Make a table of water pollutants and their effects.

Explanation:
Types of water pollution
There are many types of water pollution because water comes from many sources. Here are a few types of water pollution:
1. Nutrients Pollution
Some wastewater, fertilizers and sewage contain high levels of nutrients. If they end up in water bodies, they encourage algae and weed growth in the water. This will make the water undrinkable, and even clog filters. Too much algae will also use up all the oxygen in the water, and other water organisms in the water will die out of oxygen starvation.
2. Surface water pollution
Surface water includes natural water found on the earth's surface, like rivers, lakes, lagoons and oceans. Hazardous substances coming into contact with this surface water, dissolving or mixing physically with the water can be called surface water pollution.
3. Oxygen Depleting
Water bodies have micro-organisms. These include aerobic and anaerobic organisms. When too much biodegradable matter (things that easily decay) end up in water, it encourages more microorganism growth, and they use up more oxygen in the water. If oxygen is depleted, aerobic organisms die, and anaerobic organisms grow more to produce harmful toxins such as ammonia and sulfides.

When humans apply pesticides and chemicals to soils, they are washed deep into the ground by rainwater. This gets to underground water, causing pollution underground.
This means when we dig wells and bore holes to get water from underground, it needs to be checked for ground water pollution.
5. Microbiological
In many communities in the world, people drink untreated water (straight from a river or stream). Sometimes there is natural pollution caused by microorganisms like viruses, bacteria and protozoa. This natural pollution can cause fishes and other water life to die. They can also cause serious illness to humans who drink from such waters.
6. Suspended Matter
Some pollutants (substances, particles and chemicals) do not easily dissolve in water. This kind of material is called particulate matter. Some suspended pollutants later settle under the water body. This can harm and even kill aquatic organisms that live at the bottom of water bodies.
7. Chemical Water Pollution
Many industries and farmers work with chemicals that end up in water. This is common with Point-source Pollution. These include chemicals that are used to control weeds, insects and pests. Metals and solvents from industries can pollute water bodies. These are poisonous to many forms of aquatic life and may slow their development, make them infertile and kill them.
8. Oil Spillage
Oil spills usually have only a localized effect on wildlife but can spread for miles. The oil can cause the death to many fish and get stuck to the feathers of seabirds causing them to lose their ability to fly.
marine oil pollution
Do you remember the BP Oil spill in 2010? (Read about it here) Over 1,000 animals (birds, turtles, mammals) were reported dead, including many already on the endangered species list. Of the animals affected by the spill, only about 6% have been reported cleaned, but many biologists and other scientists predict they will die too from the stress caused by the pollution.
A table of water pollutants and their effects are :
•Water pollutants include contamination due to domestic wastes, insecticides
and herbicides, food processing waste, pollutants from livestock operations, heavy metals, chemical waste, and others.
•Industrial waste:
Industries produce a huge amount of waste which contains toxic chemicals and pollutants which can cause air pollution and damage to us and our environment.
•Sewage and wastewater:
The sewage and wastewater that is produced by each household is chemically treated and released into the sea with fresh water.
•Marine dumping:
The garbage produced by each household in the form of paper, aluminum, rubber, glass, plastic, food is collected and deposited into the sea.
