Raw sewage is no longer flowing from the Calgary bedroom community of Redwood Meadows into a forest near the Elbow River, officials say.
For nearly two weeks, untreated sewage has been spewing onto the land, which is part of the Tsuu T’ina native reserve, because of a blocked line.
The raw human waste was being dumped roughly 500 metres from the Elbow River, which feeds Calgary’s Glenmore Reservoir.
On Monday Tsuu T'ina band administrator Kevin Littlelight said the sewage system for Redwood Meadows — which is also on First Nations land — was fixed on Friday and that sewage flowing properly into a lagoon on the reserve.
Redwood Meadows town manager Pat Evans also said the problem had been corrected.
"Everything's been kind of put back to normal," Evans said.
Tsuu T’ina officials said the site where the sewage was dumped had been cleaned up.
CBC News has not been able to independently confirm any cleanup.
City of Calgary water officials have stepped up water sampling as a result of the sewage spill.
"We are concerned as always with what is going on in our watershed... We are increasing some of our sampling. But we are confident that our water treatment plant will continue to deliver high quality drinking water," said Nancy Stacker, manager of water quality service for the city.
Littlelight says "suspicious" concrete caused the blockage, adding law enforcement officials are investigating.
CBC News hired an independent water lab to run tests for pathogens at the dump site and on the river. Experts concluded there are concerns about dangerous pathogens and fecal coliform entering the waterway, which is a source of Calgary's drinking water.
Meanwhile, Environment Canada issued a statement to CBC News Monday, stating officers completed an on-site inspection and "have not found any evidence of a Fisheries Act violation in fish bearing waters. No further action from Environment Canada is required."
