We dug a borewell last week at a depth of 650 feet . We have checked with the camera and we have countered loose boulders or stone at a depth of 500ft. We cannot insert perforated pipe because of uneven boulders present, which may damage the costly pipe. The water level started from 300ft itself while the source of water is from 350 ft. Could you please suggest to me what needs to be done?

Thanks
