The catch basin and connecting drain line will be cleaned with <br /> potable water. <br /> Confirmation soil samples will be collected at an approximate 20-foot spacing from the floor of <br /> the remedial excavation area both at the surface and a depth of 1 foot at each sampling <br /> location. Soil samples will also be collected from each sidewall beneath the concrete pad <br /> housing the valve assembly.
