Emplacement of <br /> the Portland cement grout specifically shall not be accomplished by "Lee fdr, bare the <br /> ground surface. <br /> Soil Sampling <br /> The proposed groundwater monitoring wells will be located immediately adjacent to the CPT <br /> berings. 'Ibe CPTs provided nearly continuous description of the lithology at cards location. <br /> Theref ne soil logging will not be conducted during installation of monitoring wells MW-8 <br /> IfuwgJrMW-13. <br /> Well Development <br /> The groundwater monitoring wells will be developed after completion. The development <br /> Procedure for each well void consist of pumping or bailing water Lom the well until the water <br /> is visibly clear, the well goes dry, or until a maximum of ten casing volumes have been <br /> removal. <br /> Groundwater Analysis <br /> Following monitoring well development, groundwater samples will be collected and <br /> submitted to a Calif num Stmt ertiGed laboratory for analysis. Groundwatu samples will be <br /> welyzed for the presence ofTPH-g, BTEX, and for five oxygenates (MME, RIPE, BTBE, <br /> TAME and TBA) using EPA Methods 8015 Modified, 8020 and 8260B, respectively. <br /> Well Surveying <br /> Upon mmplaion ofesell counteraction, flue wells will be surveyed by a licensed surveyor for <br /> location and elevation relative to mean sea level. Groundwater gradient will be sentiment <br /> utilizing wellhead elevation; and depths to water. <br /> Soil Cuttings and purge Water <br /> Soil cuttiugs gcnaated during drilling operations will be temporarily sfred on site and _ <br /> severed with plastic sheeting pending cbamcterization. A Califomis-certified disposal <br /> surbactor will remove soil cuttings to an appropriate disposal facility. Water generated <br />
