Summary
This study implemented a survey to examine the public willingness to pay (WTP) for arsenic safe drinking water by investing in communal deep tubewells (DTW) across different arsenic-risk zones in areas of rural Bangladesh. Results showed that most survey respondents were willing to pay in principle for a communal DTW to secure access to arsenic safe drinking water; important factors that were found to influence WTP included household income, where respondents lived, awareness of water source contamination, and others. These results are consistent with other studies that have shown that WTP for arsenic safe drinking water increases as the baseline risk exposure levels increase, when controlling for other factors.

Models Used: (Not available)
Methods Used:
- Authors used a double bound discrete choice valuation elicitation approach to estimate the public willingness to pay (WTP) for arsenic safe drinking water by investing in communal deep tubewells (DTW) across different risk zones in rural Bangladesh. The authors — 1) developed an extended questionnaire with contingent valuation questions; 2) collected information about sociodemographics and other factors for households; 3) implemented survey in thirteen villages located in three districts (Comilla, Munshiganj, and Pabna) in Bangladesh following a stratified random sampling procedure for households; and 4) characterized villages at high, medium, or low risk for groundwater arsenic exposure.
