Predicting Petroleum: How Do Models Measure Up?

You’ve got an exceedance of a Health Screening Level -  uh oh!  But is there a risk?  How do you tell?  And how accurate are risk assessment models anyway?  Join us for an introduction to petroleum vapour risk where we have a look at some of the assumptions behind the HSLs, what information you’ll need to provide for your risk assessor, and some research into the difference using site-specific inputs makes with modelling and how closely modelled concentrations match measured indoor air concentrations.


Sheridan Chapman is a risk assessor with 10 years’ experience in the contaminated land industry, assessing everything from wet basement vapour scenarios to how copper affects frogs.  She has recently completed her Masters of Occupational Hygiene and Toxicology, where her research project focused on vapour intrusion models and comparison of modelled vs. measured concentrations.
