Perfluorinated compounds in drinking water

 
The Environmental Protection Agency (EPA) periodically requires public drinking water systems that serve more than 10,000 people to sample for contaminants of emerging concern. This is called the Unregulated Contaminant Monitoring Rule (UMCR). EPA uses the results to regulate contaminants in the future under the federal Safe Drinking Water Act.
 
In October 2015, EPA released the latest result. Data indicated that samples from public water sources tests taken in some areas detected perfluorinated compounds (also known as PFAS).
 
Drinking water sources in Colorado
Drinking water sources delivered to your tap can be treated water directly from groundwater wells, water that is blended from multiple wells or treated reservoir water, or solely treated reservoir water. 
There are several aquifers that supply Colorado with drinking water via groundwater wells.
 
Who provides my drinking water?
If you receive a water bill, then you are connected to a public drinking water system. If your water bill is included in association dues, contact the manager to determine which system provides your water. 

If you do not receive a bill, you could be served by a private well. The Colorado Department of Public Health and Environment is working with small utilities in areas that may have perfluorinated compounds to collect and test drinking water samples.
 
I have a private well. Who do I call to get more information?
Your local or county public health agency can direct you to the appropriate information.
