Research from a U of T Engineering team could help support household access to safe drinking water in low and middle-income communities by adopting solar-powered ultraviolet (UV) LED illumination to treat water in Mexico’s rainwater harvesting systems. The team includes Mistelle Haughton (CivMin MASc candidate), Karlye Wong (CivMin PhD candidate) and Professor Ron Hofmann (CivMin). Together, they are among a handful of researchers focusing on the benefits of UV LEDs for water harvesting systems.
