Answer 2

Answer:

There are a number of ways of identifying pollution. These include finding symptoms of damage to aquatic plants and animals (such as dead fish), finding chemicals in the water, comparing the previous history of the quality of water with the present quality, and getting complaints from water users.

For example, water samples from several different points upstream and downstream will need to be analysed to locate precisely where the problem originated
