OPINION: The Grand Bargain of Desalination

We are told that water scarcity in the arid American West is inevitable and that the great water projects of the past century were the product of misguided hubris. Environmentalists call for Westerners to shrink their agricultural sector and ration their urban water use and, increasingly, demolish the dams and reservoirs that enabled a civilization they have now declared is unsustainable.

They are wrong. In the far West, California’s chronic water scarcity — as well as many of the threats to aquatic ecosystems in that state — are caused by mismanagement. There is plenty of water.

A Tiny Invasive Species Is a Big Threat to CA Water

When thimble-sized mussels were first detected last year in the Sacramento-San Joaquin Delta, biologists quickly rang the alarm over how severely this invasive species could threaten the state’s water supply systems.

Now, nine months after the mollusks’ appearance near Stockton, officials are in a race to rein in golden mussels as their larvae spread through the state’s network of pumps, pipes and canals, reports CalMatters’ Rachel Becker.

Their Water Taps Ran Dry When Meta Built Next Door

After Meta broke ground on a $750 million data center on the edge of Newton County, Ga., the water taps in Beverly and Jeff Morris’s home went dry.

The couple’s house, which uses well water, is 1,000 feet from Meta’s new data center. Months after construction began in 2018, the Morrises’ dishwasher, ice maker, washing machine and toilet all stopped working, said Beverly Morris, now 71. Within a year, the water pressure had slowed to a trickle. Soon, nothing came out of the bathroom and kitchen taps.

University of San Diego Students Help Remove Heavy Metals From Water

While the product may look strange, Dr. Michel Boudrias is leading a team of students at University of San Diego with what might be the future of ocean cleanup.

“It smells like a like a fish market,” undergraduate student Nikki Cardino says. “But like not one that you wanna buy any fish from!”

The Deepening Water Shortage Row Between the US and Mexico

After the thirtieth consecutive month without rain, the townsfolk of San Francisco de Conchos in the northern Mexican state of Chihuahua gather to plead for divine intervention.

On the shores of Lake Toronto, the reservoir behind the state’s most important dam – called La Boquilla, a priest leads local farmers on horseback and their families in prayer, the stony ground beneath their feet once part of the lakebed before the waters receded to today’s critically low levels.

Inside the ‘Revolutionary’ New Colorado River Proposal

In the contentious talks over how states will split the shrinking Colorado River, negotiators are reaching consensus on one point: Just go with the “natural flow.”

The concept is a somewhat simple one. Instead of negotiating future cuts across the entire seven-state region, the process would rely on recent water records — the amount of water flowing from the Colorado River headwaters in the Upper Basin to a point in Arizona marking the boundary of the Lower Basin states.

OPINION: Is California’s Water Infrastructure Ready for Climate Whiplash?

If there is anything that might constitute an overwhelming institutional consensus in California, it’s that we are experiencing climate change, and that one of the consequences will be more rain, less snow, and more so-called whiplash between very wet years and very dry years.

In an average year these days, 30 million acre feet of water flows through the Sacramento-San Joaquin Delta. But nearly half of that water comes down in the form of a melting Sierra snowpack which in an average year holds 15 million acre feet of water. This snowmelt fills the reservoirs and feeds the rivers from April through June. With climate change, so we’re told, the volume of runoff won’t change. But we’ll get almost all of it in the three months of winter. Do we have a system to handle winter flows into the delta that are twice today’s volume?

California Has a Drinking Water Problem

California’s drinking water has elevated levels of a certain contaminant found to be associated with adverse birth outcomes, causing experts to advise that safe water advisories need to be updated.

According to a nationwide study led by researchers at Columbia University, parts of the state have levels of arsenic in public drinking water higher than 5 micrograms per liter.

Helix Water District Recognized as a Certified Green Business

The Helix Water District — a public water utility serving 278,000 people in San Diego’s East County suburbs — recently received a Green Business certification from the California Green Business Network and the City of La Mesa.

This certification recognizes the district’s ongoing commitment to environmentally responsible business practices.

Every Mention of ‘Water’ in Trump’s Big Beautiful Bill

The U.S. House passed President Donald Trump’s spending bill on July 3, 2025, that includes tax cuts and cuts to Medicaid and various other programs. The bill now goes to the President to be signed. Initial estimates suggest the bill would add roughly $3 trillion to the national debt.

Mentions of water within the bill, as it pertains to the industry, are few and far between. The bill includes funding for a source water protection program and a watershed protection program.
