"Cracked Sewers Bleed Fecal Germs"
"New studies in California and Wisconsin reveal a dirty little secret: Out of sight, many urban sewer pipes are failing and germ-ridden filth is bleeding out.
The studies tracked material hemorrhaging into storm drains. These pipes, which channel their contents into streams and coastal waters, are designed to collect fairly clean rainwater and runoff from watered lawns. Yet raw sewage at times constituted nearly 20 percent of one local storm drain’s flow, reports Patricia Ann Holden of the University of California, Santa Barbara and her colleagues."Source: Science News, 08/01/2011
