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 the 4ft quarter of 2008 (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) and TW4-20 for the Quarter. 2. SAMPLING AI\D MONITORING PLAI\ 2.1. Description of Monitor Wells Sampled During the Quarter During the Quarter, the following chloroform contaminant investigation groundwater samples and measurements were taken: 2.1.1. Grogndwatgr Moqitorins Groundwater Monitoring was performed in all of the chloroform monitoring wells, being the following wells: o MW4r TW4-1t TW4-2o TW4-3r TW4-4 e TW4-5o TW4-6e TW4-7r TW4-8r TW4-9. TW4-10 r TW4-11. TW4-12. TW4-13r TW4-14r TW4-15 (Nrw-26)o TW4-16r TW4-17 (Mw-32) o TW4-18r TW4-19r TW4-20r TW4-21e 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: r Chloroform o Chloromethanec Carbon tetrachloride e Methylene chloride r Chloride e Nitrogen, Nitrate + Nitrite as N I t I I I I I I I I I I I I I I I I I 2.1.2. GroundwaJpr Hqad 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 2.1.1 Groundwater In addition, weekly depth to groundwater measurements were taken in MW-4, TW4-15 (MW-26), TW4-19 and TW4-20, as part of the long term pumping test for MW-4. 2.2, Sampling Methodology, Equipment and Decontamination Procedures The sampling methodology, equipment and decontamination procedures that were performed foi tfue chloroform contaminant investigation during the Quarter can be summarized as follows: 2.2.1. Well Pureine 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-deteci wJlk-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 quarters 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 purglng 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 pu-p is removed from the well and the process is repeated at each well location *orirrg from least contaminated to most contaminated. All wells are capped and secured prior to leaving the sampling location. 2.2.2. Safnpling a) 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 above on October 14,2008; b) The point of compliance monitoring wells under the Mill's Discharge Permit (*GWDP") on November 3-13, 2008. c) Piezometers - P-1, P'2,P'3,P-4, and P-5 on November 25,2008' (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 locaiion.- 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. b) Mill personnel use a disposable bailer to sample each well. The bailer is attached to a riel of approximately 150 feet of nylon rope and then lowered into the well. After cominglnto 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 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 NihatesA.litrites. This sample is also not filtered and is preserved with H2SO4 (the bottle for this set is also provided by the Analytical Laboratory); (iiD 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 corespondence to UDEQ dated December 8, 2006. Subsequent to the delivery of the Decernber 8, 2006 letter, DUSA discussed the issues brought forward in the letter with UDEQ and has received correspondence from UDEQ about those issues. In 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 progftIm, and is and attachment to the GWDP QAP where QA needs other than those described in the chloroform QA document are addressed. 2.3 Field Data Worksheets Attached under Tab B are copies of all Field Data worksheets that were completed during the euarter for the chloroform contaminant investigation monitoring wells listed in paragraptr2.l.l above and sampled October 15, 2008' 2.4 Depth to Groundwater Sheets Attached under Tab C are copies of the Depth to Water Sheets for the weekly monitoring of MW-4, TW4-15 (MW-26), TW4-19 and TW4-20 as well as the monthly depth to groundwater monitoring data for chloroform contaminant investigation wells measured during the quarter. bepth-to-groundwater measurements which were utilized for groun-<lwater contours are included on the Field Data Worksheets at Tab B of this report' 3. DATA INTERPRETATION 3.1. Interpretation of Groundwater Levels, Gradients and Flow Directions' 3.1.1. Current Site,Grou4Swater Contour Map The contour map uses the October 14, 2008 data for the wells listed in paragraph 2'l'2 (a) above, Novernber 3-13, 2008 data for the wells listed in paragraph 2.1.2 (b), and November 25,,2008 for the piezometers and wells listed in paragraph 2'l'2 (c) above' Also included under Tab D is a groundwater contour map of the portion of the Mill site where the four chloroform purnping wells are located, with hand-drawn stream tubes, in order to dernonstrate hydraulic capture from the pumping 3.1.2 Maps f,or Previous O\rarter The groundwater contour maps for the Mill site for the third quarter of 2008, as.submitted with the Chloroform Monitoring Report for the third quarter of 2008, are attached under Tab E. A comparison of the water table contour maps for the Quarter to the water table contour maps fir the previous quarter indicates similar patterns of drawdown related to pumping of MW-+, MW-ZO 1fW+-tS;, TW4-19 ana iW+-ZO. Water levels and water level contours for the site have not changed significantly since the last quarter, except for a few locations. Reported increases in water levels of approximately 5 feet in MW-19 and of approximat ely 17 feet in pumping well TW4-19 occurred. The increase at MW-19 yields a water level more typical of historical measurements at this well. 4 Water level fluctuations at pumping wells MW-4, MW-26 (TW4-15), TW4-19, and TW4-20 are due in part to fluctuationr in pumping conditions just prior to_and at the time the measurements are taken. The largesi increase (decrease in drawdown), of approximately 17 feet, occurred at TW4-19' 3.1.3 Hydroeraohs Attached under Tab F are hydrographs showing groundwater elevation in each chloroform contaminant investigation monitor well over time. 3.r.4 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 Hydr,aulic Capture perched water containing chloroform has been removed from the subsurface by pumping Mw-4, Tw4-19, Mw-2; (Tw4-15), and TW4-20. 