Water Quality Monitoring Report
<br />Forward Landfill
<br />1.0 INTRODUCTION
<br />40 On behalf of Forward Inc. (Forward), this report presents water quality monitoring data
<br />generated during the first quarter 2014 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 (RWQCB)
<br />Order No. 115-2014-0006. For reporting purposes, the water quality monitoring network
<br />consists of two units: the Forward Unit and the Austin Unit. Section 1 provides a
<br />description of the monitoring network, site inspections, and standard observations;
<br />Sections 2 and 3 include discussions of water quality data for the Forward and Austin
<br />Units, respectively.
<br />C�
<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). Monitoring
<br />wells at the Forward Unit have been constructed to monitor groundwater at the facility
<br />as follows:

<br />WMW-D-02
<br />Note: * - Piezometers are sampled in the event that the "A" well in the dual depth well pairs is dry.
<br />As presented on the following table, the monitoring network at the Austin Unit currently
<br />includes 33 groundwater monitoring wells, two domestic wells, and two surface water
<br />monitoring stations (Figure 1-1). The detection monitoring program (DMP) wells are
<br />used to detect for a potential release from the landfill, while the corrective action
<br />program (CAP) wells are used to evaluate changes in water quality and the effectiveness
<br />of the corrective action measures. Of note, the 19 evaluation monitoring program
<br />(EMP) wells were constructed as part of an on-going investigation.
