Quantification of the nitrate attenuation capacity of low-permeability Missoula Flood deposits in the Willamette Valley of Oregon

Creator:

Arighi, Louis M.

Abstract:

Low-permeability geologic units may offer significant chemical and hydraulic protection of adjacent aquifers, and are important for managing groundwater quality, especially in areas with significant non-point source contamination. Nitrate in the Willamette Valley is attenuated across the Willamette Silt, a semi-confining unit overlying a regionally important aquifer. To quantify the...

Temporal and spatial variability of groundwater nitrate in the southern Willamette Valley of Oregon

Creator:

Mutti, Jeffrey Glenn

Abstract:

Groundwater nitrate contamination is a well-documented issue in the Southern Willamette Valley (SWV) of Oregon, as a Groundwater Management Area (GWMA) has recently been declared. As a GWMA, groundwater nitrate monitoring must occur until regional concentrations are below 7 mg/L NO3-N. However, the presence of temporal variability can make it...

Mitigating Microplastics : Development and Evaluation of a Middle School Curriculum

Creator:

Kowalski, Marie

Abstract:

Microplastics, plastic marine debris less than 5 mm in size, is a threat to the health of our oceans. One important way to reduce microplastics in our oceans is to educate people about the issue, particularly future decision-makers. In this study, a middle school curriculum was developed using current scientific...
