Soil parameters such as cone bearing, sleeve friction,friction <br /> ratio and pore water pressure will be measured and recorded as a cone penetrometer is advanced to <br /> depth. Rinseate generated during drilling activities will be containerized in properly labeled DOT- <br /> approved 55-gallon drums, and stored on-site in ari.area lacking public access. Based on CPT <br /> lithologic findings, discrete grab water samples-will be collected in selected saturated intervals of <br /> porous and permeable material. A HydroPunch sample tool will be pushed into the specified zone, <br /> then withdrawn approximately three feet to expose an inlet screen.The interior of the sampling tool <br /> fills with water and a 1-inch outer diameter(O.D.)stainless steel bailer will be lowered and utilized <br /> to extract a ground water sample. <br /> All other procedures will be followed as described in the above referenced work plan addendum.
