2.1. Samples and Measurements Taken During the Quarter
A map showing the location of all groundwater monitoring wells, piezometers, existing
wells and temporary chloroform contaminant investigation wells is attached under Tab A.
During the Quarter, the following groundwater samples and measurements were taken
during this reporting period (April through June).
a) Groundwater Compliance Monitoring
(i) QuarterlyGroundwaterComplianceMonitoring
Quarterly Groundwater Compliance Monitoring is typically performed in the wells listed
below, pursuant to Part I.E.l. a) of the Permit, However, in accordance with the request
and permission of the UDEQ, samples of wells MW-11 and MW-14 were not collected in
June in order not to disturb the wells prior to the then forthcoming University of Utah
sampling effort.
MW-l1
Ivtw-14
MW-26 (formerly TW4- 15)
MW-32 (formerly TW4- 17)
(ii) S emi-annual Groundwater Compliance Monitoring
Semi-annual Compliance Monitoring is typically performed in the wells listed below,
pursuant to Part I.E.I. a) of the Permit. However, with the exception of MW-17 and in
accordance with the request and permission of the UDEQ, these samples were not
collected in June in order not to disturb the wells prior to the then forthcoming University

(iii) Accelerated Groundwater Monitoring.
In addition to the routine quarterly and semi-annual monitoring referred to above, DUSA
collected accelerated monthly samplings for select constituents at wells: MW-14, MW-26
and MW-32. Accelerated quarterly samples are typically collected at certain locations
and for select constituents at wells: MW-l, MW-3, MW-5, MW-12, MW-15, MW-17,
MW-l8 and MW-19. However, with the exception of MW-17 and in accordance with the
request and permission of the UDEQ, these samples were not collected in June in order
not to disturb the wells prior to the then forthcoming University of Utah sampling effort.
The sample collection dates for monthly samples occurred on April 24 & 25,2007 and
lll4ay 22,2007 . Routine quarterly and accelerated quarterly sample collection occurred on
June 20 &.2I,2007.
(iv) ParametersAnalyzed
All routine groundwater monitoring samples were analyzed for the parameters listed in
Table 2 and. Part I.E.l.c) 2)ii of the Permit. The accelerated monitoring samples were
analyzed for the more limited specific parameters described in Section 2.4 of this report.
b) Groundwater Head Monitoring
Depth to groundwater was measured in the following wells and/or piezometers, pursuant
to Part 1.E.2 of the Permit:
(i)
(iD
(iii)
(iv)
The quarterly groundwater compliance monitoring wells listed in paragraph
2.1.a) above were measured on June 20, 2OO7 .
Piezometers - P-1, P-2,P-3, P-4 and P-5, on June29,2007:
Existing monitoring well MW-4 and all of the temporary chloroform
investigation wells, on May 2,2007;
In addition to the above, depth to water measurements are routinely observed
in conjunction with sampling events for all wells sampled during monthly,
quarterly and semi-annual monitoring efforts, regardless of the sampling
purpose.

b. Laboratory Results -- Routine Groundwater Monitoring
i. CoPy of Laboratorli Results
All analytical results are provided by Energy Laboratories, the Mill's contract analytical
laboratory (the "Analytical Laboratory). There are three sets of laboratory analyical
results included in this Report.
o Samples collected for the April accelerated sampling were reported on May 31,
2OO7 (Tab E) Also included under this Tab are the results of analyses for a field
blank (MW-60, 4l24ll7), a rinsate sample from the sampling pump (MW-63,
4124107) and a duplicate sample of MW-26 (MW-65, 4124107).
. Samples collected for the May accelerated sampling were reported on June 14,
2007 (Tab F). Also included under this tab are the results of analyses for a field
blank (MW-60, 5l22l}7), a duplicate sample of MW-26 (MW-65, 5122107), and a
a rinsate sample collected from the sampling pump (MW-63, 5-22-07).
o Samples collected in June for the 2o" Quarter and Accelerated Quarterly samples
under the Permit were reported on August 2,2007 (Tab G). Also included under
this tab are the results of analyses for a field blank (MW-60, 6121107), a rinsate
sample of the groundwater sampling pump (MW-63, 6121107) and a duplicate
sample of MW-26 (MW-65, 6120107).
Note: Copies of laboratory QA/QC Summaries are included with the reported data
in corresponding Tabs E to 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 Utah, lntera Inc, 2006) was transmitted to UDEQ on December 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, Evaluation of Available Pre-Operational and Regional
Background Data ([ntera, 4ll9l07) and Background Groundwater quality Report, New
Wells, For the Denison Mines (USA) Corp. Whrte Mesa Uranium Mill Site, San Juan
County, Utah (lntera,611107). 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:
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.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,
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:

