We all know the importance of looking after the environment, but sometimes intervention needs to be a bit more drastic than simply remembering to recycle. Environmental remediation is the process of removing contaminants and other harmful materials from the surrounding environment. This can include removal from sediment, soil, groundwater or even surface water. The environmental arm of the Borehole Solutions Group wanted to explain remedial action in a little more detail.
Types Of Environmental Remediation
Remedial action covers a broad range of different processes, including the following:
Amongst the simplest remedial techniques is excavation, a soil remediation technique. A lot of the time, no fancy chemicals or solutions are required, just a good old-fashioned digger taking contaminated material to landfill. It can, of course, be more complex than that and involve aeration and oxidation processes if necessary.
Determining what landfill excavated waste is suitable for is another topic in its own right. We’ve previously looked at Waste Acceptance Criteria (WAC) testing in a piece which you can find, here! If the affected/contaminated material is within a riverbed’s silt, then dredging is used as a marine alternative to excavation.
Pump & Treat
Pump and treat is a well-established groundwater remedial technique, though not the most common given its relative slowness and the expense of treating the contaminants. The process itself, as the name might suggest, involves pumping out contaminated groundwater which can then be subsequently treated or safely disposed of.
Bioremediation is one of the most complex and interesting remedial techniques, though it’s not all that common because of this. Not only that but lack of implemented policy frameworks means it can be difficult to implement even when it would be beneficial. The process involves using the growth of microorganisms (hence bio) as a means of then degrading the contaminants and pollutants.
SEAR – Surfactant Enhanced Aquifer Remediation
‘SEAR’ offers an effective alternative (or perhaps more accurately, enhancement) to conventional pump and treat remediation techniques. The injection of a surfactant solution into the contaminated zone – the surfactant molecules able to dissolve the typically insoluble contaminants within groundwater – offers an effective way of quickly removing contaminated material from an area.
Removal Of Asbestos
Asbestos testing and removal is one of the most common forms of contamination testing, mainly because of just how common asbestos was as a construction material until the UK chrysotile asbestos ban back in 1999. Asbestos is a known carcinogen (causes cancer) and so it must always be dealt with safely and legally by qualified contractors.
