“Nearly a dozen public water systems in North Carolina, including four that had never previously reported PFAS in their drinking water, have detected levels of the toxic compound above the EPA’s proposed maximum contaminant level. And there is no state or federal requirement that these public water systems inform their customers of the results, leaving thousands of people unaware of what’s in their drinking water.
The recent reporting was required as part of the EPA’s Unregulated Contaminant Monitoring Rule, also known as the UCMR. The EPA released the first set of data last month, representing 7% of all public water systems nationwide. The systems have until 2025 to report their findings to the agency.
These federal results do not include the roughly 50 water systems found to contain high levels of PFAS, as sampled by the state and academic researchers over the past five years.
PFAS stands for per-and polyfluoroalkyl substances. There are upward of 12,000 types of these compounds, which are used in the chemical and manufacturing industries. The compounds are often called ‘forever chemicals’ because they don’t break down in the environment, where they can linger for decades, if not hundreds of years.
In humans, exposure to even very low levels of PFAS, has been linked to multiple health problems, including thyroid and liver disorders, kidney and testicular cancers, immune system deficiencies, obesity, high cholesterol, and reproductive and fetal development problems.
In North Carolina, 57 public water systems reported their UCMR results for PFOA and PFOS, two of the compounds for which the EPA is proposing a drinking water standards.
Of those systems, 11 detected either PFOA, PFOS, or both, in their water samples at or above the proposed standard of 4 parts per trillion. That standard has not yet been formalized into a legally enforceable rule.
The list below includes the range of detection levels in parts per trillion and the number of service connections for each system. The number of service connections is lower than the number of customers. because multiple people can live in the same household.

Some public water systems do disclose their PFAS and GenX sampling results on their respective websites, among them the Town of Cary, Cape Fear Public Utility Authority, Brunswick County, and the cities of Pittsboro, Greensboro, High Point and Burlington.
But the NC Department of Environmental Quality does not require this disclosure. Of the systems on the recent UCMR list with elevated levels, most do not mention PFAS on their utilities’ webpages. Robeson County, Selma, Northampton-Lake Gaston and Lillington did not respond to NC Newsline emails asking how they communicate PFAS results to their customers.
‘DEQ has encouraged systems to communicate results to their customers,’ agency spokesman Josh Kastrinsky wrote in response to questions from NC Newsline. DEQ is also ‘providing available data to members of the public who inquire about levels in their communities.’
It’s unlikely, though, that most people know who to ask — and what to ask for.
Jamestown buys its water from High Point and Greensboro, which have detected elevated levels of PFAS in their water supply. As part of the UCMR, Jamestown reported to the EPA that PFAS in its drinking water ranged from 4 ppt to 5.9 ppt, above the proposed maximum.
Yet that information is not on the Jamestown government website. Nor is it on the DEQ website because the town didn’t participate in state sampling conducted last year. (The nonprofit Environmental Working Group has a more comprehensive map and list.)
Paul Blanchard, Jamestown’s director of public services, told NC Newsline that the town plans to update the public about PFAS via its Town Council meetings, which are recorded and broadcast on YouTube. At the next meeting, Oct. 24, the council plans to hear from their Greensboro and High Point utilities officials to provide information about treatment options.
However, it would be difficult to sift through an entire Town Council meeting to find the portion where PFAS is discussed.
Greensboro found the compounds in its drinking water as early as 2014. The NC Collaboratory also found elevated levels in Greensboro and High Point water supplies in 2019. And in 2022, Greensboro’s raw water contained PFAS nine times the proposed maximum, according to DEQ data, and High Point’s raw water exceeded three times that level.”…
