**PLEASE NOTE:** The Environmental Monitoring System will be replaced by the EnMoDS system on March 5th, 2026. The EMS results objects will not contain new data after Feb 26th, 2026. For recent data please refer to [EnMoDS spatial locations and location groups](https://catalogue.data.gov.bc.ca/dataset/f60fa4b5-e3d0-44ad-b5d8-778d29764e34). Environmental Monitoring Stations (EMS) spatial points coverage for the Province by LOCATION TYPES. The following spatial layers reference this as a data source: 1.

Environmental monitoring locations from the [Environmental Monitoring Data System (EnMoDS)](https://www2.gov.bc.ca/gov/content?id=BDE7F9F4BC4546629582CEBC4ABC8101). These point location records show where discrete environmental monitoring may have taken place. Locations are generally in naturalized settings such as rivers and lakes, but also include anthropogenic features like wells and industrial facilities including waste discharges. Key attribute fields for filtering include, location ID, location type, location group, observation count, and most recent field visit date. Observational results for each location can be accessed from [EnMoDS Web Reporting](https://enmodswr.nrs.gov.bc.ca/) or from [EnMoDS Results Data Records](https://catalogue.data.gov.bc.ca/dataset/83a585fe-effb-48bd-8a03-d35db4eeb1bb). Information regarding changes from the Environmental Monitoring System along with other resources are available on the EnMoDS website listed in related links below.

The objective of the Independent Environmental Monitoring Program (IEMP) is to build Indigenous and public trust in the Canadian Nuclear Safety Commission's (CNSC) regulation of the nuclear industry, via an independent, technical and accessible environmental sampling program around nuclear facilities, while using CNSC resources effectively and efficiently.

The Canadian Nuclear Safety Commission (CNSC) is publishing a database with environmental monitoring results collected as part of the Eastern Athabasca Regional Monitoring Program. The samples are collected near communities located in northern Saskatchewan.

Under the Regulation Respecting the Mandatory Reporting of Certain Contaminant Emissions into the Atmosphere (RDOECA), the Ministère de l'Environnement et de la Lutte contre les Changements Climates de la Faune et des Parcs collects data on air contaminants emitted by Quebec businesses in particular. Thus, any person or municipality operating an establishment that emits air contaminants above thresholds into the atmosphere is required to report its emissions no later than June 1 of each year. This dataset includes emissions of air contaminants reported under RDOECA or voluntarily expressed in metric tons, with the exception of dioxin and furan emissions, which are expressed in metric tons of toxic equivalents.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

This dataset provides the background radiation dose results from Health Canada’s Canadian Radiological Monitoring Network (CRMN) monitoring sites. More information about the CRMN network can be found on the Health Canada website (see link below).This background radiation data contains both “monitoring” and “transit” dosimeters starting in 2016. The historical background radiation dose data can be found on the Open Data portal. A transit dosimeter is sent along with the monitoring dosimeter to determine if there is a significant dose recorded by the dosimeter while it is in transit to the sampling station. The transit dosimeter is shipped out with a station monitor, and shipped back with the station monitor from the previous quarter. The monitoring dosimeters are deployed over a longer time (around three months) than the transit dosimeters (around 3 weeks). This difference largely explains the lower recorded dose values for the transit dosimeter. The results provided for the monitoring and transit dosimeters are expressed as ambient dose equivalent to a cesium source, in units of millisieverts (mSv). The measured dose rate is reported in mSv/day. The external dose can be attributed almost exclusively to natural radiation (of terrestrial and cosmic origin) with fluctuations based on several factors including location, soil characteristics, and seasonal changes. The map shows the approximate sampling location for each monitoring station. Stations are found within the associated location range.

The Canadian Nuclear Safety Commission (CNSC) and Environment and Climate Change Canada (ECCC) are publishing databases with effluent and environmental monitoring results from nuclear facilities located along the Ottawa River watershed as part of the Regional Information and Monitoring Network (RIMNet) for the Ottawa River Watershed Basin initiative. The facilities included are Chalk River Laboratories, Nordion Canada Inc., SRB Technologies Canada Inc., and Nuclear Power Demonstration Waste Facility. The initiative was developed to address questions and concerns expressed by members of the public and Indigenous Nations and communities about the availability of publicly accessible environmental monitoring data in the Ottawa River Watershed Basin. More information about the initiative is available here: https://www.cnsc-ccsn.gc.ca/eng/resources/environmental-protection/rimnet/ This dataset contains effluent and environmental monitoring results from Chalk River Laboratories, Nordion Canada Inc., SRB Technologies Canada Inc., and Nuclear Power Demonstration Waste Facility. All of the effluent and emissions releases to the environment in this dataset are below the CNSC licensed release limits. All of the environmental monitoring results in this dataset are below environmental quality guidelines. More information about CNSC staff’s assessment of these facilities are found in CNSC staff’s regulatory oversight reports: https://www.cnsc-ccsn.gc.ca/eng/resources/publications/reports/regulatory-oversight-reports/
