This two-year project was conducted by the University of Minnesota for the Minnesota Department of Health starting in June 2018. The Minnesota Department of Health (MDH) contacted the University of Minnesota (UMN) requesting assistance with research and development of an action plan to address threats to safe drinking water. This work includes the identification of the regulatory, technological, behavioral, and cost barriers that need to be addressed to develop public health policies and actions to address emerging threats to Minnesota drinking water supplied by municipal systems and private wells. Additionally, the UMN team collaborated with MDH staff on the preparation of a report related to risks from lead in Minnesota drinking water. That report was published in 2019 (Minnesota Department of Health, 2019c) and has been presented to the Clean Water Council and other organizations.
