Dataset Direct Download Service (WFS): Water — Zone Vulnerable to Pollution by Nitrates of Agricultural Origin in 2016 in Loir-et-Cher

The delimitation of areas vulnerable to pollution by nitrates of agricultural origin was made in the context of Decree No 93-1038 of 27 August 1993, which transposes Directive 91/676/EEC into French law. This delineation, prepared in each department and in each region by working groups, involving various departments and agencies concerned as well as representatives of the agricultural profession, is based on the knowledge of nitrate levels in the aquifers and rivers and on the levels observed during various monitoring campaigns (1992-1993, 1997-1998, 2000-2001) on a monitoring network set up for this purpose.
