Our risk team uses qualitative and quantitative risk assessment techniques to assess risks to human health and the environment. This includes identifying and assessing the risk of harm as required for statutory environmental audits.
We always take a pragmatic approach to limit the level of assessment to that which is required to inform decision making. Our team are strong advocates skilled in liaising with key stakeholders (including auditors and regulators) to efficiently close out site issues.
Our risk assessment specialists are active members of both Australian and international professional organisations, ensuring current and best practice approaches to the assessment and management of risk, be it vapour intrusion assessment, groundwater transport modelling, chemical toxicity assessment or overall risk management and mitigation measures.
Above all, we place emphasis on risk based solutions and the considered use of risk assessment with respect to overall site management objectives.
Human Health Risk Assessment
Vapour Intrusion and Exposure Assessments
Ecological Risk Assessment
Groundwater Contaminant Risk Assessment
Landfill Gas Risk Assessment
Senversa was engaged to complete a comprehensive PFAS investigation (Per- and Poly-fluoroalkyl substances) as well as a human health and ecological risk assessment at the RAAF Base East Sale, Victoria. This project was conducted in a complex hydrogeological and surface water receiving environment and within a rapidly evolving understanding of PFAS toxicity. The area under investigation included the base as well as privately owned agricultural land, public waterways and a nearby wetland. Senversa applied a highly-skilled multidisciplinary team of contaminated land specialists, risk assessors, hydrogeologists, ecologists, and community consultation experts to undertake this project.
Senversa prepared a Remedial Action Plan for the former Wollongong gasworks including an assessment of soil, groundwater, surface water and vapour to identify gaps in previous data and develop an informed and robust plan. Senversa also completed a human health and ecological risk assessment resulting in the development of human health site-specific, risk-based trigger levels and a qualitative assessment of ecological receptors. Senversa also supervised the remediation of waste and validation of the site surface following completion of the remedial works (on a portion of the site), as well as a detailed vapour assessment of the remaining material. This enabled the development of a remedial plan that would allow development consent to be applied for so that the site could be brought back to productive use.
Ash Residue from Mine Fires, Vic
As a result of the Hazelwood mine fire in 2014 which burned for 45 days, Senversa was engaged to conduct a series of investigations to assess levels of residual brown coal ash in roof cavities of residences in the Morwell area and surrounds. This included community and stakeholder communications regarding the likelihood of any ongoing health risks to residents exposed to ash residue.
