Quarterly Report - September through October 1998 <br /> Franklyn Cole Properties <br /> 7505 West Linne Road, Tracy, California <br /> 1 1.0. INTRODUCTION AND SCOPE OF WORK <br />' At the request of Mr. Franklyn Cole,Advanced GeoEnvironmental, Inc. (AGE) has prepared this <br /> Quarterly Report for the property located at 7505 West Linne Road,Tracy,California(the site).This <br /> report summarizes the operation of the remediation unit at the site. The site setting is illustrated on <br />' Figure I. Structures,borings, and former UST and dispenser locations on the site are illustrated on <br /> Figure 2. <br />' The report is prepared in accordance with San Joaquin County Public Health Services - <br /> Environmental Health Division (FHS-EHD) and Central Valley Regional Water Quality Control <br /> Board (CVRWQCB) guidelines for the corrective action of unauthorized petroleum release from <br />' underground storage tanks (USTs). <br /> i <br />' Background information and a description of prior investigations at the site was included in the Site <br /> Summary.Report - October 1996, dated 22 October 1996, prepared by AGE. Information and a <br /> description of soil vapor extraction(SVE) unit setup was summarized in Quarterly Report-June <br /> 1998, dated 15 September 1998, prepared by AGE. <br />' 2.0. PROCEDURES <br /> Over portions of the third and fourth quarter of 1998 the SVE unit extracted soil gas/vapor,from the <br />' upper and lower screen interval of well VW-I. Extracted soil gas/vapor was sampled for laboratory <br /> analysis on four occasions to monitor the extraction and destruction process. <br /> 2.1. SOIL GASNAPOR EXTRACTION <br />' The SVE system was monitored weekly and when shut-downs occurred. <br />' During each monitoring event,the flow rate of extracted soil gas/vapor was measured using a Dwyer <br /> differential pressure flow meter..Vacuum(potential)was measured at wells VW-I and VW-2 using <br /> a differential pressure magnehelic(vacuum)gauge. The organic-vapor concentration in the extracted <br /> . soil gas/vapor vapor stream was measured„before entering the blower (influent stream) and after. . <br /> exiting the burner (effluent stream) using an organic vapor meter(OVM)'equipped with a photo <br /> ionization detector (PID-Thermo Environmental 580A, 10.OeV, calibrated to isobutylene at 100 <br /> ppb). <br /> Advanced GcoEnvfronmental,Inc. <br />
