Groundwater resources in McCracken County
are abundant, with fair to good water quality. All areas of the county
can produce enough water for a domestic supply from drilled wells at
reasonable depths. Multiple zones of production are common throughout
the county. The depth of uppermost production is between 30 and 200
feet. Generally, depth to adequate groundwater is less than 100 feet,
except in the uplands of southwestern McCracken County, where adequate
groundwater is obtained at depths greater than 100 feet. Water quality
generally is good, except in areas where downward percolation of surface
water and fluids from domestic sewage-disposal systems, and other sources
of domestic or industrial pollution, have contaminated the aquifer.
Groundwater sometimes contains naturally occurring iron in objectionable
amounts from the deeper zones. In some formations with slightly acidic
groundwater, a chemical reaction between the acidic groundwater and
