STATE OF CALIFORNIA - Environmental Protectiorincy PETE WILSON, Governor <br /> CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD ` <br /> CENTRAL VALLEY REGION _ <br /> 3443 Routier Road, Suite A <br /> Sacramento, CA 95827-3098 <br /> PHONE: 19161255-3000 RECEIVED JUN 0 0 1995 <br /> FAX: 19161 255-3015 <br /> 5 June 1995 <br /> Ms. Leah Goldberg <br /> McDonough, Holland & Allen <br /> 1999 Harrison Street, Suite 1300 <br /> Oakland, CA 94612 <br /> PRELIMINARY FIELD INVESTIGATION: KOPPEL STOCKTON TERMINAL <br /> Thank you for submitting the recent letter regarding the Koppel Stockton Terminal at 2025 West <br /> Hazelton Avenue, and the workplan for the deeper soil investigation. Also enclosed was the <br /> Preliminary Field Investigation, which summarizes the field work conducted by RWQCB staff in <br /> March, and contains the analytical results reported by your laboratory, Weston. I have talked with <br /> your consultant, Dave Marks, and we are both at a loss to explain the large discrepancy in nitrate <br /> values between the split soil samples. I have retrieved the original samples analyzed by the <br /> RWQCB laboratory; if you wish, you may submit these to the Weston lab. <br /> I have reviewed the workplan for the deeper soil investigation, and have the following comments: <br /> Because of the differences in the analytical values of the March samples, I would like to split <br /> samples with you. This time, I'd suggest that we thoroughly mix each sample in a clean <br /> bowl or bucket before splitting it into the two laboratory containers. <br /> You propose to collect samples at the 3' and 6' depths. In order to try to resolve the <br /> differences from the March samples, additional samples should be collected from the 6-9" <br /> depth, and analyzed for nitrate. <br /> With the above two comments, the workplan is approved. However, because of our agency's recent <br /> fiscal constraints, I am not able to visit the site or submit samples to our laboratory until after <br /> 30 June. <br /> Please let me know when you plan to conduct the field work. If you have any questions, I can be <br /> reached at (916) 255-3104. <br /> WENDY WYELS <br /> Ag Regulatory Unit <br /> cc: Ms. Diane Hinson, San Joaquin County Public Health, Stockton <br /> Mr. Dave Marks, Roy F.
