Hanford 200 Areas Vadose Zone Characterization

DOE Richland Operations Office (DOE-RL) performs characterization of the vadose zone in the vicinity of liquid waste disposal sites and solid waste burial grounds in the 200 Areas at the Hanford Site near Richland, WA.

The 200 Area plateau is the site of chemical processing plants used to separate and recover plutonium and uranium from irradiated reactor fuel elements. In addition to highly radioactive waste stored in underground tanks, processing operations resulted in discharge of approximately 346 billion gallons of chemically contaminated, low-activity liquids to the vadose zone in the 200 Areas.

Scavenged waste from some high-level waste tanks was also discharged to the vadose zone. Much of this discharge occurred through ponds or engineered drainage structures such as cribs, tile fields, retention trenches, or reverse wells.

Burial grounds were established in the 200 Areas where solid wastes generated during Hanford operations in the 200 Areas and radioactive wastes from offsite have been stored.

Numerous cased boreholes exist in and near waste disposal sites. Additional investigations in these boreholes and proposed boreholes are planned. Spectral gamma logging of these boreholes will provide valuable information regarding the nature and extent of vadose zone contamination associated with gamma-emitting radionuclides.

Scope of Project

Development of a database of existing boreholes and associated geophysical log(s) or geological data. The database will associate most boreholes with adjacent waste sites.
Characterization data acquisition (spectral gamma logging of the 200 Area boreholes).
Data evaluation and reporting.
Technical support to on-going site characterization, remediation, monitoring, and modeling activities.
Routine reporting.

Project Objectives

Provide data of known and defensible quality.
Develop a baseline of the contamination distribution that will permit future data comparisons.
Develop new technologies for enhanced vadose zone characterization.
