History of DOM & DBP in Drinking Water Sources across the Northwest Territories
Borealis
Aukes, Pieter; Venkiteswaran, Jason; Schiff, Sherry; English, Michael; Department of Municipal and Community Affairs — 2020-11-27 This dataset is a compilation of public water quality records from the Department of Municipal and Community Affairs (MACA), Government of Northwest Territories for all communities in the Northwest Territories, 1994-2016. Water quality data includes measures of true colour and concentrations of dissolved organic carbon (DOM) and disinfection by-products (DBP), specifically trihalomethane species. Each record includes community and region information, sampling dates, water sampling source, lab information, and DOM and DBP values. <p><p>Data is derived from MACA records available online at https://www.nwtdrinkingwater.ca/operations/water/water_raw.asp

Data used in 'Size-Based Characterization of Freshwater Dissolved Organic Matter finds Similarities within a Water Body Type across Different Canadian Ecozones'
Borealis
Aukes, Pieter; Schiff, Sherry; Venkiteswaran, Jason; Elgood, Richard; Spoelstra, John — 2020-07-17 Field collection of freshwater surface and groundwater samples from five ecozones across Canada. Concentration and composition (via UV-absorbance and size-exclusion chromatography) of dissolved organic matter were analyzed across all sites and compared across hydrologic compartments to identify similarities in dissolved organic matter (DOM).

Data used in 'Composition Wheels: Visualizing dissolved organic matter using common composition metrics across a variety of Canadian Ecozones'
Borealis
Aukes, Pieter; Schiff, Sherry — 2020-12-11 Field collection of surface and groundwaters across Canada for characterization of dissolved organic matter (DOM). DOM was characterized using UV-visible absorbance, size-exclusion chromatography, and elemental ratios (dissolved organic carbon to dissolved organic nitrogen). Measures were compared in all samples to determine which select measures give us the best representation of DOM composition. These were then used to develop a simple visualization tool (Composition Wheel).

1.Turn on the map filter by clicking the “Limit by map area” toggle.
2.Move the map to display your area of interest. Holding the shift key and clicking to draw a box allows for zooming in on a specific area. Search results change as the map moves.
3.Access a record by clicking on an item in the search results or by clicking on a location pin and the linked record title.
Note: Clusters are intended to provide a visual preview of data location. Because there is a maximum of 50 records displayed on the map, they may not be a completely accurate reflection of the total number of search results.
