Soil Vapour Assessment

Soil vapour assessment is the investigation of volatile contaminants (i.e. substances that easily evaporated at normal temperatures) present in soils, that pose a risk to human health when inhaled. Volatile contaminants such as petroleum hydrocarbons and chlorinated solvents may be released to the subsurface environment through accidental spills, leaking of underground tanks and unregulated burial […]

Perfluorinated Chemicals (PFCs) – A Contaminant of Emerging Concern

PFCs are now emerging as a contaminant of concern in soils. PFCs are broadly distributed and persistent in the environment and the vast majority of living people from industrialised nations have detectable concentrations of PFCs in their blood. Elevated levels of PFCs in blood have been linked to a number of health effects. These range […]

Contaminated Land – An Introduction

Common Causes of Contaminated Land Contaminated land, at its most basic level, refers to the degradation of land surfaces as a result of human activities. As a result, the area is affected by hazardous substances (e.g. arsenic, DDT or oil) which may pose a risk to human health and/or the environment. While contaminated land can […]

Barangaroo Blaze Causes Hazardous Materials Fears to Reignite

The outbreak of a raging fire in the basement of a section of the Barangaroo construction site has reignited concerns about the presence of high levels of hazardous materials at the site. While the blaze has been brought under control overnight, discussions have re-emerged over site contamination. From the mid 1820s, the previously named East […]

How Healthy is your Soil? – The Dangers of Acid Sulphate Soils

What are Acid Sulphate Soils? Acid sulphate soils are a mix of low-lying coastal clays and sands that contain sulfur bearing compounds at concentrations above 0.05% in clays and 0.01% in sands. Such soils are formed as naturally occurring sediments are deposited under estuarine conditions. Thus, the distribution of these soils commonly reflects the past […]
