FREMONT ST_ , STOCKTON, CA <br /> SIVE CODE: 1.782 <br /> Prepared for <br /> San Joaquin County PHS <br /> Environmental Health Services <br /> by <br /> Wm. J. Hunter & Associates <br /> Sept. 1994 <br /> PURPOSE OF WORK: <br /> On June 8, 1994, two (2) 1 , 000 gallon UST' s which had contained <br /> unleaded gasoline were removed from the site along with a fuel <br /> dispenser and associated piping. Soil samples were taken from <br /> beneath the tanks, and from the product line & the site of the <br /> fuel dispenser. (Refer to PLATE IV for the locations of those <br /> samples. ) The soil samples from the product line & pump were <br /> non-detect for BTEX & THP--G, but all. four of the samples from <br /> beneath the tanks revealed measureable levels of those compounds_ <br /> TABLE I summarizes the the results of the analysis; copies of the <br /> laboratory reports are included as EXHIBIT G_ It was reported <br /> that groundwater entered the excavation during the work, but no <br /> water samples were taken. The removed spoil was returned to the <br /> hole & barracades were placed around the site. <br /> The excavation is situated in the parking lot area in front of <br /> the building, and while there is no significant safety hazard, it <br /> does interfere with parking. Because of possible safety prob- <br /> lems, and the fact that the removed spoil which was returned to <br /> the hole should be removed before closing the exca'v'ation, we are <br /> proposing to remove as much additional contaminated soil as <br /> possible, take additional soil samples, fill the hole with clean <br /> material & cover with asphalt. <br /> Because of the shallow depth to the water table at this location, <br /> it is realized a groundwater investigation will be required. A <br /> program to conduct that work will be prepared and submitted to <br /> the San Joaquin EHD after the excavation & sampling covered by <br /> this workplan has been completed and the results analyzed. <br /> PROPERTY ADDRESS: <br /> 1401 W.
