Holocene Drilling has conducted hundreds of environmental site investigations utilizing our auger, sonic and direct push rigs. A typical subsurface, environmental site investigation is intended to determine the presence or absence of contaminated soil and water in lateral extent and depth. 

Holocene is the most experienced and recognized environmental drilling company in the Pacific Northwest.  We operate a fleet of late model track and truck mounted rigs and support vehicles.

In addition, Holocene has acquired much of the assets and personnel of the former probe/injection company ESN. Part of this project involves bring on Anisa and Don Harnden, both experts in remedial injections.
