Practices for Collection and Handling of Drinking Water Samples
This guide provides information to anyone who collects and submits a sample to a licensed drinking water testing laboratory in Ontario, as well as to all licensed laboratories. This sampling guide was made so that the requirements of O. Reg. 248/03 section 9.(1)(a) can be met.
This document provides guidance for:
- water treatment plant owners/operators or anyone who may collect and submit a sample to a licensed drinking water testing laboratory in Ontario to meet Ontario’s environmental regulatory and approval requirements
- provincial officers sampling to verify the integrity of a drinking water system’s self-monitoring information, or in response to adverse water quality notifications

Lead
‘Children up to six years old are more sensitive to the effects of lead because they are still developing and their small bodies can absorb it more easily than adults. Even small amounts of lead can be harmful to young children, infants and pregnant women (Ministry of the Environment, Conservation and Parks, 2020).’
The following links provide information regarding lead in drinking water and how to minimize exposure through line replacement, flushing, treatment and sampling programs.
