Assessing Spatial and Temporal Variation in Source Water Quality and Drinking Water Treatability Across a Gradient of Forest Harvest on Vancouver Island, BC
DownloadFall 2021
On Canada’s Pacific Coast, forestry is integral to society. Although economically important, harvesting practices may alter source waters that originate in forested watersheds through changes in suspended solids (SS) and dissolved organic matter (DOM). Each of these metrics has the potential to...

Diversity of wetland non-biting midges (Diptera: Chironomidae) and their responses to environmental factors in Alberta
DownloadSpring 2016
Wetlands provide a wide range of services, including improving water quality, providing habitats for wildlife, and storing floodwaters. In Alberta, wetlands cover about 21% of the landscape of the province. In Alberta, as elsewhere, wetlands have suffered from human activities and many have...

I investigated, water, invertebrates and fishes from lakes in Banff National Park and Kananaskis Country, Alberta for selenium (Se), an element known to be toxic to vertebrates. At some depths, Se concentrations in sediment exceeded recognized thresholds for bird and fish reproductive...

Spatial variations of total and dissolved trace elements and their distributions amongst major colloidal forms along and across the Lower Athabasca River
DownloadFall 2020
The Athabasca River (AR) is the longest river in Alberta with a wide variety of natural and potential anthropogenic inputs. The purpose of this study was to quantify the spatial variation of trace element (TE) concentrations and forms in this aquatic system. Water samples were gathered along a...

The Effect of Source Water Quality on Water Treatment Costs: Evaluation of Source Water Protection Practices
DownloadSpring 2020
A few high-profile forest fires and floods in recent history has exposed the vulnerability of Canadians’ drinking water supply systems to extreme events and their long-lasting consequences. Elevated levels of contaminants in surface waters can force downstream communities to engage in costly...
