GeoStream as your single source provider is not stuck to one technology or approach, and will assess each site on its own merits. Where chemical technologies are the chosen solution, we offer a portfolio of field and regulatory proven, sustainable technologies that deliver groundwater and soil remediation for both in-situ and ex-situ applications. Our specialist team of design staff work alongside your project team ensuring our solutions offer maximum efficiency, cost effectiveness and most importantly are acceptable to regulators.
Our process based plant, chemical oxidation and bioremediation technologies provide a fully integrated solution for your site, ensuring rapid, cost-effective treatment of a wide range of organic compounds and heavy metals.
The illustration below provides the cost value basis for technology selection.
We have a selection of chemical technologies exclusively available which are tried, tested and approved by regulators to deal with all contaminants typically encountered. Provided below is a summary table with more detailed technical information on individual solutions.
The innovative Trap & Treat® BOS 100® and BOS 200® products offer environmentally-friendly solutions for soil and groundwater contamination. BOS 100® ‘traps’ chlorinated solvent contaminants, then treats them with a safe, effective reductive dechlorination process. BOS 200® breaks down contamination with a specially formulated blend of activated carbon, sulphate reduction media, micronutrients and facultative microbes.
In-situ chemical oxidation (ISCO) involves the injection or direct mixing of reactive chemical oxidants into groundwater and soil for the primary purpose of rapid and complete contaminant destruction.
Chemical technologies available include sodium and potassium permanganate, sodium persulphate and hydrogen peroxide.
Bioremediation refers to the degradation of organic contaminants in soil or groundwater by indigenous or transplanted/acclimated microorganisms. Environmental conditions can be altered by the addition of electron acceptors/donors to support and enhance the rate of bioremediation. Bioremediation is used to target both in-situ and ex-situ contamination in both soil and groundwater.
Biological treatment technologies available include:
