As a graduate student, Deborah Swackhamer made important discoveries about toxic chemicals polluting the Great Lakes; as a researcher she endured a grueling industry investigation; as a public scientist she showed how to make Minnesota’s lakes and rivers cleaner. In retirement she continues her lifelong quest to improve water quality.
