Lower White River pH TMDL Groundwater Support
The Lower White River between the cities of Buckley and Auburn in Pierce County has periodically exceeded Washington's upper surface-water criterion for pH (8.5). These pH excursions are thought to result from excess nutrient inputs to river.
To address the river’s pH problems, Ecology conducted a series of field surveys between July 2011 and December 2012 to evaluate water-quality conditions within the river. This effort will ultimately lead to the development of a numerical water-quality model that Ecology staff will use to prepare a formal cleanup plan for the river. This study will evaluate the thermal and water-quality influences that groundwater imparts to gaining reaches of the river.
