The U.S. Environmental Protection Agency (EPA) is releasing its Analysis of Subsurface Metabolism in Groundwater Modeling for public comment. This report evaluates assumptions used in Pesticide in Water Calculator groundwater modeling, which EPA developed to estimate pesticide concentrations in vulnerable groundwater sources and is used in human dietary risk assessments.
EPA will take comments on the Analysis for 45 days, starting on April 15, 2021. You can submit comments online in docket EPA-HQ-OPP-2021-0241 at www.regulations.gov. EPA will carefully consider public input when evaluating whether changes in the methodology for estimating pesticides concentrations in groundwater are necessary.
