Depth To Groundwater Readings And Water Table Contour Map
A listing of groundwater level readings for the Quarter (shown as depth to groundwater in
feet) is included under Tab H.
Also included under Tab H is a water table contour map, which provides the location and
identity of all of the wells and piezometers listed in items 2.1(b) above for which depth to
groundwater is recorded. The groundwater elevation at each well and piezometer,
measured in feet above mean sea level, and isocontour lines to delineate groundwater
flow directions observed during the Quarter's sampling event is displayed on the map.
2.6 Quality Assurance Evaluation And Data Validation
Quality assurance evaluation and data validation procedures in effect at the time of
sampling were followed. These involve three basic types of evaluations: field QC
checks; Analytical Laboratory QA checks; and checks performed by DUSA personnel, as
described below.
2.6.1 Field OC Checks
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:
a) October Monthly Accelerated Sampling:
-One duplicate sample of MW-32 (MW-65, collected 10/13/0S)
-One field blank (MW-60, collected l0ll4l08)
-One trip blank provided by the Analytical Laboratory and sent with the samples
received by the Analytical Laboratory on l0/15/08.
b) December Monthly Accelerated Sampling:
-One duplicate sample of MW-32 (MW-65, collected l2l09l0S)
-One field blank (MW-60, collected 12109108)
-One trip blank provided by the Analytical Laboratory and sent with the samples
received by the Analytical Laboratory on l2llll08.
c) NovemberQuarterly/Accelerated Sampling:
- Two duplicate samples of MW-32 and MW-17 (MW-65 & MW70,
collected I I / 5 / 08 and I | / l2l 08, respectively)
- One field blank (MW-60, collected 11/13/0S)
-Three trip blanks provided by the Analytical Laboratory and sent with the

samples received by the Analytical Laboratory on 1 1/6/08 , lll7l08 and I 1/14108.
These QC samples were sent blind to the Analytical Laboratory and analyzed for the
same parameters as permit-required samples.
2.6.2 Analytical Laboratory OA/OC Procedures
The Analytical Laboratory has provided summary reports of the analytical quality
controVquality assurance (QA/QC) measurements necessary to maintain conformance
with 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 Tabs E to G.
2.6.3 Mill OA Manager Review
The Mill QA Manager, which for the purposes of this Report was DUSA's Manager of
Environmental Affairs, performed three types of reviews: a determination of whether
Mill sampling personnel followed Mill sampling procedures; a review of the results from
the Field QC Checks; and a review of the Analytical Laboratory QA/QC analysis. The
results of the QA Manager's review are discussed below.
a) Adherence to Mill Sampling SOPs
On a review of adherence by Mill personnel to the existing sampling standard
operating procedures (SOPs), the QA Manager observed that QA/QC requirements
established in the Groundwater Monitoring Quality Assurance Plan were being
adhered to and that the SOP's were implernented.
I. Resultsfromfield QC checks
(i) October Sampling
The results of duplicate QC checks for the October sampling indicated that the
duplicated samples were within the Relative Percent Difference goal of 20Yo (see
Table 4). The information from the Laboratory QA/QC Summary Report indicates
that RPD and recovery data at the Laboratory were within acceptable limits as well.
There were no qualifications attached to these data by the laboratory. A11 samples
were received within acceptable temperature specification and holding time
requirements were adhered to.

(iii) Novernber (Quarterly/Accelerated) Sampling
The results of duplicate QC checks for the quarterly sampling indicated that one of
the Relative Percent Difference (RPD) value's minimally exceeded the 20% RPD
standard (i.e Thallium, MW-17 vs MW-70 RPD : 24.79%). Values for cadmium,
iron and, zinc in the MW-70 duplicate sample indicated trace amounts of those metals
while the original MW-32 sample yielded less than detectable concentrations for
those constituents (See Table 6). Well MW-65, the duplicate for well MW-32
indicated a trace amount of Tetrahydrofuran just above the detection limit, whereas
the original sample showed THF at less than the detection limit. This is a marked
improvement over previous periods during 2008 (i.e. l't Quarter data indicated ll
instances where the RPD value exceeded 20%).In addition, all sample sets sent to
Energy Labs and AWAL were received within the current 4o C limit for acceptance.

c) Review of Analytical Laboratory QA/QC Analysis
The QA Manager reviewed the Analytical Laboratory's QA/QC Summary Reports and
made the following conclusions;
25
Carbonate as CO3. Bicarbonate as HCO3
Nitroeen. Nitrate + Nitrite as N

