Tests conducted in June 2025 show PFAS groundwater concentrations in a Jamestown neighborhood rose an average of 24% over June 2024 tests. Increased concentrations were detected for TEN (10) PFAS compounds in samples taken at two residences that sit across the street, diagonally, from each other. PFAS levels were measured in unfiltered groundwater samples at one location in June 2024, and at two locations in June 2025, as shown below:
The water samples were taken from wells on Devoncourt Place as part of an ongoing assessment of contamination at two potential development sites near Guilford College Road & Wendover Avenue. Though most of the Devoncourt residents are now hooked up to the High Point Public Water System, some of the wells that remain have been used for years to draw groundwater samples for testing.
Last year’s round of tests included 1,4-Dioxane, but the lab’s detection level (3.0 ppb) was higher than the EPA’s maximum health limit (0.35), so the lab reported NOTHING, if the 1,4-Dioxane level was below 3.0 ppb. The tests show a continuing trend of concentrations of Tetrachloroethene (PERC) and 1,2-Dichloroethane (the latter is a manufactured chemical used in the production of polyvinyl chloride, aka PVC).
There are two sites in the area that are being assessed as Brownfield (contaminated) properties for reuse as residential developments. The larger of the two sites, at 29 acres, includes that clear-cut/razed forest acreage we’ve all seen at Guilford College and Wendover Avenue. The owners/developers are Barry Siegel and Willard Tucker of GCWA Partners LLC. The smaller of the two sites, at 5 acres, was once the site of a septic and chemical dumping business owned by Gaither Transou.
Transou’s dumping business closed many years ago. But this latest round of results shows that PFAS levels in the groundwater are increasing at a rapid rate. Thus far, we’ve found nothing in the North Carolina Department of Environmental Quality public records to suggest that further investigation to identify the contamination source is being done.
