WORTH COUNTY – SR 112 SLYVESTER PHASE 1 LANDFILL
PROPOSAL DUE DATE: Tuesday October 17, 2017 @ 5:00 p.m.
This Request for Proposal presents the environmental monitoring requirements including groundwater and surface water sampling and analysis, and methane monitoring for the Worth County – SR 112 Sylvester Phase Sanitary Landfill. The work includes professional geotechnical engineering or geological services necessary to comply with the Rules of the Georgia Department of Natural Resources, Environmental Protection Division (EPD) Chapter 391-3-4-14, “Groundwater Monitoring and Corrective Action”, and Chapter 391-3-4-.07 “Groundwater and Surface Water Monitoring Plan”, “Explosive Gases Control” and all currently applicable guidance.
SCOPE OF WORK:
The Worth County – SR 112 Sylvester Phase Sanitary Landfill [Permit No. 159-004D(SL)] is an unlined landfill that commenced operation in 1978 and terminated operation in 1997. The site is subject to the Detection and Assessment Monitoring programs under Subtitle D and Rules of Georgia Department of Natural Resources Environmental Protection Division Chapter 391-3-4-14 and Chapter 391-3-4-.07. A schedule to delineate contaminant extents is being developed and implemented by others.
The Detection Monitoring Event shall include sampling and analysis of ten (10) groundwater monitoring wells and one (1) field blank for Appendix I Volatile Organic Compounds (VOC) and Metals. In addition, one (1) of these wells will also be analyzed for Mercury and one (1) other well will also be analyzed for Endosulfan I. An upstream and downstream surface water sample from the adjacent creek and the discharge of one (1) storm water pond will be analyzed for the surface water constituents including (metals, Chlorides, Cyanide, Total Organic Carbon and Chemical Oxygen Demand). Field Measurements will be required for all water samples.
The Assessment Monitoring Event shall include sampling and analysis of four (4) wells for the complete list of Appendix II constituents. The remaining six (6) groundwater monitoring wells and one field blank will be sampled and analyzed for the Appendix I VOC and Metals. An upstream and downstream surface water sample from the adjacent creek and the discharge of one (1) storm water pond will be analyzed for the surface water constituents including (metals, Chlorides, Cyanide, Total Organic Carbon and Chemical Oxygen Demand). Field Measurements will be required for all water samples.
In addition the proposer should recommend a sampling and/or monitoring strategy for addressing landfill gas impacts to groundwater at two locations (GWA-1 and GWC-2) which have documented impacts by volatile constituents. This strategy should be discussed in the Proposal Narrative section and the cost for these sampling and/or monitoring costs should be included in the Proposal Cost Tabulation sheet under “other”.
Reporting for both events should include development of a potentiometric surface map for the uppermost aquifer at the site based on water levels obtained on the same day, in order to meet the performance criteria in the solid waste rules.
Field parameters including; pH, Temperature, Specific Conductance and Turbidity, at a minimum, should be recorded after each well volume is purged and at the time of the sample collection. A minimum of three (3) well volumes should be purged from each well (unless a well purges dry) and stabilized conditions must be documented as required by applicable guidance (i.e.; US EPA SESDPROC-301). If the metals samples are collected at a later time and/or date than the VOC samples Turbidity must be recorded at time of metals sample collection. In no case will the metals sample be obtained greater than 24 hours after the VOC sample.
The report or attachment should include copies of all original logs or data sheets used to record field measurements, complete groundwater and surface water analytical results, and complete presentations of the statistical evaluation input and results. The reporting and management of the analytical data must be in a form (i.e.; compiled in tables and/or spreadsheets) that enables efficient use for any subsequent evaluations that may be required for: delineation of horizontal and vertical contaminant migration; landfill gas impacts to groundwater; potential alternative source identification; and physical, biological and geochemical indicators of groundwater impacts. Statistical analysis should, if necessary, address false positives produced by any data, statistical database or statistical evaluation method anomalies, as deemed necessary by the qualified groundwater scientist. Groundwater reports must be submitted to the Countywithin 90 daysof completion of field monitoring. Groundwater monitoring cost payments will be based on only the analyses performed; dry water sampling points will not count towards payment.
Quarterly methane gas monitoring is required at the facility and includes eleven (11) monitoring wells, eight (8) bar hole punches, ten (10) passive vents and two (2) ambient air monitoring locations. Methane monitoring reports should be submitted to the County within 7 days so that County can review the reports and submit them to EPDwithin 14 daysof the monitoring.
GENERAL REQUIREMENTS
All sampling and reporting is to be complete and performed in accordance with all state and federal standards, including Georgia Department of Natural Resources, Environmental Protection Division (EPD) Chapter 391-3-4-.14, “Groundwater Monitoring and Corrective Action”, and Chapter 391-3-4-.07 “Groundwater and Surface water Monitoring Plan”, “Explosive Gases Control” and all currently applicable state and federal guidance and in accordance with the facility’s approved Design and Operation Plan and Closure and Post Closure Care Plan.
The successful proposer will be expected to be knowledgeable of all applicable requirements and to advise the County if additional sampling and analysis are needed to address characterization of any potential releases or resolution of anomalous results. In addition, the successful proposer will be expected to perform appropriate statistical analysis to determine if groundwater quality data represent a statistically significant deviation from background. The successful proposer will also be expected to make interpretations of the data and make supportable judgments and recommendations as to appropriate actions that could assist the county in meeting the performance objective of maintaining compliance with respect to the groundwater, surface water and landfill gas monitoring programs.
The County will only pay for those wells or points from which a sample is collected, analyzed, and accepted by EPD. Should a sample be rejected by EPD for any reason, it will be the responsibility of the contractor to bear all cost to resample, analyze, and report the results to EPD.
The successful proposer must prepare a report documenting each sampling event that includes at minimum a potentiometric surface map sealed by a geotechnical engineer or geologist licensed to practice in the State of Georgia (PE or PG), with demonstrated qualifications in groundwater hydrology, calculated groundwater flow rate and direction, surface water graphs (or other acceptable surface water data evaluations) for evaluating if landfill impacts are occurring (as per the EPD guidance), a statistical analysis report updated to include the historical and recent data collected for each report, Appendix II constituent analysis (biannually), summary tables, copies of the laboratory certificates of analysis, and a discussion describing the sampling event, any sampling issues, omission or problems, and recommendations, if applicable. The report should include a certification statement (in accordance with EPD requirements) signed and sealed by a professional geotechnical engineer or geologist licensed to practice in the State of Georgia.
For groundwater, surface water and methane monitoring, the successful proposer shall provide a draft report to Worth County’s engineering consultant for review and comment. The successful proposer must revise each report as necessary to address the consultant’s comments and provide two (2) copies of the final report to the County, one (1) copy to the appropriate EPD office and an electronic PDF document of the final report to the County’s consultant.
