Targeted National Sewage Sludge Survey Report

The Targeted National Sewage Sludge Survey is a valuable step in advancing the understanding of what is present in treated sewage sludge. The information from the survey provides important input for EPA and others to use in evaluating biosolids generated by the nation's publicly owned treatment works. It also fulfills an important commitment under the agency's four pronged strategy for pharmaceuticals and personal care products by providing the first national estimates of which pharmaceuticals, steroids and hormones may be present in sewage sludge and at what concentrations.
