  • 2. 2010 Great Lakes Water Rate Survey
    Top ten water systems by service population from eight Midwestern states, by service population size as reported in EPA Consumer Confidence Reports
    Illinois, Indiana, Michigan*, Minnesota*, New York, Ohio, Pennsylvania, and Wisconsin (*no economic regulatory authority)
    Detailed data were mined from tariffs and websites and supplemented with personal communications.
    Nine water providers had no rate information available directly on the website
    Cautionary notes about interpretation
    Survey provides a snapshot in a very dynamic area
    Rates vary for a variety of reasons, including not limited to cost differences
    Rates alone cannot be used to draw conclusions about operational performance, including efficiency
