Here in Indiana, shallow wells are not allowed, and all wells are required
to be grouted.
A good website to better understand well requirements is presented by the
Illinois Department of Public Health.

PS I feel your (very) mistaken about the grout in a well.

You must have misunderstood. casing should be placed in hole that is
drilled 10 inches round down 2 feet into bedrock, with 6 inch well
casing. minimum 20 feet, with grout 2 feet into bedrock all the way up
to surface, with casing 8 inches minimum above grade, 2 feet above
grade minimum in flood plain or higher

Not a clue regarding pipe. I do have a thought on drill heads though.
Diamond bit heads are nice, they cut through stone and anything else very
quickly, however they also create a lot of dust in doing so. That dust has
a tendency to get pushed down the hole and clog the first few water veins
you would have come across. Typically in this area, conventional head
drills find water in the 60 to 80 foot range, diamond bit heads typically
find it in the 150 - 250 foot range. Based on this "local? statistic, and
the assumption of paying by depth, not time, conventional head drilling is
cheaper. Not to mention less pipe required.
