Frequently Asked Questions

Is Flint MI tap water safe to drink in 2026?

Flint tap water meets EPA federal drinking water standards and scores 43/100 (Poor) on PurityMap for 2026. PFAS forever chemicals have been detected at 4.5 ppt. An NSF-certified filter is strongly recommended. Lead levels exceed the EPA action level of 15 ppb especially in homes built before 1986. For most healthy adults the water is considered safe but point-of-use filtration adds an important layer of protection.

Does Flint MI use chlorine or chloramine for disinfection?

Flint uses chloramine as the primary disinfectant with a residual level of 2.6 ppm. Chloramine is harder to remove than free chlorine and requires a catalytic carbon or reverse osmosis filter. Standard Brita-style pitchers will NOT remove chloramine.

How hard is Flint MI water and what is the TDS level?

Flint water hardness is 5.2 grains per gallon (moderate) with a TDS of 200 ppm (fair). This level is unlikely to cause significant scale buildup in household plumbing.

Has PFAS been found in Flint MI drinking water?

Yes. PFAS forever chemicals have been detected in Flint water at approximately 4.5 ppt according to EPA UCMR5 monitoring data. A reverse osmosis or NSF P473-certified filter is the most effective residential solution.
