Guidelines for assessing and managing contaminated gasworks sites in New Zealand

Publication date:  August 1997
Publication reference number:  ME 244

The Users’ Guide includes information on assessment, acceptance criteria and site management. It is supported by modules of technical information.

Please note that the soil acceptance criteria for Benzo(a)pyrene (BaP) are superseded by the soil contaminant standards under the National Environmental Standard for Assessing and Managing Contaminants in Soil to Protect Human Health (NES).

The other generic health-based ‘soil acceptance criteria’ used in these guidelines are not derived according to the methodology referenced in the NES. However, while there are no specific soil contaminant standards relating to these contaminants of concern yet, the ‘soil acceptance criteria’ developed in these guidelines are likely to be the most appropriate to select as applicable standard  because they are risk-based and developed for New Zealand circumstances.
