The spatial representation for Environment Regions. An Environment Region is an administrative area established by the Ministry and is an administrative area which is used to manage regional activites.

**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 - All Stations 2. Environmental Monitoring Stations - Air Monitoring (Ambient Air Site) 3. Environmental Monitoring Stations - Air Monitoring (Air Permit) 4. Environmental Monitoring Stations - Water Sites (Water Monitoring) 5. Environmental Monitoring Stations - Water Sites (Water Permits) 6. Environmental Monitoring Stations - Water Sites (Well) 7.

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.

The dataset contains projects that are currently, or have been, subject to environmental assessment review. Attributes include the project description, project phase, decision, and proponent name. This layer consists of points themed two ways: a. Project Phase- This theme consists of layers showing what phase each project is in - pre-EA, application review, post-decision, and withdrawn or terminated; and b. Project Type - This theme consists of nine layers that reflect the potential types of projects under review. This dataset is coming from the EAO Project Information Centre (EPIC) and is updated daily. For more information on any of the project points go to https://projects.eao.gov.bc.ca/.

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/

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 layer provides information on suspended particulate matter (SPM) concentrations by area. There is a natural interaction phenomenon between hydrocarbons and SPM, that creates hydrocarbon-SPM aggregates. The SPM in the water column, hence has an effect on hydrocarbon capacity to sink to the bottom in aggregate form (Gong et collab., 2014 ; Fitzpatrick et collab., 2015, cited in Centre d'expertise en analyse environnementale du Québec, 2015). Additional InformationThe suspended particulate matter data for this layer are derived from multiple sources given the need to cover the St. Lawrence portion from Montreal to Anticosti. The layer has been cut into 6 different zones. Denis Lefaivre, a researcher at Maurice-Lamontagne Institute, has provided the coordinates of the points allowing the delimitation of areas. The values in each zone are derived from different studies carried out at different times.
