This research addresses rural water scarcity in Colombia by developing a household treatment system combining filtration and solar disinfection. Using engineering models, it optimizes flow, pathogen inactivation, and sunlight exposure to ensure reliability. The approach delivers safe, simple, and sustainable water access, reducing disease and improving quality of life in underserved communities.

This research examines how microbes in drinking water recover after UV disinfection. By adding nutrients to UV-treated samples and identifying microbes through DNA sequencing, the study tracks which organisms survive, regrow, and thrive over time. The goal is to improve treatment systems and ensure safer, more stable drinking water during distribution.
