DLZ provides solutions to complex environmental challenges. Our multidisciplinary team of engineers, scientists, planners, and technicians delivers proactive, cost-effective solutions across every phase — from initial due diligence through cleanup and redevelopment.
For nearly four decades, DLZ has delivered environmental services across the Midwest for federal, state, municipal, and private-sector clients. Our multi-disciplinary teams allow us to tackle complex, multi-faceted projects.
Environmental Assessments help clients understand site conditions, manage liability, and move brownfield properties confidently toward productive reuse.
Surveys, removal specifications, and compliance oversight for asbestos, lead, PCBs, and other regulated materials. We give owners the documentation and support needed to protect workers, communities, and project schedules.
Comprehensive investigation, assessment, and cleanup services for soil, groundwater, sediment, and surface water contamination. We guide clients from initial characterization and risk assessment through cleanup, closure, and long-term monitoring.
Surface water management, floodplain studies, hydrologic and hydraulic modeling, and permitting support. We help communities navigate complex regulatory requirements and protect against flood risk across the Midwest.
Wetland delineations, threatened and endangered species surveys, ecological assessments, and regulatory permitting support — helping projects advance responsibly while protecting natural resources and meeting federal and state requirements.
Specialized investigation, sampling, risk assessment, and remediation planning for PFAS and other emerging contaminants. We help clients navigate a rapidly evolving regulatory landscape with science-based, practical solutions.
Brownfield demolition planning, hazardous materials management, abatement oversight, and redevelopment support. We deliver complex demolition projects safely and compliantly, with an eye toward what comes next.

Our environmental capabilities span the full project lifecycle, including hazardous materials surveys, Phase I and Phase II environmental site assessments, contaminant investigation and remediation, PFAS services, ecological studies, permitting and demolition support. Having all of these in-house means clients benefit from integrated expertise and a single point of accountability.
We work with federal, state, and local government agencies, municipal and infrastructure owners, and industrial and private-sector clients. Whatever the sector, our approach is the same: practical, cost-effective solutions that protect people and move projects forward.
We work with small municipalities of fewer than 1,000 residents to major urban residents, major urban centers, and private developers to support the productive redevelopment of brownfield properties.
Our teams work with a broad range of regulated materials and hazardous substances including PFAS, petroleum products, chlorinated solvents, metals, asbestos, lead, and PCBs. We address contamination in soil, groundwater, surface water, soil gas, indoor air and building materials, with the technical depth to handle both routine and complex remediation challenges.
