July 31, 2017 Project IR12162612 Mr. Robert Romero Hazardous Substances Engineer California Department of Toxic Substances Control 5796 Corporate Avenue Cypress, CA 90630 Re: Report on Subsurface Water Sampling at the Former Aerojet Rocketdyne Chino Hills Facility, Chino Hills, California Dear Mr. Romero: Amec Foster Wheeler Environment & Infrastructure, Inc. (Amec Foster Wheeler) is assisting Aerojet Rocketdyne, Inc. (AR) in completing the RCRA Facility Investigation (RFI) and implementing Corrective Measures (CMs) at AR’s former Chino Hills facility (the site). This work is being conducted pursuant to the 1994 Consent Agreement between Aerojet and the California Department of Toxic Substances Control (DTSC). In response to public comments received as part of DTSC’s public review and comment process on the Phase 1 Corrective Measures Study (CMS) for Management Areas 1 and 2, DTSC requested in the letter dated December 1, 2016 that AR re-assess the water quality of subsurface water at the Upper A-12 Test Area and former Redwater Pond areas of the site. Pursuant to AR’s request, Amec Foster Wheeler developed and submitted a plan to DTSC titled Work Plan for Subsurface Water Sampling at the Former Aerojet Rocketdyne Chino Hills Facility (Work Plan) and dated March 23, 2017. The Work Plan included abandonment of monitoring well A12-MW3 because of roots encountered inside the well and installation of a nearby replacement well. DTSC approved the Work Plan by letter dated April 11, 2017. BACKGROUND The site is located in Chino Hills, California and is shown on Figure 1. In 1994, AR entered into a Consent Agreement with the DTSC to complete site investigation activities and implement CMs, as necessary and appropriate, at the site. In 1996 and 1997, the Upper A-12 Test Area was excavated to remove soils containing depleted uranium (DU). A grab subsurface water sample and duplicate sample were collected on November 16, 1998 and perchlorate was detected at concentrations up to 877 micrograms per liter (µg/L). Subsequently, soils in a limited area showing perchlorate impact were excavated from the former test area. On October 19, 1997, grab subsurface water samples were collected from the former Redwater Pond and explosive chemicals RDX and HMX were detected at concentrations up to 4,200 and 320 µg/L, respectively. In 2001, soils containing explosive chemicals (HMX and RDX) were removed from the former Redwater Pond area. Subsurface water monitoring wells have been installed at both areas, which are shown on Figure 2.

Pre and post-remediation subsurface water sampling and analysis has been conducted at these areas from 1997/1998 through 2007 under DTSC oversight in order to characterize the nature and extent of identified COCs. In 2008, DTSC notified AR that subsurface water monitoring could cease. The site is underlain by a non-water-bearing sedimentary rock formation. Thus, a continuous aquifer system is absent beneath the site and the site monitoring wells encounter localize occurrences of subsurface water. INVESTIGATION METHODS Pursuant to the Work Plan, the investigation methods and activities conducted as part of this subsurface water quality re-assessment included:  Permitting and Deviations from Work Scope;  Field Work Notification and Agency Oversight;  Monitoring Well A12-MW3 Destruction and Replacement;  Monitoring Well Development, Survey, and Sampling;  Analytical Testing; and  Quality Control Sampling Review. These activities are described below. Permitting and Deviations from Work Scope The subsurface water sampling and analysis was implemented in general accordance with the procedures and methodologies described in the Work Plan. Amec Foster Wheeler obtained permits from the San Bernardino County Public Health, Environmental Health Services (SBCPH) for the destruction of monitoring well A12-MW3 and construction of a new replacement well (A12-MW3R). Copies of the SBCPH well permits are included in Appendix A. Deviations from the proposed work scope included the following:  Field water quality parameters (dissolved oxygen, oxidation-reduction potential, pH, specific electrical conductance, temperature, and turbidity) could not be measured and recorded during development and sampling of replacement well A12-MW3R because of low recharge conditions;  Subsurface water samples were collected from all three Upper A-12 monitoring wells (A12-MW1, -2, and -3R) using disposable bailers because of low recharge conditions; and P:\162612\Docs\Subsurface Water Sampling 073117\Report.docx Mr. Robert Romero DTSC July 31, 2017 Page 3  Pursuant to DTSC request, a split sample was collected from A12-MW2 and sent to a separate laboratory for analysis. DTSC staff acknowledged and/or approved all referenced deviations. Field