HomeMy WebLinkAbout09003_Florence Mill_Forest City Monitoring Rpt_20230515 Memorandum AECOM Technical Services of North Carolina, Inc. is pleased to provide the attached Semi-Annual Soil Gas Sampling and Annual Groundwater Monitoring Report for the Florence Mill Brownfield Project Site (the Site) located at 186 Mill Street, Forest City, North Carolina. In 2019, construction was completed at the Site which was turned into a public outdoor space known as the Forest City Pavilion on Park Square (POPS). The results herein include data from the semi-annual soil vapor monitoring, and annual groundwater monitoring events in accordance with the objectives defined in the approved scope of work originally proposed in the environmental Management Plan (EMP) by Irminger Consulting Inc (IC), dated December 2, 2013 and further established in the Brownfield Agreement (BA) for the project. As documented in the Construction Completion and Monitoring Point Installation Memorandum, dated May 24, 2019, ten soil gas vapor points (VP-1 to VP-10) were installed around the Site for monitoring of soil gas at depths 5.5 ft below ground surface (bgs), and 20 ft bgs, respectively. Initial sampling of these vapor points was completed in February 2019 along with sampling of monitoring wells MW-1R and MW- 17. Consistent with the BA, the soil vapor points were sampled in February 2023. Report Objectives:  Summarize the groundwater and soil vapor monitoring completed in February 2023.  Present analytical results for groundwater and soil vapor samples. Monitoring Well Sampling Methods Monitoring wells MW-1R and MW-17 were sampled with pre-deployed HydraSleeve sampling bags on February 21, 2023. Water quality parameters of temperature, pH, specific conductance, dissolved oxygen, and oxygen reduction potential (ORP) were measured and recorded using a YSI Pro Plus portable field instrument. Groundwater samples were collected in pre-preserved, laboratory provided containers and were immediately placed on ice. The groundwater field-measured water quality data are included in the field notes in Attachment A. The laboratory analytical reports for the groundwater samples are presented in Attachment B and a Photo Log from the sampling event is included as Attachment C. Groundwater samples were transported to Pace Analytical Services – Charlotte in North Carolina under chain of custody for analysis of VOCs by USEPA Method 8260D. Results for the February groundwater Date: Monday, May 15, 2023 To: Sarah Hardison (NCDEQ Brownfields) CC: Janet Mason and Amy Bridgers (Town of Forest City) From: Cristin Dolan and Conan Fitzgerald (AECOM) Subject: Florence Mill Brownfield Project Semi-Annual Soil Gas Sampling and Annual Groundwater Monitoring – February 2023 sampling data are presented in Table 1 and historic results are presented on Table 2. The only exceedance of the North Carolina 15A NCAC 02L (2L) groundwater standards was for perchloroethylene (PCE). Results were consistent with historical ranges. Soil Vapor Sampling Methods On February 21, 2023, soil gas samples were collected from nine of the ten site soil vapor monitoring points. During the site activities, VP-5 was noted to contain water which prevented sample collection. Vapor Points VP-1 to VP-4, and VP-6 to VP-10 were sampled using 6-liter Summa canisters fitted with 0.5-hour flow controllers. Prior to sampling, helium leak tests were performed at each soil vapor location to verify a proper seal between the permanently installed stainless steel vapor implants and the ground surface. Reference Attachment A for field notes and parameters recorded during vapor sampling and leak testing. Samples were submitted to a certified laboratory for analysis of volatile organic compounds (VOCs) by United States Environmental Protection Agency (EPA) Method TO-15-full analyte list. The laboratory analytical reports for the soil vapor monitoring points are presented in Attachment B. A Photo Log from the sampling event is included as Attachment C. Samples were collected in accordance with the AECOM sampling protocols (Attachment D). Soil Gas Analytical Results Results for February soil vapor sampling data are presented in Table 3. Results for tetrachloroethene (PCE) and trichloroethylene (TCE) are summarized on Figure 1 for 2021 through 2023. For data completeness, a summary of all historical soil gas analytical results for the since February 2019 can be found in Table 4. The following VOCs were detected above their corresponding NC DEQ Non- Residential Vapor Intrusion Screening levels for the February 2023 monitoring event.  PCE and TCE were the only analytes detected above NC DEQ Non-Residential Vapor Intrusion Screen Levels of 3,500, and 180 µg/m³, respectively.  PCE was detected above its respected NC DEQ Non-Residential Vapor Intrusion Screening Levels in four vapor monitoring points (VP-1 to VP-4) during the February 2023 sampling. Highest PCE values were detected in VP-4 at 6,710,000 µg/m³ during the February 2023 sampling. TCE was detected above its Residential Screening criteria in VP-3 and VP-4, with the greatest detection in VP-4 of 6860 µg/m³.  Vapor points VP-1 through VP-4 were installed in the vicinity of the former drycleaner, so the presence of elevated PCE concentrations in this location are not unexpected. The structure in this area currently houses a concession stand and bathrooms, and thus is used very intermittently. Indoor air sampling conducted in March 2021 confirmed that passive vapor mitigation features installed within the structure is mitigating exposure for those using the facility.  Generally, the deeper screened nested monitoring points (19-20 ft bgs) exhibited significantly higher PCE concentrations than the adjacent shallow screened (4.5-5.5 ft bgs) monitoring points in this area. This continues to suggest that groundwater is the source of chlorinated vapors in this area. Next Monitoring Event Per the BA, the next monitoring event is scheduled to occur in August of 2023 and will include soil vapor data collection only. Tables Table 1.

The laboratory analyzed these samples within the recommended analytical holding time and performed dilutions appropriately and correctly. For all results, the data of interest appear to be generally acceptable. Sincerely, Hannah Lucas Project Name: Florence Mill Date: March 2023 Page No.: 2 2 DATA VALIDATION REPORT INTRODUCTION During February of 2023, groundwater samples from two locations were collected from the Florence Brownfield site. The samples were forwarded under chain of custody to Pace Analytical Services in Huntsville, NC for analysis of a site-specific set of volatile organic compounds (VOC). The samples were received under chain of custody, intact, and in good condition. In accordance with the provisions of the approved work plan, one hundred percent of the data were validated to a Stage 2A level. This report is applicable to the field sample data from the following locations: Pace SDG Sample ID Pace Lab Sample ID 8260D 9265372 MW-1R 92653572001 X MW-17 92653572002 X The analytical procedures employed in the course of the analyses are taken from United States Environmental Protection Agency (USEPA) (USEPA) SW-846, Test Methods for Evaluating Solid Wastes. The correct and current methods as specified in the work plan were used by the laboratory. . The data were validated using USEPA National Functional Guidelines for Organic Superfund Data Review (November 2020, EPA 540-R-20-005). These were applied to the methods of analysis such that the specifications of the methods take precedence over the specifications of the validation protocol in those instances where the specifications differ. The analytical data packages and the data validation notes are on file at AECOM’s Raleigh, North Carolina office and are available for review upon request. In the sections that follow, the findings of the validation effort are presented. Each review begins with a listing of the validation parameters assessed. An asterisk before any individual item indicates that the data were determined to be acceptable in that area of review or that element was not discussed further in the report. Specifically, the data are deemed to be acceptable if (1) all technical criteria were met, or (2) any observed failures have no impact on data quality and no data qualification is indicated. Data qualifiers would be applied to the data to indicate that some of the data may be considered estimated values, the result of background contamination, or unusable. The flags used in the report are defined at the end of the report.

Holding Times The method holding time for 8260D is 14 days from sample collection, samples were analyzed within analytical holding time: Sample Date Collected Date Analyzed Days MW-1R 02/21/2023 12:15 02/23/2023 14:21 2 MW-17 02/21/2023 11:12 02/23/2023 23:38 2 2. Method Blanks The method blanks associated with samples were below reporting limit. 3. Laboratory Control Spike/Laboratory Control Spike Duplicate (LCS/LCSD) The LCS/LCSD recoveries for all samples were within the laboratory control limits. 4. Matrix Spike/Matrix Spike Duplicate (MS/MSD) The MS and MSD performed on field sample MW-1R displayed percent recoveries less than the lower quality control limit for all analytes due to sample dilution. Therefore, qualification of data is unwarranted. 5. Surrogate Recovery Surrogate recovery for all samples was within the method requirement of 70-130% recovery. 6. Sample Dilutions Samples were analyzed at a standard dilution of approximately 1x and were analyzed at higher dilutions due to high concentrations: Sample Dilution concentration (µg/L) MW-1R 10 Tetrachloroethene (1,600) These dilutions were performed appropriately and correctly. #=CL# February 27, 2023 LIMS USE: FR - CONAN FITZGERALD LIMS OBJECT ID: 92653572 92653572 Project: Pace Project No.: RE: Conan Fitzgerald AECOM 5438 Wade Park Blvd Suite 200 Raleigh, NC 27607 FLORENCE MILL BROWNFIELD-FORES Dear Conan Fitzgerald: Enclosed are the analytical results for sample(s) received by the laboratory on February 22, 2023.

ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean-Up U - Indicates the compound was analyzed for, but not detected. Acid preservation may not be appropriate for 2 Chloroethylvinyl ether. A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPAMethod 8260. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Reported results are not rounded until the final step prior to reporting.

The laboratory analyzed these samples within the recommended analytical holding time and performed dilutions appropriately and correctly. For all results, the data of interest appear to be generally acceptable. Sincerely, Hannah Lucas Project Name: Florence Mill Date: March 2023 Page No.: 2 2 DATA VALIDATION REPORT INTRODUCTION During February of 2023, air samples from nine locations were collected from the Florence Brownfield site. The samples were forwarded under chain of custody to Pace Analytical Services in Huntsville, NC for analysis of a site-specific set of volatile organic compounds under Compendium Method TO-15. The samples were received under chain of custody, intact, and in good condition. In accordance with the provisions of the approved work plan, one hundred percent of the data were validated to a Stage 2A level. This report is applicable to the field sample data from the following locations: Pace SDG Sample ID Pace Lab Sample ID TO-15 92653832 VP-1 9265383201 X VP-2 9265383202 X VP-3 9265383203 X VP-4 9265383204 X VP-6 9265383205 X VP-7 9265383206 X VP-8 9265383207 X VP-9 9265383208 X VP-10 9265383209 X The analytical procedures employed in the course of the analyses are taken from United States Environmental Protection Agency (USEPA) Ambient Monitoring Technology Information Center (AMTIC) Compendium of Methods for the Determination of Toxic Organic Compounds in Ambient Air. The data were validated using USEPA National Functional Guidelines for Organic Superfund Data Review (November 2020, EPA 540-R-20-005). These were applied to the methods of analysis such that the specifications of the methods take precedence over the specifications of the validation protocol in those instances where the specifications differ. The analytical data packages and the data validation notes are on file at AECOM’s Raleigh, North Carolina office and are available for review upon request. In the sections that follow, the findings of the validation effort are presented. Each review begins with a listing of the validation parameters assessed. An asterisk before any individual item indicates that the data were determined to be acceptable in that area of review or that element was not discussed further in the report. Specifically, the data are deemed to be acceptable if (1) all technical criteria were met, or (2) any observed failures have no impact on data quality and no data qualification is indicated. Data qualifiers would be applied to the data to indicate that some of the data may be considered estimated values, the result of background contamination, or unusable. The flags used in the report are defined at the end of the report.

Attachment D AECOM Soil Gas and Air Sampling Procedures (Rev1) March 13, 2018 AECOM – North Carolina Standard Operating Procedures 1. Purpose and Scope Standard operating procedure for the collection of soil gas samples using laboratory provided Summa canisters. 2. Procedure 2.1 Required Equipment: • Project Health and Safety Plan (HASP) • Work Plan • Summa Canister with a Flow Regulator from a certified laboratory (precalibrated for an 0.5 hour interval) • Field forms – Summa Canister Field Sampling Data Sheet • ¼” Stainless steel nuts and ferrules • AMS Probe Kit or Hand Auger • 1/4" OD x 1/8" ID Teflon tubing • #2 driller sand • Hydraulic cement or bentonite • Water • Ziplock bags • Helium detector • Helium • Hand Vacuum Pump or Gilian GilAir Pump • Tedlar bags • Safety Cones • Laminated Sign to notify Air Sampling in progress • Chain of Custody (COC) • FedEx forms • Standard wrench set • Digital camera 2.2 AMS Soil Gas Sampling Method 1. Prior to sampling, locate any underground utilities to insure the safety of subsurface work conditions. 2. Use a 1½ inch stainless steel concrete bit and rotary hammer drill to core an entrance into the concrete or asphalt slab if needed. 3. Attach Teflon tubing to the barb tang of the retractable stainless steel screened soil gas vapor sampling tip. 4. Cut the tubing to the desired length so you can feed it through extra extension rods. 5. Attach the Retractable stainless steel screened soil gas vapor sampling tip to the extension rod. Place the extension drive adaptor to the opposite end of extension rod to protect threads when using the rotary hammer drill. (Rev1) March 13, 2018 6. Place the tip and the extension rod into the cored out hole and place the hammer drill in line with the extension drive adaptor. 7. Using the hammer drill, drive the tip and extension rod into the ground and add extension rods as needed to the desired depth beneath the ground surface. Fully tighten rods together to protect threads. 