Environmental Health-Safe WaterGoals
� Prevent or reduce the burden of water-borne illness related to drinking water
� Prevent or reduce the burden of water-borne illness & Injury related to recreational water use
Ministry of Health-Ontario Public Health Standards

Recreational Water and Beach Management Protocol
Purpose• Prevent or reduce the burden of water-borne
illness & Injury related to recreational water use at public beaches
Weekly Beach Inspections� Weekly tests for E. coli� Monitor for BGA

WarningWater was unsafe
yesterdayNot sure about todayCome back tomorrow
TomorrowWater was unsafe again yesterday
We are still not sure about today, but
We can tell you that tomorrow
WarningBacterial Levels exceed the provincial standard Unsafe for swimming

3 4 The Next DayIf you swam yesterday, you're okay, water was
fine! Don’t worry!Today "might" be fine too
BUT-We won't sample again until next Wed.
Have a great day!

Neurotoxins(e.g., Anatoxins)
Hepatotoxins(e.g.,
Microcystins)
Dermatoxins(e.g.,
Apylsiatoxins)
Most common
Cell rupture
Cyanobacteria(BGA)
Cyanotoxins
Potential Health EffectsCyanotoxin Symptoms
Hepatotoxins Vomiting, diarrhea, fever, abdominal cramps, and potential liver damage
Dermatoxins Itchy, irritated skin and eyes
Neurotoxins Paralysis, seizure, and potentially death
Severity of symptoms is dependent on the route of exposure, dose, and type of toxin
