Vancouver in pilot program to look for COVID-19 clues in wastewater
Vancouver, Washington, is among an increasing number of cities to use methods for testing wastewater to reveal clues to the prevalence of the COVID-19 virus in communities. Fulton Schools Professor Rolf Halden is among researchers pioneering wastewater-based epidemiology to mine sewage for indicators of human health. Halden, director of ASU’s Center for Environmental Health Engineering, and his lab team use a process called polymerase chain reaction testing to identify fragments of virus-associated RNA, the ribonucleic acid that carries the virus’s genetic information. Halden says the process provides a more accurate way to assess the spread of the coronavirus than individual medical testing.
