Memorandum Date: 03/19/97 To: TRC Members From: Mary Meays, San Joaquin County Environmental Health Division RE: 45 East Harding and 2500 Navy Members, Unfortunately, I am unable to attend the March 20, 1997 meeting. I have summarized my thoughts regarding the two sites that are before you today, that I have provided oversight. 45 East Harding - Recommend Further Monitoring Chevron elected to destroy wells which were not in the footprint of the proposed Taco Bell Facility, despite my strong objection. I objected because the wells which were destroyed were screened above and below first water. The wells that Chevron elected to retain with the exception of MW3 and MW7, are all screened below first water. Chevron has taken the position that until the TRC has met and finds that additional monitoring is required they will not replace any wells which were destroyed. I have included a copy of my last comment letter, the summary table with the most recent groundwater sample results, and a summary of the well construction details for your information. Also as part of Taco Bell's (new property owner) construction activities an old domestic/facility well was discovered. A sample was recently collected; however, the results of analysis have not been submitted. A notice to abate - destroy the well has been forwarded to Taco Bell. 2500 Navy Drive - Recommend Completion of Assessment and Monitoring I have included a copy of my correspondences dated October 10, 1995 and July 15, 1996 regarding this site. The well was installed based on field observations of the geologist on site rather than taking into consideration the former investigation at the facility and was only sampled twice in 1995. Also, an addendum was submitted and commented upon to complete the investigation of the remaining contamination; however the work plan was never implemented.
