SECTION 3 <br /> TECHNICAL APPROACH <br /> The soil sampling and boring program will be addressed in a <br /> two-phased approach which is necessitated by the ongoing <br /> dewatering program at the facility. The scheduled completion for <br /> the dewatering of the pond is currently projected to take place <br /> on or about April 1, 1988 . Access to the basin portion of the <br /> pond area will be a directly related to the success of the <br /> dewatering program, and may have a greater impact on the second <br /> phase of the sampling program due to the need for drill rig <br /> access. <br /> PHASE I - SEDIMENT, SURFACE AND SHALLOW SOIL SAMPLES <br /> The first phase of the soil sampling program is limited to the <br /> collection and analysis of soils and sediments present on the <br /> surface and in the upper layers of the pond berm and basin areas. <br /> rThe proposed sampling program will involve collection of surface <br /> samples using a hand collection device and collection of <br /> rsubsurface samples using a small hand driven sampling device <br /> (hand auger or split spoon sampler) . All tools will be <br /> decontaminated between samples (see: DECONTAMINATION PROCEDURES) . <br /> r <br /> The top layer of sediments present in the basin and on each of <br /> the four pond berms will be collected and logged as sediment <br /> samples to differentiate them from the surface samples . <br /> r <br /> GMI <br /> r <br />
