The US Environmental Protection Agency (EPA) is preparing to advance several actions that could have costly implications for drinking water and wastewater treatment facilities with waste residual streams containing per- and polyfluoroalkyl substances (PFAS). These actions will create long-term cleanup liability and will increase operating costs associated with management and disposal of typical treatment wastes like coagulation sludge, lime softening sludge, biosolids, and PFAS-containing treatment media.

供水系统可能面临代价高昂的 PFAS 废物规则

美国环境保护署 (EPA) 正准备推进几项行动，这些行动可能会对含有全氟烷基物质和多氟烷基物质 (PFAS) 的废物残留流的饮用水和废水处理设施造成高昂的影响。这些行动将产生长期的清理责任，并将增加与典型处理废物（如混凝污泥、石灰软化污泥、生物固体和含 PFAS 的处理介质）的管理和处置相关的运营成本。
