The present study is an in depth analysis of groundwater pollution along the
industrial zones of Lahore, Kasur and Kala Shah Kaku. A total of forty (40)
ground water samples were collected randomly from study area out of which
twenty(20) were taken from Lahore, ten (10) were gathered from Kasur while
ten(10) from Kala Shah Kaku. In order to evaluate the groundwater quality,
different physical parameters (pH, TDS and Electric Conductivity) chemical
(Calcium-magnesium, Sodium, Bicarbonates, Chloride) and metals (Cr, Cd, Zn,
Pb, Mg and Ni) were analyzed and were compared with the prescribed limits of
(WHO, 2011). The deduced results revealed that all the physio-chemical
parameters were within the prescribed range of WHO, except EC that exceeded
the permissible range of WHO. Based on mean values heavy metals in ground
water samples followed the declining concentration (Mn>
Zn>Cu>Cd>Cr>Pb>Ni). Manganese and Zinc were found to be in magnified
concentrations. The results demonstrated that effluents discharged from various
industries without treatment are a potential threat to underground water
contamination. Thus, it is recommended that waste water treatment plants should
be installed by these industries. Furthermore, strict government actions, effective
environmental laws and social awareness programs must be undertaken.
