缅因州将饮用水的全氟辛烷磺酰氟限值降低到10 ppt,对全氟辛烷磺酰胺和全氟辛烷磺酸实行更严格的上限,2027-2029年生效。 Maine lowers PFAS limits in drinking water to 10 ppt, with stricter caps on PFOA and PFOS, effective 2027–2029.

缅因州已在饮用水中采用更严格的PFAS限制,与新的联邦标准保持一致,将6种PFAS化学物质的联合限制降至每万亿分之10部分,并将PFOA和PFOS的个人上限从20个百分点降至4个百分点. Maine has adopted stricter PFAS limits in drinking water, aligning with new federal standards, lowering the combined limit for six PFAS chemicals to 10 parts per trillion and setting individual caps of 4 ppt for PFOA and PFOS—down from 20 ppt. 这一规则在2027年至2029年期间有效,要求公共供水系统处理水或寻找清洁水源,遵守费用估计为5 000万美元,部分由联邦贷款供资。 The rule, effective in phases from 2027 to 2029, requires public water systems to treat water or find cleaner sources, with compliance costs estimated at $50 million, partly funded by federal loans. 超过限额的系统可能每天受到最高2 000美元的罚款。 Systems exceeding limits may face daily fines of up to $2,000. 由于健康问题,该规则将GenX和PFBS添加到受管制化学品中,而PFDA和PFHpA将不再计入上限,但仍必须监控. The rule adds GenX and PFBS to regulated chemicals due to health concerns, while PFDA and PFHpA will no longer count toward the cap but must still be monitored. 缅因州约有一半居民依赖不受管制的私人水井。 About half of Maine’s residents rely on unregulated private wells. 改革的目的是降低与癌症、免疫问题和发展问题有关的风险。 The change aims to reduce risks linked to cancer, immune issues, and developmental problems.
