Trap & Treat® BOS 200® technology has an outstanding ability to degrade soil and groundwater contaminants in-situ. Comprising activated carbon, nutrients and microorganisms it is an efficient and sustainable way to eliminate soil and groundwater contamination caused by hydrocarbons, organic solvents and BTEX-compounds. 

In-situ remediation involves minimum operational disruption as the carbon-based BOS® injectate traps and treats contaminated solvents in the ground. Site owners will soon experience a reduction in soil and groundwater contaminants and improved plume control. The BOS treatment keeps on working until the natural biodegradation process is complete – a process that takes from a few months to a few years depending on the contamination level.

This guided tour of in-situ remediation at a petrol station demonstrates the step-by-step process of biodegrading oil contaminants in soil and groundwater with Trap & Treat® BOS 200®.

Trap & Treat® BOS 100® is a safe and cost-efficient way to clean up soil contaminated by a variety of chlorinated solvents. The specially formulated particles protect groundwater throughout the clean-up cycle, neutralizing contaminants without leaving behind problematic daughter products. Leading science and years of experience have driven the development of this revolutionary remediation product, which is simpler and less expensive than most other available technologies.

How does it work?

Comprising activated carbon and non-valent iron, BOS 100® is injected into the ground as a slurry. The carbon traps the contaminants, which the iron particles then degrade through a reductive dechlorinating process. Unlike traditional iron treatments, the carbon carrier captures and retains hazardous daughter products, such as vinyl chloride, until dechlorination is complete. Routine monitoring will show a substantial reduction in contaminants after a few months – and their complete removal within a few years.

Before implementing a strategy for the remediation of soil and groundwater contaminants, we make a precise characterization of the contamination and all relevant environmental factors and installations in the affected area. Then we chose the preferred and most efficient remediation model in close dialogue with the customer.

Various remediation methods can be employed depending on the type of contamination. One technique is to dig out contaminated soil, tanks and separators. Another is to fixate and control the contamination to prevent it from spreading. Today, however, many prefer to make use of innovative in-situ technologies, where contaminants are tackled by injecting a special treatment into the ground.

Ejlskov is an expert in investigating the short and long-term risks to soil and groundwater. Whether soil contaminants pose a threat to groundwater or an environmental site assessment is required for a property transaction or construction planning, we tailor our services to your needs. We can also support the environmental decision-making of larger industrial companies and administrators of multiple sites. We asess environmental risks and advise on how best to manage or eliminate them.

All our recommendations are based on a thorough analysis of the soil and groundwater conditions at individual sites. That gives you the basis for making well-informed decisions about opportunities as well as liabilities – including your site’s alignment with local environmental legislation.
