Bioclear earth founded in 1988 was the first company in the Netherlands that developed and implemented technique for biological soil remediation. Biological soil remediation is a great example of how we cooperate with the power of nature. Nature’s resourcefulness and her ability to recycle almost everything that finds its way into the soil are remarkable. In an area with pollution, bacteria start to evolve and adapt to these circumstances by using the contamination as their food resource. The pollution is slowly degraded and the soil is clean once more.
In many situations we want to get rid of the contamination as quickly as possible, because of the hazardous effects it can impose on our health and the environment. That’s why Bioclear earth developed techniques to speed things up. We can stimulate the bacteria already present in the soil to degrade the pollution faster. We feed the bacteria a special diet, which gives them a turbo boost.
Not every location is fortunate enough to already house the right bacteria. However, this is no problem. We can solve this by injecting specific bacteria in the soil and adding extra food resources. These bacteria will immediately start to do their good work and break down the pollutants.
There are many different soil contaminations that we can remediate with this method: for instance contaminations caused by dry cleaners, petrol stations, industry or agriculture. In the Netherlands alone there are over 60.000 polluted locations that require remediation. The European Environment Agency reported that there might be as many as 2.5 million potentially contaminated sites across Europe, which need to be investigated. Approximately 14 % (340 000 sites) are expected to be contaminated and likely to require remediation.
Contaminants that are suitable for biodegradation are:
During the remediation process we take soil and (ground) water samples to monitor the process. Through our knowledge of and experiences with biological processes, we only carry out the most necessary analyses, until the contamination is degraded. This can take up from a few months to several years.
A great advantage of biological remediation is that it does not require any removal of contaminated soil and can be done without disturbing buildings and roads. Demolition is simply not necessary. Therefore it’s less expensive and causes fewer nuisances for occupants.
Another advantage is that it leaves no residual contaminations. All the contamination is broken down into hazardless chemicals that will be included in the natural cycle.
In every contaminated situation we work out the most reliable and cost-effective solution.
Together with our clients we determine the best routing possible for a successful soil or groundwater remediation:
