Importance of groundwater use for drinking, cultivation and industrial purposes is increasing at present in rural and urban areas of the world. So prevention of subsurface water’s pollution become necessary even in coastal regions as its occurrence in small amounts. Proper management and maintenance of quality of subsurface water is needed for safety of health aspects of all the creatures on the earth surface and to improve the yield of agricultural crops. So quality study is done in Sangupalemkoduru region of coastal part of Andhra Pradesh state of India. Subsurface water occurs in shallow depths in the study area. Subsurface water samples are tested for various chemical constituents present in that water. Most values of these constituents are not within safe limits of potable water. Values of Electrical conductivity, Sodium Absorption Ratio, Residual Sodium Carbonate and Percent Sodium methods indicate that this water is highly polluted and not suitable for cultivation purpose as per Wilcox classification. Thus some of hydro chemical processes which govern its quality in this region are observed. Proper measures are proposed to prevent subsurface water pollution in this area.
