Abstract
In this paper, a parametric study of an insitu groundwater disinfection procedure is presented. The developed model is based on injecting disinfection material that helps through chemical reactions to reduce the contaminant concentration. The study region is a hypothetical area of regular shape of dimension L by 0.5L. The two-dimensional unsteady state mathematical modeling includes a simultaneous of the three boundary value problems, namely the groundwater flow, the contaminant transport and the disinfection material transport. A point source of the contamination of 1000 units ’ concentration is assumed to be existing in the domain and located at the region centroid. The main objective of the mathematical model is to investigate the factors that influence the effectiveness of the remediation process. It was concluded that the location of the source of decontamination with respect to the source of contamination plays a significant role on the remediation process. Moreover, both the heterogeneity and anisotropy of soil enhances to a great extent the remediation processes.
