The Ottawa River Keeper is raising an alarm about high concentrations of salt found in early testing of Ottawa area rivers and creeks.
The River Keeper, Elizabeth Logue, said the non-profit organization has begun a winter road salt monitoring program aimed at establishing whether city road salt operations and other de-icing efforts by residents are having a detrimental impact on local waterways.
The early results are already causing concern."There are regulations that are made to determine the levels that are a problem for the environment," Logue said. "We can see concentrations higher than acceptable."
