在这项工作中，研究了一个使用了10年的不受控制的橄榄油厂废水处理场地。一旦关闭，土壤表面沉积的固体废物就被清除了。为了评估对土壤特性的影响，将受影响地区的土壤剖面的形态学方面和分析参数与位于垃圾填埋场附近的对照土壤进行比较。确定了下层土壤中的残留污染水平。结果表明：废水入渗导致土壤中碳酸盐的溶解和重新分布，改变了土壤的pH值、电导率、养分含量、酚类化合物和生物活性。及时清除废物、自然浸出和生物活性导致电导率和酚类化合物的有效降低，尽管残留水平即使在2年后也很重要。
A location used for 10 years as an uncontrolled olive oil mill wastewater disposal site is studied in this work. Once it was closed the sedimented solid waste on the soil surface was removed. In order to evaluate the influence upon soil characteristics, morphological aspects and analytical parameters of a soil profile from the affected zone are compared to those of a control soil located near the landfill. The residual contamination levels in the underlying soil are determined. The results show that the wastewater infiltration in the soil has caused carbonate dissolution and redistribution and modifications in pH values, electrical conductivity, nutrient contents, phenolic compounds and biological activity of the horizons. Removal of waste, natural leaching and biological activity, in time, led to an effective decrease in electrical conductivity and phenolic compounds, although residual levels can be important even 2 years later.
