In the Arizona Desert, a Farm Raising Fish Raises Questions About Water Use
- Arizona State University published a May 27 study revealing that groundwater levels have significantly dropped across the state, particularly outside the Phoenix area.
- The study attributes groundwater depletion primarily to large-scale agriculture, which consumes over 80% of water in southeastern Arizona and grows mostly water-intensive crops.
- Meanwhile, Mainstream Aquaculture operates a barramundi fish farm in Arizona that uses water efficiently by reusing effluent for crops like bermuda grass, aiming to offer a sustainable seafood alternative despite high water demand.
- James Famiglietti, the lead researcher from ASU, highlighted that Arizona currently depends more on groundwater than surface water and warned that the situation could become critical. He also indicated that managing groundwater alongside surface water might require increased involvement from federal authorities.
- Efforts to reform groundwater regulations face political resistance, with Republican lawmakers blocking rural management bills despite bipartisan negotiations, indicating ongoing challenges in addressing Arizona's worsening water crisis.

Arizona Adopts New Aquifer Water Quality Standards - The Environmental Council of the States (ECOS)
Last week, the Arizona Department of Environmental Quality (ADEQ) announced approval by the Governor’s Regulatory Review Council of new Aquifer Water Quality Standards (AWQS). These standards update the legal safety limits for pollutants in groundwater – an especially important step in Arizona, where more than 80% of residents rely on groundwater for drinking water. The updated AWQS are based on maximum contaminant levels set by U.S. EPA under t…
