Robert W. Golledge Jr. spent 13 years at the Massachusetts Department of Environmental Protection including three as commissioner before being named Secretary of Environmental Affairs in August.
Golledge spent the early part of his career with the Peace Corps in Costa Rica.
"I am honored to be offered the opportunity to serve with the Peace Corps again," he said in a statement. "I am also very fortunate to have had the chance to work with so many dedicated and professional people during my tenure at the (Executive Office of Environmental Affairs) and (Department of Environmental Protection)."
During his tenure with the state environmental agencies, Massachusetts became the first state to establish drinking water standards for perchlorate, a chemical that can affect sensitive populations. The state also began using aerial enforcement to help monitor wetlands and catch violations.
Golledge will begin training in Washington early next year before taking up his new post.
