Resources for chemicals from firefighting foam and other sources

There is a group of chemicals found in toxic firefighting foam and other sources, known as PFAS. Learn more about these chemicals below.

2020 Discharge Permit Survey

Survey questions.

A spreadsheet of all survey responses.

A spreadsheet of facilities that reported storing or using AFFF or Class B firefighting foam, other PFAS chemicals, have reported PFAS passthrough, or have detectable limits of PFAS in their discharge.  

A public google folder with the supporting documents that permittees submitted with their survey. 

Several charts summarizing and grouping the data. 

Additional resources for permittees:

Map of results 

  • This 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.  To view more information about a particular facility, click on the marker. 

  • 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 responses on this spreadsheet of facilities with known or suspected PFAS presence.
