Water Quality Monitoring Report Forward Landfill WDR Order No. R5-2003-0049 was formally adopted by the RWQCB on March 14, 2003, which combined the former Austin Road and Forward Landfills into one landfill, now known as the Forward Landfill. In response to the detection of volatile organic compounds (VOCs) in groundwater downgradient of the Austin Unit, the RWQCB issued a Cleanup and Abatement Order (CAO) on December 8, 2008. Under the CAO, Forward has installed 24 additional groundwater monitoring wells (five of which were later abandoned) to help define the vertical and lateral extent of VOCs in groundwater downgradient of the Austin Unit. WDRs were updated and WDR Order No. 115-2014-0006 was formally adopted by the RWQCB on February 6, 2014. In response to continued detection of VOCs in groundwater downgradient of the Austin Unit, the RWQCB issued CAO Order No. R5-2017-0703 on April 10, 2017. Under the CAO, Forward has submitted multiple workplans for landfill gas and domestic well monitoring, and construction of additional groundwater monitoring wells and groundwater extractions wells to address VOCs in groundwater downgradient of the Austin Unit. 1.3 Standard Observations In accordance with Monitoring and Reporting Program (M&RP) Order No. 115-2014-0006, Section A.6.d, Forward personnel conducts Standard Observations for the landfill units, along the perimeter of the landfill units, and for receiving waters. As provided in Appendix A, these observations include identification of evidence of liquids entering or leaving the landfill, indications of ponding on the landfill or erosion of the landfill cover soils, and identification of strong landfill gas odors. No unusual conditions were identified by Forward personnel during the third quarter 2017 monitoring period. In addition to Forward's inspections,the San Joaquin County Environmental Health Department (CEHD) performed monthly inspections at the facility on July 21, August 8, and September 15, 2017. In addition, CalRecycle conducted an 18-month inspection in conjunction with the CEHD on August 8, 2017. No Notices of Violation (NOVs) were issued by the CEHD or CalRecycle during the monitoring period. Completed inspection forms are presented in Appendix A. Pursuant to the Forward Landfill Odor Control Management Plan (Forward, 2009), the Forward Operations Manager performs weekly monitoring for odors on the landfill surface and along the perimeter of the landfill. In the event that an odor complaint is made by the public, Forward performs an immediate investigation to identify the source of the odor. Following confirmation of an odor, mitigation measures are implemented. Project No.5017.1030 I Water Quality Monitoring Report 3 October 2017
