SUJALA can be used cost-effectively to bring down the pollution index from a high value(even 100) to 0.

One can notice from the above table that land, water and air have varying ability to remediate pollution, in a decending order. It is sad that we use air for most discharges, followed by water.

Incineration should never be allowed because it shifts the pollutants into the air.
