Book Description
The basalt formations underlying the Hanford site are being considered for characterization and evaluation as a deep geologic repository for defense and commercial radioactive wastes. To understand the hydrology of the Hanford area, we need to know if the ground-water system is in steady state and what impact a change in surface stress from artificial recharge may have on the underlying basalt aquifers. Researchers at Pacific Northwest Laboratory are supporting efforts to understand these issues by illustrating how changes in wastewater disposal activities at the Hanford site have altered the configuration of the water table surface with time. The objective of this work was to determine the magnitude and direction of changes in the elevation of the water table across the Hanford site from 1950 to 1980. Plots of the magnitudes of water-level changes occurring over 5-year intervals from 1950 through 1980 are presented. The water-level changes that occurred during each 5-year interval are related to water discharges from nuclear fuel reprocessing facilities or other discharge sources. The plots of water-level changes show large water-level increases in the vicinity of the Separations Area (200 East and 200 West) from 1950 to 1960; the rate of increase of water-level changes grows more slowly from 1960 to 1970, while the areal extent of the mounding continues to expand. Only small changes occur from 1970 to 1980; during this time period, the unconfined system appears to be in approximate equilibrium with the sources. Based on previous experience, it is believed that an increase in ground-water mounding will begin to appear near the 200 East Area B Pond as a result of the increased discharges from the restart of PUREX in 1983.

Book Description
The purpose of this Environmental Impact Statement (EIS) is to provide environmental imput into the selection and implementation of final disposal actions for high-level, transuranic and tank wastes located at the Hanford Site, Richland, Washington, and into the construction, operation and decommissioning of waste alternatives. Specifically evaluated are a Hanford Waste Vitrification Plant, Transportable Grout Facility, and a Waste Receiving and Packaging Facility. Also an evaluation is presented to assist in determining whether any additional action should be taken in terms of long-term environmental protection for waste that was disposed of at Hanford prior to 1970 as low-level waste (before the transuranic waste category was established by the Atomic Energy Commission but which might fall into that category if gernerated today.).

Book Description
On the Home Front is the only comprehensive history of the Hanford Nuclear Site, America's most notorious plutonium production facility. Located in southeasternøWashington State, the Hanford Site produced most of the plutonium used in the atomic bombs that effectively ended World War II. This book was made possible by the declassification in the 1980s of tens of thousands of government documents relating to the construction, operation, and maintenance of the site. In a new epilogue, Michele Stenehjem Gerber provides a detailed history and commentary on the first twelve years of the Hanford cleanup project?the largest waste cleanup program in world history.

Book Description
Irrigation applied west of the Hanford Site and wastewater management practices on the Hanford Site resulted in significant changes in the configuration of the water table between December 1979 and December 1989. In the Cold Creek Valley, located in the western part of the Hanford Site, the water table rose more than 3 m (9 ft) between December 1979 and December 1989. Since 1969, the water table in the Cold Creek Valley has been rising, primarily in response to irrigation practices in the Upper Cold Creek Valley. The largest areal changes have occurred in the vicinity of production facilities in the 200 Areas where ground-water mounds have developed since operations began in 1943. During the 1940s and 1950s, two ground-water mounds developed as a result of wastewater management practices in the 200 Areas, one beneath 216-U-10 Pond in the 200-West Area and one beneath 216-B-3 Pond near the 200-East Area. During the 1960s, the ground-water mounds grew moderately before reaching near-equilibrium conditions during the 1970s. During the 1980s (December 1979 to December 1989), stresses imposed on the unconfined aquifer caused recurrence of unsteady state conditions. In the 200-West Area, the water level declined more than 2.5 m (8 ft) between December 1979 and 1989. Most of the decline occurred after 1984, which correlates with a reduction in wastewater discharge caused by the decommissioning of 216-U-10 Pond in 1984. The decline in the water table occurred mostly in the area between the 200-West Area and the Yakima Ridge basalt, which outcrops above the water table to the south of the 200-West Area. 50 refs., 31 figs., 1 tab.
