EPA is extending the public comment period on its Analysis of Subsurface Metabolism in Groundwater Modeling to give the public and stakeholders more time to review and comment.
The current comment period was set to close on June 6, 2021, and EPA is extending the comment period for an additional 30 days. Comments can be submitted through July 6, 2021, to the docket EPA-HQ-OPP-2021-0241 at www.regulations.gov.
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 carefully consider public input when evaluating whether changes in the methodology for estimating pesticides concentrations in groundwater are necessary.
