Box 2009 0 (1601 East Hazelton Avenue) • Stockton, California 95201 <br /> �lOR <br /> (209)468-3400 <br /> AUG 19 1991 v <br /> U <br /> ALDO FREGGIARO <br /> PORT OF STOCKTON <br /> P 0 BOX 2089 <br /> STOCKTON CA 95203 <br /> RE: Port of Stockton IN REPLY REFER TO SITE CODE: 1.2829 <br /> 2201 W. Washington <br /> Stockton, CA 95203 <br /> San Joaquin County Public Health Services, Environmental Health <br /> Division (PHS/EHD) has reviewed the Groundwater Investigation <br /> Report received on July 3, 1991. Soil near the former underground <br /> fuel storage tank was excavated and soil samples were taken at 13 <br /> feet. A "grab" water sample was also analyzed. All samples <br /> analyzed were found to be nondetectabie for hydrocarbon <br /> contamination. <br /> Although there appears to be no significant soil contamination, the <br /> quality of the groundwater beneath and downgradient from the former <br /> underground storage tank cannot be determined from a "grab" sample. <br /> Site certification cannot be granted without groundwater <br /> confirmation sampling from properly constructed monitoring wells. <br /> Upon completion of the monitoring wells (at least one well must be <br /> placed in a downgradient direction) and confirming data, site <br /> certification will be considered. <br /> If you have and questions, contact Eleanor Ratliff, REHS, of my <br /> staff at (209) 468-3454. <br /> Jogi.
