Thompson & Folger West Page 14 of 16 Our Project Number: LE5080594 February 10, 2008 to the irrigation channel however there is no evidence to suggest that the drums are a contaminant at this time. The plugged and abandoned dry hole well on parcel -08 was not evident during the site visit. Assuming it remains properly sealed; it should not be considered an environmental issue on the property at this time. The LUST case located on the adjacent property to the east at 7001 Rond Road, no longer appears to pose an environmental threat to the subject property based on the supervised clean up by the CRWQCB and case closed status. If water wells are not properly operated and maintained, they can serve as contamination conduits to groundwater. In this case, there is no evidence to suggest that wells or septic systems may be contaminant pathways on the subject property or vicinity. 5.0 CONCLUSIONS AND RECOMMENDATIONS Given the historical uses of agricultural chemicals and petroleum products on the subject property, meaningful conclusions regarding the presence or extent of such material cannot be determined without soil sampling and analysis. Such sampling and analysis is especially warranted in the conversion of agricultural land into residential use, which is not the case for this property. Should future residents of the subject property be interested in determining the quality of their drinking water, EHD should be contacted for direction regarding the potential for impacts to groundwater from the agricultural history of the property and vicinity. The portion of Hog Slough and the irrigation channel south and west of the subject property respectively, should be periodically monitored for indiscriminate disposal of potentially hazardous materials. The staining around the above-ground storage tank on parcel -05 should be cleaned up, and the tank should be placed in a secondary containment to prevent further soil staining. If construction is to take place in the future in the vicinity of the plugged and abandoned well on the subject property, the Department of Oil, Gas, and Geothermal Resources should be contacted for direction before proceeding. Because no staining was observed in the vicinity of the transformers, the transformers are not considered an environmental threat to the subject property at this time. Should the property owners or the EHD be concerned about PCB contamination from the transformer, PG&E should be contacted to test, retrofit, or replace the transformer. Any wells or septic systems identified which will not remain in use should be abandoned under EHD oversight.
