During the development of the new wells, one <br /> well will be used to conduct a 24-hour group test on <br /> the shallow aquifer. Information on aquifer properties <br /> will be provided by this test which are necssary for <br /> final extraction well design. <br /> Task 2 -- Sampling <br /> I . Obtain samples from the three new and four existing <br /> wells for laboratory analyses. These samples will be <br /> delivered to a certified laboratory and analyzed for: <br /> benzene, toluene, and xylene concentrations using EPA <br /> method 602. <br /> Task 3 -- Tank Removal <br /> 1 1. Remove from site, the excavated 500-gallon tank and <br /> I dispose of this tank in accordance with regulations. <br /> Task 4 --- Project Management, Review, <br /> and Report Preparation <br /> 1. This task In the project management of this phase <br /> of the project, engineering review, and report <br /> preparation of the above activities. This will include <br /> an analysis of laboratory data and the subsequent <br /> I findinas. It will also include a preliminary ground <br /> water remediation program proposal and associated cost <br /> estimates for implementation. <br /> PHASE II Design-of a Vapor Phase Extraction System <br /> Introduction <br /> The objective of this proposed vapor phase extraction <br /> projec is to reme sate the-gasoline contain nate soil in <br /> the vadose zone (the unsaturated zone beneath the ground <br /> surface and above ground water) adjacent to the tank <br /> excavation area. <br />
