O. REG. 129/04
O. REG. 170/03
O. REG. 169/03
O. REG. 200/03

The correct answer is: O. REG. 169/03

The correct answer pertains to O. REG. 169/03, which establishes the minimum acceptable drinking water quality standards in Ontario. This regulation is part of the legislative framework aimed at ensuring that drinking water is safe and meets specific criteria to protect public health. O. REG. 169/03 details the various microbial, chemical, and radiological parameters that drinking water must be tested against, providing a comprehensive guideline for drinking water quality. Understanding this regulation is critical because it not only lays out the quality standards but also aligns with monitoring and reporting requirements that operators must adhere to in water treatment and distribution processes. This ensures that any drinking water provided to the public meets rigorous safety conditions to prevent health risks associated with contaminated water supplies.