Check samples were analyzed for all methods used in analyzing the
groundwater samples. These methods were:
Table 7 - Analytical Methods Utilized
(ii) The check sunples included at least the following: a method blank, a laboratory
control spike, a matrix spike and a matrix spike duplicate, or the equivalent,
where applicable. In this context, it should be noted that:
Laboratory fortified blanks are equivalent to laboratory control spikes,
laboratory reagent blanks are equivalent to method blanks, post
digestion spikes are equivalent to matrix spikes and post digestion
spike duplicates are equivalent to matrix spike duplicates; and
For method E900.1, used to determine gross alpha, a sample duplicate
was used instead of a matrix spike duplicate;
(iii) All qualifiers, and the corresponding explanations reported in the QA/QC
Summary Reports for any of the check samples for any of the analytical
methods were reviewed by the QA Manager.
With regard to laboratory qualifiers, there were some instances where a
reporting limit (RL) was increased due to matrix interference, however, in these
cases the reported value was well above the re-established RL or, in those
instances where the result was less than the re-established RL, the RL was still
less than the GWCL.
(vi) The information from the Laboratory QA/QC Summary Reports indicate that
RPD at the Laboratory were primarliy within acceptable limits. However, there
were instances where spike recovery and RPD data fell slightly outside of the
stated limits.

Corrective Actions
During the 3'd Quater report period it was noted that field bla* de-ionized water
continued to yield trace volatile organic presence (i.e. Chloroform). This matter
was further investigated by the QA manager and corrective measures included:l) a confirmation that purchased de-ionized water had in fact been used for thefield blank and, 2) two sets of 3 purchased de-ionized waters samples were
prepared and duplicate sets were sent to each of two contract laboratories(Energy Lab and AWAL). Both Labs continued to report the presence of lowconcentration Chloroform in all of the purchased water samples (e.g.
approximately 30 ppb). Concurrently, these low concentrations of ihloroform
were found in the 4* Quarter field blanks as well. During the QA review for the
preparation of this report it was discovered that in fact what was purchased is the
resin used to treat the water, and not the water itself. Accordingly, for the lrt
Quarter, 2009 samples of pretreated water, treated water and the field blanks
themselves will be analyzed to further isolate the cause of this low level
contaminant source.
Electronic Data Files and Format
DUSA has provided to the Executive Secretary an electronic copy of alllaboratory results for groundwater quality monitoring conducted during the
Quarter in Comma Separated Values (CSV). A copy of the transmittal e-mail is

All original sample submittals have been retumed 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 ctrilling 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 bythis 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 expdsure tobeginning ofcounting should not exceed 8 days.

CASE NARRATIVE
oRIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been retumed with the data package.
SAMPLE TEMPERATURE COMPLIANCE: a"C (t2"C)
i"rp"otrp of samples received may not be coirsideied properly pregerved by accepted standards...Samples that are hand
detiv'ered immediateiy after collection -snatt
Oe considered acceptable if there is evidence that the chilling process has begun.
GROSS ALPHA ANALYSIS
fr4ettrod 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 ]N AIRANALYSIS
The desirea 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 ofcounting should not exceed 8 days.
SOIUSOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS USING EPA 505
Data for Atrazine and Simazine are reported from EPA 525.2, not from EPA 505. Data reported by ELI using EPA method
50S reflects the resutd for seven individual Aroclors. When the results for all seven are ND (not detected), the sample
meets EPA compliance criteria for PCB monitoring'
SUBCONTMCTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. lf so, ENERGY LABOMTORIES will utilize its
branch laboralories or qualified contract laboratories for this service. Any such laboratories will be indicated within the

Sampte Delivery GrouP: C08110216
oRIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4'C (t2"G)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are hand
delivered immediateiy after colleclion shall be considered acceptable if there is evidence that the chilling prooess has begun.
GROSS ALPHA ANALYS]S
Method S)0.0 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 expoeure 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 re@mmended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIUSOLID SAMPLES
All samples reported on an as received basis unless othenrise indicated.
ATRMINE, SIMAZINE AND PCB ANALYSIS USING EPA 505
Data for Atrazine and Simazine are reported from EPA 525.2, not from EPA 505. Data reported by ELI using EPA method
505 reflec{s the results for seven individual Aroclors. \Mren the results for all seven are ND (not detected), the sample
meets EPA compliance criteria for PCB monitoring.

oRrcr NAL SAMPLE SUBMTTTAL(S)
All original sample submittals have been retumed with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4"C (t2'C)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are handdelivered 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 bythis method for non potable waters should be viewed as inconsistent.
MDON INAIRANALYSIS
The desked exposure time.is.48 hours (2 days). The time delay in returning the canister to the laboratory for processingshould,be as short.as possible to avoid excessive decay. Maximum recommended delay between end of expisure tobeginning of counting should not exceed 8 days.
SOIUSOLID SAMPLES
All samples reported on an as received basis unless othenrrrise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS USING EPA 505
Data for Atrazine and Simazine are reported from EPA 525.2, not from EPA 505. Data reported by ELI using EpA method505 reflects the resuftdfor seven individual Aroclors. ll/tren tire results for all seven are ND (not detected), the samplemeets EPA compliance criteria for PCB monitoring.
