A Meta-analysis to Uncover the Effects of Drinking Water Pollution on Home Values

No 26-06, Working Papers from Department of Economics, Appalachian State University

Abstract: We conduct a meta-analysis of hedonic studies examining the effects of potable water contamination on home values. We assess the robustness of the results to alternative weights, test for publication bias, and estimate meta-regressions to assess price effect heterogeneity. We find that the adverse effects on home values are similar across public versus private water sources, and that declines in home values persist for more than 10 years, on average. When contamination is detected the average decrease in home values is about 4-5%; and this effect increases to a 12-13% depreciation when contamination levels exceed regulatory or health-based standards. Key Words: benefit transfer, drinking water, groundwater, hedonic, housing value, property value, meta-analysis
