Air
Quality Monitoring:
NAMP : National Air-quality
Monitoring Programme (NAMP), financed by the Central
Pollution Control Board aims to assess the ambient air
quality in the state. Under this programme at present
only one monitoring station has been established at
Bamunimaidam, Guwahati. A few numbers of monitoring
stations under this programme has been proposed to be
established very soon.
Air quality within industrial, commercial, residential
and silence zones are being monitored from time to time
within the state.
Water
Quality Monitoring:
All pollution control activities ultimately aim at maintenance
and restoration of the quality of the natural resources.
Hence knowledge
of the ambient quality of resources is a prerequisite
for planning and execution of pollution control management
strategies. The Board maintains a network for monitoring
of the ambient quality of the rich and varied water
resources of the state. There are 3 major schemes for
ambient water quality monitoring with the Board. They
are
MINARS
Programme
: Under Monitoring of Indian National Aquatic Resources
programme financed by the Central Pollution Control
Board this Board has already intensified its activities
for monitoring and analyzing the surface water quality
of certain selected rivers in the State. In this programme,
a total no of 10 (ten) monitoring stations in the Brahmaputra
River and its tributaries and 1 (one) in the Barak river
have been monitored by the Board regularly at monthly
intervals since the year 1987. The programme is still
continuing with increasing number of monitoring stations
from 11 to 29 (twenty nine) from August, 2002 which
includes 10 (ten) ground water samples collected from
selected parts of Assam.

Other
Monitoring :
The State of Assam is full of small lakes and tanks.
The water quality of these lakes and tanks are being
monitored time to time.
Also ground water monitoring of certain sensitive areas
of the State have been carried out by this Board in
time to time and such activities are still in progress
whenever it is found necessary. The district wise ground
water quality of some selected areas of the districts
have also been monitored under the project called Zoning
Atlas for Siting of Industries and is still going
on.
Also, effluent discharged by all major industries including
hazardous ones in the State are monitored in monthly
basis whereas other smaller industries are monitored
periodically or as and when necessary.
