Simple download service (Atom) of the data package: Partial New-Aquitaine: Drinking Water Captures and Capture Food Areas (AAFC)

This data set contains the following datasets: location of priority catchments, municipalities concerned by one or more priority catchments, perimeters of the Grenelle and Priority Areas of the New Aquitaine region. Please note: partial data on the perimeter of New Aquitaine, consult the metadata sheets of the datasets. 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. Spread across France, the “priority captures” were identified through a local consultation process, based on three criteria: — the state of the resource vis-à-vis diffuse pollution (mainly nitrates and pesticides), — the strategic nature of the resource — the desire to regain some abandoned captures. A priority abstraction may be made up of several water collection structures (catching field): the term therefore refers to a drinking water abstraction territory rather than a single point. In response to the requirements of the Water Framework Directive, the Water and Aquatic Environments Act of 30/12/06 strengthened the control mechanisms for diffuse pollution of agricultural origin by creating protection zones for catchment feeding areas. The implementation of this new resource protection system leads to the delineation of catchment foraging areas (AAFCs, sometimes also referred to as catchment feeding basins or LACs) that include AAFC protection areas. For surface water abstraction, the AAFC is the sub-watershed located upstream of the intake. For groundwater, a common national AAFC delineation methodology has been proposed. At the right of the methodological guide produced, the supply basin of an underground catchment is defined as the location of the points on the surface of the soil that contribute to the feeding of the catchment. Some catchment foraging areas are identified as priorities within the Water Management and Management Master Plans (WMPs) and measurement programs. A AAFC is thus defined, after a technical study, as the area from which the water supplies a close catchment or several catchments.
