  • The focus of this research was to identify environmental risk factors that play a critical role in the contamination of drinking water wells with Escherichia coli. This study used data from a case control-study carried out between April 2005 and September 2006 in Ontario and Alberta, using private water samples submitted from participating public health laboratories. Significant risk factors associated with Escherichia coli contamination of private drinking water wells included the type of water well used, the age of the water well, the housing of livestock on the property and total household income. The age of the water well was identified as a mediator for the type of water well used. The associations between environmental risk factors and Escherichia coli contamination of private drinking water wells provide rational for public health programs to highlight factors home owners should consider when working to prevent well water contamination and identify potential sources of contamination.
