Informing private well owners

Through a partnership with the North Carolina Division of Public Health (NC DPH) in the NC Department of Health and Human Services, the UNC Research Translation Core is working to enhance DPH’s capacity to identify North Carolina populations at greatest potential risk from well water contamination and inform private well owners about potential environmental exposures and their impact on human health.  As part of this effort, SRP researchers and RTC staff mapped average concentrations of thirty-one contaminants in North Carolina groundwater, including a subset of CERCLA priority contaminants.
Each map displays the average concentration of the contaminant detected in NC private wells at the county-level, locations of National Priority List sites and permitted toxic releases, and information about how certain contaminants can enter the environment.
The site also features advanced spatiotemporal maps for arsenic and tetrachloroethylene (PCE) and detailed explanations of the mapping techniques used in this project. Detailed guidance was provided to NC DPH to enable additional mapping over time.
The website includes basic information about groundwater and the construction of private wells in North Carolina, in addition to resources for testing private well water, US EPA safe drinking water standards, and information about how to interpret well testing results.