Work Notification and Agency Oversight Pursuant to DTSC’s request, Amec Foster Wheeler provided a notice to proceed with proposed field activities on May 23, 2017 after receipt of SBCPH permits. Amec Foster Wheeler also notified SBCPH of our intent to abandon and replace monitoring well A12-MW3. Monitoring well A12-MW3 destruction and replacement occurred on June 5, 2017. DTSC staff, Ms. Wendy Arano, was onsite to observe drilling activities. In addition, SBCPH staff Mr. Gustavo Cervantes was onsite to review well destruction activities. Ms. Wendy Arano was also onsite on June 20, 2017 to observe former Redwater Pond sampling activities. Monitoring Well A12-MW3 Destruction and Replacement Amec Foster Wheeler retained BC2 Environmental (BC2) to destroy and replace monitoring well A12-MW3. For well destruction, the entire well casing from bottom to top was pressure grouted using Portland cement/bentonite slurry placed with tremie pipe pursuant to SBCPH permit requirements. Approximately 50 gallons of slurry mixture was pressure pumped into the casing. Well destruction was confirmed by maintaining a minimum pressure level of 25 pounds per square inch (psi) for 15 minutes. Subsequently, the upper five feet of casing was over-drilled and the void was filled with slurry mixture to surface. Replacement monitoring well A12-MW3R was installed approximately 20 feet south of the original well. An initial boring was drilled by BC2 using hollow-stem auger equipment approximately 20 feet east of the original well, but the boring was “dry”. A second boring was drilled nearby to a depth of approximately 26.5 feet. Unconsolidated silty sand and silt was encountered to a depth of approximately 16 feet, below that silty sandstone and siltstone (bedrock) was encountered. Only moist sediments were encountered in both boreholes and standing water was not observed in either borehole after several hours of waiting. Nonetheless, replacement well A12-MW3R was installed on June 5, 2017 in accordance with the procedures and methodologies described in the Work Plan and California State Well Standards for monitoring wells (California Department of Water Resources, 1991). The replacement monitoring wells A12-MW3R was constructed with 15 feet of 4-inch-diameter, 0.020-inch Schedule 40 polyvinyl chloride (PVC) screen and Schedule 40 PVC blank riser. A filter pack consisting of #2/12 sand was placed in the annular space around the well screen and extended approximately 2 feet above the top of the well screen. An approximate 5-foot thick bentonite seal was placed on top of the filter pack and the remaining annular space was filled with cement-bentonite grout to surface. The monitoring well was completed with a 3-foot tall locking steel monument and surrounded by three protective posts secured in place with cement. P:\162612\Docs\Subsurface Water Sampling 073117\Report.docx Mr. Robert Romero DTSC July 31, 2017 Page 4 The Upper A-12 monitoring well locations, including replacement well A12-MW3R, are shown on Figure 3. A construction log of A12-MW3R is included as Appendix B. Monitoring Well Development, Survey, and Sampling During a site visit on June 8, 2017, three days after replacement well A12-MW3 was installed, approximately 10 feet of water was measured in the well allowing for well development and sampling. Thus, replacement well A12-MW3R was developed on June 14, 2017 using a combination of surging and bailing methods to remove the potential effects of drilling activities and promote communication (water flow) between the well, filter pack, and formation materials. After initial surging, the well was bailed to remove sediments. Approximately 16 gallons of water was bailed before the well went dry. The well remained idle for approximately three hours during which water levels rebounded approximately three feet. The well was resurged and approximately four additional gallons of water was bailed. Field water quality parameters could not be measured and recorded during well development because of the low recharge conditions. However, approximately three saturated well volumes (saturated screen plus filter pack void space) were removed during well development in accordance with the procedures and methodologies described in the Work Plan. Ground surface elevations and coordinates of the monitoring wells were surveyed by CalVada Surveying Inc. (CalVada), a California-licensed land surveyor. The existing and replacement monitoring well locations were surveyed and reported as longitude and latitude relative to the North American Datum of 1983. The ground surface and top-of-casing elevations were surveyed and reported as feet above the North American Vertical Datum of 1988. Monitoring well survey coordinates and elevations are summarized