Close to 30 million Americans face limited water supplies, government report finds

Nearly 30 million people are living in areas of the US with limited water supplies as the country faces growing concerns over both water availability and quality, according to a new assessment by government scientists. The US Geological Survey (USGS), which is part of the Department of the Interior, issued what it said was a first-of-its-kind report last week, with USGS Director David Applegate warning of “increasing challenges to this vital resource.” The Jan. 16 report, based on data from 2010 to 2020, examines not only water supplies but also demand patterns and water quality. The report showed that most of the country had supplies that exceeded demand during the period examined, but worrisome trends were noted.

Blog: The secret double life of America’s public lands

… People care about and use public lands for many reasons. From hunters and anglers to miners and ranchers, hikers and mountain bikers—there is something for almost everyone on public lands.  But what if you live in a city and never set foot on public lands?  Why care about them then? Not everyone hunts, fishes, mines, ranches, hikes, or bikes; but everyone, truly everyone, depends on clean water. The big secret about public lands is that they are arguably the country’s single biggest clean water provider. According to the US Forest Service, National Forests are the largest source of municipal water supply in the nation, serving over 60 million people in 3,400 communities across 33 states.  Many of the country’s largest urban areas, including Los Angeles, Portland, Denver, and Atlanta receive a significant portion of their water supply from national forests.

Millions of Americans exposed to unregulated chemicals in drinking water, study finds

Almost 100 million people in the US may be exposed to unregulated industrial chemicals in their drinking water, with communities of color especially at risk, according to a new analysis of federal monitoring data for water systems across the country. The study, published Wednesday in the journal Environmental Health Perspectives, analyzed data gathered by the US Environmental Protection Agency (EPA) from 2013 to 2015 for four types of unregulated chemicals, finding that 27% of those nearly 5,000 public water systems had detectable levels of at least one contaminant. Overall, more than 97 million US residents were served by a public water system with detectable levels of the contaminants examined in the study.

Biden-Harris administration invests over $500 million in Western water projects, with $129 million for California’s Sites Reservoir

The Biden-Harris Administration has announced a $514 million investment aimed at ensuring clean, reliable drinking water for communities across the Western United States. The Department of Interior says this funding is part of President Biden’s Investing in America agenda and will support five major water storage and conveyance projects. These initiatives are designed to address long-term water scarcity issues in the West, where communities and ecosystems have been facing increasing challenges related to water availability. A significant portion of the investment will go to California, including $129 million earmarked for the highly anticipated Sites Reservoir Project. This off-stream storage project, located on the Sacramento River system near Maxwell, California, will develop up to 1.5 million acre-feet of new water storage capacity.

Tucson approves plan for $86 million treatment facility turning wastewater into drinking water

Tucson officials are moving forward on a plan to create southern Arizona’s first water treatment facility that turns wastewater into drinking water. Tucson City Councilmembers voted to approve a proposal to use some $86 million worth of Bureau of Reclamation funding to build the new treatment facility and save Colorado River water as a result. Tucson Water Director Jon Kmiec says things began about 16 months ago, when the water utility asked the agency to fund an advanced water purification plant in Tucson’s northwest side.

EPA issues first underground injection permits for carbon sequestration in California

The U.S. Environmental Protection Agency (EPA) has announced it issued four underground injection control (UIC) Class VI well permits to Carbon TerraVault JV Storage Company, a subsidiary of California Resources Corporation, Long Beach, California. Class VI UIC wells are used to inject carbon dioxide into deep rock formations for permanent underground storage. This technology, called carbon capture and underground storage or geologic sequestration, can be used to reduce carbon dioxide emissions to the atmosphere and mitigate climate change, the EPA says. The four Class VI UIC permits are for the first permitted Class VI injection wells in California and are the first such permits issued by EPA’s Pacific Southwest Region. EPA says it has determined that the activities authorized under the Class VI UIC permits are protective of underground sources of drinking water and public health as required by the Safe Drinking Water Act.

What a new study does — and doesn’t — say about fluoride and IQ

A new report linking fluoridated drinking water to lower IQ scores in children is sure to ratchet up the debate over a practice that’s considered one of the greatest public health achievements of the 20th century. The report published Monday in JAMA Pediatrics synthesizes the results of dozens of research studies that have been released since 1989. Its overall conclusion is that the more fluoride a child is exposed to, the lower he or she tends to score on intelligence tests. The analysis was conducted for the U.S. National Toxicology Program, and it has attracted a good deal of criticism over the many years of its development. Among the biggest critiques is that it’s based on data from places where fluoride levels are far higher than the concentration recommended by the U.S. Public Health Service.

