1. INTRODUCTION
This is the Quarterly Chloroform Monitoring Report, as required under State of Utah
Notice of Violation and Groundwater Corrective Action Order State of Utah Department
of Environmental Quality ("UDEQ") Docket No. UGQ-20-01 for the2"d Quarter of 2007
(the "Quarter") for Denison Mines (usA) corp.'s ("DUSA's") white Mesa uranium
Mill (the "Mill"). This Report also includes the Operations Report for the Long Term
Pump Test at MW-4, TW4-19, TW4-15 (MW-26) andTW4-20 for the Quarrer.
2. SAMPLING AND MONITORING PLAN
2.1.Description of Monitor Wells Sampled During the Quarter
During the Quarter, the following chloroform contaminant investigation groundwater
samples and measurements were taken:
2.I.1. Groundwater Monitoring
Groundwater Monitoring was performed in all of the chloroform monitoring wells, being
the following wells:
o MW-4o TW4-A
o TW4-1o TW4-2
o TW4-3
o TW4-4o TW4-5o TW4-6
o TW4-7o TW4-8o TW4-9
o TW4-10
o TW4-11o TW4-12o TW4-13o TW4-L4o TW4-15 (MW-26)o TW4-16o TW4-17 (MW-32)o TW4-18o TW4-19o TW4-20o TW4-21o TW4-22
The locations of these wells are indicated on the map attached under Tab A.
Wells sampled during this reporting period were analyzed,for the following constituents:
. Chloroformo Chloromethaneo Carbon tetrachlorideo Methylene chloride
o Chlorideo Nitrogen, Nitrate + Nitrite as N
As UDEQ is aware, Denison has experienced difficulty in obtaining chloroform samples
from well TW4-I4. The difficulty arises from the very limited recovery rate encountered
at that location. More specifically, it is generally necessary that there be at least 1.5 feetof water within the well in order to obtain a sample which is not influenced by
sedimentation from the bottom of the well. At the request of UDEQ, the recovery ratefrom the TW4-14 location was evaluated by bailing and routine water level
measurements in order to determine the necessary time between purging and sample
collection. Such an evaluation was undertaken between September 2l and October 20with limited success in water recovery experienced during this study period.
N"onetheless, quarterly samples were able to be collected from well TW4-14 during the
4'n Quarter of 2006 (November 8, 2006), this has continued in both the l't anJ 2nd
quarters of 2007. Because of the limited data base for MW-14, trend analyses is
premature and will await the collection of four quarters of data prior inclusion within the
graphic display at Tab L of this report. The chloroform concentration in this well was
less than the detection limit for the November 8,2006, February 28,2007 and 6l2tt07
samplings at that location.
2.I.2. Groundwater Head Monitorine
Depth to groundwater was taken in the following wells and/or piezometers during the
Quarter:
a) All of the chloroform contaminant investigation wells listed in paragraph Z.I.I
above on May 2,2007;b) The following point of compliance monitoring wells under the Mill's
Groundwater Discharge Permit ("GWDP") on 6-20-07 MW17, MW23, MIWZ4,
MW25, MW28 and MW32. It is noted that wells MW-l, MW-2, MW-3, MW-
3A, MW-5, MW-11, MW-12, MW-14, MW-15, MW_19, MW_19, MW_25
MW-27, MW-29, MW-30 and MW-31 were not measured per the request of
UDEQ to accommodate sampling conducted by the University of Utah study.c) Piezometers - P-1, P-2,P-3, P-4, and MW's 20 and zr on Jwre 29, zo07 . p-5 on
Jlune29,2007
ln addition, weekly depth to groundwater measurements were taken in MW-4, TW4-15
(Mw-26), Tw4-19 andrw4-20, as parr of the long term pumping test for Mw-4.
2,2. samplingMethodologyrEquipmentandDecontaminationprocedures
The sampling methodology, equipment and decontamination procedures that were
performed for the chloroform contaminant investigation during the Quarter can be
summarized as follows:
2.2.1. Well Purging and Depth to Groundwater
a) A list is gathered of the wells in order of increasing chloroform contamination.
The order for purging is thus established. Mill personnel start purging with all of

