Description

Alberta Environment has identified water quality in the North Saskatchewan River (NSR) as a major issue to be addressed in the North Saskatchewan Regional Plan (NSRP). Knowledge of the source, transport and fate of sediment-associated contaminants in this watershed is fundamental to understanding and managing anthropogenic impacts on water quality and source assessment study conducted for Alberta Environment and Water to provide information regarding the following two research questions: 1) What are the physical, geochemical and contaminant characteristics of sediment in the NSR and is tributaries, and 2) What are the key spatial sources in sediment in the NSR?

Description

The work presented herein comprises a phase 1 study to provide an assessment of the current state of knowledge regarding the nature of sediment inputs, transport and contaminant relationships in rivers with the intention of using this review to outline a scope and methodology to address key knowledge gaps. Such information is necessary to develop strategic and cost-effective monitoring programs for management of the North Saskatchewan watershed. Specific objectives of this study are to review and compile current knowledge regarding: 1) the nature, source, transport and fate of cohesive sediment and associated contaminants in rivers; 2) the effect of land-use change on the source and fate of sediment-associated contaminants; 3) as assessment of frameworks and methodologies used to evaluate the provenance and fate of sediments in river environments and; 4) make recommendations for future work to evaluate the provenance, transport, fate and effect of cohesive sediment on the NSR.
