How can we identify pollution?
Sometimes pollution can be identified by sight and smell, such as seeing smoke rising from a smokestack. But most times pollutants can only be identified with physical tests. Identification of pollutants is the first step in reducing pollution in the environment to ensure cleaner air and water.

How is groundwater polluted?
Groundwater contamination occurs when man-made products such as gasoline, oil, road salts and chemicals get into the groundwater and cause it to become unsafe and unfit for human use. For example, pesticides and fertilizers can find their way into groundwater supplies over time.
Which one of these does not pollute water?

What are the signs of pollution in a river?
Signs of Pollution. If large amounts of fertiliser or farm waste drain into a river the concentration of nitrate and phosphate in the water increases considerably. Algae use these substances to grow and multiply rapidly turning the water green. This massive growth of algae, called eutrophication, leads to pollution.
Why are rivers more polluted than standing water?
Moving water dilutes and decomposes pollutants more rapidly than standing water, but many rivers and streams are significantly polluted all around the world. A primary reason for this is that all three major sources of pollution (industry, agriculture and domestic) are concentrated along the rivers.
How to stop pollution of rivers?
In fact, you can come up with your own campaign to spread the word. Persuade authorities to strictly implement pollution control regulations and people should be punished if they are found polluting the rivers or any other water body.
What happens when you put Dirty Water in a river?
Dirty water containing chemicals is put back in the river. Water used for cooling is warmer than the river itself. Raising the temperature of the water lowers the level of dissolved oxygen and upsets the balance of life in the water.
