Risk Assessment and Remediation

The former Wollongong gasworks operated over the period between 1880s and late-1970s, leaving a legacy of gasworks wastes that have gradually been cleaned up in the years since. Senversa conducted soil, soil vapour, groundwater and surface water investigations, and remediation feasibility studies, in order to develop a remedial approach for the remaining portion of the former gasworks site. Senversa completed a human-health and ecological risk assessment, resulting in the development of site-specific threshold levels. These works helped Senversa develop a pragmatic risk-based remediation strategy documented in a Remedial Action Plan that aims to mitigate the client’s environmental liabilities and restore the site so it can be put to more productive use. Senversa is currently engaged as the validation consultant.
