Any real estate holding can be the subject of a Phase I Environmental Site Assessment (ESA), which identifies potential or existing environmental contamination liabilities, or may require the completion of a Phase II ESA.


Due Diligence / Phase I ESA

LTE has provided environmental due diligence and Phase I ESAs that meet American Society for Testing and Materials (ASTM) E1527-05 standards, All Appropriate Inquiry (AAI) requirements, and client-specific requirements at over 5,000 sites across the United States. Our goal is to identify Recognized Environmental Conditions (RECs), assess the need for further investigation via a Phase II ESA, and develop detailed cost estimates for the environmental liabilities identified to support our client’s needs.

We have performed due diligence and Phase I ESAs at complex industrial sites, for multi-state and multi-site properties, on single transactions that included over 650 oil and gas properties, and for inner city and rural sites. Our clients include banks, oil and gas companies, realtors, developers, transportation entities, and industrial manufacturing companies.

LTE combines technical knowledge, extensive experience, familiarity with the ASTM standards, knowledge of federal, state, and local regulations, and cost/benefit analyses to offer reliable assessments of risk and allow our clients to make rational, informed decisions.

Phase II ESAs

LTE has completed thousands of Phase II ESAs across the United States based on ASTM E1903 standards to help clients further identify potential environmental liabilities associated with contaminated soil, groundwater, surface water, sediments, and air, as defined in Phase I ASTM E1527. 

LTE employs an efficient risk-based approach to site investigations, gathering only the data necessary to make cost-effective decisions regarding remediation and cleanup. Our industry leading relational database and geographic information system (GIS) capabilities allow us to gather accurate analytical data for efficient management of data from site investigations; easy access by corporate decision makers; preparation of reports at low cost that meet regulatory and client-specific requirements; and the highest degree of accuracy available. Our use of real-time assessment tools and value-added engineering evaluations save clients time and money.

LTE has performed site investigations with risk assessments and fate and transport modeling to aid in developing appropriate remediation alternatives that protect public health and the environment. LTE has also prepared numerous voluntary cleanup applications in several states based on the site investigation, risk assessment, and modeling.
