A detailed site investigation involves using the SAP and PSI to collect targeted field data about the nature, distribution and concentration of contaminants to quantify and assess the risks posed to human health and the environment.
This risk assessment attempts to establish remedial standards that define what the Crown must do to meet the requirements of the Deed in regard to contaminated soil. In establishing the remedial standards, the overall objective has been to derive values that are as low as practicable, but no lower than necessary considering these specified future uses. This assessment seeks to recognise Ngāti Maniapoto values, and those of the tangata whenua for Pokuru 1B in particular. Based on engagement with mana whenua to date, the remedial standards should be derived to pose minimal risk to food production, to people who live on the land, and to soil quality, in a rural residential context. In relevant parts of the block, the standards also seek to protect water quality and wetland values including the associated mahinga kai.
