EPA's Threshold of "High Water Burden"
Typical Customer's Annual Water and Wastewater Expenses as a percent of Minimum Wage (yearly)
Typical Customer's Annual Water and Wastewater Expenses as a percent of Median Household Income
The 4.5 percent threshold is widely used in literature (Cardoso & Wichman, 2022a; Berahzer et al., 2023; Heminger et al., 2023; Mack & Wrase, 2017). Use of the 4.5
percent threshold is largely consistent with the Hours of Labor at Minimum wage metric, which suggests a threshold of one day (8 hours), or 4.6 percent of work hours
in a month, assuming a 40-hour work week.
