Management of Contaminated Sites

We provide full-cycle remediation solutions for contaminated land, ensuring safe reuse and environmental recovery. We begin with Environmental Site Assessments (ESA) to evaluate pollution risks, followed by detailed remediation planning tailored to site-specific contaminants. Our methods include In-Situ Chemical Oxidation (ISCO), which injects oxidants into polluted zones to break down hydrocarbons and solvents without excavation, and Ex-Situ Soil Remediation using thermal desorption, soil washing, or bioremediation off-site. AI-supported monitoring enhances precision and process efficiency. From brownfields to industrial legacy sites, we deliver cost-effective, regulatory-compliant outcomes with proven ecological and community benefits.
