LNW0.1 "m. L TEIXEIRA-SOUZA PROPERTY Page 16 WKA No. 5475.03 June 2, 2003 Lknown regional impairments to ground water quality beneath or in the vicinity of the subject property during review of the regulatory agency databases described in this report. ]�erc et/G 6- The subject property contains at least two known water supply wells. If the wells will cease to be used, the water supply wells must be properly decommissioned; this procedure requires a well L abandonment permit for each well from the San Joaquin County Environmental Management Department, Environmental Health Division. The existing residences on the subject property are L and/or were serviced by at least two on-site septic systems. The septic systems are unlikely to have affected subsurface soils with hazardous materials,based on expected residential waste effluent as opposed to commercial or industrial wastewater discharges. When the property is Lredeveloped, each of the septic systems and associated leach fields and/or dry wells must be properly abandoned in accordance with the recommendations of a qualified geotechnical L engineer. L Similarly, abandonment and backfilling of the existing dairy wastewater ponds and the irrigation tailwater pond must be completed in conformance with the recommendations of an experienced geotechnical engineering firm, and in close consultation with the earthworking, environmental L and soils engineering staff when the abandonment work occurs. It will be important to remove all accumulated organics and redoxymorphic soils from the bottoms of on-site ditches, irrigation water and wastewater ponds. The organics may be applied at agrarian rates to the surrounding cultivated fields,but we emphasize that this activity should be completed in coordination with the project geotechnical engineer and earthworking staff. These operations are necessary for both geotechnical (soils stability of pond backfill) and environmental reasons (mitigate potential i formation of methane gas). L In summary, we have performed a Phase IEnvironmental Site Assessment in conformance with Lthe scope and limitations of ASTM Standard Practice E 1527-00 for the Teixeira Property located in San Joaquin County, California. We have made no exceptions to, or deletions from, the Standard Practice with respect to the Phase 1-site assessment aspects of our work. This L Assessment has revealed no evidence of Recognized Environmental Conditions in connection with the subject property. L L INK L WALLACE•KUHL „ Er ASSOCIATES INC.
