We had done a Geological survey as per the expert's recommendation we prepared
to go for a bore. The recommended depth for water source was app. 1000'-0.

On 05-06-08, we drilled bore (6.5"size) well in our apartments.We went up to
350'-0 and the driller told that loose soil(below 6 mm metal size - Grey in
colour) was found and could not drill further as the same collapsing when the
drill bit was taking out. At 350'0 we found water size approximately  one
inch only.

PVC casing pipe was put up to 80'0 from the top. We were told that after 100'-0
rock was found and below that the loose soil was found. Now the  depth of
bore well was around 170'0. (after further collapse).  The driller could
not put the Perforated casing  from 300'-0 to 350'-0. Having put the same
the drill might have been gone further.

We would like have expertise opinion regarding the following.

a) How to over come this problem?
b) Can we use the same bore for re drilling and perforated casing can be used
or  not? If so How to go about it?
c) If option (b) is not feasible at what distance we have to drill the new bore
and how to go about it?
d) Is there a solution for the same?

Kindly provide advice.
