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:

The water samples were taken from private wells as part of an ongoing assessment of contamination at two potential development sites near Guilford College Road & Wendover Avenue. Though most of the residents on that street 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). This means that if the 1,4-Dioxane level was below 3.0 ppb, the lab reported nothing. The tests show Tetrachloroethene (PERC) and 1,2-Dichloroethane (a manufactured chemical used in the production of polyvinyl chloride, aka PVC) continue to exist in the groundwater.

There are two sites in the area that are being evaluated for reuse as Brownfield properties for residential development. The larger of the two sites, at 29 acres, includes the clear-cut acreage  at the corner of Guilford College and Wendover Avenue. The owners/developer is GCWA Partners LLC. The smaller of the two sites, at 5 acres, was once a septic and chemical dumping business owned by Gaither Transou.

While Transou’s dumping business closed many years ago, the latest round of results shows PFAS levels in the groundwater are increasing.

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.
