1,0 INTRODUCTION
<br /> On behalf of Forward Inc. (Forward),this report presents water quality monitoring data
<br /> generated during the second quarter 2007 monitoring period for the Forward Landfill in
<br /> San Joaquin County, California. Monitoring was performed in accordance with
<br /> requirements listed in the Central Valley Regional Water Quality Control Board
<br /> (RWQCB) Order No. R5-2003-0049. For reporting purposes the water quality
<br /> monitoring network consists of two units: the Forward Unit and the Austin Unit. Section
<br /> 1 provides a description of the monitoring network, site inspections, and standard
<br /> observations; Sections 2 and 3 include discussions of water quality data for the Forward
<br /> and Austin Units,respectively.
<br /> 1.1 MONITORING NETWORK
<br /> The water quality monitoring network at the Forward Unit currently includes 19
<br /> groundwater monitoring wells,one domestic well,two surface water monitoring stations,
<br /> and 17 lysimeters(Figure 1-1). Monitoring wells at the Forward Unit have been
<br /> constructed to monitor groundwater at the facility as follows:

<br /> The monitoring network at the Austin Unit currently includes 16 groundwater monitoring
<br /> wells and two surface water monitoring stations (Figure 1-1). Of note,well AMW-3,
<br /> located in a portion of the landfill expansion area, was abandoned in April 2007, and well
<br /> AMW-5,which has an inoperable pump stuck in the well is scheduled to be abandoned in
<br /> August 2007. Well AMW-5R was constructed in May 2007 as a replacement to well
<br /> AMW-5 and will be added to the monitoring program during the third quarter 2007. The
<br /> detection monitoring program(DMP)wells are used to detect a potential release from the
<br /> landfill,while the corrective action program (CAP)wells are used to evaluate changes in
<br /> water quality caused by releases from the landfill and by subsequent corrective action
<br /> measures. Monitoring points at the Austin Unit have been constructed to monitor the
<br /> groundwater/surface water at the facility as follows:
