Summary

In Indiana, there are extensive agricultural areas developed on glacial outwash deposited in floodways of major streams and on outwash fans and wind-blown sands. Because infiltration is rapid and direct in these hydrogeologic settings, groundwater is subject to degradation by nitrates derived from agricultural sources such as inorganic fertilizers, crop residues, applied manure, and manure from grazing cattle. However, an earlier investigation in Jackson County, Indiana, indicated that denitrification occurs as groundwater migrates downward, so that shallow aquifers in this type of hydrogeologic setting are candidates for remediation. As part of this investigation, participating farmers employed a variety of experimental practices [...]
