Laboratory Results -- Routine Groundwater Monitoring
2.3.1 Copy of Laboratory Results
A1l analytical results are provided by Energy Laboratories, the Mill's contract analytical
laboratory (the "Analytical Laboratory). There are three sets of laboratory analytical
results included in this Report.
o Samples collected for the July accelerated sampling were reported on August 24,
2007 (Tab E) Also included under this Tab are the results of analyses for a field
blank (Mw-60, 7124107), a rinsate sample from the sampling pump (Mw-63,
7124107) and a duplicate sample of MW-26 (MW-65, 7124107).
o Samples collected in August (8127/07 through 8l3OlO7) for the 3d Quarter and
Accelerated Quarterly samples under the Permit were reported on September 20,
2007 (Tab G). Also included under this tab are the results of analyses for a field
blank (MW-60, 8129107), a rinsate sample of the groundwater sampling pump
(MW-63, 8l29l}7) and a duplicate sample of MW-19 (MW-70, 8130107).
. Samples collected for the September accelerated sampling were reported on
October g,2OO7 (Tab F). Also included under this tab are the results of analyses
for a field blank (MW-60, 9125107), a duplicate sample of MW-26 (MW-65,
el2sll07).
Note: Copies of laboratory QA/QC Summaries are included with the reported data
in corresponding Tabs E, F and G.
2.3.2 Analvsis 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:

Juan County Utah,Intera Inc, 2006) was transmitted to UDEQ on Decembet 29,2006.
This report is under review by UDEQ at the time of this writing and DUSA is responding
to certain information requests generated by UDEQ's consultant URS. In addition to the
background report for existing wells, DruSA has transmitted to UDEQ two addenda to
the -background report, Eialuation of Available Pre-Operational and Regional
Backgrouid Data (Intera, 4llgl07) and Background Groundwater quality Report, New
Welli, For the Denison Mines (USA) Corp. Wite Mesa (Jranium Mill Site, San Juan
County, Utah (Intera,611107). Until such time as background is established, the Permit
requirls 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:
Table 1- GWCL Exceedances for the Quarter
A separate Notice of these exceedances has been submitted to the Executive Secretary
concurrently with the submission of this Report, pursuant to Part I.G.1.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,
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, trAW-Z+, MW-25, MW-21, 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
re[orteA to UDEQ under the title Background Groundwater quality Report, New Wells,
Fir the Denison Mines (USA) Corp. White Mesa (Jranium Mill Site, San Juan County,
Utah (Intera,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 Quartir exceed any Permit limits for any constituents in those wells.
2.4 Labor atory Res ults - Accelerated Monitorin g
The analytical results for the accelerated monitoring of t4e various constituents in certain
monitoring wells for the month June, 2007 and for the 2'd Quarter of 2OO7 are included in
the analytical results for that Quarter under Tabs G and H. The accelerated monitoring
results for November and December, 2006 are included under Tabs E to G, respectively.
The following table summarizes the initial sample result that triggered accelerated
monitoring foi each of the various constituents and the accelerated monitoring results to
date.

DUSA will, however, continue accelerated monitoring of the foregoing constituents until
advised otherwise by the Executive Secretary.
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 was recorded during the Quarter, 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.
2.6 Quality Assurance Evaluation And Data Validation
euality 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) July Sampling:
-One field blank (MW-60, 7124107);
-One duplicate sample of MW-26 (MW-65, 7124107)
-One equipment rinsate sample (MW-63, 7124107 and;

b) August SamPling:
-One field blank (MW-60, 8129107);
-One duplicate sample of MW-26 (MW-65, 8129107,);
-One equipment rinsate samples (MW-63, 8129107); and;
-One trip Utunt provided by the Analytical Laboratory and sent with the samples
received by the Analytical Laboratory on8129107.
c) September SamPling:
-One field blank (MW-60, 9125107);
-one duplicate sample (MW-65, duplicate of MW-26 9125107); and;
-One trip blank prorrid"d by the Analyticat Laboratory and sent with the samples
received by the Analytical Laboratory on9127107.
These eC 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
control/quality assurance (QA/QC) measurernents 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 MillOA Manaeer Review
The Mill eA 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 FielilQCitrects; 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 implemented.

" ,// * auoii"ut" Mw-6llndicated acceptable duplication of analytical results except for
,// t\rnang1n"""ffinQra chloroform where the RPD's were 33.04,31.14 and 26.80
for thelil#situ#, respectively. In addition, the field blank sample indicated the
minor presence of chloroform.
In accordance with Section 10.1 of the Groundwater Monitoring Quality Assurance
Plan (QAP), the acetone, chloroform and manganese parameters are annotated here
as faliing outside of the QA specification for duplicate samplings. Denison has
initiated the process to determine the root cause for duplication difficulties through
extended discussions with the Laboratory and the Denison sampling technicians'
While these duplicate samplings were outside of the 20% RPD specificatior\ an
improvement of approximately 10% is noted. Denison is in the process of preparing
a report on the splcific steps to resolve these problems(s) in accordance with the
procedure set forth in Section 10.2 of the QAP'
(ii) August sampling * dN,*nlc t u,l,,t/t (a, N)
The results of duplicate QC checks for the August sampling indicated was greatly

(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:
Laboratory fortified blanks are equivalent to laboratory control spikes,
laboratory reagent blanks are equivalent to method blanks, post
digestionspikes 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
were reviewed bY the QA Manager.
The QA Manager noted that:
Some ,,D,, qualifiers (reporting limit increased due to matrix interference) were
observed foi sulfate, chloroform and in one instance sodium. Sulfate limits have
not been established and none of the detection limit modifications made in
response to interferences were above permit limitations for those parameters.

(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, attesting to the precision and accuracy of the measurement methods.
The temperature of the samples was found to be acceptable upon delivery to the
Laboratory and holding times were adhered to during transit to the Laboratory.
A review of the surrogate spiked samples for each sample showed no qualifiers
In addition, all percent recoveries were within tolerance limits assuring the
accuracy of the analytical methods employed.
2.7 Electronic Data Files and Format
DUSA has provided to the Executive Secretary an electronic copy of all laboratory
results for groundwater quality monitoring conducted during the Quarter in Comma
Separated Values (CSV). A copy of the transmittal e-mail is included under Tab I.
