摘要：Coastal groundwater has always been circumspect with severe geochemical impacts which impartqualitative fluctuations from time to time. The Bay of Bengal coast of Srikakulam district in AndhraPradesh, India has witnessed many geomorphological changes in the recent times and there was asevere concern over the groundwater quality. A geochemical assessment was carried out for twoseasons along the coast to investigate the contributing factors for these qualitative deviations. Twentynine groundwater samples of bore and open wells of pre and post monsoon seasons were analysedfor various physico-chemical parameters. The chemical, geological and geophysical interpretations ofthe data revealed mechanisms controlling the origin of the chemical ions in the groundwater. The flowpatterns, geochemical facies and zones, intrusion zones along with the present status were examinedduring the assessment. The geochemical factors imparting the qualitative changes of the groundwaterwere quantified.