t
the non-detect wells and then move to the more contaminated wells in order of
chloroform contamination, starting with the wells having the lowest chloroform
contamination; and
b) Before leaving the Mill office, the pump and hose are rinsed with de-ionized
("DI") water. Mill personnel then proceed to the first well which is the well
indicating the lowest concentration of chloroform based on the previous quatrers
sampling results. Well depth measurements are taken and the two casing
volumes are calculated (measurements are made using the same instrument used
for the monitoring wells under the Mill's GWDP). The Grundfos pump (a 6 gpm
pump) is then lowered to the bottom of the well and purging is begun. At the
first well, the purge rate is established for the purging event by using a calibrated
5 gallon bucket. After the evacuation of the first well has been completed, the
pump is removed from the well and the process is repeated at each well location
moving from least contaminated to most contaminated. All wells are capped and
secured prior to leaving the sampling location.
2.2.2. Sampling
Following the purging of all chloroform investigation wells, the sampling takes
place (usually the next morning). Prior to leaving the Mill office to sample, a
cooler along with blue 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 the outfitted with rubber gloves. Chloroform investigation samples are
collected by means of dedicated bailers and the wells are purged by means of a
dedicated portable pump. Each quarterly pumping and sample collection event
begins at the location least affected by chloroform (based on the previous
quarters sampling event) and proceeds by affected concentration to the most
affected location. The dedicated portable pump is appropriately decontaminated
prior to each purging sampling event and the QA rinsate sample is collected after
said decontamination but prior to the commencement of the sampling event.
Mill personnel use a disposable bailer to sample each well. 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;
(D First, a set of VOC vials is filled. This set consists of three 40 ml vials
provided by the Analytical Laboratory. The set is not filtered and is
preserved with HCL;(ii) Second, a 500 ml sample is collected for Nitrates/lrlitrites. This sample is
also not filtered and is preserved with H2SO4 (the bottle for this set is
also provided by the Analytical Laboratory);

Third, a 500 ml sample is collected for Chloride. This sample is not
filtered and is not preserved; and
c) 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 blue ice. The well is
then recapped and Mill personnel proceed to the next well.
DUSA completed (and transmitted to UDEQ on May 25, 2006) a revised Quality
Assurance Plan ("QAP") for sampling under the Mill's GWDP. The GWDP QAP was
reviewed by UDEQ and has been approved for implementation. The QAP provides a
detailed presentation of procedures utilized for groundwater sampling activities under the
GWDP. While the water sampling conducted for chloroform investigation purposes has
been conformant with 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. [n response to
UDEQ's letter and subsequent discussions with UDEQ, DUSA has incorporated changes
in chloroform QA procedures in the form of a separate document. The chloroform QA
document describes the differing needs of the chloroform investigation program, and is
and attachment to the GWDP QAP where QA needs other than those described in the
chloroform QA document are addressed.

