We solve contamination problems. We measure what matters and then design and implement remediation solutions, keeping our clients informed throughout what can sometimes be a challenging process.
Professional services
Most of our services in the field, in court or in the office relate to:
Site contamination audits
- Property redevelopment for residential, recreational and commercial uses
- Waste derived fill audits to facilitate re-use of waste soils, industrial residues + construction and demolition wastes
- Restricted scope audits to comply with EPA regulation
Environmental investigations
- Disposal and/or re-use of waste materials
- Preliminary site investigations (site history)
- Detailed site investigations:
- Soil
- Water (groundwater, surface water)
- Air (soil vapour, indoor and ambient air)
- Asbestos
- Conceptual site models
- Contaminant fate and transport
- Groundwater modelling
- Vapour intrusion modelling
- Site-specific risk assessment
Remediation, management + monitoring
- Soil remediation (disposal, retention, containment, bioremediation, ex-situ vapour extraction)
- Groundwater remediation (skimming, ex-situ pump + treat, in-situ treatments, monitored natural attenuation)
- Soil vapour remediation (soil vapour extraction, vapour barriers)
- Environmental management plans
- Environmental monitoring plans
Other environmental services
- Environmental due diligence for land transactions
- Strategic advice and regulatory liaison
