Introduction
The rate at which we deplete and degrade our
fresh aquatic resources poses a great threat to our future life support system.
The rise in human population exploits more of natural resources and this is met
through the growth of industries specifically chemicals and petrochemicals,
urbanisation, deforestation and intensive agricultural practices. The industries
and urban sprawl discharge the waste into river. The deforestation process
itself aggravates the sedimentation transport into the streams. And the use of
chemicals in the crops for better production contaminates ground water through
percolation, and rivers and lakes through surface run-off. All these sporadic
degrading activities have lead to gradual deterioration in the quality of
surface and subsurface water. The loss of quality is causing health hazards and
death of human, livestock and death of aquatic lives, crop failure and loss of
aesthetics. Keeping in view the importance of good water quality, the Central
Pollution Control Board (CPCB), in 1976, initiated a series of integrated river
basin studies all over the country. CPCB in collaboration with the State
Pollution Control Boards (SPCB) established the Water Quality Monitoring (WQM)
network in the country. The CPCB has identified river stretches all over the
country, which have been polluted to the maximum extent. The Krishna river,
which is one such polluted rivers of the country, flows in the states of
Maharashtra, Karnataka and Andhra Pradesh. The present study is taken up for the
monitoring, identification and suggesting preliminary measures of water
pollution control in the Satara-Sangli stretch (stretch-I) of the Krishna basin
in Maharashtra with the help of Geographic Information System (GIS). The
stretch-I, also known as the country’s sugar-belt, has been identified by CPCB
and MPCB (Maharashtra Pollution Control Board) for the restoration of water
quality under the National River Action Plan (NRAP).