DATA INTERPRETATION
Interpretation of Groundwater Levels, Gradients and Flow Directions.
Current Site Groundwater Contour Map
Included under Tab D is a water table contour map, which provides the location of all of
the wells and piezometers listed in item 2.1.2 above for which depth to groundwater was
taken during the Quarter, the groundwater elevation at each such 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. The contour map uses the
May 2,2007 data for the wells listed in paragraph 2.1.2 (a) above, June 20, 2007 data for
the wells listed in paragraph 2.1.2 (b), and lune 29, 2007 for the piezometers and wells
listed in paragraph 2.1.2 (c) above.
Also included under Tab D is a groundwater contour map of the portion of the Mill site
where the four chloroform pumping wells are located, with hand-drawn stream tubes, in
order to demonstrate hydraulic capture from the pumping
3.1.2. Comparison of Current Groundwater Contour Maps to Groundwater Contour
Maps for Previous Ouarter
The groundwater contour maps for the Mill site for the first quarter of 2007, as submitted
with the Chloroform Monitoring Report for the first quarter of 2007, dated June 1, 2007,
are attached under Tab E.
A comparison of the water table contour maps for the Quarter to the water table contour
maps for the previous quarter indicates similar patterns of drawdown related to pumpingof MW-4, MW-26 (TW4-15), 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
decrease in water level of approximately 9 feet in MW-23, and an increase in water level
(decrease in drawdown) by approximately 8 feet at pumping well MW-26 (Tw4-15).
Water level fluctuations in the pumping wells are due in part to fluctuations in pumping
conditions just prior to and at the time the measurements are taken.
The water level decrease at MW-23 seems anomalous and may be due to the
measurement having been inadvertently taken shortly after a purging event. Water levels
in this well recover slowly after purging due to the low permeability of the perched zone
at this location.
3.1.3. Hydroeraphs
Attached under Tab F are hydrographs showing groundwater elevation in each
chloroform contaminant investigation monitor well over time.
3.I.4. Depth to Groundwater Measured and Groundwater Elevation
Attached under Tab G are tables showing depth to groundwater measured and
groundwater elevation over time for each of the wells listed in Section 2.1.1 above.
3.1.5. Evaluation of the Effectiveness of Hydraulic Capture
Perched water containing chloroform has been removed from the subsurface by pumping
Mw-4, Tw4-19, Mw-26 (formerly Tw4-15), and rw4-20. The purpose of the pumping
is to reduce total chloroform mass in the perched zone as rapidly as is practical. These
wells 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 the 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.
The impact of pumping these wells is indicated by the water level contour maps attached
under Tabs D and E. Cones of depression have developed in the vicinity of the pumping
wells 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 the pumping wells is occurring. As
noted in Section 3.l.2,little change in measured water levels occurred between the first
and second quarters of 2007, except for the decreased drawdown at MW-26 (TW4-15),
and decrease in water level at MW-23. Overall, the combined capture of TW4-19, TW4-
20, MW-4 and MW-26 (TW4-15) has not changed significantly since the last quarter.
Although high chloroform concentrations exist at some locations downgradient of the
pumping wells (for example, near TW4-4), the low permeability of the perched zone at
these locations would prevent significant rates of chloroform mass removal should these
wells be pumped. By pumping at the more productive, upgradient locations, however,
the rate of downgradient chloroform migration will be diminished because of the
reduction in hydraulic gradients, and natural attenuation will be more effective.
3.2. Interpretation of Analytical Results

3.2.4 Data and Graphs Showing Chloroform Concentration Trends
Attached under Tab K is a table summarizing chloroform and nitrate values for each well
over time. TW4-14 had a small amount of water just sufficient for sampling (see the
discussion in Section 2.1.1 above)
Attached under Tab L are graphs showing chloroform concentration trends in each
monitor well over time. As TW4-14 was previously dry, a trend graph for that well has
not been included.
3.2.5 Analysis of Analvtical Results
Comparing the analytical results to those of the previous quarter, as sufirmarized in the
table included under Tab K, the following observations can be made:
a) Chloroform concentrations have increased by more than 2OVo in the following
wells, compared to last quarter: TW4-7,TW4-21, andTW4-22.
b) Chloroform concentrations have decreased by more thart ZOVo in the following
wells, compared to last quarter: TW4-5, TW4-6, TW4-10, TW4-15, TW4-16
and TW4-20;
Chloroform concentrations have remained within 20Vo in the following wells
compared to last quarter: MW-4, TW-4-1, TW4-2,TW4-4, TW4-9, TW4-11,
and TW4-18;
Chloroform concentrations at Tw4-9 increased from non-detect to 2lltgtL; ard
e) Tw4-3, Tw4-12, Tw4-13, Tw4-14, and MW-32 (Tw4-r7) remained non-
detect.
In addition, between the first and second quarters of 2007, the chlorofofln concentration
in well TW4-20 decreased from 4,400 pgtL to 1,800 VglL, the concentration in TW4-21
increased from 160 pg/L to 300 prg/L, and the concentration in TW4-22 increased from
aa0 pglLto 740 VglL.Chloroform was not detected at new wells TW4-23 andTW4-25,
and was detected at a concentration of approximately 3StglL at new well TW4-24. TW4-24, located west of rw4-22, and rw4-25, located north of TW4-21, bound the
chloroform plume to the west and north.
Chloroform concentrations in TW4-6, which was the most downgradient temporary
perched well prior to installation of new temporary well TW4-23, decreased from 46 to11
ptg/L. This decrease in concentration after two quarters of increases is likely due to a
combination of 1) slow rates of downgradient chloroform migration in this area due tolow permeability conditions and the effects of upgradient chloroform removal by
pumping, and 2) natural attenuation. Both TW4-6 and TW4-23 bound the chloroform
plume to the south.

