Additional studies are used to strengthen the analysis of the state of health of Lake Geneva

Given the large number of parameters andand the limited resources available to study themto study them, it is not possible to monitor to monitor everything, in all compartments, every day of the year.

In order to find a reasonable balance between the informationbetween the information that can be and the cost of monitoringthe CIPEL relies on on the complementarity between a regular regular and annual monitoring programme (temperature, phosphorusphorus, oxygen, plankton, micropollutants in water, etc.) micropollutants in water, etc.) and complementary, more specific (aquatic vegetation, micropollutants in fish, musselsmicropollutants in fish, mussels or sediment, etc.), in order toments, etc.), in order to consolidate a global picture of theof the state of health of Lake Geneva

Scientific studies carried out by the CIPEL :

Sediments

Studies of sediments in Lake Geneva to measure changes in nutrient (especially phosphorus) and metallic micropollutant levels, as well as the presence of certain organic micropollutants and even microplastics.
organic micropollutants and even microplastics.

The flesh of the fish

Analyses of micropollutants in fish flesh to monitor the evolution of contamination (PCBs and mercury) in the environment and analyses of microplastics to extend the studies already carried out on plastic fragments in the sediments of Lake Geneva.

Wastewater treatment plants

Modelling study of micropollutant inputs to wastewater treatment plants in order to draw up different reduction scenarios depending on the type of treatment.

Invasive alien species

Inventory of exogenous invasive species on the shores of the lake to record the presence and location of 12 species considered the most problematic.

Plant protection products

Characterisation study of the risks of transferring phytosanitary products of agricultural origin to surface waters.

Macrophytes

Inventory of the macrophytic vegetation of Lake Geneva to monitor the evolution of the quality of the environment.
