Continental Surface Water Quality (STQ) Quality Stations — Whole France

The measuring station is the site located on a hydrographic entity (streams, lakes, canals, etc.), where measurements or sampling are carried out for physico-chemical, microbiological, etc., in order to determine the quality of aquatic environments at that location. This is a volume in which measurements can be made at different points deemed to be consistent and representative of the station. This information is administered by the Water Agencies and the Water Offices and is the responsibility of the contracting authority(s) of the measuring networks or uses to which the station is attached. This benchmark incorporates the measuring points AEP (Poilable Water Supply).
