1.0 INTRODUCTION
<br /> On behalf of Forward Inc. (Forward),this report presents water quality monitoring data
<br /> generated during the fourth quarter 2008 monitoring period and also presents an annual
<br /> summary of the monitoring results for the 2008 monitoring year for the Forward Landfill
<br /> in 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 /> I 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 NET
<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-I 9BR were constructed as replacements to wells AMW-
<br /> 5 and AMW-19B, which were abandoned, and wells AMW-13B, AMW-21, AMW-22,
<br /> and AMW-23 were constructed as part of an on-going evaluation monitoring program
<br /> (EMP). The detection monitoring program (DMP) wells are used to detect a potential
<br /> release from the landfill, while the corrective action program (CAP) wells are used to
<br /> evaluate changes in water quality caused by releases from the landfill and by subsequent
<br /> corrective action measures. Monitoring points at the Austin Unit have been constructed
<br /> to monitor the groundwater/surface water at the facility as follows:
