TO KNOW AND IMPROVE THE QUALITY OF MARINE WATERS AND THAT OF OUR CANALS AND PORT BASINS
Water quality monitoring
Major water quality, dredged sediment and biodiversity monitoring programmes are being implemented. They allow us to better assess the impact of our activities on the aquatic environment.
Various parameters representative of water quality are monitored (temperature, dissolved oxygen, suspended solids, nitrates, phosphates, etc) at the rate of 5 campaigns per year.
The general water quality is improving thanks in particular to pollution reduction efforts undertaken by the area's industrialists and local authorities. To go even further, the GPMH, with the support of the Seine Normandy Water Agency, a few years ago launched its master plan for its sanitation system to monitor more precisely the flow of pollutants in basins and canals and reduce them. Action plan for 2016.
Pollution monitoring and alert networks
In order to manage possible cases of accidental pollution, the GPMH has an anti-pollution intervention plan which aims in particular to specify the organization of the response and the role of each participant.