Quality Assurance Evaluation And Data Validation
Quality assurance evaluation and data validation procedures in effect at
sampling were followed. These involve three basic types of evaluations:
the time of
field QCchecks; Analytical Laboratory checks; and checks performed by DUSA
described below.
personnel, as
3.3.1 Field OC Checks
Field Quality Control samples for the chloroform investigation program consist of a field
duplicate sample, a field blank and a trip btank. These check samples are to be generated
for each quarterly sampling episode. During the 2"d Quarter of 2006 duplicates (TW4-65,
duplicate of TW4-20 and TW4-70, duplicate of TW4-15), a DI blank (Tw4-60) and a
trip blank were collected and analyzed. The results of these analyses are included with
the routine analyses under Tab H.
3.3.2 Analytical Laboratory OA/OC Procedures
The Analytical Laboratory has provided summary reports of the analytical quality
assurance/quality control (QA/QC) measurements necessary to maintain conformance
with NELAC certification and reporting protocol. The Analytical Laboratory eA/eCSummary Report, including copies of the Mill's Chain of Custody and Analytical
Request Record forms, for the November sampling event, are included under Tab H.
3.3.3 Mill OA Manager Review
The Mill QA Manager, which, for these sampling events was DUSA's Manager of
Environmental Affairs, performed four types of reviews: a determination of whether Mill
sampling personnel followed Mill sampling procedures; a review of the results from theField QC Checks; a review of analytical reports for holding times and qualifying
indicators for the data; and a review of the Analytical Laboratory QA/QC anatysis.
-ttre
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 sampling procedures summarized in
Section 2.2 above, the QA Manager concluded that such procedures had been followed.
b) Results From Field QC Checks
The duplicate samples of TW4-20 indicated a relative percent difference within the
prescribed standard of 20Vo, however the duplicate of MW-15 was out of specification at
a relative percent difference of -28.6 Vo. In addition, chloroform presence was indicated
in the field blank and rinsate samples.

In response to these conditions, the QA Manager has priviously investigated possible
causes of these Quality Assurance anomalies. The areas of inquiry have included
possible sources of chloroform from the DI distribution system and methods of sample
duplication. As a result of these discussions, the following actions were under
considered:
Eliminating the receipt of chlorinated water to the DI ion-exchange cylinder.
Providing carbon filtration as a polishing (final) step in the DI water generation
process.
Developing a VOC duplicate sampling plan which ensures the collection of a
single homogeneous sample into one corlmon container from which duplicate
splits are distributed for analytical purposes. The duplicate method is designed to
accomplish this same end result but may be improved upon. Any modification in
this procedure will be provided to UDEQ for review and concurrence.
After considerable discussion, a carbon filtration unit has been added to the DI water
generation process and the results of that improvement will be assessed for the 3'd quarter
sampling period, which occurred subsequent to the filtration unit installation.
c) Review of Analytical Laboratory Q,a/QC Analysis and Analytical Reports
The QA Manager reviewed the Analytical Laboratory's QA/QC Summary Reports and
made the following conclusions;
Check samples were analyzed for each method used in analyzing the
Chloroform investigation samples. These methods were:

The check samples included at least the following: a method blank, a
laboratory control spike (sample), a matrix spike and a matrix spike
duplicate;
All qualifiers, if any, and the corresponding explanations in the suflrmary
reports are reviewed by the QA Manager. The only qualifiers reported
were for matrix interference in some of the analyzed, monitoring location
samples, however, the reporting limit was maintained below the
parameter standard in these instances.

4. LONG TERM PUMP TEST AT MW-4, TW4-L5 (MW-26), TW4-19 AND
TW 4-20, OPERATIONS REPORT
4.1. Introduction
As a part of the investigation of chloroform contamination at the Mill site, ruSA has been
conducting a Long Term Pump Test on MW-4, TW4-19, TW4-15 (MW-26) and TW4-
20. 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.
4.2. 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 TW4-15 (MW-26) on August 8, 2003
and from TW4-20 on August 4,2005. 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. ruSA 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,
2OOl, and in the May 26,2004 Final Report on the Long Term Pumping Test.
Data collected during the Quarter included the following:
a) Measurement of water levels at MW-4, TW4-19, TW4-15 (MW-26), and TW4-
20 on a weekly basis, and at selected temporary wells and permanent monitoring
wells on a monthly basis (See Section 3.1 and Tabs B and C for a discussion of
the water levels);
b) Measurement of pumping history:
(i) pumping rates
(ii) total pumped volume
(iii) operational andnon-operationalperiods;
c) Periodic sampling of pumped water for chloroform and nitrate & nitrite analysis
and other constituents, as discussed in detail in Section 3.2 above.

