Monitoring 

The City undertakes weekly Escherichia coli (E. coli) testing for surface and groundwater drinking water systems and in the effluent at the Wastewater Treatment Facility. This monitoring is undertaken to protect human health and ensure regulatory compliance. The City also undertakes a monthly surface water quality monitoring program of creeks as part of our source water protection program and to ensure compliance with provincial Environmental Compliance Approvals

As outlined in a September 10 2025 memo to City Council re Water Quality Sampling Dyments Creek, staff are advancing a more robust sampling program that will include E. coli in all monitored City creeks – with consideration for multiple sampling locations and different weather conditions.
