1,0 INTRODUCTION
<br /> On behalf of Forward Inc. (Forward), this report presents water quality monitoring data
<br /> generated during the first quarter 2009 monitoring period for the Forward Landfill in San
<br /> Joaquin County, California. Monitoring was performed in accordance with requirements
<br /> listed in the Central Valley Regional Water Quality Control Board (RWQCB) Order No.
<br /> R5-2003-0049. For reporting purposes the water quality monitoring network consists of
<br /> two units: the Forward Unit and the Austin Unit. Section 1 provides a description of the
<br /> monitoring network, site inspections, and standard observations; Sections 2 and 3 include
<br /> discussions of water quality data for 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 17 lysimeters (Figure 1-1). Well
<br /> MW-24 was constructed in 2007 anticipation of the proposed southwesterly expansion of
<br /> 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 18 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 constructed as replacements to wells
<br /> AMW-5 and AMW-19B, which were abandoned, and wells AMW-13B, AMW-21,
<br /> AMW-22, and AMW-23 were constructed as part of an on-going evaluation monitoring
<br /> program(EMP). The detection monitoring program (DMP) wells are used to detect a
<br /> potential release from the landfill, while the corrective action program (CAP) wells are
<br /> used to evaluate changes in water quality caused by releases from the landfill and by
<br /> subsequent corrective action measures. Monitoring points at the Austin Unit have been
<br /> constructed to monitor the groundwater/surface water at the facility as follows:
