Readings were collected at various distances from the concrete pile located at the site following significant rain events, and all resulted in a neutral reading of 7. Please be advised that groundwater sampling was conducted on November 22nd, and we are awaiting results from the analytical laboratory. Upon receiving results, we will compile a Monitoring Report which will include the pH results I’ve attached to this email. Please let me know if you have any questions.

MOVED by Amy von Hone. Seconded by Kimberley Pearson. Roll Call Vote: Vice Chair Amy von Hone – yes, Bruce Evans – yes, Kimberley Pearson – yes, Davis Walters – yes, Chair Cyndi Baran – yes VOTE: 5-yes 0-no Cyndi said she saw some site plans that came in for review and asked Amy if there were any other plans we were waiting for or any summaries. Amy said she didn’t have any additional information with regards to the operation. We haven’t seen any complaints in this office. She did get an email from Kim after our site visit as it relates to some of the high arsenic and manganese data the property has been receiving over the last couple years. Kim said her question was looking at the alkalinization trends and how we are seeing an increasing alkalinity in a couple of the test wells. She did a little bit of background research and found that in a couple of places, they track the pH of their stormwater puddles. It’s not in any regs in MA, but it would be interesting to track where the alkalinity is coming from – it isn’t in MA but is in 22 other states. John Tadema-Wielandt asked how she would suggest we do that, using pH strips? Kim answered, absolutely. If there is ponding after a significant storm, just literally testing the pH of it. It would be nice to know what it is related to as this is not a one-time thing; this has been going on for some time. If that is the case, you might have a much easier explanation of why you are seeing the iron exchange regarding the arsenic and manganese because that is going to happen if you are having acute alkaline flow into your ground water there. John Tadema- Wielandt said he would be willing to do the testing to check. Amy said Jay Merchant has been doing a lot of testing on the site since he took over the property. She thinks he’s made great progress on the property. How expensive will this additional testing be? Were the prior owners of the property also doing concrete crushing and stockpiling? What would be the difference between then and now? Kim said the only reason it would be different then the septic tanks that are put in the ground, is that when you crush concrete, you may inadvertently expose some uncured calcium oxide which is where the alkalinity would come in. John Tadema-Wielandt answered that as far as costs go, it would be a nominal cost, maybe $50. Jay Merchant answered that they took over the property in 2007 and had been doing business with them for 25 years. As long as he could remember, they always took concrete and did their own crushing. John Tadema-Wielandt said the trends they are seeing started semi-recently, but the operations on site have remained constant. It’s kind of a mystery. Amy followed up by asking if there were any mitigating actions seen in other states that do have regulations around this? Kim said it differs from place to place. It’s a tricky process to manage. Sometimes it can’t be mitigated, and the operation has to go someplace else. John Tadema-Wielandt said it makes sense to see some hits in the 3A Well because as that material is removed, when there is a rain event, that can wash some organic material into the aquifer, which could create a reducing environment. Kim said when she thinks of a reducing environment, she would think the pH would be more acidic. John Tadema-Wielandt said the trend is confusing. He is unsure as to why it is happening. Cyndi said it might be worth looking at other areas on the Cape to see what we see for trends. John Tadema-Wielandt said they could also look at Pleasant Bay because his company works at that property as well. Jay Merchant said the pH testing was fine with him and he would talk with John Tadema-Wielandt WQRC Meeting Minutes 6-24-2022 3 about it. Cyndi asked when the next testing round would be. John Tadema-Wielandt said we received the May results a week ago and will be preparing the monitoring report shortly. The next round will be in November. MOTION to approve the certificate of renewal for Cape Sand & Recycling. MOVED by Kimberly Pearson. Seconded by Davis Walters. Roll Call Vote: Vice Chair Amy von Hone – yes, Bruce Evans – yes, Kimberley Pearson – yes, Davis Walters – yes, Chair Cyndi Baran – yes VOTE: 5-yes 0-no Item 4: SBA Infrastructure, M46 L41-10 Freemans Way – hearing for Certificate Renewal Approval Cyndi asked what this was exactly. Amy said she doesn’t know a lot of the history of the properties down in the industrial park. Davis said he was unsure as well. He said this is a communications company and this is a cell tower affiliate. They chose to put in a generator and an above ground propane tank to fuel that generator in the event of power loss. He doesn’t think there’s anything out of the ordinary here as it is common for generators to be placed at the base of cell towers. It was all done to code with permitting, etc. This would be a relatively minor concern in terms of compromising water quality. It would mostly be the internal lubricating parts in the generator itself, but very low volume. MOTION to approve the certificate renewal to SBA Infrastructure. MOVED by Davis Walters. Seconded by Vice Chair Amy von Hone. Roll Call Vote: Vice Chair Amy von Hone – yes, Bruce Evans – yes, Kimberley Pearson – yes, Davis Walters – yes, Chair Cyndi Baran - yes VOTE: 5-yes 0-no Item 5: Discuss meeting format based on Select Board decision Amy said the state has the remote participation for public forums and public hearings sunsetting on July 15th. There has been language included in the state budget to extend the remote format. We have not received any final word that it has been approved. If it does not go through, July 15th is the final deadline for remote meetings. The Select Board has been adapting their format as things have been changing. The most recent change in policy by the Select Board, we are still doing all remote as far as public participation. All committees have the option of doing the remote meetings. There are a couple of boards where they have the option to meet in person or remote. There is no restriction of who or how many can be there in person. As of now, our next meeting will be end of July and we should have a final decision then. The question is going to be if the state does extend the remote meetings, is that how we want to continue? Cyndi is happy to meet remotely unless there is a reason such as a site visit or a large application, she doesn’t see this board to be any less or more effective meeting in person. Kim would defer to town staff and their schedules. She has no issue with it. Amy said she would agree that the majority of our items can be easily discussed remotely, but if there is a larger project coming through, it could be beneficial to be in person at that time. Davis agrees as well. Bruce said he thinks the ability to call in from afar is nice. Cyndi said she thinks, if possible, we could stay remote with this committee. Amy said at this point it makes sense to stay remote unless we hear differently.

I will have to call Monday. 13-I sent a generic email to American Towers to try to find updated contact information for Global Towers Partners/American Towers in Brewster. 14-I reached out to a Chamber of Commerce email for the Brewster VFW, and was told they have no known email directly, but there is a contact phone number. I can try that on Monday, but it looks like that one may have to be mailed. The PO Box online does not match the letter sent 12/2019. We may need to have letterhead and envelopes left somewhere for me to pick up in order to get that one mailed out. I spoke with Sarah, and she acknowledged that the information was not super well organized or up to date (she really hadn’t been supporting WQRC for that long), and is going to look to see if she has anything with more current information. As soon as I hear back, I will begin compiling that listing of businesses and current contacts. Let’s touch base next week with any further updates on those 3 that have not been sent. I knew this would be involved once I got started – lol!

Groundwater sampling was performed by Bennett Environmental Associates, LLC (BEA) on May 24, 2022. The laboratory analyses were performed by Alpha Analytical, as a laboratory certified to perform the requisite analyses. This report, along with the six-month Third -Party Inspector's report, is being filed with the Mass DEP and the BWQRC as part of the conditional approvals for the small WWRF handling facility. 2.0 GROUNDWATER MONITORING PROGRAM 2.1 Background On December 29, 2009, the MassDEP issued a Provisional Approval — Authorization to Operate (ATO) a Small Handling Facility/Wood Waste Reclamation to CS&R. The ATO approval included requirements for continuation of the groundwater monitoring program that had been previously developed to comply with the MassDEP "Wood Waste Reclamation Facilities Siting and Permitting Requirements" Guidance Document - #BWP-98-006 (the WWRF Guidance Document), the Massachusetts Contingency Plan (MCP, 310 CMR 40.0000), and the requirements of the Brewster Water Quality Review Committee (BWQRC). On October 19, 2010, MassDEP issued a Provisional Approval — Modification of a Small Handling Facility/Wood Waste Reclamation Facility, which included a determination deeming the Site Adequately Regulated, pursuant to the applicable provisions of both the MCP and the Solid Waste Regulations (310 CMR 19.00). The Modification Approval also included a reduction in the number of groundwater sampling locations from six (6) to four (4) monitoring wells, including MW -1 (replaced by MW -1R), MW -3A, MW -4A and MW -5. Based on information submitted by the consultant at the time (Prime Engineering), MassDEP found that the reduction in the number of wells would not compromise the sufficiency of the network to monitor groundwater and would remain consistent with the standard Mass DEP requirements for WWRFs. These monitoring wells are routinely sampled for the full list of parameters included in the Groundwater Monitoring Appendix of the WWRF Guidance Document. Total Phosphorus was added as a parameter in November 2015, at the request of the BWQRC. 1 EMERGENCY SPILL RESPONSE e WASTE SITE CLEANUP a SITE ASSESSMENT a PERMITTING a SEPTIC DESIGN & INSPECTION DESIGN BUILD 6 OPERATION & MAINTENANCE 6 WATER SUPPLY DEVELOPMENT 6 WASTEWATER TREATMENT 6 FIELD SERVICES 2 The BWQRC has also requested retaining two (2) additional downgradient monitoring wells (MW-3B and MW-5B) within the monitoring program, to evaluate groundwater conditions up-gradient of the Timberlane Drive neighborhood, where private potable wells are currently in-use. These monitoring wells are typically sampled for Total Manganese to evaluate concentrations in these downgradient wells. Monitoring wells MW-3B and MW-5B are also sampled for nitrogen-related parameters when concentrations of Nitrate/Total Nitrogen are reported above the MMCL of 10 mg/L, in any of the MW-3A, MW-4A or MW-5 monitoring wells. During the May 2022 sampling event, wells MW-3B and MW-5B were also sampled for Total Arsenic, and Total Dissolved Solids due to intermittent spikes in concentrations of these analytes reported in MW-3A in 2020. Monitoring well locations are shown on the enclosed Site Plan. In May 2022 BWQRC personnel requested that BEA test standing water near the ABC processing area to determine if on-site concrete crushing may be raising pH levels in groundwater at the site. BEA plans to test standing water in the ABC processing area using pH strips after rainfall events on a monthly basis. The results will be presented in the next semi-annual monitoring report. 2.2 Groundwater Sample Collection Groundwater samples were collected by BEA personnel on May 24, 2022, from monitoring wells MW-1R, MW-3A, MW-3B, MW-4A, MW-5, and MW-5B. A Monitoring Well Sampling Log is attached for reference. Prior to sampling, depth-to-groundwater measurements were taken at each monitoring well location. The wells were then purged in accordance with MassDEP standard practices and BEA Quality Assurance & Quality Control (QA/QC) methods. Field parameters measured during sampling activities included temperature, pH, conductivity, dissolved oxygen (DO) and oxidation-reduction potential (ORP). The samples were collected using a variable-speed 2” submersible pump, using low-flow sampling methodology. Samples were collected for all required parameters including total metals, as well as dissolved metals, which were field-filtered using an in-line 0.45 Micron filter. The laboratory was instructed to hold the dissolved metals samples pending results of the total metals samples. Sample containers were prepared by Alpha Analytical and kept in a cooler or refrigerator pending pick up by a lab courier and transported following chain of custody procedures. 2.3 Groundwater Gauging Data Well gauging from the date of sampling reports groundwater elevations ranging from 22.62 to 23.28 feet (NGVD), as measured from the top of the well casings. The May 2022 gauging event shows groundwater flows east-northeast towards Pleasant Bay, consistent with data from previous monitoring events. Depth- to-groundwater measurements and corresponding elevations are presented on the enclosed Monitoring Well Sampling Log. Groundwater contours are represented on the enclosed Site Plan dated 7/11/22. 