CRHC 208 Fourth Quarter Monitoring Report November 9, 208 EBA Engineering Project No. 4070-00 Page.0 Introduction The Chester River Hospital Center (Hospital) is located at 00 Brown Street, Chestertown, in Kent County, Maryland. Circa June 987, the Hospital notified the Maryland Department of the Environment (Department) of tank test failures for a,000- gallon #2 heating oil UST and a 0,000-gallon #2 heating oil UST servicing the Hospital. In 989, monitoring wells were installed, and testing of those wells revealed oil had impacted groundwater on-site. The Department determined the Hospital was responsible for the discharge of oil at the Site. Since discovery of the release, the Hospital has cooperated with the Department in the remediation of the Site. In May of 99, the Hospital installed a groundwater remediation system to recover liquid phase heating oil from the subsurface and contain the dissolved product plume on the Site. By July 999, a total of 66,287 gallons of oil had been recovered. Also in 999, three groundwater recovery wells were replaced. In 200 and 2002, the groundwater treatment system was upgraded to address a significant decrease in product recovery per month. The upgrades included additional recovery and monitoring wells and new product recovery pumps. By March 202, approximately 83,428 gallons of liquid phase heating oil had been recovered. In July 202, the Hospital was given approval for a trial shutdown of the pump and treat system to assess whether the constituents of concern were sufficiently remediated. During this time, regular monitoring of site wells continued on a monthly schedule. In June 203, the routine monitoring detected an increase in contamination levels and the Hospital notified the Department that it was restarting the pump and treat system. In July 203, Chester River Hospital Center and Shore Health System were merged to form University of Maryland Shore Regional Health. For reference and location purposes, Chester River Hospital Center and University of Maryland Shore Regional Health are one in the same (Hospital). With the Department s approval, in 204, the Hospital implemented a pilot study to demonstrate the viability of a soil cleansing product known as Ivey-sol (surfactant). The pilot study demonstrated that the surfactant process could be performed safely and could effectively liberate and remove sorbed residual hydrocarbons. In January 205, the Hospital submitted a Groundwater Remediation Pilot Test Evaluation Report and Proposed 205 Action Plan. On July 22, 205, the Department approved a revised 205 Action Plan (CAP). Under the Approved CAP, the Hospital began the surfactant injection and extraction events in August 205 and concluded them in March 206.

CRHC 208 Fourth Quarter Monitoring Report November 9, 208 EBA Engineering Project No. 4070-00 Page 2 On May, 206, a Settlement Agreement and Consent Order (Consent Order) was executed between the Hospital and the Department. The Consent Order details the requirements of the Hospital and provides direction for achieving case closure. Site activities that have occurred since May, 206 are the result of the Consent Order. Status updates as related to the Consent Order will be included in future reports. A summary of work to be performed by the Hospital per the Consent Order and their status include the following: Paragraph 35 The Hospital shall implement the Approved CAP in accordance with its terms, including any amendments thereto. (Status Completed.) Paragraph 36 Any subsequent amendments to the Approved CAP must be in writing and executed by both parties. (Status Approved CAP completed. No amendments required.) Paragraph 37 Parties may choose to address Minor Technical Modifications to the Approved CAP in accordance with the Minor Technical Modifications provisions of the Consent Order. (Status - Approved CAP completed. No minor technical modifications required.) Paragraph 38 Once the Approved CAP has been completed, the Hospital shall continue monthly and quarterly sampling of the Department designated monitoring wells including laboratory testing for appropriate constituents as previously directed by the Department, including using EPA Method 8260 for volatile organic compounds, fuel oxygenates, and naphthalene and using EPA Method 805 for TPH-DRO. The Hospital shall also begin monitoring groundwater quarterly for surfactants using EPA Method 5540D until surfactants are no longer detected in any of the site wells. The Hospital shall submit quarterly reports of the sampling and analysis pursuant to the Department s schedule. (Status Ongoing. Monitoring currently being performed in accordance with Department s letter dated December 20, 206. Based upon the results from January 208 sampling event, surfactants were no longer detected in any of the site wells.) Paragraph 39 Monthly and quarterly sampling shall continue pursuant to ongoing Department monitoring requirements until project closure or upon written determination by the Department that the existing quarterly and monthly monitoring is to be replaced with a revised/updated monitoring plan. (Status Ongoing. Monitoring currently being performed in accordance with Department s letter dated December 20, 206.) Paragraph 40 The Department and the Hospital have discussed the need to install several monitoring wells on the site for the collective purposes of logging soil types with depth, collecting soil samples with depth, collecting groundwater samples, and determining the presence of LPH with depth. The Department will send a request for a work plan to the Hospital for this purpose. The Hospital will submit a work plan for the Department s approval. The Department will review the work plan and approve it, or approve it with modifications. The Hospital will complete the approved work plan within the time frames specified by the Department. The Hospital will compile all data collected from this soil boring investigation into a comprehensive report to be submitted to the Department at the time to be specified in the work plan approval. (Status - Completed.)

