Abstract
This paper presents groundwater quality of Ambattur industrial area in Chennai City. Ten different locations were
selected for the study and compared. The parameters studied were pH, total alkalinity, total hardness, turbidity,
chloride, sulphate, fluoride, total dissolved solids and conductivity. From overall analysis, it was observed that there
was a slight fluctuation in the physico-chemical parameters among the water samples studied. Comparison of the
physico-chemical parameters of the water sample with WHO and ICMR limits showed that the groundwater is highly
contaminated and account for health hazards for human use.
