Policy Watch will live tweet the highlights of the daylong event @ncpolicywatch and @lisasorg .
Seven top EPA officials. Three division directors from the Department of Environmental Quality, plus Secretary Michael Regan. Even one of the top brass from the Centers for Disease Control and Prevention. Many of the major regulators and community watchdogs in the GenX drinking water crisis will speak at today’s public forum about perfluorinated compounds, but Chemours, the company responsible for the widespread contamination, will be conspicuous by its absence.
Hosted by the EPA, the public event begins at 10 a.m. at the Crown Ballroom, 1960 Coliseum Drive, in Fayetteville. It includes panels devoted to science, local issues and the community. A listening session for the public to provide input runs from 3 to 8 p.m.
State environmental officials had asked the EPA to hold two additional forums, one in Wilmington and the other in Greensboro, where emerging contaminants have also been detected in the water. The EPA declined, state officials said, because it lacked the time and resources.
Nonetheless, this is the first and only opportunity for North Carolinians to hear from, and speak directly to, the federal agency ultimately charged with regulating the more than 15 perfluorinated compounds, including PFAS, PFOS and GenX.
GenX has been detected in the Cape Fear River basin from Cumberland to Brunswick counties, including in river, its sediment, plus groundwater, drinking water, honey and the air. PFAS and PFOS have been founded throughout North Carolina, including Jordan Lake and Lake Michie. In the case of Jordan Lake, the contamination could be coming from the Haw River, already a problematic waterway. It is believed that Lake Michie is receiving the contaminants through the air; there are no wastewater treatment plants, industrial discharges or even sludge applications discharging into the lake.
The forum and public comments could help inform the EPA’s next steps, some of which could be finished yet this year. The EPA is scheduled to develop human health toxicity levels for GenX and recommending groundwater cleanup standards. PFOS and PFAS have been linked to high cholesterol, decreased immune response, thyroid disorders, cancer and high blood pressure in pregnant women. The EPA has set a drinking water health advisory — which is not legally enforceable — of 70 parts per trillion for PFOS and PFAS, either individually or combined.
The health effects of GenX are less clear, because there is a lack of independent, peer-reviewed data. However, North Carolina has set a health advisory goal of 140 parts per trillion. The state’s Science Advisory Board has been investigating the science behind that goal and is scheduled to recommend any changes some time this year.
Two health studies on these compounds are ongoing: Researchers Jane Hoppin, Nadine Kotlarz and Detlef Knappe of NC State, are analyzing blood and urine of about 300 volunteers in the Wilmington area. The state Department of Health and Human Services and CDC are conducting a smaller study of 30 people who live near the Chemours plant.
Meanwhile, the NC Policy Collaboratory received $5 million in this year’s state budget to conduct research on these compounds. Over the next year, more than 20 researchers, led by UNC professor Jason Surratt, will sample public water sources statewide. This will enable state regulators to know the current levels of contamination and begin monitoring for changes in those concentration.
The researchers also plan to examine how air emissions can contaminate groundwater, use modeling to predict vulnerable drinking water wells and test treatment systems that could remove the compounds.
The study will be overseen by an advisory committee of faculty members from UNC-Chapel Hill, UNC-Charlotte, UNC-Wilmington, Duke University, East Carolina University and North Carolina State University. Detlef Knappe, professor of Civil, Construction, and Environmental Engineering at NC State University, and Lee Ferguson, associate professor of Civil and Environmental Engineering at Duke University, are the co-chairs of the committee.
