Box 5811 <br /> San Mateo, California 94402 <br /> Subject: Status Report, Third Quarter 1993, ARCO Service Station No. 0548, 1612 <br /> Hammer Lane, Stockton, California. <br /> Mr. Carmel: <br /> At the request of ARCO Products Company (ARCO), RESNA Industries (RESNA) is <br /> conducting an environmental investigation at the subject site (shown on Plate 1). We have <br /> prepared this status report on the work conducted during the third quarter 1993. Work <br /> included groundwater monitoring. <br /> BACKGROUND <br /> Work performed prior to this quarter 'included drilling fourteen soil borings and installing <br /> four groundwater monitoring wells and three vapor-extraction wells. Residual hydrocarbons <br /> were analytically identified in soil samples collected from borings near the tank cavity. <br /> Minor concentrations of hydrocarbons were detected in soil samples collected from soil <br /> boring near the dispenser islands. <br /> • <br /> In April 1993, RESNA observed drilling of five soil borings (B-15 through B-19) and <br /> construction of one groundwater monitoring well (MW-5) at the site. Results of analyses <br /> indicated gasoline hydrocarbons were not detected in the sample collected from the borings, <br /> with the exception of one sample collected from 41.5 feet below grade in boring B-15. <br /> Drilling of soil boring B-18, a product line was accidently fractured and leaked product into <br /> adjacent soil. RESNA collected a soil sample from 6 feet below the product line (S-6-PL1); <br /> gasoline hydrocarbons were detected in this sample. <br /> 0 <br /> .' 1001ccar <br /> 30044-8 <br /> t <br /> I• <br />
