Site Assessment, Remediation & Closure

Site-specific investigation planning starts with a review of site features and known or suspected conditions. Phase I and Phase II Environmental Site Assessments help clarify environmental conditions and better understand potential risks and liabilities. Findings support a practical, risk-based approach that manages environmental liabilities in line with current operations or redevelopment plans while meeting regulatory and stakeholder expectations.

End-to-end remediation system support spans evaluation and design through installation, start-up, and operation and maintenance. We tackle complex site conditions by tailoring technology solutions for in situ and ex situ soil, sediment, and groundwater remediation to manage risk and reduce liability. A single point of contact reduces contractor oversight and costly scope changes.

Predictive land reclamation services support site closure and return impacted land to a productive or natural state in line with applicable requirements. We develop site-specific plans and monitoring programs that support closure documentation and long-term performance tracking to efficiently reduce liability.

Integrated services, including assessment and resiliency grant assistance, help build successful programs for brownfield redevelopment. Experienced guidance and technical documentation support credible, fundable approaches that align with regulatory requirements and stakeholder expectations. The result is clearer progress toward community revitalization goals and site reuse.

Spill response experience and long-standing relationships with regulators support efficient cleanup aligned with regulatory expectations. Capabilities span small, routine releases to large-scale, multidisciplinary emergencies, including high-visibility incidents. Proactive support also includes risk assessment and ranking, emergency response procedures, and spill prevention program development.

Highly skilled construction personnel work alongside geologists, hydrogeologists, engineers, and other environmental professionals to deliver safe, economical excavation and earthwork in any setting. Certified Construction Review (CCR) support is available when project requirements call for added oversight and documentation. Demolition ranges from small residential structures to large commercial and industrial facilities with environmental concerns, using efficient methods to segregate, recycle, and salvage debris.

Responsive dewatering support covers clean and contaminated groundwater from permitting through system installation and operation and maintenance. Discharge sampling, monitoring, and reporting are managed to align with applicable requirements. Treatment options include liquid-phase carbon and bag filtration systems selected to match site conditions and discharge goals.

Storage tank closure and management support covers underground storage tanks (USTs) and aboveground storage tanks (ASTs), including removal and proper disposal of tanks and contents. Soil sampling and laboratory analysis from UST excavations, plus agency coordination and reporting, support compliant closure.
