All downhole equipment will be decontaminated using steam, prior <br /> to use. Wells will be drilled with a continuous flight hollow <br /> stem auger. All wells will has a diameter at least 4 inches <br /> greater than the casing diameter (OD). <br /> i. Core samples of the vadose zone will be taken every 5 feet. The <br /> -- final core will be taken as near as possible to the capillary <br /> fringe. <br />
