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
