Hi! Thank you for visiting our website! This is the Environmental Technology Laboratory led by Dr. Haoran Wei, who is currently an assistant professor in the Department of Civil and Environmental Engineering at the University of Wisconsin–Madison. This lab is also affiliated with the Environmental Chemistry & Technology program. The members of our lab are a group of environmental chemists and engineers striving to protect our drinking water safety. Our research is focused on the development of rapid and easy-to-use technologies for the detection and removal of emerging contaminants in water. Although not being regulated by the US EPA Safe Drinking Water Act, the presence of emerging contaminants and their adverse impacts on human health have been increasingly reported. We hope that our research can help to sound the alarm as early as possible when emerging contamination occurs in drinking water supplies and provide solutions to reduce human exposure.
