Description

Presents findings of a study to complete a problem formulation for human health risks associated with surface water impacts after a wildfire. The main goal of the work was to better understand and assess potential human health risks from the Horse River Wildfire on surface water bodies that serve as drinking and recreational water sources and apply learnings to future wildfires. Five recommendations are provided, including a review of facilities in Alberta that are most susceptible to wildfire associated surface water risk and generation of a small suite of key indicator compounds to help notify water users of the wildfire related impacts to water.

Description

This technical report, compiled by Hatfield Consulting, describes the experimental design used to determine the toxicity of oil sands process-affected water (OSPWW) treated using Syncrude's coke-slurry treatment process. The three primary components of the study design are: chemical characterization of untreated and treated OSPW; toxicological testing of treated OSPW; and assessment of aquatic invertebrate community mesocosm responses to treated OSPW.

Description

This study provides an overview of streamflows and water allocations in the Upper Athabasca Region of Alberta, which encompasses the upper catchment of the Athabasca River. The overall objective was to gain a better understanding of the current state of surface water resources in the region by completing an analysis of historical streamflow and surface water allocations over the most recent, minimum 30-year period for which a complete and reliable dataset is available (1983 to 2013 for streamflows, and 1983 to 2017 for allocation data). It is important to note that the scope of this study was limited to surface water and does not include any analysis or consideration of groundwater supply and allocations.
