Despite the knowledge of hazards, EPA has been a big promoter of sewage sludge use, as stated in its 1989 publication EPA’s Policy Promoting The Beneficial Use Of Sewage Sludge. EPA publicly disclosed findings of PFAS in sewage sludge/biosolids in 2001 with the release of the agency’s National Sewage Sludge Survey. Sewage sludge (biosolids) is a byproduct of sewage treatment and is used as a source of organic matter for amending soil in nonorganic agriculture and landscaping. Sewage sludge (biosolids) is prohibited from use in certified organic agriculture under the Organic Foods Production Act. Class B biosolids, used in agriculture and land reclamation, may contain pathogens, thus EPA stipulates restrictions on use.