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 l) they are located in areas of the perched zone having relatively high ;#.uU1tty and saturated thickness, and 2) high concentrations of chloroform *"r. d"t""ted 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 'trigh proauctivity. The combination of relatively high productivity and high chloroform concentrations allows a high rate of chloroform mass rernoval. The impact of pumping these wells is indicated by the water level contour maps attached under Tabs D i"a n. don"r of depression have developed in the vicinity of the pumping wells which continue to rernove iignificant 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 3.1.2, an increase in water level (decrease in drawdown) occurred at TW4-19 between the third and fourth quarters of 2008. Overall, the combined capture of TW4-19, TW4-20, MW4 and MW-26 (TW4-15) has not changed significantly since the last quarter. The large decrease in drawdown at TW4-19 has decreased the apparent capture zone of this well relative to that of other nearby pumping wells. Although high chloroform concentrations exist at some locations downgradient of the pumping *.llr 1fo. 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. Bypumping at the more productive, upgradient locations, however, the rate of Oo*ngraaiint ttrtoroform migration will be diminished because of the reduction in hydraulic gradients, and natural attenuation will be more effective a) b) I T I I I I I I I I I I I I I I I I I 3.2. Interpretation of Analytical Results 3.2.1.

Electronic Data Files arld Format DUSA has provided to the Executive Secretary an electronic copy of all laboratory results for groundwater quality monitoring conducted Y9:t the chloroform contaminant investigation during the Quarter, in Conima Separated Values (CSV)' A copy of the transmittal e-mail is included under Tab I' 3.2.3 Included under Tab J of this Report is a current chloroform isoconcentration map for the Mill site. Attached under Tab K is a table summarizing chloroform and nitrate values for each well over time. Attached under Tab L are graphs showing chlorolorm concentration trends in each monitor well over time. As TW4-14 *u, p.&iously dry and wells TW4'23,4-24 and 4- 25 have limited aii, u trend graph for that weli has not been included but will be included with the ;if'a;;tipott as sufficient data will have been collected at that time. 3.2.5 Analvsis of Analytical Rgslrlts Comparing the analytical results to those of the previous quarter, as summarized in the table incli<1ed undeiTab K, the following observations can be made: Chloroform concentrations have increased by more than-1}% in the following *.ttt, compared to last quarter: TW4-10, TW4-15, and TW4-21' Chloroform concentrations have decreased by more than 20Vo in the following wells, compared to last quarter: TW4-16 andTW4-22; within 20% it the following wells TW4-2, TW4-4, TW4-5, TW4-6,c) Chloroform concentrations have remained compared to last quarter: MW-4, TW4-1, TW4-7, TW4-11, TW4-18, and TW4-19; I I t I I I I I I I I I I I I I I I t d) chloroform concentrations at TW4-24 decreased from 2.9 pglL to non detect; and e) TW4-3, TW4-8, TW4-9, TW4-12, TW4-13, TW4-14, MW-32 (TW4-17), TW4- 23, and TW4-25 rernained non-detect' In addition, between the third and fourth quarters of 2008, the chloroform concentration in well TW4-Z:, increased from 120 pgi- to 170 pgtL, and the concentration in well Tw4-zzdecreased from 6,300 p{L to An pgt. wslls Tw4-23 and TW4-25 rernained non-detect for chlorofo.-, *a lhe concentration in well TW4-24 decreased from 2'9 p"glL to non detect. Tw4:24,located west of TW4-22, and TW4-25, located north of fll+-Zt,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 ternporary well TW4-23, decreased from 39 to 37 ugt.This wejl has likely remained outside the chloroform plume due to a combination of l) slow rates of downgradient chloroform migration in this area due to low permeability conditions and Ihe effects of upgradient chloroform removal by pumping, and 2)natural attenuation. Both TW4-6 ana tW+-23 bound the chloroform plume to the south. 3.3. Quality Assurance Evaluation And Data validation euality assurance evaluation and data validation procedures in effect at the time of J-pfirg were followed. These involve three basic types of evaluations: field QC checks; -Analytical Laboratory checks; and checks performed by DUSA personnel' as described below. 3.3.

