The purpose of the program is to monitor the quality of the groundwater downgradient of the leaching field of the FAST system, which treats wastewater from the restaurant. Also contained in this submittal is the mass balance nitrogen loading calculation prepared using the Cape Cod Commission method. Included in this report are the following: •Appendix A: As-built plans showing the approximate quarterly groundwater flow direction •Appendix B: Quarterly groundwater monitoring report forms •Appendix C: Groundwater test results summary •Appendix D: Tracking charts for key groundwater parameters •Appendix E: Laboratory test reports •Appendix F: Nitrogen Loading Calculation FAST System O&M Reports and Test Results GROUNDWATER FLOW Prior to quarterly sampling of the monitoring wells, each well was gauged using an electronic water level indicator to measure the depth, or distance to water from the top of the steel protective casing. An onsite benchmark was established using the rim of one of the manholes of the 5,000-gallon overflow tank. An assumed elevation of 20.00 was assigned to the benchmark. Using the benchmark, a level loop was conducted to establish the elevations at the top of the casing of each monitoring well. With these two pieces of information, namely the elevation at the top of casing (TOC) and the depth to water (DTW), the static water level (SWL) elevation with respect to the assumed elevation of the benchmark was established. This information is included on the summary table in Appendix C. The attached Groundwater Flow Direction Plans in Appendix A were prepared using the quarterly gauging results. The approximated groundwater contours for these plans were overlaid on the as-built plan, which was prepared by Down Cape Engineering, Inc., 5/20/97. The plans prepared in this way show the groundwater flow direction to be predominantly to the southwest. DEP Facility No.: MF143 C15667.00 2023 Annual Report GROUNDWATER SAMPLING An electric submersible purge pump was used to remove at least three volumes of water from each well prior to sampling. Dedicated bailers were then used to collect samples from the wells. The pH and specific conductivity samples for each well were tested onsite using portable test meters. The samples for laboratory analysis were picked up by a courier from the laboratory and transported to the laboratory for analysis. The results for each of the 2023 quarterly testing events are included on the attached Groundwater Monitoring Well Report Forms in Appendix B. All of the test results, for sampling conducted 2002-2023, are compiled and summarized on the table in Appendix C. The laboratory data sheets for the 2023 groundwater samples are included in Appendix E. The upgradient monitoring well, MW-2, consistently exhibited low concentration for all parameters tested. All of the wells tested below the laboratory reporting limit for BOD5. All wells tested below the reporting limit for all tested parameters. Nitrate-N concentrations were below Massachusetts Drinking Water Standards (10 mg/L) at all wells for each sample event. Total Nitrogen (NO2 + NO3 + TKN) mirrored the nitrate concentration, as nitrate was the major contributing compound. Appendix D shows graphically the concentrations of these key parameters at each well over the period 2002-2023. All of the downgradient wells are located close to the leaching field, so that the opportunity for dilution and dispersion of the effluent from the treatment system is limited. NITROGEN LOADING A mass balance nitrogen loading calculation was prepared using the Cape Cod Commission’s method, WRO Technical Bulletin 91-001. The area and recharge information was obtained from the initial nitrogen loading correlation calculations provided by Raggs, Inc. and Down Cape Engineering, Inc. The wastewater Total Nitrogen contribution was determined by averaging effluent Total Nitrogen test results provided by Wastewater Treatment Services, Inc (WTS). WTS is the wastewater operation and maintenance service provider for the treatment system and the test results are included in Appendix F. 2023 system sampling occurred on 03/20/2023, 06/22/2023, 09/07/2023, and once during the month of December 2023. Wastewater Treatment Services, Inc (WTS) indicated the results sampled in December 2023 would not be available until January 2023. For this reason, only 2023 system sample results from 03/20/2023, 06/22/2023, and 09/07/2023 are included in this annual report. Using the quarterly samples of 12/02/2022, 03/20/2023, 06/22/2023, and 09/07/2023 the system averaged a Total Nitrogen of 15.17 mg/L. Appendix F also includes copies of the operation and maintenance field reports prepared by Wastewater Treatment Services. The O&M inspections occurred on the dates of 03/20/2023, 06/22/2023, 09/07/2023, and once during the month of December 2023. The O&M inspection reports indicate the FAST system operated properly throughout the year. Please refer to the notes listed on the operation & maintenance forms located in Appendix F. DEP Facility No.: MF143 C15667.00 2023 Annual Report This year pumping was conducted by Robert B. Our Company. Please contact Robert B. Our for a list of their pumping records. The water usage at the site was provided by the Yarmouth Water Department. The total water usage, as recorded by the water supply meter was approximately 1,448,825 gallons for the 395-day period between August 1st, 2022 to August 31st, 2023. As indicated by the water department records and graph, the daily water usage averaged 3,668 gpd. It should be noted that these usage figures include water used for irrigation. Based on these input parameters, the nitrogen load calculates out to be 6.94 mg/L. The nitrogen loading calculation spreadsheet is included in Appendix F. The Mass Balance Correlation chart in Appendix F indicates that at a flow of 3,668 gpd, the average nitrogen concentration must be below approximately 9.65 mg/L in order to comply with the requirement to meet 5 mg/L at the property line. Based on the available information, the calculated nitrogen concentration, at 6.94 mg/L, shows that the performance of the wastewater treatment system has been sufficient in meeting this condition. Quarterly system samples from 12/02/2022, 03/20/2023, 06/22/2023, and 09/07/2023 were used for this calculation. Sampling of the monitoring wells at this site will continue on a quarterly basis. The next sample event will be conducted in March 2024. The 2024 Annual Report will be prepared and submitted following the completion of sampling in December 2024. Please do not hesitate to contact us if you have any questions regarding the information contained in this report. Very truly yours, COASTAL ENGINEERING CO., INC. Chad A.
