Key takeaway The communities all receive water treated by the Great Lakes Water Authority, or GLWA.
Why this matters in The Detroit
The fact that 25 Metro Detroit communities have exceeded Michigan's lead action level for drinking water since 2018 raises concerns about the effectiveness of the Great Lakes Water Authority's corrosion control measures. With the Michigan Department of Environment, Great Lakes, and Energy regulating these measures, it is crucial that the state takes a more proactive approach to addressing lead contamination. The upcoming GLWA Board of Directors meeting on July 22 presents an opportunity for community members to voice their concerns and demand action. As one in four Metro Detroit households may be drinking water from lead pipes, the need for widespread distribution of water filters and accelerated lead service line replacement is pressing. Local residents can take immediate steps to protect themselves by using certified lead-reducing drinking water filters, but a comprehensive solution requires collective action and accountability from regulators and water authorities.
