Leaky pipes caused Milwaukee's poorest residents to disproportionately use water resources, according to the Journal Sentinel.
Reporters utilized mean and median and cross-referenced income levels across the city. The 10 single-family households which used the most water were all low-income homes and most or all of them had leaky pipes, according to city data.
The zip codes with the highest water usage were cross-referenced with those that track income levels, and were found to contain 15 of the lowest 20 income tracks.
Use of spreadsheets were necessary for producing this report.
