The Navajo Nation uses the least water per capita in the US but has the country’s most expensive water. They’re right next to St. George, Utah, which uses some of the most water per capita.
Supreme Court battles (and the most corrupt SCOTUS in US history), onerous “use it or lose it” requirements for water rights, and broken promises hold back running, piped water for the reservation.
The water they do drink is often contaminated with uranium, causing cancer.
