Biosolids and COVID-19 Factsheet

With the emergence of the 2019-2020 Coronavirus disease (COVID-19) pandemic, the fate of the virus in wastewater treatment operations and biosolids and potential health risks have become subjects of public interest. Therefore, IAWA, Illinois Water Environment Association, and Central States Water Environment Association worked jointly to prepare this fact sheet on the safety of biosolids with respect to COVID-19. The fact sheet is intended to be used mainly as a resource to address questions from individuals regarding biosolids and COVID-19.
