We would like t see three(3) borings <br /> (not mud rotary)in a transect line(center boring along an axis from the source a,ea through the domestic <br /> well and 50'downgradient of the domestic well),with each boring 50' apart(either side of centerline <br /> boring). Groundwater samples would target the CPTs' logged permeable zones and include: near the <br /> water table,sand zone near 130' bgs,sand zone near 140' bgs and sand stringer near 155'. Actual <br /> groundwater sample depths could be based on lithology from direct push core samples. Please submit the <br /> Work Plan by 15 January 2015. <br /> G W-> <br /> Jim Barton <br /> James L.L.
