      You might check with your local USGS-WRD office,
http://water.usgs.gov/admin/wrd-dir/OH.html#HDR0 ,  to see about local
geological GIS data layers  and their existing well database  ( I believe
it's called NWIS) .   You will probably not be able to get the detailed
information  that it sounds like you want for each well from a generalized
geological GIS data layer.  From what I understand, drillers keep logs on
how deep they go and what kind of substrate they encounter as they drill (
x feet of sand, x feet of clay  ,etc. ) .  If your brother-in-law has such
information for each well, you can attach it to the geographic points.

Some background about what I want to do and hopefully someone can point me
the right direction. My brother-in-law drills water wells and some time ago
created a customer database so he could look up information about the well
drilled. The idea I have is to create a database of geological data for
well drillers and merge/link it to a database of their customers. The state

of Ohio now requires the well driller to include the latitude and longitude

of the new well when he submits his report to the state agency.

Other information they provide on that state report are the underburden
they drill through, such as, dirt, clay, sand, gravel, clay/sand,
gravel/sand, etc.

He has well records going back to when his father was in the same business
(about 50 years worth). So in general the goal is to take a wells
longitude/latitude and overlay that with a map of what was drilled through
create the well.

My confusion is where to find existing geological data that I can use as a
basis, can such data be imported (easily) into Postgis/Postgresql and well,

there are a number of other things but I don't want to make this post to

Any thoughts, pointers or suggestions are greatly appreciated.

"Trying"? My contribution was much closer to a "feeble wave in the general
direction of something that might lead you one step closer to a solution
if you squint really hard and do all of the work."
