Environmental Site Assessment
Phase I and II Environmental Site Assessments identify environmental risks through systematic evaluations of soil, groundwater, and subsurface conditions. Our assessments comply with ASTM standards and regulatory requirements, providing defensible data for real estate transactions, construction projects, and remedial actions. With hundreds of completed assessments across diverse sites, we deliver cost-effective solutions tailored to client needs.
Environmental Remediation
We implement customized remediation strategies for petroleum and solvent contamination using proven technologies like soil vapor extraction and groundwater treatment. Our approach balances regulatory compliance with client objectives, achieving successful site closures through methods like natural attenuation and product recovery. Decades of experience with Superfund sites and industrial facilities ensure effective solutions for complex contamination scenarios.
Hydrogeologic Studies
Our hydrogeologic studies evaluate groundwater flow, contaminant transport, and aquifer characteristics to inform remediation strategies. We analyze interactions between groundwater, surface water, and soil to develop sustainable water resource management plans. This technical expertise supports regulatory compliance and long-term environmental protection for communities and industries.
Regulatory Compliance
We navigate complex environmental regulations through strategic agency negotiations and compliance audits. Our team ensures projects meet federal, state, and local requirements while maintaining operational efficiency. With deep regulatory knowledge, we facilitate permit acquisition, compliance reporting, and resolution of enforcement actions for industrial clients.
Vapor Intrusion Assessment
We assess subsurface contamination impacts on indoor air quality through comprehensive vapor intrusion evaluations. Our methodology identifies hazardous vapor pathways in existing structures, providing data-driven recommendations for mitigation. This service protects occupant health while ensuring compliance with environmental regulations for contaminated sites.
