AGS <br /> 3.2 SAMPLING PROTOCOL <br /> All field work will be performed in accordance with the Site-specific Health and Safety <br /> Plan, included in Appendix B of this Work Plan. <br /> 3.2.1 Site Clearance <br /> All proposed soil boring locations will be cleared for subsurface utilities prior to <br /> beginning work at each OWS site. The location and type of any subsurface utilities <br /> adjacent to a boring site will be indicated on the ground with aerosol spray paint. The <br /> site clearance will incorporate the use of various types of geophysical exploration <br /> equipment (magnetometer, EM probes, etc.), as appropriate. In addition, the <br /> appropriate permits will be obtained and the Navy will be informed of the proposed <br /> schedule prior to the initiation of the field work. <br /> 3.2.2 Soil Borincs <br /> Seven soil borings will be advanced into subsurface materials at each of the three OWS <br /> sites for a total of 21 borings for the project. The borings will be advanced to an <br /> approximate depth of 10 ft bgs, 5 ft below the anticipated depth to groundwater at the <br /> sites. One vadose zone soil sample will be collected for chemical analysis from each cf <br /> the borings located in the immediate area of the OWS system. The soil samples will be <br /> collected from depths generally equivalent to (but not exceeding 2 ft below) the bottom <br /> of the OWS and other components of the OWS system. If the bottom of the tank vault <br /> occurs below the water table, the tank vault soil sample will be collected from a point <br /> just above the water table. No soil samples will be collected for chemical analysis from <br /> the more distant up- and downgradient borings. <br /> Table 1 lists and identifies the soil borings for each OWS site and also provides the type <br /> and number of samples for each boring and the purpose for the boring. Altogether, a <br /> total of 15 soil samples will be collected at the OWS sites.
