1. INTRODUCTION
This is the Quarterly Chloroform Monitoring Report, as required under State of Utah
Notice of Violation and Groundwater Corrective Action Order UDEQ Docket No. UGe-20-01 for the 2nd quarter of 2005 (the "Quarter") for International Uranium (USA)
corporation's ("IUSA's") white Mesa Uranium Mill (the "Mill,,). This Report alsoincludes the operations Report for the Long Term pump Test at MW-4, TW4-19 and
TW4-15 (MW-26) for the Quarter.
2. SAMPLING AND MONITORING PLAN
2.1. Description of Monitor Wells Sampled During the euarter
During the Quarter, the following chloroform contaminant investigation groundwater
samples and measurements were taken:
2.1.1. Groundwater Monitorins
Groundwater Monitoring was performed in all of the chloroform monitoring wells, being
the following wells:
o MW-4
o TW4-A
o TW4-1o TW4-2o TW4-3c TW4-4
o TW4-5
o TW4-6
o TW4-lo TW4-8o TW4-9o TW4-10
o TW4-11o TW4-12o TW4-13o TW4-14o TW4-15 (Mw-26)o TW4-16o lW4-11o TW4-18o TW4-19o TW4-20o TW4-21o TW4-22
The locations of these wells are indicated on the map attached under Tab A. All samples,
other than from TW4-19, were taken on May 24,2005. Tw4-19 was sampled on June 7,
2005, because the TW4- 19 pump was down on May 24, 2005.
Each of these wells was sampled for the following constituents:
o Chloroform
. The following major ions:o Nitrogen, Nitrate + Nitrite as N

In a letter dated March 9, 2005, the Utah Department of Environmental Quality("UDEQ") requested that IUSA add dichloromethane, chloromethane, chloride and
carbon tetrachloride to the list of quarterly monitoring parameters in all future chloroform
contaminant investigation groundwater sampling and analysis. At the time of sampling,
however, this matter was still under discussion with UDEQ. As a result, sampling during
the Quarter did not include these additional parameters.
2.1.2. Groundwater Head Monitoring
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 2.1.1
above on April 26,2005,May 24,2005 and June 30, 2005;b) All of the point of compliance monitoring wells under the Mill's Groundwater
Discharge Permit ("GWDP") on June 21,2005;c) Piezometers - P-l, P-2,P-3, P-4 and P-5 on June 21,2005; andd) Existing monitoring wells - MW-20 and MW-22 on June 24,2005.
In addition, weekly depth to groundwater was taken in Mw-4, Tw4-15 (MW-26) and
TW4-19. as part of the long term pumping test for MW-4, as discussed in Section 4
below.
2.2. SamplingMethodology,EquipmentandDecontaminationprocedures
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 Pursing 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
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 we11. well depth
measurements are taken and the two casing volumes are calculated
(measurements are made using the same instrument used for the monitoring we1ls
under the Mill's GWDP). The Grundfos pump (a 6 gpm pump) is then lowered
to the bottom of the well. Purging then begins. 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 placed in DI water and rinsed prior to leaving the well area. After the
t
I
I

I
nnsing is completed, the well is capped, and Mill personnel then move to the
next well for purging.
2.2.2. Sampling
a) Following the purging of all chloroform investigation wells, the sampling takesplace (usually the next moming). 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 Analyical Laboratory). OnceMill Personnel arrive at the well sites, labels are filled out for the various samples
to be collected. A1l personnel involved with the collection of water and samples
are then outfitted with rubber gloves;
b) 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;
(i) First, a set of VOC vials is filled. This set consists of three 40 ml vialsprovided by the Analytical Laboratory. The set is not filtered and is
preserued with HCL;(ii) Second, a 500 ml sample is collected for NitratesNitrites. This sample is
also not filtered and is preserved with H2SO4 (the bottle for this set is
also provided by the Analytical Laboratory); and
c) After the samples have been collected for a parlicular well, the bailer is disposedof 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.
This manner of sampling has been employed by Mill personnel for chloroform
contaminant investigation sampling, including for split sampling undertaken with UDEe
personnel, since the inception of the chloroform contaminant investigation.
IUSA is currently in the process of completing a standard operating procedure ("SOp,,)for sampling under the chloroform contaminant investigation, for review by UOEq, thatwill set out the forgoing procedures in more detail. IUSA is awaiting finaiization of tn"
groundwater sampling SOP and Quality Assurance Plan under the Mill's GWDP, before
submitting a draft SOP for chloroform contaminant investigation sampling to UDEe.
2.3. Field Data Worksheets
Attached under Tab B are copies of all Field Data Worksheets that were completed
during the Quarter for the chloroform contaminant investigation monitoring wells listedin paragraph 2.1.1 above, as well as for a fielcl blank (TW4-60) and a duplicate sample of
TW4-1 I (TW4-63). The Field Data Worksheets for the Quarter clo not include atl tf the

