Environmental Site Assessments
Our Phase I and II environmental site assessments identify contamination risks and regulatory compliance requirements. We conduct regulatory audits, spill prevention planning, and remedial action design for industrial and commercial properties. Our licensed professionals ensure accurate classification and remediation strategies.
Underground Storage Tank Removal
We safely remove underground storage tanks ranging from 500 to 25,000 gallons. Our licensed contractors handle remedial excavation, disposal, and LUST reporting. We ensure compliance with state and federal regulations to minimize environmental liability for property owners.
Direct Push Soil Sampling
Our AMS 9600 PowerProbe rigs collect continuous soil samples up to 100 feet deep. This method provides accurate geologic characterization and contaminant analysis while minimizing site disruption through compact equipment access.
In-Situ Remediation
We implement bioremediation and chemical oxidation solutions using high-pressure injection systems. Our proprietary software designs customized treatment plans for contaminated soils and groundwater, achieving efficient contaminant breakdown with minimal site disturbance.
DOT Contracting Services
Our IDOT and MoDOT prequalified teams perform excavation, grading, drainage structures, and signage installation. We handle erosion control, slope stabilization, and pavement patching for transportation infrastructure projects across the Midwest region.
