AbstractThis NSF-BSF project will find better ways to keep water clean without using chemicals like chlorine. Most water systems use chlorine to kill germs. It is effective against many, but not all, germs. Furthermore, it leaves chemicals in the water. This project will test two types of light to clean water – ultraviolet (UV) light and antimicrobial blue light (aBL). UV light can kill germs quickly without leaving chemicals behind, but it doesn't stop germs from growing back later. aBL can damage germ
