Groundwater is the major source of drinking water. However, groundwater pollution is a major problem in many parts of the world, including India, and need urgent attention for remediation. Groundwater is being polluted due to several industrial, agricultural and other manmade sources over the past few decades. There, mediation of a contaminated site is a major challenge. Two commonly used techniques for groundwater remediation are: pump and treat and bioremediation. Further, an effective groundwater remediation study requires the assessment of location of contaminant plume and its movement of the plume with respect to space and time. Thus, simulation optimization tools are essential for optimal designs. Generally, the groundwater flow and transport is analyzed using a simulation model, which is further linked with an optimization algorithm to identify the best management strategies with the considered objective and constraints. For most of the remedial designs, the simulation is carried out using numerical methods such as Finite Difference Method (FDM), Finite Element Method (FEM). Recently, mesh free methods such as radial point collocation methods (RPCM) and Mesh free Local Petrov Galerkin (MLPG) methods are developed for the simulation.

In this lecture, various issues of groundwater, pollution management, and remediation will be discussed. Further, the application of simulation optimization models for groundwater pollution management will be demonstrated. The numerical simulation models like finite element and mesh free methods will be demonstrated. For optimization, Particle Swarm optimization and other techniques are used. Results from the proposed model demonstrate the effectiveness of simulation optimization models for groundwater sustainable management design plans. From his coupled approach, a strategy can be obtained. It can help in identifying the critical variables hat limit the results. Alternative scenarios can be simulated and changes can be proposed accordingly. These studies help in evolving appropriate guidelines and control systems for end users.
