E-Flux products

E-Flux's Fossil Fuel Traps are designed specifically for measuring the biodegradation of Light Non-Aqueous Phase Liquids (LNAPL) such as petroleum in contaminated areas. These passive samplers utilize a patented dual-sorbent layer technology to capture CO₂ emissions from soil and groundwater, thereby providing precise measurements of Natural Source Zone Depletion (NSZD) rates. By differentiating between fossil fuel-derived CO₂ and natural soil respiration products, Fossil Fuel Traps allow for an accurate assessment of biodegradation without interference from non-contaminant signals. The traps are typically deployed for 14 days but can be adjusted to meet specific field conditions, ensuring robust time-averaged soil CO₂ flux estimates. By leveraging radiocarbon analysis, these tools support effective site management, facilitating decision-making in LNAPL source mapping and remediation efforts. Their non-intrusive nature and cost-effectiveness make them an invaluable asset for environmental risk assessment and management.

E-Flux introduces Clear-Well, an advanced solution for monitoring light non-aqueous phase liquid (LNAPL) distributions in soils. Unlike traditional monitoring wells, Clear-Well offers a non-destructive, UV-based method for high-resolution site characterization, making it a reliable alternative for environmental assessments. The patented technology (US Patent 10,677,729 B2, PCT 200-239793A) allows for repeated measurements, providing a time-dependent dimension to LNAPL data. The surveys capture pore-scale details, assisting in quantifying remedy performance and biogas production. Clear-Well's transparency enables detailed analysis of contamination profiles and soil lithology using both white and UV lights. Accompanied by proprietary software, the system translates digital images into depth-dependent soil saturation profiles, enhancing LNAPL site models, risk assessments, and remediation performance monitoring. Clear-Well is pivotal for understanding geochemical changes and natural depletion processes, ensuring effective contamination management.