3.0 GROUNDWATER ANAYLTICAL RESULTS Groundwater analytical results were compared to the Massachusetts Drinking Water Standards (MDWS), published by MassDEP. These standards include Massachusetts Maximum Contaminant Levels (MMCLs), Secondary Maximum Contaminant Levels (SMCLs) and Office of Research and Standards Guideline (ORGS) concentrations. In addition, the results were compared to the MCP Method 1 Risk Characterization 3 Standards for the GW-1 (ingestion) and GW-3 (discharge to surface water) groundwater categories. A tabulation of the laboratory data for the November 2021 sampling event, along with a comparison to the above standards, is presented in Table 1: Results of Groundwater Analyses Compared to Various Standards. The results of semi-annual groundwater data over the past three (3) years are presented in Table 2: Temporal Groundwater Analysis Summary – November 2019 through May 2022. 3.1 Total Metals Groundwater samples collected from MW-1R, MW-3A, MW-4A, and MW-5 were analyzed for Total Arsenic, Barium, Cadmium, Chromium, Copper, Iron, Lead, Manganese, Mercury, Selenium, Silver, and Zinc. Monitoring wells MW-3B and MW-5B were sampled for Total Manganese and Total Arsenic only. Arsenic was reported above the Massachusetts Drinking Water Standard (0.01 mg/L) and the Method 1 GW-1 Risk Characterization Standard in monitoring well MW-1R (0.0397 mg/L). All other monitoring wells sampled reported Arsenic as Non-Detect. Release Notification was made to the DEP for the presence of similar concentrations of Arsenic in groundwater in 2008. In 2009, the Site was listed as Adequately Regulated under the MCP, wherein such localized impacts are confined to the property. Therefore, Release Notification to the MA DEP pursuant to 310 CMR 40.0315, is not required. Historically, similar concentrations of Arsenic, have been reported in monitoring wells MW-1 (May 2014) and MW-3A (May/November 2012). Arsenic has consistently been reported above the MA Drinking Water Standards and Method 1 GW-1 Standard in monitoring well MW-1R since November 2016, with concentrations ranging from 0.0175 mg/L to 0.058 mg/L. Arsenic was also reported above standards in MW-3A in November 2020 and November 2021 at concentrations of 0.0166 mg/l and 0.0124 mg/l, respectively. The elevated concentrations of Arsenic reported are attributed to various chemical processes mobilizing naturally-occurring Arsenic. These processes including reducing conditions in groundwater, elevated concentrations of organic carbon from previously-buried wood waste, and pH concentrations. Over the past few years, concentrations of Arsenic, and to a lesser extent Iron and Manganese appear to be cyclic in MW-1R and MW-3A, with higher concentrations reported in November and lower concentrations reported in May. These fluctuations may be related to the increased rainfall events in the fall, wherein higher amounts of these metals are leached to groundwater. Concentrations of Arsenic in downgradient monitoring wells MW-3B and MW-5B were reported as Non-Detect during the November 2021 sampling event. Future sampling events will continue to include MW-3B and MW-5B for Arsenic analysis. Total Iron was reported at concentrations exceeding Secondary Drinking Water Standards (SMCLs) in groundwater samples collected from MW-1R, MW-3A, and MW-5. The highest concentration of Total Iron was reported at MW-5 (83 mg/L). SMCLs are not health-based standards but were established to preserve the aesthetic qualities (i.e., odor and taste) of drinking water. In October 2013, the MassDEP adopted an Office of Research and Standards Guideline (ORSG) for Manganese based on a modified version of the US EPA Health Advisory for this element. The OSRG considers lifetime exposure (0.3 mg/L) and acute exposure (1.0 mg/L) for the general population, as well as a precautionary standard for acute exposure for children <1 year old (0.3 mg/L). Total Manganese was reported at concentrations exceeding the SMCL and OSRG in groundwater samples collected from all of the wells sampled, with the exception of MW-5B, where Manganese was reported above the SMCL, but below the OSRGs for chronic and acute exposures. Iron and 4 Manganese dissolve more readily in low oxygen environments and where the groundwater is slightly acidic. This is consistent with the field parameters measured during the May 2022 sampling event, wherein all wells exhibit Dissolved Oxygen concentrations below 1.0 mg/L, with the exception of MW-5B and MW-3B, where the two lowest concentrations of Manganese were reported. The tracking charts below show concentrations of Total Arsenic, Iron, and Manganese since May 2019. 