Soil Gas Vapor Sampling Systems: Points vs. Probes

EON Products offers a variety of soil gas vapor sampling systems and equipment to help environmental consultants and project managers collect and sample soil gas vapor from shallow depths, either by using temporary soil probes or permanent soil gas points. 

Soil Vapor Points

Soil Gas Vapor Sampling Systems: Points vs. Probes - EON Products

Soil vapor points are a low-cost option for soil gas vapor sampling. They are small, dedicated stainless steel points that are configured with vapor ports for gas inlet and a hose barb on the backside for sample tubing. 

These devices are installed into a small drilled hole or pushed into place with extension rods and left in-place indefinitely. The ports are protected from debris by a screen and are shielded from failing soil debris by an optional umbrella disk. 

Soil vapor points are ideal for obtaining samples from beneath the soil’s surface or beneath slabs when monitoring hydrocarbon spills, tank and pipe leakage, landfills, hazardous waste sites, and intrusive vapors.  

Soil Gas Vapor Probes

Soil gas vapor probes are reusable stainless steel devices that can temporarily extract vapor from up to four feet below the soil’s surface.

The probe is manually pushed into place with a rigid extension rod and a T-handle or drive hammer. Inner rods prevent soil from entering the sample during driving and are removed for sampling. Sample tubing is attached to the top rod to extract the vapor sample. The probe is removed after sampling.

Soil gas vapor probes are useful instruments for checking beneath the soil surface when monitoring hydrocarbon spills, tank and pipe leakage, and hazardous waste sites. 

No matter the project, EON provides a selection of the finest-quality soil gas vapor sampling systems that can be used in many applications.

The Dangers of Soil Vapor Intrusion

Soil vapor intrusion is the process by which volatile chemicals move from a subsurface source into the indoor air of overlying buildings. 

How does it work?

Soil vapor or gas is the air found in the pore spaces between soil particles. Because of a difference in pressure between the vapor in the soil and the interior of the building, the vapor enters buildings through cracks in slabs or basement floors and walls, as well as through openings around pipes and electrical wires. Heating, ventilation or air-conditioning systems may also create a negative pressure that can draw in the contaminated vapor.

The Dangers of Soil Vapor Intrusion - EON Products

Soil vapor can become contaminated when chemicals, such as volatile organic compounds (VOCs), from subsurface sources enter the soil. Subsurface sources may include contaminated soil and groundwater. If contaminated vapor enters a building, indoor air quality may be affected. 

What chemicals are involved?

VOCs are the most likely group of chemicals found in soil vapor. These may include solvents used for dry cleaning, degreasing, and other industrial purposes. Petroleum-related VOCs include benzene, toluene, styrene, hexane, and xylenes. 

VOCs are also found within many household products, including paints, glues, aerosol sprays, air fresheners, new carpeting or furniture, lubricants, refrigerants, and cigarette smoke. 

These commonly used products may find their way into the soil from industrial spills, leaking underground storage tanks and pipes, illegal dumping, and improper drum storage. At the consumer level, disposing of used motor oil, paint and cleaners on the soil or into a stream can create and contribute to soil vapor contamination.

What are the risks?

Current and potential exposures are considered when evaluating vapor intrusion at a site that has documented subsurface sources of volatile chemicals. However, exposure to VOCs does not mean health effects will occur. Health effects depend on various factors, including inhalation exposure, the length of exposure, the frequency of exposure, and the toxicity of the chemical. 

The Dangers of Soil Vapor Intrusion - EON Products

How is it investigated? 

To properly investigate and examine the extent of vapor contamination on a site, four types of environmental samples can be collected: soil vapor samples, sub-slab samples, indoor air samples, and ambient air samples.

EON Products offers several types of soil vapor sampling systems and equipment to help you collect and sample vapor from shallow depths, either by using temporary soil probes or permanent soil gas points. We also provide environmental field supplies, including samples bags, gloves and more.

What are PFAS Chemicals?

Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals that are manufactured and utilized in a variety of industries worldwide. Despite the commonality of these man-made substances including PFOA, PFOS, and GenX, PFAS have been shown to have a correlation with negative health effects.

The Risks Associated with PFAS - EON Products, Inc.

Where can you find it?

PFAS commonly finds its way into surface water, groundwater and drinking water supply from sources including landfills, wastewater treatment facilities, and even firefighter training area where PFAS in fire-fighting foams soaks into the soil and is carried away by runoff from rain. Once in the soil and water, this substance accumulates and finds its way into living organisms, such as plants and fish, and then up the food chain to humans. Food is often grown in soil that contain the substance, and prepared foods are often packaged in PFAS-coated wrappers. Many common household products contain the substance as well, including but not limited to: paint, polishes, waxes, cleaning products, and water-repellant fabrics. 

There is an extensive list of consumer products that contain these chemicals, including cookware, pizza boxes, stain repellants, and clothing.

What are the effects of PFAS?

Animals and the human body are not equipped to break down PFAS, which means these chemicals can build up in organs and tissues. Animals that have been exposed to PFAS exhibit changes in liver, thyroid, and pancreatic functions. Increased cholesterol levels are one of the leading effects of PFAS exposure in humans. Other consequences can include low infant birth weights, depreciated immune systems, thyroid hormone disruption from exposure to PFOS, and even can cancer from PFOA. 

How can you reduce PFAS exposure?

If you live in or near an area impacted by PFAS contaminants, you can check with local water boards to see if there are any advisories in effect for drinking water. the Interstate Technology Regulatory Commission (ITRC) is an organization of technical professional that have published Fact Sheets and informational documents on PFAS and other compounds that affect human health.

Additionally, the United States Environmental Protection Agency (EPA) has made significant progress under the PFAS Action Plan to help states and local communities address the substance and its effects, and protect public health.

The Risks Associated with PFAS - EON Products, Inc.

EON’s solution

Much of the drinking water and agricultural irrigation in the U.S. comes from groundwater. Monitoring groundwater for PFAS and taking action to reduce the impact of contaminated groundwater is of critical importance to preventing its spread throughout the food chain. EON Products manufactures and provides passive groundwater samplers to environmental monitoring consultants, who then use these devices to accurately sample virtually any compound in the groundwater including; VOCs, Metals, Semi-Volatiles, 1,4 Dioxane, and Per and Polyfluoroalkyl Substances. Users experience all the ease of use and cost saving benefits of passive diffusion sampling plus verified performance on sample results for the low concentrations, to less than 2 parts per trillion, of some of the more commonly detected PFAS in the environment.

Our PDBs are made from materials that do not contain PFAS and have been listed as acceptable materials for sampling this substance. And, because they are immersed in the aquifer water for an extended time, concentrations in the groundwater are able to equilibrate with the PDB sampler materials before the sampler is removed, virtually eliminating the potential for low-bias caused by absorption to the sampler materials.
