The wells v 1 be purged with a pump and dedicated disposable tubing until at least three well <br /> casing volumes are removed and/or after groundwater temperature, pH and electrical conductivity <br /> values have stabilized. Groundwater will be sampled from the wells using disposable <br /> polyethylene bailers and laboratory-supplied containers. Each sample container will be <br /> transported in an iced cooler With chain-of-custody documentation to a state of California certified <br /> hazardous waste testing laboratory. The lab will analyze the two groundwater samples for <br /> dissolved oxygen,suffatelsulfitelsulfide, nitrate/nitrite, total dissolved iron, methane, magnesium, <br /> and heterotrophic plate counts. <br /> d 11:11's <br /> Storage an <br /> All waste, I soil cuttings generated during drilling will be contained in 55-gallon drums for temporary <br /> on-site storage, pending waste proffing and proper disposition. Equipm6atiosate, purged <br /> groundwater, and SVE test moisture knock-out liquid will be contained its 56-gallon drums, <br /> pending waste profifing and proper disposition. Waste activated carbon Will also be stored <br /> : <br /> temporarily on-site, until this waste can be profiled and transported off-sitefor regeneration and/or <br /> disposal. <br /> 3.
