Municipal water supply meets, and often exceeds, water quality standards
The Regional Municipality of Durham has received phone calls recently from concerned residents about statements made by sales representatives of a private company selling water treatment devices. The sales representatives, currently going door-to-door, imply they are working for the Region of Durham and some have even claimed to be meter readers. They ask to conduct an in-house water test and, according to residents, they use aggressive sales tactics, while making claims that the water testing is mandatory.
Residents are reminded that the Region of Durham does not sell or endorse water treatment equipment for residents using the municipal water supply systems. However, we are committed to providing clean, safe drinking water to residents. Information on water quality testing is available from the Region by contacting the Works Department at 905-668-7711, or view our Water Quality Reports online.
The Regional Municipality of Durham provides safe drinking water to residents using the municipal water supply system on a continuous basis—meeting and in many cases bettering, all of the Ontario Drinking Water Quality Standards.
Water drawn from the municipal water supply is monitored for quality at the Region’s six surface plants and eight groundwater systems. In addition, all water in the municipal water system undergoes treatment to meet the Ontario Drinking Water Quality Standards, prior to entering the water distribution system. In-plant samples are collected and tested on site each day by a licensed operator, while online analyzers monitor the process on a continuous basis.
The quality and safety of the Region’s water is confirmed at an ISO 17025 accredited laboratory, which is licensed by the Ontario Ministry of the Environment—a requirement of the Ontario Drinking Water Regulations set by the province of Ontario.
Residents are encouraged to call Durham Regional Police at 1-888-579-1520 to report these incidents.
