English: The level of e.coli contamination in clean water supplies increases 5 times

Over the past two years, the risk of contaminating public drinking water (in England and Wales) by reducing human and animal waste is more than half. However, the current water sample results revealed that: the level of contamination by the presence of E.coli bacteria in clean water supplies has increased 5 times higher than the previous two years. here.

"Only about 53 points of drinking water (boiled) served about 93,000 people during 2009. By the end of 2010: over 264 public water supply points still have the potential to pose a danger to human health, need to be upgraded and retooled , " according to a report by the Environmental Protection Agency (EPA).

A total of 250,000 water samples were tested in 2009: an average of 27 water samples (from 944 samples taken from public clean water supplies) had 1 piece of water contaminated with E. coli, reducing significantly, compared to the proportion of 39 samples of water, one sample was contaminated with E. coli in 2008; In other areas, about one-sixth of the water sample of the private water supply group, usually operated by homeowners groups, has been infected with E.coli at least once.

"The standard for clean drinking water must be without E. coli bacteria" according to Gerard O'Leary, EPA's Environmental Enforcement Office . " However, E. coli bacteria may come from a number of sources: septic tanks, animal waste water treatment systems; cattle drinking water from rivers, streams or inadequate disinfection.

However, the Environmental Protection Agency (EPA) has 28 guiding documents (legally binding) in 2009, but so far the phenomenon of public clean water supplies is contaminated by micro E.coli bacteria has not yet improved.
