1 <br /> A.Teichert&Son Inc.Mobile Equipment Shop 103 N.'E'St.Stockton,GA. <br /> Remedial Action Plan March, 1994 <br />�• Executive Summary <br /> A soil vapor extraction (SVE) pilot test was completed on a newly constructed 4-inch <br /> diameter, 80-foot deep well. The well transects a limited gasoline-impacted vadose zone <br /> and extends below the water table located approximately 70 feet below ground surface. <br /> Soil samples collected during well construction indicated elevated concentrations of <br /> gasoline constituents consistent with previous work completed at the site. The SVE pilot <br /> test created a vacuum on the new well, inducing air flow through the contaminated vadose <br /> zone and removing volatile gasoline constituents through advection. Data generated by <br /> the test includes air-sample chemical analysis of gasoline constituents, vacuum data from <br /> M peripheral wells establishing a radius of influence, and air flow data at the test well head <br /> that may be utilized to design and construct an SVE remediation system. <br /> Based upon the results of the well construction, sampling and vacuum-flow testing, SVE <br /> is feasible at this location. The SVE remediation may be expected to generate sufficient <br /> 1 vacuum and radius of influence to remove substantial volumes of gasoline constituents <br /> from an area encompassing known areas of elevated contamination. The soil vapor <br /> generated by SVE will require treatment before release into the atmosphere. <br /> A SVE remediation system compatible with design criteria is recommended for site <br /> remediation. <br /> 1 <br /> 1 <br /> I <br /> 1 <br /> 1 <br /> 1 <br />
