What are things that can pollute your water?

Answer 1

Spill oil in it!

It can be polluted by factory wastes

First there are factory wastes which contain harmful or radioactive substances that get mixed up with water and spread diseases to fishes and use up oxygen in water which then suffocates the marine life. If these poisoned fishes get eaten by humans they might die. Then there are fertilizers and pesticides which are sprayed over plants and washed away by rains or floods to water bodies. They then use up oxygen as well as poison aquatic life. Household sewage contains harmful bacteria and that poisons and suffocates marine life. Sometimes this cases algae to grow over water in large quantity which uses up dissolved oxygen. Some fishes get tangled up in packaging's and some swallow Styrofoam which makes them feel full and stop them from feeding properly. Fish farms also pollute water because the fish that are kept in chemicalized pens have the water washed into water bodies and they pollute water. Oil spills often occur and they coat the water with oil preventing oxygen inside and blocking sunlight. Animal farms are also responsible for throwing the animal waste into sewers directly.

Acid rain, oil spillages, rubbish deposition, water-bourne diseases and radiation.

Bacteria, dust, trash, garbage are all things that contaminate water.
