Taiwan Environmental Technology Water PFAS Standards

Starting in July 2027, Taiwan will begin enforcing legal limits on PFAS (Per- and Polyfluoroalkyl Substances) in public drinking water. Water suppliers will be required to monitor PFAS levels, report any exceedances, and implement appropriate treatment systems—or face fines of up to USD $20,000 (based on an exchange rate of 1:30).

This regulatory move reflects growing global health concerns over PFAS—often referred to as “forever chemicals”—and aligns Taiwan with U.S. and EU environmental standards. It also presents a valuable opportunity for U.S. water technology companies to export proven PFAS mitigation solutions.
With significant public investment in water infrastructure and a strong national focus on ESG performance, Taiwan is actively seeking advanced, reliable solutions. U.S. firms that build partnerships with local integrators, engage with the Taiwan Water Corporation, and adapt their products to local needs will be well-positioned for success.

U.S. companies with expertise in PFAS treatment, advanced filtration, monitoring technologies, and water quality solutions are encouraged to participate in Taiwan International Water Week, taking place October 29–31, 2025, in Taipei.