CRHC 208 Fourth Quarter Monitoring Report November 9, 208 EBA Engineering Project No. 4070-00 Page 3 Paragraph 4 Once surfactants are no longer detected by the laboratory analysis and TPH-DRO concentrations are at or less than part per million (equivalent to milligram per liter), the Hospital may submit to the Department a request to turn off the pump and treat system and begin post-remedial monitoring. (Status Surfactants are no longer detected by laboratory analysis. Select wells, as discussed in Section 4, show TPH-DRO concentrations greater than part per million.) Paragraphs 42 47 are related to post-remedial monitoring and case closure requirements. Their inclusion is not warranted at this time as a limited number of monitoring wells contain TPH-DRO concentrations greater than milligram per liter. 2.0 Investigation Methods The Site contains 49 wells that are monitored on a monthly basis. This includes 40 monitoring wells (MW), 6 recovery wells (RW), and 3 sentinel wells (S). A summary of activities conducted during this monitoring period (August, 208 through October 3, 208) are presented as follows. August Monthly Monitoring o Gauging of all monitoring, recovery, and sentinel wells. September Monthly Monitoring o Gauging of all monitoring, recovery, and sentinel wells. October Monthly Monitoring o Gauging of all monitoring, recovery, and sentinel wells. o Sampling of all monitoring, recovery, and sentinel wells for the presence of Total Petroleum Hydrocarbons - Diesel Range Organics (TPH-DRO) using EPA Method 805. o Sampling of all monitoring, recovery, and sentinel wells for the presence of Volatile Organic Compounds (VOCs), including oxygenates, using EPA Method 8260B. o Sampling of MW-9, MW-0R, MW-, MW-3, MW-4, MW-20, MW-37, MW-4, MW-43, MW-45, MW-46, MW-47, MW-5, MW-53, and MW-54 for the presence of TPH DRO with and without Silica Gel Cleanup. (See note regarding Silica Gel Cleanup below).

CRHC 208 Fourth Quarter Monitoring Report November 9, 208 EBA Engineering Project No. 4070-00 Page 4 Note: Silica Gel Cleanup As introduced in the 207 Amended Third Quarter Monitoring Report, the silica gel cleanup (SGC) method was used to separate the polar non-petroleum hydrocarbons from the hydrocarbons in the sample extract prior to quantification of TPH-DRO. As a polar material, silica gel will adsorb polar nonhydrocarbons present in the sample. As a result, hydrocarbons, which are nonpolar in molecular structure, are not adsorbed by the silica gel and will remain to be appropriately quantified as TPH-DRO (Zemo et al. 203). Utilization of the SGC method provides the most accurate results for quantification of TPH-DRO. Laboratory Analysis Phase Separation Science (Phase) was retained to perform the analysis of TPH-DRO using EPA Method 805, VOCs using EPA Method 8260B, and TPH-DRO analysis with SGC method. Phase is accredited through the National Environmental Laboratory Accreditation Program (NELAP). In addition, Phase is certified by the Maryland Department of the Environment Water Supply Program as a State Certified Water Quality Laboratory. A copy of all laboratory results performed by Phase are included in Appendix A. 3.0 Local/Regional Geology and Hydrology Surface water from the Hospital property eventually drains into the Chester River through the storm water drainage system. The Chester River is a tidal tributary of the Chesapeake Bay and enters the bay approximately 5 miles southwest of Chestertown. Chestertown is in the south-central portion of Kent County within the Eastern Shore of Maryland. The Eastern Shore is part of the Delmarva Peninsula, a peninsula occupied by most of Delaware and the eastern shores of Maryland and Virginia. Although called a peninsula, it became an island after the digging of the Chesapeake and Delaware Canal. It is bordered by the Chesapeake Bay on the west, the Delaware River, Delaware Bay, and the Atlantic Ocean on the east, and the Elk River and its isthmus on the north. The project site lies in the Atlantic Coastal Plain physiographic province. According to the Geologic Map of Kent County, Maryland, published in 968 by the Maryland Geological Survey, the soils in the region are characterized by a thick accumulation of alluvial and marine deposits spanning from the Cretaceous Age to the present. The Hospital is underlain by the Upland Deposits formation of the Quaternary Age. The Upland Deposits formation consists of gravel and sand, which are commonly white to red. They are mostly cross-bedded, poorly sorted, medium to coarse grained sand and gravel. Pink and yellow silts and clays may also be present within the Deposits. Thickness of the Upland Deposits formation ranges from 0 to 90 feet.

