Which Ontario regulation describes operational checks and sampling requirements for municipal drinking water systems?

O. Reg. 123/98
O. Reg. 170/03
O. Reg. 764/90
O. Reg. 150/06

The correct answer is: O. Reg. 170/03

The regulation that outlines operational checks and sampling requirements for municipal drinking water systems in Ontario is O. Reg. 170/03. This regulation is essential as it sets the standard for water quality monitoring, treatment processes, and reporting obligations for municipal systems. It emphasizes the need for continuous monitoring and specific sampling protocols to ensure that the drinking water supplied to the public meets established safety and quality standards. This is critical as it helps protect public health by ensuring that municipal water systems operate within the regulatory framework designed to maintain safe drinking water. The other regulations mentioned have different focuses; for instance, O. Reg. 123/98 pertains to procedures for source water protection, O. Reg. 764/90 addresses pollution prevention and control in industrial activities, and O. Reg. 150/06 involves the accreditation of laboratories that analyze drinking water samples. Thus, they do not pertain specifically to the operational checks and sampling requirements for municipal systems as O. Reg. 170/03 does.