Note 1: As per a letter from the Executive Secretary dated May 30, 2006, accelerated monitoring for iron
and lead in MW-l I and beryllium and lead in MW-32, was relaxed, and as a result those
constituents are no longer included in this Table.
Note 2: Dichloromethane reported as methylene chloride by the Analytical Laboratory
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 Uranium 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.
c. Laboratory Results - Accelerated Monitoring
The analytical results for the accelerated monitoring of the various constituents in certain
monitoring wells for the month Jwe,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 for each of the various constituents and the accelerated monitoring results to
date.

ruSA will, however, continue accelerated monitoring of the foregoing constituents until
advised otherwise by the Executive Secretary.
d. 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.
e. 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.
i. 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:
1. April Sampling:a. One field blank (MW-60, 4l24lo7);b. One duplicate sample of MW-26
(MW-65,4t24tj7)
c. One equipment rinsate sample (MW-63, 4124107
and;d. One trip blank provided by the Analytical
Laboratory and sent with the samples received by
the Analytical Laboratory on 4126107.

3. June Sampling:
One field blank (MW-60, 6121107);
One duplicate sample
(MW-65, duplicate of MW-26 6120107),
One equipment rinsate sample (MW-63 6121107),
and;
One trip blank provided by the Analyical
Laboratory and sent with the samples received by
the Analytical Laboratory on 6122107.
These QC samples were,sent blind to the Analytical Laboratory and analyzed for the
same parameters as permit-required samples.
ii. Anallrtical 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 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 analyical results
under Tabs E to G.
iii. 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 implemented.
b) Resultsfromfield QC checks
(i)April Sampling
The results of duplicate QC checks for the April sampling indicated two exceptions
to the Relative Percent Difference goal of ZOVo. The MW-26 sample and it's
duplicate MW-65 indicated acceptable duplication of analytical results except for
chloroform and methylene chloride, where the RPD's were 54.5 and 41.46, for these
constituents, respectively. ln addition, the field blank sample indicated the presence
of chloroform (2.0 uEtL) and the equipment rinsate sample indicated acetone at 1
ug/L above the detection limit for that parameter.
ln accordance with Section 10.1 of the Groundwater Monitoring Quality Assurance
Plan (QAP), the chloroform and methylene chloride parameters are annotated here as
falling 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. Denison is in
the process of preparing a report on the specific steps to resolve these problems(s) in
accordance with the procedure set forth in Section 10.2 of the QAP.
(ii) May Sampling
The results of duplicate QC checks for the May sampling indicated two exceptions to
the Relative Percent Difference goal of 20Vo. The MW-26 sample and it's duplicate
MW-65 indicated acceptable duplication of analytical results except for uranium,
where the RPD was slightly in excess of the RPD goal at 2I.4Vo and methylene
chloride which exhibited a 60.57o RPD for that constituent. ln addition, field blank
sample indicated the presence of chloroform at the detection limit (1.0 ug/L) and the
equipment rinsate sample indicated the presence of toluene (1.3 up/L), slightly above
the detection limit of I ug/L for that parameter

(iii) June Sampling
The results of duplicate QC checks for the June sampling were within the
accepted Relative Percent Difference goal of 207o. However, the field blank
indicated chloroform presence at 86 :ugll- and the equipment rinsate sample indicted
the presence of manganese (40 u,gtL), chloroform (7 .9 ugtL) and toluene (slightly
above the detection limit of I ug/L atl.6 ug/L).
General Notation: The field blanks and equipment rinsate samples continue to
indicated some presence of chloroform. In addition, and for this report period,
toluene and acetone were also observed. Because the field blanks consist of de-
ionized water and the equipment is rinsed with this same water source, Denison has
investigated modification of its de-ionized water treatment system. The feed source
to this system is potable water which is chlorinated, possibly contributing to the
generation of trace chloroform in the treated water. As such, Denison has installed
a carbon filtration unit subsequent to the de-ionization process as a polishing step in
the process. ln addition, and because of the presence of manganese, toluene and
acetone was in the equipment rinsate samples, equipment cleaning will also be
reviewed with sampling technicians.
c) Review of Analytical Laboratory QNQC 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 analyzing the
groundwater samples. These methods were:

(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
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.
The QA Manager noted that:
Some "D" qualifiers (reporting limit increased due to matrix interference) were
observed for 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.

