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...

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...
