The ground water quality status of waste disposal site in the eastern part of Kolkata - a case study
conference contribution
posted on 2018-02-12, 15:08 authored by P.B. Maity, T. Saha, P.B. Ghosh, D. ChatterjeeUntreated disposal of wastes, both solid and liquid
created by various human activities, causes contamination
of ground water through the processes of leaching, and
percolation through soil. The leachate containing soluble
nitrogen, phosphorus and sulfur compounds including
toxic metals, originated from the untreated waste
percolates through the soil and loads the ground water
with these compounds. Such loading may make the
ground water unsuitable for drinking purpose. The
problem is supposed to be more acute in areas like Dhapa
and Bantala situated at the eastern part of the city of
Kolkata. This area is not only the main disposal ground
of the Kolkata Municipal solid waste but also crisscrossed
with untreated city sewage carrying channels and
fisheries, fed with this sewage: A detail study of 16
parameters regarding quality of 23 water samples (from
8 villages) drawn from tube wells around the Dhapa
waste dumping ground, 12 water samples of tube wells
(6 from 3 villages and 6 from nearby 6 bheries) from
areas around fisheries of Bantala and 5 water samples of
tubewells from normal field of different parts of KMC
area have been assessed. The assessment results have
been compared with the values obtained from tube wells
of normal field of KlvIC area and for the same parameters
(available) of standard drinking water. The findings have
been presented in tabular form showing the departure
of the quality of water samples from those of the
standard drinking water in a qualitative way.
