GE � <br /> GENESIS ENGINEERING&REDEVELOPMENT <br /> SAMPLING AND ANALYSIS PLAN <br /> Drilling Procedures <br /> Each location will be cleared for underground utilities through a USA service alert request <br /> and by a private utility locator. In addition,the initial 5 feet at each location will be <br /> advanced using a hand auger. <br /> Direct push drilling technology will be used to advance the borings for collection of soil <br /> samples. The direct push drilling process consists of a truck mounted or limited access <br /> hydraulic system used to push a 4-foot long, 2-inch diameter hollow rod into the subsurface. <br /> A 1.75-inch diameter vinyl acetate plastic sample sleeve is inserted into the rod to collect <br /> continuous 4-foot long soil samples. The soils brought to the surface in the sample sleeves <br /> for the borings will be continuously logged to the maximum depth of the hole. <br /> Soil cuttings generated during this process shall be placed in DOT rated 55-gallon drums, <br /> labeled, and moved to a common drum staging area prior to off-Site disposal. All direct push <br /> boreholes shall be abandoned according to state and local guidelines. <br /> Sampling Procedures <br /> Reconnaissance Groundwater Sampling <br /> Reconnaissance groundwater samples will be collected by constructing a temporary <br /> monitoring well in the borehole. At the selected depth interval, a 3/4 inch, 5-foot long <br /> section of screen will be lowered through the center of the drill rod, and the drill rod will then <br /> be retracted 5 feet to expose the well screen. Water will be allowed to enter the well screen, <br /> and a groundwater sample will be collected using a decontaminated bailer and decanted into <br /> the laboratory supplied sample bottles. Samples will be analyzed for nitrate using EPA <br /> Method 300.1 and for ammonium using method SM 4500. <br /> A-1 <br />
