Hanford Site Data
Fifty years of nuclear weapons production resulted in approximately 1.7 trillion liters (450 billion gallons) of liquid waste being released to the ground at the Hanford Site. Some of the associated contaminants have reached the groundwater. Hazardous chemical contaminants include carbon tetrachloride, chromium, and nitrates. Radioactive contaminants include iodine-129, strontium-90, technetium-99, tritium, and uranium.
Hanford Borehole Geopysical Logging
The U.S. Department of Energy (DOE) conducts borehole geophysical logging at the Hanford Site to detect and quantify naturally occurring and man-made gamma-emitting radionuclides in the vicinity of liquid waste disposal sites, solid waste burial grounds and at Tank Farms. Prior to October 1, 2006, this work was managed by the DOE Grand Junction Office (GJO) through a contract with S.M. Stoller Corporation (Stoller). Starting at the beginning of the 2007 fiscal year (FY-07), DOE Richland Operations Office (RL), through the central plateau contractor, Fluor Hanford, Inc., (FH) and DOE Office of River Protection (ORP), through the tank farm contractor, CH2M Hill Hanford Group (CHG) are managing the geophysical logging work.
Environmental Data Access
Commonly sought Hanford Environmental Information System (HEIS) well-monitoring data, tracking contaminants from about 1950 to the present, can be accessed via the Environmental Data Access tool (account required).
