From Los Angeles County addresses groundwater contamination and water supply reliance

How could the need for water resiliency in Los Angeles County affect Arizona's water supply?

Possible What happens if… A possibility worth considering, not a forecast.

LA County's water needs may stress Colorado River supply for Arizona Los Angeles County is prioritizing water resiliency efforts due to the presence of the largest brackish groundwater plume in the Los Angeles County Water Basin, which spans 14 miles. Since about 50% of southern Los Angeles County's water is imported from sources like the Colorado River, increased demand or pressure on the river system to meet local needs could impact overall water allocation. As Arizona relies on the Colorado River for its water supply, any heightened stress or uncertainty in the river's flow and availability could affect resource management in the state.

The facts so far

As reported. Each one links to where it comes from.

  • The largest brackish groundwater plume in the Los Angeles County Water Basin spans 14 miles.dailybreeze.com
  • About 50% of the water in southern Los Angeles County is imported from sources like the Colorado River.dailybreeze.com
  • The unpredictable future of climate change has many agencies working to build water resiliency.dailybreeze.com

Why it matters

Water security is a fundamental concern for Arizona, which relies heavily on the Colorado River system for its resource needs. Any increase in stress or uncertainty regarding the river's flow, whether due to local demand increases or broader climate pressures, directly impacts the state's ability to manage its water supply.

The event highlights a broader trend of water agencies across the basin working to build resiliency against climate change and local contamination issues. This effort by Los Angeles County, which is dealing with a massive brackish plume, underscores the systemic pressure being placed on the shared Colorado River resource.

What we don't know yet

  • How will increased water resiliency efforts in Los Angeles County specifically alter the allocation of Colorado River water?
  • What is the current projected flow rate of the Colorado River, and how does it factor into Arizona's long-term planning?

What would change this answer

A major drought declaration is issued for the Colorado River basin.The effect on Arizona would become stronger and more immediate, as reduced flow would amplify the impact of increased downstream demand.
Los Angeles County successfully implements large-scale desalination technology.The pressure on the Colorado River from LA County's needs would decrease, potentially mitigating the long-term risk to Arizona.
