Is it an oily smell? It coud be cos the pump is new. Just run it for a considerable period and the smell will go away. If smell is of stagnant water, incorporate some quantity of alum in borewell. Difficult to quote an exact quantity. Incorporate in borewell and let water stand for about 5-6 hours. See if the smell reduces when water is next drawn. If successful, repeat the cycle.

Add ‘Sodium bicarbonate’ (edible grade, TATA make) 5 Kgs pour directly within borewell by sliding the borewell casing cap and leave it for 24 hrs, later pump out the water for atleast 2 to 3 hrs until you get fresh water without any foul smell.
