The United Nations (UN) theme for World Environment Day 2003 was "Water: Two Billion People are Dying for It!" It was not en exaggeration. The UN reports that one person in six lives without regular access to safe drinking water. Over twice that number—2.4 billion people—lack access to adequate sanitation. Water-related diseases kill a child every eight seconds, and are responsible for 80 percent of all illnesses and deaths in the developing world. Cholera outbreaks, due to water contaminated with raw sewage, occur regularly in India and Bangladesh and less frequently in many other countries. In Africa in 1997, 5,853 deaths due to cholera were reported to the World Health Organization. It is a situation, the UN said, "made all the more tragic by our long-standing knowledge that these diseases are easily preventable." see also: Acid Rain; Agriculture; Clean WAter Act; Cryptosporidiosis; DDT (Dichlorodiphenyl trichloroethane); Health, Human; Nonpoint Source Pollution; PCBs (Polychlorinated Biphenyls); Point Source; Snow, John; WAstewater Treatment; WAter Treatment.

The Great Lakes Basin includes areas of the eight Great Lakes states: New York, Pennsylvania, Ohio, Minnesota, Indiana, Illinois, Wisconsin, and Michigan. In 1995, the U.S. Environmental Protection Agency (EPA) and the Great Lakes states agreed to a plan called the Great Lakes Initiative, aimed at reducing pollution and restoring the health of the Great Lakes. The plan included setting water quality standards for twenty-nine pollutants. In 2000, the EPA initiated a ten-year phase-out of the use of mixing zones for bioaccumulative chemicals in the Great Lakes. The EPA says this ruling will reduce discharges of toxic chemicals by 700,000 pounds a year.
recharge the process by which water is added to a zone of saturation, usually by percolation from the soil surface; e.g., the recharge of an aquifer mixing zone an area of a lake or river where pollutants from a point source discharge are mixed, usually by natural means, with cleaner water bioaccumulative relating to substances that increase in concentration in living organisms as they take in contaminated air, water, or food because the substances are very slowly metabolized or excreted
