Past mining activities in the Almasu Mare area have led, along the time, to environmental pollution, especially of the soil. Rades gold mine is a source of negative impact today. The improperly mine closure gives the possibility of theleaks from the inside of mine to arrive at surface, creating large imbalances in soil and not only. Also, the sterile dump which is very near of Rades mine is a concern for the environment from Almasu Mare because it is not subject to ecological coating process, and the wind and rain can lead the particulates on the surface of the dump at long distances. In order to analyse the current situation of soil in Rades mine area some physico-chemical analysis were performed. The physico-chemical analysis consisted in determination of the humidity content, the structure, texture and pH of the soil. The results of experiments related to the humidity showed that the soil humidity in the forest (18.34%-34.77%) was higher than the humidity determined from the surface tailings of Rades dump (14.15% - 22.39%). The soil in forest area is partially structured and the dump material is poorly or very poorly structured. The dump material and soil texture is largely rough and the pH of tailings material taken from the Rades dump surface was in the range of 3.4-4.8 pH units and in the forest was in the range of 5.3-5.6 pH units.
