In April 2025, we hosted another group of students from Spain. We conducted a workshop on the Kamniška Bistrica River using GLOBE hydrosphere protocols and determined the basic physical and chemical properties of water.

In April 2024, we hosted a group of students from Spain, who at their school also deal with a field that is also related to degraded areas. On April 19 2024 we visited some brownfield sites near Domžale, which we had known since our visit in 2019 and 2020.  Students also did chemical analysis of water in Rova clay lakes using suitcases for analytical chemistry. The temperature of the sample of water was measured and the content of ammonium, nitrite, nitrate and phosphate ions and the pH and total hardness were determined.