CRHC 208 Fourth Quarter Monitoring Report November 9, 208 EBA Engineering Project No. 4070-00 Page 5 Under non-pumping conditions, the water table fluctuates seasonally between 30 to 55 feet below ground surface depending on location. Natural groundwater flow direction is towards the southeast and the Chester River. The water-table contour map, Figure, shows a depression in the upper parking lot (source area) created by the groundwater recovery/containment system. 4.0 s of Work Performed Sampling Methodology BrightFields, Inc. (BFI) was responsible for performing all field activities associated with gauging and groundwater sample collection. BFI s sampling procedure requires the utilization of disposable nitrile gloves for gauging, sampling, and decontamination activities. Gauging is performed using an oil-water interface probe. The interface probe is decontaminated prior to use and after use at each well. BFI s decontamination procedures include washing equipment with Alconox followed by rinsing with deionized water. The depth to product, if present, and the depth to water is recorded to within 0.0 feet. Purging and sampling of wells are performed in order of increasing chemical concentrations. BFI s sampling procedures requires the removal of three well volumes prior to sampling. Purged water is treated on-site via granular activated carbon prior to discharge. Water samples are collected using new disposable polyethylene bailers. A new bailer is required for each well. VOC samples are collected first and directly into prepreserved sample containers. Care is taken to fill sample containers with minimal turbulence. Samples are then placed directly into coolers containing ice for delivery to the laboratory. All samples are shipped under laboratory chain of custody protocol. Gauging Gauging of all monitoring, recovery, and sentinel wells was performed on August 3 st, 208, September 9 th, 208, and October 6 th, 208. None of the monitoring and recovery wells showed a measurable thickness (>0.0') of liquid phase hydrocarbons during gauging activities. Well gauging and field reports are included in Appendix B. Refer to Table for gauging data since June 202. Total Petroleum Hydrocarbons Diesel Range Organics Refer to Table for a summary of TPH-DRO laboratory results. The results of the laboratory analysis show detectable levels of TPH-DRO, the primary contaminant of concern, are present at the Site. With the exception of MW-20 at 2.8 mg/l, the locations of monitoring and recovery wells with detectable levels of TPH-DRO are north of Brown Street. All remaining monitoring and sentinel wells south of Brown Street were below

