In Rich Waters, we test different methods to reduce this internal load. The results will contribute to better understanding of the most effective measures to overcome the problem.
Tools to combat internal loading
Development of tools to combat internal phosphorus loading in lakes and coastal waters.
Restauration of Lake Öljaren
Environmentally friendly removal of phosphorus-rich sediment from Lake Öljaren. The sediment will be re-used as fertilizer in agriculture.
Treatment of Lake Norrviken
Performing a full treatment of stop internal phosphorus loading in Lake Norrviken, including an evaluation of possible adverse effects on contaminant levels in fish.
