“In June 2021, four EPA scientists, each working within the agency’s Office of Chemical Safety and
Pollution Prevention (OCSPP), publicly accused the the EPA of deliberate tampering with chemical risk assessments. The four whistleblowers made their complaints public through a group called Public Employees for Environmental Responsibility (PEER).
In a June 28 letter to the U.S. House Committee on Oversight and Reform, PEER said the four EPA scientists were providing “disturbing evidence of fraud and corruption,” involving “deliberate tampering with chemical risk assessments conducted under the Toxics Substances Control Act (TSCA), including PFAS (a.k.a. “forever chemicals”), and the deletion of potential health effects without the knowledge or consent of the human health assessors.””
