North Carolina defines extraterritorial jurisdictions (ETJs) as areas outside but within 1-3 miles of a municipality. Historically, some African American communities were intentionally zoned into ETJs, in order to legally deny them municipal services, and some communities remain in these exclusionary zones. This project focuses on one such community, located in Wake County, NC. Evidence suggests that this community's domestic wells are at risk of microbial contamination. I evaluated the net present costs over 30 years of three options for protecting these households from waterborne contaminants: extending municipal water service, installing point-of-use treatment, and delivering bottled water. Net social benefits were compared to health costs of taking no action. The net social benefits of extending water service, providing point-of-use treatment and delivering bottled water are -$37,559, -$97,322 and -$620,299, respectively. By comparison, the net social benefit of no action is estimated as -$30,114. Although more costly than no action, I recommend extending community water service to the Carp Road Community as a long-term plan and delivering bottled water as a short-term option until the residents have the community water service to ensure the community has access to clean water.
