    Major Aquifers and Ground Water Quality in Ohio Ohio has abundant ground water resources, but the amount available at a given location The carbonate aquifers in western Ohio consist mainly of limestone and dolomite and may reach a thickness of 300 to 600 feet. These aquifers are capable of yielding more than 100 gpm.

  • Alkalinity and Hardness

    When limestone and dolomite dissolve in water, one half of the molecule is calcium or magnesium (the "hardness") and the other half is the carbonate (the "alkalinity"). This means that the level of water hardness and alkalinity in a place will be very similar. However, they are very separate measurements, and have very different importance.
