n recent months, PFOA, the perfluorinated chemical formerly used to make Teflon, has been making news again. Also known as C8, because of its eight-carbon molecule, PFOA has been found in drinking water in Hoosick Falls, New York; Bennington, Vermont; Flint, Michigan; and Warrington, Pennsylvania, among many other places across the United States. Although the chemical was developed and long manufactured in the United States, it’s not just an American problem. PFOA has spread throughout the world.
As in the U.S., PFOA has leached into the water near factories in Dordrecht, Holland, and Shimizu, Japan, both of which were built and operated for many years by DuPont. Last year, the Shimizu facility and part of the Dordrecht plant became the property of DuPont’s spinoff company, Chemours. Just as it did in both New Jersey and West Virginia, DuPont tracked the PFOA levels in its workers’ blood in Holland and Japan for years, according to EPA filings and internal company documents. Many of the blood levels were high, some extremely so. In one case, in Shimizu in 2008, a worker had a blood level of 8,370 parts per billion (ppb). In Dordrecht in 2005, another worker was recorded with 11,387 ppb. The national average in the U.S., in 2004, was about 5 ppb.
Water contamination was also a problem in both locations. In Shimizu, PFOA was detected in 10 wells at the site, with the highest level of contamination measuring 1,540 ppb. Groundwater in Dordrecht, which is about an hour south of Amsterdam, was also contaminated, with 1,374 ppb of PFOA at one spot near the factory in 2014.
