A thousand residents living in the Cape Fear region have PFAS in their bloodstream, according to the long-awaited results of a blood-sampling study performed by local researchers.
On Oct. 18, researchers from announced the results of a multi-year study that involved analyzing blood samples of 1,020 participants across three communities in the Cape Fear Region for GenX. Roughly, half of the participants in the live in the lower Cape Fear region (New Hanover and Brunswick Counties), while the other participants reside in the upper Cape Fear Basin (Fayetteville and Pittsboro), according to the report which was published online and .
One important distinction among study participants is that Fayetteville participants receive their drinking water from wells, while the other participants rely on municipal water for their water supply.
These results come even as against per - and polyfluoroalkyl substances (PFAS) manufacturers. Six of the lawsuits target aqueous film forming foam (AFFF) manufacturers and one targets the Chemours Fayetteville Works Industrial site which was the source of contamination in the lower Cape Fear.
The new study findings bolster Stein鈥檚 argument that PFAS manufacturers are harming North Carolina citizens. And with action by the EPA Administrator Michael Regan, whose agency established the , an approach to address PFAS contamination, it feels like people who are pushing back against PFAS contamination might be going on the offensive against industry instead of always playing catch-up, as they have for years.
The origin of 鈥榝orever chemicals鈥�
In the last several weeks, PFAS headlines have been a constant fixture in state and national news.
Since 2017, when GenX, a class of PFAS, were discovered in the Cape Fear River Basin downstream of Chemours Fayetteville Works site, the toxic compounds have been one of the most discussed environmental issues in North Carolina and beyond.
鈥� also referred to as 鈥渇orever chemicals,鈥� due to their persistence in the environment and the human body 鈥� have been used in the manufacturing of oil and water-resistant products, as well as products that resist heat and reduce friction.There are more than 12,000 different PFAS compounds used in products such as non-stick cookware, cosmetics, cleaning products, water-resistant clothing and textiles, and firefighting foam, along with firefighting turnout gear.
Researchers found high fluorine levels--indicating probable presence of PFAS--in about half of makeup tested.
What鈥檚 more, researchers have found evidence that suggests a link between PFAS exposure and weaker antibody responses against infections in adults and children, elevated cholesterol levels, decreased infant and fetal growth, and kidney cancer in adults.
Some key findings from the study are that while there were GenX compounds found in previous water samples in these communities, there were , said Jane Hoppin, NCSU epidemiologist and lead study researcher. GenX is the PFAS that was manufactured most widely at Fayetteville Works in recent years and that has been found in the Cape Fear River.
鈥淭he fact that we can鈥檛 measure Gen X in people鈥檚 bodies today means that we can鈥檛 measure it in you today,鈥� Hoppin told NC Health News in 2021. 鈥淚t doesn鈥檛 mean that you haven鈥檛 been exposed in the past.鈥�
What Hoppin and her team have been able to determine from all their testing is that GenX doesn鈥檛 stick around in human bodies for as long as older chemicals in the same class. But she said that doesn鈥檛 mean GenX鈥檚 passage through those bodies is benign. Like alcohol, which is ingested and then passes through the body quickly, Hoppin said GenX exposure could lead to health problems over time.
Additionally, PFOS, PFOA, PFHxS and PFNA, also referred to as legacy compounds, 鈥渨hich are found in most people in the U.S.,鈥� according to Hoppin, were present across all samples at a rate higher than the national average.
The report also said the sources of PFAS in the Cape Fear River Basin were from textile and furniture manufacturing, sludge from wastewater treatment plants used as fertilizer, the use of firefighting foam at airports and the Fayetteville Works facility.
Mounting a case against PFAS
Last month, North Carolina Attorney General Josh Stein filed two new lawsuits against the manufacturers of , a fire suppressant that contains PFAS compounds. According to the press release, the companies named in the suits are DuPont, Chemours and 3M. One suit 鈥渞elates to contamination at the Piedmont-Triad International Airport.'' The other suits target 鈥渃ontamination at Marine Corps Base Camp Lejeune and Marine Corps Air Station New River,鈥� according to the issued at the time.
Stein鈥檚 seven pending PFAS-related lawsuits signal an aggressive stance toward manufacturers who, he says, prioritize profits above all else.
鈥淚n our filing with the court, we allege that these companies that made firefighting foam knew well how dangerous it was to our first responders and our natural resources,鈥� he said. 鈥淏ut they continued to sell this product to line their pockets at the expense of our health and our drinking water. It鈥檚 wrong and unlawful, so I鈥檓 taking them to court and will fight to make sure they clean up the mess they made.鈥�
Stein's aggressive stance against corporate AFFF manufacturers seems to fall in line with EPA Administrator Michael Regan鈥檚 2021 Strategic Roadmap 鈥渢o confront PFAS contamination nationwide,鈥� according to the press release.
鈥淔or far too long, families across America 鈥� especially those in underserved communities 鈥� have suffered from PFAS in their water, their air, or in the land their children play on,鈥� Regan said. 鈥淭his comprehensive, national PFAS strategy will deliver protections to people who are hurting, by advancing bold and concrete actions that address the full lifecycle of these chemicals.鈥�
Stein talks PFAS
Stein said his previous experience suing other industries, such as opioid manufacturers, has informed his approach to the PFAS litigation.

鈥淐ompanies knew or should have known that the products they were manufacturing and selling were dangerous, and then engaged in misrepresentations or failing to warn purchasers about the risks,鈥� he said. 鈥淭hey need to be held accountable for what they did.鈥�
He said that the point of lawsuits against opioid manufacturers, for instance, is to make companies pay to clean up the messes they鈥檝e made.
鈥淲hether it's pollution, or whether it's the damage to people suffering with drug addiction, we also want to change the way [the companies] do business, so that it doesn't happen again,鈥� Stein said. That鈥檚 part of his impetus behind suing companies making the firefighting foams, too.
At this point, the original four PFAS cases have been brought into the national multinational district litigation in U.S. District Court before a federal judge.
鈥淭here's actually going to be an important trial next summer called a bellwether trial,鈥� Stein said. 鈥淗ow that case goes will be very impactful into how my litigation against these manufacturers goes. And then the two most recent cases I just filed 鈥� the one in Greensboro and the one at Camp Lejeune 鈥� will very likely be pulled into that same multidistrict litigation.鈥�
The first case Stein鈥檚 office filed against DuPont and Chemours for discharging GenX into the Cape Fear River is at the North Carolina Supreme Court on a litigation issue. He said that trial is on hold until these issues get resolved, but they were resolved in his office鈥檚 favor in a lower court.
Stein鈥檚 office worked to between Chemours and the state, where Chemours agreed to stop all discharges and emissions of PFAS, to remediate contamination in the groundwater, and to control future air emissions and reduce them by over 99 percent.
The consent order, , also forced the company to provide alternative drinking water to the homes of affected people and also pay a $12 million penalty.
鈥淭he private sector needs to be transparent about what it's doing and responsible in the decisions it makes in order to minimize the risk to the public,鈥� he said, 鈥漛ut the public sector needs to put in place clear rules that ensure the health and safety of people.鈥�
Along those lines, the EPA is getting ready to establish standards for GenX and other PFAS in drinking water that will signal to municipal water managers what are permissible levels.
鈥淚 think the federal government can really help us whether it's setting standards for water and air 鈥� or when it comes to clothing and textiles,鈥� he said. 鈥淭here are agencies out there that, I think, can play an important role setting standards,鈥� he said.
