Description
Summary:For modelling of the pollutants transport process in aquifer a very important aspect has the analysis of aquifer pollution with heavy metals. The surface complexation process of heavy metals on the grains of porous-media is reversible similar to the adsorption-desorption in transport processes, in aquifer pollution, but strongly dependent of pH value. High pH values determine increasing heavy metals complexation and consequently decrease their concentration in the groundwater. Decreasing pH value leads to liberation of heavy metals from the formed complex and so an increased concentration of heavy metals in the groundwater appears. This paper presents the results obtained by using a numerical experiment using PhreeqC and PMWIN software package for the spreading of the heavy metals pollution in the aquifer of an ash and slug dump, as pollution source, near village Utvin, Timi$ County, Romania.
