San Joaquin Street Stockton, CA 95201-0388 SUBJECT: Safeway Meat Processing Plant 1111 Navy Drive, Stockton Review Status of Groundwater Conditions Dear Mr. Sasson: On December 16, 1995, ERM-West forwarded to you the November, 1994, groundwater sampling results for the subject property. By now you should have received and reviewed the results. There has been virtually no change in the diesel concentrations over the last two and one-half years. The attached table summarizes the data to-date. In two of four samples analyzed for coliform, positive results have been reported for the sampling events in June 1992 and November 1994 . Drinking water standards are less than 1 MPN/100 ml level for coliform. The most recent sample results for November, 1994 exceed this standard by over 100 percent. Safeway has not contributed to this coliform problem. It is most likely due to releases from the 36 inch to 48 inch sewer mains located within Navy St. It is quite possible, therefore, that other contaminants may have entered the groundwater from the sanitary sewer. In your October 17, 1994 letter to Safeway, you requested Safeway to prepare a workplan to assess the lateral. and vertical extent of the hydrocarbons in soil and groundwater. Safeway requested an extension in assessing the conditions of the site, and you verbally granted that extension. After reviewing the site data generated to date, interviewing the local water purveyor (Cal Water Services Co. ) , and reviewing other underground tank site files located within the Navy and Charter Way area, Safeway does not believe it would' be beneficial, financially feasible, or necessary to pursue further site investigations. We request that the site be considered for closure for the following reasons: ®Recycled Paper
