Odour and Vapour Assessment During Soil Stabilisation Trials on a Hydrocarbon Contaminated Site

Policies aimed at protecting greenfield sites to enhance the urban environment have led to increased prioritization of the redevelopment of brownfield sites. This in turn has led to increased pressure to develop new solutions to deal with the potential nuisance and risks to health and the environment that such redevelopment can bring. As part of the redevelopment of the Auckland waterfront, a trial of both in-situ and ex-situ soil stabilisation techniques has been carried out on land previously used as an oil storage depot. Soils and groundwater beneath the site have been significantly contaminated by petroleum and gasworks derived hydrocarbons. The presence of sensitive receptors nearby and a history of odour complaints for nearby developments have emphasized the importance of assessing odour and the levels of contaminants likely to be observed during the redevelopment work.
