Stockholm archipelago water quality 2025: stable with local setbacks

The Stockholm Vatten och Avfall AB board is proposed to approve a report on the state of the Stockholm archipelago in 2025. This report, based on water chemistry and plankton analyses, describes how the archipelago's water environment is affected by outflows from Lake Mälaren and discharges from the Bromma, Henriksdal, and Käppala wastewater treatment plants. It indicates generally stable conditions during 2025, with localized deviations in oxygen and nutrient levels, and a decline in ecological status in certain areas.
This summary is based on the meeting agenda. We'll update when the minutes are published.
