The Team Prepares To Drill....
 This is the powerhead, the "heart" of the machine. |
 The rig breaks down into easy-to-transport items. Standard 1" plumbing pipe (not pictured) is used as drill stem. |
.
On one occasion, our crew drilled down 30 feet and pulled up a core sample of clay. The second time,
(shown here) we drilled down 12 feet through a difficult broken formation and pulled up a cored rock sample.
 |
 Water is injected down the drill pipe with a 2 horsepower gasoline-powered pump. |
 Two different drill bits were used, a tungsten carbide soil bit, shown here (for softer formations such as soil, shale, or clay), and a diamond tipped coring bit (for harder formations such as sandstone or limestone) |
