The purpose of this sampling and analysis instruction is to provide adequate information to disposition waste material generated from decommissioning of 69 selected Hanford Site groundwater wells. Sixty-seven of these wells are located in Columbia River Corridor Area 1B, and two wells are located in Columbia River Corridor Area 1A. These wells are typically noncompliant, are not in use, or are located in areas that are scheduled for excavation. In addition, the U.S. Department of Energy, Richland Operations Office has identified restoring the Columbia River Corridor as one of the three outcomes of the cleanup of the Hanford Site.
