The method for the dynamical calculation of leaching and run-off of heavy metals from agricultural and natural soils has been improved on the basis of the most recent measurements and knowledge. The number of metals has been expanded to 14 and now includes next to the metal included previously (Cd, Cu, Ni, Pb, Zn) also models for As, Ba, Co, Cr, Mo, Sb, Se, V, and U. To this purpose Freundlich partition relations have been derived for these 14 metals. The vertical distribution of the reactive metals content in soil used to calculate the solution concentration has been revised using recently acquired data and auxiliary variables include the P content in the soil and the amount of Fe and Al oxides. Finally also the regional schematization of concentrations in the upper groundwater has been revised and extended with information on the 9 new metals. In the context of the national and international obligation to report the emissions and pollution of surface water, the diffuse source leaching and run-off of heavy metals from the soil to the surface water has been calculated using the revised model. For consistency, the data used for and results from the National Water Quality Model for nutrients have been used
