Contaminant assessment and site remediation
Contaminant assessment and site remediation projects generally begin with site reconnaissance and scoping, and are followed by subsurface investigations. These investigations are designed to define the physical characteristics of the subsurface and to estimate the magnitude and distribution of contaminants in soil, sediments or water.
This information is then used to determine if risk assessment, further investigation, feasibility studies or remediation is necessary.
AMEC’s experienced professionals provide environmental site assessment services to define the historical use of properties,and to identify current or historical "high risk " features. These assessments often precede formal Remediation Investigation / Feasibility Study Investigations or Phase I Site Assessments, and are designed to determine if past or potential contaminant releases may constitute a threat to human or ecological receptors.
Should remedial activities be desired or necessary, feasibility studies may follow. AMEC is experienced with tests including aquifer stress, soil-air permeability, and in-situ sparging and groundwater treatability. Testing is carried out so that a broad range of remedial options can be identified and evaluated. A number of factors are examined as part of the evaluation process. These include technical feasibility, cost-effectiveness, and protection to human health and the environment. The remedial selection process often has to satisfy a number of conditions, including the cleanup standards set by the regulators, the financial resources of the owner or responsible party,and the needs of the local community.
When remediation is necessary,a comparative assessment of remedial alternatives is undertaken to select the most appropriate technology.
The assessment of alternatives typically includes:
- Cost-Benefit Analyses
- Development of Cleanup Schedules
- Ratings of Health and Safety Issues
- Evaluations of Requirements for Future Activities
AMEC develops integrated remedial solutions that incorporate innovative technologies designed to address complex contamination problems.
Technologies can be initially tested on a bench scale using AMEC’s in-house laboratory facilities. This is especially beneficial for assessing the feasibility of bioremediation and to provide the necessary design criteria for full- scale remediation systems.
