This guideline has been developed through a partnership between the Ministry of the Environment, and regional councils and unitary authorities to ensure the consistent selection and application of the environmental guideline values most commonly used in contaminated site assessments in New Zealand. The principles and basis for a hierarchy of environmental guideline values as contained in reference documents is described and the hierarchy established. This hierarchy determines the order in which guideline values contained in those reference documents should be used in a contaminated site assessment. It will be of use to environmental consultants and landowners undertaking contaminated site investigations, and to council staff involved in reviewing contaminated site assessment reports.
