Where does Flint’s water come from?
Flint’s water comes from the Gilkey Creek – Flint River watershed.
3 of the 4 EPA assessed water sources in the Gilkey Creek – Flint River watershed are in Impaired condition. These include multiple rivers and streams mostly to the east and southeast of the city.
Ideally, a water source would be rated in Good condition. Southeast of the city there is a group of Unassessed rivers and streams in Good condition. You can find more information at the How’s My Waterway link below.

Conclusion – What Can You Do?
Information about water quality can be surprising.
But there’s no reason to lose hope. There are things you can do in your household as well as things you can do at a community level.
In Your Household:
- Use Berkey filters with activated carbon to filter out 9 of the 10 contaminants in your drinking water.
- Berkey filters can also remove up to 99.99% of Lead in Flint water.
- Brita can filter 2 (and Lead depending on the filter).
- Note: We may receive a commission if you decide to purchase filters through links on this page.
- To filter out 9 of the 10 contaminants in your whole house, consider a Reverse Osmosis water filtration system for your home.
- These are more expensive than pitchers to purchase, but can be more effective.
- They have the benefit of filtering out heavy hitters like:
- Barium – health risks in water
- Haloacetic acids – chlorination byproduct*
- Hexavalent chromium – health effects
- Selenium – health risks
- Total trihalomethanes – byproduct of chlorination*
*Chlorination is an effective method of disinfecting/treating drinking water. You can then use a water filter to reduce the effects of chlorination byproducts to get the safest, cleanest water possible.
