' Test Boring Results—Robmhood Irrigation Well Replacement <br /> Cleanup and Abatement Order No 5-00-707 EAI Project No 1232 <br /> As discussed in the Work Plan, fuel hydrocarbon impacts to the RIW resulted due to the fact <br /> that the RIW had slots beginning at depths as shallow as 40 feet bgs However, since PHS- <br /> EHD requirements will preclude slots in the new irrigation well at depths less than 200 feet <br /> bgs, including properly sealing the upper zone from pollution, e g , conductor casing (see <br /> Section 4 0), it is unlikely that the new irrigation well will impact any of these UST sites <br /> Further, if necessary as a precautionary measure, pressure transducers/data loggers could be <br /> installed in selected off-site ground water wells associated with the identified UST sites (see <br /> Figure 3) during pump tests to be conducted for the new irrigation well Data from such a <br />' study will determine if use of the new irrigation well impacts these sites <br />' 2.3 Production Wells <br /> In order to determine the presence or absence of production wells within 2,500 feet of the <br />' proposed new irrigation well location, EAI relied upon data maintained by the California <br /> Department of Health Services, Drinking Water Program and the California Department of <br /> Water Resources The results of this work identified no production wells (other than the <br /> existing RIW taken out of service by the RWQCB in August 2000) within 2,500 feet of the <br /> proposed new irrigation well location However, two production wells were identified within <br /> approximately 3,000 feet of the proposed new irrigation well location as follows (see Figure 3) <br />' STATE ID 0 OWNER TYPE TOTAL DEPTH <br /> 2N/6E-21P1 State of California Division of Architecture Unknown 238' <br /> 02N/06E3 California Water Service Company Unknown Unknown <br /> 1 <br /> SAR 1232TFITBORING -3- <br /> ENVIRONMENTAL AUDIT, INC <br />
