Water - Black color - After Foam got settled
Hi,
Drilled Bore in our Apartment - Car Parking Area for a depth of 360 Feet two weeks back. The drainage Sump is more than 5 feet away. Two days back submersible pump has been laid. While we operate the pump, the first 5 minutes of water is clean and clear, however, in the next 25 minutes, the water gets black, and foam does come with a foul smell. After 25 minutes once again water is clear and no foul smell. Checked with our water surveyor who suggested the borewell point and he is also not clear with this kind of scenario.
Request expert advice, please.
