March 17, 2020 - GLEC was awarded a five-year $11.7 million contract from the U.S. Environmental Protection Agency’s Office of Water, Office of Science and Technology’s Health and Ecological Criteria Division (HECD). The award marks the fifth time since 1996 that GLEC was selected to provide contracting support for HECD to develop and implement science-based criteria to protect water quality and aquatic life. Work under the HECD contract includes developing chemical and biological criteria; performing effects assessments and biological evaluations for Endangered Species Act consultations; laboratory and field studies; and supporting HECD in providing assistance to states and tribes with water quality standards implementation programs. Recent HECD research on emerging contaminants has focused on understanding the effects of per- and polyfluoroalkyl substances (PFAS) on the aquatic environment and food web. GLEC is tasked with providing contractor support on current efforts to develop draft ambient water quality criteria and supporting technical documents for the protection of aquatic life and aquatic-dependent wildlife from adverse exposure to perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA), and other select PFAS substances at the national, state and site-specific (local) levels.
The GLEC team includes prominent science and engineering firms and expert consultants serving the contract’s broad technical requirements. Team member subcontractors include Midwest Biodiversity Institute, RTI International, Tetra Tech, E&C Enviroscape, and Nova Consulting. Consultants include ERG, Bryan Brooks, Tyson MacCormack, Daniel Schlenk, Syralution, and John Van Sickle
