Environmental remediation work is required when Phase II and Phase III environmental evaluation yield contamination levels above those set out by government standards. Remediation allows polluted soil to be brought up to current environmental standards. We start by removing the sources of pollution and implementing control measures to prevent further contamination.
Several factors are taken into consideration when determining the appropriate decontamination method to employ: project costs, the presence of structures and infrastructures, accessibility to the site, time constraints, the size of the site, the amount and type of soil to be decontaminated, the nature of the contaminants and the technologies available.
