Unregulated, 'Dark Waters' chemicals persist in cookware, clothing, sickening people, environment

Comedian and social critic John Oliver's latest top story on HBO's Last Night concerned PFAS, the artificial chemical substances behind non-stick coatings on cookware and incorporated into food wrappings and textiles, known to be highly dangerous to human health.


The stuff persists, Oliver explained, in new, unregulated, and unlabeled formulations, despite a horrific track record of illness, from obesity to terminal cancer, and environmental damage.  Oliver related recent history by quoting parts of the landmark New York Times Magazine feature by Nathaniel Rich in 2016, "The Lawyer Who Became Dupont's Worst Nightmare."  That piece inspired the unsettling 2019 feature film Dark Waters.  Oliver also excerpted a 2018 documentary, The Devil We Know.

PFAS, a "forever chemical" that persists in the environment for thousands of years, is now in the blood of virtually all Americans.  Food wrappings and clothing are our greatest risk, Oliver explained, and there is no labeling to warn us.

I just caught this on a spot-check. Adiós, sartén.
In my household, since Dark Waters brought the issue to our attention, we've exclusively adopted silicone tools to use with non-stick-coated cookware.  And at the first sign of scratching, out goes the pan or pot: a pricey luxury we are lucky to be able to afford, while we only worsen the environmental problem.  We have lately been investigating non-stick alternatives, and Oliver has ignited the gas burner under us to get moving on that.

PFAS is in the water supply, too, sometimes in alarming doses, 70 parts per trillion (ppt) being the EPA's recommended maximum concentration in drinking water.  Oliver pointed viewers to a "PFAS Contamination" interactive map created by the NGO Environmental Working Group.  The map is intriguing and informative to play around with, as it compiles water quality data from around the country.

But the most frightening takeaway from the map is the data it does not contain.  Data collection is hit or miss.  The closest results to me in East Bay Rhode Island come from a small school serving only 40 persons (4 ppt), a Massachusetts water district serving 13,627 persons (20 ppt), and the Pawtucket (R.I.) water system, serving 99,200 persons and reporting a PFAS excess at 74 ppt.

My local water authority, Bristol County (BCWA), says my water rather comes from Providence, which is not on the EWG data map, and where water quality reports appear to be missing.  It further undermines my confidence in the system that BCWA has been wanting to build a pipeline to Pawtucket, which offers, BCWA says, "another source of excellent quality water."

At last, Europe is moving ahead with regulation; I hope that will spur the United States to follow suit.

[UPDATE, 17 Oct. 2021:  Providence Water sent me a copy of the 2020 Water Quality Report in the mail. As anticipated by Oliver, there is no mention in the report of PFAS.]
