QUESTION
Mud in borewell water due to rain in Chennai, TN - Want to know if this is temporary and need solutions to the problem

Facts: We have dug the borewell in the month of August 2009 for 260 ft. and fixed the submersible pump at 250 ft. Upto november 2009, the water was clear when the rain started. After the rain, the water became muddy.

Actions taken: 1. Stopped drawing water from the borewell for few days in order for the mud to settle down.

                      2. Water was released to our gardens at a rate of 5 hours per day for a few days.

                      3. Due to the above actions, the level of mud in the water reduced, though not fully during the months of                           December, 2009 and January, 2010.

                      4. On February 15th, Lifted the pump by 25 ft. above and noticed the same level of mud in the water.

Suggestion Received: We have been suggested to flush out the borewell using compressor, to remove the after effects of rain.

Questions: 1.Is the suggestion valid?

                 2.Are there any other solutions?

                 3.Is this a temporary problem?

                 4.We have an alternate well to meet our water requirements. Hence, suggest long term as well as short term solutions.

P.S. The digging of borewell was properly supervised and there could be less chances of any defect in the bore.
