Assessment of soil capping for phosphogypsum stack reclamation at Fort Saskatchewan, Alberta
DownloadFall 2009
Phosphogypsum (PG), an acidic byproduct of phosphoric acid production during phosphate fertilizer manufacturing, is commonly stacked on the facilities and capped with soil at decommissioning. The research evaluated soil capping depth (0, 8, 15, 30, 46, 91 cm) effects on response of five seeded...

Phosphogypsum (PG) is an acidic by-product created during phosphate fertilizer production (Rutherford et al 1994). In open or operational PG stacks, airborne fluorides are emitted from phosphogypsum process water pond surface evaporation or particulate fluoride that can be transported as fluoride...

Effects of Alternative Forest Harvesting Strategies on Snowpack Dynamics and Seasonal Soil Moisture Storage in Alberta's Mountain Headwaters
DownloadFall 2019
Snowpack accumulation and melt dynamics, and soil moisture storage (SMS) play a critical role in regulating stressed regional water supplies in the southern Alberta Rockies. However, these processes are sensitive to impacts from forest cover losses by timber harvesting and associated land...

Influence of Soil Cap Depth and Vegetation on Reclamation of Phosphogypsum Stacks in Fort Saskatchewan, Alberta
DownloadSpring 2013
This study quantified environmental parameters to develop reclamation strategies for phosphogypsum stacks. Research was conducted on phosphogypsum stack experimental plots established in 2006 (6 soil cap depths, 5 vegetation treatments), and soil capped slopes seeded in 1998. Significant root...

Arsenic is a highly toxic and ubiquitous element. To this day, millions of people are exposed to arsenic contamination, which poses global health concerns. Phytoextraction performed with willows, a form of phytoremediation, is a promising means of cleaning up soils containing hazardous levels of...
