Howdy damageisle,
The current "state of the art" for aquifer (well) mapping is
electrokinetics (sometimes called electroseismics) or EKS.
One of the leaders in this field is the UK based GroundFlow Ltd.
http://www.groundflow.com/frames/mainframe.htm
"The company was set up in 1994 and is dedicated to being the
leader in electrokinetics (sometimes called electroseismics),
providing reliable and effective equipment and services. These
systems use a sound wave to investigate subsurface rocks, and
electrical responses give direct details of water or hydrocarbons
within them."
Their web page titled "EKS Aquifer Mapping & Hydrology Surveying"
speaks to the process used and shows a sample map.

"The equipment collects the electrical signals generated by the
passage of seismic waves traveling through water-saturated rocks"
GroundFlow, Ltd. has some articles in Word 97 and PDF format you
can download at their page titled "SEEING BENEATH THE GROUND."

This includes an article in Word 97 format titled: "Electrokinetic
Techniques for Measurement of Rock Permeability" by J W A Millar
and R H Clarke.
If you do not have Word, you can download a free Word 97 viewer
from the Microsoft website.

There is the American company NorthWest Aquifer Surveying, Inc.
(NWAS) that uses GroundFlow's technology.

"We use ELECTRO-SEISMIC technology developed by GroundFlow to
provide solutions for your well locating and ground water needs!"
...
"NorthWest Aquifer Surveying Inc. WILL
- Help you find the right place to drill your well.
- Accurately estimate how deep you should drill your well.
- Help you avoid water with high salinity (Quality).
- ESTIMATE the quantity of water your well is likely to yield."
Although they are located in the state of Washington, they do
travel outside that area. They cover pricing, etc. at this
page on their website.
http://www.findwellwater.com/page6/NWAS6.html
"Survey (soundings per location for acquisition, processing and report)
Four 100m soundings on the same property ... $ 699.00
Four 300+m soundings on the same property ... $ 899.00
A minimum of four soundings is required to schedule a survey.
Additional shallow soundings (each) ... $ 170.00
Additional deep soundings (each) ... $ 220.00
The above prices reflect travel expenses for the Northwest.
Actual travel expenses may be added to surveys that require
travel outside the Northwest Aquifer Surveying current
franchise locations."
All of their "current franchise locations" appear to be in
the northwest United States. They can be contacted via their
toll free number at 866-740-6446.
As for dowsing, you might want to read the following article
at the James (The Great Randi) Randi Educational Foundation
(JREF) website.
http://www.randi.org/library/dowsing/
"The Matter of Dowsing from Swift, Vol. 2, No. 3/4 January,
1999"
There is a $1,000,000 (one milion dollar) prize that awaits
anyone that can show dowsing works and to date no one has yet
to claim the prize, although many have tried.
http://www.randi.org/research/index.html
"At JREF, we offer a one-million-dollar prize to anyone who
can show, under proper observing conditions, evidence of any
paranormal, supernatural, or occult power or event."
If you need any clarification, feel free to ask.
