An EWG analysis of data from state environmental agencies finds that drinking water supplies for over 15 million Americans are contaminated with MTBE, a suspected carcinogen added to gasoline that even at trace levels renders water undrinkable due to foul taste and odor.

In the first nationwide tests for chemical fire retardants in the breast milk of American women, the Environmental Working Group (EWG) found unexpectedly high levels of these little-known neurotoxic chemicals in every participant tested.

These first-ever tests of farmed salmon from U.S. grocery stores show that farmed salmon are likely the most PCB-contaminated protein source in the U.S. food supply. On average farmed salmon have 16 times the dioxin-like PCBs found in wild salmon, 4 times the levels in beef, and 3.4 times the dioxin-like PCBs found in other seafood.

Levels of a little-known class of neurotoxic chemicals found in computers, TV sets, cars and furniture are building up rapidly in key indicator species of San Francisco Bay fish, according to tests by the Environmental Working Group (EWG.)

A series of studies published beginning in the 1950s shows that DuPont has known for at least 50 years that Teflon fumes at relatively low temperatures can cause an acute illness known as polymer fume fever. In several studies DuPont recruited human volunteers and intentionally exposed them to Teflon fumes to the point of illness. The results of these studies suggest that people cooking on Teflon

Airborne soot and dust, technically known as particulate air pollution, causes or contributes to the deaths of more Californians than car accidents, murder and AIDS combined. State health officials are proposing new air pollution rules that could save or extend more than 6,500 lives a year, but the proposal faces strong and well-financed opposition from major oil companies and automakers.

The story of Anniston is a cautionary tale. Monsanto's internal documents, many of which are being posted here for the first time for the world to finally see, uncover a shocking story of corporate deception and dangerous secrets.

An emergency farm aid bill to be considered in the House of Representatives today (June 26) will provide an additional $4.6 billion in "Freedom to Farm" payments, but over half of the funds will go to just 20 congressional districts where farmers grow crops that have been subsidized since farm programs were established during the Great Depression. Those districts account for only 23 percent of

The American gun industry is in big trouble. Hunting is fading as a sport. Guns are seen by most of the general public as either weapons of crime or dangerous toys owned only by a shrinking minority of Americans. As a result, the civilian firearms market is becoming smaller and more concentrated.

High crop prices and unlimited crop insurance subsidies contributed to the loss of more than 23 million acres of grassland, shrub land and wetlands between 2008 and 2011, wiping out habitat that sustains many species of birds and other animals and threatening the diversity of North America's wildlife, new research by Environmental Working Group and Defenders of Wildlife shows.

New York regulators gave natural gas drilling industry representatives exclusive access to draft regulations for shale gas drilling as early as six weeks before they were made public, according to records obtained by the Environmental Working Group through New York's Freedom of Information Law.

A U.S. Geological Survey research team has linked oil and natural gas drilling operations to a series of recent earthquakes from Alabama to the Northern Rockies.

As a Congressional “Super Committee” presses to meet its Nov. 23 deadline to come up with a deficit reduction proposal, powerful farm state legislators and agricultural industry lobbyists have moved to hijack the process of rewriting the federal farm bill and enact a new, multi-billion dollar entitlement for the largest, most profitable farming operations. Their goal is to have the 12-member

America's farmers need a safety net, but so do the rich soil and clean water that sustain not just agriculture but the entire fabric of American society.

Hydraulic fracturing has been around for decades. But now, natural gas producers are deploying a new gas drilling method called high-volume horizontal hydraulic fracturing to release gas locked in untapped shale formations.

Since releasing our 2011 Sunscreen Guide in May, Environmental Working Group has received dozens of requests from supporters and companies asking us to add more of their favorite products.

Laboratory tests commissioned by EWG have detected hexavalent chromium, the carcinogenic “Erin Brockovich chemical,” in tap water from 31 of 35 American cities. The highest levels were in Norman, Okla.; Honolulu, Hawaii; and Riverside, Calif. In all, water samples from 25 cities contained the toxic metal at concentrations above the safe maximum recently proposed by California regulators.

After nearly 30 years of delays caused by pressure from chemicals and defense industries, the US Environmental Protection Agency (EPA) is moving forward on setting a safety limit for exposure to dioxin, a ubiquitous, highly toxic and carcinogenic chemical that people of all ages ingest daily with their food – starting at a mother's breast.

Drinking water for more than 170 million Americans contains radioactive elements at levels that may increase the risk of cancer, according to an EWG analysis of 2010 to 2015 test results from public water systems nationwide.

The known extent of the contamination of U.S. communities with PFCs – highly fluorinated toxic chemicals, also known as PFASs, that have been linked to cancer, thyroid disease, weakened immunity and other health problems – continues to expand with no end in sight. New research from EWG and Northeastern University in Boston details PFC pollution in tap water supplies for 15 million Americans in 27

The legislation would cap the amount of damages that could be sought in so-called nuisance suits brought by owners of property near concentrated animal feeding operations, or CAFOs.

TCP is just one example of the widespread contamination of drinking water from agriculture chemicals.

Exposure to PFCs has been linked to testicular and kidney cancer, thyroid disease, pregnancy-induced hypertension and preeclampsia, ulcerative colitis and high cholesterol.

In the last decade, studies by EWG and other researchers have firmly established that toxic chemicals can pass from pregnant women to fetuses through the umbilical cord, affecting children's future health and development. Now a growing body of research shows that some chemicals may alter gene function in ways that can be passed on not only to the immediate offspring, but also to grandchildren and
