Soil "samples <br /> encountered in the borings will be visually classified by an AGE geologist in accordance with the <br /> Unified Soil Classification System(USCS).Additionally,soil samples will be field screened for the <br /> presence of volatile organic compounds using an organic vapor meter(OVM)equipped with a photo- <br /> ionization detector(PID). <br /> 4.3. EQUIPMENT DECONTAMINATION <br /> Prior to use, all sampling tools will be thoroughly rinsed with clean water after being washed with <br /> a solution of Alconox. All probing rods will be cleaned prior to advancement at each probe boring <br /> location. <br /> i <br /> 4.4. BORING ABANDONMENT <br /> Following collection of soil samples,each borehole will be filled to the ground surface with a cement I, <br /> grout. The grout mixture will consist of Type I/II portland neat cement and not more than 6 gallons <br /> of water per 94-pound sack of cement. The grout will be deployed through a tremmie pipe. If <br /> required, a grouting inspection will be scheduled with EHD personnel. <br /> i <br /> ii <br /> Advanced GeoEnvironmental,Inc. <br />
