The pollutants that contaminate the quality of water are known as ‘Water Pollutants’ such as human excreta, wastes from household kitchens, toxic and radioactive substances, etc. Most of the water pollution occurs due to wastes released by chemical factories, oil factories or oil spill accidents. Here are the major causes of water pollution:

1. Living Wastes:

• Human or animal excrete contain various microorganisms that cause diseases amongst the living, the release of this excreta in water poses a major to water and thereby affecting the living too.

2. Toxic Wastes:

• Wastes released from factories are usually toxic, dangerously treated with chemicals and sometimes there are even nuclear wastes disposed of in water such as uranium, radon, etc. Along with this, there are also chemicals released in water after the completion of their use; chemicals such as pesticides and insecticides, soapy water, etc; and these chemicals can be organic or inorganic chemicals.

3. Plant Wastes:

• These are organic wastes where nutrients in plants such as nitrated and phosphates produce fertilizers or manure which are actually harmful to the plants.

4. Kitchen wastes:

• The wastewater produced by household or restaurants kitchens carry many harmful microorganisms that lead life-threatening diseases, these microorganisms are responsible for diseases like Malaria. These microorganisms then become breed on other creature which acts like their carriers and these carriers infect an individual who in turn infects someone else and the cycle keeps going.

5. Modernization:

• As population size increases, the demand for basic needs like shelter, food, etc also increases. Therefore to produce these needs one needs space and land, and land can be occupied by either destroying natural surroundings present on land or drying up water bodies and occupying those lands.
