Abstract:
Groundwater quality in southern province is varying considerably in between Galle, Matara
and Hambantota. Hambantota district has recorded as Chronic Kidney Disease in unknown etiology
(CKDu) prevailing districts. Some researchers suggested that it has a relationship with contaminated
ground water. Fluoride, Hardness, Heavy metals and other typical inorganic water quality parameters
have been analysed in the samples collected from 303 stations. The parametric values of F\ Ct, SO42'
, Na+, NH4+, Mg2*, Ca2+, Hardness and Mn in Hambantota are higher than the recommended maximum
level allowed according to the Sri Lankan Standard (SLS) for drinking water while NHS, Al and Mn are
recorded in Matara. But in Galle district Pb shows high concentration by giving a clue towards the
vehicle gas emission. Principal Component Analysis has identified 7 components in Galle which
explains 75.4% of total variance. In Matara and Hambantota, 6 components explain 75% and 76% of
the total variance respectively.
