跟进：威斯康星州州长埃弗斯批准全州首个地下水PFAS标准 限值万亿分之4
威斯康星州戴恩县麦迪逊市消息：威斯康星州州长托尼·埃弗斯（Tony Evers）10月29日宣布，他已批准该州首个可执行的地下水全氟和多氟烷基物质（PFAS）标准，将特定PFAS污染物在地下水中的限值定为万亿分之4.0（4.0 ppt）。据威斯康星州自然资源厅数据，该州95%的社区、约70%的居民依靠地下水作为饮用水来源。
本台此前报道，威斯康星州自然资源委员会10月28日一致批准这项地下水PFAS标准，规则随后送交州长与州议会审查。州长的批准使该州首个地下水PFAS标准向正式生效再进一步。威斯康星州自然资源委员会10月28日批准地下水PFAS标准：PFOA与PFOS限值定为万亿分之4
埃弗斯表示：「地下水是威斯康星州各地居民饮用水的主要来源，因此制定可执行的地下水PFAS标准至关重要。确保威斯康星人能喝上干净的水，从我上任第一天起就是首要任务，今天是这一努力中历史性的一步。」他还表示，每一位威斯康星人都应当确信，自家水龙头流出的水是安全的。
据州长办公室介绍，埃弗斯政府此前曾三度提出地下水PFAS标准，均被州自然资源委员会否决或被立法程序阻挡，最近一次受阻的规则制定于2025年2月结束；州政府随即在同月重新启动了本次规则制定程序。
就在上周，埃弗斯宣布启动两个新的补助项目：PFAS社区补助采样计划与威斯康星州PFAS私人水井检测计划，为社区检测私人水井与公共供水系统中的PFAS污染提供资金。这两个项目由1.25亿美元的PFAS信托基金出资；该基金在2023至2025两年期预算中获批，相关资金经州长签署的2025年第200号与第201号法案于今年早些时候解冻拨付，更多同类补助项目将在未来几个月内公布。
今年3月，埃弗斯已批准调整该州饮用水标准，使其与联邦基于健康的PFAS限值对齐，将饮用水中相关污染物的限值从万亿分之70降至万亿分之4.0。州长与自然资源委员会去年还批准了与联邦标准对齐的铅与铜规则修订。按新规，水务系统一旦超过新标准，必须采取纠正措施，以保护公众健康与用水安全。
州长办公室还提到，州预算委员会近期从PFAS信托基金中拨出约1000万美元，为受泰科消防产品公司（Tyco Fire Products）消防技术中心污染影响的家庭与社区提供安全、洁净的饮用水；这笔款项来自2026年6月该州与泰科公司就马里内特一带PFAS污染达成的和解。
PFAS是一类人造化学物质，数十年来被用于不粘炊具、快餐包装纸、防污喷雾和某些消防泡沫等产品。这类化学物质在制造、使用与处置过程中进入环境后难以降解，可在人体与野生动物体内累积，可能带来不良健康影响。

Follow-Up: Wisconsin Gov. Evers Approves State's First-Ever Groundwater PFAS Standards, Limit Set at 4 Parts Per Trillion
Madison, Dane County, Wisconsin — Gov. Tony Evers announced on October 29 that he has approved Wisconsin's first-ever enforceable PFAS standards for groundwater, setting the threshold for certain PFAS contaminants in groundwater at 4.0 parts per trillion (ppt). According to the Wisconsin Department of Natural Resources, 95 percent of the state's communities and about 70 percent of Wisconsin residents rely on groundwater for their drinking water supply.
The approval follows the Wisconsin Natural Resources Board's unanimous vote on October 28 to adopt the groundwater PFAS standards, after which the rule went to the governor and the Legislature for review. The governor's approval moves the state's first groundwater PFAS standards a step closer to taking effect.

"Groundwater is the primary source for Wisconsinites' drinking water across our state, which is why having enforceable groundwater standards for PFAS is so critically important. Ensuring Wisconsinites have access to clean water has been a top priority for me and my administration from the get-go, and today is a historic step in our efforts," Gov. Evers said, adding that every Wisconsinite deserves to know the water coming from their tap is safe.
According to the governor's office, the Evers Administration had previously proposed PFAS groundwater standards three separate times, each of which was rejected by the Natural Resources Board or halted by legislative barriers, with the most recent blocked effort ending in February 2025. The administration restarted the current rulemaking process that same month.
Last week, Gov. Evers announced two new grant programs, the PFAS Community Grants Sampling Program and the Wisconsin PFAS Private Well Testing Program, to help communities sample private wells and public water supplies for PFAS contamination. Both are funded by the $125 million PFAS Trust Fund approved in the 2023-25 Biennial Budget; the funding was released earlier this year under 2025 Wisconsin Acts 200 and 201, and additional grant programs will be announced in the coming months.
In March, Gov. Evers approved changes bringing the state's drinking water standards in line with federal health-based PFAS limits, reducing the threshold from 70 ppt to 4.0 ppt. The governor and the Natural Resources Board also previously approved amendments to the state's lead and copper rule to align with federal standards. Under the new rules, water systems must take corrective action if the standards are exceeded.
The governor's office also noted that the state budget committee recently released $10 million from the PFAS Trust Fund to provide safe, clean drinking water to families and communities affected by contamination from Tyco Fire Products LP's Fire Technology Center, using a payment Tyco made under a June 2026 settlement with the state over PFAS contamination in the Marinette area.
PFAS are a group of human-made chemicals used for decades in products including non-stick cookware, fast food wrappers, stain-resistant sprays and certain firefighting foams. They resist degradation in the environment and can accumulate in the bodies of humans and wildlife, where they may cause adverse health impacts.
