Move comes after Trump administration announced restrictions that could slash water supplies

Arizona has joined Nevada in its legal battle against the Trump administration’s proposed cuts to their shares of the shrinking Colorado River.

The move comes after the interior department announced restrictions this summer that could slash the water supplied to lower basin states – Arizona, California and Nevada – over the next two years depending on the river’s condition.

For-profit water corporations, federal cuts and climate crisis are ‘supercharging water rate hikes’, study co-author says

US households are paying 62% more for drinking water than they did a decade ago – outpacing inflation, grocery prices and household incomes, according to a new study.

Food & Water Watch, a Washington DC-based non-profit, analyzed 2025 billing data from the 500 largest community water systems in the US, which together serve about 155 million people, or 45% of the country’s population. The analysis compared current rates with data from a similar Food & Water Watch survey conducted in 2015. The study does not include wastewater or storm water charges, which are often billed separately from drinking water service.
