According to a report in the Journal of the American Dietetic Association, the sodium content of water can increase to as much as 100 milligrams per litre (about a quart) after softening.
The American Heart Association states, “people on salt restricted diets should avoid home softeners or make sure the ones they install don’t use sodium.” Studies also indicate salt-softened water dissolves lead from solder in plumbing. That translates…..when bathing in salt-softened water there may be absorption of toxic lead (along with the sodium) according to the U.S. Environmental Protection Agency and the Florida Institute of Technology.
Peter Censky stated, before retiring as the Executive Director of the Water Quality Association, “Now I’m going to make some predictions about the water industry…actually, most don’t even qualify as predictions – they are already happening. Clock-timer water softeners for household use will cease to be sold. The ecology movement will drive them out of water poor states, and water rich states as well.”
