Objectif(s): To contribute to the territorial government’s groundwater monitoring plan by establishing baseline conditions for solutes in the local groundwater around the solid waste facility.
Description du projet: This licence has been issued for the scientific research application No.5245. The objectives of this project are to contribute to the territorial government’s groundwater monitoring plan by establishing baseline conditions for solutes in the local groundwater around the solid waste facility. The research team aim to improve current groundwater vulnerability frameworks to account for anthropogenic sources of contamination under changing environmental conditions. The team investigate the wider temporal and spatial concerns presented by a constant influx of non-degradable contaminants into water resources. These objectives will be accomplished through geochemical data analysis, surface and groundwater sampling and geospatial modelling. Using the existing water geochemistry data from the Yellowknife water licenses, sampling locations were selected to fill gaps in the dataset and investigate anomalous areas. Sampling will be performed within and around the solid waste facility, and will focus on the lakes, springs, wetlands, and groundwater wells. Around 50 samples will be collected. The data collected during field work will be analyzed for sweeteners by Environment and Climate Change Canada (ECCC), general chemistry by Taiga Labs in Yellowknife, and isotopes at McGill University. Results from sampling will be geospatially modelled in Geographic Information System (GIS) for long-term trends and predictive effects of climate change. Communications are already underway with the Yellowknife municipal government and the GNWT hydrogeologist/summer support staff. The original project idea was initiated collaboratively in October 2021, and communications have been continuous since. Field work will be carried out with the summer support staff. Permissions have been sought with the landfill manager for access to the solid waste facility for field work dates. Closer to the date, technical details will be shared and plans for in-person collaboration will be solidified. The fieldwork for this study will be conducted from August 23, 2022 to December 31, 2022
