Which of the following is a source of water pollution? a. sewage b. oil spills c. fertilizers d. all of the above

The correct answer is - d. all of the above.

The sewage is a water pollutant all around the world where there's human settlements. It goes directly into the nearby streams, rivers, lakes, seas, and contributes to their pollution.

The oil spills, even though are not very common, when they do, they are devastating and are damaging the water to a degree where it can not be used for anything, and it also has long term effects.

The fertilizers from the agriculture contribute to the pollution of the water in a way of eutrophication, which means that they significantly rise the nutrition in the water. This occurs when the fertilizers, through washing through the soil caused by rainfall, managed to reach to the underground waters, and since most of them are connected to the surface waters, they pollute them as well.
