Job: J. MELT, - TRACY March 15, 1940 backhoe, soil samples will be collected from the sides and bottom of the excavation. The backhoe will excavate the soil sample materials from the pit to the surface to facilitate the sample collection. The samples will be collected from relatively non-disturbed soil materials remaining in the backhoe bucket. Immediately upon the excavation of these materials (in the backhoe bucket) to the surface, a clean 3- inch (length) by 2-inch (diameter) brass sample tube will be driven into these materials (using a clean wooden mallet) for soil sample collection. TECO anticipates that eight to ten soil samples should be collected from the excavation for documentation. The depths and number of soils samples may vary upon the request of the San Joaquin county Public Health Services and/or conditions encountered in the field. Upon recovery of the samples, they will be handled as outlined in the Sampling Protocol in Attachment 2. The samples will be delivered to a State-certified laboratory, Anametricx, Inc. (DHS Certification # 151) , located in San Jose, California. Per State "LUPT" guidelines, the samples will be analyzed for: TPH as gasoline (EPA Method 5020 or 5030) ; BTEX and Chlorinated Hydrocarbons (EPA Method 8240) ; Total Oil and Grease (State Method 503 D and E) ; EPA Method 8270; Chromium, Lead, and Zinc (ICAP or AA) . Unless otherwise specified by you, the samples will be submitted for normal ten, working-day results. If the samples indicate that detectable levels of contaminants remain in the soil materials, the excavation, monitoring, sampling and laboratory procedures will continue (as outlined above), providing site conditions permit. This procedure shall continue, until the contaminant levels remaining in the soils are below detectable levels; THE ENVIRONMENTAL CONSTRUCTION CO. 4 I�
