QDS is a complete remediation service provider, driving a project all the way from initial Quantitative Risk Assessment, through the remediation process, to regulatory sign off. This process may include:

• Quantitative Risk Assessment
• Feasibility testing
• Remediation
• Regulator liaison and negotiation

QDS employs a range of technical specialists including engineers, hydrogeologists, geologists and chemists organised into project teams. Each team is headed by a Project Manager who integrates the different disciplines to achieve efficient project delivery.

A provider of a comprehensive range of remediation solutions on over 360 projects, QDS has successfully pioneered the full scale, real site application of three technologies in UK: In-situ Chemical Oxidation, Ammonium Ion Exchange and DNAPL Flow Path Management.

In recent years, QDS has further improved cost effectiveness by successfully containerising multi-phase integrated remediation systems combining different technologies to treat complex contaminant profiles.
