Phosphorus discharges into surface waters from point sources
|Updated: 1.12.2017 - Next update: 3.12.2018|
Point sources, such as industry and municipal wastewater treatment plants, have succeeded in considerably reducing the flow of nutrients into water bodies since the 1980s. The development was particularly rapid in the 1990s when, for instance, phosphorus discharges from industry declined by 67%. Although the pace has slowed slightly in the 2000s, reductions continue.
This success has been achieved by improving industrial processes and by boosting industrial and communal wastewater treatment. Better feeding techniques and reduced fish production in Finnish fish farms have contributed to smaller nutrient leakage from fish farming.
