Further information

Who assesses a site for contamination?

When underground storage tanks are removed from a site, an investigation must be carried out to determine whether contamination has occurred, and an investigation report provided to Environment Canterbury. It is best to engage an environmental consultant with proven experience in assessing contamination from tank removals to ensure the investigation is able to comply with the requirements of proposed Regional Rule.

What are contamination risk factors?

Sites can release hazardous substances beyond the immediate area of contamination and into the environment through:

stormwater infiltration through runoff or soakage in soak pits
leaching into ground water
volatilisation (where the hazardous substance vaporises, with the potential to accumulate in certain structures
loss to air, for example by evaporation or being transported on fine particles (wind blown dust).

The site itself can also present risks to the environment because:

contamination in soil can be taken up by plants that are consumed by humans, livestock or other animals
contaminants in the soil or sediment may present a risk to those in direct contact (through skin absorption, inhalation or ingestion routes of exposure)
Specific flora and fauna or certain ecosystems may not be able to establish or survive because of the levels of contamination in soil or sediment.