0 0.01 0.02 0.03 0.04 0.05 0.06 0.07 mg / L Sampling Date Total Arsenic Concentrations in Seclected Wells - May 2019 through May 2022 MW-1R MW-4A MW-3A MW-5 0 10 20 30 40 50 60 70 80 90 mg / L Sampling Date Total Iron Concentrations in Selected Wells - May 2019 through May 2022 MW-1R MW-4A MW-3A MW-5 5 3.2 Volatile Organic Compounds (VOCs) Groundwater samples collected from monitoring wells MW-1R, MW-3A, MW-4A, and MW-5 were analyzed for VOCs via EPA Method 8260. Trace concentrations of Toluene, Acetone and 2-Butanone were reported in MW-1R below the MDWS and GW-1 Method 1 Standards. Trace concentrations of these compounds have been reported intermittently in MW-1 since 2019. There were no other VOCs reported in any of the wells sampled above the laboratory detection limits. 3.3 Poly-nuclear Aromatic Hydrocarbons (PAHs) Groundwater samples collected from monitoring wells MW-1R, MW-3A, MW-4A, and MW-5 were analyzed for PAHs. There were no PAHs reported in any of the wells sampled above the laboratory detection limits. Future sampling events will continue to monitor PAH concentrations at these wells. 3.4 Aggregate Organic Constituents Groundwater samples collected from monitoring wells MW-1R, MW-3A, MW-4A, and MW-5 were analyzed for Tannin & Lignin, Chemical Oxygen Demand (COD) and Total Organic Carbon (TOC). Tannin & Lignin concentrations ranged from 0.29 to 4.3 mg/L, with the highest concentration of Tannin & Lignin reported in MW-1R. The highest concentration of COD was also reported in MW-1R (140 mg/L) with lower concentrations reported in MW-5 (49 mg/L) and MW-3A (110 mg/L). COD was reported as Non-Detect in MW-4A. Concentrations of TOC were reported in all wells ranging from 41 mg/l to 0.85 mg/l, with the highest concentration reported in MW-1R (41 mg/L). The concentrations of Tannin & Lignin, COD and TOC reported are generally consistent with previous results reported in each well. There are no regulatory standards established for these parameters. Historical data for these parameters are presented in Table 2. 02468 101214 161820 mg / L Sampling Date Total Manganese Concentrations in Selected Wells - May 2019 through May 2022 MW-1R MW-4A MW-3A MW-5 6 3.5 Formaldehyde Groundwater samples collected from monitoring wells MW-1R, MW-3A, MW-4A, and MW-5 were analyzed for formaldehyde. No concentrations of formaldehyde were detected in any monitoring wells above the method detection limits. 3.6 General Chemistry Groundwater samples collected from MW-1R, MW-3A, MW-4A, and MW-5 were analyzed for general chemistry parameters including Alkalinity, Chloride, Total Cyanide, Sulfate, Sulfide and Total Dissolved Solids (TDS). Monitoring wells MW-3B and MW-5B were sampled for TDS only. Historic data for the general chemistry parameters is presented in Table 2.  The highest alkalinity value of 319 mg/L was reported at MW-1R. There are no regulatory standards for alkalinity.  Chloride was detected in all wells at concentrations between 9.6 mg/L and 150 mg/L. All of the wells reported Chloride below the SMCL of 250 mg/L. The highest chloride value was reported at monitoring well MW-3A (150 mg/L).  Total Cyanide was not detected in any well above the method detection limit of 0.005 mg/L. Sulfide was also not detected in any of the wells sampled.  Sulfate was reported as Non-Detect in monitoring wells MW-1R and MW-4A. Sulfate concentrations were reported in the remaining wells below the Secondary Maximum Contaminant Levels and consistent with historic data, as shown in Table 2.  TDS concentrations were reported at the SMCL in MW-1R (500 mg/L) and above the SMCL in MW- 3A (690 mg/L). TDS concentrations in monitoring wells MW-1R and MW-3A appear to be rebounding, after decreasing from the previous high concentrations in May 2020. TDS concentrations in downgradient wells MW-3B and MW-5B were both reported below 100 mg/L. Future groundwater testing will include TDS at the down gradient MW-3B and MW-5B locations while TDS concentrations remain elevated at upgradient locations. Groundwater samples collected from MW-1R, MW-3A, MW-4A, MW-5 were analyzed for Total Kjeldahl Nitrogen (TKN), Nitrate, Nitrite, Total Nitrogen and Total Phosphorus.  Nitrate was not reported in any well above the Drinking Water Standard of 10 mg/L. The highest concentration of Nitrate (5.41 mg/L) was reported in MW-4A. MW-3A reported concentrations of Nitrate at 4.06 mg/L, MW-1R reported concentrations at 0.159 mg/L, and MW-5 reported concentrations at 0.125 mg/L. Concentrations of Nitrate appear generally consistent with historical results and trends.  Nitrite was reported in monitoring wells MW-1R and MW-3A, at 0.094 mg/L and 0.059 mg/L, respectively. Monitoring wells MW-4A and MW-5 reported concentrations of Nitrite as Non-Detect.  TKN was reported as Non-Detect in monitoring well MW-4A. All concentrations of TKN were reported below the Drinking Water Standard of 10 mg/L, with the highest concentration detected in MW-3A (3.6 mg/L). 