公共供水系统中频繁PFAS检测的效益、成本与可负担性
Benefits, Costs, and Affordability of Frequent PFAS Testing in Public Water Systems
摘要
ABSTRACT Drinking water is a principal pathway for human exposure to per- and polyfluoroalkyl substances (PFAS), yet inconsistent PFAS testing limits effective mitigation strategies. This study estimates households’ WTP for monthly PFAS testing policy across Michigan and Ohio public water systems and compares benefits with costs. Estimated WTP is $267 per household annually. Testing costs vary by utility size and water source, but mean WTP exceeds average costs across all utilities. Fewer than 1% of survey households exceed affordability concerns from added policy costs. The findings can inform policy discussions on PFAS monitoring as the NPDWR PFAS rule is under reconsideration.

摘要 饮用水是人类暴露于全氟和多氟烷基物质（PFAS）的主要途径，但PFAS检测不一致阻碍了有效缓解策略的实施。本研究估算了密歇根州和俄亥俄州公共供水系统家庭对月度PFAS检测政策的支付意愿（WTP），并将收益与成本进行比较。估计的支付意愿为每户每年267美元。检测成本因公用事业规模和水源而异，但平均支付意愿在所有公用事业中均超过平均成本。不到1%的受访家庭因新增政策成本而超出可负担性担忧。随着NPDWR PFAS规则正在被重新审议，这些发现可为关于PFAS监测的政策讨论提供参考。