the revised draft GWDP soP and QAP by UDEe, IUSA will develop u, sop fot
chloroform contaminant investigation sampling, that will include many of the provisionsin the GWDP SOP, including a revised form of Field Data Worksheet, whiih will be
employed by Mill personnel following approval by UDEe.
2.4. Depth to Groundwater Sheets
Attached under Tab C are copies of the Depth to Water Sheets for the weekly monitonng
of MW4, TW4-15 and TW4-19 as well as the monthly depth to groundwater monitoring
for all of the chloroform contaminant investigation wells. Monthly depth to groundwater
measurements for the month of May are included on the Field Data Worksheets included
under Tab B.
3. DATA INTERPRETATION
3.1. Interpretation of Groundwater Levels, Gradients and Flow Directions.
3.1 .1. 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 Quarler, 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 Quarler's sampling event. The contour map uses the
June 30, 2005 data for the wells listed in paragraph 2.1.2 (a) above, the June 21 ,2a05data for the wells and piezometers listed in paragraph2.l.2 (b) and (c) and the June 24,2005 for the wells listed in paragraph 2.1.2 (d) above. Field Data Worksheets for the
June 2l and June 24 sampling and depth to groundwater measurements will be includedin the 2nd Quarter Groundwater and DMT Perfornance Monitoring Report that is
required under the GWDP to be filed with UDEe.
3.1.2.Current Groundw our Man to Grou Contour Ma
for Previous Quarter
The groundwater contour map for the Mill site for the first quarter of 2005, as submittedwith the Groundwater and DMT Performance Standard Monitoring Reporl for the l't
quarter of2005, dated June 30, 2005, is attached under Tab E.
A comparison of the water table contour map for the Quarler to the water table contour
map for the previous quarter indicates an expanded cone of clepression and capture zone
around TW4-15 (MW-26). Water level contours for the rest of the site have not changed
significantly.

3.1.3. Hlrdrosraphs
Attached under Tab F are hydrographs showing groundwater elevation in each
chloroform contaminant investigation monitor well over time. As TW4-20, TW4-21 and
TW4-22 were just recently installed and were first sampled this Quarter, hydrographs for
those wells have not been included this Quarter. Hydrographs for those wells will be
prepared and included in subsequent quarterly report.
3.1.4. 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, other
than for new wells TW4-20,TW4-21 andTW4-22.
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, and MW-26 (formerly TW4-15). The purpose of the pumping is to
reduce total chloroform mass in the perched zone as rapidly as is practical. These we1ls
were chosen for pumping because I ) 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 three
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.
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.