CRHC 208 Fourth Quarter Monitoring Report November 9, 208 EBA Engineering Project No. 4070-00 Page 6 laboratory detection limits for TPH-DRO. A site map showing concentrations of TPH- DRO is included in Figure 2. Laboratory results for this monitoring period are included in Appendix A. TPH-DRO Silica Gel Cleanup For the October 8 th, 208 sampling event, Phase was tasked to perform the TPH-DRO analysis with and without the SGC method. This sampling event included: MW-9, MW- 0R, MW-, MW-3, MW-4, MW-20, MW-37, MW-4, MW-43, MW-45, MW-46, MW- 47, MW-5, MW-53, and MW-54. In reviewing the results, the utilization of the SGC method resulted in a significant reduction of TPH-DRO in comparison to the results without the utilization of the SGC method. The results showed an arithmetic average percent reduction in TPH-DRO concentrations of 5 when utilizing the SGC method. With the reduction in TPH-DRO concentrations, this resulted in ten of the fifteen monitoring wells showing TPH-DRO concentrations of less than.0 mg/l during the October 8 th sampling event. Refer to Table 3 for a summary of TPH-DRO analysis with and without the SGC method. Volatile Organic Compounds The contaminants of concern within the VOCs include, Benzene, Toluene, Ethylbenzene, Xylenes (collectively referenced as BTEX), and Naphthalene. With respect to all monitoring, recovery, and sentinel wells, the results of laboratory analysis show detectable levels of Benzene, Ethylbenzene, Xylene, and Naphthalene are north of Brown Street. All monitoring and sentinel wells south of Brown Street were below laboratory detection limits for BTEX and Naphthalene. A site map showing concentrations of BTEX and Naphthalene is included in Figure 3. Refer to Table for a summary of BTEX and Naphthalene laboratory results since June 202. Laboratory results for this monitoring period are included in Appendix A. Conclusions Gauging In reviewing all monitoring, recovery, and sentinel well gauging data, the Site continues to demonstrate no detections of liquid phase hydrocarbons in the wells down-gradient from the original release and the Hospital s property line. Total Petroleum Hydrocarbons Diesel Range Organics With the exception of the 5 MWs that underwent further testing via SGC and discussed below, the remaining 34 monitoring, recovery, and sentinel wells continue to show TPH- DRO concentrations less than.0 mg/l. Further, all of the monitoring and sentinel wells located south of Brown Street were below laboratory detection limits for TPH-DRO during

CRHC 208 Fourth Quarter Monitoring Report November 9, 208 EBA Engineering Project No. 4070-00 Page 7 this monitoring period. The Site continues to demonstrate the low levels of dissolved phase petroleum constituents are within the majority of the monitoring well network and within the limits of the Hospital. Further, the monitoring and sentinel wells located along the Hospital s down-gradient property line remain below laboratory detection limits for TPH-DRO. TPH-DRO Silica Gel Cleanup Since implementation of the SGC testing in July 207, the utilization of the SGC method resulted in a significant reduction of TPH-DRO in comparison to the results without the utilization of the SGC method. Of the 5 MWs that historically showed TPH-DRO concentrations greater than.0 mg/l, Tables 2 & 3 shows all 5 MWs have met the TPH- DRO concentration of less than.0 mg/l criteria during at least one monitoring event. Volatile Organic Compounds In reviewing all monitoring, recovery, and sentinel wells, the results of laboratory analysis show detectable levels of Benzene, Ethylbenzene, and Xylenes present at the site are below MDE's Groundwater Cleanup Standards except for MW-47. A Benzene concentration of 6.3 µg/l was detected at MW-47 exceeding the MDE Groundwater Cleanup Standard of µg/l. MW-47 is located north of Brown Street and within the area of hydraulic control imposed by the pump and treat system. 6.0 Recommendations In accordance with the Consent Order and the Department s Site Status Letter dated December 20, 206, the Hospital will perform the following during the next quarterly monitoring period: Monthly gauging of all monitoring, recovery, and sentinel wells. Sampling of all monitoring, recovery, and sentinel wells for the presence of Total Petroleum Hydrocarbons - Diesel Range Organics (TPH-DRO) using EPA Method 805. Sampling of all monitoring, recovery, and sentinel wells for the presence of Volatile Organic Compounds (VOCs), including oxygenates, using EPA Method 8260B. In addition, the Hospital will sample MW-9, MW-0R, MW-, MW-3, MW-4, MW-20, MW-37, MW-4, MW-43, MW-45, MW-46, MW-47, MW-5, MW-53, and MW-54 for the presence of TPH DRO with and without the SGC method. Going forward, it is recommended the continued utilization of the SGC method for achieving the most accurate results for comparison to the requirements in the Consent Order. E OF REPORT

