Study on the Quality of Water in the Bhavani River

Abstract

With a view to create awareness among the public about the quality of
water in the Bhavani River, which is one of the important rivers of
Tamilnadu, this study has been undertaken. The samples of water have
been collected at various points along the course of the Bhavani river from
the Nilgiris to Bhavani Kuduthurai. The samples of water were collected
using standard procedural methods. The physiochemical analysis and biological
examinations were extensively carried out on each sample using
known standard methods. The results of these analyses point out the fact
that the Bhavani river water is being highly polluted by letting out industrial
effluents, industrial waste water, agricultural run off and sewage into the
stream. The presence of inorganic ions such as hexavalent chromium,
sulphate ions, etc., and biological waste has contributed to the pollution
of the river water. As a result water borne diseases have become common
in this area and the raw water cannot be used as such for industrial purposes.
The Bhavani river water should be treated properly and disinfected before
being supplied for industrial purposes and human consumption.