7  Total Nitrogen was reported in each of the wells sampled ranging from 3.0 mg/L in MW-1R to 7.6 mg/L in MW-3A.  Total Phosphorus was detected in each of the wells sampled, with concentrations ranging from 0.042 mg/L in MW-4A to 0.949 mg/L in MW-1R. There is no state or federal groundwater standard for Phosphorus. 3.7 Field Parameters Field parameters [temperature, pH, specific conductivity, dissolved oxygen (DO) and oxidation-reduction potential (ORP)] were recorded during the May 2022 groundwater sampling event. The historic data for the field parameters are presented on Table 2.  Groundwater temperatures varied between wells, ranging from 48.0 to 68.3 degrees Fahrenheit. Monitoring wells MW-1R, MW-3A, MW-4A and MW-5 exhibited groundwater temperatures between 48.0 to 68.3 degrees, with the highest temperature observed at MW-3A (68.3°F). Groundwater temperature at downgradient wells MW-3B and MW-5B were reported as 51.8° and 58.6°, respectively.  pH values in monitoring well MW-1R was within the range of Secondary Drinking Water Standards (6.5-8.5 S.U.). Monitoring wells MW-3A, MW-4A, and MW-5, were reported below the Secondary Drinking Water Standard (<6.5 S.U.). These values are typical of the slightly acidic groundwater conditions of Cape Cod and are consistent with historical data. pH values in monitoring wells MW- 3B and MW-5B were reported above Secondary Drinking Water Standard (>8.5 S.U.), although these concentrations are believed to be a result of faulty equipment rather than actual conditions.  Conductivity and DO concentrations varied from well to well with higher conductivity observed in MW-1R, MW-3A, and MW-5. Low DO (<1.0 mg/L) was observed in MW-1R, MW-3A, MW-4A, and MW-5, with higher concentrations noted at MW-3B (2.91 mg/L) and MW-5B (3.71 mg/L). 4.0 CONCLUSIONS The following is a summary of the key findings of the November 2021 groundwater monitoring event:  Total Arsenic was reported in MW-1R at 0.0397 mg/L, above the MA Drinking Water Standard (0.01 mg/L) and Method 1 GW-1 Risk Characterization Standard (0.01 mg/L). However, the Site is considered Adequately Regulated under the MCP, therefore no Notification to the MA DEP is required. The remaining wells, including downgradient wells MW-3B and MW-5B, reported arsenic concentrations as Non-Detect. Based on historical data, higher concentrations of metals and particularly arsenic are reported in November. The seasonal variations in concentrations may be due to fluctuations in groundwater levels and/or increased precipitation events. Concentrations of arsenic reported in MW-1R are attributed to various chemical processes mobilizing naturally- occurring Arsenic. These processes including reducing conditions in groundwater, elevated concentrations of organic carbon, and pH. Ongoing efforts to mitigate this issue include consolidating all wood waste in the area of Site Assignment and maintaining a 10’ separation to groundwater in areas where new wood waste is being deposited. Future sampling events will include sampling MW-3B and MW-5B for Arsenic analysis. • Various parameters (pH, Total Iron and Total Manganese) were reported at concentrations exceeding the SMCLs/OSRG parameters. These findings are consistent with results of historical data. The low pH reported is typical and inherent to the entire Cape Cod aquifer. At the request of the BWQRC, BEA will begin testing standing water in the ABC processing area to determine if concrete crushing may be contributing to rising pH levels at the site. The results of pH testing will be presented in the next semi-annual GW Monitoring Report. • Nitrate and Total Nitrogen were not detected at concentrations exceeding regulatory standards at any monitoring well during this sampling event. The low concentrations of Nitrogen compounds are a noted improvement in water quality since consolidation and recovery efforts were framed under the solid waste permitting of the facility. There were no PAH compounds detected, which is consistent with previous sampling events. This data continues to show no burial or influence of OHM materials. • Trace concentrations of Acetone, 2-Butanone (Methyl Ethyl Ketone), and Toluene were detected in MW -1R. No VOC compounds were detected in the remaining wells. Trace concentrations of these compounds have occasionally been reported in monitoring wells MW -1 (2015) MW -1R (2020, 2021) and MW -3A (2019). The concentrations reported are orders of magnitude below any standards. Future sampling events will continue to monitor VOCs to establish any emerging trends.

