1.0 INTRODUCTION On behalf of Forward Inc. (Forward), this report presents water quality monitoring data generated during the fourth quarter 2007 monitoring period and also presents an annual summary of the monitoring result for the 2007 monitoring year for the Forward Landfill in San Joaquin County, California. Monitoring was performed in accordance with requirements listed in the Central Valley Regional Water Quality Control Board (RWQCB) Order No. R5-2003-0049. For reporting purposes the water quality monitoring network consists of two units: the Forward Unit and the Austin Unit. Section 1 provides a description of the monitoring network, site inspections, and standard observations; Sections 2 and 3 include discussions of water quality data for the Forward and Austin Units, respectively. 1.1 MONITORING NETWORK The water quality monitoring network at the Forward Unit currently includes 15 groundwater monitoring wells (five of which are dual depth well pairs), one domestic well, two surface water monitoring stations, and 17 lysimeters(Figure 1-1). Well MW-24 was recently constructed in anticipation of the proposed southwesterly expansion of the landfill. Monitoring wells at the Forward Unit have been constructed to monitor groundwater at the facility as follows: Forward Unit Groundwater Monitoring Network Monitorin Point Monitoring Point I.D.

Of note, wells AMW-5R and AMW-19BR were recently constructed as replacements to wells AMW-5 and AMW-19B which were recently abandoned. The detection monitoring program (DMP) wells are used to detect a potential release from the landfill, while the corrective action program (CAP) wells are used to evaluate changes in water quality caused by releases from the landfill and by subsequent corrective action measures. Monitoring points at the Austin Unit have been constructed to monitor the groundwater/surface water at the facility as follows: D:\2007-0043\Fo—ardAustin_4QO7.doc 1 Geologic Associates
