Services
Phase I ESA
Phase I Environmental Site Assessments identify potential contamination risks through historical research and site inspections. Our ASTM-compliant evaluations help property buyers understand environmental liabilities before transactions. This non-invasive assessment forms the foundation for real estate due diligence decisions.
Phase II ESA
Phase II ESA involves intrusive testing when potential contamination is identified. We conduct soil sampling, groundwater analysis, and laboratory testing to confirm contamination presence. Our detailed reports help clients determine remediation needs and associated costs for regulatory compliance.
Indoor Air Quality
We assess indoor air quality through mold, radon, and vapor intrusion testing. Our evaluations identify health hazards from airborne contaminants in commercial and residential buildings. We provide remediation recommendations to ensure safe indoor environments meeting regulatory standards.
Hazardous Waste Services
Our hazardous waste services include waste characterization, compliance audits, and disposal guidance. We help businesses manage regulated materials through proper handling, storage, and documentation. Our solutions minimize environmental impact while maintaining regulatory compliance.
Environmental Compliance Audits
We conduct comprehensive compliance audits to evaluate environmental regulatory adherence. Our assessments cover air quality permits, waste management practices, and spill prevention measures. We identify gaps and provide actionable plans to achieve and maintain compliance with federal/state regulations.
