[Source: UA News] - A newly published report from a University of Arizona research group says biosolids, properly treated, pose little if any health risk to the public. The study, "Pathogens in Biosolids: Are They Safe?," is online in the Journal of Environmental Quality.
Ian L. Pepper, director of the NSF Water and Environmental Technology Center and a professor of soil, water and environmental science, or SWES, at the UA, led the study, a 19-year analysis tracking pathogens in biosolids from the wastewater stream in Tucson, Ariz. The study also included current data from 18 other wastewater treatment plants across the country.
