Biosolids Analytical Methods and Sampling Procedures
Information on methods and sampling procedures for biosolids managers.
40 CFR Part 503, promulgated in 1993, identified allowable methods to be used for four pathogens, inorganic pollutants, and some physical and aggregate properties of biosolids. The list of allowable methods was updated in 2007 when EPA promulgated an update to 40 CFR Part 503.
