Biosolids are the nutrient-rich organic product of wastewater treatment. Everyone contributes directly or indirectly to Biosolids, as both
businesses and households generate them. Following treatment, Biosolids are recycled as a fertilizer and soil conditioner in agricultural
and forestry, and in a variety of research and environmental restoration projects.
The U.S. Environmental Protection Agency's (EPA) Part 503 rule provides comprehensive requirements for the management of biosolids generated
during the process of treating municipal wastewater. The Part 503 rule creates incentives for the beneficial use of biosolids. EPA believes
that biosolids are an important resource that can, and should, be used (i.e. to condition soils and provide nutrients for agricultural,
horticultural, and forest crops and vegetation, and for reclaiming and revegetating areas disturbed by mining, construction,and waste disposal
activities). To obtain more information about the 503 rule, please visit

Biosolids contain nitrogen, phosphorus, potassium, sulfur and other nutrients needed by plants. To ensure the quality and safety of biosolids,
the physical, chemical and microbial characteristics are regularly monitored. At Am Test, we perform a complete series of tests referred to as
the "Department of Ecology Biosolids Compliance Package".
