Quilcene Bay
In response to concerns that increased use of ground- and surface-water supplies in watersheds in Washington leaves insufficient in-stream flow for fish and other users, the Washington State legislature passed the Watershed Management Act of 1998, which encourages watershed planning at the local level. As part of this planning, stakeholders within a Water Resources Inventory Area (WRIA) need to...
Bainbridge Island
Ground water is the sole source of drinking water for the City of Bainbridge Island in Kitsap County, Washington. As the population grows, demand for ground water grows, too. However, because ground water is limited by area and by the potential for seawater intrusion, the City recognizes in the Water Resources Element of its comprehensive plan that water resources must be carefully managed and...
Fort Lewis
Fort Lewis is a 135-square-mile U.S. Army post in Pierce County, Washington, located just south of Tacoma. The Environmental and Natural Resources Division of Fort Lewis wishes to evaluate the effectiveness of the current and potential remediation activities at the Logistics Center, a regional maintenance facility at Fort Lewis where pump-and-treat systems are being used to remediate chlorinated...
Colville River Basin
The Colville River Basin is a 1,007-square-mile area located in Stevens County in northeastern Washington. Following the guidelines of Washington's Watershed Management Act of 1998, water-resource planning in the basin is being conducted within a Water Resources Inventory Area (WRIA). Local citizens representing a wide range of water resource interest groups, together with local, state, and...
Island County
Island County consists of two major islands, Whidbey and Camano, and lies in northern Puget Sound, north of Seattle. Whidbey Island has an area of about 165 square miles and Camano Island an area of about 45 square miles, for a total area of about 210 square miles. Ground water is the primary source of water on the islands, and the ground-water system is fairly well understood, due in part to...
SUBASE Bangor
SUBASE Bangor is a 6,785 acre Navy installation located on Hood Canal in Kitsap County, Washington. Currently it serves as the home port to eight Ohio-class TRIDENT missile submarines, but historically the site served as a Naval Ammunition Depot. As a result of the historical activities at Bangor, numerous contaminated sites have been identified. Contaminants include ordnance chemicals, trace...
McChord Air Force Base
During the investigation of a jet fuel bulk storage area, trichloroethene (TCE) was detected in ground water beneath McChord Air Force Base, near Tacoma, Washington. Monitoring wells were installed on the base to determine the extent of the TCE. In March 2000, after six monitoring wells were installed in the residential area to the west of the base, TCE was detected at concentrations above the...
Puget Sound-Willamette Trough
More than 70 percent of the population of Washington and Oregon resides in the Puget Sound-Willamette Trough, which stretches north-south on the western side of the Cascade Range. The area is one of the principal regional ground-water systems in the Nation, but little is known about the quantity and quality of the ground water, the regional flow system, or the interaction of the system with...
Pierce County Groundwater
The rapid growth of population in the Tacoma-Puyallup area in Pierce County has placed increasing demands on the ground-water resource. Most domestic water needs are met by wells completed in the several hundred feet of glacial deposits that underlie the area, and about 9,000 persons are served by a single spring on the southwestern side of Puyallup. Most of the population relies on individual...
