Weber Ave., Third Floor <br /> Stockton, CA 95202 <br /> Subject: Workplan for Contamination Assessment <br /> 26239 Miller Avenue,Escalon, CA <br /> Dear Mr. Infurna: <br /> Ground Zero Analysis, Inc. (Ground Zero) is writing on behalf of Mr. Robert Van Spronsen of <br /> Berbarian Properties, LLC, to present a workplan for assessment of possible soil contamination at <br /> the subject property (Figure 1). The proposed work is intended to provide an indication of the <br /> presence and magnitude of any soil contamination resulting from previous clandestine drug <br /> laboratory operations at the property. The proposed work is also intended to deal with the <br /> contained wastewater pumped from the septic system. <br /> Background <br /> On June 24, 2004, Network Environmental Systems, Inc. (NES) inspected the subject property, <br /> which was known to have been affected by clandestine drug laboratory activity. The work was <br /> done in response to a letter from the San Joaquin County Environmental Health Department(EHD) <br /> dated August 17, 2004. NES collected wipe samples from various locations inside the mobile <br /> home. Soil samples were also collected from soil adjacent to the house and the irrigation well, and <br /> a water sample was collected from the septic tank serving the mobile home. Samples were <br /> analyzed for chloride,phosphorus, iodide,pH, and methamphetamine. <br /> Methamphetamine was detected in the wipe samples collected by NES. The water sample collected <br /> from the septic system contained also contained methamphetamine, as well as low levels of <br /> phosphorus and chloride. The soil samples collected did not contain methamphetamine but did <br /> contain elevated levels of phosphorus. The results of NES's work were reported in a Preliminary <br /> Site Assessment Report created for the owner, Mr.Robert Van Spronsen,dated July 23,2004. <br />
