If no contamination was found in the drinking water system outside of Reservoir 3, why was a boil water notice issued?
Drinking water regulations require the issuance of a boil water notice if a water quality sampling compliance site demonstrates the presence of E. coli bacteria and the presence of bacterial contamination is confirmed through resampling. The regulations are designed to facilitate proactive water utility and general public actions to minimize the risk of waterborne disease outbreaks. As required by law, the Water Bureau consulted directly with the Oregon State Human Services Drinking Water Program to obtain required authorization and approval of the boil water notice before distribution.
