Decreasing hazardous pollutants in wastewater

Using source tracking to regulate industries

Several years ago Gladsaxe Municipality near Copenhagen, Denmark had a number of wastewater pollution hotspots. Knowing the source of the pollution was vital for Gladsaxe Municipality to address the problem. To assist them, we set up monitoring programmes in three industrial areas in the Municipality. This enabled Gladsaxe to identify the responsible industries and regulate them. This in turn led to a reduction in the concentration of most metals as well as hazardous and environmentally harmful substances in the wastewater going into the sewer system.
