The use of long term, large scale pumping data to determine the regional recharge rates through fractured till and lacustrine materials

摘要

This paper presents an analysis of historical pumping rates for three large well fields in Madison County, Ohio, where ground-water recharge is solely by infiltration through fractured glacial tills. By combining this withdrawal information with long-term static water level data, a minimum sustainable recharge rate can be quantified for the region and applied to other local land-use decisions.
