Humber Bay Park West

Etobicoke, Ontario

Part of a network of small peninsulas stretching out into Lake Ontario, Humber Bay Park West is a beautiful spot on the city's waterfront. The rocky beach is not monitored for recreational water quality by the city of Toronto. Humber Bay is a very popular scuba diving site, especially with beginners. Trails behind the beach make for a good walking and bicycle route. This side of Humber Park is home to a few boating clubs and docks, which means it has slightly less green space than its Eastern counterpart.

Although a variety of recreational activities takes place in the water here, water quality at Humber Bay Park is currently unmonitored by the City of Toronto. Water quality concerns at this site are tied to its close proximity to the Humber Wastewater Treatment Plant. A small group of trained citizen scientists is undertaking weekly sampling for E. Coli until the end of August 2018. Information and results of sampling will be posted here until the last week of August 2018. After this period, recreational water users are advised to be cautious as E. coli bacteria can cause health problems in humans and pets.

SOURCE INFORMATION

Trained community members monitor recreational water quality at one location in the Humber Bay Park West during the summer months. The standards followed are Ontario’s Provincial Water Quality Objectives, set by the Ministry of Environment and Climate Change at 100 E.coli per 100 millilitres of water.

Water is sampled for E. coli and Total coliform at all sites. Sampling occurs once a week on Tuesday morning from the June 25th to September 30th, 2018. Results are available 24 hours after samples are collected, on Wednesday afternoons.

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 Ministry of the Environment procedure says that a clean beach meets water quality criteria 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 cfu (colony forming units) 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 equal to or 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.
