Abstract

Previous investigations in northeast and north-central Iowa have identified areas where surficially derived contaminants, particularly nitrates and commonly-used pesticides, have caused degradation of groundwater quality (Hallberg and Hoyer, 1982; Hallberg et a!., 1983, 1984; Libra et al., 1984). These studies showed that the depth to bedrock aquifers, and the presence or absence of karst features, have a major influence on the potential for surficial contaminants to reach groundwater. Geologic regions based on these criteria were delineated.
