Abstract

Two sets of soil lysimeters were amended with solid and liquid olive mill wastes and the composition ofleachate was analysed. Five treatments were carried out using: olive mill wastewater (OMW) at twodifferent rates (80 and 320 m3/ha); OMW pre-treated by catalytical digestion with MnO2; compost obtainedby exhausted olive pomace; freshwater as the control. Electric conductivity, pH, potassium, totalpolyphenols and nitrates were monitored in the leachate as indexes of potential groundwater contamination.The study demonstrated that the impact of all the selected amendments on groundwater was theminimum. OMW was safely applied to soil even at four times the rate allowed by the Italian law, and pretreatmentby catalytical digestion was not necessary to further reduce the impact on groundwater. Theapplication of olive pomace compost was equally safe.
