Michigan proposes strong, yet incomplete PFAS protections
News
1 Jul 2019 | NRDC Expert Blog
Michigan is proposing some of the most health-protective standards in the nation for several PFAS—yet could be missing out on the opportunity to protect its citizens in the long-term. Michigan has performed the most comprehensive PFAS monitoring in the nation, and the state has begun taking steps to protect it citizens from the health risk these dangerous ‘forever’ chemicals pose. Among the monitoring results, it was discovered that over 100 of their public water systems are contaminated with PFAS—affecting approximately 1.5 million of its citizens…
