E. coli as sole indicator of water pollution questioned

http://www.sciencedaily.com/releases/2010/...00226093739.htm


ScienceDaily (Feb. 26, 2010) — In Ireland, bacterial contamination of water is a national concern, with the Environmental Protection Agency reporting that over 25% of groundwater samples were contaminated with E. coli in the 2004 to 2006 period. E. coli is the most important indicator used in Ireland and its presence indicates water is unfit for human consumption. It has long been thought that E. coli can only survive for short periods of time in the environment, hence its almost universal use as an indicator of recent faecal contamination of waterways
"Invisible Pink Unicorns are beings of great spiritual power. We know this because they are capable of being invisible and pink at the same time. Like all religions, the Faith of the Invisible Pink Unicorns is based upon both logic and faith. We have faith that they are pink; we logically know that they are invisible because we can't see them."
