J. H. KLEINFELDER &ASSOCIATES <br /> File: PW86-1041/14:381 <br /> ` July 29, 1985 <br /> Page 7 <br /> t <br /> System Effectiveness <br /> During the field test operation, system effectiveness <br /> will be evaluated from VOC content of the exhaust gas, <br /> volumes of gas extraction, and air pressure observed at the <br /> well point piezometers. Several exhaust gas samples will be <br /> collected and analyzed as part of this task. <br /> Based upon the data obtained during sampling of the <br /> extraction line, the quantity of organic volatile chemicals <br /> removed from the vadose zone in the target area will be <br /> estimated. This estimated mass of chemicals removed by the <br /> stripping system will be compared to the total estimated <br /> f inventory for subsurface chemicals within the target area. <br /> The sults of the field test will produce the <br /> technical results of the process information to the final <br /> design of the vapor phase extraction system, conceptually <br /> depicted on Figure 4. <br /> The final deliverable product will be the design plans <br /> and a budgetary cost estimate for the complete system <br /> installation. This approach will allow for maximizing the <br /> existing information and the results obtained during the <br /> field test while minimizing expenditures. In addition the <br /> necessary information on system construction costs, <br /> operation, and maintenance will be available at the <br /> 1 conclusion of the final design phase. <br /> Data Management <br /> All soils and ground water data will be compiled <br /> E according to standard JHK&A operating procedures. All field <br /> it analyses and observations will be included as appendices to <br /> the task report. Data analysis will be comp,ieted using <br /> JHK&A computer facilities. Reports will be sub,nitted upon <br /> completion of the Field Test. <br />
