This Semiannual Report to Congress reflects how the EPA OIG is achieving its mission of preventing and detecting fraud, waste, abuse, mismanagement, and misconduct related to the programs and operations of the U.S. Environmental Protection Agency and the U.S. Chemical Safety and Hazard Investigation Board. During the reporting period, April 1, 2021, through September 30, 2021, among other accomplishments, the OIG coled a federal investigation into unreliable water quality testing results, recommended how the EPA could address the adverse impact of the coronavirus pandemic on tribal drinking water systems, and determined the root causes of decline in the EPA’s federal enforcement actions.
