This dataset contains results for the City of Calgary's Watershed Monitoring Program. The program monitors surface water quality across a network of sites that include rivers, tributaries, and reservoirs within the Calgary region. Sampling locations have been added, removed, or modified over time. Grab sampling methodologies are used for sample collection. The City of Calgary uses approved and documented analytical testing methodologies, and the City of Calgary laboratory is accredited to the ISO/IEC 17025 standard. Quality Assurance programs track and ensure consistent laboratory performance. Changes in data over time, such as method detection limits, accredited testing parameters, and formatting are the result of newer analytical techniques and improved data quality standards.
