The unconfined aquifer of the Belgian coastal plain consists mainly of quaternary sands which are intercalated by peat and in lesser extent clay layers. These quaternary deposits are approximately maximum 30 m thick and are situated above Tertiary clay, sandy clay and sand, dipping gently in north-eastern direction. The intercalated peat layers, the so called surface peat, influence importantly the ground water flow and the water quality distribution. During the Dunkirkian, salt water infiltrated the aquifer. Later replacement by fresh water is highly influenced by the distribution of the intercalated peat layers. This water quality distribution and the relation with the location of the peat layers are considered here by reevaluating data gathered extensively in the past and is supplemented by new observations.
