Boil water issued for Town of Ingersoll (April 30)

A boil water advisory has been issued by the Southwestern Public Health Medical Officer of Health for all residents connected to the municipal water supply in the Town of Ingersoll.

Until further notice, Public Health advises residents to boil their tap water or use bottled water for drinking, making infant formula or juice, cooking, making ice, washing fruits and vegetables, or brushing their teeth.

To use boiled water, Public Health recommends bringing water to a rolling boil for one minute then allowing it to cool. It may then be stored in clean containers.

This advisory is being issued as a precautionary measure after water sample results from two (2) of six (6) water treatment facilities in Ingersoll had microbiological lab results, indicating that the test was inconclusive for E. Coli and total coliform due to non-target bacterial overgrowth.

Oxford County investigates all instances of adverse water quality and has confirmed:

• Samples from all six (6) municipal wells in the Town of Ingersoll are free of E. coli and total coliform.
• All six (6) water samples from the distribution system were also free of E. coli and total coliform. All four (4) remaining water treatment facility samples results were free of E coli and total coliform.
• The distribution system has been flushed and there is adequate disinfection in the system. 
• The two facilities in question have been placed out of service until two (2) sets of resamples have been taken 24 hours apart showing water is free from bacteria.
