        <gco:CharacterString xmlns:gco="http://www.isotc211.org/2005/gco">L'aire d’alimentation du captage (AAC) est définie sur des bases hydrologiques ou hydrogéologiques. Elle correspond aux surfaces sur lesquelles l’eau qui s’infiltre ou ruisselle participe à l’alimentation de la ressource en eau dans laquelle se fait le prélèvement.

Ainsi, l’AAC correspond :
- pour un ouvrage de prélèvement destiné à l'eau potable en eau superficielle : au sous-bassin versant situé en amont de la ou des prises d’eau éventuellement complété par la surface concernée par l'apport d'eau souterraine externe à ce bassin versant (ex: nappe de socle ou nappe d'accompagnement des cours d'eau),
- pour un ouvrage de prélèvement destiné à l'eau potable en eau souterraine : au bassin d’alimentation du ou des points d'eau (lieu des points de la surface du sol qui contribuent à l’alimentation du captage). Les notions d’« aire d’alimentation » et de « bassin d’alimentation » de captages (AAC, BAC) sont ici considérées comme synonymes.

Dans le cas de plusieurs prises d'eau (eau superficielle) ou points d'eau (eau souterraine) proches les uns des autres, l'AAC concernera l'ensemble des prises / points d'eau de l'ouvrage de prélèvement auxquels ceux-ci sont raccordés. L 'AAC peut concerner plusieurs ouvrages de prélèvement.

Ce base de données contient les 605 AAC de la région de Grand Est (r44)</gco:CharacterString>
