Research Interest: Background: Unsafe drinking water remains a critical global health challenge, disproportionately affecting rural and low-resource communities. Despite global efforts, preventable waterborne illnesses continue to contribute to significant morbidity. Achieving Sustainable Development Goal 6 (SDG 6) requires scalable, sustainable, and community-driven interventions. Purpose: This project evaluated the long-term sustainability of household water filtration use, perceived health outcomes, and the effectiveness of nursing-led education among families in rural Ecuador one year following implementation. Methods: A descriptive follow-up design was utilized. Nursing faculty and students conducted in-home evaluations with 10 families who previously received water filters and structured education. Data was collected through caregiver interviews focusing on filter utilization, water practices, and gastrointestinal health outcomes. Observational field notes were analyzed to identify recurring themes and barriers. Results: Findings demonstrate sustained daily use of water filtration systems and increased caregiver confidence in maintenance practices. Families reported notable reductions in diarrheal and gastrointestinal illnesses. Nursing professionals were consistently identified as trusted sources of health education. Key barriers included limited access to replacement components and inconsistent application of filtration across all household water uses. Conclusions: Nursing-led, community-based interventions demonstrate measurable and sustained impact on health behaviors and outcomes. Ongoing engagement, culturally responsive education, and follow-up support are critical to maintaining intervention effectiveness and advancing global water security initiatives.