in Table 1. Subsurface water samples were collected on June 19 and 20, 2017 using the procedures and methods described in the Work Plan. All wells were gauged before sampling. Upper A-12 Test Area Subsurface water samples were collected from monitoring wells A12-MW1, A12-MW2 and A12MW3R in the Upper A-12 Test Area on June 19, 2017. The wells contained between 4 and 10 feet of water, which was insufficient for using low-flow purging and sampling methods because of low recharge conditions. Thus, all three wells were bailed dry then allowed to rest for approximately 4 to 5 hours during which water levels rebounded to approximately 50 to 80 percent of the wells original water level. Subsequently, water samples were collected using disposable bailers and transferred into laboratory-supplied containers. Figure 3 shows monitoring well locations in the Upper A-12 Test Area. Redwater Pond Subsurface water samples were collected from monitoring wells MW-1, MW-2, and MW-3 in the Redwater Pond on June 20, 2017. The wells contained between 12 and 49 feet of water, which was sufficient for using low-flow purging and sampling methods. Purging and sampling was P:\162612\Docs\Subsurface Water Sampling 073117\Report.docx Mr. Robert Romero DTSC July 31, 2017 Page 5 conducted using a 2-inch QED Sample Pro pump. The average pumping rate of purging at each well was approximately 225 milliliter per minute (ml/m). After purging, the flow rate was lowered to about 100 ml/m and water samples were collected directly from the discharge tubing into laboratory-supplied containers. Figure 4 shows monitoring well locations in the former Redwater Pond. Analytical Testing The subsurface water samples were placed in a chilled ice chest and picked up by courier from Eurofins Calscience Inc. (Calscience). Calscience is a California Environmental Laboratory Accreditation Program certified laboratory located in Garden Grove, California. Calscience analyzed the three subsurface water samples and one field quality control sample (duplicate sample) from the Upper A12 Test Area for the following:  Perchlorate using United States Environmental Protection Agency (U.S. EPA) Method 314.0.  Uranium using U.S. EPA Method 200.8. Calscience analyzed the three subsurface water samples and two field quality control sample (duplicate and equipment blank sample) from the Redwater Pond for explosive compounds using U.S. EPA Method 8330. Quality Control Sampling Review Duplicate subsurface water samples were collected from monitoring well A12-MW3R in the Upper A-12 Test Area and monitoring well MW-3 in the former Redwater Pond. The duplicate samples designated MWA and MWB, respectively, were submitted “blind” to Calscience and analyzed for the above-listed analytes. An equipment blank was also collected from former Redwater Pond monitoring well MW-3 after the well was sampled. The equipment blank sample designated QCEB was collected by pouring analytically-certified organic-free water (HPLCgrade) over the decontaminated 2-inch QED Sample Pro pump that was used for collecting water samples. Pursuant to DTSC request, a spilt sample was also collected from monitoring well A12-MW2 and transported in a chilled ice chest to Test America Laboratories, Inc. (Test America), a California Environmental Laboratory Accreditation Program certified laboratory located in Irvine, California. The split sample was analyzed for perchlorate using U.S. EPA Method 314.0. SUMMARY OF RESULTS This investigation was performed under the direction of DTSC to re-assess water quality of subsurface water at the site. Summary of results from the Upper A-12 Test Area and former Redwater Pond are provided below. P:\162612\Docs\Subsurface Water Sampling 073117\Report.docx Mr. Robert Romero DTSC July 31, 2017 Page 6 Upper A-12 Test Area Subsurface water samples were collected from monitoring wells A12-MW1, A12-MW2 and A12MW3R in the Upper A-12 Test Area and analyzed as described above. A duplicate and split sample were also collected. Upper A-12 Test Area subsurface water sample results summary are presented below and provided in Table 2.  Perchlorate was detected in only one sample. It was detected in A12-MW1 at a concentration of 11 µg/L.  Perchlorate was not detected in split sample A12-MW2 analyzed by Test America or duplicate sample MWA (primary sample A12-MW3).  Uranium was detected in samples from all three monitoring wells (including the duplicate sample) at concentrations between 294 and 1,920 µg/L. The highest concentration was detected in near-source area sample A12-MW1. Laboratory analytical data sheets for subsurface water samples analyzed by Calscience are included as Appendix C. Laboratory analytical data sheets for the split sample analyzed by Test America are included as Appendix D. Redwater Pond Subsurface water samples were collected from monitoring wells MW-1, MW-2 and MW-3 in the Redwater Pond and analyzed as described above. A duplicate and equipment blank sample were also collected. Former Redwater Pond subsurface water sample results summary are presented below and provided in Table 4.  