ACLCA Member Presentation - Tuesday 10 November 2020

One fish, two fish... A refresher on the derivation and application of ANZG (2018) toxicant DGVs

The November Monthly Member Presentation is presented to you by ACLCA Victoria’s Risk Assessment Focus Area (RA FA) and focuses on the derivation and application of the default guideline values (DGV) for toxicants in fresh water and marine aquatic ecosystems from ANZG (2018). 

The ANZG (2018) Water Quality Guidelines supersede the ANZECC and ARMCANZ (2000) Guidelines, but what has changed for contaminated land professionals?

Clare will give an overview of the methodology used to derive DGVs, including some of the changes compared to the trigger values from ANZECC and ARMCANZ (2000).  Kristi will then discuss how the DGVs are selected and applied in the contaminated land sector, in particular in the context of the Victorian SEPP (Waters of Victoria).


Clare Papaleo is an Environmental Scientist specialising in ecological risk assessment at Golder. Her five years in the contaminated land industry has seen her work on ecological risk assessments across most of Australia, as well as assessments of plant protective products, veterinary medicines and biological control agents for the Australian Pesticide and Veterinary Medicine Authority (APVMA). Clare also provides broader support to Golders’ contaminated land team with a particular interest in precinct wide site prioritisation projects. On the weekends she can usually be found in her garden, or in parkland getting overly excited by plants and frog calls.

Kristi Hanson is a Principal Risk Assessor and Victorian Environmental Auditor at Senversa, with more years of experience than she would like to let on, and has completed hundreds of human health and ecological risk assessments within Australia and overseas. Kristi enjoys developing new models and approaches to refine the risk assessment process and efficiently manage contamination issues at a site. Outside the office, Kristi has spent the lockdown period walking every street in her and neighbouring suburbs, trying to play the guitar, and starting a lot of craft activities (some of them are even finished!).
