Protection Areas for Class A4 easements (Non-Domanial Water Course) in the Somme __Origin__ Perimeter resulting from studies related to each capture. The objective is to reclaim the quality of the water resources of degraded catchments and to complement the protection perimeters (mainly dedicated to combating occasional and accidental pollution) by implementing complementary actions aimed at diffuse pollution. This process of reconquest consists of deploying on each of these catchments a methodology adapted to the chalk aquifer of the hydrogeological basin, and which is organised around the following phases: preliminary studies for the definition of the catchment water supply area and its intrinsic vulnerability; diagnosis of the pressures exerted by all activities on the feeding area (agricultural, domestic, artisanal, industrial, community pressures) drawing up an action plan to reduce these pressures, with quantified targets; annual monitoring of the action plan. Nine catching fields have been identified as priority areas in the Somme. __Partner organisations__ DDTM Somme __Links annexes__ * [XML metadata view](http://ogc.geo-ide.developpement-durable.gouv.fr/csw/all-dataset?REQUEST=GetRecordById&SERVICE=CSW&VERSION=2.0.2&RESULTTYPE=results&elementSetName=full&TYPENAMES=gmd:MD_Metadata&OUTPUTSCHEMA=http://www.isotc211.org/2005/gmd&ID=fr-120066022-jdd-1939d4cd-84e1-482f-8e48-c489f4675527) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/bfc4b8b6698b286b456125a145c843ba79b3f9d5)
