With
the 2012 National Ground Water Association (NGWA) Groundwater Expo set for Dec.
4-7 in Las Vegas, I have decided to write a few thoughts about previous NGWA

There are many small, portable drilling machines
manufactured all over the world that I would classify as wannabe drills-drills
that are purchased by well-meaning nonprofit charities, church groups and
others to drill water wells in developing countries.
