All containers remaining temporarily on-site, and containing potentially contaminated materials, should be labelled with appropriate hazard warnings and waste producer contact details.

    15.2.6      Collection and disposal of excavation spoil
It is normal practice to return excavation spoil from test pits to the excavation from which it came. However, care should be taken to ensure that materials are replaced in soil horizon order and that contaminated materials are not returned to a pit where they could contaminate unaffected strata or groundwater. Due to practical difficulties in compaction of excavation spoil there will inevitably be excess spoil after backfilling of a test pit. Care should be taken to ensure that contaminated spoil does not become spread across an otherwise uncontaminated surface. Drilling cuttings should not be returned to a bore.

Excess spoil should be stored in a lined skip or lined drums brought to site or placed on an impermeable surface such as concrete, asphalt, polyethylene sheeting or similar until analytical results can be assessed to enable cost-effective and safe methods of disposal. Where excess spoil is stored on site, and is not stored within a container, bunding should occur around the area to contain potential run-off. If contaminated materials are to be drummed for disposal or for treatment, the contents should be analysed, and management decisions made, based on the analytical results. All containers remaining temporarily on-site, and containing potentially contaminated materials, should be labelled with appropriate hazard warnings and waste producer contact details.

Allowances should be made within site assessment budgets for any necessary safe removal of a quantity of soil/fill from the site to an appropriate waste disposal or treatment facility. Transport and disposal of contaminated soil should be carried out in accordance with relevant state or territory legislation.

    15.2.7      Noise and vibration
Noise can be a health risk to workers and is often a nuisance to those in the vicinity of a site. The potential for noise arising from site assessment activities should be evaluated and appropriate control measures put in place to reduce unacceptable noise (for example, by installing screens or noise baffles). Noise should not be a nuisance to people living or working around the site. Activities with potential for noise generation should be carried out in accordance with relevant state or territory legislation.

Similarly, vibration from excavation and drilling, from plant, or from the movement of heavily laden trucks can sometimes result in damage to foundations of adjacent structures or to underground services or utilities. This possibility should be addressed and any risks assessed prior to choice of excavation or drilling method.

    15.2.8      Acid sulfate soil
Acid sulfate soils (ASS) are naturally occurring soils, sediments and peats which contain iron sulfides. In an anoxic
