The World Meteorological Organization (WMO) Solid Precipitation Inter-Comparison Experiment (SPICE) officially began in the (Northern Hemisphere) Fall of 2012 with the objective of characterizing and providing guidance on the performance of automated systems for the in situ measurement of solid...

Drought projections on seasonal to annual time scales are presented for Canada over the twenty-first century, based on the Standardized Precipitation Evapotranspiration Index (SPEI). Results make use of bias-corrected temperature and precipitation projections from 29 global climate models...

The Environmental Damages Fund (EDF), created by the Government of Canada in 1995, follows the Polluter Pays Principle to ensure that those who cause damage to the environment take responsibility for their actions. Prosecutors and judges can recommend that financial penalties (fines, awards...

This study examined the effect of two dinonylnaphthalene sulfonic acids (NSAs) on freshwater organisms: calcium dinonylnaphthalene sulfonate (CaDNS), and dinonylnaphthalene disulfonic acid (DNDS). Chronic effects were characterized by exposing fertilized fathead minnow eggs to sediment-associated...

The datasets and maps are associated with a research study. Annual total (dry + wet) deposition fluxes of nitrogen (nitric acid, nitrate and ammonium) and sulfur (sulfur dioxide and sulfate) were determined at 15 Canadian Air and Precipitation Monitoring Network (CAPMoN) sites from 2000 to 2018....

In 2012 samples of raw influent and final effluent wastewater from five municipal wastewater treatment plants at various locations in Canada (sites to remain anonymous, designated in this data file as MH, OX, Q, TB, U). Also, leachate was collected from three landfill sites (sites to remain...

In 2011-2014 samples of groundwater and septic wastewater were sampled from various sites in Ontario, Canada. Most of the groundwater sites were impacted by septic wastewater plumes. The samples were analyzed for four artificial sweeteners (acesulfame, saccharin, cyclamate, sucralose),...

In 2018 samples of raw influent and final effluent wastewater from twelve municipal wastewater treatment plants at various locations in Canada (sites to remain anonymous, designated in this data file as NW, J, C, SM, JL, TB, GA, PA, PN, E, V, H). The samples were analyzed for four artificial...

In 2016-2019 water samples were collected at Lake of the Woods as part of a research program to determine sources and fate of nutrients in nearshore areas. These included samples of lake water, groundwater, streams, and septic wastewater. The samples were analyzed for nutrients (total and...

The objectives of the present long‐term study, spanning a 45 year period, were to 1) investigate the temporal trends of total mercury (THg; muscle and liver) and selenium (Se; liver) in ringed seals (Pusa hispida) from different regions of the Canadian Arctic; and 2) examine possible...

In 2018 samples of raw influent and final effluent wastewater from fourteen municipal wastewater treatment plants at various locations in Canada were analyzed for priority alkyl aryl sulfonates (AAS) using the methods developed by Van Stempvoort and Brown (2018). The analyses included seven...

Continuous, year-round measurement of stream stage that is later converted to flow using a stage-discharge relationship occurs on at/near the lake outflows and 2 other stations along the principal watershed tributary, Norberg Creek. Measurements ended in 2016. Supplemental Information The Climate...

A database of verified tornado occurrences across Canada has been created covering the 30-year period from 1980 to 2009. The data are stored in a Microsoft Excel spreadsheet, including fields for date, time, location, Fujita Rating (intensity), path information, fatalities, injuries, and damage...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Pulp and paper effluent quality indicator reports the percentage of acute lethality, biochemical oxygen demand and total...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Land-use change indicator reports the proportion of agricultural land that has been converted to settlement and the...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Boil water advisories indicators provide an overview of of the main reasons why boil water advisories are issued in...

In the Lake Winnipeg Basin (LWB), at both basin and regional scales, there are currently gaps regarding the significance of groundwater as a mediator of nutrient and contaminant fluxes to Lake Winnipeg. During 2018, surface water and groundwater samples were collected from various locations...

Water chemistry is measured at several stream stations in the Turkey Lakes Watershed (TLW) to quantify mass fluxes, cycling and budgets. Environment and Climate Change Canada (ECCC) tends to focus on lake outflow stations and other stations situated on Norberg Creek (the major drainage channel in...

The snowpack has been sampled during both the accumulation and ablation stages at as many as 13 sites within the Turkey Lakes Watershed, Algoma, central Ontario, Canada since 1980, although more quantitative surveys began in 1989. Snow depth and a physical description of snowpack have been...

Groundwater wells were installed in the Turkey Lakes Watershed basin in the early 1980’s. These test wells were installed in eight sub-basins of the watershed and range in depth from 0.5 to 9.7 metres. They are located on a variety of terrain throughout. The water chemistry has been sampled at...
