What causes a swim advisory?
Public health units declare swim advisories when the water at recreational beaches is unsafe to swim in. This is usually due to high levels of bacteria in the water, such as E. coli, which can make you sick if ingested. The water at a beach is deemed safe if five testing samples show that there is equal to or less than 200 E. coli per 100 mL of water. Any more than that is deemed unsafe for swimming.
Who tests the water?
Each of Ontario’s public health units is responsible for testing the recreational water within its jurisdiction. Ontario’s Ministry of Environment, Conservation, and Parks is responsible for testing waters within provincial parks. How often the water is tested varies by unit. Some test weekly while others test monthly.
What causes the water to become contaminated?
Stormwater runoff, sewer overflows, sewage treatment plant bypasses, agricultural runoff, faulty septic systems, and large populations of waterfowl all contribute to contaminating water with bacteria. Heavy rainfall and winds will also exacerbate the bacteria.
How do I know whether it’s safe to swim?
Since there are gaps between testing, beachgoers can’t always rely on lab results to tell them whether the water is safe for swimming. There are, however, a few red flags to look for when determining whether the water is contaminated. If the beach is full of waterfowl, such as geese, there’s a good chance the water may contain high levels of bacteria. Uncharacteristically murky water is another sign, as well as dead fish. And if the top of the water looks like it’s had blue or green paint spilled on it, do not go in. That’s a sign of blue-green algae, which can be deadly to pets and harmful to humans.
