Fuel Fluorescence Detection of Contaminants in Surface Soil and Subsurface Soil. How does Fuel Fluorescence work with Environmental Cleanup?


Vertek's line of fuel fluorescence detection (FFD) products are rapid site characterization tools that measure fluorescence produced by the polycyclic aromatic hydrocarbon (PAH) constituents of petroleum, oil, and lubricant contaminants.

Cost Effective Alternative to Laser Induced Fluorescence (LIF)


The FFD probe utilizes solid state Ultra-Violet 

(UV) LED excitation sources and multiple spectral response bands, all tunable to maximize discrimination and delineation of subsurface contamination. With their long life and broad angle of view for maximum sensing area, the UV LED excitation sources provide a cost effective alternative to laser induced fluorescence (LIF) (e.g. UVOST) techniques.

Vertek's innovative FFD sensor package is robust, low cost, and tunable to discriminate multiple contaminants of interest. Competitors using LIF often string many meters of expensive fiber optic cable from the probe to the up-hole sensing and analysis equipment. All Vertek FFD probes collect and process data down-hole, with no complicated instruments to operate or complex data to interpret. Sensor output provides continuous readings with depth with a screening level (high/medium/low/no) response to contaminants. High concentrations of contamination will exhibit a negative response and/ or absorbance.

Each FFD sensor band, (up to 3 available), is tuned to the peak fluorescence response of the contaminant of interest, allowing immediate verification of contamination at a fraction of the cost and complexity ofLIF (e.g.UVOST). The Vertek FFD sensor package was designed with cost savings in mind.


In-Situ Video

video-probe-2Another tool to visually confirm the presence of contaminants prior to sampling saving laboratory time and money! A great tool for the dynamic site investigation and Non-Aqueous Phase Liquid (NAPL) plume confirmation.

The video cone is a similar module to the FFD where it can be attached to a CPT cone or pushed alone. When utilized to verify or view subsurface media the real time video is easy way to validate your previous investigative activities. All video is recorded and can be edited to highlight the areas of interest.video-probe

The Video module can be used in series with the FFD module creating a dual purpose combination tool that can identify the presence of hydrocarbons and visually verify them at the same time. This and other environmental products manufactured by Vertek have been used in many elements of the Environmental Protection Agency (EPA) hazardous site investigations utilizing the Triad approach.


Modular Soil Sampling

Vertek’s patented Soil Sampler is built for reliable, cost-effective retrieval of soil samples in difficult geologies and is designed to be deployed by most common CPT equipment.

Soil_Sampler_BWCycleable and Reliable

The patented tip release system is strong enough to withstand heavy push loads in stiff soils, yet reliably retracts at the desired depth.

Our field replaceable wear surfaces are made from hardened alloy steel.

Simple Operation

The sample barrel with retractable tip is pushed to the desired depth, a lanyard lowered through the push rods then retracts the tip back into the catch housing. After tip release the lanyard is removed back to the surface and soil sampler is ready for sampling. The sampler and the rod string are then retracted, bringing the sample to the surface. Removing the tip releases the soil sample for ease of Examination and logging. Longer samples can be obtained by threading multiple sample barrels together. The sample sleeve can be clear plastic, stainless steel or split stainless steel depending on sampling requirements. The sampler can be rapidly disassembled for field decontamination.


Conesipper® Soil Gas Sampling

Simultaneous In-line Sampling

The Vertek ConeSipper® module attaches directly behind a standard CPT cone to obtain soil gas or water samples as the CPT probe is advanced, saving substantial money and time by eliminating duplicate soundings. Developed and patented by Westinghouse Savannah River Corporation (WSRC) and Applied Research Associates, Inc., the ConeSipper® is New_ConeSipper_002_cutoutmanufactured by Vertek under an exclusive license to WSRC.

System Description

The ConeSipper® module contains a two stage stainless steel filtration system, an integrated pneumatic valve system, and an 80-ml stainless steel sample chamber. A non- absorptive conduit brings the sample to the surface from depths of more than 200 feet. A pneumatic control box on the surface meters the flow of inert gas to the module, controls the rate of sample collection, and allows the ConeSipper® to be purged and decontaminated down-hole.

High Quality Sampling

The ConeSipper® uses a dual filtration system to obtain samples that are generally free of sediment. The primary filter prevents sand from entering the ConeSipper®, and a secondary filter, removes clay and silt particles. The ConeSipper® does not require a vacuum in all circumstances, which can strip volatile compounds from the sample ensuring more representative samples. Vacuum usage is optional with your Conesipper®.


The ConeSipper® body is made from high-strength stainless steel to withstand the push forces of a 30-ton CPT truck, and features industrial grade pneumatic valves.

