Abstract:
We are modelling the leaching of contaminants from the unsaturated soil towards shallow groundwater in soils exposed to emission from construction products or contaminated soil. Using a solute transport model in combination with a geochemical speciation model we will estimate the concentration in the shallow groundwater over time for the elements As, Ba, Cd, Cr, Co, Cu, Hg, Pb, Mo, Ni, Sn, V and Zn.
With this study we investigate the relation between sustainable soil management, including the application of construction products and contaminated soils, and the effects for shallow groundwater quality. Using knowledge and models from current and future work we will be able to (1) assess the mobility of present contaminants in soil and (2) the mobility of input of contaminants due to (diffuse) emission from construction products. In this year, our study will provide instruments to predict leaching from either soils under ambient conditions, or soils which are displaced or applied in construction works. Based on these predictions a risk assessment will be carried out incorporating current soil and groundwater quality and existing risk levels.
