Biosolids are solid, semi-solid, or liquid materials, resulting from treatment of domestic sewage, that have been sufficiently processed to permit these by-products to be safely land-applied. Various levels of treatment enables biosolids to be used as soil conditioners and fertilizers for agriculture, mineland reclamation, and urban landscape enhancement. The use of biosolids often evokes strong emotions due to the presence of potentially environmentally- and health-impairing constituents, such as pathogenic microorganisms, heavy metals, and anthropogenic organic compounds. The information on this site will address the benefits and concerns of biosolids products developed for agricultural, mined and urban lands.
