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 ...
Politico first reported in January that EPA’s announcement would not include any plan to set a Maximum Contaminant Level (MCL) for PFAS, setting off alarms that the agency was ignoring public pleas to better regulate the substance. EPA officials on Thursday, however, pushed back on that charac...
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 ...
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 ...
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)值4 ng/L。具体来说,中国自来水中PFOS的浓度为4.3 ± 0.68 ng/L。
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...
