WATER QUALITY OF TOLLY’S NULLAH

Project On: – WATER QUALITY  OF  TOLLY’S NULLAH
( FROM  KHIDERPORE  TO  KUDGHAT)
DURING POST-MONSOON

The project was undertaken by the students of  batch No. 28 of Environmental Analyst Course of the Institute under the able guidance of their faculty Mr. Debashish Chatterjee and Ms. Sruti Chatterjee.

It was undertaken during the last week of December 2010. The project was mainly intended towards finding out the water quality of Tolly’s Nullah as compared to the quality of Ganga water both during high tide and low tide. It was based on a small sample size study of 7. The sample locations were selected on the basis of their scenario and activities. However the standard methodology was followed during the process and the outcomes of the project are based on the physical and chemical parameters of the samples.

Water Quality Monitoring of 8 Urban Water Bodies in Kolkata

This is an ongoing research project at SEI. The water bodies being covered are those in or around Kolkata, India. They are –

  1. Subhas Sarovar
  2. Rabindra Sarovar
  3. Manohar Das Talab
  4. Pond at Eden Gardens
  5. Ponds at Victoria Memorial
  6. Pond at College Square
  7. Pond at Santosh Mitra Square
  8. Pond at Nature Park (Budge Budge)

Physical, chemical and biological parameters are being tested to determine the following :-

  • Water Quality
  • Level of Degradation
  • Remedial Measures for Sustenance

Some of the parameters that are being tested include pH, Dissolved Oxygen (DO), Chemical Oxygen Demand (COD), Total Hardness, Salinity, Nitrate-Nitrogen, Nitrite Nitrogen, Total Alkinity, Phosphate-phosphorous, Total Iron, Sulphate, Biological Oxygen Demand, Coliform Bacteria.

A scientific Sampling method is followed.

The Water Quality Monitoring Report for Subhas Sarovar near Beliaghata, Kolkata is ready. To ask for a copy, write to SEI or leave a comment.
