After a long time of use, Utah navy parting methods with dangerous firefighting foam

SALT LAKE CITY — U.S. navy installations throughout the globe are present process a transition from utilizing environmentally damaging firefighting foam to a brand new compound that poses much less threat to operators and the land.

“We needed to do away with all these things as a result of it is unhealthy for the atmosphere, it is unhealthy for individuals, and it is persistent,” stated Joe Bushman from Hill Air Drive Base fireplace and emergency companies. “These items, it simply lasts ceaselessly.”

Aqueous movie forming foam, or AFFF, has been used because the Sixties to snuff out troublesome fires, involving petroleum or different flammable liquids, and has been tremendous efficient. And whereas it’s credited with saving lives, the well being results on front-line staff seem like troubling.

The issue is, the froth accommodates per- and polyfluoroalkyl substances, or PFAS, a category of chemical compounds that do not readily break down in nature, and are dangerous to well being, in accordance with growing analysis.

One other examine discovered “firefighters utilizing aqueous film-forming foams have unacceptably elevated blood ranges” of per- and polyfluoroalkyl substances, which might trigger well being issues.

Rising chemical program officers issued a threat alert to the Division of Protection in 2011, warning them the firefighting foam posed dangers to human well being and the atmosphere. That alert went unheeded, as a result of it lacked endorsements from a governance council.

In July 2015, as these chemical compounds began to point out up in ingesting water across the nation, the Air Drive fireplace chief halted the near-daily assessments of the froth system, and ordered sealed models be put in on vans, so they would not require discharge for verification.

It wasn’t till 2020, nonetheless, that the Division of Protection set a purpose of transferring away from the froth by Oct. 1, 2024. At the moment, there was no accredited substitute. Lastly in September 2023, a brand new product — fluorine-free foam — was accredited to be used, and the navy started the method of distributing a whole lot of hundreds of gallons of froth focus to areas world wide.

“We began receiving product most likely on the finish of February, starting of March,” Bushman stated, proper across the time when hangars have been required to lock out their aqueous movie forming foam programs. The previous foam was faraway from all tanks, which have been then cleaned so no residue remained, and the waste was transported off-site.

The brand new foam takes one-and-a-half to 2 occasions longer to place out fires, in accordance with Bushman, however he has no issues “from the end-user standpoint.” The firefighters haven’t but acquired the inexperienced gentle to start out testing and coaching with the substitute.

Base Hearth Chief Barry Goff, for the Utah Air Nationwide Guard, stated they haven’t but acquired the brand new product, however “are excited concerning the new tech,” and are preparing by way of coaching.

“We absolutely anticipate to hit the Oct. 1 goal,” Goff stated.

The final time Hill Air Drive Base needed to deploy the aqueous movie forming foam, was when an F-35A Lightning II fighter jet crashed in October 2022. Goff has been the hearth chief since 2006, and stated there have been no emergency makes use of since he is been there.

Col. Jason Wilde, Utah Nationwide Guard land commander, stated there was one unintentional discharge in 2020 that required “all PFAS laden liquid saved till federal funding might be obtained.”

Remediation efforts

Nationwide Guard environmental program supervisor Erik Sewell stated websites testing constructive for per- and polyfluoroalkyl substances contamination have been recognized, and they’re within the “starting stage of remedial investigation.”

These websites embody acreage by the Salt Lake Metropolis Worldwide Airport, the Wendover Airfield and the E.J. Garn Aviation Advanced in West Jordan.

In 2019, 11 areas at Hill Air Drive base have been really helpful for per- and polyfluoroalkyl substances remedial investigation.

Effluent groundwater samples have been collected in December 2020, the place per- and polyfluoroalkyl substances concentrations “have been discovered to exceed the EPA Lifetime Well being Advisory,” and in a number of websites the groundwater, which is discharged instantly into the neighboring sewer districts, “might have been impacted to an extent that might create a possible hazard to human well being,” in accordance with a 2023 examine.

As a result of the worst circumstances are handled first and no ingesting water has been impacted round these areas, EPA remedial venture supervisor Rob Stites stated the remediation timeline could also be hampered by budgetary constraints, and the altering understanding of this huge chemical class.
