I need help with this question

Dear student,
Different ways of water contamination are:
1) Waste from industries: Industries cause chemical contamination of water by releasing chemical like lead, arsenic that are toxic for us as well as the soil and plants. These cemicals get dissolved in water bodies and also lead to pollution of ground water.
2)Untreated sewage: When untreated sewage is released into the rivers, it contains many household waste and microorganisms that pollute water. This water contains many pathogens too.
​​​​​​3) Cremating the dead bodies near river banks.leads to pollution of water bodies too.
4)Pesticides and weedicides in agriculture can flow to water bodies and just contaminate it.
5)Plastic is blown in by the wind or washed in via storm drains and sewers.into the oceans or rivers which causes pollution of water.
