Optimal groundwater contamination monitoring using pumping wells

by IWA Publishing  (Aug. 1, 2010)

This study presents a new method for selecting monitoring wells for optimal evaluation of groundwater quality. The basic approach of this work is motivated by difficulties in interpolating groundwater quality from information collected for only few sampled wells. The well selection relies on other existing data relevant to contaminant distribution ...
