Quality of Ground Water in the Coastal Aquifer Near Visakhapatnam, India

Abstract

ABSTRACT A study of the quality of ground water from 250 open wells in the coastal aquifer of Kaniti‐Paravada near Visakhapatnam, India brings out the fact that the occurrence of highly brackish waters in certain localized pockets is due to the hydrogeological processes going on in the area and not due to the influence of the sea. The phenomenon is verified by determining standard ratios of tracing sea‐water contamination like Ca/Mg, Cl/HCo 3 ’and TA/TH. Conductivity and sodium adsorption ratio are also determined for finding out the alkali hazard, to supplement the observations.
