Monitoring of contaminants of emerging interest in surface water

This theme presents the location of samples of contaminants of emerging interest (CIE) carried out by the Main Directorate for the Quality of Aquatic Environments (DPQMA) as part of its work since 2000.

Each station is accompanied by a link in the attribute table allowing the reader to access an Excel file presenting the concentrations of CIE detected, the list of CIE analyzed at least once at the station, the list of reports produced from the samples taken at the station, as well as information on surface water quality criteria for the protection of aquatic life.

The dataset on contaminants of emerging interest also includes a layer of polygons presenting the drainage areas of some of the stations and a data table including the compilation of land use by category for the last year available at the time the data was generated. The drainage areas and the land use table are linked to the sampling stations based on the BQMA station number.This third party metadata element was translated using an automated translation tool (Amazon Translate).
