SGWASA Engineering Project
PFAS Mitigation
Advance pilot testing and engineering design for a long-term PFAS treatment solution to meet future regulatory requirements.
Budget:
Estimated construction cost: $30 million at 90% design
Current Milestone:
SGWASA, NCDEQ, and State Grant
Advance engineering design and pilot testing for a permanent PFAS treatment solution.
Final design progressed toward the November 2026 delivery target following completion of the 90% design milestone. AquaPRS pilot testing remained underway, and the discharge permit renewal application remained under state review.
Funding:
CDM Smith
This program is SGWASA’s multi-year regulatory and treatment response to PFAS compounds detected in source water.
The EPA finalized enforceable standards for six PFAS compounds in April 2024 and established compliance deadlines that require monitoring, corrective action where needed, and public notification. In response, SGWASA has developed a phased mitigation strategy that includes pilot testing, engineering design, and long-range treatment planning.
The project has advanced through the first pilot phase, completed in December 2025, with the final report delivered in January 2026. A second pilot phase was later approved and funded.
The PFAS Advanced Water Treatment project remains on schedule, with the 90% design package scheduled for September 2026 and a SGWASA/CDM Smith review meeting set for September 30. The AquaPRS pilot startup and commissioning occurred in August, the corrosion control study final report was delivered in August, Butner special use permit coordination was completed, and the NPDES renewal application is being prepared for September submittal.

PFAS Executive Summary
Final PFAS Mitigation Report From CDM Smith
An ATSDR report, also known as a Public Health Assessment or Health Consultation, is a report by the Agency for Toxic Substances and Disease Registry summarizing an investigation of environmental contaminants and their potential health effects on a specific community.
The report provides information on health data, environmental data, and ATSDR's conclusions about the likelihood of harm to human health from exposure to site-related contaminants.
