On September 18, 2003 Ground Zero was contacted by the Village West Marina manager, briefly informed of the situation, and asked to contact Mr. McDougall of Marina West concerning the case. In subsequent conversations, we were informed by EHD that a meeting had taken place on September 15 between Mr. McDougall and representatives of EHD and the District Attorney's Office. We were informed that EHD would not provide regulatory oversight of the cleanup and that a workplan should be submitted to the California Department of Toxic ' Substances Control (DTSC) for approval. The District Attorney's Office indicated verbally that every effort should be made to expedite investigation and cleanup, and in particular, any cleanup necessary to ensure that winter rains did not wash highly-contaminated soil over the levee bank ' into Fourteenmile Slough. ' 3.0 BASELINE SOIL SAMPLING AND WORKPLAN PREPARATION Ground Zero personnel inspected the site and collected thirteen soil samples on September 26, 2003 in order to obtain baseline information on the magnitude and the lateral and vertical extent of soil contamination. This information was then evaluated and a workplan for contaminated soil abatement was prepared. 3.1 Soil Sampling Paint chips were visually observed along a narrow strip of bare soil on the south side of the boat repair area. The suspected area of impact or "work area" was approximately 200 feet in length and 6-10 feet in width. The work area is bounded on the south by the levee bank, which is densely overgrown with blackberry bushes; on the north by asphalt paved parking; and on the east and west by untrammeled soil with a sparse cover of brush and blackberry bushes. Soil ' samples were collected from the surface and from depths of 3-inches and 6-inches below grade at three locations in the work area. The samples were identified by X, Y & Z coordinates: distance in feet east or west (E or W) of the zero point marked on the ground, distance in feet south (S) of the asphalt and by depth in inches. In addition, surface soil samples were collected at points approximately 20 feet east and 20 feet west of the edge of the work area. Samples were also collected from the levee face at two points south of the work area. Sampling locations are ' identified on Figure 2. The soil samples were submitted to State-certified GeoAnalytical Laboratories (FLAP No. 1157) for analysis of total copper using EPA Method 6010B. 3.2 Analytical Results and Distribution of Copper in Soil Copper concentrations in the samples ranged from 40 ppm to 41,000 ppm. Results are summarized in Table 1. 3
