Water is Precious and scarce
Resource
• India is one of the wettest country in the world,
but rainfall is highly uneven with time and space
(with extremely low in Rajasthan and high in
North-East)
• On an average there are only 40 rainy days (100
hours)
• Out of 4000 BCM rainfall received, about 600
BCM is put to use so far.
• Water resources are over-exploited resulting in
major WQ problems

NATIONAL WATER QUALITY MONITORING PROGRAMME
•
Water quality monitoring in India started in 1978 under GEMS
Programme.
•
National programme of Monitoring of Indian National Aquatic Resources
started in 1984 with a total of 120 stations in 10 River Basins.
•
Present network comprising of 870 stations extended to 26 states & 5
Union Territories.
•
Monitoring done or Quarterly/Monthly/Half Yearly basis.
•
Monitoring network covers 189 Rivers, 53 Lakes, 4 Tanks, 2 Ponds, 3
Creeks, 3 Canals, 9 Drains and 218 wells.
•
Water samples are analysed for 9 Core Parameters (pH, Temperature,
Conductivity, DO, BOD, Nitrite, Nitrate, Total Coliform and Faecal
Coliform) for all monitoring. 19 General Parameters, 9 Toxic Metals and
15 Pesticides are also analysed once in a year.
•
Frequency of analysis for General Parameters reduced to once in a year
in view of resources and to add more stations in non-represented waterbodies. Frequency and Parameters does not match the guidelines of
GEMS. Base-line, Trend and Impact stations are maintained as per the
guidelines of GEMS.

Objective of Water Quality Monitoring
For rational planning of pollution control strategies and their
prioritisation;
To assess nature and extent of pollution control needed in different
water bodies or their part;
To evaluate effectiveness of pollution control measures already in
existence;
To evaluate water quality trend over a period of time;
To assess assimilative capacity of a water body thereby reducing cost
on pollution control;
To understand the environmental fate of different pollutants.
To assess the fitness of water for different uses.
CRITERIA FOR SELECTION OF MONITORING STATIONS
River/Stream
•
Water intake point - community water supply.
•
Large/medium polluting industries or cluster of SSI.
•

•
D/S of large irrigated areas.
•

•
D/S of big cities.
•
U/S and D/S of confluence of rivers.
•
Inter-state boundaries.

Outcome of National Monitoring Programme







Every year a compendium of water quality statistics is published and
circulated to various scientific institutes and processed data is put on the web
site for easy access.
Basin sub basin Inventory of water pollution is prepared and published for all
the major river basins in the country.
Water quality atlas is prepared to assess the fitness of river water for desired
uses in the country.
Water quality data is used for Identification of Polluted Water Bodies based on
violation of desired water quality criteria for designated uses.
Water quality data formed the basis for Formulation of River Action Plan and
Identification of Pollution Sources in 157 cities for interception and diversion
of municipal wastewater and stricter surveillance of industrial sources.
Water quality data is used for Query Response i.e. to reply Parliament
Questions, VIP reference, Public Queries, Public Interest Litigation filed in
Supreme Court and Various High Courts and to fulfill the requirement of Non
Governmental Organisation, Students, and Researchers.
Providing data to GEMS Programme on Water on annual basis for 72 stations
for global data base.
Constraints in Maintaining the Network
 Sustainability of infrastructure and maintenance of
instruments and equipments.
 Financial as well as Manpower resources are inadequate
and reducing due to policy shift.
 Travel to long distances for monitoring and preservation of
samples in warm weather conditions adversely affect the
results.
 Analysis results needs in-depth validation and repeated
interaction with laboratories.
 Improper reporting of units, variation in analysis methods
and quality control of chemicals are cause of concern.
 Lack of training for laboratory and field staff.
 Lack of software to analyse the data for trend analyses and
data validation.
Limitations of Monitoring Programme
 Problems in data validation due to fluctuation in water
quality.
 Flow in many rivers dwindles due to short period of
monsoon.
 Environmental flows are not maintained, hence only urban
wastewater flows in the rivers after major abstraction
points.
 Removal of outliers during validation of data may devoid
valuable information related to flushing of Industrial
effluents responsible for episodal pollution and fish kill.
 Need of software for processing, validation/trend analyses
and format data storage.
 Priorities for water quality management varies widely from
developed countries to developing countries.

IDENTIFICATION OF POLLUTED
WATER BODIES
• CPCB identified 10 polluted stretches for
prioritising pollution control efforts in 1988-89.
• The Number of Stretches increased to 37 during
1992-93.
• The list is now revised to 86 polluted stretches.
• The concerned State Pollution Control Boards
were asked to take adequate measures to restore
the desired level.
RIVER ACTION PLAN
• CPCB identified polluted water bodies, which leads to
formulation of action plan for restoration of the water
body.
• Based on CPCB’s Recommendations, Ganga Action Plan
was launched in 1986 to restore the WQ of the Ganga by
interception, diversion and treatment of wastewater from
27 cities/towns located along the river.
• Based on the experience gained during implementation of
the Ganga Action Plan, Govt of India extends river
cleaning programme to other rivers and lakes.
