Most Americans enjoy high quality drinking water, but contamination by agricultural pesticides and disinfection byproducts is a problem for others. Check out your water supply with EWG’s National Drinking Water Database.
Fluorine-based chemicals that can cause cancer, developmental toxicity and numerous other detrimental health effects have contaminated the drinking water of millions of Americans, and the blood of people and animals worldwide. But how did these chemicals get there – and what happens when they’re passed on to future generations?
The recent crisis in Flint, Mich., sounded the alarm on the dangers of lead contamination in drinking water. Now there’s potentially more bad news for the nation’s water supply.
Throughout most of the 20th Century, American cities and homeowners installed lead pipes and solder in their tap water delivery systems – creating a toxic legacy for all of us. And the problem isn’t likely to change soon. No matter where you live, you can use simple techniques to discover whether your tap water is polluted with lead.
Every time they drink a glass of tap water, people in the mid-Ohio River Valley of West Virginia and Ohio may be consuming unsafe amounts of an industrial chemical linked to cancer, birth defects, heart disease and other illness. More than a decade after this threat became known, government regulators have failed to set enforceable standards to ensure the water is safe – and now, new science says the danger may be much greater than either residents or regulators thought.Read More
Diesel fuels contain highly toxic chemicals, one of which is benzene, a known carcinogen. Even very small concentrations of benzene can contaminate water supplies. If benzene and other toxic chemicals seep into a community’s water, that’s a serious and possibly irreparable problem. Congress recognized diesel’s extraordinary dangers back in 2005 when it passed the federal Energy Policy Act. It exempted most oil and gas hydraulic drilling and fracturing from the Safe Drinking Water Act – but not fracking with diesel.Read More
The State of California’s proposed drinking water standard for hexavalent chromium, or chromium-6, could leave roughly 24 million residents, or more than 60 percent of the state’s population, unprotected from the known carcinogen, according to a review of the proposal by Environmental Working Group, Clean Water Action, the Natural Resources Defense Council, the Center for Public Environmental Oversight and Integrated Resource Management.Read More
Environmental Working Group applauds First Lady Michelle Obama’s campaign to get Americans to drink more water instead of soft drinks. Consuming plenty of water daily has a number of positive effects on people’s health.Read More
A new analysis by Environmental Working Group underscores the need to reform the nation’s primary land restoration program for long-term protection of wetlands, prairies and other lands that protect drinking water and wildlife habitat.Read More
The reality is that the nation’s primary prairie and wetlands protection program – the USDA’s Conservation Reserve Program (CRP) – was not designed to meet the environmental challenges being created by record prices for farm commodities. Because the majority of the land in the program is taken out of agricultural production under 10- and 15-year rental agreements with the owners, cropland that had been “restored” with grasses and trees is increasingly being plowed under to grow crops again as soon as these agreements expire. As a result, the benefits of taxpayers’ investment in these short-term agreements have proved to be fleeting.Read More
We’ve all heard of pink slime. Now, there’s green slime too.Read More
As drilling for natural gas pushes more and more into shale formations in populated areas, the problem of gas bubbling into drinking water is occurring with increasing frequency. Several homeowners have reported flaming tap water and have feared explosions. The danger is not just a theoretical one: a home in Bainbridge, Ohio, exploded in 2007 because the hydraulic fracturing and cementing of a nearby gas well was done improperly.
A new report released today by federal health officials shows that the decades-long case of drinking water contamination at Marine Corps Base Camp Lejeune in North Carolina is one of the worst on record.Read More
No matter where you live, the tap water is sure to contain some chemicals you don’t want to drink. For instance, we at Environmental Working Group recently reviewed the water quality tests of 201 big water utilities that serve 100 million Americans. As our new report shows, every single one of them was polluted with unwanted chemicals called trihalomethanes, which are linked to bladder cancer and other serious disorders.Read More
Across the nation, chlorine, added as a disinfectant to kill disease- causing microganisms in dirty source water, is reacting with rotting organic matter like sewage, manure from livestock, dead animals and fallen leaves to form toxic chemicals that are potentially harmful to people.Read More
A new Environmental Working Group analysis of 2011 water quality tests by 201 large U.S. municipal water systems that serve more than 100 million people in 43 states has determined that all are polluted with unwanted toxic chemicals called trihalomethanes. These chemicals, an unintended side effect of chlorination, elevate the risks of bladder cancer, miscarriages and other serious ills.Read More

WASHINGTON, D.C. -- Americans are not opposed to more domestic energy production, but they are unwilling to achieve it by sacrificing clean water, increased energy efficiency, and expanded wind and solar power in the process, according to a major new ORC International survey conducted for the nonprofit Civil Society Institute (CSI) and Environmental Working Group (EWG).Read More
