Welcome to the new EPA CompTox Chemicals Dashboard

    The new Dashboard is a complete rebuild and is replacing the CompTox Chemicals Dashboard released on July 12th 2020.
    This documentation can help get you started.

    Description: Biosolids are produced from wastewater treatment processes and can be beneficially used. The Clean Water Act (CWA) Section 405(d)(2)(C) requires the EPA to review federal biosolids standards every two years to identify additional toxic pollutants that occur in biosolids and set regulations for those pollutants if sufficient scientific evidence shows they may harm human health or the environment. The biennial review process is intended to fulfil the CWA requirement to identify additional pollutants that occur in biosolids. This list of chemicals is assembled from multiple biennial review documents containing peer-reviewed literature and the results of three national sewage sludge surveys. Regulatory limits for pollutants in biosolids are defined in 40 CFR Section 503.13, which contains numerical limits, for nine metals (i.e., arsenic, cadmium, copper, lead, mercury, molybdenum, nickel, selenium, and zinc). To view all the microbial pollutants found in biosolids see Table B-1, Chemical and Microbial Pollutants Identified in Biosolids in Biennial Review No. 8.
