Common water problems in Madison
Perfluorinated chemical problems
PFOA and PFOS are artificial chemicals that were widely used until the year 2000, contaminating drinking water supplies, especially near manufacturing sites. The presence of these chemicals may result in health issues including developmental effects, cancer, liver damage, immune disorders and thyroid imbalance. Learn more about perfluorinated chemicals.
The EPA has set the limit for PFOA and PFOS in drinking water at 70 parts per trillion, but this is only an adversary level and not enforced. This means water providers are not required to test for PFOA and PFOS, and many do not.
