Malwa region of Punjab state, India has become the center of water borne diseases due to excessive
use of pesticides, chemical fertilizers, heavy metals, industrial toxins that cause toxicity in water. The
main contamination in ground water is by physico-chemical parameters and heavy metals i.e. pH,
total dissolved solids, total alkalinity, total hardness, calcium, chlorides, fluorides, arsenic and lead.
The contamination of ground water with heavy metals causes health hazards to humans and animals.
Due to lack of adequate facilities and resources for the management and handling of waste, the ground
water contamination has been increased. In the present study, assessment of ground water quality was
carried out in the villages of Ferozepur district of Punjab state, India. With main emphasis on analyzing
the groundwater parameters of Ferozepur district which are responsible for health hazard to humans
and animals. Various groundwater samples were collected randomly from the villages of Ferozepur
district and analyzed for pH, total dissolved solids, total alkalinity, total hardness, calcium, chlorides,
fluorides, heavy metals (arsenic and lead) using standard procedures. The concentrations of calcium,
chlorides, fluorides and pH were within the permissible limits, whereas, alkalinity and total hardness
were observed beyond permissible limits in most of the water samples. Even among majority of the
samples taken, the concentration of arsenic and lead was found within the permissible limits. Results
showed that the ground water samples collected from depth ranging from 100 to 360 ft, recorded
values within permissible limits for drinking purpose as prescribed by WHO. Further, ANOVA has
been applied on analysis results to study the effect of pH on fluoride and chloride, depth on fluoride
and chloride and depth on arsenic and lead. Also, to adjudge the overall quality of water in Ferozepur
district, the water quality index (WQI) has been calculated on the basis of large number of
physico-chemical characteristics of water. The water quality index of ground water in Ferozepur district
has been calculated to be 107. The value is close to 100 so the quality of ground water in Ferozepur
district can be categorized under 'Good Quality' water.
