One of the key issues in the basin is to limit soil erosion
• suspended solids due to soil erosion, in particular in arable farming areas (Brie)
and winegrowing regions (Champagne and Chablis), silt up riverbeds and carry
with them pesticides and nutrients,
• the turbidity of groundwater in karstic zones (Pays de Caux) causes problems for
drinking water supply.

One of the key issues for the basin: control diffuse pollution
• nitrates of agricultural origin contribute to eutrophication of the coastline and excessive
growth of algae, some of which are toxic for bathers and consumers of shellfish;
• nitrates and pesticides compromise the production of drinking water, on an occasional
basis from surface water and on a long-term basis from groundwater.

One of the key issues for the basin: limit eutrophication
• phosphorus is the main factor in the eutrophication of water courses;
• nitrates are the major factor in eutrophication of the coast.
