Abstract
For this investigation, three different types of soil were chosen: very deep, coarse loamy, well-drained soil; deep, fine loamy, well-drained soil; and deep, coarse loamy, well-drained soil. Ten water samples were taken from the ring well, ponds, drains, and existing shallow tube wells (hand and mark tube wells) for each category of soil types. The minimal dada set, which include all variables, was chosen on the basis of the significant correlation discovered by correlation analysis. Very deep, coarse loamy, well-drained soil had the lowest water quality index (10.34), whereas very deep, fine loamy, well-drained soil had the highest (15.38).
