Contaminated Land and Acid Sulfate Soils

Coterra Environment and Western Environmental have formed a partnership (Western Coterra) which enables us to offer a comprehensive and integrated environmental service to address our clients’ growing needs across a range of diverse and challenging projects. Having worked together on numerous projects since 2010, Coterra Environment and Western Environmental now reside in a shared Head Office in Perth, Western Australia.

The advantage of our partnership compared to conventional multidisciplinary consulting firms is two-fold. Firstly, we are experts in our specified fields, rather than generalists, which allows us to develop high-value solutions which drive life-of-project cost efficiencies. Secondly, as smaller organisations we are able to offer pricing structures that are more favourable than our larger competitors. Our team approaches each project in a unique and adaptable way, using focussed problem solving to develop bespoke solutions, rather than taking a ‘one size fits all’ approach.

Through this partnership, we are able to offer the following services in contaminated land;

  • Site contamination: Including contaminated sites strategic planning, site investigations (PSI, SAQP and DSI), remediation design and management, noise and vibration management.

  • Acid Sulfate Soils: Including due diligence and planning, dewatering modelling, treatment and management, compliance and closure reports.

  • Asbestos and Hazardous Material Management: including due diligence, removal control plans, monitoring and inspections.

  • Air quality services: Including monitoring of dust, exhaust products, landfill gas, vapour and ambient air quality, design and management plans.

  • PFAS services: Including conceptual site monitoring, field data collection, remedial action plans, compliance and closure reporting. Western Environmental is currently the lead consultant in a national consortium undertaking field scale trials for several proprietary PFAS soil and groundwater treatment technologies.
