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.
First-ever nationwide assessment of chlorination byproducts in tapwater finds 137,000 U.S. pregnancies at higher risk of miscarriage, birth defectsRead More
Chlorinating tap water is a critical public health measure that saves thousands of lives each year by reducing the incidence of waterborne disease. But chlorination is no substitute for cleaning up America’s waters.Read More
Sources of drinking water for more than 7 million Californians and unknown millions of other Americans are contaminated with a chemical that disrupts child development and may cause thyroid cancer, but is unregulated by the state or federal government, according to an investigation by Environmental Working Group (EWG).Read More
On behalf of military contractor Lockheed Martin, Loma Linda University is conducting the first large-scale tests of a toxic drinking water contaminant on human subjects -- a precedent medical researchers and Environmental Working Group condemned as morally unethical and scientifically invalid.Read More
Across Ohio, small and large businesses have polluted public drinking water supplies with impunity. An Environmental Working Group analysis of Ohio EPA data and an internal, unpublished report from the Ohio Environmental Protection Agency (Ohio EPA) shows that industries have contaminated at least 54 public water supplies, but have been held responsible for contributing toward cleanup in only three cases.
n a little-noticed decision earlier this year, the EPA’s top scientific committee on children’s health declared that protections against the toxic weed killer atrazine in food and water should not be considered safe for infants and children. According to the Office of Children’s Health Protection Advisory Committee:
Atrazine, the most heavily used herbicide in the United States, is a cancer-causing weed killer applied to 50 million acres of corn each year. After it is applied each spring, it runs off cornfields and through drinking water plants into the tap water of millions of Midwestern homes.Read More
Pollutants in rivers and other source waters throughout Ohio are contaminating drinking water statewide, a citizen monitoring project has found. Tap water in a dozen Ohio communities is contaminated - at levels well above federal safety standards or guidelines - with pesticides, chlorinated compounds and other chemicals known to cause cancer, birth defects and other illnesses, according to tap water tests commissioned by the Environmental Working Group (EWG) and Ohio Citizen Action.Read More

The federal government and the states have adopted a high- cost, high-risk strategy in their drinking water programs, where consumers pay water suppliers to try to make polluted water drinkable. In spite of the vigorous efforts of drinking water providers, tap water made from dirty rivers and lakes is often host to multiple toxic chemicals, or is contaminated with the by-products of the clean-up process itself.
Mounting concern over long term health risks and the skyrocketing cost of water treatment associated with pesticide contaminated tapwater in hundreds of midwestern towns has forged an unprecedented alliance between water utilities, engineers, and chemists, and environmental protection groups.Read More
An Environmental Working Group review of nearly 200,000 water sampling records found that over two million people -- including approximately 15,000 infants under the age of four months -- drank water from 2,016 water systems that were reported to EPA for violating the nitrate standard at least once between 1986 and 1995.Read More
Nitrate in drinking water at levels greater than the Federal standard of 10 parts per million (ppm) can cause methemoglobinemia, a potentially fatal condition in infants commonly known as blue-baby syndrome. According to Dr. Burton Kross, of the University of Iowa's Center For International Rural and Environmental Health, nitrate poisoning via drinking water contamination "certainly contributes to national infant death rate statistics" (Johnson and Kross 1990). Agriculture is the primary source of nitrate contamination.Read More
