This research develops biodegradable “living” water filters grown from kombucha cellulose membranes. Unlike conventional plastic filters, these biofilters can self-defend against harmful microbes and self-repair when damaged. The work aims to create affordable, sustainable, and effective water filtration systems that reduce plastic waste while improving access to clean drinking water.

This study investigates how streams retain “memory” of nitrogen pollution from past land use. Using long-term data, it identifies a 3–5 year lag between nitrogen inputs and water quality impacts. It highlights the role of forests as natural filters and emphasizes managing both current and historical pollution to protect water supplies.

Road salt, widely used for winter safety, contaminates waterways and drinking supplies by increasing sodium and chloride levels. This year-long study of Pennsylvania watersheds found consistent exceedances of EPA guidelines, posing risks to human health and aquatic ecosystems. The research highlights the need to reduce salt use and adopt more sustainable deicing practices.

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 presents a simple, low-energy method to remove and destroy PFAS “forever chemicals” from water. By chemically transforming PFAS to behave less like soap, over 98% can be separated and fully degraded, offering a scalable and environmentally friendly solution to widespread drinking water contamination.

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.
