Sensitivity indicator of groundwater bodies (regions Brittany and Pays de la Loire) (WFS service)

Service WFS — The groundwater body sensitivity indicator on the territory of the West RID measures intrinsic vulnerability (“pollution propagation speed to [...] underground water table” and water table defence capability) and is calculated from the crossing for each polygon (corresponding to the finest hydrogeological entity on a column of several hydrogeological entities) between the hydrogeological entity medium (porosity, crack, fracture, permeability), the nature of the hydrogeological entity (aquifer, semi-waterproof or waterproof unit), the state of the tablecloth (free, semi-captive, captive) and efficient rain (unprecise because only data collected at the departmental level).
