In the global race of development, a huge amount of wastes having different characteristics and potential for environmental pollution are generated from various activities such as manufacturing, mining, processing, treatments, agriculture, etc. Considering the pollution threats to all three components of the environment (air, water and soil), it is highly essential to assess the levels of pollution associated with these wastes so that suitable remedial measures can be adopted. When untreated hazardous wastes are disposed on the ground or in the landfills, there is always a possibility of groundwater contamination due to the transport of leachate generated from the disposed wastes. In order to predict the groundwater pollution levels at different locations of the aquifers and at different times, several models suited to the characteristics of the concerned hazardous wastes and aquifers have been widely reported in literature. This paper presents a comprehensive literature review on groundwater contamination by hazardous wastes and its different aspects, including the types of hazardous contaminants, aquifers, contaminant transport mechanisms, contaminant transport modeling, software available for modeling contaminant transport in aquifers, groundwater sustainability and a case study on groundwater quality prediction.

在全球发展竞赛中，制造，采矿，加工，处理，农业等各种活动产生了大量具有不同特性和潜在环境污染的废物。考虑到对环境所有三个组成部分的污染威胁（空气，水和土壤），评估与这些废物相关的污染水平非常重要，以便可以采取适当的补救措施。当未经处理的危险废物被丢弃在地面或垃圾填埋场时，由于处置的废物产生的渗滤液的运输，总是存在地下水污染的可能性。为了预测含水层不同位置和不同时间的地下水污染水平，在文献中已经广泛报道了几种适合于有关危险废物和含水层特征的模型。本文就危险废物对地下水的污染及其不同方面进行了全面的文献综述，包括危险污染物的类型，含水层，污染物运移机制，污染物运移建模，可用于对含水层中污染物运移进行建模的软件，地下水可持续性和案例研究。关于地下水质量的预测。
