PFAS

PFAS

Per- and Polyfluoroalkyl Substances

Per- and Polyfluoroalkyl Substances (PFAS) are a group of synthetic chemicals widely used in industrial and consumer products due to their resistance to heat, water, oil, and stains. Commonly referred to as "forever chemicals" because many are highly persistent in the environment, PFAS can contaminate soil, groundwater, and surface water. In contaminated land investigations, PFAS are a significant concern due to their potential impacts on human health, ecosystems, and future land use.

Key Components

• Common Sources: PFAS have historically been used in firefighting foams, industrial processes, non-stick coatings, water-resistant textiles, and other products, with contamination frequently associated with airports, defence facilities, and industrial sites.
• Environmental Persistence: Many PFAS compounds resist natural degradation and can migrate through soil and groundwater, potentially affecting surrounding properties, waterways, and drinking water sources.
• Site Investigation & Testing: Environmental consultants undertake targeted soil, groundwater, and surface water sampling to identify PFAS contamination and assess concentrations against relevant Australian environmental guidelines.
• Risk Assessment & Remediation: Management strategies may include contaminated soil excavation, groundwater treatment, containment, and ongoing monitoring, depending on contamination levels, exposure pathways, and site-specific risks.

PFAS contamination presents significant challenges for property owners, developers, and environmental consultants due to its persistence, mobility, and complex remediation requirements. Early identification and appropriate management are essential to protecting human health, minimising environmental impacts, and supporting regulatory compliance and safe future land use.
