Why Treating Contaminated Land Will Be Different Each Time
Different methods of treating and taking remedial action to clean up contaminated land exist such as isolating and containing the material/substance on site, removing the contaminants away to landfill, introducing other substances which break down the contaminant and either eliminate it altogether or reduce it down to acceptable limits etc. The method(s) employed will need to be the most appropriate and effective according to the contaminants in question, the particular concentration and the intended use/occupants of the site once the remedial work has been carried out.
Because two sites are unlikely to be exactly the same, each one is likely to require a tailored, bespoke approach to the removal and/or treatment of contaminants and pollutants on site in the soil or groundwater which can cause health issues to any living creature on the site. This is why those carrying out the environmental assessments and overseeing the clean-up process need to be appropriately trained and qualified to do so, otherwise not only could they be overlooking and leaving behind a hazard which could endanger a person, but they may even end up making the situation worse. Just as with other areas of health and safety, a little knowledge is often more dangerous than no knowledge at all, as a person who thinks they know what they are doing will attempt it and do an inadequate job, whereas a person who knows that they lack the required knowledge and expertise will bring in a suitably qualified professional for the task.
The safe treatment of contaminated land may also require those carrying out the process to wear suitable protective equipment to keep them from harm, along with frequent monitoring to ensure their exposure to levels of contaminants do not exceed recommended guidelines in terms of the amount and/or length of time.
