Technical Support Document for Ontario Drinking Water Standards, Objectives and Guidelines
The primary purpose of the Ontario Drinking Water Standards, Objectives and Guidelines is to provide information for the protection of public health through the provision of safe drinking water.
This document is intended to provide supporting documentation for the Ontario Drinking-Water Quality Standards Regulation O. Reg. 169/03 and serve as a reference for the design and operation of water treatment plants to produce water that continuously satisfies the standards, objectives and guidelines of drinking-water quality. This document also makes reference to the Procedure for Disinfection of Drinking Water in Ontario.
Parameters and their associated standards and objectives are listed alphabetically in Tables 1 through 4. A brief description is provided for these parameters in Appendix A. Some parameters, such as alkalinity, pH and taste, which do not have specific objectives, are listed because for them there is an ideal condition or range for water treatment plant operation or aesthetic water quality.
