Solinst Drive Point Profilers (DISCONTINUED)

  • Contaminant vs. depth profiling
  • Detailed plume delineation
  • High Quality Groundwater Samples
Product Options



The Model 660 Drive-Point Profiler is designed to be a preliminary site assessment tool enabling the collection of groundwater samples from multiple points in a single drive/drilling location, at discrete zones.

Profiler transects allow:

  • High resolution sampling
  • Detailed plume delineation
  • Depth vs. Contaminant profiling

The Profiler and attached AW rod is pushed, hammered or vibrated into place by the rig to the desired depth in suitable sands. The Profiler is stainless steel with a 45 mm (1.75”) diameter, with one row of screened inlet holes set circumferentially leading to a single LDPE or PTFE/FEP stainless steel sample line.

Sealing Profiler Holes

In most homogeneous sands, the hole will collapse as soon as the Profiler is removed. In other geologic formations it is best to use a Grout Tip Profiler. Gout Tip Profilers have single use tips which allow it to be disconnected from the Profiler by injecting grout under pressure using a grout pump after sampling is complete. This seals the hole as the Profiler is being withdrawn, to ensure no void spaces.

Depth Discrete Sampling

Profiling can either start at ground surface, or at the bottom of a predrilled hole to save time.

The Profiler system is flushed with deionised water using a Peristaltic Pump whilst being driven between sampling zones, to avoid downward drag and cross contamination. When the desired depth is reached, the pump flow is reversed, resulting in water flow to the surface. This water is then monitored for clarity and conductivity. The sample is taken when all deionised water has been removed from the system and purge parameters have stabilized.

After sampling, the water flow is reversed and once again deionised water is used to flush the Profiler tip, to keep it from clogging. If correct procedures are followed, there is virtually no drag down as tests have proven.

Sealing Profiler Holes

Drive-Point Profilers are not suitable for all sites as depth limitations vary with soil conditions and the drive technology being used. Using a peristaltic pump to flush and sample is effective if the water level in the borehole is within 8 m (26 ft.) of surface.

615 Drive-Point Piezometers – Direct push/drilling methods

601 Standpipe Piezometers – Placed in a borehole or test pit

660 Drive-Point Profilers – Typically the limit is 9m below the water surface.

615 Drive-Point Piezometers – Typically 2-3m in loose deposits.

601 Standpipe Piezometers – Can go as deep as required.

615 Drive-Point Piezometers – Screened tips available in 6” and 1ft lengths. Can have a compression fitting, hose barb, or no barb as well as shielded options.

601 Standpipe Piezometers – Screened tips are available in 6”, 1ft, 2ft, and 3ft. These use a Vyon® filter.

The 601 and 615 are designed for permanent monitoring. So, neither are reusable, but the 615 can pulled out mechanically. However, grouting is the most favourable method of decommission on both of these pieces of equipment. The 660 Drive-point Profiler is a short-term monitoring point, therefore the hole left behind can be easily grouted using a grout tip Drive-point profiler.
The depth that these can be installed to depends on the material in which they are being installed in. Typically, you will get a deeper installation in peat over other ground materials.