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 Managei concluded that such procedures had been followed, however, well TW4-20 was errantly not sampled for organic analytes. More specifically, a set of samples, including well TW4-20 was sampled in October but did not meet the ternperature specification for VOC sample receipt and required re-sampling. Due to an inadvertent error the sampling personnel missed re-collection of well TW4-20 for VOC's when the re-sampling of these wells occurred. b) Results From Field QC Checla The duplicate samples of TW4-17 indicated a relative percent difference within the prescribed standard of 20% for those parameters duplicated. However, chloioform presence was indicated in the field blank and rinsate samples. The matter of continued chloroform presence in these field blank and rinsate samples remain under investigation on the part of the QA Manager. During the 3'd Quater report period it was noted that field blank de-ionized water continued to yield trace volatile organic presence (i.e. Chloroform). This matter was further investigated by the QA manager and corrective measures included: 1) a confirmation that purchased de-ionized water had in fact been used for the field blank and, 2) two sets of 3 purchased de-ionized waters samples were prepared and duplicate sets were sent to each of two contract laboratories (Energy Lab and AWAa). Both Labs continued to report the presence of low concentration Chloroform in all of the purchased water samples (e.g. approximately 30 ppb)t Concurrently, these low concentrations of Chloroforn were found in the 4"' Quarter field blanks as well. During the QA review for the preparation of this report it was discovered that in fact what was purchased is the resin used to treat the water, and not the water itself. Accordingly, for the l't Quarter, 2009 samples of pretreated water, treated water and the field blanks thernselves will be analyzedto further isolate the cause of this low level contaminant source. c) Review of Analytical Laboratory QA/QC Analysis and Analytical Reports The QA Manager reviewed the Analytical Laboratory's QA/QC Summary Reports and made the following conclusions; I T I I I I I I I I I I I I I I I t I (i) Check samples were analyzed for each method used in analyzing the Chloroform investigation samples. These methods were: Parameterffi Method (ii) Nitrogen, (Nitrate + Nifite as N) 8353.2 Chloroform, E,624 Carbon tetrachloride 8624Chloromethane E'624 Methylene chloride 8624 Chloride A4500-CL B The check samples included at least the following: a method blank, a laboratory control spike (sample), a matrix spike and a matrix spike duplicate; (iii) All qualifiers, if any, and the corresponding explanations in the sunmary 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. (iv) The laboratory holding time for all analyses was within chloroform specification and sample temperature was acceptable upon receipt. 4. LONG TERM PUMP TEST AT MW-4, TW4-15 (MW-26), TW4-19 AND TW4-20, 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 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 MW4 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 9 I I I I I T I I I I I I I I I I I I I monitoring data for MW-4. 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 report, dated November 12, 2001, and in the May 26,2004 Final Report on the Long Term Pumping Test. Data collected during the Quarter included the following: a) Measurernent 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) operationalandnon-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. 4.3. 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 Decernber monthly Depth to Water monitoring sheets for all of the chloroform contaminant investigation wells are typically included under Tab C but will be transmitted separately on December 1, 2008. Monthly depth to water measurements for Septernber are recorded in the Field Data Worksheets included under Tab B. 4.4. Pumping Rates and Volumes 4.4.r. M,W-4 Approximately 91,320 gallons of water were pumped from MW4 during the Quarter. The average pumping rate from MW-4, when the pump was pumping, wtls 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 10 I T I I T I I I I I I I I I I I I I I then shuts offto allow the well to recharge. Water from MW4 was transferred to the Cell I evaporation pond through a pipeline installed specifically for that purpose. At the end of the 3rd Quarter,2008, and since commencement of pumping on April 14, ZOO3, an estimated total of approximately 1,817,460 gallons of water have been purged from MW-4.TW4'19 4.4.2 TW4-1s (MW-26) Approximately 589,620 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 I evaporation pond through a pipeline installed specifically for that purpose. At the end of the I't Quarter, ZiO7, and since commencement of pumping on April 30, 2003, an estimated total of approximately 9,223,150 gallons of water have been purged from TW4-19. 