This project involved assisting the Office of Sustainability and the City of Morris to understand the use of softeners and the amount of chloride put into the city’s waste water treatment plant. The Minnesota Pollution Control Agency recently presented new regulations for chloride levels being discharged into rivers from municipal waste water treatment plants. The students measured current chloride levels and estimated the amount of chloride that would be discharged if the community switched to high-efficiency softeners. This information is being used to inform the community on whether the city should invest in a municipal water softening system.
