EDMONTON – Due to potentially elevated levels of fecal bacteria that are likely present in the water at Big Lake in Edmonton Zone of Alberta Health Services (AHS), AHS continues to advise the public not to engage in any activities that would involve exposure to the water or shoreline of Big Lake. This advisory was initially issued on January 19, 2023 due to sewage run-off that entered the lake and its shoreline after a pipeline carrying wastewater ruptured.
Elevated levels of fecal bacteria may continue to be present at the spill site and surrounding area on the south shore. While it is currently unclear how far the run off may extend along the shoreline, the site of the spill was near Range Road 261 at Lakeshore Estates.
At these suspected levels, gastrointestinal illness may result from ingestion of the water from Big Lake. As well, there is the possibility of skin, ear and eye infections with water contact.
As we enter the spring months and the lake begins to thaw, visitors to Big Lake are advised to take the following precautions:
As always, visitors and residents are reminded to never drink or cook with untreated water directly from any lake or reservoir, at any time. Water-borne organisms, including fecal bacteria, can cause vomiting and diarrhea.
AHS Public Health Inspectors continue to monitor the situation.
Anyone with concerns about their health is encouraged to call Health Link at 811 or speak with a family physician. Anyone with questions or concerns about this incident in particular, or the water in their area in general, can reach out to the Environmental Public Health team: ahs.ca/eph or call 1-833-476-4743.
This advisory will remain in effect until further notice.
