Environmental consciousness is now more important than ever to preserve our planet for years to come. More and more people are recycling or switching to renewable energy sources; but sometimes, more extreme interventions are necessary. One such method is environmental remediation. Let’s explore what the remediation process involves and the various methods that can be used.
What is Environmental Remediation?
Despite government regulations, many industries still contribute to environmental degradation. This could be in the form of accidentally releasing hazardous by-products from production processes, but organisations are still legally required to address it.
Remediation is the process used to contain and safely dispose of any contaminants within the environment. A polluted site poses significant risk to human health as well as damage to the eco-system, hence environmental remediation is essential.
Geotechnical Site Investigation
Prior to any remediation work, a geotechnical site investigation must be carried out. This involves assessing the site and mapping out the area to determine where contaminants would most likely be present. Following this, site investigation techniques can be used to retrieve samples for laboratory testing and identify the best method for disposal.

Environmental Remediation Processes
A wide range of processes are covered by remediation action, including:
This is the most common form of remediation that we offer at Borehole Solutions. Excavation is often straightforward – a digger is used to transport contaminated soil to a suitable landfill site. However, sometimes the process can involve oxidation and aeration. If the material is surrounded by water, then the marine equivalent is required: dredging.
This is one of the most complex remediation methods and it has few policy frameworks to follow, meaning it can be a struggle to implement for any construction project. Bioremediation involves growing microorganisms to break down the contaminants in the environment.
Pump and Treat
Pump and treat is exactly what it says on the tin! The process involves pumping out the groundwater for treatment or disposal. Although it’s not a common remediation technique due to its slow speed and the cost of treatment, it’s very well-established amongst the industry.
Surfactant Enhanced Aquifer Remediation (SEAR)
This method can be used alongside the pump and treat method described above. It involves injecting surfactant into the contaminated area to dissolve any insoluble pollutants within the groundwater. SEAR is known to be one of the quickest and most effective cleansing methods available.
Asbestos became a forbidden construction material in 1999 as part of the UK chrysotile asbestos ban. It’s common practice to test sites for its presence to meet health and safety standards. However, it must be carefully removed by a qualified contractor as it’s a known carcinogen.
