Cooum is one of the degraded sub basins in Tamil Nadu. Surface water, groundwater in and around the basin is polluted by factors such as industries and domestic waste etc. This paper highlights the importance of sewage inflow through Cooum inlets and assess quality of the surface water and groundwater influenced by the discharges in Cooum basin. Sewage inflow was highest in Elephant Gate Bridge (3039 Cum/day) and Annai Kasthuriba Nagar (2651 Cum/day). Surface water results exhibited higher pH, BOD, COD, chloride and zinc content. Groundwater quality of the study area has a higher pH of alkaline in nature and total dissolved solids in the range of 859-1611 mg/L. Sodium concentration was much higher than permissible limits (110-357 mg/L), and sulphate concentration was about 672 mg/L in Avadi region. Investigation was taken up for groundwater quality assessment through Water Quality Index, for drinking purpose, of open well in Cooum basin. Groundwater variables such as electrical conductivity values vary from 1760 to 2540 μS/cm. Analysis was taken for the parameters such as pH, electrical conductivity, total dissolved solids (TDS), calcium, magnesium, sodium, potassium, bicarbonates, chlorides, sulphates and nitrates. WQI ranges from 221 (very poor water) for Govindampadi to 321 for Avadi (unsuitable for drinking).

Abstract


Cooum is one of the degraded sub basins in Tamil Nadu. Surface water, groundwater in and around the basin is polluted by factors such as industries and domestic waste etc. This paper highlights the importance of sewage inflow through Cooum inlets and assess quality of the surface water and groundwater influenced by the discharges in Cooum basin. Sewage inflow was highest in Elephant Gate Bridge (3039 Cum/day) and Annai Kasthuriba Nagar (2651 Cum/day). Surface water results exhibited higher pH, BOD, COD, chloride and zinc content. Groundwater quality of the study area has a higher pH of alkaline in nature and total dissolved solids in the range of 859-1611 mg/L. Sodium concentration was much higher than permissible limits (110-357 mg/L), and sulphate concentration was about 672 mg/L in Avadi region. Investigation was taken up for groundwater quality assessment through Water Quality Index, for drinking purpose, of open well in Cooum basin. Groundwater variables such as electrical conductivity values vary from 1760 to 2540 μS/cm. Analysis was taken for the parameters such as pH, electrical conductivity, total dissolved solids (TDS), calcium, magnesium, sodium, potassium, bicarbonates, chlorides, sulphates and nitrates. WQI ranges from 221 (very poor water) for Govindampadi to 321 for Avadi (unsuitable for drinking).