for the Quarter, along with the laboratory analllrical results for the field blank (TW4-60)
and the duplicate sample for TW4-11 (TW4-63). It should be noted that analy,tical results
for TW4-19 are reported separately, due to the fact that TW4-19 was sampled atalater
date than the other wells.
3.2.2. Electronic Data Files and Format
IUSA has provided to the Executive Secretary an electronic copy of a1l laboratory resultsfor groundwater quality monitoring conducted under the chloroform contaminant
investigation during the Quarter, in Comma Separated Values (CSV). Copies of the
transmittal e-mails are included under Tab i.
3.2.3. Current Chloroform Isoconcentration Map
Included under Tab J of this Report is a current chloroform isoconcentration map for theMill site.
3.2.4. Data and Graphs Showinq Chloroform Concentration Trends
Attached under Tab K is a table summarizing chloroform and nitrate values for each well
over time. TW4-14 continues to be dry.
Attached under Tab L are graphs showing chloroform concentration trends in each
monitor well over time. As TW4-20, TW4-21 and TW4-22 wercjust recently installed
and were first sampled this Quarter, graphs showing chloroform concentration trends for
those wells have not been included this Quarter. Such graphs for those wells will be
prepared and included in subsequent quarterly reports. In addition, as well TW4-14
continues to be dry, a trend graph for that rvell has not been included.
3.2.5. Analysis of Anallrtical Results
On a review of the analytical results, compared to the results from previous periods, as
summarized in the table included under Tab K, the following observations can be made:
a) Chloroform concentrations have increased in the following wells, compared to
last quarter: MW-4, TW4-1, TW4-15;
b) Chloroform concentrations have decreased in the following wells, compared to
last quarter: TW4-4, TW4-5, TW4-7, TW4-8, TW4-9, TW4-10, TW4-ll, TW4-
16, TW4-18, TW4-19;and
c) Chloroform concentrations have remained more or less the same in the following
wells compared to last quarter: TW4-A, TW4-2, TW4-3, TW4-6, TW4-L2,TW4-
13, TW4-17.
I
I
T
I
T
I
In addition, new chloroform contamination investigation wells TW4-20, TW4-21 andTW4'22 were sampled for the first time during the Quarter. TW4-14 continues to be dry.
These data indicate that overall the pumping of water from three of the wells is reducing
the chloroform concentration in the majority of the wells and is hopefully slowing thedowngradient movement of the contaminated water.
One of the recently completed investigation wells, TW4-20, had chloroform levels of39,000 ug/L, almost an order of magnitude higher than any other well. The highconcentration is not surprising considering that TW4-20 is directly downgradient of theformer office leach field which is known to have accepted chloroform-laden laboratorywaste. The concentrations of 340 uglL detectecl at TW4 -22, located, cross-gradient ofTW4-20, and 192 ug/L detected at TW4-21, located upgradient of TW4-2b (and theformer office leach field), are more than two orders of mignitude lower than at iWq-ZO.Detectable concentrations at these cross- and upgradient locations may have resultedfrom lateral spreading of leach field solutions as they percolated down to the perched
water zone.
Because TW4-20 is located in a zone of relatively high perched zone permeability,
pumping of this well would significantly increase the current rate of chloroform mass
removal from the perched zone. IUSA recommends that TW4-20 be added to the currentpumping network.
3.3. Quality Assurance Evaluation And Data Validation
Quality assurance evaluation and data validation procedures in effect at the time ofsampling were followed. These involve three basic types of evaluations: field eCchecks; Analytical Laboratory checks; and checks periormed by Mill personnel, asdescribed below.
3.3.1. Field OC Checks
The following QC samples were generated by Mill personnel and submitted to theAnalytical Laboratory, in order to assess the quality of data resulting from the fieldsampling program:
a) One field blank (TW4-60); andb) One duplicate sample of TW4-11 (TW4-63).
These samples were sent blind to the Analytical Laboratory for analysis for the same
parameters as the other field samples.
In addition, a trip blank was prepared and sent to the Analytical Laboratory. However,
because the trip blank was not accompanied by a chain of custody For*, it wasmisplaced at the Analy'tical Laboratory. Mill personnel will ensure that future trip blanks
are accompanied by a properly completed Chain of Custody form.

3.3.2. Anal)rtical Laboratoryr QA/OC Procedures
The Analyical Laboratory has provided a summary report of the analltical quality
assurance/quality control (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 fotms, are included under Tab M (because the sample from TW4-19 was
submitted to the Analytical Laboratory subsequent to the samples from the other wells,
there is a separate Analyical Laboratory QA/QC Summary Report for TW4-19).
3.3.3. Mill OA Manaser Review
The Mill QA Manager, which is the Mill's Radiation Safety Officer, performed three
tlpes of reviews: a determination of whether Mill sampling personnel followed Mill
samplingprocedures; a review of the results from the Field QC Checks; and areview 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 sampling procedures summarized in
Section 2.2 above, the QA Manager concluded that such procedures had been followed,
with the following exception:
(, A Chain of Custody form did not accompany the trip blank that was
prepared in connection with the chloroform contaminant investigation
sampling for the Quarter, with the result that the trip blank was misplaced
by the Analy'tical Laboratory and no analyical results were reporled for
the trip blank. Mill personnel will ensure that a properly completed
Chain of Custody form accompanies each trip blank in the future.
b) Results From Field QC Checl<s
A review of the results of the duplicate sample, TW4-63 indicates agreement of each
analyte compared to the results for TW4-11 and that the contaminant concentrations are
sufficiently accurate.
A review of the results for the field blank indicates a measurement of 37.8 ug/L of
chloroform. This should have shown a non-detect result. The field blank was prepared
by Mill radiation staff in the Mill's laboratory and consists of de-ionized water. The fact
that the field blank resulted in the measurement of some chloroform suggests that some
chloroform contamination was introduced from the Mill's laboratory. Analyses of
similarly prepared field blanks for other recent sampling campaigns at the Mill also
indicate that some contaminants, for example chloroform and acetone, may have been
introduced into the sample while being prepared in the Mill's laboratory. Mill staff are