8. Using the jack supplied in the kit, jack out the extension rod a couple of inches to release the screen. 9. With the screen released, use a hand held vacuum pump to purge the subsurface air through the Teflon tubing. 10. After the soil gas vapor sampler is purged, connect the stainless steel summa canister to the Teflon tubing using air tight stainless steel fittings. Utilize the laboratory supplied flow controller to pull the sample over the desired time interval. 11. To remove the retractable stainless steel vapor sampling tip, use the jack supplied in the kit. Connect it under the extension drive adaptor and continue to jack the tip out of the ground fully. 12. Dissassemble the stainless steel vapor sampling tip. 13. Remove the Teflon tubing from the barb tang at the top of tip and dispose of the tubing. 14. Decontaminate the tip with soap that does not affect environmental parameters (Liquinox) and use a soft-bristle brush to wash away all dirt from the extensions and tip parts. Rinse with clean fresh water and let air dry. 2.3 Permanent Soil Gas Vapor Sampler: 1. Permanent sampling tips can also be installed using the same method as described above. However, a different sampling tip is installed. 2. The tip shown above is a permanent tip that can be used for multiple vapor monitoring events. The design is the same but uses a Teflon umbrella to seal the screen into place. (Bentonite can also be placed in the hole above the screen to provide a tighter seal for a longer period of time). 3. Sampling from the permanent tips can be performed using the method described above. (Rev1) March 13, 2018 2.4 AMS Vapor Implants Sampling Method 1. Prior to sampling, locate any underground utilities to insure the safety of subsurface work conditions. 2. Use a clean, stainless steel hand auger to auger down to the desired depth of soil gas vapor sampling beneath the ground surface. Note: Vapor implant should not be placed in saturated soils. 3. Attach Teflon tubing to the barbed tang of a 6” AMS Vapor Implant (AMS Item #21010). Make sure that the connection between the barbed end of the implant and the Teflon tubing is secure. 4. Lower the AMS Vapor Implant and attached tubing into the borehole until the Implant reaches the desired depth. The top of the vapor implant should be a minimum of five feet below ground surface. 5. Cut the tubing to the desired length so that you have approximately 2’ of extra tubing to attach to the summa canister. 6. Using #2A filter sand, add enough sand to cover the 6” Implant and 2-3” above the Implant. Check the depth of sand using a measuring tape. 7. Add 10-12” of hydraulic cement or bentonite to the top of the sand to create a seal. Check the depth of sand using a measuring tape. If using bentonite, hydrate the bentonite to ensure a proper seal. Wait 2 hours or until the hydraulic cement has fully hardened, whichever is longer. 8. Use a hand held vacuum pump to purge the subsurface air through the Teflon tubing. Purge a minimum of one pore volume of the borehole. The pore volume should be a minimum of the volume of the tubing and sand filter pack. Calculate pore volume using formula: v = π ra2La + π rt2Lt where: v = Volume La = Length of sand-filled annular space, and ra = Radius of annular space Lt = Length of tubing, and rt = Radius of tubing 9. Thread the tubing through the helium leak test device (helium chamber). 10. Attach the helium detector to the helium leak test device. Attach the helium container to the leak test device using teflon tubing and fill the leak test device with helium until the helium detector reads >50%. 11. Use the hand pump to fill a 1 Liter tedlar bag with air from the sample port. 12. Close the tedlar bag and detach it from the pump. 13. Turn off the flow of helium into the helium leak test device. 14. Remove the helium detector from the leak test device and allow the helium detector reading to reach 0 ppm. 15. Insert the helium detector into the silicon tubing attached to the tedlar bag and open valve on the bag. 16. Record the reading. If the reading is below 10% of the value measured within the test device, proceed to the next step. If the reading is above 10%, repeat the leak test and reconstruct the sample point as necessary. (Rev1) March 13, 2018 17. Be sure that the valve to the tedlar bag is open and that nothing is blocking the flow to the helium detector. The detector may produce false readings if the detector pump is strained or if methane is present in the soil gas. 18. After the helium test has been satisfactorily completed and soil gas vapor sampler is purged, connect the stainless steel summa canister to the Teflon tubing using air tight stainless steel fittings. Utilize the laboratory supplied flow controller to pull the sample over the desired time interval. 19. To remove the stainless steel Implant, break up the hydraulic seal. Tug gently on the Teflon tubing until the Implant is freed. 20. Remove the Teflon tubing from the barb and dispose of the tubing and the disposable stainless steel Implant. 21. Backfill borehole. 3.
