Environmental Earth Sciences International was engaged to design a remediation technique to maximise the onsite reuse of soil after metal contamination in soils had occurred.
THE SOLUTION
To address this challenge, the EESI team developed a technique to immobilise metals such as lead and mercury in soil through the formation of non–soluble mineral complexes. To demonstrate the effectiveness of the technique, a Mobile Unit for Soil Treatment was deployed at a field site to treat a total of 4,000m³ of contaminated soil.
THE BENEFITS
The process was successfully undertaken at field scale, which led to substantial cost savings.
A new remediation technique with outstanding results, this case study highlights EESI’s ability to develop innovative remediation techniques that can be used to mitigate the associated environmental and health impacts of complex metal contamination in soils at a field scale.
