Coastal waters are seawater between the ocean waters and the land, and are therefore under greater influence from inland waters (rivers, creeks, marshes, aquifers...). This makes them highly variable and heterogeneous in terms of both space and time. The Agency controls their quality, mostly on the basis of two European directives: the Water Framework Directive (Directive 2000/60/EC) and the Bathing Water Directive (Directive 2006/7/EC).

In compliance with the WFD, the ecological and chemical status of water bodies is assessed all year round, based on various biological and physicochemical indicators and toxic substances, by means of a monitoring and control plan prepared by the ACA. The Bathing Water Directive uses microbiological indicators and other parameters to determine the quality of a bathing area. This Directive is applied only during the bathing season (June-September).
