Boil Water Advisories

A Boil Water Advisory is issued by Ontario Parks to protect consumers from potential health risks related to drinking water of an unacceptable microbiological quality. Park visitors may choose to boil water for at least one minute or consume commercially packaged water for drinking during an advisory. Campers coming to Algonquin Park should plan accordingly, or access potable water at other campgrounds in Algonquin Park, until further notice.

Boil Water Advisories are in effect at the following locations in Algonquin Park.

• None at this time.

Beach Closures

Beach closures are typically enacted by Ontario Parks when bacterial samples for Escherichia coli (E. coli) are over the acceptable limits (200 bacteria per 100mL of water). High levels of E. coli signal fecal contamination (possibly from humans and animals), which indicates the likely presence of other harmful viruses and parasites. Swallowing contaminated water can cause gastrointestinal illness (diarrhea, cramping), while contact can trigger painful eye, ear, and skin infections, especially for children, the elderly, and those with weakened immune systems. Ontario Parks posts beaches with signage when closed. A beach will remain closed until water tests confirm the beach is safe for swimming.
