Pathogen Protection


Michigan Environmental Education Curriculum
Water Quality - Pollutant Sources and Impacts

Our drinking water supply and wastewater treatment plants are designed to protect against the transmission of waterborne disease. Raw drinking water is filtered to remove protozoan pathogens and then disinfected with chlorine to kill bacteria and viruses. Treated water contains some disinfectant (a residual) to protect the supply if there is a leak in the pipes that distribute the water.
