Soil Sampling
Macro-Core® Soil Sampling
· 48 inch x 1.5 inch diameter samples
· Discrete sampling capabilities
· Depths of 40 ft. or more depending on soil conditions
· Preferred method of soil sampling
Dual Tube 21 Soil Sampling
· Collection of continuous samples from within a sealed casing of 2.125 inch OD probe rods
· Cased hole eliminates cross contamination while sampling through perched water tables
· Eliminates cave-in
· Retrieves 1.125 inch x 48 inch samples
· Perform bottom-up grouting of borehole retracting probe rods if necessary
· Install permanent pre-packed monitoring wells up to ¾ inch diameter

Groundwater Sampling
Screen Point 15 Groundwater Sampling
· Completely sealed during driving
· Greater depths reached
· Stainless Steel or PVC screens can be used
· 41 inch exposed screen length
· Fast recharge from formation
· Allows for grout to be pumped through rods string for proper abandonment
· Samples are collected using dedicated tubing and peristaltic pump
Mill-Slot Groundwater Sampling
· Sampling and profiling in sandy soils
· Samples collected using dedicated tubing and peristaltic pump or bailer
Temporary PVC Wells
· Can be left in place to collect water from clayey formations
· Fast recharge from formation
· Dedicated screens and risers to minimize cross contamination

Groundwater Monitoring Wells
Pre-Packed Well Screens
· Pre-Packed well screens in ½ and ¾ inch diameters
· Installed using DT 21 Soil Sampler and 2.125 inch probe rods
· No Cuttings generated
· Less disturbance to the formation
· Less purge and development water to dispose of
· Saves time and reduces costs
PVC Wells
· ¾ to 1 inch diameters
· Installed through open borehole
· Manually install filter pack and bentonite seal
· Quick and simple installation
Both well installation options can include permanent flush mount well protectors, if requested.

Material Injection Services
Material injection requires an experienced team coupled with specialized equipment.
Probe Technologies has been teaming with ORIN Remediation Technologies to provide clients with both.
Probe Technologies and ORIN have performed numerous material injections of various materials,
such as ORC® (Oxygen Release Compound), HRC® (Hydrogen Release Compound), EOS® (Emulsified Oil Substrate),
permanganates, catalyzed persulfates, and sodium hydroxide.
Probe Technologies provides equipment for both bottom-up and top-down injections.
Both procedures are summarized below.
Bottom-Up Injection Procedure
· The tool string is driven to the bottom of the injection interval
· The grout pump is coupled to the rod string
· The material is mixed and loaded into the grout pump
· The material is injected as the rods are retracted at a predetermined rate and flow
· The rods are retracted until the depth and volume is achieved
Top-Down Injection Procedure
· A pressure-activated injection probe is attached to the rods string
· The tool string with the pressure-activated probe is driven to the top of the injection interval
· The grout pump is coupled to the rod string
· The material is mixed and loaded into the grout pump
· The material is injected into the undisturbed soil
· The tool string is advanced 12-24 inches and the material is once again injected into undisturbed soil
· This is repeated until depth and volume is achieved
The advantages of using top-down injection techniques include:
· Eliminates preferential flow of injection material
· Lateral injection ports insure accurate placement of material
· Prevents "backflow" of injection material up through tool string
· No expendable points
· Works with ORC®, HRC®, permanganates, peroxides, acids, and other remediation materials |
