Résumé
In Brittany, France, intensive farming operations have produced a so-called "diffused" pollution of water resources. Leaving aside this phenomenon's scientific aspects, attention is turned to the way social and political circles see and handle this sort of pollution, and toNBthe strategies which this "diffuse" pollution from farming allows for. An examination of public actions shows how the agricultural "profession" tries to remain vague about this question in order to put off the moment when it reaches the public agenda, how it exploits the difficulty of finding indicators for allotting responsibility and how it turns this "diffused" trait into an essential property of this pollution. Actions by public authorities do not simply inherit this pre-established definition but, instead, help turn this agricultural pollution into a "diffuse" sort of pollution.
