Of all the in-situ remediation solutions on the market, we have found only one that is truly effective. That’s a solution with the capability to trap the contaminants in the soil and groundwater and hold them in place while they are broken down and eliminated. 

When they came up with the idea, the developers at US-based Remediation Products Inc. understood one important thing – that the well-known ability of activated carbon to absorb contaminants could be enhanced. This is why they added bacteria and nutrients. The role of the bacteria is to feed on the contaminants, while the nutrients supply the bacteria with the energy they need to keep going.

An ongoing process – until the job’s done

After injection of the carbon slurry, soil and groundwater contaminants are first absorbed and then gradually consumed. This frees up capacity for the carbon to absorb more contaminants for the bacteria to feed on. And so the process goes on, until the contaminants are finally removed over a period of a few months to a few years, depending on the site. Once complete, the bacteria die out, and the nutrients in the soil return to pre-treatment levels. This patented product for the treatment of hydrocarbon contamination is marketed as Trap & Treat^® BOS 200^®. Another product – BOS 100^® – is available for chlorinated contaminants.
 

Supervising a successful remediation

In my work as site manager, the Trap & Treat^® products are my most important tools. On site, my role is to supervise the crew responsible for injecting the right amount of product in the right places underground, using the remediation plan as our guide. We always keep health and safety in mind in the process. The plan is based on detailed site characterisation data and a 3D model of site contaminants. This gives us the basis for carrying out a successful clean-up project. Occasionally, we have to make a few adjustments when putting the plan into practice. In that way, we ensure the job gets done in the best possible way. One of the beauties of both BOS 100^® and BOS 200^® is that the whole process takes place underground. We don’t have to take any soil or groundwater away and treat it somewhere else. For some of our clients, this ‘invisible’ treatment is important. So, although initially the cost may seem high, it really is a very cost-competitive solution when all things are considered. The only extra costs after injection pay for the monitoring of your soil and groundwater conditions. That’s it!
