quarterly and semi-annual monitoring efforts, regardless of the sampling
purpose.
2.2 Field Data Sheets
Attached under Tab B are copies of all field data sheets where field data were
recorded in association with the quarterly and semi-annual sampling effort on
October 23 through October 31, 2007 for the groundwater compliance
monitoring wells listed in paragraphz.l(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 November 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 Decernber for monitoring wells; MW-14, MW-26
and MW-32.
2.3 Laboratory Results -- Rout'ne Groundwater Monitoring
2.3.1 Copy of Laboratory 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 November accelerated sampling were reported on
January 2, 2008 (Tab E) Also included under this Tab are the results of a
duplicate sample of MW-26 (MW-65, lll28l07). Because the wells in the GWDP
sampling program had been equipped with dedicated pumps by the November
sampling an equipment rinsate sample was no longer necessary as of November,
2007. An analyses of a field blank was not included with this sample set.
o Samples collected for the December accelerated sampling were reported on
January 7, 2008 (Tab F). Also included under this tab are the results of analyses
for a duplicate sample of MW-26 (MW-65, l2ll8l07). Because the wells in the
GWDP sampling program had been equipped with dedicated pumps an equipment
as of the Novernber, 2008 sampling, rinsate sample was no longer necessary in
December. An analyses of a field blank was not included with this sample set.
. Samples collected in October (l0l23lo7 through lOl3llOT) for the 4rth Quarter and
Accelerated Quarterly samples under the Permit were reported in two data sets on
January 9, 2008 and received by Denison on January 14,2008 (Tab G). Also

Note: Copies of laboratory QA/QC Summaries are included with the reported, data
in 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 determinedon 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 ofRadiation Control and its consultant URS to establish background (including the meanplus second standard deviation) for all of the constituents b"ing'sampletunder thePermit. Toward this end, a report entitled Background Groundwater Quality Report:Existing Wells For Denison Mines (USA) Corp.'s White Mesa Uraniui mill Site, SanJuan County Utah, lntera lnc, 2006) was transmitted to UDEe on Decemb er 29, 2006.
In response to UDEQ's review, a revised report was provided to UDEe on Octob jr 2007,
Revised Background Groundwater Quality Report: Existing Wells For Denison Mines(USA) Corp.'s White Mesa (Jranium mill Site, San Juan County (Jtah, lntera Inc, 2007.In addition to the background report for existing wells, DIUSA Las transmitted to UDEetwo addenda to the background report, Evaluation of Available Pre-Operational andRegional Background Data (Intera, 4ll9/07) and Background Grouidwater quality
Report, New Wells, For the Denison Mines (USA) Corp. White Mesa (Jranium Afu Siti,
San Juan County, Utah (Iutera, 6/1107). Until such time as background is established,the Permit requires that constituent concentrations in each moniioring well shall notexceed the Groundwater Compliance Limits ("GWCLs") set out in Tablel of the permit.
DUSA's review of the anallical results for the Quarter indicates that concentrations ofthe 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
February 13, 2008, 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.1.b)1) of the Permit,
coflrmence 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. White Mesa (Jranium Mill Site, San Juan County,
Utah (lntera, 611107). 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.

2.6 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 Sampling:
-One field blank (MW-60, 10130107);
-Two duplicate samples of MW-26
(MW-65 and MW-70,1012108 & 10/30/08, respectively)
-One equipment rinsate sample (MW-63, 10130107 and,
-One trip blank provided by the Analytical Laboratory and sent with the samples
received by the Analytical Laboratory on 10126107.
b) November Sampling:
-One duplicate sample of MW-26 (MW-65, lll28l07,) and;
-One trip blank provided by the Anallical Laboratory and sent with the samples
received by the Analytical Laboratory on lll30/07.
c) December Sampling:
-One duplicate sample (MW-65, duplicate of MW-26 ); and;
-One trip blank provided by the Analytical Laboratory and sent with the samples
received by the Analytical Laboratory on 12120/07.
Note: For monthly accelerated sampling in Novernber and December an equipment
rinsate sample was not collected as these wells were equipped with dedicated pumps
subsequent to the October quarterly sampling event. Due to a miscommunication a field
blank was not included with the monthly sample batches, albeit field blanks are not
required by either the GWDP or the QAP and are collected voluntarily by DUSA. The
Environmental staff at the mill has been apprised of this oversight and will include a field
blank with all monthly and quarterly samplings for future monitoring periods.
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 QA/OC Procedures
The Analytical Laboratory has provided summary reports of the analytical quality
control/quality assurance (QA/QC) measurements necessary to maintain conformance
with NELAC certification and reporting protocol. The Analytical Laboratory eA/eCSummary 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 QA 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 whetherMill 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 wire being
adhered to, (except that the field blanks were not included with the monthly
samplings as mentioned above) and that the Sop's were implemented.
b) Results fromfield QC checks
(i) October Sampling
The results of duplicate QC checks for the October sampling indicated three
exceptions to the Relative Percent Difference goal of 2Ooh. The MW-26 sample and
its duplicate MW-65 indicated acceptable duplication of analytical results except for
nitrogen-ammonia, iron, selenium, uranium and gross alpha. Ho*",n"r, the results of
the MW-4 and its duplicate MW-70 were all well within the acceptance criteria. The
results of the Field Blank, Rinsate Sample and the evaluation of duplicate analyses
are presented in the Table below.

