Fig. 1 a Sampling locations at river bank filtration site. b Inside view of the production well
water samples were tested in the laboratory. In addition, soil samples taken from the
river bed at a depth of 1 m were subjected to sieve analysis for gradation of soil.
4 Sieve Analysis of Soil Collected from River Bed
IS code was used for grain size analysis of the soil sample [7]. The soil sample
was collected at a depth of 1 m from the river bed. Dry sieve analysis was done at
laboratory, and the percentage finer and particle size graph was plotted (Fig. 2).
