Waste Area Grouping (WAG) 4 is one of 17 WAGs within and associated with Oak Ridge National Laboratory (ORNL), on the Oak Ridge Reservation in Oak Ridge, Tennessee. WAG 4 is located along Lagoon Road south of the main facility at ORNL. WAG 4 is a shallow-waste burial site consisting of three separate areas: (1) Solid Waste Storage Area (SWSA) 4, a shallow-land burial ground containing radioactive and potentially hazardous wastes; (2) an experimental Pilot Pit Area, including a pilot-scale testing pit; and (3) sections of two abandoned underground pipelines formerly used for transporting liquid, low-level radioactive waste. In the 1950s, SWSA 4 received a variety of low-and high-activity wastes, including transuranic wastes, all buried in trenches and auger holes. Recent surface water data indicate that a significant amount of {sup 90}Sr is being released from the old burial trenches in SWSA 4. This release represents a significant portion of the ORNL off-site risk. In an effort to control the sources of the {sup 90}Sr release and to reduce the off-site risk, a site investigation is being implemented to locate the trenches containing the most prominent {sup 90}Sr sources. This investigation has been designed to gather site-specific data to confirm the locations of {sup 90}Sr sources responsible for most off-site releases, and to provide data to be used in evaluating potential interim remedial alternatives prepared to direct the site investigation of the SWSA 4 area at WAG 4.
