  • The Need for Chemical Reform in the United States

    The U. S. chemicals management system is broken. It fails to protect human health from hazardous chemicals adequately because it lacks mandatory safety requirements before a chemical can gain access to market. Read more »

  • Drinking Water Fact Sheet: Radon

    Radon is a naturally occurring radioactive gas formed by uranium and radium in rocks and soil. Groundwater dissolves radon from uranium-containing rock, resulting in generally higher concentrations of radon in well water compared with drinking water derived from surface waters, such as rivers and lakes.

  • Drinking Water Fact Sheet: Nitrate

    The term nitrate refers to a large family of nitrogen-containing organic and inorganic compounds. Each year, 12 million tons of nitrogen are applied as commercial fertilizers, and some 150,000 tons of nitrate compounds are released into the environment by industrial facilities. Read more »

  • Drinking Water Fact Sheet: Lead

    For most Americans, lead exposure has been significantly reduced in recent decades through bans on leaded gasoline and lead-based paint. However, lead remains a serious public health threat for developing fetuses, infants, and children, who are particularly sensitive to its toxic effects. Read more »

  • Drinking Water Fact Sheet: E. coli 0157:H7

  • Drinking Water Fact Sheet: Disinfection Byproducts

    Disinfection byproducts (DBPs) form when chlorine or other disinfectants react with organic material (from the decomposition of leaves and other vegetation) naturally found in drinking water sources. The use of chlorine to disinfect drinking water has been hailed as one of the major public health breakthroughs in the 20th century, resulting in a large decrease in mortality from waterborne infectious disease. However, in 1976 the National Cancer Institute published data showing that chloroform, a chlorination byproduct, caused cancer in rodents. There is now evidence that disinfection—though pivotal in fighting infectious disease—may also result in cancer and other health risks for humans. Read more »

  • Drinking Water Fact Sheet: Cryptosporidium

    Cryptosporidium parvum (C. parvum) is a protozoan parasite known to infect humans and many animal species. The infective oocysts of Cryptosporidium are shed in the feces, and infection can occur by consumption of contaminated food or water, ingestion of contaminated recreational water, or through contact with feces of infected persons or animals. Cryptosporidium is not new, but is has gained recognition, both because it has become more widespread and because of evidence that there are potential life-threatening consequences of infection in the growing population of immunocompromised persons.

  • More Extreme Heat Waves

    Global warming will bring more extreme heat waves. As the United States warms another 4 to 11°F on average over the next century, we will have more extremely hot summer days. Every part of the country will be affected. Urban areas will feel the heat more acutely because asphalt, concrete, and other structures absorb and reradiate heat, causing temperature to be as much as 10°F higher than nearby rural areas.
