Whaddup water pollution?

Have you ever thought about what kinds of pollutants are in your water? Water pollution is any chemical, physical or biological change in the quality of water that has a harmful effect on any living thing that drinks, uses, or lives in it. Their are different types of water pollution. For example: nutrient pollution means that there is too much nutrients and it creates weeds and algae. Oxygen depletion is when too much biodegradable material is added to water, the number of micro organisms increase and use up the available oxygen. Ground water pollution is when drinking water coming from aquafers are polluted. Surface water pollution is when oceans, rivers, or lakes become polluted. We detect water pollution by small samples of water can be analized in a lab to detect water pollution or they can find water pollution through organisms that live in purified water. One of the largest water pollution disasters has recently happened. It was the 2010 BP oil spill in the Gulf of Mexico.
