While the final rule does not change the initial monitoring timelines, it does lengthen the MCL compliance deadline, allowing affected public water facilities five years to reduce the presence of PFAS compounds in their water. The U.S. Environmental Protection Agency (EPA or Agency) announced the...
The article focuses on the Environmental Protection Agency (EPA's) new regulations establishing Maximum Contaminant Levels (MCLs) for six PFAS substances in drinking water, marking the first major update to MCLs since 2001. Topics include the specific MCLs for each PFAS contaminant, the timeline ...
该文10月发表在 ACS ES and T Water. 该文研究了影响饮用水中全氟和多氟烷基物质(PFAS)浓度的因素,并评估了人类的暴露风险。 结果显示,八氟辛酸和八氟辛烷磺酸(PFOS)是最常见的PFAS。中国自来水中的PFAS浓度显著高于英国,超过了美国环境保护署(USEPA)在2024年设定的PFOS(全氟辛烷磺酸)的最大污染物水平(MCL)...
Earlier this year, the United States Environmental Protection Agency (EPA) announced plans to propose, establish, and enforce national drinking water regulations for perfluorooctanoic acid (PFOA), perfluorooctanesulfonic acid (PFOS), and other similar substances, PFAS. These substances — which ...
MCL. This determination, however, is only the first step in the regulatory process. If EPA makes a decision to regulate PFOA and PFOS, the agency would still need to propose and promulgate a final rule that public water systems will have to meet, a process that ...
2024年4月10日,美国环保署(EPA)发布了首个具有法律效力的国家饮用水标准,以保护社区免受有害的全氟烷基和多氟烷基物质(PFAS)的影响。主要内容包括: (1)为饮用水中的6种PFAS物质建立了最大污染物水平(MCL),并确定了其基于健康的、暂不强制执行的最大污染物水平目标(MCLG),详见下表,包括PFOA、PFOS、PFHxS、PF...
In an interim response to a petition from environmentalists seeking SDWA standards for several per- and polyfluoroalkyl substances (PFAS), EPA water chief David Ross told the Ohio Environmental Council last month that while the agency is considering whether two widespread PFAS meet statutory ...
