Services
Industrial Wastewater Treatment
We specialize in optimizing industrial wastewater treatment systems to achieve regulatory compliance and cost efficiency. Our engineers analyze existing processes, implement system upgrades, and identify water reuse opportunities. With expertise in food processing, pulp and paper, and oil and gas sectors, we help clients reduce surcharges through tailored treatment solutions.
Site Assessment and Remediation
Our Phase I and II environmental site assessments identify contamination liabilities following ASTM standards. We conduct regulatory-compliant investigations and develop remediation plans for contaminated properties. Our team manages cleanup projects from initial assessment through final regulatory approval for commercial, industrial, and municipal clients.
Environmental Compliance
We navigate complex environmental regulations for NPDES permits, stormwater management, and industrial compliance. Our team prepares spill prevention plans, conducts compliance audits, and secures permits for wastewater discharge, land disturbance, and water withdrawal activities across multiple industries.
Water Quality Modeling
With 30+ years of experience, we develop advanced water quality models to assess environmental impacts of development projects. Using in-house Hach laboratory equipment, we provide rapid testing and analysis to support permitting decisions for municipalities, regulatory agencies, and private clients.
Master Planning
We create comprehensive master plans for water and wastewater infrastructure modernization. Our planning addresses aging systems, capacity upgrades, and regulatory compliance while balancing technical requirements with budget constraints for municipalities and industrial facilities across the Southeast.