currently reviewing their piocedures for preparing such field blanks in order to minimize
the chances of this happening in the future.
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)
Parameter
Nitrogen, Nitrate + Nitrite as N
Chloroform
(iv)
Check samples were analyzed for each method used in analyzing the
groundwater samples. These methods were:
Method
E353.2
F'624
(ii) The check samples included at least the following: a method blank, a
laboratory control spike (except for method E353.2), a matrix spike and a
matrix spike duplicate. For method F,353.2, the Analy.tical Laboratory
runs a combination of Initial Calibration Verification (ICV) and
Continuing Calibration Verification (CCV) in lieu of a laboratory control
spike. The ICV and CCV results are not reported in the Analytical
Laboratory's QA/QC Summary Reports. However, the Analytical
Laboratory has verified to Mill staff that the ICV and CCV results were
within the norm for this method;
There were no qualifiers reported in the QAIQC Summary Reports for
any of the check samples for either of the analytical methods. All
qualifiers, if any, and the corresponding explanations in the summary
reports are reviewed by the QA Manager;
There were no qualifiers reported in the Laboratory Analytical Reports,
other than an indication that the Reporting Limit was increased due to
sample matrix interference in a number of cases. The sample matrix
interference was due to the dilution required in order to analyze for the
relatively high concentrations of chloroform. However, because the
amounts reported were well in excess of the increased reporting limit in
all samples, the fact that the reporling limit was increased in those cases
had no practical impact on the analysis; and
A review of the surrogate spiked samples for each sample also showed
that the Reporting Limit was increased due to sample matrix interferencein those samples where the Reporling Limit for chloroforn was
increased. In addition, in one sample, TW4-2, the oh recovery for the
surogate 1,2-Dichlorobenzene-d4 was outside of the advisory limits.

This matter was discussed with the Analytical Laboratory. The
Analltical Laboratory advised that the first surrogate was rendered
unacceptable as a result of the dilution required in order to analyze the
high concentration of chloroform. This is not an unusual result for
samples containing these levels of chloroform. However, as indicated on
the Laboratory Analytical Report, since the remaining three surrogate
samples were within the norm, the laboratory QA for the sample was
considered to be adequate and the batch was approved by the Analytical
Laboratory.
4. LONG TERTVT pUMp TEST AT MW-4, TW4-15 (MW-26) AND TW4-19,
OPERATIONS REPORT
4.1. Introduction
As a part of the investigation of chloroform contamination at the Mill site,IUSA has been
conducting a Long Term Pump Test on MW4, TW4-19, and TW4-15 (MW26). 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 MW4 was started on April 14,2003, followed by the start of
pumping from TW4-19 on April 30, 2003, and from TW4-15 on August 8, 2003.
Persomel 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 MW4. IUSA 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 repoft, dated November 12,
2001, and in the May 26,2004 Final Report on the Long Term Pumping Test.
Data collected during the Quarter includes the following:
Measurement of water levels at MW-4, TW4- 19 and TW4- 15 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);
Measurement of pumping history:

discussed in detail in Section 3.2 above.
4.3. Water Level Measurements
Beginning August 16, 2003, the frequency of water level measurements from MW4,
TW4-15, and TW4-19 was reduced to weekly. Depth to groundwater in all other
chloroform contaminant investigation wells is monitored monthly. Copies of the weekly
Depth to Water monitoring sheets for MW4, TW4-15 and TW4-19 and the April and
June monthly Depth to Water monitoring sheets for all of the chloroform contaminant
investigation wells are included under Tab C. Depth to groundwater measurements for
May are included in the Field Data Worksheets included under Tab B.
4.4. Pumping Rates and Volumes
4.4.r. MW4
Approximately 97,370 gallons of water were pumped from MW4 during the Quarter.
The average pumping rate from MW4, when the pump was pumping, was approximately
4.0 gpm throughout the Quarler. 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 MW4 was transferred to the Cell 1 evaporation pond through a
pipeline installed specifically for that purpose. Since commencement of pumping on
April 14, 2003, an estimated total of approximately 704,600 gallons of water have been
purged from MW4.
4.4.2. TW4-19
Approximately 296,580 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 5.0 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 I evaporation pond
through a pipeline installed specifically for that pu{pose. Since commencement of
pumping on April 30, 2A03, an estimated total of approximately 2,785,556 gallons of
water have been purged from TW4-19.
4.4.3. TW4-1s (MW-26)
Approximately 65,360 gallons of water were pumped from TW4-15 during the Quarter.
The average flow rate from TW4-15, when the pump rvas pumping, was approximately 3
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 I evaporation pond through a
pipeline installed specifically for that purpose. Since commencement of pumping on

4.5. Operational Problems
The following operational problems were encountered during the Quarler:
a) The pump was removed from TW4-15 on the 8'h of April in order to help
develop the well;
b) The flow meter was not operating on TW4-19 on the 8th of April. A new meter
was installed on the 20th of April;
c) The TW4-19 pump went down around the 20th of April. A new pump was
installed on the 25'n of April; and
d) A! obstruction in the tube on TW4-19 (a dead mouse) was encountered on June
3'd, where depth to water measurements are made. The obstruction was
somewhere around the 40 foot mark. This problem was rectified on June 29.
200s.
4.6. Conditions That May Affect Water Levels in Piezometers
No water was added to the wildlife diversion ponds during the Quarter.
4.7. ChloroformAnalysis
Monthly chloroform sampling ceased on November 8, 2003. From that time all
chloroform contaminant investigation wells were sampled on a quarterly basis. During
the Quarter, samples from MW4, TW4-19 and TW4-15 (MW-26) were taken from a
small valve and tee placed in the discharge line downstream from the pump control valve
for each well. The sample results are discussed above in Section 3.2.
5. CONCLUSIONS AND RECOMMBNDATIONS
The water level contour map for the Quafter, indicates that effective capture of water
containing high chloroform concentrations in the vicinity of the pumping wells is
occurring.
The analytical data from the Quarter indicate that overall the pumping of water fiom
three of the wells is reducing the chloroform concentration in the majority of the wells
and is hopefully slowing the downgradient movement of the contaminated r,vater.
With regard to TW4-20, the high chloroform concentration (39,000 ug/L) detected in the
initial sampling is not surprising considering the well is located immediately
downgradient of the former office leach field. The former office leach field is known to

have accepted chloroform-laden laboratory wastes more recently than the abandoned
scale house leach field (which is the most likely source for the chloroform detected at
MW-4). Concentrations of 340 ug/L detectedatTW4-22,locatedcross-gradient of TW4-
20 (and also on the edge of tailings Cell 2), and of lg2 lu'glL detected atTW4-2l,located
upgradient of TW4-20 (and the former office leach field), are more than 2 orders of
magnitude lower than at TW4-20. The detectable concentrations at these cross- and
upgradient locations are likely the result of lateral spreading of leach field solutions as
they percolated down to the perched zone.
TW4-20 is located in an area of the perched zone that has a relatively high transmissivity
due to relatively high permeability and saturated thickness. Because of the likely high
productivity of this well, and the high chloroform concentration at this location, pumping
of this well in addition to those curently pumped is recommended. Adding this well to
the pumping network is expected to result in significantly higher chloroform mass
removal rates. The additional reduction in hydraulic gradients that will result from
pumping TW4-20 will fuither reduce downgradient chloroform migration rates. The
reduction in downgradient chloroform migration rates combined with the increased rate
of chloroform mass removal will allow natural attenuation processes to be more effective.
