Bacteria levels double in water supplied from private wells
The quality of drinking water from private wells has been identified as a major cause of concern, according to the latest drinking water report from the Environmental Protection Agency (EPA).
Instances of VTEC, a harmful strain of E. coli, which may lead to kidney failure, have doubled in 2011. Contaminated well water is believed to be a major source, the report stated.
"We are concerned about the growing number of VTEC cases," said Valerie Doyle, senior inspector with the Office of Environmental Enforcement.
"Any form of E. coli is an indicator of fecal matter in the water supply, and VTEC is a harmful form of E. coli. It may cause gastroenteritis, but its toxins can lead to far more serious consequences including kidney failure," Ms Doyle explained.
"We would urge the owners of private supplies to check their water sources. They also get vital information on what to look out for on Local Authority and EPA websites."
The poor weather this summer is believed to have caused serious difficulties for people with wells supplying domestic drinking water.
High levels of rainfall can lead to contaminants being washed into wells as private supplies are less secure than public water supplies.
"We would urge the owners of private wells to test them carefully, given the bad weather we've had," said Ms Doyle.
