This case study paper reviews ground water pollution to agriculture soil due to the natural shale value of heavy metals in
soil system. Thus, untreated industrial effluents can cause an environmental threat to ground water resources and affects soil
quality and agricultural plant productivity. To achieve unpolluted wastewater discharge into receiving water bodies, careful
planning, adequate and suitable treatment, regular monitoring and appropriate legislations are necessary. Parameters that may be
tested include temperature, pH, turbidity, salinity, nitrates, TDS, Cations, Anions and phosphates. Rapid Increase in population,
Construction of residential complexes and wide spread Industrialization in Namakkal Town has drastically reduced the land area
for wastewater disposal Groundwater pollution occurs when untreated or partially treated Industrial waste water are discharged
on to the land or used for Irrigation, enabling the waste to migrate down the water table through soil. Twenty (20) sampling
locations were selected in nearer to the sources of contamination. The water and soil samples were collected from the selected
sampling points. The samples were analyzed for major chemical water quality parameters like pH, EC, Ca, Mg, Cl, SO4, Na, CO3
and HCO3.The soil samples were analyzed pH, EC, Cl, SO4, PO4 and NO4.bThe groundwater quality based on Sodium percent,
Sodium Absorption Ratio and Residual Sodium Carbonate will help to identify the suitability of water for irrigation purpose.
Rapid industrialization and use of chemical fertilizers and pesticides in agriculture are causing deterioration of water quality and
depletion of aquatic biota. This aim of the present study was to assess the quality of the ground water and the impacts of the
Municipal wastewater. This study will be very helpful to under-stand the impact/evaluation of the rate of dumping of effluent
water in ground water and impact on the quality of water in terms of irrigation and the impacts onto the environment.
