Sites that had chemical storage facilities or used chemicals in their operations are further investigated to determine subsurface soil and groundwater conditions.  All investigations are conducted according to industry standards and in compliance with the state regulations.  All investigations are conducted by the registered correction action project manager (CAPM) and all reports are certified by a professional engineer/geologist and Registered Corrective Action Specialist (RCAS). 

Phase II ESAs may include Geoprobe drilling, CME rig drilling, temporary wells installation, permanent wells installation, soil, and groundwater sampling.  

Using a Geoprobe unit during soil sampling is a very efficient way to determine soil conditions at sites with suspected contamination. 15-18 points can be sampled in one day.
