Chemical treatment of contaminated soil and groundwater
Chemical treatment of contaminated soil and groundwater is usually aimed at either destroying contaminants or converting them to less environmentally damaging forms. In-situ chemical oxidation (ISCO) involves injection of chemical oxidants into the ground and has the potential to effectively treat a wide range of organic contaminants. ISCO treatment tends to be more rapid than some other forms of treatment, such as in-situ bioremediation.
Chemical treatment is sometimes used for the treatment of pumped groundwater or landfill leachate. Typically, these treatments are aimed at removing or immobilising contaminants, or changing the physico-chemical condition of the water.
Chemical treatment applications
Some of our previous chemical treatment projects had the following objectives:
- Chemical oxidation of organic contamination in soil, groundwater and landfill leachate.
- Neutralisation of acid or alkaline effluents.
- Removal of metallic species from wastewater by pH adjustment and settlement / flocculation.
- Flocculation of suspended solids.
Telluric Land Remediation has many years of experience in the use of chemical treatments for soil, groundwater and leachate. We will make a full assessment of your contamination problems and, where appropriate, design and implement a chemical treatment strategy fully optimised for your site.
