This study uses a 2018 stated preference survey to elicit a willingness to pay (WTP) to reduce the cancer morbidity and mortality risk from arsenic exposure through drinking water. Respondents who use a public water supply are willing to pay $35.43 per month for the risk reduction associated with lowering the maximum allowable level of arsenic in drinking water from 10 to a hypothetical level of 3 ppb; households on private wells are willing to pay $29.19. Respondents from households with children were willing to pay significantly more than respondents from households without children. We derive values of a statistical life (VSL) of $4.61 million and $3.48 million per household member, respectively, in households using municipal or well water. Shortly after the initial release of these findings, New Hampshire became the second state to set a maximum allowable level for arsenic below the national limit of 10 ppb.

评估降低新罕布什尔州市政供水中砷最大污染物水平降低癌症死亡率的风险

本研究使用 2018 年的陈述偏好调查来引出支付意愿 (WTP)，以降低因饮用水接触砷而导致的癌症发病率和死亡率风险。使用公共供水的受访者愿意每月支付 35.43 美元，以降低与将饮用水中砷的最大允许水平从 10 ppb 降低到假设水平 3 ppb 相关的风险；使用私人水井的家庭愿意支付 29.19 美元。有孩子家庭的受访者比没有孩子的家庭的受访者愿意支付更多。在使用市政或井水的家庭中，我们得出的每个家庭成员的统计寿命 (VSL) 值分别为 461 万美元和 348 万美元。在最初发布这些发现后不久，
