Lead Contamination In Washington, D.C. Drinking Water
While performing research into premature pipe corrosion for the District of Columbia Water and Sewer Authority (WASA) in 2001, Marc Edwards, an expert in plumbing corrosion, discovered lead levels in the drinking water of Washington, D.C., at least 83 times higher than the accepted safe limit. He found that the decision to change from chlorine to chloramine as a treatment chemical had caused the spike in lead levels. The contamination has left thousands of children with lifelong health risks and led to a re-evaluation of the use of monochloramine in public drinking-water systems After the ''Washington Post'' ran a series of front-page articles about Edwards's findings, resulting in widespread public concern, the United States House of Representatives conducted an investigation. The House found that the U.S. Centers for Disease Control and Prevention (CDC) had made "scientifically indefensible" claims in a report that had indicated there was no risk from the high lead levels.

American University
The American University (AU or American) is a private federally chartered research university in Washington, D.C. Its main campus spans 90 acres (36 ha) on Ward Circle, mostly in the Spring Valley neighborhood of Northwest D.C. AU was chartered by an Act of Congress in 1893 at the urging of Methodist bishop John Fletcher Hurst, who sought to create an institution that would promote public service, internationalism, and pragmatic idealism. AU broke ground in 1902, opened as a graduate education institution in 1914, and admitted its first undergraduates in 1925. Although affiliated with the United Methodist Church, religious affiliation is not a criterion for admission.

Lead
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
