Soil cuttings were temporarily stored on-site in 55-gallon DOT approved drums pending laboratory analysis, <br /> waste profiling, and proper disposal. Labels were affixed to the drums indicating the contents of the drums, <br /> date of drilling, and location of site. <br /> STANDARD PROCEDURE FOR <br /> EQUIPMENT DECONTAMINATION <br /> Equipment that could potentially contact subsurface media and compromise the integrity of the samples was <br /> carefully decontaminated prior to drilling and sampling. Drill augers and other large pieces of equipment were <br /> decontaminated using high pressure hot water spray. Samplers, groundwater pumps, liners and other <br /> equipment were decontaminated in an Alconox® (or equivalent) scrub solution and double rinsed in clean tap <br /> water rinse followed by a final distilled water rinse. <br /> The rinsate and other wastewater were contained in 55-gallon DOT-approved drums, labeled (to identify the <br /> contents, generation date and project) and stored on-site pending waste profiling and disposal. <br />
