EPA published a June 14 Federal Register notice adding 109 chemicals to its list of contaminants requiring testing under its Endocrine Disruptor Screening Program (EDSP). The EDSP requires entities that produce, manufacture, use or import the listed chemicals, which may be found in drinking water sources, to perform a Tier 1 screening analyses. Tier 1 screening requires initial assays to identify substances that have the potential to act as endocrine system disruptors. Chemicals meeting the Tier 1 criteria are then required to perform Tier 2 testing to identify adverse effects and establish dose-response relationships.
EPA administers the EDSP under Congressional mandate codified in the Federal Food, Drug, and Cosmetic Act with the goal of preventing adverse health and ecological impacts of endocrine disrupting chemicals found in water sources. Additional information on the EDSP is available EPA’s EDSP webpage.
