Water quality data for the period 1982 through 1983 from about 350 wells in three Miocene basalt units in the Columbia Plateau regional aquifer system, Washington, show that the quality of groundwater generally is suitable for most uses. The dominant water type is calcium magnesium bicarbonate at shallow depths, and evolves toward sodium bicarbonate at depth. Calcium magnesium sulfate...

This data report presents groundwater information collected and analyzed as part of the U.S. Geological Survey 's Columbia Plateau Regional Aquifer System Analysis study. The information was gathered from July 1982 through September 1985 in the part of the aquifer system in central and eastern Washington, and north-central and eastern Oregon. The report consists of three volumes: volume...

Gas Works Park, in Seattle, Washington, is located at the site of an abandon gasification plant on Lake Union. Wastes deposited during 50 years of plant operations (1906-1956) have extended the shore line 100 ft and left the park soil contaminated with a number of hazardous material. Soil contaminants include polynuclear aromatic hydrocarbons (PAHs), polychlorinated biphenyls, pesticides...

The May 18, 1980, eruption of Mount St. Helens generated a debris avalanche, lateral blast, lahars and tephra deposits that altered mainstream and tributary channels within the Toutle River drainage basin. Channel cross sections were monumented and surveyed on the North Fork Toutle River and its tributaries, South Fork Toutle River, Green River, and Toutle River in 1980 and 1981. These...

The flood-carrying capacity of the Puyallup River 's leveed channel from its mouth to the city of Puyallup exceeds the 100-yr-flood discharge at most locations. Upstream from the city of Puyallup the flood-carrying capacity also is less than the 100-yr flood at many locations. In King County the flood-carrying capacity would be greater than the 100-year flood nearly everywhere if the...

Immediately after the devastating May 18, 1980, eruption of Mount St. Helens, a program was initiated by the U.S. Geological Survey to study the streamflow and sediment characteristics of streams impacted by the eruption. Some of the data gathered in that program are presented in this report. Data are presented for two key sites in the Toutle River basin: North Fork Toutle River near Kid...

Three domestic wells that withdraw groundwater from an alluvium-filled trough cut into granite were found to be contaminated with the organic solvents tetrachloroethene, trichloroethene, 1,1,1-trichloroethane, and 1 ,2-trans-dichloroethene. The suspected source of contamination is a nearby septic-tank sludge disposal area. There is concern that the affected aquifer is tributary to the...
