Risk Assessment of Petroleum Hydrocarbons in Groundwater

2012 Summer Workshops

Date:

Venue:

Petroleum hydrocarbons are hazardous substances under the Groundwater Regulations and one of most the most common and problematic contaminants impacting groundwater resources. The workshop aims were to:

  • Give the background on analytical and forensic methodologies for petroleum hydrocarbons and discuss how to take the most appropriate samples in site investigation;
  • Examine the key issues in risk assessment modelling and vapour risk assessment; and
  • Present developments in policy covering Groundwater Regulations, Part 2a and ongoing initiatives. The workshop followed the same format as previous SoBRA summer workshops with thought-provoking presentations in the morning followed by an afternoon of break-out session discussion groups.
