Bore water colour changing to brown

Bore water not usable for drinking

This is Vinay here recently have constructed my home near Bannerghatta Road in Bangalore, where in have drilled a borewell to 850 feet. The water force was so much that I couldn't drill further. Once I started using the water, I noticed it changes to brown colour and smells bad i.e. once I start the motor, the water colour looks pure but if I store that water in any vessels after 30 minutes water colours turns to brown colour which we can't use for any purpose. Request for advice if I need to take any actions from my end since have inserted completely one length pipe.