Any sample conditions not in compliance with sample acceptance criteria are described in Case Narrative Summary. Notes:. The presence of a common laboratory contaminant such as methylene chloride may be considered a possible laboratory artifact. Where observed, appropriate consideration of data should be taken. 2. Unless otherwise noted in the case narrative, results are reported on a dry weight basis with the exception of ph, flashpoint, moisture, and paint filter test. 3. Drinking water samples collected for the purpose of compliance with SDWA may not be suitable for their intended use unless collected by a certified sampler [COMAR 26.08.07.C.2]. 4. The analyses of,2-dibromo-3-chloropropane (DBCP) and,2-dibromoethane (EDB) by EPA 524.2 and calcium, magnesium, sodium and iron by EPA 200.8 are not currently promulgated for use in testing to meet the Safe Drinking Water Act and as such cannot be used for compliance purposes. The listings of the current promulgated methods for testing in compliance with the Safe Drinking Water Act can be found in the 40 CFR part 4., for the primary drinking water contaminates, and part 4.3, for the secondary drinking water contaminates. 5. Sample prepared under EPA 3550C with concentrations greater than 20 mg/kg should employ the microtip extraction procedure if required to meet data quality objectives. 6. The analysis of acrolein by EPA 624 must be analyzed within three days of sampling unless ph is adjusted to 4-5 units [40 CFR part 36.3(e)]. 7. Method 80., The Determination of Turbidity by Nephelometry, recommends samples over 40 NTU be diluted until the turbidity falls below 40 units. Routine samples over 40 NTU may not be diluted as long as the data quality objectives are not affected. 8. Alkalinity results analyzed by EPA 30.2 that are reported by dilution are estimated and are not in compliance with method requirements. Page 3 of 79 Version.000

Work Order Number(s): Standard s/abbreviations: B C E Fail J MDL RL U Sample Summary Client Name: UMM Shore Regional Health Chestertown 80726 A target analyte or common laboratory contaminant was identified in the method blank. Its presence indicates possible field or laboratory contamination. s Pending Final Confirmation. The data exceeds the upper calibration limit; therefore, the concentration is reported as estimated. The result exceeds the regulatory level for Toxicity Characteristic (TCLP) as cited in 40 CFR 26.24 Table. The target analyte was positively identified below the reporting limit but greater than the MDL. This is the Laboratory Method Detection Limit which is equivalent to the Limit of Detection (LOD). The LOD is an estimate of the minimum amount of a substance that an analytical process can reliably detect. This value will remain constant across multiple similar instrumentation and among different analysts. An LOD is analyte and matrix specific. Not Detected at or above the reporting limit. PSS Reporting Limit. Not detected.

Work Order Number(s): Case Narrative Summary Client Name: UMM Shore Regional Health Chestertown 80726 Any holding time exceedances, deviations from the method specifications, regulatory requirements or variations to the procedures outlined in the PSS Quality Assurance Manual are outlined below. The analyses of chlorine, ph, dissolved oxygen, temperature and sulfite for drinking water and non-potable samples tested for compliance have a maximum holding time of 5 minutes. As such, all laboratory analyses for these analytes exceed holding times. Matrix spike and matrix spike duplicate analyses may not be performed due to insufficient sample quantity. In these instances, a laboratory control sample and laboratory control sample duplicate are analyzed unless otherwise noted or specified in the method. Unless otherwise noted, surrogate recoveries outside of the acceptance criteria are most often the result of sample matrix interference and/or sample dilution.

