The province recently published its “Practices for the Collection and Handling of Drinking Water Samples, Version 2.0, April 1, 2009” (the Guideline), offering guidance for the collection, labelling, storage and transportation of all drinking water samples required under the Drinking Water Systems Regulation (Ontario Regulation 170/03). According to the Ontario government, the Guideline should be used by Ministry of the Environment (MOE) officers who are responsible for the collection, labelling, storage and transportation of water samples. The sampling techniques suggested in the Guideline are also recommended as examples of best practices for owners and operators of drinking water treatment plants. In addition, the Guideline includes container, preservative, labelling, transportation and holding time requirements for drinking water samples being submitted to the MOE’s Laboratory Services Branch for analysis.
