Contaminants like lead in drinking water pose serious health risks, especially in older buildings with legacy plumbing systems. By participating in this project, you contribute to vital data collection efforts that can help identify contamination hotspots and promote safer water systems in your community. Join us in protecting drinking water quality through an innovative citizen science initiative! This project empowers individuals to test their tap water for harmful metals like lead using easy-to-use sampling kits. Participants collect water samples, filter them through activated carbon material, and return the filters for analysis. Our team uses advanced portable X-ray fluorescence (XRF) technology to measure metal concentrations, providing accurate results at environmentally relevant levels.