October 24, 208 Ken Hannon UMM Shore Regional Health Chestertown 00 Brown Street Chestertown, MD 2620 Reference: PSS Work Order(s) No: 80727 Project Location: Chestertown, MD Dear Ken Hannon : This report includes the analytical results from the analyses performed on the samples received under the project name referenced above and identified with the Phase Separation Science (PSS) Work Order(s) numbered 80727. All work reported herein has been performed in accordance with current NELAP standards, referenced methodologies, PSS Standard Operating Procedures and the PSS Quality Assurance Manual unless otherwise noted in the Case Narrative Summary. PSS is limited in liability to the actual cost of the sample analysis done. PSS reserves the right to return any unused samples, extracts or related solutions. Otherwise, the samples are scheduled for disposal, without any further notice, on November 2, 208, with the exception of air canisters which are cleaned immediately following analysis. This includes any samples that were received with a request to be held but lacked a specific hold period. It is your responsibility to provide a written request defining a specific disposal date if additional storage is required. Upon receipt, the request will be acknowledged by PSS, thus extending the storage period. This report shall not be reproduced except in full, without the written approval of an authorized PSS representative. A copy of this report will be retained by PSS for at least 5 years, after which time it will be disposed of without further notice, unless prior arrangements have been made. We thank you for selecting Phase Separation Science, Inc. to serve your analytical needs.

Work Order Number(s): Sample Summary Client Name: UMM Shore Regional Health Chestertown 80727 The following samples were received under chain of custody by Phase Separation Science (PSS) on 0/7/208 at 03:20 pm Lab Sample Id Sample Id Matrix /Time Collected 80727-00 MW20 GROU WATER 0/7/8 3:30 Please reference the Chain of Custody and Sample Receipt Checklist for specific container counts and preservatives. Any sample conditions not in compliance with sample acceptance criteria are described in Case Narrative Summary. Notes:. The presence of a common laboratory contaminant such as methylene chloride may be considered a possible laboratory artifact. Where observed, appropriate consideration of data should be taken. 2. Unless otherwise noted in the case narrative, results are reported on a dry weight basis with the exception of ph, flashpoint, moisture, and paint filter test. 3. Drinking water samples collected for the purpose of compliance with SDWA may not be suitable for their intended use unless collected by a certified sampler [COMAR 26.08.07.C.2]. 4. The analyses of,2-dibromo-3-chloropropane (DBCP) and,2-dibromoethane (EDB) by EPA 524.2 and calcium, magnesium, sodium and iron by EPA 200.8 are not currently promulgated for use in testing to meet the Safe Drinking Water Act and as such cannot be used for compliance purposes. The listings of the current promulgated methods for testing in compliance with the Safe Drinking Water Act can be found in the 40 CFR part 4., for the primary drinking water contaminates, and part 4.3, for the secondary drinking water contaminates. 5. Sample prepared under EPA 3550C with concentrations greater than 20 mg/kg should employ the microtip extraction procedure if required to meet data quality objectives. 6. The analysis of acrolein by EPA 624 must be analyzed within three days of sampling unless ph is adjusted to 4-5 units [40 CFR part 36.3(e)]. 7. Method 80., The Determination of Turbidity by Nephelometry, recommends samples over 40 NTU be diluted until the turbidity falls below 40 units. Routine samples over 40 NTU may not be diluted as long as the data quality objectives are not affected. 8. Alkalinity results analyzed by EPA 30.2 that are reported by dilution are estimated and are not in compliance with method requirements. Standard s/abbreviations: B C E Fail J MDL RL U A target analyte or common laboratory contaminant was identified in the method blank. Its presence indicates possible field or laboratory contamination. s Pending Final Confirmation. The data exceeds the upper calibration limit; therefore, the concentration is reported as estimated. The result exceeds the regulatory level for Toxicity Characteristic (TCLP) as cited in 40 CFR 26.24 Table. The target analyte was positively identified below the reporting limit but greater than the MDL. This is the Laboratory Method Detection Limit which is equivalent to the Limit of Detection (LOD). The LOD is an estimate of the minimum amount of a substance that an analytical process can reliably detect. This value will remain constant across multiple similar instrumentation and among different analysts. An LOD is analyte and matrix specific. Not Detected at or above the reporting limit. PSS Reporting Limit. Not detected.

