The summary of the identified hazardous & municipal solid waste sites for implementation under this project in two States of Andhra Pradesh and West Bengal is as under:
Noor Mohammad Kunta (Hazardous Waste Site) in Andhra Pradesh:
Noor Mohammad Kunta is a small surface water body (13.96 ha-actual, 7.95 ha as per EPTRI Report, 1997) in the midst of industrial area and adjoining NG Ranga Agricultural University Rajendranagar Municipality of Hyderabad with its catchment area of 175 ha. consisting of industrial, commercial, residential and agricultural areas, plus two feeder channels. It is severely contaminated with pollution from Katedan Industrial Estate and nearby residential pockets.
Noor Mohammed Kunta
Most of the pollution comes from textile production - particularly the dyes used in production and the Kunta site is notoriously known as the Pink Pond due to its bright pink tint. The study report reveals high concentration of heavy metals in the lake including Lead, Copper, Chromium, Zinc, Iron, Nickel, Maganese etc. Bacteriological analysis indicates that the Total Coliform count (MPN) is much higher (174 to 640 MPN/100ml) than the permissible limits of drinking water.
The presence of high levels of non-biodegradable elements can be attributed to high levels of chemical pollutants from the industrial effluents. Contaminate soil, surface and ground water under to Kunta poses severe risks to residents and cattles.
Hooghly Site (a cluster of Seven Hazardous Waste Site near Kolkata) in West Bengal:
Ashalata Brickfield (HW-1); Minu Computer Weighbridge access road (HW-2); Shivang Trexim & Sree Balaji Veneers Access Road (HW-3); Pashupati Seong (HW-4); Access road south of Sarkar Bridge (HW-5); Zenith Timbers access road (HW-6); and Near Shivam Gases - Chakundi (HW-7) are the seven dumpsites in Hooghly district about 40 KM North of Kolkata spread over 15 km long stretch along Kolkata-Delhi Road containing highly toxic chromium have contaminated the soil and surface water media. The waste dumped is generated as sludge from manufacturing of Basic Chromium Sulphate (BCS) and its source is likely to be the three basic chromium sulphate manufacturers in the area namely, Indotan Chemicals, Bajaj Chemicals and Alhrome.
Shivang Trexim Site
The study report highlights the monitoring analysis carries out by National Productivity Council to assess the extent and severity of contamination in the region in the year 2006. The concentration of chromium in soil is found to be quite significant. Surface water in the surrounding pond adjacent to these sites was also observed to be contaminated.
The waste present at the sites contains leachable constituents as identified in the Toxicity Characteristics Leaching Procedure (TCLP) tests and continue to contaminate the surface water and long term potential to contaminate ground water too. The risk to the community and ecology is evident and thus, the study recommends to develop a remediation plan with an objective of containing the contamination and providing conditions conducive for natural attenuation.
Municipal Solid Waste Site in Kadapa Town of Andhra Pradesh:
This site is located in Ukkayya Palli 3 km away from Kadapa town at Patha Kadapa where 10.85 acres of land is used for open dumping since 1988. The distant between human habitation and the dump yard is less than half a kilometer. The site is basically municipal solid waste dump site and is ready for taking up for rehabilitation and improvement works. The estimated volume of waste disposed is around 1,11,000 tonnes and the age of the fill is around 20 years

Municipal Solid Waste Site - Dhapa in Kolkata of West Bengal:
The site is 10 kilometers away from the city adjacent East Kolkata Wetlands, only Ramsar site in West Bengal. The site is extended in East and West directions covering an area of 70 acres divided into two parts i.e. 23 acres in Western side used for dumping by Kolkata Municipal Corporation and the remaining 47 acres on Eastern side as land filling by the Private Sector. At present the layers of the waste disposed reached the height of 17 meters thickness.
The two sites are open dumps produce leachate which may potentially contaminate the northern side of the dump area posing risk to aquatic flora and fauna in the near by streams and adjoining population. The study proposes remediation of the Western part of the dump site i.e. 23 acres initially, which has already been filled-up for the last 10 years. The estimated volume of waste dumped is around 14,40,000 tonnes.
