Question

Clear and transparent water is always fit for drinking. Comment.

Answer 1

Hint: We must think about all the aspects that make water drinkable like microbial and all. And also we must understand what contaminates the water.

Complete step by step solution:
Let’s start with what we perceive when we see clear and transparent water. Well, whenever we see clear and transparent water we always thought that the water is safe for drinking, but no, that’s not the case. The reason behind why clear and transparent water is not always fit for drinking is that there might be some contamination present in it which might lead to different diseases, infection and other hazards. Contaminations might be of different types such as microbial contamination, biohazards and chemicals; these three are the major contaminants that may be present as these three contaminations do not result in any change in colour.

Microbial contamination is due to the presence of microbes inside the water; here we are talking about pathogens (disease-causing bacteria). Since microbes are too small in size they rarely affect the colour and transparency of water unless they are present in huge quantities which leads to slime formation. Drinking such water which looks clear and transparent but contains microbes in it might lead to many serious diseases such as typhoid, cholera or even hepatitis A.
Biohazard contamination is due to the presence of biohazards inside water. Well, on first look the water seems all nice and drinkable but drinking such water leads to skin infections, body infections and other diseases.
Similarly, in the case of chemically contaminated water, the water looks all good for drinking but in reality, it is not drinkable and hence must be treated before drinking.
In houses, the water we use to drink and take bath is different even though they both are transparent and clear that is because one is treated and assured whereas the other is not treated and might be contaminated which leads to diseases if it enters our body.

Note: We can also know that the WHO (World Health Organization) suggest six litres of water per person daily to meet the requirements of most people under most conditions; and around 15 litres per person daily to cover basic hygiene and food hygiene needs.
