The subsurface piping previously connected -an aboveground manifold located at southeast <br /> corner of the site building to.the following remedial wells: VW-1 through VW-4, MW-1, MW-1, SW-1, <br /> SW-2, and RW-1 (Figure 2). All pipes formerly consisted of Schedule 40 PVC material and were located <br /> within a common trench, thus easing_removal. <br /> A back hoe was used to uncover the lines for removal. During removal at each wellhead, the line was <br /> cut close to the well, and the stub to the well was permanently capped. <br /> 520 Third Street,Suite 104 w Oakland,California 94607 + Telephone 510-893-5160 + Fax 510-893-5947 <br />
