Mining-related lead pollution poses substantial health risks worldwide, especially in low- and middle-income countries. However, the public preferences regarding its health risks have not been well investigated yet, as it is not always possible to assume that the local population perceive the health risks of lead, which mostly as non-acute symptoms, such as long-term cognitive effects. This study targets a prominent case of mining-related lead contamination caused by an untreated dumpsite in Kabwe, Zambia. Though a large-scale survey of about 900 households representing the city’s population, it systematically investigates the public awareness of the lead problem among the local population and elicits the residents’ willingness to pay for reducing the pollution through remediation measures. The survey is composed of a discrete choice experiment regarding a hypothetical cleanup project financed collectively by residents and the national government. We identified that most city residents had awareness and knowledge about the local lead pollution problem and found that they had the willingness to pay for remediation of lead contamination, at a level corresponding to 113 Kwacha per month (about 6 USD per month) for a hypothetical project to reduce 50% of health risks and environmental pollution levels. This estimation of subjective willingness to pay could serve as reference information to be compared with assessments of economic burden of lead-related illnesses. Also, it points to a potential policy approach to site remediation involving the residents’ own contribution, given the local reality that initiatives for pollution containment have so far been stalled due to lack of public finance.
