Abstract

Pollution can occur in any environment, but the way the pollutants spread over depends on the environmental features. Some pollutants remain more or less confined to the contamination site, others do not. This paper proposes a territory zoning showing lands susceptibility for possible groundwater pollution through leaching in Romania, if pollution occurs. The method uses a GIS technique and takes into account soil permeability and texture, relief type, depth to groundwater and climatic water deficit. Six land susceptibility classes were obtained for the whole territory. The highest vulnerability to groundwater pollution was assessed for the most permeable sandy soils, or near - river soils, whereas the most resilient environment was assessed for the low permeable clayey soils. This land classification is aimed at drawing attention to stakeholders in order to rank and take the most appropriate measures to prevent and control pollution, if occurring. The regions that are most vulnerable to pollution should be managed with more care than the most resilient regions. If global warming continues, more severe rainfall events are expected to happen, thus enhancing the leaching of pollutants toward groundwater, specifically for the most vulnerable classes.

评估土地对浸出可能造成的地下水污染的敏感性&以罗马尼亚为例
污染可能发生在任何环境中,但污染物的传播方式取决于环境特征。一些污染物或多或少地被限制在污染现场,而另一些则没有。本文提出了一个区域分区,显示如果罗马尼亚发生污染,土地对可能的地下水浸出污染的敏感性。该方法使用GIS技术,并考虑了土壤渗透性和质地、地貌类型、地下水深度和气候缺水。获得了整个领土的六个土地敏感性等级。透水性最强的沙质土壤或近河土壤对地下水污染的脆弱性最高,而透水性较低的粘性土壤对最具弹性的环境进行了评估。这种土地分类旨在引起利益相关者的注意,以便对污染进行排名,并在发生污染时采取最适当的措施来预防和控制污染。最容易受到污染的地区应该比最有弹性的地区更加小心地管理。如果全球变暖持续,预计将发生更严重的降雨事件,从而加剧污染物向地下水的浸出,特别是对最脆弱的阶层。
