1.0 INTRODUCTION
<br /> On behalf of Forward Inc. (Forward), this report presents water quality monitoring data
<br /> generated during the second quarter 2008 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 and also included analyses of the constituents of
<br /> concern(COCs)that were identified in Order No. R5-2003-0049, which are completed
<br /> every 5 years during alternate Spring and Fall monitoring events. For reporting purposes
<br /> the water quality monitoring network consists of two units: the Forward Unit and the
<br /> Austin Unit. Section 1 provides a description of the monitoring network, site inspections,
<br /> and standard observations; Sections 2 and 3 include discussions of water quality data for
<br /> the Forward and Austin Units,respectively.
<br /> 1.1 MONITORING NETWORK
<br /> The water quality monitoring network at the Forward Unit currently includes 15
<br /> groundwater monitoring wells (five of which are dual depth well pairs), one domestic
<br /> well, two surface water monitoring stations, and 171ysimeters (Figure 1-1). Well
<br /> MW-24 was recently constructed in anticipation of the proposed southwesterly expansion
<br /> of the landfill. Monitoring wells at the Forward Unit have been constructed to monitor
<br /> groundwater at the facility as follows:

<br /> The monitoring network at the Austin Unit currently includes 14 groundwater monitoring
<br /> wells, two domestic wells, and two surface water monitoring stations (Figure 1-1). Of
<br /> note, wells AMW-5R and AMW-19BR were recently constructed as replacements to
<br /> wells AMW-5 and AMW-19B which were recently abandoned to facilitate landfill
<br /> expansion. These new wells will be surveyed during the third quarter 2008. 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:
