323 West Elm Street <br /> CEJ Lodi,California 95240 <br /> BAUMBACH & PIAZZA, INC. Phone(209) 368-6618 <br /> TO: File <br /> FROM: Terry Piazza <br /> DATE: October 20, 1986 <br /> SUBJECT: Woodson Estates II <br /> Meeting with Richard Hill and Chuck McLaughlin, State Department of Health <br /> Services, October 14, 1986. <br /> See attached for information taken from their file. <br /> Per State file, the depth to ground water is 88 feet, estimated clean up <br /> cost is $300,000.00 <br /> Lodi Airport was contaminated in two sites. <br /> a. Plane wash down area on South side of Jahant Road at Frontage Road <br /> "T" intersection. <br /> b. West end of runway. <br /> There were no dumping pits. Contamination was from agricultural chemicals <br /> dropped on ground or asphalt. <br /> State visited site in 1982-83 and 84 and tested soil and wash-down water. <br /> (tests attached) <br /> h <br /> Talk with McLaughlin: <br /> a. Asked him "if developer contributed $100,000.00 of the $300,000.00 <br /> required for clean-up, could this move us up in State priority list?" <br /> Answer was indirect and not encouraging. <br /> b. Told him of plans to test near by wells for contamination. He warned <br /> that the data obtained would only be useful if we knew which acquifer <br /> or acquifers that water was drawn from. <br /> c. State would probably want additional tests run according to the state <br /> manual . <br /> Talked to Nelson Laboratories yesterday. Costs of water tests are approximately <br /> $100.00 each + technician time. We have to determine well depth and stratas <br /> used. <br /> I contacted the Local Health District to getallowable levels of contamination <br /> of water. The allowable levels are in ppb. The attached tests are in ppm and <br /> are surface soil contamination. <br /> I suggest we attack the situation of determining hazards from the toxic <br /> waste site as follows : <br /> a. Test near by wells for water quality and not worry about which acquifer <br /> is supplying water. <br /> b. If the tests show contamination, we should consider stopping work. <br /> c. If the tests shown no contamination, we should find out what acquifers <br /> the wells are drawing from. <br /> d. We should then meet with Ron Valinoti , the toxics specialist from the <br /> Local Health District, and pool our data with the County's data from —5— <br /> the water used in the two nearby restaurants. <br />