No explosive compounds were detected in the samples from MW-1 or MW-2.  HMX and RDX were detected in samples from MW-3 and its duplicate MWB as noted below.  o HMX was detected at concentrations of 6.4 and 6.5 µg/L. o RDX was detected in both samples at a concentration of 290 µg/L. No analyte was detected in equipment blank sample QCEB. Laboratory analytical data sheets for subsurface water samples analyzed by Calscience are included as Appendix C. QA/QC Results All proposed samples were collected following the procedures and methodologies described in the Work Plan. The procedures were modified, as described above, based on field conditions, P:\162612\Docs\Subsurface Water Sampling 073117\Report.docx Mr. Robert Romero DTSC July 31, 2017 Page 7 and as deemed necessary. The specified numbers of quality control/quality assurance samples were also collected and analyzed as planned. Two field duplicates, one equipment blank, and one split sample were collected and analyzed using the same methods as used for the primary samples. Primary and duplicate/split sample pair results were assessed using the relative percent difference (RPD) between the primary sample and duplicate/split sample measurements. The precision goal was within 30 percent for water. As noted in Table 3, none of the RPD calculations exceeded the precision goal. CONCLUSIONS Per DTSC request, subsurface water sampling was performed at the Upper A-12 Test Area and former Redwater Pond to re-assess the water quality of subsurface water at these areas of the site. Based on previous subsurface water quality evaluations conducted at the site, several COCs were identified in subsurface water that may have originated from historic site operations. The COCs at the Upper A-12 Test Area included perchlorate and uranium (from historic assembly and testing of depleted uranium munitions at the site). The COCs at the former Redwater Pond included explosive compounds (from wastewater generated during historic assembly of munitions). Recent subsurface water sampling and analysis conducted in 2017 was implemented in general accordance with the procedures and methodologies described in the Work Plan. Table 4 summarizes previous and current (2017) subsurface water samples analyses results from the grab location and monitoring wells located in the Upper A-12 Test Area. Recent concentrations of perchlorate (2017), where detected, were noticeably lower than those reported from previous sampling events in the mid 2000’s indicating a general trend of declining concentrations of COCs in subsurface water. During this recent sampling event, perchlorate was detected in only one subsurface water sample at a low concentration. Current concentrations of uranium are comparable to or slightly higher than those reported from previous sampling events (Table 4) indicating generally stable subsurface water concentrations. The highest concentrations of uranium were detected in sample A12-MW1 located within the boundary of the former test area. Uranium concentrations decrease in wells A12-MW2 and A12-MW3R located topographically downgradient of the former test area. Table 5 summarizes previous and current (2017) subsurface water sample results from the grab location and monitoring wells located in the former Redwater Pond. No explosive compounds have been detected in any of the subsurface water samples from monitoring wells MW-1 and MW-2 located around the perimeter of the former wastewater holding pond. Recent concentrations of RDX and HMX in MW-3 (2017) were lower than those reported from previous sampling events indicating generally a declining trend of subsurface water concentrations. Consistent with the conclusions of the previous subsurface water quality evaluations, the recent (2017) subsurface water sampling results indicate that concentrations of COCs detected in subsurface water are non-detect, or generally declining or stable. Based on the results of the re-assessment of the quality of subsurface water at the site and comparing 2017 sample results with previous sampling results and conclusions, additional subsurface water sampling is not P:\162612\Docs\Subsurface Water Sampling 073117\Report.docx Mr. Robert Romero DTSC July 31, 2017 Page 8 warranted at this time. Options for addressing the COCs detected in subsurface water from the Upper A-12 Test Area and former Redwater Pond will be evaluated based on future land use decision for the entire facility.

