Dealing with emerging contaminants

Back to highlights summary

Over the past year, a key focus for EPA has been understanding the extent and characteristics of emerging contaminants in the Victorian environment.

There are many chemicals in common use which find their way into the environment and are considered contaminants of emerging concern, such as pesticides, pharmaceuticals and personal care products.

Emerging contaminants are a key focus because the risk they pose to our health and the environment is not yet fully understood. To help address the broad range of contaminants in the environment, EPA has undertaken sampling of fresh and marine waters, sediment and soils at 50 sites across the state. This ambient assessment program will provide evidence to inform regulatory actions for emerging contaminants based on our understanding of their presence in the Victorian environment and thus potential for community exposure.

EPA has also continued to lead the way in the prevention and management of environmental and human health impacts associated with a particular group of manufactured chemicals known as PFAS. Used for decades in a range of products, including pesticides, stain repellents and firefighting foams, PFAS are of concern to the environment and human health because they persist in the environment and are resistant to normal environmental breakdowns.

During August and September 2017, EPA Victoria, under the direction of the Heads of EPAs Australia and New Zealand (HEPA), led an extensive consultation process to assist with the development of a PFAS National Environmental Management Plan (NEMP). Calls for feedback from industry and the community resulted in more than 180 responses, including more than 80 submissions.

Now finalised, the NEMP represents a how-to guide for the investigation and management of PFAS contamination and provides Australia with a consistent, practical, risk-based framework for the environmental regulation of PFAS contaminated materials and sites. It describes PFAS compounds and their many sources, requirements for the management of contaminated sites, how best to manage PFAS-contaminated waste (including contaminated soils) and summarises treatment technologies that may be available in Australia.

Future work and research activities around PFAS will feature the study of PFAS precursors and behaviours, the development of Australian guidelines for wildlife food and water quality, considering multigenerational effects, and understanding PFAS sediment concentrations on aquatic biota.

EPA’s leadership role in the development of the NEMP is an example of us taking active steps to prevent and manage the environmental and human health impacts associated with emerging contaminants and working together with government, industry and community stakeholders on a national scale.

PFAS National Management Plan

EPA led an extensive consultation process to assist with the development of the National Management Plan.

Over 180 responses were received, including more than 80 submissions.

The plan provides Australia’s state and territory governments with a consistent, practical, risk-based framework for the environmental regulation of PFAS-contamined materials and sites.

PFAS accumulate in the bodies of animals and concentrations can increase significantly in the tissues of animals higher up in the food chain.

PFAS accumulate in the bodies of animals, particularly those that breathe air and consume fish, and concentrations increase significantly in the tissues of animals higher up in food chains.

EPA is committed to conducting further investigations to better understand the risks of exposure to PFAS. With the support of EPA’s Chief Environmental Scientist, EPA is leading work to better understand PFAS, in addition to other emerging contaminants of concern.
