Water is the most significant asset for endurance on a planet. It is the embodiment of life on our planet – Earth. However, if you ever get a chance to observe a stream or lake, it is apparent to you that we are confronting an intense issue of Water Pollution. Let us teach ourselves about water and water contamination. 66% of the Earth’s surface is water, 76 percent of your body comprises water.
What is water pollution?
Various definitions of water pollution are stated here.
Water pollution usually means defilement of water bodies (seas, oceans, lakes, streams, springs, and groundwater) triggered by human activities. Water pollution is any degradation, in the physical, synthetic, or natural properties of water that adversely affect the living beings. Potable Water is safe for drinking.
One can characterize Water Pollution as the degradation of the physical, chemical, and biological characteristics of water by natural and anthropogenic activities to such an extent that it is harmful to humans, plants, and animal communities. According to the United States Public Health Services, water contamination implies any toxic material in the water that degrades the quality to constitute a danger or impairs its usefulness.
What is contaminated water?
Less than 3% of the Earth’s water comes from freshwater sources and is practically the only source of all drinking water. Freshwater pollution or Freshwater contamination is the contamination of streams, rivers, lakes, and groundwater. Contaminated water affects the ecosystem, the marine species, and human health.
Causes of Water pollution
There are numerous reasons for water contamination or water pollution sources, starting from factors little to colossal scope. Before that, we need to understand what are water pollutants and water pollutants’ effects.
A pollutant is a substance or energy that creates adverse impact on the climate influencing an asset’s convenience. Contamination may cause long-or momentary harm by changing plant or creature species’ development pace or meddling with human civilities, solace, well-being, or property valuations. A few poisons are biodegradable, and along these lines, they won’t persevere in the long haul climate.

Types of water pollutants
We can classify Water pollutants into various categories based on different criterion
- Based on the source of the pollutant
- Industrial Pollutants: Diverse industrial poisons include chlorides, sulfides, carbonates, nitrites, nitrates of weighty metals, for example, mercury, lead, zinc, arsenic, and so forth, natural mixes incorporated for modern purposes, radioactive leftover, and so on. They are polluting rivers the most
- Agricultural pollutants: These are substance composts pesticides, bug sprays, herbicides, engineered synthetic compounds, weeds, and plant remains.
- Urban pollutants: These contain synthetic compounds from automobile exhaust, synthetic compounds from lime and substance manures utilized in the yards and nurseries inside the city, synthetics from metropolitan sewage, family sewage, and so forth.
- Natural pollutants: The regular contaminations incorporate volcanic cleans, debris due to landslides and disintegration, erosion and weathering brought about sediments, rotted and deteriorated natural products, and so on.
- On the Basis of Chemical and Phenotypic Characteristics
- Physical pollutants: Toxins changing the physical characteristics, for example, shading, taste, turbidity, silt, oil and oil content, broken down and suspended strong and so on.
- Chemical pollutants: These are chlorides, sulfites, sulfates, sulfides, carbonates, nitrates of hefty metals like mercury, lead, cadmium, and so forth, pesticides, herbicides, bug sprays, and a few other substance mixes.
- On the Basis of Degradation Nature
- Degradable pollutants: These contamination can be separated by organic methods, for example, decomposers or microorganisms. Such poisons are natural toxins. A few examples are leaf litters, sewage, trash, plants, and creatures.
- Non-Degradable pollutants: Organic methods can’t debase these contamination. These are inorganic poisons. A few examples are compound poisons and potent poisonous substances.
