Seasonal Monitoring of Smith Creek and Scotty Creek, 2019-2021

Our project examined water quality in two catchments in the Dehcho of the Northwest Territories through a partnership between University of Alberta researchers and the Dehcho Aboriginal Aquatic Resources and Oceans Management program. Over three years (2019-2021), we sampled methylmercury, mercury, dissolved organic matter, nutrients, and ions at Smith Creek and Scotty Creek.

Informations sur la collecte de données

Water samples were collected at the edges of the streams. PT1 and PT2 Ultrapens (Myron L Company, USA) were used to measure electrical conductivity, pH, and water temperature. Samples for mercury and methylmercury analysis were collected in certified precleaned amber glass bottles following clean hands-dirty hands protocols. 2x60 mL water samples were filtered in the field, with one sample preserved with hydrochloric acid for dissolved organic carbon and cation analysis, with the other non-acidified for anion analysis and absorbance spectroscopy.
