1,0 INTRODUCTION
<br /> On behalf of Forward Inc. (Forward), this report presents water quality monitoring data
<br /> generated during the fourth quarter 2011 monitoring period and also presents an annual
<br /> summary of the monitoring results for the 2011 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; and Section 4 presents an annual summary for the
<br /> Forward and Austin Units.
<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). Monitoring
<br /> wells at the Forward Unit have been constructed to monitor groundwater at the facility as
<br /> follows:

<br /> The monitoring network at the Austin Unit currently includes 26 groundwater monitoring
<br /> wells, two domestic wells, and two surface water monitoring stations(Figure 1-1). Of
<br /> note, wells AMW-I 3B, AMW-I 8B, AMW-2 1, AMW-2 I S, AMW-22, AMW-22S,
<br /> AMW-25,AMW-28, AMW-29, AMW-29S, AMW-30, and AMW-30S were constructed
<br /> as part of an on-going evaluation monitoring program(EMP) but are not monitored under
<br /> this program. The detection monitoring program (DMP)wells are used to detect for 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:
