CONCENTRATION OF CONTAMINANTS IN GROUNDWATER

Groundwater pollutes by leachate is the most harming ecological effect over the whole existence of a hazardous
waste landfill (HWL). To date, the percolation of bacteria and viruses through landfill leachate into the groundwater table
poses a potential risk and potential hazards towards the public health and the ecosystem, remains an aesthetic concern.
In this paper, we developed a mathematical model to study the mean concentration of contaminants (bacteria and viruses)
by leachate, employing generalized-dispersion technique. Solute transport in porous media is discussed by means of
advection - dispersion equation. The dispersion and mean concentration are obtained by Generalized-Dispersion method
. Results are obtained analytically and the numerical values are computed graphically.
