Characterization Tools Engineered for Precision
When it comes to remediation, guesswork is not an option.
E-Flux’s powerful characterization tools give you the expert measurement you need- backed by solid research and trusted across the industry. Our technology helps turn site data into clear, actionable insights, so you can move forward with confidence.
Fossil Fuel Traps
The most precise Natural Source Zone Depletion (NSZD) monitoring tool
Fossil Fuel Traps are sorbent-based passive samplers that measure naturally occurring biodegradation of Light Non-Aqueous Phase Liquids (LNAPL, including petroleum) by capturing the CO₂ emitted from contaminated soil and groundwater. They provide:
Multi-day, time-integrated average flux measurements to account for diurnal fluctuations.
Patented dual-sorbent layer technology to avoid atmospheric CO₂ interference with soil gas respiration.
¹⁴C analysis to differentiate fossil fuel-generated CO₂ from modern CO₂ interference.
Decades long experience with petroleum contaminants, now also shown to be applicable to chlorinated solvents.
Clear Well
Non-Destructive UV surveys of LNAPL distributions in soils
Clear-Well is a transparent port surveyable on demand using a portable instrument. These repeatable surveys enhance understanding of mechanisms driving LNAPL mobility and stability at field sites under changing conditions. Our surveys offer:
Measure LNAPL distributions at the pore scale, providing quantitation of remedy performance, natural source depletion, biogas production, LNAPL mobility and soil geochemical changes.
Signals from white and UV lights on every location reveal formation lithology over layering the contaminant distribution.
Our proprietary software transforms digital images into depth-dependent soil saturation profiles.
Advancing the Future of Site Characterization
Publications
Our library of peer-reviewed publications, technical papers, and third-party studies provides in-depth insight into the methodologies and data that supports effective remediation strategies.
Case Studies
A collection of real-world projects demonstrating how our technologies are applied to measure NSZD, evaluate remediation performance, and support data-driven site management.
NSZD Monitoring
Quantifying NSZD rates can be valuable in determining the appropriate timing, scale, and aggressiveness of LNAPL remediation efforts. Learning the science behind NSZD is a key resource for site characterization.
