Palmer, in association with Aurora Geosciences, was retained by the Governments of Yukon and the Northwest Territories (NWT) to map and characterize potential aquifers within the portions of the Liard River Basin in Yukon and the NWT. Despite key gaps in surficial and subsurface data throughout the region, the desktop-based study highlighted the occurrence of vulnerable surficial (unconfined) aquifers around several northern communities. Palmer’s preliminary water budget analysis determined that most groundwater recharge occurs in the southern half of the study area where permeable materials are more widespread, slopes are gentler, and permafrost is less extensive. The coincidence of the territorial border with a watershed divide minimizes the amount of direct transboundary groundwater flow.
