The GTC System makes it possible to compile information on the records of land contaminated by industrial and commercial activities or by accidental spills. This is not an exhaustive inventory, but a compilation of cases brought to the attention of the Department. It also includes information on land that is now rehabilitated. The thematic layers of contaminated land make it possible to locate each georeferenced intervention site of the Operations Management Assistance System (SAGO) to which at least one contaminated field sheet is associated.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

This theme includes data from all metal monitoring stations in the waters of rivers in Quebec and the St. Lawrence River since 2008.