(i) DMT PERFORMANCE STANDARD MONITORING
a. Measurements Taken During the Quarter
During the Quarter, the following DMT Monitoring was performed or addressed, as
required under Part I.E.6 of the Permit:
-Weekly tailings wastewater pool elevations for tailings Cells 1 and 3;
-Weekly slimes drain water levels;
-Weekly wastewater level measurements in Robert's Pond; and
-Weekly feedstock storage area inspections.
b. Weekly Tailings Waste Water Pool Elevation Monitoring
Mill personnel monitored and recorded weekly the elevation of wastewater in Tailings
Cells 1 and 3 to ensure compliance with the maximum wastewater elevation criteria
mandated by Condition 10.3 of the Mill's Radioactive Materials License. These
measurements were made from an elevation survey. The results of such monitoring,
reported as feet above mean sea level (fmsl), are included in Tab J.
Condition 10.3 of the Mill's Radioactive Materials License provides that freeboard limits
for Cells 1 and 3 shall be set in accordance with procedures that have been approved by
the U.S. Nuclear Regulatory Commission. Under those procedures:
(i) The freeboard limits are set as per the January 10, 1990 Drainage Report for Cell
I at a liquid maximum elevation of 5,615.4 fmsl; and
(ii) The freeboard limit for Cell 3 is determined annually using a formula set out in
the procedure. The current freeboard limit for Cell 3 was calculated under this
procedure at 5,601.6 fmsl.
In addition, Part I.D.2 of the Permit provides that under no circumstances shall the
freeboard of any tailings cell be less than three feet, as measured from the top of the
flexible membrane liner ("FML"). The top of the FML in Cell 1 is at 5,618.5 fmsl and
the top of the FML in Cell 3 is at 5,608.5 fmsl. This means that the maximum
wastewater pool elevations in Cells 1 and 3 permitted under Part 1.D.2 of the Permit are
5,615.5 and 5,605.5 fmsl, respectively.
As indicated in the table below, the waste water pool elevations in Cells 1 and 3, as
measured during the Quarter, did not exceed these regulatory standards:

c. Weekly Slimes Drain Water Level Monitoring
Upon approval of the DMT Monitoring Plan required by Part I.H.13 of the Permit, Mill
personnel will monitor and record weekly the depth to wastewater in the slimes drain
access pipe at Tailings Cell2 to determine maximum and minimum fluid head before and
after a pumping cycle, respectively. These measurements were not taken during the
Quarter, but will be taken upon approval of the DMT Monitoring Plan, which is currently
under review by the Executive Secretary. Part I.E.6.b) of the Permit provides that this
requirement shall apply to Cell 3 only upon initiation of tailings de-watering operations.
As Tailings Cell 3 is currently an active tailings cell and de-watering operations have not
commenced, no such measurements will be made in the slimes drain access pipe for Cell
3 in the foreseeable future.
d. Weekly Wastewater Level Monitoring: Roberts Pond
Mill personnel monitored and recorded weekly, commencing on March 8, 2005, the
effective date of the Permit, the wastewater levels at Roberts Pond to determine
compliance with the DMT operations standards in Part I.D.3. of the Permit. Part I.D.3 of
the Permit provides that the water level in Robert's Pond shall not exceed an elevation of
5,624 fmsl. The results of such monitoring, reported as feet above mean sea level (fmsl),
are included in Tab J.
The maximum wastewater elevation measured in Robert's Pond during the quarter of
5,619.04 fmsl did not exceed the maximum permitted elevation of 5,624.0 fmsl.
e. Weekly Feedstock Storage Area Inspection
Weekly feedstock storage area inspections were performed by the Radiation Safety
Department, commencing on March 8, 2005, the effective date of the Permit, to confirm
that the bulk feedstock materials are stored and maintained within the defined area
described in the Permit and that all alternate feedstock located outside the defined
feedstock area are maintained within water tight containers. The results of these
inspections are recorded on the Weekly Mill Inspection Forms, which are available at the
Mill for inspection. No variance in stored materials from this requirement or leaking
altemate feedstock drums or other altemate feedstock containers were observed during
the inspections.
