An April 3 post on the Huffington Post's Green blog described the Second National Mayor's Challenge for Water Conservation taking place all this month. The post describes the growing popularity of this competition and how the race to conserve water in cities is suddenly an exciting thing.

The article reads, in part:

WASHINGTON (EPA) — In accordance with a consent decree and in line with requirements under the Clean Water Act, the U.S. Environmental Protection Agency (EPA) has proposed a range of options to help reduce dangerous pollutants, including mercury, arsenic, lead, and selenium that are released into America’s waterways by coal ash, air pollution control waste and other waste from steam electric power plants. The proposal includes a variety of options for whether and how these different waste streams should be treated.
