A former Biden administration official who led water protection efforts along the U.S.-Mexico border is now working at a major engineering firm. Maria-Elena Giner, the former U.S. commissioner of the International Boundary and Water Commission, joined Black & Veatch last week as a portfolio leader. She is on the firm’s water resources and community planning team, working with federal agencies, state and local governments, utilities and private companies, including tech firms. Giner said her new role will focus on environmental and infrastructure challenges affecting the water sector.