Work Order Number(s): Case Narrative Summary Client Name: UMM Shore Regional Health Chestertown 80727 Any holding time exceedances, deviations from the method specifications, regulatory requirements or variations to the procedures outlined in the PSS Quality Assurance Manual are outlined below. The analyses of chlorine, ph, dissolved oxygen, temperature and sulfite for drinking water and non-potable samples tested for compliance have a maximum holding time of 5 minutes. As such, all laboratory analyses for these analytes exceed holding times. Matrix spike and matrix spike duplicate analyses may not be performed due to insufficient sample quantity. In these instances, a laboratory control sample and laboratory control sample duplicate are analyzed unless otherwise noted or specified in the method. Unless otherwise noted, surrogate recoveries outside of the acceptance criteria are most often the result of sample matrix interference and/or sample dilution. Quality control samples that display a high bias will not be narrated when sample target compounds are not detected. Sample Receipt: All sample receipt conditions were acceptable. NELAP accreditation was held for all analyses performed unless noted below. See www.phaseonline.com for complete PSS scope of accreditation. Page 5 of 0 Version.000

Any sample conditions not in compliance with sample acceptance criteria are described in Case Narrative Summary. Notes:. The presence of a common laboratory contaminant such as methylene chloride may be considered a possible laboratory artifact. Where observed, appropriate consideration of data should be taken. 2. Unless otherwise noted in the case narrative, results are reported on a dry weight basis with the exception of ph, flashpoint, moisture, and paint filter test. 3. Drinking water samples collected for the purpose of compliance with SDWA may not be suitable for their intended use unless collected by a certified sampler [COMAR 26.08.07.C.2]. 4. The analyses of,2-dibromo-3-chloropropane (DBCP) and,2-dibromoethane (EDB) by EPA 524.2 and calcium, magnesium, sodium and iron by EPA 200.8 are not currently promulgated for use in testing to meet the Safe Drinking Water Act and as such cannot be used for compliance purposes. The listings of the current promulgated methods for testing in compliance with the Safe Drinking Water Act can be found in the 40 CFR part 4., for the primary drinking water contaminates, and part 4.3, for the secondary drinking water contaminates. 5. Sample prepared under EPA 3550C with concentrations greater than 20 mg/kg should employ the microtip extraction procedure if required to meet data quality objectives. 6. The analysis of acrolein by EPA 624 must be analyzed within three days of sampling unless ph is adjusted to 4-5 units [40 CFR part 36.3(e)]. 7. Method 80., The Determination of Turbidity by Nephelometry, recommends samples over 40 NTU be diluted until the turbidity falls below 40 units. Routine samples over 40 NTU may not be diluted as long as the data quality objectives are not affected. 8. Alkalinity results analyzed by EPA 30.2 that are reported by dilution are estimated and are not in compliance with method requirements. Standard s/abbreviations: B C E Fail J MDL RL U A target analyte or common laboratory contaminant was identified in the method blank. Its presence indicates possible field or laboratory contamination. s Pending Final Confirmation. The data exceeds the upper calibration limit; therefore, the concentration is reported as estimated. The result exceeds the regulatory level for Toxicity Characteristic (TCLP) as cited in 40 CFR 26.24 Table. The target analyte was positively identified below the reporting limit but greater than the MDL. This is the Laboratory Method Detection Limit which is equivalent to the Limit of Detection (LOD). The LOD is an estimate of the minimum amount of a substance that an analytical process can reliably detect. This value will remain constant across multiple similar instrumentation and among different analysts. An LOD is analyte and matrix specific. Not Detected at or above the reporting limit. PSS Reporting Limit. Not detected. Page 3 of 6 Version.000

Work Order Number(s): Case Narrative Summary Client Name: UMM Shore Regional Health Chestertown 80825 Any holding time exceedances, deviations from the method specifications, regulatory requirements or variations to the procedures outlined in the PSS Quality Assurance Manual are outlined below. The analyses of chlorine, ph, dissolved oxygen, temperature and sulfite for drinking water and non-potable samples tested for compliance have a maximum holding time of 5 minutes. As such, all laboratory analyses for these analytes exceed holding times. Matrix spike and matrix spike duplicate analyses may not be performed due to insufficient sample quantity. In these instances, a laboratory control sample and laboratory control sample duplicate are analyzed unless otherwise noted or specified in the method. Unless otherwise noted, surrogate recoveries outside of the acceptance criteria are most often the result of sample matrix interference and/or sample dilution. Quality control samples that display a high bias will not be narrated when sample target compounds are not detected. Sample Receipt: All sample receipt conditions were acceptable. Analytical: DRO - with silica gel column cleanup Batch: 58395 Sample 80825-005 (Silica Gel Treated) correlates with sample 80826-007 (DRO). The patterns obtained from sample analysis resemble that of diesel fuel and are not indicative of surfactants. The calculated value for 80825-005 is larger than that of 80826-007 with an RPD of 3.7 between them. NELAP accreditation was held for all analyses performed unless noted below. See www.phaseonline.com for complete PSS scope of accreditation. Page 8 of 6 Version.000

