Environmental Site Assessments

In order to protect against environmental liabilities, it is critical for commercial property purchasers to conduct appropriate due diligence prior to acquisition of a site. Liberty Environmental has conducted thousands of Phase I Environmental Site Assessments and other due diligence assessments. Through our involvement in ASTM Committee E50, we stay ahead of the curve in the latest standards for conducting All Appropriate Inquiry on a wide array of property types. Our experience and knowledge enable us to communicate the real environmental risks and propose common sense solutions to prospective purchasers, their lenders and attorneys. Our deep expertise in the management of environmental projects for real estate transactions and funding extends from private sector to government-guaranteed loan programs such as SBA protocols, HUD Environmental Reviews and NEPA studies.

Remedial Investigations and Feasibility Studies

Today’s risk-based approach to corrective actions at brownfield, hazardous waste and other contaminated sites requires a high level of scientific expertise and an understanding of federal and state regulatory programs. Application of our expertise in contaminant fate-and-transport modeling, risk assessment and use of institutional and engineering controls, ensures that remedial efforts are guided by informed decision making that takes into account the planned site use and human exposure pathways. Liberty Environmental’s experience in this area places our clients at the forefront of this rapidly changing, innovative field. Our staff has completed site investigations under a wide range of programs including:

• Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA, or Superfund)
• Resource Conservation and Recovery Act (RCRA)
• State Storage Tank Programs
• Voluntary Cleanups (including brownfields redevelopment)

We have experience with a full spectrum of geological and ecological conditions that can be encountered at a project site–including sanitary landfills, hazardous waste landfills, lagoons and impoundments, operating manufacturing plants, abandoned disposal sites and waste piles.

Storage Tank Management

Liberty Environmental’s storage tank services span many levels of tank management, including spill plan development, tank removal oversight and corrective action. Our staff, who frequently presents to national audiences on the subject, has managed thousands of storage tank removals, leaking tank investigations and remediations. Through our understanding of modern technological developments in tank materials, appurtenances and containment devices, we are able to assist our clients in avoiding.

Soil and Groundwater Remediation

Engineered remediation systems remain a large part of environmental cleanup solutions, and our team of experts brings an unequaled level of complementary skills to our system designs. Through the collaborative efforts of our diverse team of scientists and engineers, we design and operate efficient, innovative treatment systems designed to fit each site’s unique setting and remedial objectives. Our applied remedial technologies have included:

• In-Situ Bioremediation
• In-Site Chemical Oxidation
• Multiphase Fluid Extraction
• Physical and Biological Ex-Situ Treatment
• Phytoremediation
• Soil Vapor Extraction, Air Sparging and Bioventing

Most importantly, our investigative and remedial solutions are designed, engineered and operated with one overriding objective–to achieve site cleanup and re-use goals on time and under budget.

Vapor Intrusion Mitigation

Vapor intrusion has emerged as one of the most significant human health concerns on contaminated properties. After vapor intrusion modeling or soil gas sampling conclude that vapor intrusion is a concern, Liberty’s engineering team evaluates mitigation options, completes data-led design in coordination with other design professionals, and oversees installation of system components such as vapor barriers and sub-slab ventilation systems.
