Abstract
The rate of movement of certain potential pollutants (e.g. heavy metals and organic carbon) found in municipal solid waste (MSW) landfill leachates is correlated with certain measurable broad parameters of both the leachate and soil. Those most prominent leachate characteristics fall into broad categories such as total organic carbon compounds (TOC), pH, and concentration of soluble common salts and some naturally occurring metals, notably iron. Usually, the lower the pH level and higher the concentration of the other constituents, the more rapid is the movement of the pollutants through soil. Therefore the behavior of MSW leachate with respect to its influence on attenuation of heavy metal migration through soils is not the same generated from freshly deposited waste as from that deposited longer.
