Abstract:

After the 1993 outbreak of illness caused by Cryptosporidium in Milwaukee, the city moved forward on an $89 million upgrade of its treatment facilities with ozone filtration, the only disinfectant technology that kills Cryptosporidium. Providing safe drinking water is a quietly important issue for every city. However, in March 1993 the issue came front and center for the city of Milwaukee when Cryptosporidium�a microorganism that causes gastrointestinal illness in humans�contaminated the city drinking water, affecting an estimated 400,000 people. For some people with immune-system deficiencies, Cryptosporidiosis proved fatal. To ensure this situation would not recur, the city of Milwaukee launched a comprehensive program to upgrade the Milwaukee Water Works facilities and provide safer drinking water.
