As a field chemist at Ecology and Environment and Terracon, I operated a variety of Geoprobe's equipment. At E&E we had the third unit off the line in 1989. We put it through its paces sampling soil, soil gas, and water across the Midwest. The E&E unit did not have the gas chromatograph unit included. At Terracon we had 3 units, all equipped with GC's. Terracon also had the track mounted Geoprobe for accessing sample points on difficult terrain. I chased chlorinated solvents and leaking underground storage tank plumes in most states west of the Mississippi. I sampled water from as deep as 200' below grade. The data generated on the mobile GC setup matched CLP level III duplicate samples in almost all cases. We were able to collect many soil core samples from selected depths and analyze them on site for rapid determination of plume shape, size, and migration rate. This allowed for rapid deployment of remediation systems and rapid assessment of their effectiveness. I used Geoprobe generated data in multiple court cases to prove sources of soil and groundwater contamination. I miss my days putting holes in the ground. Review collected by and hosted on G2.com.
