Our specialist teams of environmental scientists and engineers at Rowan are vastly experienced in environmental due diligence assessments (Phase I and II), land contamination assessments and waste classification. We develop tailored, site-specific Conceptual Site Models and related Risk Assessment Models to evaluate the potential environmental risks associated with specific operations. We have completed over 400 EDD assessments on behalf of both vendors and procurers in the petroleum industry, food industry, energy sector, local authorities, IT sector and manufacturing as well as investors, receivers, insurance companies and loss adjusters.

Environmental Due Diligence

Environmental due diligence (EDD) is the process of evaluating the potential environmental liabilities of acquiring or selling a business or property. By identifying potential environmental risks and liabilities associated with a property or business acquisition, steps can be taken to mitigate these risks, avoid costly litigation or regulatory violations and demonstrate commitment to responsible business practices.

In order to determine the potential for environmental liabilities associated with soil or groundwater contamination, a Phase I Site Investigation is carried out. This is a comprehensive review of available data to determine potential sources, pathways and receptors of contamination.

A Phase I Site Investigation, typically includes:

  • Verification of the current and historic land uses of the site and the surrounding area.
  • Appraisal of environmental databases, permits or licences of the site, with a view to determine historic contamination and site sensitivity to contamination.
  • Consultation with regulators, such as the EPA and local councils.
  • Site walkover survey to identify potential hazards and receptors on the ground.
  • Identification of potential environmental risks and reporting of same.

If the Phase I assessment finds that sufficient residual risk remains, a Phase II survey may be initiated which typically includes:

  • Full supervision of Phase II site monitoring, such as ground and water sampling.
  • Laboratory analysis of samples.
  • Evaluation of the findings of Phase II site monitoring.
  • Recommendations for site remediation, if necessary.

Contaminated Land Assessment & Management

Our specialist team complete site-specific assessments of potentially contaminated land to determine the best management and remediation solution for our clients. We have developed tailored, site-specific Conceptual Site Models (CSM) and related Risk Assessment Models to evaluate the potential environmental risks associated with contamination events, and after careful analysis of the CSMs, we can develop cost-effective and appropriate solutions based on scientific evidence. Delivering successful remediation projects is a balance between using the most effective technologies and methodologies, while mitigating the risks and costs involved to the responsible parties.

Rowan use the most appropriate international/national criteria in setting targets for the remediation project, whether they are in terms of air quality, groundwater quality, soil quality, surface water quality or risk indices (human health or environmental). We can provide all the expertise in-house to undertake the sampling and analysis of all environmental media, and report those results in terms of the agreed significance criteria (for the project).
