“About 60 percent of Colorado fire departments report that they have firefighting foam with synthetic chemicals known as PFAS, according to a recent survey by the Colorado Department of Public Health and Environment.

The Environmental Protection Agency has linked long-term exposure to the so-called forever chemicals to some forms of cancers and low birth weights…

PFAS chemicals came into the Colorado limelight back in 2016, when the towns of Security, Widefield and Fountain tested above the EPA health advisory recommendations for levels in drinking water. The towns have all switched to drinking water sources without the chemicals, which were eventually traced to the use of Aqueous Film Forming Foam on nearby Peterson Air Force base. Experts think the chemicals leached into the groundwater after being used at the base.

The U.S. military and manufacturers have made strides to move away from PFAS chemicals in recent years, but challenges remain.

An older generation of the firefighting foam containing PFAS has been retired from use in Colorado, and across military bases. Now, a newer version with a different chemical formula is available. Originally it was believed to not accumulate in the body, but research is emerging that shows potentially toxic health effects are concerns for many of the firefighters who use this product on the front lines…

The state government has made about $500,000 available with a priority for Colorado’s 890 drinking water districts for testing of PFAS chemicals. But fire departments will be at the back of the line behind drinking water districts to access to those funds, according to state health officials.

According to the state survey, the largest caches of the new PFAS foam is held by Suncor, the Denver Fire Department, South Metro Fire Rescue and the Pueblo Fire Department.

The departments that have large quantities of the new form on hand use it because they respond to fires at regional or municipal airports. The Federal Aviation Administration requires fire responders at some airports to have the PFAS foam on hand to ensure ‘the extinguishment of the fire for the successful evacuation of passengers and aircrew during an aircraft fire,’ according to a statement from the FAA…

The FAA is under the gun to find a replacement by Oct. 4, 2021, at which time it can no longer require the use of PFAS foam.

The agency is currently researching and evaluating replacement firefighting foams. Some airports like London-based Heathrow have switched to a fluorine-free foam that doesn’t have PFAS chemicals linked to health issues….”
