o971c*-2 <br /> Soil samples will be collected in an area, behind the annex, where a <br /> 1 foot wide strip of soil and rubble is exposed. This strip of land is <br /> 197 feet long and is bounded by the building foundation and the paved <br /> surface of the adjacent boat storage facility. The sample collection <br /> points will be located every twenty feet. At each collection point, a <br /> sample will be taken at the surface and at depths of one and two feet (if <br /> possible) . Due to workspace limitations, the sampling will be done using <br /> k a power auger or a hydraulic jack hammer. <br /> The shallow soil samples will be collected and placed into labeled, <br /> teflon lid jars. These soil samples will be analyzed for heavy metals <br /> u` <br /> rf such as copper, lead, nickel, and tin, and for pH. Initially only the <br /> surface samples will be analyzed. if contaminants are found in excess of <br /> regulatory standards in the surface samples, the next deepest sample will <br /> be analyzed. if significant contamination is observed at the two foot b„ � <br /> level additional samples will be collected and analyzed. J "� ✓oC <br /> 'We propose to advance five soil borings to three feet below static <br /> groundwater level at locations outside the building. The exact location <br /> of each boring will be determined by drill rig accessibility, ground <br /> structures, and underground utilities. The approximate location of theseh -. - <br /> borings is shown in Figure 2. one boring will be located upgradient and <br /> four borings downgradient from suspected sources. Monitoring wells will <br /> be installed on a temporary basis. once the wells have provided us with <br /> the sought after information, it is our intention to abandon the wells. <br /> The wells will be used to determine the local groundwater gradients, <br /> tidal influences, and provide a means of sampling the groundwater. The <br /> upgradient well will also serve as a background sample. <br /> During the soil boring operation, soil samples will be collected using a <br /> Standard Penetration Sampler. Soil samples will not be retained for , S } <br /> analysis, but will be examined by a geologist for stratigraphic control. <br /> Each boring will be fitted with a monitoring well, and after well <br />
