The long-awaited National Primary Drinking Water Regulation setting Maximum Contaminant Levels (MCLs) and MCL Goals for six per- and polyfluoroalkyl substances (PFAS) compounds in drinking water under the Safe Drinking Water Act was finalized by the U.S. Environmental Protection Agency (EPA) on A...
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 ...
Theplanincludes seven key actions that the EPA is considering to address PFAS: Establishing a Maximum Contaminant Level, known as an MCL, under the Safe Drinking Water Act (SDWA) for perfluorooctanoic acid (PFOA) and perfluoroocatane sulfonate (PFOS), two of the most preval...
Drinking Water Levels- The EPA has begun the process of developing a Maximum Contaminant Level (MCL) for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), two of the most prevalent PFAS compounds, with the goal of establishing these levels by the end of 2019. The public will ...
The EPA last year, under former administrator Scott Pruitt, began its process of determining next steps to regulate PFAS under the Safe Drinking Water Act with a national summit at EPA headquarters. A top Democrat criticized the EPA’s announcement as doing too little coming too late. ...
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 ...
喝开水,真的有用 | 分享一篇和日常生活高度相关的一篇科研文章。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(...
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...
State officials say that EPA's recently unveiled action plan to address per- and polyfluoroalkyl substances (PFAS) is disappointing and too slow, and are plowing ahead with developing their own strict standards to address heightened public concerns over the spread of chemicals in drinking water ...
EPA is weighing its rarely used emergency powers under the Safe Drinking Water Act (SDWA) to address perfluorinated compounds, a potential alternative authority the agency could use to quickly require cleanups of the chemicals at local hot spots given its reticence to craft national cleanup standards...
