Hard Water May Protect Against Heart Disease

As most of our customers know from reading our Annual Newsletter, our water comes naturally from deep wells and has a relatively high hardness factor.  Hardness is determined primarily by the amount of calcium and magnesium in the water.  It is expressed in milligrams per liter of calcium carbonate (or often as grains per gallon of calcium carbonate).  1.0 gr/gal = 17.1 mg/l. The water from Great Oaks Water Company wells has a hardness of about 18 gr/gal.  Now we learn that there may be hidden benefits in this aspect of our water.
