Hanford Site ground-water monitoring for July through December 1988

The Pacific Northwest Laboratory (PNL) monitors the distribution of radionuclides and other hazardous materials in the ground water at the Hanford Site. This Site-Wide Ground-Water Monitoring Project also evaluates the impact of past and present Site operations on the environment. The specific objectives of the project are to (1) determine the distribution of radionuclides and nitrate ion to define the extent of impacted ground water, (2) relate the distribution of these constituents to Site operations, (3) establish background concentrations for naturally occurring regulated hazardous materials, and (4) identify in the ground water those hazardous chemicals that resulted from Site operations. To meet these objectives, the Hanford Site-Wide Ground-Water Monitoring Project involves the measurement of water-table elevations and the collection and analysis of ground-water samples. 31 refs., 15 figs., 18 tabs.
