Contaminated Groundwater and Vapour Intrusion Mitigation Design
Project: Contaminated Groundwater and Vapour Intrusion Mitigation Design
Year Completed: 2019
Groundwater Impact and Ingress Assessment, Basement Waterproofing Design, Vapour Intrusion Mitigation Design
EPG provided advice regarding the design and installation of a contaminated groundwater and vapour intrusion mitigation system, where both elevated soil vapour and petroleum hydrocarbon-impacted groundwater intersected a proposed high-density residential basement development in New South Wales.
EPG’s remit was to provide the client with design and mitigation options, while taking into consideration the unique basement structure and survivability concerns regarding the geomembrane(s) in contact with contaminated groundwater. The design involved the assessment of a range of geomembrane products and structural barriers. EPG were able to provide a range of options which were defensible both from a human health protection perspective and basement integration and durability perspective, whilst allowing the client and builder to select the preferred solution.