Serial_No:06232215:18 Page 3 of 88 MERCHANT/BS&R K10740A Project Name: Project Number: Lab Number: Report Date: L2227727 06/23/22 Case Narrative The samples were received in accordance with the Chain of Custody and no significant deviations were encountered during the preparation or analysis unless otherwise noted. Sample Receipt, Container Information, and the Chain of Custody are located at the back of the report. Results contained within this report relate only to the samples submitted under this Alpha Lab Number and meet NELAP requirements for all NELAP accredited parameters unless otherwise noted in the following narrative. The data presented in this report is organized by parameter (i.e. VOC, SVOC, etc.). Sample specific Quality Control data (i.e. Surrogate Spike Recovery) is reported at the end of the target analyte list for each individual sample, followed by the Laboratory Batch Quality Control at the end of each parameter. Tentatively Identified Compounds (TICs), if requested, are reported for compounds identified to be present and are not part of the method/program Target Compound List, even if only a subset of the TCL are being reported. If a sample was re-analyzed or re-extracted due to a required quality control corrective action and if both sets of data are reported, the Laboratory ID of the re-analysis or re-extraction is designated with an "R" or "RE", respectively. When multiple Batch Quality Control elements are reported (e.g. more than one LCS), the associated samples for each element are noted in the grey shaded header line of each data table. Any Laboratory Batch, Sample Specific % recovery or RPD value that is outside the listed Acceptance Criteria is bolded in the report. In reference to questions H (CAM) or 4 (RCP) when "NO" is checked, the performance criteria for CAM and RCP methods allow for some quality control failures to occur and still be within method compliance. In these instances, the specific failure is not narrated but noted in the associated QC Outlier Summary Report, located directly after the Case Narrative. QC information is also incorporated in the Data Usability Assessment table (Format 11) of our Data Merger tool, where it can be reviewed in conjunction with the sample result, associated regulatory criteria and any associated data usability implications. Soil/sediments, solids and tissues are reported on a dry weight basis unless otherwise noted. Definitions of all data qualifiers and acronyms used in this report are provided in the Glossary located at the back of the report. HOLD POLICY - For samples submitted on hold, Alpha's policy is to hold samples (with the exception of Air canisters) free of charge for 21 calendar days from the date the project is completed. After 21 calendar days, we will dispose of all samples submitted including those put on hold unless you have contacted your Alpha Project Manager and made arrangements for Alpha to continue to hold the samples. Air canisters will be disposed after 3 business days from the date the project is completed. Please contact Project Management at 800-624-9220 with any questions.

Associated results are considered to be biased high if the %D is negative and biased low if the %D is positive. A copy of the continuing calibration standard is included as an addendum to this report. Semivolatile Organics by SIM In reference to question H: L2227727-01: The surrogate recovery was outside the acceptance criteria for nitrobenzene-d5 (0%); however, re-extraction achieved similar results: nitrobenzene-d5 (3%). Since the re-extraction method blank was compromised, only the original extraction results are reported; all associated compounds are considered to have a potential bias. In reference to question I: All samples were analyzed for a subset of MCP analytes per client request.

Background In October 2019, the Town of Brewster Water Quality Review Committee conditionally approved subdivision plans for 1399 Freemans Way. One of the conditions required semi-annual groundwater monitoring for the first year, and annually thereafter. In addition, one round of soil gas monitoring was required. The first semi-annual groundwater and soil gas monitoring event was conducted on September 23, 2021. This report provides the results of the second semi-annual groundwater monitoring event conducted on April 29, 2022. Groundwater Assessment Location of Monitoring Wells Monitoring well ECE-1 is located in the northwestern portion of the property, well ECE-2 is located immediately east of the former non -potable well, and well ECE-3 is centrally located along the west side of Alexander Way, in a downgradient direction. Existing monitoring well MW -2 located in the south-central portion of the property and along the east side of Alexander Way. Figure 5 — Environmental Monitoring Locations illustrates the location of the groundwater monitoring wells. The groundwater monitoring wells were constructed to intercept the water table. Each well was constructed of a 2 -inch diameter, Schedule 40, threaded flush joint, PVC riser pipe and a .010 -inch slotted, 10 -foot long well screen installed. Well screens are located between 65 and 75 below ground surface. A five-foot long steel well protector is placed over the PVC well. 147 Bakerville Road S. Dartmouth, MA 02748 Tel: (508) 789-0089 Mr. Chris Dias May 16, 2022 Page 2 of 3 Groundwater Sample Collection and Analysis Groundwater samples were collected on April 29, 2022 from the four (4) monitoring wells. Prior to sample collection, the depth to water, total depth of the well, and volume of standing water were recorded, The depth to water measured on April 29, 2022 ranged between 65.04 and 66.03 feet below the groundwater surface (approximately 23 feet MSL) (Table 1). The regional