"If water rates continue rising at projected amounts, the number of US households unable to afford water could triple in five years, to nearly 36 percent." That's the conclusion from a study by Elizabeth Mack, an assistant geography professor at Michigan State University, which looked at water consumption, pricing, and demographic, and socioeconomic data.
This map includes “high-risk tracts” (in black), which are areas with high concentrations of families with incomes below $32,000 that currently cannot afford water bills. The “at-risk tracts” (in gray) are areas with high concentrations of families with incomes between $32,000 and $45,120 that are at-risk of being unable to afford rising water rates in the near future.
