FAQ

Frequently asked questions about Michigan's water

Is Michigan's tap water safe to drink?

Michigan's water quality varies by city. The statewide average grade is B+ (81/100). 86% of cities scored an A or B, while 7% received a D or F. Check your specific city for detailed results.

Which Michigan cities have the best water quality?

The top-rated cities are Commerce Township (A+), Frankenmuth (A+), Bridgeport (A+). These cities scored highest based on violation history, lead levels, PFAS contamination, and regulatory compliance.

Which Michigan cities have the worst water quality?

The lowest-rated cities are Grand Blanc (F), Kalamazoo (F), Marquette (F). We recommend residents in these areas consider water filtration and review their city's specific contaminant data.

How many Michigan cities have PFAS in their water?

76 out of 520 cities tested positive for PFAS "forever chemicals" (15%). 8 cities exceed the 2024 EPA maximum contaminant levels. Reverse osmosis or activated carbon filters can help reduce PFAS exposure.

Do any Michigan cities have dangerous lead levels?

13 cities exceed the EPA lead action level of 15 ppb. Lead contamination typically comes from aging pipes and lead service lines rather than the water source itself. An NSF 53-certified filter can effectively remove lead from tap water.
