Chlorinated Hydrocarbons – Myths and Realities

Australia has general guidance on vapour intrusion and more specific guidance on assessing vapour intrusion into buildings for petroleum hydrocarbons. However Australian does not have specific guidance for chlorinated hydrocarbons. Most of the guidance for petroleum hydrocarbons also applies to chlorinateds, but it is becoming increasingly clear that there are a range of myths doing the rounds in the industry. This session will help you to understand what the NEPM says about chlorinated hydrocarbons, what the standard approach to assessing risks from vapour intrusion for these chemicals actually involves and what practices need to be avoided.

We will conclude the session with audience driven questions and answers. Please email me at elearning@landandgroundwater.com with any detailed aspects of the subject you would like addressed.

Therese Manning is a principal at Environmental Risk Sciences and a Fellow of ACTRA. She has a long history of undertaking human health and environmental risk assessments as part of the NSW EPA and as a consultant. She provides risk assessment support to a range of government departments and she has been involved in the development of guidance and guidelines for contaminated land assessment.



Dr Jackie Wright is Director of enRiskS, a Fellow of ACTRA and an adjunct lecturer with Flinders University. She has been assessing risks from chlorinated hydrocarbons since the early 1990s. She has prepared national guidance for the NEPM (Schedule B4 and B7) and the CRC CARE Petroleum Vapour Intrusion Guidance and CRC CARE Weathered Petroleums guidance. Her work analysing vapour intrusion data has been included in the USEPA databases. She has been conducting research on characterising exposures and health effects that occur within methamphetamine contaminated properties.
