overlying perched aquifers by an unsaturated zone, mine dewatering alone would not affect perched aquifers. Mine dewatering would not significantly change water quality in the Blackhawk- Star Point aquifer. Subsidence will occur above future underground mines, but the effects on the ground-water system cannot be quantified.
