This case study highlights our ability to effectively assess complex hydrocarbon plumes with 50-foot groundwater fluctuations at a multi-plume industrial site using 20 sensors and LiORA Insights to monitor and assess 3 distinct plumes.

Achieving $49,500 in annual savings by transitioning from quarterly to annual sampling utilizing 6 sensors for enhanced groundwater dynamics correlation and reduced operational costs.

The National Park Rapid Plume Assessment showcases the efficiency of LiORA Trends real-time modeling, utilizing 8 sensors to deliver critical insights in a fraction of the time. Get insights on your plume immediately rather than years or decades.

This case study highlights significant savings from risk-based closure strategies, achieving $400,000 in sampling costs with the deployment of 16 sensors + LiORA Insights over just two years.

Remediation methods, such as soil vapour extraction and in situ chemical oxidation are challenging in cold, low-permeability conditions, highlighting the need for alternative approaches. Using naturally occurring microorganisms to deplete hydrocarbons is attractive. However, it is challenging to repeatably execute this remediation technique successfully across multiple sites due to nuanced site mineralogies.

Natural Source Zone Depletion (NSZD) refers to microbial and physical processes that reduce hydrocarbon content in the subsurface. Microorganisms degrade hydrocarbons deep in the soil and rapidly deplete available oxygen and other electron acceptors in the soil and groundwater.  At that point, microorganisms begin to ferment hydrocarbons, producing organic acids. These organic acids are used by a group of microorganisms called methanogens, which consume these organic acids and release methane. The methane migrates towards the upper layers of soil, where another group of organisms, called methanotrophs, consume the methane and release carbon dioxide as a product.
