| Water
quality mapping of rivers in India is a measure to identify the reaches where
the gap between the desired and the existing water quality is significant, to
warrant pollution control measures. However, the existing management system is
not enough to link the desired quality level to the water quality level for various
designated-best-use. In western countries, such as Federal Republic of Germany,
the maps based on bio-monitoring have proved as a powerful tool for preparation
of action plan for control of pollution and for improvement of water quality of
rivers. The Central Pollution Control Board has taken up a project to utilize
the bio-monitoring data of rivers to evolve a bio-map of entire stretches of river
basins in India. In this issue of PARIVESH Newsletter the methodology
of biological classification of various stretches of river basins has been presented.
The information for the issue has been collected, compiled and collated by Dr.(Mrs.)
Pratima Akolkar, Sh. G. K. Ahuja, Dr. C. S. Sharma and Ms. Chetna Kohli under
supervision of Dr. S. D. Makhijani. |
