Kalium- en nitraatproblemen in het captatiegebied van het drinkwaterproductiecentrum de Blankaart, West-Vlaanderen
The Environment Inspection Section, West Flanders Local Service has jurisdiction over the Blankaart water production centre, which is completely fed by surface water from the IJzer river, the Blankaart pond and the Koevaardeken (Belgium). The quantity of drinking-water daily distributed in the water supply system ranges from 7.200 to 67.000 m3. Increasing pollution and seasonal differences in quality and quantity render a reservoir (3.000.000 m3 capacity) absolutely necessary. The rising potassium and nitrate content of the reservoir water led the drinking-water collection company to request the Environment Inspection Section to conduct an exhaustive inquiry into the causes of this pollution. The potassium pollution turned out to be completely caused by the waste water discharge of an important company. Stopping the potassium discharge turned out to be impossible on the short term but initiatives on the European level will eventually cause the norm as to the potassium content of drinking-water to be adapted. The causes of the nitrate pollution are diffuse and are fully due to agricultural activities, being the excessive manuring of lands and pastures, on the one hand and the manure discharges on the farms, on the other. Our Local Service intensively scanned the catchment area of the water production centre and consequently imposed various preventive measures. Offences have been reported to the Public Prosecutor
