ESSAY: Causes Of Water Pollution with FREE PDF

Be it large or small, the Earth is home to many water bodies. Which we can see either while we walk, jog or drive around. Be it a lake, a river, an ocean, a pond etc. Since ages we have been polluting and destroying these water bodies for our comfort and luxuries and creating disasters and hassles for tomorrow generations too. On one hand, we are using the pure water from water bodies by extracting it directly through bore samplings. Or by creating hydro electric projects on them without giving any thoughts to the negative impact it will cause to the water quality of the already exhausted and polluted.

Causes Of Water Pollution

It’s important to know the causes of water pollution so we can take steps to reduce and eliminate harm. Some of them are:

(i) Sewage or wastewater: Sewage and wastewater are the main sources of water pollution. Sewage contains contaminants which come from households, factories, or agricultural land. Sewage can also pose health hazards to humans.

(ii) Dumping: A lot of water bodies get polluted by dumping of waste into them. This dump contains everything from plastic, aluminum to glass, Styrofoam, etc. And since all the waste takes different time to degrade in the water, they tend to harm the aquatic life until it is degraded.

(iii) Oil pollution: There are several ways in which oil gets spilled into the water bodies. One common way is when tankers carrying huge amounts of crude oil get wrecked. This results in thick sludge floating on the surface of the water bodies.

(iv) Acid rain: Acid rain refers to the acidic precipitation that occurs daily all over the globe. Such acidic rains are caused due to acidic particles present in the contaminated air. These Airborne particles of acid come from substances like sulfate of sulfur, nitrate of nitrogen and dioxide of nitrogen. These particles in the atmosphere get mixed with water vapor and result in acid rains and polluted the water.

(v) Industrial waste: Industrial waste is one of the most common sources of water pollution. It may contain toxic metals like mercury, lead, cadmium and chromium, as well as harmful chemicals such as polychlorinated biphenyls (PCBs), asbestos and petrochemicals.
