Figure 1-2 shows the approximate location of waste placement during the third quarter 2007 monitoring period. The following types of waste were received: Non-hazardous solid waste—319,552 tons Asbestos—788 tons Sewage and wastewater treatment sludge—8,228 tons 1.5 LANDFILL GAS MONITORING During the third quarter 2007 no perimeter soil-pore gas probes exceeding the regulatory limit of 5 percent, suggesting an improvement in landfill gas at the site. In accordance with California Code of Regulations Title 27, Section 20937,Forward continues to install additional landfill gas extraction wells(as needed), and makes regular adjustments to the landfill gas extraction system to optimize efficiency of the landfill gas extraction system. Furthermore, in accordance with CCR Title 27, Section 20937(x)(1),methane monitors are installed in all buildings at the site to protect public health and safety and the environment. During the third quarter 2007, no methane was detected in any of the facilities buildings. A copy of the landfill gas monitoring probe data is provided in Appendix A. 2.0 FORWARD UNIT 2.1 WATER QUALITY MONITORING 2.1.1 Sampling and Laboratory Analyses During the third quarter 2007, depth-to-water measurements were recorded in all wells on August 13, 2007, and the groundwater monitoring wells were sampled by ATC Associates (ATC)between August 13 and 16, 2007. Surface water stations were sampled on August 15, 2007. Of note,well MW-23R was not sampled this quarter because there was insufficient water in the well to collect a sample as a result of active pumping from an adjacent agriculture well at the time of sampling. All lysimeters were inspected and a vacuum was set on August 17, 2007. The lysimeters were checked for soil-pore liquid on September 12, 2007, and sufficient soil-pore liquid was present to collect samples from lysimeters E-2,W-2, LY-A, and LY-BG1. Of note, lysimeter D-01 has been buried and Forward is working to locate the lysimeter. A single sample set was collected from each point containing sufficient liquid and submitted to BC Laboratories, Inc.
