The eosFD uses the Forced Diffusion (FD) method to measure carbon dioxide (CO2) emissions and quantify the rate of contaminant loss of LNAPLs.  It is designed to facilitate better decision-making by providing customers with the highest quality, continuous monitoring data.

Monitor continuously

Having confidence in what’s happening at your site means you can minimize risk and make informed decisions about managing your site. Daily, seasonal and site specific conditions are known to cause large variations in gas fluxes and concentrations over time, which can only be captured using continuous monitoring. Continuous monitoring with the eosFD is the most robust way to monitor and quantify degradation rates because it captures this variability. In addition, it also reduces the time and cost involved in data analysis, which ultimately reduces the time it takes to make important remedial decisions.


The eosFD gas detection approach provides continuous, in-situ monitoring of CO2 released by biodegradation processes. Non-invasive surface methods are beneficial because they minimize disturbance to the contaminated system and potentially reduce the need for drilling. Consequently, this allows the instrument to report on the contaminated system without introducing bias. Most importantly, by reducing capital costs associated with installing monitoring wells, non-intrusive gas monitoring equipment like the eosFD provides significant cost savings.

Set and forget

Installing an eosFD is fast and easy, so you can stop spending hours tediously collecting samples in the field. The autonomous site monitoring capabilities of the eosFD reduces labour and associated field costs. It also eliminates wait times for third party lab analysis. In addition, the eosFD is a low-power device that is compatible with grid or solar power, providing the flexibility and adaptability for working with either urban and remote sites.
