The purpose of the addendum is to detail the investigative work to be conducted <br /> !� iI during the soil vapor extraction (SVE) system evaluation. The following work will be completed <br /> I <br /> j �' during the site evaluation: <br /> I 1) Explore the condition of all SVE wells at the site by evaluating each well for the <br /> presence or absence of groundwater in or above the screened interval including <br /> measurements of depth to groundwater and the total depth of casing. <br /> 2) Calculate the volume of soil in the treatment area, including mass volume of <br /> R <br /> hydrocarbons based on existing soil boring data. <br /> I <br /> 3) Determine the maximum flow rate and vacuum rating of the blower motor, including <br /> type (i.e., rotary, regenerative, etc.). <br /> j 4) Describe all instrumentation currently available or necessary in the testing an <br /> operational phases for the SVE system. p <br /> II <br /> q 5) Calculate the radius of influence and pole volume exchange rates which may support <br /> these values. <br /> 1 <br /> i <br /> ENVIRONMENTAL GEOLOGICAL • ENGINEERING GEOTECHNICAL <br /> i <br /> 0. <br />
