EPA defines the five categories of environmental impact mitigation. For an underground gold mine in Nevada, there are two aquifers: one closer to the surface, which has good water quality (drinkable) and the other, which is saline and deeper. The conceptual mine plan involves drawing 1,200 acre-ft of water from the aquifer nearer to the surface, annually. The water use impacts are of concern in this dry environment. For the water use, list one example for each of the mitigation categories.
