Knowingly releasing proven carcinogens into public drinking water resources:
Publicly reported results of DuPont and Chemours studies on Gen X toxicity “contain misrepresentations and factual misstatements that tend to understate Gen X’s potential for toxicity.” DuPont data show toxic effects in animals from short-term, subchronic and long-term exposure.
Gen X exposure to rats and mice prompted incidence of cancers at levels exceeding those detected in controls in the brain, liver, adrenal glands, pancreas and testicles. Gen X posed reproductive and developmental risks to lab animals, as well as toxicity in the liver, kidneys, the hematological system, adrenal glands and stomach. DuPont animal studies demonstrated an association between GenX and effects found from other PFASs, including changes in the liver, kidney, pancreas, testicles, and the immune system.
As is very often the case when "No potentially adverse effects to humans are known at this time" cases emerge, they knew damn well what those effects could be. Researchers have a fundamental responsibility to follow-up on their laboratory findings, to make sure management doesn't try to sweep stuff like this under the rug. I realize that's easy to say, and it's not my job on the line. But we've seen this happen way too often to just accept "I did my job properly, somebody else misused my findings." Here's more evading and equivocating from DuPont:
On Wednesday, DuPont spokesman Dan Turner said company officials would respond to the new North Carolina lawsuit in court, not in the media. But he stressed that there is no evidence that chemical releases from the industrial site that DuPont built and ran for decades in Bladen County have harmed people.
“It is important to note North Carolina regulators have publicly stated that they believe the drinking water is safe,” Turner said. “Although we understand that public concern about PFCs has increased in recent years, we have no reason to believe that the discharges at issue have harmed anyone.”
Cancer clusters are notoriously difficult to pin down, especially when they are 100+ miles from the point of discharge. Those animal trials already gave DuPont a "reason to believe" those discharges would likely cause harm to people, but they also knew the people harmed could easily be lost in the crowd. This is infuriating.
