The HAP aquifer system has been designated a “Sole Source Aquifer” by the US Environmental Protection Agency (USEPA), meaning that there is no alternative source of drinking water available. In 2022 a new assessment was completed for North Kingstown’s wellhead protection areas; the assessment found that the water source is at LOW to MODERATE risk of contamination.
Treatment regime

Federal UCMR5 PFAS Monitoring: Detected
This water system was tested under the federal EPA Unregulated Contaminant Monitoring Rule (UCMR5). PFAS compounds were detected below the current state-enforceable MCL.
Current MCL reflects the lowest state-enforceable limit (NYS 10 ppt for PFOA/PFOS, effective August 2020). The federal final MCL of 4 ppt for PFOA/PFOS (EPA April 2024 rule) is not enforceable until April 2029. Detections above 4 ppt but below 10 ppt are below current MCL but above the future federal limit.

Notable events from the utility's CCR
These bullet entries are the utility's own narration of operational, regulatory, or infrastructure events during the reporting period.
- In June of 2022 a Rhode Island state law was passed that set an interim standard of 20 parts per trillion (ppt) for a combination of six of the most common of these classes of compounds. Since the concentration of these compounds in one of North Kingstown’s wells was near this standard, this well was removed from service since the remaining wells have the capacity to serve the town’s needs without it.
