CLEARWATER GROUP 229 Tewksbury Ave.,Point Richmond, CA 94801 Tel: 510-307-9943; Fax: 510-232-2823; www.clearwatergroup.com Three issues will be investigated during this project: • Possible pesticide use in the fields; • Possible leakage from the empty drums near the above ground tank (AST); • Possible underground storage tank near vertical pipes; and • The status of the water wells. SCOPE OF WORK All work will be performed under the direction of professional geologist. All field work is planned to be performed in one day. Sampling will be performed by FAST-TEK Engineering Support Services (C-57; A, Haz., Lic. # 624461) of Point Richmond, California. All soils will be logged by a geologist and screened with a photoionization detector (PID). Item 1 — Agricultural Practices: Based on the Phase I, historic agricultural practices occurred, with the possibility that pesticides were used on the fields. Clearwater proposes to collect 8 soil samples (B-1 to B-8) in the fields. The samples will be collected from 6 to 12 inches below ground surface (Figure 2). The shallow samples will be collected using a hand auger and a slide- hammer soil sampler. If soils are exceptionally dense, the Geoprobe may be used to sample the soils. Sampling methods are attached. The eight soil samples will be composited in the laboratory (4 samples to 1), so that the resulting lab work will reflect 2 composited samples (B-1 to B-4 and B-5 to B-8). The two composited samples will be analyzed for Organochlorine Pesticides by EPA Method 8081A, Organophosphorous Pesticides by EPA Method 8141B and arsenic by EPA Method 6020. Item 2 — Empty Drums: An above ground storage tank and empty drums were noted west of the chicken house and south of the garage. The AST was a propane tank, which predated natural gas service in the area. Two empty 55-gallon drums were noted near the AST. Six 55-gallon drums and one 25-gallon drum southwest of the chicken house. Regarding all drums on the property, the drum labels will be examined, and the drums will be inspected for potential leaks and corrosion. The field geologist will visually inspect the area and scrape the soil. The soil will be screened for organic vapors using a PID. If there appears to be staining, dead vegetation or discoloration, one soil sample (optional B-12 near the AST or optional B-11 near the southwest Fischer Family Trust,Stockton,CA 2 August 24,200
