Welcome for the Workshop on Hydro-
Meteorological Instrumentation
Real-Time Water Quality Monitoring System for
River Ganga
Suneel Dave Incharge NGRBA Cell
The Ganga
NGRBA Cell, CPCB Delhi 2
The Ganga - Important Locations
2nd September 2013 NGRBA Cell, CPCB Delhi 3
OBJECTIVES OF THE PROJECT
NGRBA Cell, CPCB Delhi 4
• To assess nature and extent of pollution. • To understand the environmental fate of
different pollutants. • To evaluate effectiveness of pollution control
measures in place. • To evaluate water quality trend. • To assess the fitness of water for different
uses
The Network – Locations
On Main Stem : o Upstream and downstream of major urban areas
o Downstream of Point sources from Industrial & Domestic
discharge
Major tributaries : Upstream of the confluence with the
Ganga
In major drains
At important mass bathing place
Upstream of intake well for drinking water
treatment plants
Downstream of wastewater treatment plants

The Network - Stations
NGRBA Cell, CPCB Delhi
Class I: Indicates the primary stations at selected locations of the Ganga main stem. These will act as impact or baseline stations for maximum parameters
Class II: Indicates the secondary stations at the remaining locations, on the main stem and at important tributaries for limited parameters
Class III : Indicates stations in major drains for selected parameters
