IntroductionThis section of the site is principally a collection of tools and resources for assessors undertaking Tier 2 and Tier 3 assessments, researchers, and government agencies (e.g. ERMA). Limited numbers of practitioners or regulatory staff in New Zealand undertake, audit or review Tier 2 assessments using models, and refining guideline values to site-specific conditions and contaminant characteristics. However, as regulatory agencies are becoming more familiar with the risk assessment process, they are tending to require higher levels of justification for risk management decisions, particularly in urban areas. As a result, it is considered that there will be an increasing need for Tier 2 assessments in New Zealand. There are only a handful of sites in New Zealand that will require a Tier 3 assessment. "Advanced risk assessment" provides detailed information on the models best suited to New Zealand conditions, contaminant characteristics, and international resources. In addition, detailed research into contaminant behaviour in the New Zealand environment and ecotoxicology of New Zealand native and naturalised species is presented.

The methodology is broadly based on Australia's National Environment Protection (Assessment of Site Contamination) Measure (NEPM) 1999. |
