Environmental and Contaminated Land Consultants
Confluence Environmental is an independent environmental consultancy providing specialist expertise across contaminated land, environmental consulting, occupational hygiene and asbestos and hazardous materials for industries across NSW and beyond
Our Story
Confluence Environmental was established to provide clear, practical, and science-led environmental consulting across contaminated land, environmental assessment, occupational hygiene and asbestos and hazardous materials. Our focus is on helping clients understand site conditions, manage contamination and exposure risks, and achieve regulatory compliance across development, construction, infrastructure, and industrial projects.
Our work centres on the assessment and management of contaminated land, environmental risk, groundwater and surface water, waste classification and material reuse, occupational exposure, and hazardous materials. Through structured environmental assessment, technical evaluation, and clear, defensible reporting, we support planning, remediation, compliance, and long-term environmental risk management in accordance with NSW EPA guidelines and environmental regulations.
Confluence Environmental was founded on the principle that effective environmental consulting must combine technical rigour with practical application. We work closely with developers, planners, engineers, contractors, government, and industry to identify environmental constraints early, assess contamination and exposure pathways, and deliver regulator-aligned solutions that protect human health and the environment while supporting sustainable project outcomes.
Based in New South Wales, Confluence Environmental supports projects across Sydney, the Central Coast, Newcastle, the Hunter Valley, and regional NSW, delivering responsive and technically grounded expertise in environmental consulting, contaminated land, occupational hygiene, and waste management. As our clients and projects have grown, our capability has expanded to meet the evolving environmental and regulatory needs of the communities and industries we support.
Today, Confluence Environmental remains focused on delivering accurate, reliable, and practical environmental consulting helping clients manage environmental risk, achieve regulatory compliance, protect human health and the environment, and move projects forward with confidence.
