ABSTRACT

 

Percolation test is a very important test which measures the movement of fluids inside the soil. Studies on percolation through different soilmass remain an important factor in the design of onsite wastewater and stormwater disposal facilities. Moreover, results obtained from the percolation tests are very useful in the modeling of groundwater pollution and subsurface leachate contamination. However, it is worth mentioning that these results depend upon a numbers of parameters like the type of fluids, soil properties, drainage and climatic conditions etc. Keeping this in view, it is very much helpful to study the effects of these parameters on the results obtained from percolation tests. In this paper, three different water samples with different physical and chemical properties were taken to study how these samples percolate in different soilmass. As expected, it was found that the rate of percolation decreases with increase in plasticity of soilmass and the fluid contamination. However, surprisingly, it was found that the percentage change in percolation with time remains almost constant. In present study, all the three water samples attained its steady state conditions after 8 and 40 minutes, respectively, for two different site conditions.
