Groundwater Contamination Studies — The State-of-the-Art

With the increasing sense of awareness about our environment and the recognition of the need for its protection, the study of solute transport related to groundwater contamination has become the focus of numerous researchers. Different investigators approached the problem from many view points, and the resulting achievements are so extensive and scattered that it seems essential to inventory the completed works. This paper presents a systematic study of the available theoretical and experimental works. A complete picture of the present status of the problem is also provided. Issues that remain obscure or unaddressed by the current day investigators are pointed out to facilitate future research directions and/or alternatives to advance technology for a greater understanding and more comprehensive analyses of the solute transport phenomena related to groundwater contamination.
