Common Water Contaminants in Michigan
These contaminants have been detected in various Michigan water systems
Michigan Water Regulations
Michigan Department of Environment, Great Lakes, and Energy (EGLE) oversees drinking water. Post-Flint, Michigan strengthened its Lead and Copper Rule with more protective requirements than federal standards. The state has invested heavily in testing, infrastructure replacement, and PFAS investigation.
Health Considerations
Lead remains the primary concern, particularly in communities with older infrastructure. PFAS contamination has been identified in numerous communities statewide, particularly near military bases and industrial sites. Proper corrosion control is essential for safe tap water in all Michigan communities.
Recommendations for Michigan Residents
Michigan residents should know their water utility's lead service line status and replacement plans. Request lead testing if uncertain about your home's plumbing. Consider NSF-certified lead filters, especially if you have young children. Stay informed about PFAS investigations and treatment in your area.
