摘要：Traditional mining operations have not taken into consideration long - term negative impact on the environment, because in the beginning of these activities, there were no regulations or s tandards to guide these works and neither concept s of regeneration and restoration of affected sites have not existed. The disturbance of surface and groundwater resources has resulted in a number of serious environmental issues, such as acid mine drainage s, erosion/sedimentation, contamination of groundwater and surface water, chemical agents and air pollution. Now, beyond their damaging impact on the environment, the abandoned mine sites register several serious threats to public health and safety. One of many problems that can may be present at an abandoned mine area near the human settlements is the drinking water supplies contaminated due to pollution with heavy metals or with chemical agents used in mining process. This issue is present in northwester n Romania due to the mining activity which dates back to the second half of the eighteenth century. This paper presents the simulation of the trajectory of the inorganic pollutants (Cd, Pb, Zn, Cu and Cr) in surface waters for a period of four years (2011 - 2014) which is essential to control the contaminants, because they are non - decaying substances. The simulation has generated charts highlighting the evolution of heavy metals on horizontal and vertical direction along the riverbed Socea on an area of 3 km. The Socea Valley is situated in the Tarna - Mare village, Satu Mare County
