Site Remediation & Regulatory Compliance
Waste and contaminant characterization and management:Excavation, recovery, and off-site disposal or treatment of impacted soil and/or building materials. Free-phase product recovery, transport and off-site disposal or treatment. Containment, encapsulation, immobilization of contaminated soil and groundwater. Recovery, treatment, discharge and/or recharge of impacted groundwater. In-situ natural attenuation, enhanced bioremediation. Ex-situ biopile and bioreactor design and construction. Soil vapour extraction; soil venting; air sparging.
In some cases, a site specific risk assessment to identify and evaluate exposure pathways and receptors can eliminate the need for costly excavation or other remedial treatment options. This may result in a significant reduction in disruption to the subject property and any on-going or continuing operations, and therefore, significantly decrease overall project costs.
Qualitative Risk Evaluation investigates and evaluates active exposure pathways and human or ecological receptors. Risk to human health and/or the environment, can be defined as the intersection of contaminant, pathway and receptor. If an active exposure pathways (e.g. potable water supply, dermal exposure, etc.), can be limited or eliminated (e.g. alternate water supply, asphalt or concrete seal on the area of impact, etc.), the degree of risk can be reduced or eliminated. Therefore, a qualitative risk assessment may limit or reduce the requirement for disturbance and/or active remediation.