groundwater flow direction is towards the east, Based on the groundwater elevations measured in April 2022, the site groundwater flow direction is relatively flat with a slight gradient to the east. For each sample event, the monitoring wells were purged of at least three well volumes prior to sample collection. Groundwater samples were collected by the EPA Low Flow purging and sampling procedures. Field measurements were made of the groundwater samples for pH, specific conductance, temperature and dissolved oxygen. These data are provided on Table 1. Groundwater samples collected from the four (4) monitoring wells on April 29, 2022 were analyzed for dissolved metal analysis: arsenic, antimony, barium, cadmium, chromium, copper, iron, lead, manganese, mercury, selenium, silver, zinc; and general chemistry compounds: Total Kjeldahl Nitrogen, Nitrite as N, Nitrate as N, and total nitrogen. Data Evaluation and Reporting The results of the groundwater analyses, as provided for on Table 2, is as follows: • Dissolved Metals Dissolved iron was detected in the groundwater samples from wells ECE-1, ECE-2 and ECE-3; the iron concentrations ranged between 147 and 15,200 ug/L. Lead was detected in the groundwater sample collected from well ECE-2 at a concentration of 2 ug/L. Manganese was detected in the groundwater samples from wells ECE-2 and ECE-3 at concentrations of 1,750 ug/L and 3,740 ug/L, respectively. Where applicable, the detected concentrations of dissolved metals were less than the Massachusetts Drinking Water Standards and the Massachusetts Contingency Plan (MCP) Groundwater Category GW-1 standards. Consistent with past data, dissolved metals were not detected in the groundwater sample collected from well MW -2. • General Chemistry The concentrations for the general chemistry parameters measured in the groundwater samples met Secondary Maximum Contaminant Levels (SMCLs) for Nitrate as N with concentrations ranging between <0.03 mg/L and 0.776 mg/L (SMCL is 10 mg/L); Nitrite as N was only detected (0.021 mg/L) in groundwater sample ECE-2 (SMCL is 1 mg/L); and Total Nitrogen with concentrations ranging between 0.650 mg/L and 2.89 mg/L (SMCL 147 Bakerville Road S. Dartmouth, MA 02748 Tel: (508) 789-0089 Mr. Chris Dias May 16, 2022 Page 2 of 3 is 10 mg/L). Total Kjeldahl Nitrogen levels ranged between 0.650 mg/L and 2.89 mg/L; there is no SMCL for Total Kjeldahl Nitrogen. The pH units measured in the groundwater samples ranged between 5.38 s.u. and 5.91 s.u.; these levels are lower than the SMCL pH range of 6.5 s.u. and 8.5 s.u. Conclusions The groundwater assessment of samples collected on April 29, 2022 from wells ECE-1, ECE-2, ECE-3 and MW -2, found that the concentrations of dissolved metals, where detected, were below the MCP RCGW-1 standards and the Massachusetts Drinking Water Standards and Guidelines.

These results are only representative of sample aliquots received at the laboratory. ESS Laboratory expects its clients to follow all regulatory sampling guidelines. Beginning with this page, the entire report has been paginated. This report should not be copied except in full without the approval of the laboratory. Samples will be disposed of thirty days after the final report has been delivered. If you have any questions or concerns, please feel free to call our Customer Service Department. Laurel Stoddard Laboratory Director REVIEWED By ESS Laboratory at 5:35 pm, May 09, 2022 Analytical Summary The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan, This plan utilizes the following methodologies: US EPA SW -846, US EPA Methods for Chemical Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized methodologies. The analyses with these noted observations are in conformance to the Quality Assurance Plan, In chromatographic analysis, manual integration is frequently used instead of automated integration because it produces more accurate results, The test results present in this report are in compliance with TNI and relative state standards, and/or client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes, Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal Standards. Any results which were found to be outside of the recommended ranges stated in our SOPs will be noted in the Project Narrative. 185 Frances Avenue, Cranston, RI 02910-2211 Tel: 401-461-7181 Fax: 401-461-4486 http://www.ESSLaboratoiy.com Dependability • Quality • Service Page 1 of 20 ESS Laboratory BAL Laboratory Division of Thielsch Engineering, Inc. The Microbiology Division of Thielsch Engineering, Inc, CERTIFICATE OF ANALYSIS Client Name: East Coast Engineering Client Project ID: Burning Grinder, Brewster, MA ESS Laboratory Work Order: 22D1172 SAMPLE RECEIPT The following samples were received on April 29, 2022 for the analyses specified on the enclosed Chain of Custody Record. To achieve CAM compliance for MCP data, ESS Laboratory has reviewed all QA/QC Requirements and Performance Standards listed in each method. Holding times and preservation have also been reviewed, All CAM requirements have been performed and achieved unless noted in the project narrative. Each method has been set-up in the laboratory to reach required MCP standards. The methods for aqueous VOA and Soil Methanol VOA have known limitations for certain analytes. The regulatory standards may not be achieved due to these limitations. In addition, for all methods, matrix interferences, dilutions, and %Solids may elevate method reporting limits above regulatory standards. ESS Laboratory can provide, upon request, a Limit Checker (regulatory standard comparison spreadsheet) electronic deliverable which will highlight these exceedances. Question I: All samples for Metals were analyzed for a subset of the required MCP list per the client's request.
