The groundwater in the Varahi river basin in Udupi distirct and
Markandeya river basin in Belgaum district, both situated in
Karnataka state were evaluated for their physico-chemical
composition, radon and tritium content in addition to their
suitability for domestic and irrigation purposes. In comparison
with Varahi river basin, considerable area in the Markandeya river
basin are having high salinity hazards, TDS, hardness, alkalinity,
chloride, etc., and such zones require special care and alternative
salt tolerant cropping pattern. The groundwater data sets were
subjected to geochemical modelling to depict the equilibrium state
of various minerals species controlling geochemistry of water.
Majority of the analyzed groundwater in Varahi (93.34 %) and
Markandeya (68.75 %) river basins exhibited radioactive decay (1-8
T.U.) having a mixture of pre-modern (viz., old water) water with
modern (viz., new water) recharge. The annual effective dose due to
ingestion of water-borne radon were significantly lower than the
UNSCEAR and WHO recommended limit for members of the public at 1
mSv/year. Groundwater data sets were also subjected to multivariate
statistical analysis.
