Archives of Beach Water Quality for 2011

Please note Ottawa Public Health collects beach water samples every day. The results take 24 hours to process in the laboratory, so the swim and no-swim advisories are based on sample results taken from the previous day.

Test results indicate amount of E.coli per 100 mL of water
