Groundwater contamination studies‐the state‐of‐the‐art

Abstract

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.

Isolated buoyant convection in a two-layered porous medium with an inclined permeability jump

“…Through this work we indirectly attempt to address some of the key uncertainties in the field of groundwater contamination (Khondaker, Al-Layla & Husain 1990) and acid gas injection (Bachu et al 2008 b ). These uncertainties include predicting the short- and longer-term dynamics, i.e.…”

Transport and fate of chlorinated hydrocarbons in the vadose zone — a literature review with discussions on regulatory implications

“…A number of informative reviews of solute transport modeling have been published in recent years (Addiscott and Wagenet, 1985;Bonazountas, 1991;Hem and Melancon, 1986;Jury and Fliihler, 1992;Jury and Ghodrati, 1989;Khondaker et al, 1990;Loague and Green, 1991;Nielsen et al, 1990;Naymik, 1987;van Genuchten and Shouse, 1989).…”

Beneficial effects of plants in the remediation of soil and groundwater contaminated with organic materials

“…The literature on bioremediation of petroleum-contaminated soil has been reviewed by Lee et al, 91 Sims et al, 144 -145 Erickson et al, 45 Khondaker et al, 81 Mercer and Cohen, 112 and Testa and Winegardner. 153 The proceedings of several conferences on petroleum-contaminated soils have been published.…”
