This dataset contains the total annual releases of radionuclides released directly to the environment through direct discharge from uranium and nuclear substance processing facilities in Canada.This original radionuclide releases dataset of the uranium and nuclear substance processing facilities provides results for both stack emissions and direct discharge (i.e. releases to water). The dataset has been divided in two subsets for better discoverability. In this record as its title indicates, you will find the direct discharge results mapped. Make sure to look at the uranium and nuclear substance processing facilities stack emissions record in order to obtain a complete picture.

Nuclear licensees operate across Canada. This includes uranium mines and mills, uranium processing facilities, nuclear power plants, research reactors, particle accelerators, and nuclear substances processing facilities. All of these facilities are licensed by the CNSC and are subject to strict regulatory oversight to ensure the safety of the public and the environment.

Terrestrial gamma dose rates, reported as ambient dose equivalent in the unit nSv/hr, are presented for the past ninety days to present. Data is measured in real-time, typically from the spectroscopic dosimeters of the Fixed Point Surveillance (FPS) Network. Dosimeter stations of this network are located in population centres and other strategic locations across Canada. Real-time data provides insight into typical levels and fluctuations of radioactivity in the Canadian environment and may provide early detection of sources of radioactivity other than environmental background.As a reference, the Nuclear facilities and uranium mines and mills can be found in the Open Maps catalogue and added to the Real-time Environmental Radioactivity Monitoring map using the "+" (Add layer) button of the viewer’s “Layers” panel. The ESRI REST or WMS links found in the Nuclear facilities and uranium mines and mills metadata record is what’s needed to proceed. These links can be found here: https://open.canada.ca/data/en/dataset/6478153c-829f-4649-bd52-41f63b41021f.The Nuclear facilities and uranium mines and mills dataset provided by the Canadian Nuclear Safety Commission corresponds to nuclear licensees that operate across Canada. This includes uranium mines and mills, uranium processing facilities, nuclear power plants, research reactors, particle accelerators, and nuclear substances processing facilities. All of these facilities are licensed by the CNSC and are subject to strict regulatory oversight to ensure the safety of the public and the environment.

This product provides the median of monthly maximum turbidity values (in nephelometric turbidity units) for drinking water facilities by drainage region. Turbidity refers to the relative cloudiness of water, caused by suspended particles in water. The Survey of Drinking Water Plants collected this monthly maximum turbidity data for surface water sources from facilities reporting turbidity data for at least 10 months in 2013. These facilities served 24 million people and produced 4,091 million cubic metres of potable water from surface water sources in 2013. Source water turbidity was monitored continuously at 42% of these drinking water plants in 2013, daily at 34% of plants and less frequently at the remaining plants.

The dataset represents known concentration areas of harvested or unharvested Atlantic razor clam (Ensis leei) in the Estuary and the Gulf of St. Lawrence, Quebec Region. It was created for the National Environmental Emergencies Centre (NEEC) for preparation and response purposes in case of an oil spill. Concentration areas were defined using data from Fisheries and Oceans Canada (DFO) inventories, various DFO research projects and commercial fisheries data. This layer is dependent on the inventories carried out and thus only represents the known areas of the Atlantic razor clam. This dataset does not represent the general distribution of the species nor the extent to which fishing is allowed. Most of the information comes from inventories that did not necessarily target this species, therefore its distribution is undoubtedly wider than what is recorded in the layer. In addition, the extent of shellfish beds can change over time in response to, among others, harvesting and recruitment rates. Some beds were mapped based on DFO research project data which were compiled in a benthic biodiversity Access database. Polygons drawn around these data are not precise and may be reviewed. However, the precision is sufficient for the resource protection and management needs in case of an environmental incident. Data sources and references:Anonym. 1991.

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. These indicators track facility-based releases to water of 4 substances that are defined as toxic under the Canadian Environmental Protection Act, 1999: mercury, lead, cadmium and arsenic and their compounds. For each substance, data are provided at the national, regional (provincial and territorial) and facility level, as well as by source. The indicators inform Canadians about releases to water of these 4 substances from facilities in Canada. The Releases of harmful substances to water indicators also help the government to identify priorities and develop or revise strategies to inform further risk management and to track progress on policies put in place to reduce or control these 4 substances and water pollution in general.Information is provided to Canadians in a number of formats including: static and interactive maps, charts and graphs, HTML and CSV data tables and downloadable reports. See the supplementary documentation for the data sources and details on how the data were collected and how the indicator was calculated.Canadian Environmental Sustainability Indicators: https://www.canada.ca/environmental-indicators
