YUMA, Ariz. – Yuma is 75 miles away from the nearest sea, which makes it an unlikely spot to find a water desalinization plant.
But in 1992, the Yuma Desalting Plant went online to remove salt from agricultural runoff, and increase the supply of fresh water in the Colorado River.
Severe flooding shut down the plant a few months later and it's been mothballed for almost all of its 25-year history.
Chuck Cullom, Colorado River programs manager for the Central Arizona Project, says the plant may have a new life freshening up the state's brackish groundwater that otherwise is too salty to drink.
"We think that brackish groundwater resources can increase the reliability of existing water supplies, and provide new water supplies for the state of Arizona," he states.
It's more than a drop in the bucket. Experts have identified six major sources of brackish groundwater across the state – enough to supply fresh water for 400,000 to 600,000 homes.
But getting started is expensive. The U.S. Bureau of Reclamation, which operates the Yuma plant, says getting it back online will cost $30 million to $50 million.
Brackish water is less salty than seawater, and can be treated with traditional technology at one-third the cost.
Then there's the question of what to do with the leftover brine.
Collum says the state is trying to figure out how to prevent the brine from contaminating other water sources.
"So we want to protect our high quality aquifers from salt, from making them too salty to use or requiring new 'desal' efforts," he states.
Collum sits on a special committee studying the future of desalinization in Arizona. It's expected to issue a report by the end of the year.

A Knoxville environmental group is raising concerns about a new uranium enrichment facility slated to be operated in Oak Ridge.
Unlike past sites operated by the Department of Energy's National Nuclear Security Administration, the 750,000 square-foot facility, creating more than 300 jobs, will be run by the private company Orano.
Tanvi Kardile, coordinator of the Oak Ridge Environmental Peace Alliance, said they are concerned about who will oversee safety regulations and environmental laws, as the government traditionally handled the responsibilities, including conducting environmental analyses and reports for large projects.
"How do lawsuits arise against private companies?" Kardile questioned. "There's kind of this different method of enforcement that's going to be operated and we are unsure about that, and I feel like the public should also be concerned about that, especially because all these facilities have such a direct impact on public health."
Kardile pointed out her group is already concerned with the ongoing risks tied to enriching uranium and other activities at the Y-12 National Security Complex in Oak Ridge. The uranium processing facility is estimated to cost $10.3 billion and is set to be complete in 2027. Initially, the project was expected to cost $6.5 billion and finish by 2025.
Kardile highlighted uranium poses significant radiation risks, and with multiple projects in Oak Ridge involving uranium, it would exacerbate existing concerns. Additionally, she noted besides the health risks, there is a substantial taxpayer burden with this new project.
"Taxpayer dollars has always been a big concern with all these projects," Kardile stressed. "This one is one of the biggest investments in Tennessee history, and it's a multi-billion-dollar facility, that comes with a taxpayer burden. Historically, all these nuclear sites have been delayed. Then comes cost overruns."
Kardile emphasized the importance of Tennesseans collaborating with lawmakers to find the best path to allocate their tax dollars and protect public health.

New funding from the federal Empowering Rural America program will allow the East Kentucky Power Cooperative to add more than 750 megawatts of solar energy to rural portions of Kentucky.
Co-op officials are currently seeking regulatory approval for a pair of solar installations in Fayette County, which would generate renewable energy for co-op members.
Nick Comer, external affairs manager for the co-op, said the project will cut emissions from the grid equivalent to the annual pollution from 554,000 gasoline-powered cars.
"Solar facilities will produce electricity when the sun is shining; that's no associated greenhouse gas emissions," Comer pointed out. "We estimate this will reduce carbon dioxide emissions by 3 million tons annually."
The co-op will receive additional funding in the form of tax credits on top of the $1.4 billion from the U.S. Department of Agriculture-sponsored program. The East Kentucky Power Cooperative generates electricity for 16 power distribution cooperatives across the state.
The project has generated some controversy, as some Kentucky agriculture advocates claim building the solar farms on 400 acres of prime agricultural land would not be the best use of the resource. Comer countered the installation will not harm the land long-term.
"It will have minimal impact on the land," Comer explained. "Once the solar facility has been used for 20 or 30 years and is no longer used for that, it could be returned to agricultural purposes at that point."
The funding is part of a $7.3 billion USDA program made available through the Inflation Reduction Act. The program specifically targets rural member-owned electric cooperatives in a move to eliminate greenhouse gasses produced by burning coal and natural gas contributing to climate change.

As people head to the polls tomorrow, groups are working to ensure Georgia's Black and brown communities understand the energy saving benefits of the Inflation Reduction Act.
The Payback Campaign is a public awareness initiative led by creative firm AB and supported by Georgia Interfaith Power and Light. It is helping educate congregations and communities on Inflation Reduction Act incentives, including solar energy tax credits to lower utility costs, reduce carbon emissions and build resilience.
Jay Horton, communications manager for Georgia Interfaith Power and Light, explained access to resources is especially meaningful for congregations in underserved areas.
"One of the main advantages of the Inflation Reduction Act was that congregations and faith communities, houses of worship, can now benefit from the tax credits available for solar and battery storage," Horton explained. "Especially low wealth communities."
The group helps congregations with low-cost solar assessments, connections to vetted installers, and a zero-interest loan through its Solar Wise program. To date, the initiative has completed 23 installations in Georgia, totaling 540 kilowatts and offsetting more than 3,200 metric tons of carbon emissions annually.
Horton pointed out Georgia power bills will increase by an average of $44 over two years and solar installations can help mitigate rising energy costs. Beyond saving money, he noted solar power also reduces reliance on fossil fuels, leading to cleaner air and a smaller carbon footprint. He added congregations would be able to redirect the savings into community services, all while making a positive environmental impact.
"For example, Trinity Episcopal Church in Statesboro, they had a 30-kilowatt system through the Georgia Bright program but their utility bill savings over next 20 years, $196,000, net savings of $60,000," Horton outlined. "That's equivalent to 705 tons of CO2 offset. "
He emphasized the offset is equivalent to 1.5 million miles driven in a car, or 10,000 trees planted. The Payback Campaign also highlighted how environmental and economic benefits can inform voter choices, encouraging support for leaders who prioritize clean energy initiatives.
