CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD CENTRAL VALLEY REGION MONITORING AND REPORTING PROGRAM NO. _-02-_ FOR LINCOLN CENTER ENVIRONMENTAL REMEDIAION TRUST MARK A. ADAMS, TRUSTEE STOCKTON, SAN JOAQUIN COUNTY Lincoln Center is a retail shopping center located in Stockton, California situated on approximately 30 acres bounded by Gettysburg Place to the west,Pacific Avenue to the east, Douglas Road to the south, and Lincoln Elementary School to the north(see area map attached as Figure l). In 1984, a municipal water supply well located on the western edge of Lincoln Center (Lincoln Village Maintenance District Well#1 or LVMD #1)was found to contain 120 ug/l of tetrachloroethene (also known as perchloroethylene or PCE) and 20 ug/1 of trichloroethylene (TCE). Two additional municipal supply wells, LVMD #2 and#6,were later found to contain PCE in excess of the maximum allowable contaminant levels (MCLs). These three aforementioned wells, and an additional nearby municipal supply well (LVMD #4),were abandoned and sealed (grouted) in 1992. Investigations revealed that the contamination, originating from releases to the sewer from dry cleaning facilities located at Lincoln Center,has resulted in pollution of the groundwater beneath, and in the vicinity of, Lincoln Center with volatile organic compounds including PCE,TCE, cis- and trans-1,2-dichloroethene, and vinyl chloride. PCE was detected in the groundwater at a maximum level of 85,000 ug/I in a 05/1997 sample collected from monitoring well MW-006A. In 1998, a Phase I, Interim Removal Action consisting of 17 shallow groundwater extraction wells, located along the eastern boundary of the Lincoln Center Property, and an air stripping/vapor-phase carbon treatment system were constructed. As of December 2001, a total of 44 million gallons of groundwater had been treated and 2,095 pounds of PCE and 1,372 pounds of Total Petroleum Hydrocarbons,measured as gasoline (TPHg),had been removed. In 1999, a Phase II Interim Removal Action consisting of a network of 35 soil vapor extraction wells and a vapor-phase carbon treatment system was constructed. As of December 2001,the system had removed 6,200 pounds of PCE from the soil vapor. Lincoln Properties, Ltd., owner of portions of the Lincoln Center property,brought suit in the United States District Court, Eastern District of California, against certain current and former tenants that operated dry cleaning facilities at the Lincoln Center(Case No. CIV-S-91 760 DFL (GGH)). In settlement of the lawsuit, the Lincoln Center Environmental Remediation Trust (Lincoln Trust) was created by Order and Decree of the Court. The Lincoln Trust was funded primarily a Site Response Insurance Policy paid for by the insurers of the settling drycleaners for the purpose of performing an appropriate investigation and remediation of the hazardous substance contamination released to the environment from certain drycleaning facilities at Lincoln Center. Mr. Mark Adams was appointed by the court as the Trustee for the Lincoln Trust. This Monitoring and Reporting Program (MRP) is issued pursuant to Section 13267 of the California Water Code and is designed to delineate groundwater contaminant plumes and determine whether remediation efforts are effective. The Lincoln Trust Trustee shall not
