Quarterly Report - Second Quarter 2003 HERMAN AND HELEN'S MAR1[NA 15135 Eight Mile Road, Stockton, California 1.0. INTRODUCTION At the request of Mr Andrew Smith,Advanced GeoEnvironmental, Inc (AGE) has prepared the enclosed quarterly report of environmental activities conducted at 15135 Eight Mile Road,Stockton, California The scope of work included quarterly ground water monitoring, surface water sampling and preparation of this report Monitoring wells MW-2 through MW-10 and extraction well EW-1 were monitored and sampled, and two surface water samples were collected from the island drainage channel during the second quarter 2003 Surface water samples could not be collected this quarter from the north and south ends of the drainage ditch(DDN and DDS)due to the absence of water in the drainage ditch The site and the surrounding area are illustrated in Figure 1 Structures and monitoring well and sampling locations are illustrated on Figure 2 Ground water monitoring and sample analytical data from September 1997 to the present are summarized in Tables 1 and 2 Detailed site background information can be found in Appendix A ! 2.0. PROCEDURES Field work was conducted and this report was prepared in accordance with Monitoring and Reporting Program (MRP) No 5-01-835, dated 05 June 2001, and guidelines established by San Joaquin County Environmental Health Department (EHD) for sampling ground water monitoring wells 2 1 WELL MONITORING AND EVACUATION On 11 June 2003, a Solinst water level meter was used to measure the depth to ground water in monitoring wells MW-2 through MW-10 and extraction well EW-1 relative to the tops of the well casings After water level measurements were recorded,either disposable plastic bailers or a Watera inertia pump with dedicated tubing were used to purge the monitoring wells of standing water The wells were evacuated in order of least contaminated to most contaminated, based on previous morutonng data Approximately 4 00 to 5 25 gallons of water(a minimum of 3 casing-water volumes per well)were removed from wells MW-2 through MW-5, MW-9 and MW-10 Approximately 25 75 to 28 25 gallons of water were removed from wells MW-6 through MW-8 and 73 75 gallons of water were removed from well EW-1 Groundwater temperature,pH and conductivity were measured at regular intervals during purging using an Oakton water analyzer Field sheets and data are included Advanced GeoEavnronmeatal,Inc.
