Black Rock Beach

Source Information

Halifax Regional Municipality staff monitor Halifax beaches and collects samples at designated beaches weekly from July 1st to August 31st. All designated beaches are tested for E. coli and some saltwater beaches are tested for Enterococci. When bacteria counts exceed the provincial standard, the beach is considered to be unsafe for swimming and warning signs are posted at the beach. When bacteria counts exceed the provincial standard, the municipality also publishes Public Service Announcements on its website and announces the beach closure through social media channels. Swim Guide checks the Halifax Regional Municipality website daily for updates during the swimming season. A beach is marked Green when when the geometric mean of 5 samples collected within a 30-day period is below 200 E. coli / 100 ml of water. A beach is marked Red when the geometric mean of 5 samples collected within a 30-day period exceeds 200 E. coli / 100 ml of water or when a single sample exceeds 400 E. coli / 100 ml of water. Officials will also close a beach if the Enterococci level reaches 70 counts per 100 ml of water. Beaches may be retested when counts exceed 200 E.Coli per 100 ml of water. When counts exceed 35 Enterococci per 100 ml beaches are retested every 24-48 hours until levels drop below the accepted levels and closure is considered. A beach is marked Grey when reliable or up-to-date information is not available.
