Alberta Health Services is warning the public of fecal bacteria in a lake southwest of Edmonton. Elevated levels of fecal bacteria were detected through testing lake water at Zeiner Park Beach at Pigeon Lake, located about 100 kilometres southwest of Edmonton, and AHS is advising people not to swim or wade in the water there. The current levels of bacteria could lead to gastrointestinal illness if someone swallows the water. Contact with the water could lead to skin, ear and eye infections, AHS says.
