VIDEO from TRUST ALUM: Restoring Lakes, Building Trust

The TRUST ALUM project brought together 9 dedicated partners from Latvia, Estonia, Lithuania, and Sweden with one shared mission – to reduce historical phosphorus pollution in Baltic lakes and build trust in sustainable restoration methods.

The project video takes you on a journey from the project’s launch to the culmination of years of work. You’ll see scientists monitoring lakes in all seasons, collecting samples, and modelling the exact PAC dosage needed for safe and effective treatment. The story unfolds with meetings, workshops, and open conversations with local communities, ensuring transparency and tackling misinformation about ALUM use.

Central to the project was the pilot treatment at Lake Velnezers, Latvia. After more than a year of careful monitoring and planning, the team applied the ALUM method, used successfully in Sweden for nearly 60 years, to bind excess phosphorus permanently in the lake sediments. The process was carried out with precision and care, balancing innovation with environmental safety.

Beyond the science, TRUST ALUM created a cross-border expertise hub, connecting stakeholders from ministries, municipalities, universities, and NGOs. The video showcases how this network fosters knowledge exchange, builds capacity, and ensures the lessons from Lake Velnezers can inspire restoration efforts across the Baltic region and beyond.
