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.
