The 660 Drive-Point Profiler allows collection of groundwater samples from multiple points, at discrete zones, in a single drive. This allows a detailed vertical profile with only one drive of the rig. The profiler tip is connected to a Peristaltic Pump which flushes the profiler tip with de-ionized water during driving to prevent cross contamination and is reversed to obtain a sample. It allows detailed plume delineation quickly and inexpensively. An expendable grout tip is available to allow easy decommissioning.
