CALIFORNIA REGIOO WATER QUALITY CONTROL BOARD* Cal/EPA CENTRAL VALLEY REGION d 344 Routim Road, Suite A Sactamento, CA 95827-3003 Phone(916)255-3000 Pete Wilson,Governor FAX(916)255-3015 93 MAY 14 PM 2: 41 12 May 1998 Mr. Wing Jun Ng, President First Jun Jun Investment, Inc. 1217 Skycrest Drive, #2 Walnut Creek, CA 94595-1811 PROPERTYACCESS TO CONDUCTABANDONED WELL INVESTIGATIONAT 6632 PACIFIC AVENUE, LINCOLN VILLAGE CENTER GROUNDWATER CLEANUP, STOCKTON, SAN JOA Q UIN CO UNTY The Central Valley Regional Water Quality Control Board (Board) is overseeing investigation and cleanup of tetrachloroethene(PCE) contaminated groundwater at the Lincoln Village Center. The work is being conducted by Levine Fricke Recon (LFR), Inc., for a group of former dry cleaners jointly known as the Settling Dry Cleaning Defendants (SDCDs). The investigation has determined that a groundwater plume of PCE extends east of Lincoln Center and underlies your property at 6632 Pacific Avenue. On 30 March 1998, LFR sent you a letter explaining the nature of the investigation and requesting access to the parking lot at 6632 Pacific Avenue to locate an abandoned well. Your 3 April 1998 response denied LFR access to conduct this investigation. The abandoned well was apparently part of the former Safeway operations. According to Safeway, the well was abandohed in 1971 or 1972 when the previous Safeway building was demolished and the present building constructed. Safeway cannot provide any specifics on the method of well abandonment. Since this well extended to a depth of 240 feet, improper abandonment could allow the shallow PCE-contaminated groundwater to move downward into the regional aquifer which is used for drinking water supply. Therefore, it is critical that an investigation be done to locate this well and abandon it properly, if necessary. Under the California Water Code Sections 13267 and 13304, all persons owning property underlain by contaminated groundwater may be held responsible for investigation and remediation of the contamination. Generally, the Board has exercised its discretion to hold responsible only persons who own the land which was the source of pollution, and not landowners whose land sits over the plume. Nonetheless, it is common that those persons remediating sites require access to adjacent land to complete their investigation and remediation.