Therefore, the sample data was reported without further clarification. 2 Surrogate compound recovery was out of control due to matrix interference. The associated method blank surrogate spike compound was in control and, therefore, the sample data was reported without further clarification. 3 Recovery of the Matrix Spike (MS) or Matrix Spike Duplicate (MSD) compound was out of control due to suspected matrix interference. The associated LCS recovery was in control. 4 The MS/MSD RPD was out of control due to suspected matrix interference. 5 The PDS/PDSD or PES/PESD associated with this batch of samples was out of control due to suspected matrix interference. 6 Surrogate recovery below the acceptance limit. 7 Surrogate recovery above the acceptance limit. B Analyte was present in the associated method blank. BU Sample analyzed after holding time expired. BV Sample received after holding time expired. CI See case narrative. E Concentration exceeds the calibration range. ET Sample was extracted past end of recommended max. holding time. HD The chromatographic pattern was inconsistent with the profile of the reference fuel standard. HDH The sample chromatographic pattern for TPH matches the chromatographic pattern of the specified standard but heavier hydrocarbons were also present (or detected). HDL The sample chromatographic pattern for TPH matches the chromatographic pattern of the specified standard but lighter hydrocarbons were also present (or detected). J Analyte was detected at a concentration below the reporting limit and above the laboratory method detection limit. Reported value is estimated. JA Analyte positively identified but quantitation is an estimate. ME LCS Recovery Percentage is within Marginal Exceedance (ME) Control Limit range (+/- 4 SD from the mean). ND Parameter not detected at the indicated reporting limit. Q SG Spike recovery and RPD control limits do not apply resulting from the parameter concentration in the sample exceeding the spike concentration by a factor of four or greater. The sample extract was subjected to Silica Gel treatment prior to analysis. X % Recovery and/or RPD out-of-range. Z Analyte presence was not confirmed by second column or GC/MS analysis. Solid - Unless otherwise indicated, solid sample data is reported on a wet weight basis, not corrected for % moisture. All QC results are reported on a wet weight basis. Any parameter identified in 40CFR Part 136.3 Table II that is designated as "analyze immediately" with a holding time of <= 15 minutes (40CFR-136.3 Table II, footnote 4), is considered a "field" test and the reported results will be qualified as being received outside of the stated holding time unless received at the laboratory within 15 minutes of the collection time. A calculated total result (Example: Total Pesticides) is the summation of each component concentration and/or, if "J" flags are reported, estimated concentration. Component concentrations showing not detected (ND) are summed into the calculated total result as zero concentrations. 7440 Lincoln Way, Garden Grove, CA 92841-1427 • TEL: (714) 895-5494 • FAX: (714) 894-7501 Return to Contents Qualifiers Page 1 of 1 Page14of15 #117172179?6176 x93 9%0'8179'6176 IBJ. eswomea ?euw: 002 mans ?enua uonerum LZL 5,3) ?3 x\ IsaaNavmoo :10 ?mm HLVCI ZSLNEWWOO IS CINV EldAl 9939155 ed?i ennemaseJd Oi ELUS i Ml?? :ama 3A8 EWLL BLVCI 009 92m gnu HESWHN BIN :(aam s) ~53 GNHOHVNEDL 301. ??ame 33WVN 080938 .e . 3 Page15 5 egteurofmsi it? i tlieiseienee SAMPLE RECEIPT CHECKLIST CLIENT: Aim DATE: 06/11/2017 TEMPERATURE: (Criteria: not frozen except sediment/tissue) Thermometer ED: 8038 (CF: Temperature (w/o CF): 4? 9?

Therefore, the sample data was reported without further clarification. 2 Surrogate compound recovery was out of control due to matrix interference. The associated method blank surrogate spike compound was in control and, therefore, the sample data was reported without further clarification. 3 Recovery of the Matrix Spike (MS) or Matrix Spike Duplicate (MSD) compound was out of control due to suspected matrix interference. The associated LCS recovery was in control. 4 The MS/MSD RPD was out of control due to suspected matrix interference. 5 The PDS/PDSD or PES/PESD associated with this batch of samples was out of control due to suspected matrix interference. 6 Surrogate recovery below the acceptance limit. 7 Surrogate recovery above the acceptance limit. B Analyte was present in the associated method blank. BU Sample analyzed after holding time expired. BV Sample received after holding time expired. CI See case narrative. E Concentration exceeds the calibration range. ET Sample was extracted past end of recommended max. holding time. HD The chromatographic pattern was inconsistent with the profile of the reference fuel standard. HDH The sample chromatographic pattern for TPH matches the chromatographic pattern of the specified standard but heavier hydrocarbons were also present (or detected). HDL The sample chromatographic pattern for TPH matches the chromatographic pattern of the specified standard but lighter hydrocarbons were also present (or detected). J Analyte was detected at a concentration below the reporting limit and above the laboratory method detection limit. Reported value is estimated. JA Analyte positively identified but quantitation is an estimate. ME LCS Recovery Percentage is within Marginal Exceedance (ME) Control Limit range (+/- 4 SD from the mean). ND Parameter not detected at the indicated reporting limit. Q SG Spike recovery and RPD control limits do not apply resulting from the parameter concentration in the sample exceeding the spike concentration by a factor of four or greater. The sample extract was subjected to Silica Gel treatment prior to analysis. X % Recovery and/or RPD out-of-range. Z Analyte presence was not confirmed by second column or GC/MS analysis. Solid - Unless otherwise indicated, solid sample data is reported on a wet weight basis, not corrected for % moisture. All QC results are reported on a wet weight basis. Any parameter identified in 40CFR Part 136.3 Table II that is designated as "analyze immediately" with a holding time of <= 15 minutes (40CFR-136.3 Table II, footnote 4), is considered a "field" test and the reported results will be qualified as being received outside of the stated holding time unless received at the laboratory within 15 minutes of the collection time. A calculated total result (Example: Total Pesticides) is the summation of each component concentration and/or, if "J" flags are reported, estimated concentration. Component concentrations showing not detected (ND) are summed into the calculated total result as zero concentrations. 7440 Lincoln Way, Garden Grove, CA 92841-1427 • TEL: (714) 895-5494 • FAX: (714) 894-7501 Return to Contents Qualifiers Page 1 of 1 Page150f16 SLNEIININOC) WVNOLLIGCJV smugewog go '05: 9V6 vwv'zvg'avs X93 9v20'2v9'6176 I91. vans-ugzs eswomeo ?euw: 002 91an ?eAua uonerum LZL ismawwoo Isaamvmoo 30 832mm wmi 3.040 EZES CINV 2 muemasaJd PaJalilzl SEISAWVNV 3?di33d3 HMS 83M DWELOEB ismawamnuau iNBl'lO OZ ?39 049? 4-- 33WVN lad i: 1A8 GENE-1038 BWLL ELVG (ll-EA 5" max 2% ?3 00m ?Micah? 1y aaewnw aw awe 31dwvs ONQOHVNUFLL 30.1. snnsau .Loaroad 33WVN 080333 - Page 16 1 eurofms WORK ORDER NUMBER: 17-06- $17269 Ceienienee A SAMPLE RECEIPT CHECKLIST COOLER OF AWL DATE: 06 1,,29_ 2017 TEMPERATURE: (Criteria: not frozen'except sediment/tissue) Thermometer ID: 8038 (CF: Temperature (w/O CF): 3 22 :2 El Blank ?ample Sampie(s) outside temperature criteria contacted by: El Sampie(s) outside temperature criteria but received on ice/chilled on same day Of sampling El Sample(s) received at ambient temperature; pieced on ice for transport by courier Ambient Temperature: Ci Air 8 Filter Checked by: 827$ CUSTODY SEAL: Cooler El Present and Intact [3 Present but Not Intact gl/thPresent i3 Checked by: 5?79 Sample(s) [1 Present and intact [3 Present but Not intact Present l3 Checked by: 9?79 SAMPLE CONDITION: 7 Yes NO El COCdocument(s)receivedcomplete . /El/ Sampiing date Sampiing time El Matrix 1] Number of containers No analysis requested Not reiinquished El NO relinquished date No relinquished time Sampler?s name indicated 9/ E3 COC El Sample container(s) intact and in good condition 21/ El El Proper containers for analyses requested lg/ Sufficient volume/mass for analyses requested CI Sampies receivedwithin holdingtime 121/ Cl [3 Aqueous samples for certain anaiyses received within 15-minute holding time pH Residual Chlorine El Dissolved Sulfide Dissolved Oxygen El CI Proper preservation chemical(s) noted on COC and/or sample container Unpreserved aqueous sample(s) received for certain anaiyses Volatile Organics El Total Metals Dissolved Metals Container(s)forcertain analysisfreeofheadspace El Ci Votatile Organics ELI Dissoived Gases (RSK-175) ?3 Dissoived Oxygen (SM 4500) El Carbon Dioxide (SM 4500) Ferrous Iron (SM 3500) Hydrogen Sulfide (Hach) 'I'edlarTM bag(s) free Of condensation 5/ TYPE: (Trip Blank Lot Number: Aqueous: Ei [3 El 100PJ Cl 100PJnaz Ci 125AGB [3 125PB 125382? 25OAGB E3 ZSOCGB El ZSOCGBS 250PB SOOAGB [If 5OOAGJ Ci SOOAGJS El SOOPB El 1AGBnaz El 1PBna I3 Solid: [3 Ci 80206.] El 16OZCGJ l2] Sleeve if} EnCores?
