To conclude, we found that the effluents of the industrial areas are discharged partly untreated into streams, underground and ponds. They contain appreciable amounts of inorganic and organic chemical and the bye-products. The common effluent treatment plants in Bolaram and Patancheru let out that there are not sufficient treated effluents in Pamulavagu and Peddavagu also polluting Nakkavagu. The irrigation tanks are used for effluent settlement tanks and spill over joins Tamulavagu and Peddavagu. Dispersal of contamination by interactions between surface water and aquifer system is visible.
