Abstract

Community waters are affected by eutrophication of different severities. Overfertilization of waters in Denmark, Italy and Netherlands constitutes a serious pollution problem. In other Member States it is a localized phenomenon, although it represents a significant water degradation problem due to impairment of drinking water supplies. Point sources account for 70% of total P load to Community surface waters. Phosphates from municipal sewages contribute 40% of total loading, of which 40-50% is detergent phosphate. Agricultural diffuse sources represent 17% of total theoretical phosphorus load. To provide realistic management plans, basic and minimum water quality objectives are suggested. Possible regulatory measures for diffuse source control are presented. Strategies undertaken in Member States to counteract phosphorus from municipal point sources range from enforced reduction of detergent phosphates to efforts to discourage P replacement substitutes, such as NTA, which are not entirely safe. The selection of the method can only be achieved after making comprehensive cost/benefit and risk/benefit evaluations.
