Few studies, and none in Oregon, have examined the presence and change of water quality parameters over time in popular natural swimming areas. This information is necessary to better understand water quality and risk of illness from either fecal contamination or cross-infection from other swimmers. The purpose of this study...
Benzene is a widespread urban pollutant and monitoring results show concentrations are particularly high in Portland, Oregon.

Using GIS, this study creates a predictive model of a distinct population of French-Canadian settlers, highlighting shared environmental characteristics of known sites that may have factored into their decision-making process as they chose locations for their farmsteads. While traditional historic and archaeological research has been conducted on French Prairie, the...
This study focuses on iodine-131 detected in milk samples from the Dairy Science Unit at Cal Poly, San Luis Obispo, California following events at the Fukushima Dai-ichi Nuclear Power Plant in March of 2011. The samples were collected as part of the Diablo Canyon Nuclear Power Plant (DCPP) Radiological Environmental...
The purpose of this qualitative study was to describe and communicate a student-constructed model of student services for electronic distance education (EDE). This study seeks to answer the following questions: Do students enrolled in EDE perceive a need for student services? If not, why not? Which services do students want/need?...
Increasing costs for wastewater treatment provide incentives to
evaluate system alternatives, especially among small communities with limited
financial resources. Land treatment systems with hybrid poplar tree
plantations are becoming increasingly popular as one such alternative in the
Pacific Northwest.
Land treatment systems are made up of a complex dual system:...
