Envirotech runs three (3) Hollow Stem Auger (HSA) rigs, a track mounted CME-55, a truck mounted CME-55,
and a truck mounted CME-75. Our HSA rigs can be tooled to drilling using air rotary or mud rotary if site lithology requires it.

Additionally, Envirotech runs seven direct push (Geoprobe) machines. Five of which are AMS 9510s, and two Geoprobe 7822s.
All seven units can spin Hollow Stem Augers for shallow wells, or flight augers in hard formations.

Our drilling equipment has a preventative maintenance program in place where hydraulic hoses on all drilling rigs are
inspected every 6 months by a third party technician, and any fatigued hoses are replaced.
