When potable water is
contaminated by various sources like industrial effluent, solid waste, chemical
waste, hospital waste, agriculture run-off, nuclear waste, wastewater etc it is
called drinking water pollution. Drinking water is found in rivers, lakes,
estuaries, streams, wells, canals, water courses, distributaries. It is one of
the worst forms of pollution which directly hits the human health because life
can’t be continued without drinking water and it intake is must.
Harms of polluted drinking water
By consuming polluted drinkingwater likelihood of various diseases related to gastro, joints, digestive system, immune system etc increased manifold. Hundreds of thousands of people die every year due to water born diseases which is end result of consumption of drinking water.Main sources of drinking water pollution
Effluent of industries and
wastewater if flows into the fresh water bodies without being treated it reduces
the mineral features of that water and creates several negative elements in it
which directly hits the human lives if such water is consumed for drinking purpose.
Therefore, stress is made all over the world that industrial effluent and
wastewater must be treated before their final disposal. These two sources hugely
pollute the drinking water.
Agriculture run-off is the second
main sources of drinking water pollution as mostly farm lands are situated nearby
of the drinking water reserves either in river, lake or estuaries. Therefore,
the flow of agriculture runoff into them pollutes the fresh water and hits its
positive features. Agriculture runoff includes entire agriculture solid and
liquid waste including dry leaves, residue of pesticide, residue of chemical
fertilizer, residual water used in farming etc. It is advised that to reduce
the agriculture runoff, farmers must shift from chemical fertilizer to natural
fertilizers like they used to do so in ancient times and avoid using pesticide
unnecessarily besides arranging safe disposal of rest of the agriculture refuse
like dry leaves, waste crops, seeds etc.
Solid and hospital wastes if
dumped directly into water bodies are also one of the main sources of drinking
water pollution. In backward societies where awareness is lesser about these
menaces, such wastes are thrown into the fresh water bodies without feeling
their danger to health. Therefore, these wastes must be disposed of into
designated places instead of throwing them into drinking water bodies as these
are most harmful for human health.
As a matter of fact whatever - other than drinking water itself - is flowed into the water body causes drinking
water pollution and is quite harmful for human health. Therefore, it is advised
all over the world that drinking water is the most precious element which must
be protected from menace of pollution otherwise health of human beings will never
remain safe.
