Abstract
A quasi-three-dimensional digital groundwater flow model of a shallow outwash aquifer system at Olean, New York, was developed to study the effects of several pumping alternatives on groundwater flow and stream seepage. Nitrogen compounds have contaminated the aquifer in an industrial park in North Olean. Pumping from seven industrial production wells and a purge well has created a cone of depression within which all nitrogen compounds are contained, thus preventing their migration to nearby private, municipal, and industrial-supply wells. A simulated total shutdown of an industrial well field and the purge well indicates that groundwater flowing laterally southward to southwestward from the area of contamination would require about 5 yr to reach a municipal well field along the Allegheny River. Simulation of a partial shutdown with only three main production wells and the purge well or just the three production wells indicate that all nitrogen-bearing groundwater would be captured. Pumping from only the purge well would allow contaminated groundwater along the southwestern edge of the site to escape and, in 8 to 9 yr, reach the municipal well field. (USGS)
