Environment and Technology

CDM Smith delivers data-driven solutions to manage contaminated land, groundwater, hazardous materials, waste, and compliance risks. We combine technical expertise and innovation to support sustainable, compliant outcomes.

Integrated Environmental Solutions for Complex Challenges  

Managing environmental risk requires technical depth, regulatory insight, and practical implementation expertise. CDM Smith’s Environment and Technology practice delivers integrated solutions across contaminated land, groundwater, hazardous materials, waste and ground gas management, risk and toxicology assessment, and environmental auditing.

By combining scientific rigor with innovative tools, we provide accurate data, clear reporting, and defensible strategies that support compliance, reduce liability, and advance sustainability objectives. From initial investigations through remediation and asset closure, we work collaboratively with clients to deliver cost-effective, reliable outcomes that protect communities, safeguard the environment, and support long-term operational success.

Contaminated Sites  

Our contaminated sites services focus on identifying, assessing, and managing sites impacted by hazardous substances. We provide comprehensive site investigations, including preliminary and detailed assessments, to determine the nature and extent of contamination. Our approach ensures compliance with regulatory frameworks and supports sustainable land use planning. Key activities include soil sampling, contaminant profiling, and risk-based remediation strategies using innovative tools and state-of-the-art technology.

Groundwater Assessment  

Groundwater quality and movement are critical to environmental health and regulatory compliance. We conduct hydrogeological investigations to evaluate groundwater contamination, migration pathways, and potential receptors. Our services include groundwater monitoring, aquifer characterization, and predictive modelling to inform remediation design and protect water resources.  

Remediation and Compliance  

We deliver tailored remediation solutions that address contamination effectively while meeting statutory requirements. Our team develops remediation action plans, implements in-situ and ex-situ treatment technologies, and monitors performance to ensure compliance with environmental standards. We also provide and support regulatory liaison and reporting to streamline approvals and project delivery.  

Hazardous Materials Assessment and Management  

Managing hazardous materials is essential for workplace safety and environmental protection. We offer identification, risk assessment, and management strategies for asbestos, lead, PCBs, and other hazardous substances. Our services include surveys, removal oversight, preparation of management plans, and compliance documentation aligned with national codes and standards.  

Risk Assessment and Toxicology  

Our risk assessment and toxicology services evaluate potential human health and ecological impacts from chemical exposure. We apply quantitative and qualitative methods to assess exposure pathways, dose-response relationships, and cumulative risks. These assessments inform decision-making for remediation, land use, and regulatory compliance.  

Audit Services  


Our audit services deliver independent evaluations of environmental performance, compliance, and risk management systems. We conduct due diligence audits, environmental audits in line with legislation, site suitability audits, regulatory compliance reviews, and operational assessments to identify gaps and recommend improvements. These audits support informed decision-making and demonstrate commitment to best practices and standards.  

Waste & Ground Gas Assessment and Management  

We provide solutions for managing solid and liquid waste streams, ensuring safe disposal and regulatory compliance. We are experienced in managing legacy landfills and associated issues. From infill development through to operational facilities, our ground gas assessments identify risks from methane, carbon dioxide, and other gases associated with landfills or contaminated sites. Mitigation strategies include gas monitoring, barrier systems, and ventilation design to protect site integrity and human health.

Our Approach  

Our Environment and Technology services combine scientific expertise with innovative solutions to address complex environmental challenges. We partner with clients across industries to deliver sustainable outcomes that protect ecosystems, safeguard public health, and ensure regulatory compliance. By leveraging advanced technologies and data-driven approaches, we provide accurate assessments, effective remediation strategies, and proactive risk management.  

From contaminated land and groundwater investigations to hazardous materials management and waste solutions, our team applies best-practice methodologies to minimize environmental impact and optimize resource use and opportunities. We integrate risk assessment and toxicology to inform decision-making, ensuring that projects meet stringent safety and compliance standards while reducing long-term liabilities, commensurate with the risk.  

Beyond technical excellence, we are committed to creating positive impacts for communities. Our work helps restore land for safe redevelopment, protect water resources, and manage environmental hazards responsibly. Through transparent communication and collaborative planning, we empower stakeholders to make informed choices that balance economic growth with environmental stewardship.  

By combining innovation, compliance expertise, and a deep understanding of environmental systems, we deliver solutions that not only meet client objectives but also contribute to healthier, more resilient communities.
