Abstract

Collected data represents various water samples (surface and subsurface) taken near Yellowknife and Wekweètì, Northwest Territories. Samples were collected irregularly between July 2016 and present from both locations from nearby lakes and drive-point piezometers, filtered in field to 0.45um, and kept cold and in the dark until analyses (generally within three weeks). Water was analyzed for dissolved organic matter (DOM) concentration, DOM composition (via size-exclusion chromatography, UV-visible light absorbance, and elemental ratios), disinfection potential, and concentrations of disinfection by-products (both trihalomethane and haloacetic acids). DOM analysis was completed at the Environmental Geochemistry Laboratory, University of Waterloo, while disinfection demand and DBP concentrations were analysed at the Clean Water Lab, Dalhousie University.

Purpose

The purpose of this project was to establish relationship between dissolved organic matter and disinfection by-product formation from waters near Yellowknife and Wekweeti, Northwest Territories
