Ground And Surface Water Interaction Near A Plywood Manufacturing Facility On The Lake Roosevelt Shoreline, Kettle Falls, Washington, Paul W. D. Humphreys
Ground And Surface Water Interaction Near A Plywood Manufacturing Facility On The Lake Roosevelt Shoreline, Kettle Falls, Washington, Paul W. D. Humphreys
WWU Graduate School Collection
From April 1994 to December 1996, a water quality investigation was performed at the Boise Cascade Plywood Plant in Kettle Falls, Washington. This investigation was required by the Washington Department of Ecology to assess possible contamination from the process water lagoon and wet log storage area on the groundwater and nearby Lake Roosevelt. Water samples were collected from 11 groundwater monitoring wells, the lagoon, and two lake-shore seeps, and the samples were analyzed for a variety of chemical parameters. Water elevation data were also collected to evaluate the physical nature of the interaction between ground and surface water. The primary …

Dairy Farming And The Effects Of Agricultural, Nonpoint-Source Pollution On Stream Water Quality, Johnson Creek Watershed, Whatcom County, Washington, Max Thomas Wills
WWU Graduate School Collection
The Johnson Creek watershed, which supports one of the highest densities of dairy farms in Washington State, suffers from degraded stream water quality, primarily in the form of high fecal coliform concentrations, elevated nutrients, and low levels of dissolved oxygen. Despite the implementation of best management practices (BMPs) over the past two decades, poor stream water quality has persisted. The Washington State Department of Ecology (DOE) is therefore required under section 303(d) of the federal Clean Water Act, to establish a Total Maximum Daily Load (TMDL) policy for the basin as a means of remediating the impaired water bodies. The …
