Prior to monitoring, the wellcaps were <br /> opened to allow the water in each well to stabilize to atmospheric pressure. The DTW was <br /> measured to the nearest 0.01 foot from the top of the well casing using an ORS Environmental <br /> Equipment INTERFACE PROBE Well Monitoring System. <br /> Offices throughout the U.S..Canada and Overseas <br />
