In summary, the risk assessments identified COCs in soil that may have potential to cause adverse effects, especially to soil invertebrates and plants, although this is principally a theoretical risk owing to important habitat limitations in the most...

This report attempts to provide a preliminary review of the some of the possible impacts, monitoring, and mitigation measures for many of the pollution issues including sewage and waste disposal, mining and smelter activities, various large industrial...

This study focused on the diffuse sources of nutrients and the trophic status of the Upper Bulkley River. Monthly water chemistry monitoring of the Upper Bulkley and tributaries was conducted between November 1997 and March 2000, and the end of growing...

This Assessment Report considers the proposed Morrison Copper/Gold Mine Project’s potential to cause significant adverse environmental, economic, social, heritage, and health effects. It identifies measures to prevent or reduce adverse effects, and sets out...

This operational plan is the initial product of a partnership between the Office of the Wet’suwet’en and the Province of British Columbia to develop a water monitoring and assessment system for the recently established Morice Water Management Area (MWMA).
