Against that background the Federal Ministry for Education and Science (Bundesministerium für Bildung und Forschung – BMBF) initiated a research association named “prognosis of the seepage based pollutant impact into the groundwater (seepage water prognosis)” to predict groundwater impact, coming from low polluted “recovery-waste”, recycling products or contaminated material.
