Buddha Nallah is a natural water stream. It passes through Ludhiana,
which is industrial town of Punjab. Effluents from industries and domestic area
joins stream and cause pollution. Pollution in stream leads to ground water
pollution of nearby region. Study was conducted to evaluate water quality index
(WQI) of ground water in region around Buddha Nallah in Punjab in districts
Rupnagar and Ludhiana, India. Water quality index was determined by taking
ground water samples from different sites during four different months over
span of one year and analyzing the samples for various physico-chemical
parameters. For evaluating WQI, eleven water quality features were studied; pH,
total hardness, total dissolved solids, electric conductivity, calcium,
magnesium, sodium, sulphate, phosphate, chloride and alkalinity. Results for
WQI of samples studied varies from 49.83 to 224.96. Results clearly shows that
in industrial town Ludhiana, ground water is polluted. WQI results were further
used to predicting ground water quality of area studied. - See more at:
