Borewell water colour changes to yellowish black and smells
sanjukumar posted 3 months ago

10 years ago the borewell was dug. So far there is no problem. But a week ago, the borewell water began turning yellow with smell and foaming. After 3 days, it returned to normal but again turned yellowish a few days later. The sewage lines have been checked. There is no sewage line within 20 feet. Could it be an oil flake issue? This is in Chennai urban area with no industries nearby.

Water from borewell comes with mud
(not verified) posted 9 months 3 weeks ago

We have a submersible motor for apartment housing for seven families in Chennai. The depth of the bore is more than 100ft. Most of the time the water is turbid. Water should be available at a depth of around 60 ft. 

Any suggestions on what could be the cause for this? And what we can do to find out the issue?
