PFAS in the Santa Fe River Basin in Florida

Some people are interested in whether PFAS from titanium dioxide (TiO2) mines or other sources is getting into the New or Santa Fe Rivers in Florida.

For example, the new Chemours Trail Ridge South Mine southeast of Starke, Florida, appears to drain into Double Run Creek, which runs into the Santa Fe River.

We don’t know about those rivers yet, because nobody has tested them. We do have a few datapoints for a few city drinking water systems, and they’re all clean, although Newberry, just outside the Basin, is not.

No doubt it is possible to find that data in FDEP’s Oculus Document Management System, in the same way it is possible to win a jackpot in Las Vegas. If you already know about six very specific parameters, sure, Oculus will find it. Continue reading →

Health costs of firefighting foams

It’s time for the state of Georgia and the U.S. Congress to set limits, and appropriate funds for testing and remedial actions, as the evidence and lawsuits pile up about those firefighting chemicals spilled from Moody AFB and many other places.

What is the price of fire safety? As lawsuits pile up and government pressure rises, firefighting-foam makers reconsider the environmental cost of fluorosurfactants, by Marc S. Reisch, Chemical and Engineering News (c&en), JANUARY 14, 2019 | APPEARED IN VOLUME 97, ISSUE

Firefighters spray fluorine-free foam on a hydrocarbon test fire at Dallas Fort Worth Airport.

Testifying to Congress in September 2018 before it passed the legislation allowing civilian airports to use fluorine-free foams, Timothy Putnam, a 24-year civilian firefighter for the navy, said he recalled using fluorine-containing foam—in the days before scientists raised safety flags—“as a substitute for vehicle soap to wash fire department vehicles. We also used [it] to clean the fire station floors.”

Now, Putnam said, he is worried about “human impacts” of the exposure. And he didn’t accept the argument that Continue reading →
