Sources of Mercury in Sinclair Inlet Project

The sediments in Sinclair Inlet within Puget Sound, Washington have elevated concentrations of a number of organic compounds and elements including mercury. Following remediation actions under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), it was determined that there is insufficient information to determine whether remedial action taken at OU B Marine with...

Cedar River Peak Flow Management

The Cedar River watershed provides two-thirds of the water supply for the greater Seattle metropolitan region, in addition to being home to numerous federally listed salmon species. The City of Seattle, through Seattle Public Utilities (SPU), works closely with the Cedar River Instream Flow Commission (IFC) to adaptively manage flows on the Cedar River. Seattle operates its water management...

Little Spokane Hydrogeology

The Issue: Groundwater is an important resource for domestic, commercial, and agricultural usage in the Little Spokane River Basin, and groundwater discharge helps maintain streamflow in area streams. Consequently, as the population grows, and commercial and agricultural activity increase, so does the demand for groundwater. However, the quantity of usable groundwater, and the...

Phosphorus SPARROW Model for the Yakima River

The Issue - During the 2004-07 irrigation season, nutrient concentrations in the lower Yakima River were high enough at certain times and locations to support the abundant growth of periphytic algae and macrophytes which resulted in large daily fluctuations in dissolved oxygen concentrations and pH levels that exceeded the Washington State water-quality standards for these...

Chimacum GW Model

Projected increases in population and development in northeastern Jefferson County, Washington, are expected to lead to increased groundwater withdrawals in the Chimacum Creek Basin. Changes in land use and climate could reduce groundwater recharge, thereby reducing groundwater available for drinking and for baseflow to streams that host endangered fish species.

The Issue: Fresh groundwater withdrawals for irrigation from 66 principal aquifers in the United States comprised approximately three-fourths of total groundwater withdrawals in the year 2000. The magnitude of these withdrawals is certainly substantial but difficult to quantify because few states actually monitor groundwater withdrawals for irrigation. Water-resource managers...

Atmospheric Deposition and Surface-Water Chemistry in Mount Rainier and North Cascades National Parks, U.S.A., Water Years 2000 and 2005-2006

High-elevation aquatic ecosystems in Mount Rainier and North Cascades National Parks are highly sensitive to atmospheric deposition of nitrogen and sulfur. Thin, rocky soils promote fast hydrologic flushing rates during snowmelt and rain events, limiting the ability of basins to neutralize acidity and assimilate nitrogen deposited from the...

Petrology of the 2004-2006 Mount St. Helens lava dome -- implications for magmatic plumbing and eruption triggering

Eighteen years after dome-forming eruptions ended in 1986, and with little warning, Mount St. Helens began to erupt again in October 2004. During the ensuing two years, the volcano extruded more than 80×106 m3 of gas-poor, crystal-rich dacite lava. The 2004-6 dacite is remarkably uniform in bulk-rock composition and, at 65 percent SiO2 ,...
