Solution(By Examveda Team)

Peculiar smell coming out of water is due to H₂S.
Hydrogen sulphide is a colourless, flammable gas that smells like rotten eggs at low concentration levels in the air. It is commonly known as sewer gas, stink damp, and manure gas. At high concentration levels, it has a sickeningly sweet odor.