* RPD Equation for Gross Alpha Satisfied if differential analysis of reported values and counting error is <2
In accordance with Section 10.1 of the Groundwater Monitoring Quality Assurance
Plan (QAP) the nitrogen-ammonia, iron, selenium, uranium and gross alpha
parameters are annotated here as falling outside of the QA specification for duplicate
samplings. Denison has previously initiated a process to determine the root cause for
duplication difficulties through extended discussions with the Laboratory and the
Denison sampling technicians. While some duplicate analyses for MW-26 were
outside of the 20% RPD specification, the results of duplicate analyses for MW-4
were all within specification. With regard to duplicate sampling of MW-26, this
well is a pumping well and is subject to fluctuation in chemical parameters while
sampling is underway. In accordance with Section 10.2 of the QAP Denison
determined that duplicate analyses for MW-26 should be discontinued and that this
pumping fluctuation is the root cause in failing RPD's on duplicate analyses for this
well.

(ii) November Sampling
The results of duplicate QC checks for the November sampling indicated that
manganese and methylene chloride exceeded the Relative Percent Difference goal of
20%. With regard to duplicate sampling of MW-26, this well is a pumping well andis subject to fluctuation in chemical parameters while sampling is underway. In
accordance with Section 10.2 of the QAP Denison determined that duplicate analyses
for MW-26 should be discontinued and that this pumping fluctuation is the root cause
for failing RPD's on duplicate analyses for this well.
As noted at2.6.l a) above, due to a miscommunication a field blankwas not included
with the monthly sample batches. Rinsate samples were not required due to the use
of dedicated pumping equipment. The Environmental staff at the mill have been
apprised of this oversight and will include a field blank with all monthly and quarterly
samplings for future monitoring periods.

sample batches. Rinsate samples were not required due to the use of dedicated
pumping equipment The Environmental staff at the mill have been apprised of this
oversight and will include a field blank with all monthly and quarterly samplings for
future monitoring periods.

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;
(i) Check samples were analyzed for all methods used in analyzirrg the
groundwater samples. These methods were:
Table 8 - Analytical Methods Ut:lized
(ii) The check samples 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:
o Laboratory fortified blanks are equivalent to laboratory control spikes,
laboratory reagent blanks are equivalent to method blanks, post
Carbonate as CO3. Bicarbonate as HCO3
Nitrate + Nitrite as N

digestion spikes are equivalent to matrix spikes and post digestion
spike duplicates are equivalent to matrix spike duplicates; and
o 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.
Some "D" qualifiers (reporting limit increased due to matrix interference) were
observed for sulfate, chloroform and sodium. Sulfate limits have not been
established under the permit and sodium is not a limited parameter. For
chloroform, none of the detection limit modifications made in response matrix
interference resulted in less than values above the required reporting level.
(iv) A review of the Laboratory QA/QC summary reports indicated that the percent
recovery and spiked duplicate results reported by the laboratory were acceptable
with one exception (MW-14, 10129108 sample surrogate recovery at l32o/o for
1,2 Dibromfluoromethane compared to the RL guidance of 130%) attesting to
the precision and accuracy of the measurement methods.
The QA Manager noted that samples received and accepted by the Laboratory
on November 30, 2008 were recorded at l4o C (but on ice), while all other
samples for this reporting period were within the 4o C guidance. This subject
was addressed in correspondence to UDEQ on February 2T, 2008. Further
instances where samples are received by the laboratory in excess of the
temperature requirement are not expected due to the acquisition of "5-day''
coolers for sample transport.
(v) It was noted by the QA Manager that gross alpha results for MW-l, MW-2,
MW-23, MW-26, NNV-27, MW-28, MW-32 and the MW-26 Duplicate (MW-
65) exceeded2} Yo vaiance for counting effor when compared to the reported
analyical value. However, recent discussions with UDEQ, and corresponding
drafted modifications to the GWDP, will modifii this requirement allowing that
in these instances (<20% counting error) but when the precision effor is added
to the reported value the resulting sum does not exceed the groundwater
compliance limit the variance is acceptable. Accordingly, non-conformance is
not indicated under the proposed modification to the GWDP. Once approved by
UDEQ, these new conformance criteria for Gross Alpha will be incorporated
into the QAP.

THIS IS THE FINAL PAGE OF THE LABORATORY ANALYTICAL REPORT
REVI SED/SUPPLEMENTAL REPORT
The attached analytical report has been revised from a previously submitted report due to the addition of Uranium onsamples MW14 and MW26 per request from Steve Landau 212212A09.
oRr Gt NAL SAMPLE SUBMTTTAL(S)
All original samplesubmittalshavebeenreturnedwiththedatapackage. Acopyofthesubmittal(s) hasbeenincluded
and tracked in 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 arehand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process
has begun.
SOIUSOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
PCB ANALYSIS USING EPA 505
Data reported by ELI using EPA method 505 reflects the results for seven individual Aroclors. When the results for allseven are ND (not detected), the sample meets EPA compliance criteria for PCB monitoring.
SUBCONTRACTI NG ANALYSIS
subcontracting of sample analyses to an outside laboratory may be required. lf so, ENERGY LABoRAToRIES will utilizeits branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within theLaboratory Analytical Report.
