Abstract
Background: Nitrate contamination in groundwater disproportionately impacts agricultural Latino communities, creating a significant hazard for Latinos that rely on private wells. Private well users must conduct water testing and other well stewardship behaviors to ensure their well water is safe to drink. This study sought to identify the barriers and facilitators of private well water testing in rural, agricultural Latino communities. Methods: We conducted four focus groups with private well users, two in Spanish and two in English. We recruited 37 participants from the Lower Yakima Valley, Washington State, a rural, agricultural community with a large Latino population and elevated nitrate concentrations in groundwater. A semi-structured interview guide was developed to capture testing barriers and facilitators guided by the Risk, Attitudes, Norms, Ability, and Self-Regulation (RANAS) model. Inductive thematic analysis was conducted by two coders to identify common themes. Results: Themes emerged around barriers and facilitators to well stewardship behaviors, including well testing, treatment, and maintenance. Barriers included limited actionable information, economic limitations, lack of technical support, and challenges related to landlords and neighbors. Facilitators of well stewardship included concerns about well water contamination, knowledge of agricultural sources of contamination, do-it-yourself (DIY) home repair experience, and responsibility to protect family. Conclusions: Well stewardship programs in rural, agricultural Latino communities may want to prioritize communication that provides actionable information on well water testing, treatment, and maintenance and emphasizes the responsibility to protect family in its messaging. Additionally, programs that provide financial and technical assistance and well maintenance education that builds on DIY home repair experience may be effective in these communities.
