Most wells in Ontonagon County, Michigan obtain water from glacial lake beds or from bedrock. Deposits of glacial till and outwash also yield water to domestic wells in a few parts of the county. The lake beds supply enough water for domestic use to many wells, but more than half of the wells in the county are drilled into bedrock to obtain a satisfactory supply. Wells yielding large supplies of several hundred gallons per minute are unknown in this county. Water from most wells is hard to very hard, and many wells yield water that contains objectionable amounts of iron. Water from the deeper wells in bedrock, especially near lake superior, is generally too salty for domestic use. (knapp-usgs)
