2 Report on Quality Survey and Monitoring of Nakkavagu Basin & Surrounding Borewells and Monitoring of Kazipally, Asanikunta & Kistareddypet Tanks in Medak District, Bhagavathi Ana Labs Ltd., Date not specified Identify point and non-point sources of pollution Developing water quality parameters data from December 2009 to March 2010 Estimate bacteriological pollution in stream and tank waters Socio-economic data in the catchment area Land use and land cover data Interpret groundwater and surface water data for drinking and irrigation standards. Observations on water usage in the village, for cultivation, drinking and for animals Organic Parameters – DO, COD, TOC, BOD, Phenols Nutrients – TKN, Nitrate, Ammoniacal Nitrogen, Total and Ortho Phosphates Heave metals Inorganic parameters Results indicate inflow and outflow of Asani Kunta Lake are grossly polluted. The reported salts concentration was very high. There was an increase in salts concentration at the outlet compare d to inlet values. This was attributed to evaporation in the lake. was slight reduction in COD and BOD values in outlet sample compare dto inlet sample. should advice Hetero Lab, SMS Lab, Divis Lab and Lee Pharma to avoid surface runoff along their boundary walls and avoid stagnation of water within their premises Cemented drains which are allowing seepage to be fixed Surface flow coming out of industries joining the cemented channels must be diverted or blocked to avoid flow generation in cemented drain channel 3 Remediation of Asani Kunta Lake, Identify and Lake Sample / Surface Summary of analysis of Asani Kunta Treatment of lake water with the Bollaram IDA, Medak District, non-point sources of (Drain) / Groundwater – Physico- Lake water samples inferred: following options March 2006 -Wilbur Smith pollution chemical, heavy metals, The pH values in the water samples Development of a temporary Associates Private Limited Develop water bacteriological, GC-MS, and zoo ranged from 7.2 to 8.2 treatment plant at Khazipally quality data for pre and phytoplankton study The TDS and COD values recorded Treatment of lake water in
and post monsoon Estimation of bacteriological pollution and bio indicators of groundwater quality surrounding the lake Study of sediment quality of the lake Study of influents to the lake and estimation of pollution load Survey of inflow and outflow quantities and lake water balance study Social economic data in the catchment area Land use and land cover data Develop best technology for lake restoration and Surface water (Drain) / Groundwater – Physico-chemical, heavy metals, bacteriological, GC- MS, and zoo and phytoplankton study Soil /Sediment / Groundwater - Physico-chemical, heavy metals, bacteriological were very high with maximum value of 9500 mg/l and 1100 mg/l respectively. The area showed an increasing trend in all parameters (TDS, Chlorides, COD, and BOD) from monsoon to post monsoon season. The pH values in the water samples ranged from 7.2 to 8.2 The TDS and COD values recorded were very high with maximum value of 9500 mg/l and 1100 mg/l respectively. The area showed an increasing trend in all parameters (TDS, Chlorides, COD, and BOD) from monsoon to post monsoon season. The high TDS, BOD and COD were found to be characteristic of pharmaceutical industries and hence were attributed to the mixing of industrial effluents. Lead was reported in excess of acceptable limits in both pre and post monsoon samples. Concentration of heavy metals such as copper, manganese, zinc etc. Summary of analysis of sludge samples inferred: Heavy metals were reported in significantly high concentration in sampling The presence of TKN indicated nitrate pollution in the water body Summary of analysis of soil samples existing CETPs Development of a CETP adjacent to Jillela Vagu on the upstream side of Khazipally Tank Desilting of accumulated bottom sediments Strengthening of the bunds and appropriate inflow and surplus flow arrangements Beautification of lake including development of recreation facilities post-
Organoleptic findings: Surface water Location Reference Number Area Observations Photographs A1 flowing out from SOM Phytopharma (India) Pvt. Ltd. Pale yellow water, very strong chemical odour. PID: 1,395 ppm.
Location Reference Number Area Observations Photographs A2 Surface storm water drain flowing along IDA Bollaram main road, opposite Huhta-Maki-PPL. Water was visibly pale yellow in colour with a strong chemical odour. PID: 11.7 ppm
Location Reference Number Area Observations Photographs A3 Residential settlement North of IDA Bollaram main Road where drain flows under the main road. Surface water drain adjacent to residential settlement in Bollaram area. The drain runs from the IDA Bollaram main road through the residential area and further flows into Asani Kunta Lake. PID: 260.3 ppm
Location Reference Number Area Observations Photographs A8 Drain flowing out of Asani Kunta Lake under the bund and the southern-most point of the lake. Lake was observed to be dark black in colour with strong sewage and chemical odour. PID: 362 ppm
