Generally the final steps of a mining project are achieving acceptable site closure 
suitable for the anticipated post closure land use.
The OTEK and ARCADIS partnership provides experts that have the experience to assist mining companies to achieve this goal; but regulatory closure may not define the final and best use of the land and water holdings.
We offer our clients practical business solutions for the efficient and cost-effective closure of contaminated sites and forward thinking ideas for post closure land use and sustainability.
Together, the OTEK and ARCADIS partnership are industry leaders in developing innovative mine waste treatment technologies. We use bio-remediation technology that allows for insitu treatment of a wide variety of constituents.
In-situ reactive walls and reactive zones (IRZ) are often used to remediate groundwater beneath and down-gradient from tailings impoundments, waste rock dumps, leach pads or process solution ponds at mines, mills or smelters, or downgradient of pit lakes.
In-situ treatment is also used to avoid a hazardous waste classification by successfully reclassifying wastes.
The application of our mining technologies results in not only cost savings to our mining clients, but also freedom from future remediation responsibilities and regulatory uncertainty.
We provide solutions that save our clients money, reduce environmental liabilities, and that help to successfully obtain closure without lengthy post-closure monitoring requirements.
Once the business plan is in place and the strategy for regulatory closure is laid out, we think to the future for sustainable use of the land and water holdings.
The current business climate as well as the driver for green energy alternatives will prove to be very viable alternatives.
