The latest Mt Polley water samples are consistent with previous samples according to the Ministry of Environment.
Although the samples showed turbidity levels above the BC drinking water guidelines, and total aluminum above Health Canada drinking water guidelines, the Ministry says there is no evidence of any adverse health effects.
Interior Health who has reaffirmed that surface water located outside of the impact zone meets safety guidelines, advises residents who are using the surface to treat the water for naturally occurring pathogens.
Results for aquatic life meanwhile also continued to show total copper levels and dissolved aluminum above the chronic and acute water quality guidelines.
The Ministry says further long-term monitoring and testing is necessary to determine and understand any potential long-term impacts.
The full results and explanations are available on the Ministry of Environment’s dedicated Mt Polley website.
