Marina Four

Toronto, Ontario

Marina Four is a well-protected slip that sits between Rees St. and Lower Simcoe St., right in the heart of the Harbourfront Centre. It is adjacent to the Concert Stage, and under the Amsterdam pedestrian bridge. While not a popular swimming location, it is extensively used by boaters many of whom call the marina home. The City of Toronto does not monitor here.

A combined sewer outfall is located in the northeast corner of the marina. Swim Drink Fish staff along with trained citizens scientists monitor this location twice a week, on Tuesday and Thursday morning. These citizen scientists are a part of the Toronto Monitoring Hub, which is one of Swim Drink Fish’s monitoring hubs.

MONITORING FREQUENCY

Marina Four is sampled from May 22nd to November 1st

SOURCE INFORMATION

Swim Drink Fish staff, interns, and volunteers monitor recreational water quality in the Toronto Harbour during the summer months. The guidelines followed are the 2014 Ontario’s Provincial Water Quality Objectives, set by the Ministry of Environment at 100 E.coli per 100 millilitres of water.

Water is sampled for E. coli and Total Coliform at all sites. The water is sampled twice a week, on Tuesdays and Thursdays from May 22 to September 30th. Sampling in October and November will occur once a week. Results are available 24 hours after samples are collected.

Beaches are posted when the geometric mean of 5 samples collected within a given swimming area and within a 30-day period exceeds 100 E. coli / 100 ml of water. A The Ministry of the Environment F-5-5 procedure says that a clean beach must meet water quality criteria for at least 95% of the swimming season, even if it is near a sewage pipe or combined sewer outfall.

Test results are expressed as Most Probable Number (MPN) of E.coli per 100 ml by using the IDEXX Quanti-Tray/2000 MPN Table.

A beach is marked Green when geometric mean of 5 samples results are equal or below 100 E.coli / 100 ML water.

A beach is marked Red when the geometric mean concentration (minimum of five samples) is above 100 E.coli / 100 ML water, according to Ontario’s water quality guidelines.

A beach is marked Grey when there are no current results or there is no available information.

Results are posted as soon as lab results are available. Results will be communicated through the swim guide website and apps.
