Leaching of Metals from Household Plumbing Materials: Study of the Impact of Home Water SoftenersThe results demonstrated that there is no link between softened water and corrosion. This U.S. Environmental Protection Agency Study, funded by WQRF, provided scientific support that ion exchange water softening does not affect the corrosivity of water.
