Detection of Per- and Polyfluoroalkyl Substances in Water

Per- and Polyfluoroalkyl Substances (PFAS) are a class of synthetic compounds known for their exceptional chemical stability. Due to their water-repellent, oil-resistant, and low-friction properties, PFAS are widely used in various surface coating applications, including textiles, paper coatings, food packaging, cookware coatings, and firefighting foams. Among the most well-known PFAS are Perfluorooctane Sulfonic Acid (PFOS) and Perfluorooctanoic Acid (PFOA).

With growing global concern over the potential health and environmental risks associated with PFAS, several PFAS compounds have been designated as Persistent Organic Pollutants (POPs) under the Stockholm Convention. In alignment with international efforts, Taiwan has also strengthened its regulatory framework. The Ministry of Environment announced drinking water quality standards for PFAS in November 2024 and revised the “Water Pollution Control Measures and Testing Reporting Management Regulations” in January 2025, formally including PFAS as a regulated category for water pollution control.

As an accredited testing laboratory recognized by the Ministry of Environment, SGS is equipped to analyze multiple PFAS indicators in water, including PFOS and PFOA. We offer professional analytical services to help enterprises and organizations comply with regulatory requirements, enhance water quality management, and strengthen environmental risk control mechanisms.
