in-situ bioremediation

What is it about?

The in-situ bioremediation process of groundwater contamination is explored using the developed PCM-BIO-PSO multi-objective model with different strategies of minimization of cost, number of wells and time of remediation. The proposed model can be effectively used for the in-situ bioremediation design of contaminated sites.

Why is it important?

The requirement of groundwater increases with the increase of population, industrialization, agriculture, and navigation. The groundwater quality has also become a major concern in terms of color, odor, taste, and hardness. The conservation of the quality and quantity of the groundwater requires supreme priority. Any groundwater contamination study involves identification of the source of contaminant, the movement of the pollutants in the groundwater environment once they are introduced, proper management of resource utilization, and preventive measures to ensure suitable development and remediation of polluted sites.

In this study, an S/O model is presented using MFree PCM for the simulation of coupled groundwater flow and transport and PSO for getting the optimal solution for efficient in-situ bioremediation. Two strategies of cost minimization with number of wells and cost minimization with time of remediation are considered with different population sizes. The proposed model is applied to a case study to demonstrate the applications of the developed model.
