马里兰州全州州环境厅公布饮用水全氟化学品限值提案：约150个供水系统超标、改造费约1.5亿美元、意见征集至11月30日
马里兰州全州，马里兰州环境厅10月30日在《马里兰州登记册》第53卷第22期公布饮用水全氟化学品限值提案，拟采用与2024年联邦规则相同的标准，公众意见征集至11月30日，暂未安排公开听证。
环境厅估计，全州约950个供水系统须遵守新规，其中约15%、约150个系统目前的全氟化学品浓度超过拟定标准；把这些系统改造达标约需1.5亿美元，主要来自联邦拨款，惠及约18.2万名居民。
新规覆盖全年服务的社区供水系统以及学校、办公楼等非暂住性非社区系统，不覆盖私人水井。环境厅表示，若联邦规则修订，州政府将依法同步采用更新后的规则。马里兰州总检察长此前已对联邦放宽其中四项限值的提议提出反对意见；州环境厅为期五年的全州供水系统全氟化学品调查已于2025年完成。

Maryland Environment Department Proposes PFAS Drinking Water Limits: About 150 Systems over the Standard, $150 Million in Upgrades, Comments Through November 30
Maryland — The Maryland Department of the Environment published a proposed rule on PFAS limits in drinking water in the Maryland Register (Vol. 53, Issue 22) on October 30, proposing standards identical to the 2024 federal rule. Public comments are open through November 30, and no public hearing has been scheduled.
The department estimates that about 950 water systems statewide will need to comply, and that about 15 percent of them — roughly 150 systems — currently exceed the proposed standards. Bringing those systems into compliance would cost about $150 million, mainly from federal grants, and would benefit about 182,000 residents.
The rule covers community water systems serving year-round residents and non-transient non-community systems such as schools and office buildings; it does not cover private wells. The department said that if the federal rule is amended, the state will adopt the updated rule consistent with state law. Maryland's attorney general has previously filed comments opposing the federal proposal to roll back four of the limits, and the department's five-year statewide PFAS study of public water systems was completed in 2025.
