In the paper it is presented first of all the investigations and the carried out studies for founding the rehabilitation solutions of the decantation pond made from washing out, transport and carbonation of the sugar beet which has the code 02 04 01 in the European Catalogue of wastes. There are presented, shortly, the results towards the possibility of flooding the terrain, the hydrogeological conditions, the pedological conditions and the most important issue the dates towards the pollution with heavy metals, organohalogen compounds, polycyclic aromatic hydrocarbons and polychlorinated biphenyls. In order to evaluate the pollution it were taking soil assays from three points of the location and they were chemical and physical analyzed. The carried out determinations showed that the Romanian limit values are not gone beyond the limit towards the pollution containing ubstances for the agriculture. On the other hand, it were made investigation towards the fertility level of the soil from the location. On these lines, it is also presented the reliability study made for the evaluation of the fertility and of the favorable conditions for using the surface of the lake as an agricultural terrain. The studies shows that there are some limitations towards using it as an agricultural terrain most of all towards pedological and fertility reasons. Having all these tudies as a starting point in the paper it is presented the set of measures in order to use the terrain in agriculture. The proposed measures are enduring measures (it is stimated the period of rehabilitation 3… 4 years) which include: the degrease of he soil humidity throughout temporally works: leveling and modeling of the surface, making a ploughing for turning the soil, discing of the ploughed surface, the melioration of the soil fertility and of the soil structure throughout the cultivation of fertility plants which are covered during the autumn by the ploughing.
