Biosolids or sewage sludge is commonly land applied in PA. The application of biosolids provides needed organic matter and nutrients for agricultural production. Federal and state standards for the beneficial use of sewage sludge regulate the quality of sewage sludge. Under the Clean Water Act EPA set pollutant limits that must be met when the sludge is land applied. Pennsylvania has adopted these standards by regulation, as well as adopting additional standards, such as standards for PCBs. Compliance with these pollutant levels is evaluated by sampling and analyzing sewage sludge before it is land applied. Proper sludge sampling techniques are the topic of this video.
