Abstract
  • Growing concern regarding the health effects of PFAS exposure through drinking water remains an issue at the forefront of many regulatory hurdles. Current data suggests that PFAS can be the cause of many negative health effects including changes in birth weight, thyroid disease, decreased fertility, and some forms of cancer. Research also suggests that the chemical structure of PFAS, namely the carbon-fluorine bonds, makes the chemicals incredibly stable in humans and the environment. This stability has led to concerns regarding bioaccumulation and biomagnification. This paper uses a literature review to identify PFAS, what they are used for, potential exposure routes, and options for remediation of drinking water supplies. Minnesota’s response to PFAS contamination caused by 3M in the East Twin Cities Metro is used as a case study as an example for policymakers and stakeholders for mitigating a growing problem regarding persistent contaminants and doing so by working collaboratively with government, industry, and citizens. Although the response and final decision making is ongoing, this analysis indicates that Minnesota’s response encapsulated economic, social, and ecological concerns and provided clear and comprehensive options for remediation after consultation with various stakeholders and community members.
