Description: The purpose of this document is to provide guidance for the collection, labelling, storage, transportation, and chain of custody of all drinking water samples that fall under the Drinking Water Systems Regulation (Ontario Regulation 170/03). These practices provide the minimum level of quality assurance necessary to ensure that the samples analyzed continue to accurately reflect the quality of the raw, treated, and distributed water supply. They are intended to supplement the analytical method quality assurance & control activities already in place. Introductory sections explain the rationale for sample collection & handling protocols and the nature of representative sampling & data. Information is then presented on aspects of sampling (including sampling design & location, containers, techniques & equipment, preservation, holding times, & storage) and chain-of-custody measures used to ensure the integrity of the sample & the resulting data.
