Projects and programs addressing chemicals from firefighting foam and other sources

The department is committed to protecting human health and the environment. We are taking actions to reduce exposure to PFAS chemicals. More information can be found on our FAQ (en español).


Vulnerability Map

This project will lead to the development of a statewide map to help us determine where we should prioritize PFAS sampling and collect firefighting foam. This map will use many sources of data to determine possible water contamination and who might be at risk. It will consider potential burdens on disproportionately impacted communities.


CO SCOPE is the Colorado Study on Community Outcomes from PFAS Exposure. Communities in Southeast El Paso County, Colorado were exposed to PFAS chemicals in their drinking water as a result of firefighting foam use at Peterson Air Force Base. A team is studying how drinking water that contains these chemicals may harm health. This study is part of a nationwide, multi-site study funded by the Agency for Toxic Substances and Disease Registry (ATSDR).

PFAS Grant Program

This program provides funding opportunities for sampling efforts to test groundwater and surface water, water treatment infrastructure, and emergency assistance for communities and water systems affected by these chemicals. We plan to begin the grant program in the fall of 2021.

Takeback Program

This program allows us to purchase and store firefighting foam containing these chemicals until we can safely dispose of it. We plan to begin this program in the fall of 2021.


CDC/ATSDR Exposure Assessment

The Centers for Disease Control and Prevention (CDC) and ATSDR completed an exposure assessment of people living near Peterson Air Force Base in El Paso County, Colorado.

A team tested 346 people, including 28 children. Eighteen people also provided household samples, including tap water. 

Initial results showed three chemicals (PFHxS, PFOS, and PFOA) in blood were above national averages. Results for four other chemicals (PFNA, MeFOSAA, PFUnA, and PFDA) were similar to or below national averages. Urine sample results showed very low concentrations of these chemicals.

Levels of PFAS chemicals in all 18 tap water samples were below all federal and applicable state guidelines for PFAS chemicals in drinking water. 


2020 Sampling Project

We sampled 400 water systems, 15 firefighting districts, 152 groundwater sources, and 71 surface water sources. None of the treated drinking water tested above EPA’s health advisory level. Some of the groundwater and surface water sources tested above that level.

We offered free testing to public drinking water systems and fire districts with wells. We took samples from:

  • Treated drinking water from public water systems.
  • Groundwater and surface water sources used for drinking water.
  • Wells serving fire districts.

Samples were then tested for these chemicals to help communities learn about potential risks. We encourage water systems to share their results with their customers.

We are currently following the EPA health advisory. If testing shows levels above the health advisory, we will work with the water system to notify the public and reduce exposure.

This dashboard only reflects public water systems that signed up for the 2020 Sampling Project. Systems without test results on this dashboard may have already sampled for these chemicals or plan on doing their own sampling.

We encourage systems to contact us if they have sampled for PFAS recently or plan to sample soon.

2020 Discharge Permit Survey

To better understand potential risks of these chemicals making their way into Colorado waters, we required facilities with discharge-related permits to respond to a survey in 2020. 193 facilities self-reported a known or suspected presence of these chemicals.

Learn more

We surveyed facilities permitted to release treated wastewater, water used for manufacturing, and other similar activities into local waterways. The survey asked about the use and storage of certain products containing these chemicals.

The results help us better understand the use of these chemicals and risks to state waters. We can also determine if specific permits may need PFAS monitoring.

The map shows the locations of facilities that reported on the PFAS survey that they: use or store AFFF or Class B firefighting foam or other PFAS-containing materials; are within proximity to where AFFF is likely used; and/or have potential PFAS passing through their wastewater treatment plant. 

  • The locations of the facilities are based on the latitude and longitude coordinates listed on their department permits. THIS MAY NOT REFLECT THE ACTUAL LOCATION OF THE FACILITY OR PERMIT LOCATION. For example, the municipal storm sewer permit usually covers the entire city area. The latitude and longitude may reflect the center of that area or is located near the permitted area.

Note: ArcGIS software has a character limit on what can be displayed. Use this guide to understand what each row means when selecting a point to view more information about it. The character limit cuts off some of the words in longer responses submitted for the survey, but you can find the full response on this spreadsheet of facilities with known or suspected PFAS presence.
