Input/output energy analysis of regional water pollution control

Creator:

Heggen, Richard J.

Abstract:

Two strategic approaches to water quality control in Oregon's Willamette River are presently being utilized: point source treatment and flow augmentation. Dry weather releases from reservoirs are for authorized purposes other than water quality. Reservoirs can participate in pollution control by summer flow augmentation where authorized water resource objectives (flood...

Spatial and temporal variations of bioavailable polycyclic aromatic hydrocarbons in the lower Willamette River

Creator:

Sower, Gregory J.

Abstract:

Urban rivers with a history of industrial use can exhibit spatial and temporal variations in contaminant concentrations that may significantly affect risk evaluations and assessment of remediation efforts. To more effectively estimate human and ecological health risks, we evaluated the spatial and temporal distribution of polycyclic aromatic hydrocarbons (PAHs) in...

Distribution of bioavailable metals and a human health risk assessment from fish and crayfish in the lower Willamette River, Oregon

Creator:

Krissanakriangkrai, Oraphin

Abstract:

In this study the impact of episodic events on levels of bioavailable trace metals Zn, Cu, Cr, Cd, Pb, and As (III) were determined for the lower Willamette River in Oregon. In addition, a comparison among three alternative methods for estuary sampling was conducted. Potential adverse human health risk associated...
