Chronic PFAS Exposure in Drinking Water: Public Health Implications, Regulatory Evolution, and Preventive Risk Mitigation Strategies in the United States

Key Points

The aim is to assess the public health implications of chronic PFAS exposure and explore regulatory and prevention strategies.
Conducted a narrative review of toxicological evidence and biomonitoring data related to PFAS.
Examined regulatory evolution and detection patterns of PFAS in U.S. drinking water.
Reviewed preventive risk mitigation strategies for chronic low-dose exposure.
PFAS are widely found in U.S. drinking water systems and pose significant health risks.
Recent federal standards improve regulation but do not eliminate biological risks.
Emphasizing public health frameworks can enhance long-term health resilience against PFAS.

Abstract

Per- and polyfluoroalkyl substances (PFAS) are among the most persistent and widespread classes of synthetic chemicals detected in U.S. drinking water systems. Due to their chemical stability, environmental persistence, and bioaccumulative properties, PFAS exposure has emerged as a significant public health concern. This narrative review examines toxicological evidence, biomonitoring data, regulatory evolution, national detection patterns, and preventive mitigation strategies relevant to chronic low-dose exposure. While recent federal regulatory standards represent substantial progress, permissible limits do not equate to zero biological risk. A complementary public health framework emphasizing environmental literacy, exposure awareness, and decentralized preventive strategies may strengthen long-term national health resilience.
