Concept:The Ganga Action Plan is a government programme focused on reducing pollution in the Ganga River.
Its main goal is to improve the river's water quality by treating waste and controlling pollutants.
Explanation:The Ganga Action Plan was launched in 1985 by Prime Minister Rajiv Gandhi.
The river receives huge amounts of untreated sewage, garbage, and industrial waste daily.
This pollution harms aquatic life and makes the water unsafe for human use.
The plan aims to intercept, divert, and treat domestic sewage and toxic industrial chemicals.
It also targets non-point pollution from farming, bathing, and disposal of bodies.
New treatment technologies like Up-flow Anaerobic Sludge Blanket (UASB) are used.
Soft-shelled turtles are also deployed to help clean the river naturally.
The overall objective is to restore the water quality and make the river pollution-free.
