Temporal and Vertical Variability of the Soil- and Ground-water Geochemistry of the Ashport Silt Loam, Payne County, Oklahoma

Abstract

The soil-moisture content, soil- and ground-water quality of a site nestled in a suburban neighborhood were monitored intensively over a five month period, from late January to late June, 1987. Soil- and ground-water quality was found to be relatively consistent throughout most of the study. Near the end of May, more than five inches of rain fell on the study area, ending a five week dry period. In the days following this event, significant water quality changes were observed in several of the lysimeters, and later in a shallow well. Flow through macropores is invoked as one possible explanation for this occurrence.
