Remediation System Installation <br /> `•' Mel Bokides Petroleum, Inc. <br /> 501 W. Lodi Avenue, Lodi, California <br /> 1.0. INTRODUCTION <br /> At the request of Mr. Nicholas Bokides of Mel Bokides Petroleum. Inc., _IcAwncecl <br /> GeoEnvlromnental. Inc. (AGI:) has prepared this report documenting installation of a soil vapor <br /> extraction and in-situ air-sparging remediation system at 501 W. Lodi Avenue (site), Lodi, <br /> ('alifornia. <br /> Nine vapor extraction wells and ten air-sparging wells were installed in May 2000. A soil vapor <br /> extraction system and air-sparging twit were also installed during June and July 2000. System <br /> operation was initiated in July 2000. <br /> Background information and previous site investigation activities, along with distribution of <br /> petroleum- impacted soil and ground water were described in the C'OITectit'e 4c6017 Plan, dated 15 <br /> .lune 1999, prepared by AGE. The site and the surrounding; area are illustrated in Figure 1. <br /> StrUCtures, well and boring locations are illustrated on Figure 2. <br /> 2.0. PROCEDURES <br /> All field work was performed in accordance with San Joaquin County Public Health Services - <br /> Environmental Health Division (PIIS-EIID) and Central Vallcy Regional Water Quality Control <br /> Board (CVRWQCB) guidelines for the investigation of underground storage tank (UST) sites and <br /> asa described in Remedial,fiction Work Plem - Ai(r x rst 1999 dated 24 August 1999 and as approved <br /> by the PHS-EHD. Field procedures for well installation, network installation and system monitoring <br /> are described below. <br /> 2.1. DRILLING AND SAMPLING <br /> On 15 through 19 May 2000, 19 soil borings were advanced at the site. The soil borings were <br /> advanced using a CME-751-1T or CME-85 drill rig. equipped with 8.25-inch diameter hollow-stem <br /> augers to advance borings V W i through V W 1 1 and IAS 1 through JAS 1 O. The drill rigs and crews <br /> were supplied by West Haz Mat Drilling. Auger returns generated by drilling were stored on-site on <br /> visqueen plastic, pending laboratory analysis. Soil samples were not collected from the soil borings. <br /> 2.2. SOIL SCREENING <br /> Soil l:rom auger returns generated by drilling were screened for the presence of organic vapor using <br /> an organic vapor meter (OVM) equipped with a photo-ionization detector (PID: Thermo <br /> Environmental 580A_ 10.0 cV. calibrated to isobutvlene). <br /> -Irhanced(:cEEnir-,iumcutal,Inc. <br />
