The Communication Resources on Chloride Handbook, developed as a WQA member benefit, is a guide to aid communications with government officials and other interested parties regarding chlorides. It is a collection of resources and information designed to support members, as well as to provide an education and solid grounding on chlorides for all interested parties, including industry members, customers, residents, legislators, regulators, water supply officials, state and local governmental units, engineering firms and political, public health and environmental leaders. Water softeners do contribute chlorides to the environment during regeneration. It is not the only source and not the largest. Holistic discussions of reducing chlorides in the environment are important. This handbook focuses on the critical role of water softeners and how optimization of water softeners can play its part in reducing chlorides.
