The purposes of this report are to describe the quality of shallow ground water in alluvial aquifers of the Willamette Basin and to identify relationships between shallow ground-water quality and various natural and anthropogenic factors. Several natural and anthropogenic factors (soil characteristics, cumulative thickness of clay above open interval of well, surficial geology, and land use) were evaluated because of the potential for these factors to either control or be related to contaminant occurrence and spatial distribution. Spatial distributions of nitrite plus nitrite, phosphorous, pesticides and pesticide degradation products, volatile organic compounds (VOCs), trace elements (primarily arsenic, a trace element of local concern), and radon were evaluated for 1993-95. Ancillary chemical data--nitrite, chloride, tritium (H-3), and dissolved-oxygen (DO) concentrations--also are presented. |
