A Study on Effect of the Treated Effluent on Groundwater in and Around STP, Shivanagara, Davanagere

The adverse activities implemented at the municipal sewage treatment plant and the anthropogenic activities of human beings are adversely affecting top layer soil and groundwater quality. This paper discusses about the effect of treated effluent on groundwater quality around STP, Shivanagara, Davangere. The analyzed samples were collected at 17 different locations and carried out to analysis of the physico-chemical properties later the obtained results were discussed by comparing it with the permissible limit of water standards published by the Bureau of Indian Standards and provides the reason for effect of effluent percolation into groundwater. However, the WQI analysis has revealed that about the 99% of the samples are classified as good and 1% of the water was poor and indicates that treatment processes implemented at the STP is insufficient in an order to avoid the contamination of the groundwater and advises that the sewage treatment plant facility must enhance the treatment of effluent before discharging it to the open field, canal, storage tanks.
