Risk Characterisation

One of the key outcomes of this site was to provide New Zealand-specific data for risk assessment.

New Zealand Ecotoxicity Test Protocols

Various tests and protocols have been developed for determining ecotoxicity levels in both aquatic and terrestrial flora and fauna, as well as determining the mobility of various contaminants through soil and water.

New Zealand Ecotoxicity Test Results

New Zealand ecotoxicity test results for copper, chromium, and arsenic are presented. Please observe the copyright provisions if you intend to use this data:  

Note that a listing of ecotoxicity data for CCA and BTEX from the international literature can be found here.

Contaminant Mobility Tests & Results

Contaminants on or in soils may move into the wider environment through a number of routes. The soils themselves retain contaminants to a greater or lesser extent. The movement of contaminants from soil occurs through evaporation and dust generation, intake by plants through their roots, and flushing by or dissolution into water seeping through the soil. 

Contaminant mobility in New Zealand was studied, and two reports are available. Part 1 concerns mobility in the subsoil. Part 2 is an assessment of the relevance of specific hydrogeological factors on groundwater contamination. The latter has been implemented as a model.

Soil Property data

A table of various soil properties that can be used in the groundwater site risk assessment tool and for other purposes (coming by June 2004).

New Zealand Water Environment Research Foundation

A not-for-profit organisation aimed at providing national independent management of research in science, engineering and management practices in the fields of water, wastewater, stormwater and waste. Its purpose is to provide national co-ordination of research activities in New Zealand's water environment and provide the means to facilitate and broker research activities between research users, funders and providers. This includes raising funding and commissioning projects for research projects with national priority.


The New Zealand Stormwater Directory

The purpose of the directory is to assist those involved in stormwater management locate stormwater information specific to their requirements. The site contains a database of stormwater management publications, some of which will be useful in developing catchment and stormwater management plans under the Resource Management Act and Local Government Act. Other resources will be useful in the processing of resource consent applications, managing stormwater quantity and quality issues, managing existing stormwater infrastructure more effectively and designing sustainable stormwater systems.
