C Savone's Versadrill; under WEGE drilling contractors license <br /> and direct supervision If ground water and/or a 5 foot ur <br /> thicker layer of .a low permeability clay (with properties <br /> indicating it to be a pu_aible aquatard) is/are encountered the <br /> borla s will be terminates: and a sample obtained Along with <br /> supervising the drilling the jxk-site WEGE geologist will also <br /> conduct the health and safety monitoring and provide the safety <br /> plan for this site (health and safety officer), Appendix E, and T <br /> sample collection and preservation for this site. All soil n � <br /> excavated during the boring process will be placed on and covered �l <br /> with a 6 mil polyethylene liner(s) Selected borings maybe <br /> utlized as vapor recovery/monitoring wells and if ground water is <br /> encountered ground water recovery/monitor wells, see Figures 6 and <br /> Appendix F-boxing($)/monitor well permit <br /> VSRTIC&L Ezrw IN HXGAVATIOM <br /> Borings will be performed in the excn�dtion using the Versadrill <br /> The Versadrill is a crane operated solid flight auger, that is <br /> capable of extending out into an excavation and augering a 36" <br /> diameter hole in 3 foot intervals Sampling c the Versaricilled <br /> 4 <br />