4.4.3 TW4-ls (MW-26) Approximately 55,700 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 purglng continuously, Uut 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. At the end of the I't Quarter, 2006, and since commencement of pumping on August 8, 2003, an estimated total of approximately 1,273,940 gallons of water have been purged from TW4-15. 4.4.4 TW4-20 Approximately 50,230 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 purglng 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 985,650 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, (Jtah,Revision 1.0 to UDEQ for approval. Upon approval of that plan, the Mill will coflrmence documenting its daily inspections of the ll operational status of the chloroform pumping wel! ol the daily inspection form, an "..*pf" of the form of which is aftachedas Tab M. Operational Problems No operational problems in the pumping wells were reported during the 3'd Quarter' 2008 period. 4.7 Conditions That May Affect water Levels in Piezometers No significant amount of water was added to any of the three wildlife diversion ponds during the Quarter. 4.8 ChloroformAnalYsis Monthly chloroform sampling ceased on November 8, 2003' From that time all chloroform contaminant inveJigation wells were sampled on a quarterly basis' The sample results are discussed above in Section 3'2' 5. CONCLUSIONS AND RECOMMENDATIONS The water level containing high occurring. contour map for the Quarter indicates that effective capture of water chloroform concentrat]ons in the vicinity of the pumping wells is Between the third and fourth quarters of 2008, the chloroform concentration in well Tw4-z:increased from 120 p/L to 170 pglL, and the concentration in well TW4-22 decreased from 6,t00 pglLto'oio pgr. Fluctuations in concentrations in these wells are likely related to variaiiJns in pumping in TW4-20 and nearby wells' and their location near the suspected former office tlactr fietd source area. Regardless of these measured fluctuations in chloroform concentrations, sampling of temporary we]ls- TW4'24 (located west of Tw4-22) and TW4-25 (located north ir rw+-zt), indicated these wells remain outside the chloroform plume and thus bound the plume to the west and north' Chloroform was not detected at either TW4-24 or TW4-25' Althouglr there was a general increase in chloroform concentrations inTW4-22 between the fourth quarter otZiOl and the third quarter of2008, t\e reported relatively-substantial increase between the second and third qrun"rr of 2008 (from l,2oo ltglL to 6,300 ttdL) seemed anomalous. The 630 pgll reported at TW4-22 for the fourth quarter of 2008 is within the pre-third quarter tu.rgl of concentrations measured at this well' continued pumping of Tw4-19, TW4-20, Mw-4, and Mw-26 (TW4-15) is recommended. puilping these wells, regardless of any short term fluctuations in concentrations detecti uI th" wells (such as at TW4-20), helps to reduce downgradient chloroform migration by rernoving chloroforn mass and reducing average hydraulic gradients, thereby allowing natural attenuation to be more effective' t2 I I I I I T I T I I t I I I I I t I I The chloroform concentration at downgradient well TW4-6 decreased from 39 to li pdl,. Although fluctuations in concentrations have occurred, this well has likely remained outside the chloroform plume due to a combination of l) slow rates of downgradient chloroform migration in this area due to low permeability conditions and the efrects of upgradient chl,oroform removal by pumpin8, and 2) natural attenuation' Chloroform remained non detect at downgradient temporary well TW4-23.

SAMPLE TEMPEMTURE COMPLIANCE: 4"C (r2.C) Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are handdelivered immediately after collection shall be considered acceptable if there isevidence that the chilling process has begun. GROSS ALPHAANALYSIS Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided bythis method for non potable waters should be viewed as inconsistent. RADON IN AIR ANALYSIS The desired exposure time is.48 hours (2 days). The time delay in retuming the canister to the laboratory for processingshould.be as short as possible to avoid excessive decay. Maximum recommended delay between end ofexp6sure tobeginning of counting should not exceed 8 days. SOIUSOLIO SAMPLES All samples reported on an as received basis unless othenrise indicated. ATRAZINE, SIMAZINEAND PCB ANALYSIS USING EPA 505 Data for Atrazine and simazine are reported from EPA 525.2, not from EPA 505. Data reported by ELI using EpA method505 reflects the results for seven individual Aroclors. When the results for all seven are I.iD (not dLtected), ilre samplemeets EPA compliance criteria for PCB monitoring.
