IS A LINER NEEDED?

Solution[H+] has helped mining companies answer this expensive question as part of several projects.

In South Africa, the National Environmental Management: Waste Act requires a geochemical waste assessment. The results of the analysis dictate the minimum liner requirements. Nevertheless, site-specific risk assessment is often required to obtain a practical and cost-effective solution. 

Geochemical sampling and analysis indicates the defined waste type. Evaluation of the proposed facility, including geochemical modelling of drainage quality and liner performance indicates the potential environmental risk. In one such project, Solution[H+]'s findings indicated that the legislated liner would not materially increase the mitigation of water quality risk. In short, the answer was a resounding NO. This provided the information the Client needed to motivate a facility design without a liner, thus saving millions in capital costs.
