This document discusses the real-time water quality monitoring system for the River Ganga. The objectives are to assess pollution levels, understand how pollutants behave, evaluate effectiveness of controls, and track water quality trends. The network includes over 100 monitoring stations along the main stem and tributaries of the Ganga in 4 states. Stations continuously measure 19 parameters including ammonia, BOD, pH and more. Data is collected, validated, processed and disseminated online for public access. The workshop will discuss experiences with similar projects, available technologies, implementation models and options for CPCB.

•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

5. The Network – Locations
On Main Stem :
o Upstream and downstream of major urban areas
oDownstream 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
