QDS is a very professional company to work with. They remediated a difficult site with great skill to a high standard, on time and on budget and I would not hesitate to use them again or recommend to others.
Pilot Trials and Bench Testing
Every brownfield site is different, and complex contaminant profiles in variable geologies can make remediation design uncertain. Pilot trials and bench testing form an essential part of many projects and provide the necessary technical design certainty.
We have an in-house laboratory where many of the technologies we apply have been developed for full scale application. We undertake bench testing of remediation methods on-site specific soils & groundwater – both to support decision making and optimise remedial design. This form of forensic work places us at the cutting-edge of our industry. It informs our research and development of new technologies to mitigate legacy contamination issues that ultimately helps unlock complex sites for future development and community benefit.
We undertake a range of studies for the evaluation of:
- In-situ bioremediation
- Chemical oxidation
- Stabilisation / solidification
- Thermal recovery methodologies
- Surfactant flushing
Our wide range of plant includes pilot testing equipment to provide site specific data and confirm remedial design in advance of full scale application, reducing risk for our clients. Our bespoke trailer mounted pilot trial plant includes water and vapour effluent treatment and may be quickly deployed for the assessment of:
- Hydrogeological testing and groundwater abstraction rates
- NAPL recovery tests
- Sparge trials and vacuum radius of influence
- Reagent injection testing
