  • Changes in Septic Tank Effluent Due to Water Softener Use


    This study was undertaken to investigate the effect home ion-exchange water softeners may have on the performance of onsite septic tanks.

  • Reduction of Chloride to Wastewater Treatment Plants


    Chloride is a significant threat to freshwater ecosystems, and as such is addressed in wastewater discharge regulations. Chloride cannot be removed using standard wastewater treatment technology; therefore, chloride that arrives in wastewater passes through treatment plants and enters natural water bodies as treated effluent. The main goal of this project was to determine if reducing…

  • Phase 2A Report (Alkalinity, chloride, corrosivity, LSI, nitrate, nitrate-nitrite, orthophosphate, total phosphate, and sulfate):


  • Reduction of Chloride to ​Wastewater Treatment Plants


    The final report of this study is available on Madison Metropolitan Sewerage District’s (MMSD) website. The study can be used as a model approach in areas struggling with chloride discharge. The final conclusions were that on average, softener optimizations could reduce the concentration of chlorides by 27% while replacement with systems meeting 4,000 grains/lb. salt efficiency could reduce the…

  • Chloramine Fact Sheet


    Many municipal water supplies have switched from chlorine to an alternative method of disinfection to reduce the formation of trihalomethanes (THMs). Chloramine, or chloramination, is a treatment method employed by public water systems, more than one in five Americans uses drinking water treated with chloramines. Chloramines do pose a risk for hemodialysis patients and fish. Nitrosamines can…

  • Chloride Handbook


    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…
