Oregon DEQ: Water Quality - Biosolids Program

The Department of Environmental Quality (DEQ) implements a statewide program that encourages the beneficial use of biosolids in a manner to protect public health and maintain or improve environmental quality. Almost all the biosolids generated by domestic wastewater treatment facilities in Oregon are applied to the land for agriculture, silviculture, and horticulture use. All wastewater facilities operate under either a National Pollutant Discharge Elimination System (NPDES) or Water Pollution Control Facility (WPCF) permit.
