methods. The technique(s) employed will depend upon conditions encountered, and with <br /> the approval of the San Joaquin Co. EHD staff. <br /> 4. Depending upon the results of the visual inspection, the well will either be returned to <br /> service or left idle. <br /> Project 2 - Removal of contaminated soil and restoration of excavation. <br /> 1. Remove approximately 150 cubic yards of contaminated soil from excavation. It will <br /> be either: <br /> (a) stored temporarily on adjacent property owned by Tuleburg Warehouse, placed on <br /> Plastic and covered pending a decission on final disposition. If the necessary APCD <br /> ermints can be obtained, it may be remediated on site until levels of contaminants reach <br /> `acceMable levels. or - <br /> (b) transport removed soil directly to an approved landfill for disposal. <br /> The method employed will depend upon the ability to obtain the necessary permits, cost <br /> considerations, and Cleanup Fund staff approval. <br /> 2.: Bring in clean fill - estimate 400 cubic yards - fill excavation and compactas required <br /> by San Joaquin County. Repave excavation with asphalt and restore to original condition. <br /> Project 3-Soil& Groundwater Investigation. <br /> 1. Mobilize properly licensed auger rig equipped with sufficient clean flights to go to 120' <br /> without the necessity of decontaminating flights. The soil boring locations "A" & "B" are <br /> shown on PLATE V. <br /> 2.. Equipment to include continuous coring capability to allow visual inspection, screening <br /> and sampling at desired intervals. <br /> 3. Coring to begin at native soil depth, which is estimated to be at about 15' bgl at soil <br /> U locations A & B. Coring will continue to groundwater or deeper as directed by the <br /> San Joaquin Co. EHD. Groundwater is estimated to be at 75 to 80 feet below grade at <br /> this location. Soil samples to be preserved at each major change in lithology and/or <br /> evidence of contamination(either visual or PID.) <br /> 4.. Preserved samples to be transported under chain of custody to a State Certified <br /> analytical laboratory and analyzed for BTEX, TPHg, and oxygenates using San Joaquin <br /> Col EHD.methodology and detection limits. , <br /> 4 <br />
