Most wells drilled
into bedrock in valley bottoms are adequate for a domestic supply, and
some wells in the alluvium of the Licking River and its main tributaries
are
adequate. Fewer than half of the wells drilled on hillsides are adequate
for domestic use, and wells on hilltops produce even less water. In
northwestern Morgan County, a few deeper wells that penetrate thick
sandstone beds of the Lee Formation produce enough water for domestic
use
and may yield enough for municipal or industrial supplies. Most water
from drilled wells is extremely hard and contains noticeable amounts
of iron. Wells that are more than 100 feet below local drainage, and
in some areas as shallow as 50 feet below drainage, may be salty. A
few springs supply enough water for domestic use, usually producing
less than 5 gallons per minute.