Work Order Number(s): Sample Summary Client Name: UMM Shore Regional Health Chestertown 80826 Notes:. The presence of a common laboratory contaminant such as methylene chloride may be considered a possible laboratory artifact. Where observed, appropriate consideration of data should be taken. 2. Unless otherwise noted in the case narrative, results are reported on a dry weight basis with the exception of ph, flashpoint, moisture, and paint filter test. 3. Drinking water samples collected for the purpose of compliance with SDWA may not be suitable for their intended use unless collected by a certified sampler [COMAR 26.08.07.C.2]. 4. The analyses of,2-dibromo-3-chloropropane (DBCP) and,2-dibromoethane (EDB) by EPA 524.2 and calcium, magnesium, sodium and iron by EPA 200.8 are not currently promulgated for use in testing to meet the Safe Drinking Water Act and as such cannot be used for compliance purposes. The listings of the current promulgated methods for testing in compliance with the Safe Drinking Water Act can be found in the 40 CFR part 4., for the primary drinking water contaminates, and part 4.3, for the secondary drinking water contaminates. 5. Sample prepared under EPA 3550C with concentrations greater than 20 mg/kg should employ the microtip extraction procedure if required to meet data quality objectives. 6. The analysis of acrolein by EPA 624 must be analyzed within three days of sampling unless ph is adjusted to 4-5 units [40 CFR part 36.3(e)]. 7. Method 80., The Determination of Turbidity by Nephelometry, recommends samples over 40 NTU be diluted until the turbidity falls below 40 units. Routine samples over 40 NTU may not be diluted as long as the data quality objectives are not affected. 8. Alkalinity results analyzed by EPA 30.2 that are reported by dilution are estimated and are not in compliance with method requirements. Standard s/abbreviations: B C E Fail J MDL RL U A target analyte or common laboratory contaminant was identified in the method blank. Its presence indicates possible field or laboratory contamination. s Pending Final Confirmation. The data exceeds the upper calibration limit; therefore, the concentration is reported as estimated. The result exceeds the regulatory level for Toxicity Characteristic (TCLP) as cited in 40 CFR 26.24 Table. The target analyte was positively identified below the reporting limit but greater than the MDL. This is the Laboratory Method Detection Limit which is equivalent to the Limit of Detection (LOD). The LOD is an estimate of the minimum amount of a substance that an analytical process can reliably detect. This value will remain constant across multiple similar instrumentation and among different analysts. An LOD is analyte and matrix specific. Not Detected at or above the reporting limit. PSS Reporting Limit. Not detected.

Work Order Number(s): Case Narrative Summary Client Name: UMM Shore Regional Health Chestertown 80826 Any holding time exceedances, deviations from the method specifications, regulatory requirements or variations to the procedures outlined in the PSS Quality Assurance Manual are outlined below. The analyses of chlorine, ph, dissolved oxygen, temperature and sulfite for drinking water and non-potable samples tested for compliance have a maximum holding time of 5 minutes. As such, all laboratory analyses for these analytes exceed holding times. Matrix spike and matrix spike duplicate analyses may not be performed due to insufficient sample quantity. In these instances, a laboratory control sample and laboratory control sample duplicate are analyzed unless otherwise noted or specified in the method. Unless otherwise noted, surrogate recoveries outside of the acceptance criteria are most often the result of sample matrix interference and/or sample dilution. Quality control samples that display a high bias will not be narrated when sample target compounds are not detected. Sample Receipt: All sample receipt conditions were acceptable. NELAP accreditation was held for all analyses performed unless noted below. See www.phaseonline.com for complete PSS scope of accreditation. Page 9 of 53 Version.000
