Environmental Site Remediation
Coffey Environments uses a scientific, step-by-step approach to environmental site assessments and the design and implementation of remedial strategies. This approach provides customers with the flexibility to customise solutions to a specified risk level.
The main steps are assessment, remediation, monitoring and closure. Assessment is used to develop a focused remediation plan when needed.
Our speciality is the design and implementation of site remediation systems. Establishing practicable remediation targets with all stakeholders is critical for maximising project value for site owners, ensuring remedial goals are reached cost-effectively.
Typical remediation methods include:
- engineered - sound barricading, dust filters and suppression devices, changes to management practices, planning constraints
- chemical - catalytic, chemical, and advanced oxidation, pH adjustment and precipitation, chemical fixation, sequestering, chelation, and dispersion
- physical - pumping for recovery of resources, soil venting, air sparging, air stripping, carbon adsorption, multi-media filtration, thermal desorption, reverse osmosis or ultra-filtration
- biological - END™ enhanced natural biodegradation systems for in situ bio-remediation, in-vessel bio-reactors, aboveground treatment cells, in situ bio-stabilisation, land farming and composting, treatability, feasibility and pilot studies
- thermal - “Soil Roasting”, indirect thermal desorption, base catalysed dechlorination, steam injection and other treatment forms.
