Dataset Description
The National Pollutant Release Inventory (NPRI) is Canada's public inventory of pollutant releases (to air, water and land), disposals and transfers for recycling.
The files below contain a map of Canada showing the locations of all facilities that reported direct releases to land to the NPRI. The data are for the most recent reporting year, by reported total quantities of these releases.
The map is available in both ESRI REST (to use with ARC GIS) and WMS (open source) formats. For more information about the individual reporting facilities, a dataset is available in a CSV format.
