Abstract: ► Groundwater geochemistry data set for a waste trench in Chernobyl zone is analyzed. ► Leaching losses from the trench are governed by degradation of buried organic matter. ► Geochemical impacts decrease in time due to humification of the organic matter. ► Additional factor controlling leaching losses is nutrient element uptake by vegetation. ► Evolution of geochemical regime favors attenuation of groundwater migration of ⁹⁰Sr.
