Yeah it’s potentially a much higher cost, depending on how class-action lawsuits play out, but that study doesn’t necessarily say it’s coating the surface of the ocean. It’s diluted into the ocean itself, and because it likes to stick to foam it tends to accumulate at higher concentrations close to the surface. That study is documenting that air particles have a much higher concentration than what’s typically seen diluted in sea water, so it’s essentially congregating in the air-water interface zone.

But yes, your point is well taken that they’re facing catastrophic liability costs from a combination of past health impacts and future cleanup/removal.

Wonderful. I bet bivalve creatures are bioaccumulating tons of PFAS on the beach. Not to mention near-shore fish.

Yeah it’s pretty squarely in their wheelhouse.

Does it do the following?

• the contaminant may have an adverse effect on the health of persons;

• the contaminant is known to occur or there is a substantial likelihood that the contaminant will occur in public water systems with a frequency and at levels of public health concern; and

• in the sole judgment of the Administrator, regulation of such contaminant presents a meaningful opportunity for health risk reduction for persons served by public water systems.

If so, then:

• the Administrator shall publish maximum contaminant level goals and promulgate, by rule, national primary drinking water regulations under this subsection.

Wham, bam, thank you ma’am.
