IN-SITU AIR SPARGING PILOT TEST <br /> Ell <br /> Following installation of well AW- 1 , a 48-hour in-situ air sparge (IAS) pilot study is proposed at the <br /> site to evaluate IAS as a remedial alternative; the results of the IAS pilot test will provide data to <br /> calculate an effective IAS radius of influence and determine general feasibility of IAS as a <br /> remediation alternative. Procedures for the IAS pilot test are presented in Section 4.6 . <br /> 3 . 6 , AIR SPARGING/SOIL VAPOR EXTRACTION PILOT TEST <br /> Following the 48-hour IAS pilot study, an eight-hour SVE/IAS pilot study is proposed <br /> simultaneously at the site to evaluate SVE effectiveness during IAS activities; the results of the SVE <br /> pilot test will provide data to calculate an effective SVE radius of influence for design of a SVE <br /> remediation system and determine feasibility of IAS as a remediation alternative. Procedures for the <br /> SVE/IAS pilot test are presented in Section 4.7 . <br /> iJ 3 . 7. IN-SITU OZONE SPARGING PILOT TEST <br /> Following installation of well OSW- 1 , a 4-week in-situ ozone sparge (IOS) pilot study is proposed <br /> at the site to evaluate IOS as a remediation alternative; the results of the IOS pilot test will provide <br /> data to calculate an effective radius of influence and determine feasibility of IOS as a remediation <br /> alternative. Procedures for the IOS pilot test are presented in Section 4. 8 . Additional ozoneinj ecfion <br /> 1 literature is contained in Appendix A. <br /> �J <br /> 3 . 8 . REPORT PREPARATION <br /> Results of the well installations, ground water aquifer pumping test, SVE, IAS and IOS pilot studies <br /> ! will be presented in a Problem Assessment Report (PAR). If appropriate, interim ground water <br /> remediation may be proposed, pending the completion of a Remedial Action Plan (RAP). The PAR <br /> and RAP will be in a format acceptable to the RWQCB (Appendix A guidelines), and will be <br /> reviewed and signed by a California Registered Geologist. <br /> 4.0. FIELD PROCEDURES <br /> .J All fieldprocedures will be overseen by an AGE representative under the supervision of a California <br /> Registered Geologist. Procedures forwell installations, well development, aquiferpumping test, soil <br /> vapor extraction, in-situ air sparging and ozone sparging are described below. <br /> —� Advanced GeoEnvironmental, Inc. <br /> i . <br />