Simple Operation

The sample flows into the chamber under ambient pressure through a check valve that prevents back flow from the chamber. Once the ConeSipper® is full, gas pressure is applied through one of two pneumatic control tubes and the fluid is pushed up to the surface

through the second tube. Compressed inert gases can be used to maintain strict sample quality standards. Both filters can be removed for cleaning or replacement without disassembling the ConeSipper® from the CPT probe, greatly improving production rates.

Fast, Cost-Effective, Multi-level Sampling

Remote (water or gas) flushing of the ConeSipper® internal chamber is a significant advantage over other CPT sampling tools as samples can be obtained from multiple depths without returning to the surface for cleaning. A rinsing fluid (e.g., distilled water) can also be ejected through the filtration system, allowing the operator to verify decontamination of the sampler by checking the cleanliness of the flush fluid, afterwards the probe can be pushed to the next sample depth. This capability is a significant economic advantage on jobs that require interval sampling.


Grouting Tools and Cone

To meet the growing needs of various contractors and state and federal agencies Vertek offers our self grouting tools which allow grouting of CPT holes while removing the rods. Vertek offers two types of grouting tools to fit your needs.grout_cone_cut_out


The Self-Grouting Module is installed in the rod string above the cone and grout is pumped through during withdrawl. The sacrificial ring fits around the module and comes off when the rods are retracted. The design of the module does not allow for cycling and is not recommended for areas with very fine materials.


This Self-Grouting Module is comprised of a standard cone with blow-out plugs that allow grout to be dispensed during extraction. When the grout is pumped through the tube, the plugs are forced out and grout is released through two outlets.

Cost and Time Efficient

Vertek’s Self-Grouting Modules save time and labor by allowing the operator to grout the hole without extracting the rods and then filling the hole by hand. Instead, the operator can seal the hole as the rods are being retracted and all this can be done from the operator control station.

3367_3377Post-push Non-Cycleable Grouting Adapter (tremie method)
An additional method of grouting utilizes Vertek’s Post-push grouting system, which requires a second push but is a simpler method than when combined with the CPT push. Our tremie adapter is applied to the end of the rod string with a disposable oversize tip. Tremie method requires a second set of push rods and associated grout mixing tools.

Vertek’s Self-Grouting Modules run the grout tube through the center of the rods alongside the standard CPT cable through the innovative Grout Module Housing which allows the operator to run a probe, extract, and grout without work stoppage.


SMRT Module - Soil Moisture-Resistivity

Soil Moisture/ Resistivity 

Soil moisture, or the volumetric percentage of water in soil, has  become an important consideration in the design of environmental re mediation processes  and agricultural planning, and it is one of the most fundamental factors influencing soil  strength. VERTEK’s Soil Moisture/Resistivity (SMR) Module provides real-time, in-situ logs of soil moisture and resistivity without sampling.


Soil Moisture Measurement

The SMRT module takes advantage of a relationship between the soil dielectric constant and moisture, widely known as Topp’s Equation. The SMRT module utilizes high frequencies to minimize the impact of soil type. 

Resistivity Measurement 

The SMR module takes advantage of a relationship between the soil dielectric constant and moisture, widely known as Topp’s Equation. This relation-ship is not strongly influenced by soil type and resistivity if the dielectric measurement is made above a critical frequency of approximately 30 MHz. The inner two electrode rings of VERTEK’s SMR module determine the soil’s moisture content by measuring the frequency  shift of a high frequency excitation signal as it passes through the soil near the surface of the module.

Resistivity Measurement 

The outer two rings of our four-electrode ring design are used to measure resistivity. An AC voltage signal of constant amplitude is applied across the rings. A voltage measurement, which is proportional to the current through the soil, is made across a sampling resistor. The VERTEK Data Acquisition System and proprietary software provide a soil resistivity readout in ohm-meters.


Geotechnical and Environmental Applications

SMRs are available in a variety of diameters and configurations for use in a number of applications, including geotechni- cal, environmental, and agricultural. An SMR Module can be used in conjunction with a CPT cone to provide soil moisture/resistivity data simultaneously with tip, sleeve, and

Long Term Monitoring

An array of SMR probes can be permanently emplaced with a field-based data logging or acquisition system. Several communications options (cabled and wireless) are available for long-term monitoring to optimize irrigation of high value crops and to detect leakage into or from landfill areas and hazardous waste sites.

Reliable, Cost-Effective

The SMR module does not require delicate tuning or complicated maintenance and can be field calibrated using water and air. Continuous moisture logs can be generated at the standard CPT advance rate of 2cm (one measurement) per second, so moisture surveys can be completed with the geotechnical site characteriza-
tion at no additional operating cost.


The SMR module fits behind a 15 cm2 cone and works with Vertek’s Data-
Pack 2010SV or Mini Datapack. No additional software is required.