Blog: Safe Drinking Water Act turns 50

… In the previous four years, lawmakers had passed the Clean Air Act and the Clean Water Act. “Nothing is more essential to the life of every single American than clean air, pure food, and safe water,” Russell Train, then-administrator of the Environmental Protection Agency, wrote to President Gerald Ford. “The time is overdue for a Safe Drinking Water Act.” Fifty years ago, on December 16, 1974, Ford clinched a public health victory when he signed a bill that joined the pantheon of federal environmental protection laws enacted that decade. Today, the country still reaps the benefits. Most Americans are provided high-quality water from their taps.

Blog: Celebrating 50 years of the Safe Drinking Water Act

The Safe Drinking Water Act (SDWA) is celebrating 50 years! The act was signed into law in 1974 to protect public health by enforcing national standards for drinking water quality. Clean water is a basic human right and is essential to all life. Even still, American clean water supplies are becoming increasingly stretched each year—the pressures of rising population, agricultural and energy demands, and the growing effects of climate change all have a major impact on rivers and water resources. Communities across the nation are without access to safe, clean drinking water. Most recently, Hurricane Helene devastated the Southeast and left millions without clean water for weeks. If we do not embrace innovative solutions, delivering clean drinking water will become more and more difficult.

Crumbling asbestos pipes deliver drinking water

… Beneath the streets of America’s Finest City, are nearly 2,000 miles of asbestos concrete pipes carrying drinking water to thousands of homes. The pipes, composed of concrete and asbestos, once known as a “miracle mineral” for its durability, were installed after World War II until the mid-1980s, when the health hazards of asbestos became known. Decades later, the pipes are starting to crack and reach the end of their lifespan. Documents obtained by Team 10 show over the past decade, 440 water main breaks have occurred in the city’s asbestos pipes. That has some concerned asbestos fibers may now be leaching into the water supply.

Commentary: San Lucas Water Crisis: Hope for safe drinking water

Maybe you’ve received a boil-water notice after an emergency, like a flood. The water may not be safe to drink for a few hours or days – health officials recommend using bottled water. Now imagine that notice lasts for 10 years, or longer. Yes, this is the 21st century and yes, this is in the United States. But residents of the South County town of San Lucas, population 324, have been under do-not-drink orders for over a decade, ever since testing by Monterey County’s Environmental Health Bureau revealed that nitrates in the water supply exceeded levels deemed safe for human consumption. “We are requiring the use of bottled water or water from an approved source for drinking or cooking,” a July 7, 2011 notice from the Health Department read. “Research is being done to find another water source.” That research is still ongoing, with a glimmer of possibility that a solution is in sight.

Blog: Senate hearing Thursday on tribal access to clean water: it takes more than just a pile of money

The U.S. Senate Indian Affairs Committee is holding an important hearing Thursday on S. 2385, a bill to refine the tools needed to help Tribal communities gain access to something that most non-Indian communities in the western United States have long taken for granted: federally subsidized systems to deliver safe, clean drinking water to our homes. … This is the sort of bill (there’s a companion on the House side) that makes a huge amount of sense, but could easily get sidetracked in the chaos of Congress. The ideal path is for the crucial vetting to happen in a process such as Thursday’s hearing, and then to attach it to one of those omnibus things that Congress uses these days to get non-controversial stuff done. Clean water for Native communities should pretty clearly be non-controversial.

As climate hazards converge, health risks rise in California

State health officials know that extreme heat can cost lives and send people to the hospital, just like wildfire smoke. Now, new research finds that when people are exposed to both hazards simultaneously — as is increasingly the case in California — heart and respiratory crises outpace the expected sum of hospitalizations compared to when the conditions occur separately. … The study joins a growing body of research about the intersection of different climate risks. Last month, California-based think-tank the Pacific Institute published a report about how converging hazards — including wildfires, drought, flooding, sea level rise and intensifying storms — are harming access to drinking water and sanitation in California and other parts of the world. The deadly 2018 Camp fire in Butte County impacted an estimated 2,438 private wells, the report said.

Most of state’s unsafe water systems in California’s Central Valley

… A state audit from the California Water Resources Control Board released last year found that over 920,000 residents faced an increased risk of illness–including cancer, liver and kidney problems–due to consuming unsafe drinking water. A majority of these unsafe water systems are in the Central Valley. The matter has prompted community leaders to mobilize residents around water quality as politicians confront imperfect solutions for the region’s supply. Advocates point out that impacted areas, including those in Tulare County, tend to be majority Latino with low median incomes. … This year’s extreme weather has only worsened the valley’s problems. The storms that hit California at the start of this year caused stormwater tainted with farm industry fertilizer, manure and nitrates to flow into valley aquifers.

Safe Drinking Water Act

The federal Safe Drinking Water Act sets standards for drinking water quality in the United States.

Launched in 1974 and administered by the U.S. Environmental Protection Agency, the Safe Drinking Water Act oversees states, communities, and water suppliers who implement the drinking water standards at the local level.

The act’s regulations apply to every public water system in the United States but do not include private wells serving less than 25 people.

According to the EPA, there are more than 160,000 public water systems in the United States.
