Permafrost soils pose unique problems for the remediation of hydrocarbons. Most soils contaminated inx000D
Canada's North are excavated and remediated using landfarm approaches. However, in many northernx000D
communities, the hydrocarbon impacts are located beside, or underneath structures such as homes orx000D
residences, that can not be demolished. Thus, what is needed are methods to stimulate in situ remediation forx000D
hydrocarbons in permafrost soils. A first, and necessary, step is the development of a treatability system tox000D
evaluate what sort of nutrients or other biostimulatory substances should be added to these unique soils. Thex000D
purpose of this Engage is to develop and evaluate a treatability system for CH2M-Hill who can then use thesex000D
results to explore innovative solutions for hydrocarbon contaminated permafrost soils. Using soil collectedx000D
from Old Crow, we will evaluate if one can track aqueous concentrations of hydrocarbons as a surrogate forx000D
soil concentrations, and if so, how long should one track concentrations to evaluate if a remediation system wasx000D
successful or not. Working with CH2M-Hill, we developed a prototype design and this Engage will evaluate ifx000D
this design is successful. Following this, CH2M-Hill will continue to work with Dr. Siciliano to develop andx000D
explore new approaches for in situ remediation in permafrost soils.
