Frequently Asked Questions

Is there fluoride in Colorado water?

Colorado has 5,105 public water systems. 3654 have recorded fluoride violations based on EPA SDWIS data. If you are on a private well, your water is not covered by these regulations and should be tested independently.

How can I check my Colorado water for fluoride?

Search for your water system using the WaterCheck system lookup, or contact your utility and request a copy of your Consumer Confidence Report (CCR). The CCR is published annually and lists all detected contaminants, their levels, and the EPA MCLs. For private wells, contact a state-certified lab for independent testing.

The EPA Maximum Contaminant Level (MCL) for fluoride is 4 mg/L. Systems that exceed MCLs are required to notify customers and take corrective action.
