Where can I find information on biosolids? Are they safe to use on crops?


Biosolids are the nutrient-rich organic materials resulting from the treatment of sewage sludge (the name for the solid, semisolid or liquid untreated residue generated during the treatment of domestic sewage in a treatment facility). When treated and processed, sewage sludge becomes biosolids which can be safely recycled and applied as fertilizer to sustainably improve and maintain productive soils and stimulate plant growth.

Only biosolids that meet the most stringent standards spelled out in the Federal and state rules can be approved for use as a fertilizer...

Although cities decide how best to manage their biosolids, the U.S. Environmental Protection Agency (EPA) is obligated and continues to provide the public with educational information, based on the best science, about the safe recycling and disposal of biosolids.

This information is from the EPA's Biosolids home page at: http://water.epa.gov/polwaste/wastewater/treatment/biosolids/index.cfm

For information on regulation of biosolids in your state and community, contact your state environmental agency and county or municipal government.  A directory of state environmental agencies is online at http://www2.epa.gov/home/health-and-environmental-agencies-us-states-and-territories 

For information on obtaining biosolids, please contact your EPA regional or state biosolids coordinator.  A directory of coordinators is online at http://water.epa.gov/scitech/wastetech/biosolids/upload/contactlist.pdf (PDF, 10 pp., 44 KB, about PDF)
