The EPA recently issued an extremely positive document entitled Onsite Wastewater Treatment Systems Special Issues Fact Sheet 3—Water Softeners.* This document supports WQA’s position that the discharge of softener wastes is not harmful to septic systems. Scientific studies from the University of Wisconsin, NSF International, Ohio State University, Virginia Polytechnic Institute, and the American Society of Agricultural Engineers are referenced in the fact sheet.
The Wisconsin and NSF research studies were funded by the Water Quality Research Council (WQRC), and, gratifyingly, the three main EPA conclusion points are taken directly from those two works.
