Abstract

Goa occupies a narrow strip of western India coast line, fifteen Km long and sixty-five Km wide with a total
area of 3701 Km Sq. It lies between latitude N14º15ˈ and N15º48ˈ and longitude 74º40ˈ1ˈˈE and 73º40ˈ33ˈˈE.
Goa is dominantly covered by the rocks of Dharwar supergroup of Archean Proterozoic age except for a
narrow strip along the North-East corner occupied by the Deccan traps of upper Cretaceous to lower Eocene
age. Forty five representative samples were collected from Bore well and open well and were subjected to
chemical analysis to study the cations, anions and non-ionic parameters to decipher the chemical characters of
Bicholim area. From the Hydro chemical investigation the sample are acidic as well as basic in nature, they
have less TDS and low Electrical conductivity, as the water samples are fresh waters. Majority of the water
samples are within the permissible limit for different applications. The Pipers classifications indicates 91% of
the sample show carbonate hardness exceeds 50%, 2% of the samples shows non-carbonate alkali exceeds 50%
and 6% show carbonate alkalis exceeds 50%. The details of the investigation are dealt in the paper.
