Water in 70 percent of the cities in the United
States is hard enough that softening is either required or
recommended. It is estimated that approximately 30
percent of all homes in the United States use water
softeners. Water softeners, the cation exchange types
suited for residential use, exchange sodium for the
calcium and magnesium in water. The increase in sodium
levels in the softened water caused by cation exchange
softening is a direct function of the hardness level of
the untreated water. For people who use groundwater,
which has a relatively high level of naturally occurring
sodium, magnesium and calcium, the additional sodium from
cation exchange water softeners may create health hazards
for the general population and could adversely affect those
who are sensitive to salt or on low sodium diets. To
prevent potential health hazards for the general
population, no consumption of softened water by cation
exchange water softeners should be recommended. If soft
water is needed for some practical reasons, a "Separate
Water Line System" should be recommended for homeowners. / Graduation date: 1991
