Abstract-
Hisar is one of the fastest industrializing cities of Haryana. Major industries include stainless steel strips, cotton yarn, sewing thread, medicines, gaur gums, m.s pipes and alloy steel ingots. Solid waste from industrial units is dumped near the factories which on reaction with infiltered rainwater reaches the groundwater level. Untreated waste from septic tanks and toxic chemicals from underground storage tanks and leaky landfills also contaminate groundwater. The present study monitors the effect of industrial effluents on the quality of groundwater. Samples were collected from auto factory, pop factory, steel industry, pipeline industry and paper con industry located in the Industrial area and physiochemical characteristics of groundwater samples were studied. Results obtained were compared with the standards prescribed by WHO and BIS. The results show that most of the physiochemical parameters were found within the permissible limits suggesting that the hand pump water is quite suitable for domestic purposes by workers. However, the values of chloride, total organic carbon (TOC) and total solids (TS) were found beyond the prescribed limits suggesting that the hand pump water is not portable for drinking purposes. Study also revealed that Steel Industry and Auto factories show maximum values for most of the parameters indicating that these have maximum impact on the quality of groundwater.
