Some contaminants break down in the soil very slowly, while some don’t break down at all, so they may be present on a site for a very long time.

 

Contaminants can leach into waterways.

Contamination in soil can be taken up by plants that are consumed by humans, livestock or other animals.

 

Some contaminants which pass through the food chain concentrate in the tissues of fish, birds, livestock or humans.

Contaminants in the soil or sediment may present a risk to those in direct contact (through skin absorption, inhalation or ingestion).

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
