Contamination is a potential threat to the value of your property and any potential purchaser in Australia of property should have a Preliminary Site Investigation (Contamination Assessment) undertaken prior to purchase. Generally Australia has somewhat lagged behind areas like North America in the Due Diligence assessment prior to purchase of real estate. The recent articles in the Sydney Morning Herald indicate to the public how widespread contamination can be and its potential impacts to properties hundreds of metres from the point of contamination. The potential for human health impacts can be high due to dangerous chemicals in the soil or watertable from direct contact or vapour intrusion into residential buildings. We at Anderson Environmental Pty Ltd recommend a thorough assessment of the potential of contamination before a property is purchased as the potential clean up and health costs are high.