Water Level Measurements
Beginning August 16, 2003, the frequency of water level measurements from MW-4,
TW4-15 (MW-26), and TW4-19 was reduced to weekly. From commencement of
pumping TW4-20, water levels in that well 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, TW4-15
(MW-26), TW4-19 and,TW4-20 and the October and December 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 November are recorded in the
Field Data Worksheets included under Tab B.
4.4. Pumping Rates and Volumes
4.4.1. MW4
Approximately 81,230 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
4.0 gpm throughout the Quarter. The well is not purging 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. At the end of the 1't Quarter, 2007, and
since commencement of pumping on April 14,2003, an estimated total of approximately
1,307,110 gallons of water have been purged from MW-4.
4.4.2. TW4-19
Approximately 605,400 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 6.0 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. At the end of the l't Quarter,
2007, and since commencement of pumping on April 30,2003, an estimated total of
approximately 6,768,986 gallons of water have been purged from TW4-19.
4.4.3. TW4-15 (MW-26)
Approximately 54,400 gallons of water were pumped from TW4-15 (MW-26) during the
Quarter. The average flow rate from TW4-15, when the pump was pumping, was
approximately 1.5 gpm throughout the Quarter. The well is not purging 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. At the end of the 1't

Quarter, 2006, and since coflrmencement of pumping on August 8, 2003, an estimated
total of approximately 930,510 gallons of water have been purged from TW4-15.
4.4.4. TW4-20
Approximately 163,520 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
6.0 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. Since commencement of pumping on August 4,2005, an
estimated total of approximately 642,290 gallons of water have been purged from TW4-
20.
4.5 Daily Inspections
Denison has submitted an Operations and Maintenance Plan, Chloroform Pumping
System, White Mesa Mill, Blanding, Utah, Revision 1.0 to UDEQ for approval. Upon
approval of that plan, the Mill will commence documenting its daily inspections of the
operational status of the chloroform pumping wells on the daily inspection form, an
example of the form of which is attached as Tab M.
4.6 Operational Problems
Operational problems for the 2"d Quarter of 2007 included the replacement of the TW4-
15 flow meter on May 29,2007 and the repair of several wells during May. More
specifically, starting on May 7,2007 the pumping wells MW4, TW4-15, TW4-19 and
TW4-20 were taken offline for repair. These wells were being retrofitted by Bayles
Exploration and were returned to service on May 29,2007.
4.7 Conditions That May Affect Water Levels in Piezometers
No water was added to any of the three wildlife diversion ponds during the Quarter.
4.8 Chloroform Analysis
Monthly chloroform sampling ceased on November 8, 2003. From that time all
chloroform contaminant investigation wells were sampled on a quarterly basis. The
sample results are discussed above in Section 3.2.
5. CONCLUSIONS AND RECOMMENDATIONS
The water level contour map for the Quarter indicates that effective capture of water
containing high chloroform concentrations in the vicinity of the pumping wells is
occurring.

Between the first and second quarters of 2007, the chloroform concentration in temporary
well TW4-20 decreased from 4,400 trtgtL to 1,800 ltgL, the concentration in TW4-21
increased from 160 ygtL to 300 pg/L, and the concentration in TW4-22 increased from
aaU pgtL to 740 yglL. Fluctuations in concentrations in these wells are likely related to
variations in pumping in TW4-20 and nearby wells, and their location near the suspected
former office leach field source area. Regardless of these measured fluctuations in
chloroform concentrations, sampling of new temporary wells TW4-24 (located west of
TW4-22) and TW4-25 (located north of TW4-21), indicated these wells are 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 approximately 3 pglL at
TW4-24.
continued pumping of TW4-19, Tw4-20, Mw-4, and MW-26 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.
The decrease in chloroform concentration at downgradient well TW4-6 from 46 toIl VglL after two quarters of increases is likely 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'chloroforrn removal by pumping, and 2) natural attenuation.
Chloroform was not detected at new downgradient temporary well TW4-23. Both TW4-6
and TW4-23 bound the chloroform plume to the south.
