Product Overview

Summary: This Contaminated Soil Management Safe Operating Procedure sets out clear, practical steps for safely identifying, handling, storing, transporting and disposing of contaminated soils on Australian worksites. It helps organisations control worker exposure, prevent environmental harm, and demonstrate compliance with WHS and environmental legislation across construction, infrastructure, remediation and civil projects.

Contaminated soil is a common and often underestimated risk on Australian construction, civil and maintenance projects. Legacy industrial activities, underground storage tanks, asbestos, PFAS, hydrocarbons, heavy metals and other pollutants can create serious health, environmental and regulatory issues if disturbed without a clear, documented process. This Contaminated Soil Management SOP provides a structured, end‑to‑end approach to identifying potential contamination, assessing risks, and implementing robust controls before, during and after excavation or soil disturbance activities.

The procedure is designed to help businesses meet their duties under WHS and environmental law by standardising how contaminated soil is classified, segregated, stockpiled, sampled, transported and disposed of. It clarifies roles and responsibilities between site management, contractors and consultants, and integrates practical controls such as exclusion zones, dust suppression, PPE, decontamination and incident response. By adopting this SOP, organisations can minimise worker exposure, reduce the likelihood of environmental incidents, avoid costly project delays and demonstrate due diligence to regulators, clients and the community.

Key Benefits

• Ensure consistent, compliant management of contaminated soil across all projects and contractors.
• Reduce worker exposure to hazardous substances such as asbestos, hydrocarbons, PFAS and heavy metals.
• Minimise the risk of environmental harm, regulatory breaches, fines and stop‑work notices.
• Streamline communication between project managers, WHS teams, environmental consultants and transport/disposal providers.
• Provide clear documentation and evidence of due diligence for audits, regulator enquiries and client requirements.

• Environmental contamination of surface water, groundwater and sensitive ecosystems
• Manual handling and plant interaction risks associated with excavation and soil movement
• Fire and explosion risks from volatile or flammable contaminants
• Inadequate decontamination leading to take‑home contamination for workers and their families
