This dataset contains the perimeters of the Areas d’Alimentation des Captages Grennelle (AAC), in the Nouvelle-Aquitaine region.
Attention: the data are not exhaustive on the Nouvelle-Aquitaine perimeter, they concern only the former Aquitaine and Poitou-Charentes regions.
The Ministries responsible for Sustainable Development, Health and Agriculture published in 2009 a list of 507 “Grenelle” catchments among the most threatened by diffuse pollution, including nitrates and plant protection products.
A catchment feeding area(s) includes specific protection perimeters and is defined, after technical study, as the area from which the water supplying the catchment(s) originates.
