In compliance to European Union directives to reuse urban wastes as secondary fuels, the aim of present work was to investigate and control the environmental impact from disposal of ashes generated by combustion of a bio-solid, an olive by-product and their blend. Two waste materials were admixed with the ash and their performance as potential stabilizers was assessed. Metals and ions leached through a soil were measured.The results showed that dissolution of some alkaline substances raised the pH of water effluents, decreasing the extractability of heavy metals from the ashes. In some cases Cr and As leached reached hazardous levels. Upon addition of waste materials to ash, the concentration of Cr in liquid extracts was reduced by 35–97%, while that of Cu and As by 100%. All heavy metal values measured in the leachates were decreased to values below legislation limits. The mineralogy, the chemistry and the pH of solids involved were key factors for the retention of elements.

According to the plans, the town of Gacko tends to be water supplied from the water reservoir Vrba located at the river Vrba. About 150 to 200 m away is located ash basin. All ash basin area is oriented to the water reservoir and leaking water going directly to the water reservoir. The leaking water has high pH value, alkalinity, high content of sodium, potassium and sulphates. There are some heavy metals, but their concentrations are not significant. The influence of those contaminated water on the lake water quality is only little evident because of the high dilution rate.
