Maps of reporting facilities – total releases to water

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 surface waters 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.

Please consult the following resources to enhance your analysis:

国家污染物排放清单（National Pollutant Release Inventory，NPRI）是加拿大面向公众的污染物排放（涵盖大气、水体与陆地三类途径）、污染物处置及循环利用转移情况的公开统计清单。

下述文件附带加拿大地图，标注了所有向NPRI报告直接向地表水排放污染物的设施的点位信息。本数据集基于最新报告年度内各设施上报的直接地表污染物排放总体量统计生成。

该地图提供ESRI REST（适配ARC GIS使用）与WMS（开源）两种格式供获取。如需查阅各报告设施的详细信息，可获取CSV格式的配套数据集。
