Naturally Occurring Asbestos

Naturally Occurring Asbestos (NOA) refers to the asbestos mineral in its natural form as a component of soils or rocks.

Less than one percent of land in NSW is believed to contain NOA within 10 metres of the ground’s surface. NOA veins are scattered around the state, mostly west of the Great Dividing Range.

Only testing by a National Association of Testing Authorities accredited laboratory can confirm the presence of NOA in the environment.

Any work or activities that could disturb affected earth, rocks, and soils creates a potential risk. This is because disturbing NOA can release asbestos fibres into the air, which could be inhaled or contaminate clothing and equipment.
