Abstract
BACKGROUND: Many nonpublic water well users unknowingly consume contaminated groundwater containing unsafe levels of pollutants. This has important implications for more than 13 million households in the United States that rely upon nonpublic water wells for drinking, cooking, and other household uses. Although public water quality is regulated through the Safe Drinking Water Act, there are no drinking water standards for nonpublic water well quality in Kansas, nor is there an adequate public health infrastructure in place to prevent or address potential exposures to contamination. OBJECTIVES: This project was conducted to identify promising action steps that would protect Kansans relying on nonpublic water wells for drinking, cooking, and other household purposes. METHODS: The project team consisted of public health, environmental health, and legal professionals with experience working on groundwater quality issues impacting nonpublic water wells in Kansas. From 2015 through 2018, the team established and convened an advisory group; reviewed relevant state statutes and regulations, all Kansas county environmental codes, and a representative sample of 23 city water well codes; conducted an extensive review of academic literature to identify best practices; conducted dozens of key informant interviews; proposed recommendations; engaged dozens of stakeholders through a survey of these proposed recommendations; and conducted interactive webinars to identify which organizations need to lead each of the recommendations. DISCUSSION: The project team developed 18 recommendations. The recommendations are organized by survey respondents' perceptions of potential public health impact. There are very few standard practices in Kansas that ensure safe water for nonpublic household water wells. Although not all of the 18 recommendations may be applicable to other communities and states, many likely would be useful for governmental agencies, academic institutions, nonprofit organizations, and others to consider. These recommendations offer more protections for nonpublic household water well users than any resource we have found. https://doi.org/10.1289/EHP5507.
