Fecal coliform bacteria in stream sediments : sampling methodology, measurement and modeling the impact on stream water quality

Creator:

Church, Wendy S.

Abstract:

Three studies were conducted related to the measurement and impact of stream sediment fecal coliform (FC) bacteria on stream water quality. In part one an enumeration technique for sediment FC was defined and statistically characterized. This characterization necessitated the development of a sample splitting mechanism, which was found to split...

Chemical and isotopic patterns of nitrate variability in the southern Willamette Valley, Oregon

Creator:

Vick, Christopher Flanders

Abstract:

A relatively stable, persistent and historical problem with elevated NO₃⁻ concentrations in rural drinking wells in the southern Willamette Valley, Oregon is evident. What is the origin of NO₃⁻ in rural drinking water wells in this area? The answer to the question is not simple. Many non-point sources contribute to...

Infiltration and temperature characterization of a wastewater hyporheic discharge system

Creator:

Stewart, Ryan D.

Abstract:

The Clean Water Act imposes Total Maximum Daily Load (TMDL) limits on pollutant concentrations within wastewater effluent; in Oregon, thermal discharge is one of the pollutants subject to regulation. The City of Woodburn, Oregon, funded a series of pilot scale studies to investigate the utility of natural systems to reduce...
