Certain industries create wastewater that contains unacceptable levels of chemicals or metals. These industries must pre-treat their wastewater before sending it to the community wastewater treatment facility. Pretreatment regulations were developed under the Clean Water Act. These regulations ban the discharge of any toxic substance that might… • Hinder the wastewater treatment process, • Pass through the wastewater treatment plant and contaminate the plants receiving waters, or • Concentrate in the biosolids.
