Phase II Environmental Site Assessments (ESA) / Subsurface Investigation

A Phase II Subsurface Investigation is designed to assess and evaluate potential environmental contamination in the subsurface at a specific site. The Phase II Subsurface Investigation is typically conducted following the completion of a Phase I Environmental Site Assessment (ESA) and aims to further evaluate identified recognized environmental concerns or potential sources of contamination, to understanding the impact of hazardous substances on soil, soil vapor and groundwater quality.

Purpose and Importance:
The primary purpose of American Environmental Phase II Subsurface Investigation is to provide a comprehensive understanding of site conditions and potential environmental risks. By identifying and assessing contaminants in the subsurface environment, property owners and stakeholders can make informed decisions regarding site development, remediation strategies, and regulatory compliance.

What does our Phase II Subsurface Investigation Involve?
American Environmental Phase II Subsurface Investigation process is designed to be thorough, efficient, and cost-effective.

American Environmental approach to conducting Phase II Subsurface Investigation Include
Site Characterization: We begin by conducting a comprehensive site characterization, gathering information about the Site’s history, geology, hydrogeology, and potential sources of contamination at the site.
Field Investigation: Our experienced team conducts detailed field investigations using a variety of techniques, including drilling, soil sampling, groundwater monitoring, and geophysical surveys to collect data from the subsurface. We employ advanced techniques to ensure accurate and representative sampling, minimizing uncertainties and maximizing the value of the data collected.
Sample Collection and Analysis: Samples collected during the field investigation are analyzed in accredited laboratories using state-of-the-art equipment and methodologies. Our laboratory analysis provides precise and reliable data on  he presence, concentration and distribution of contaminants in the soil, soil vapor and groundwater, facilitating risk assessment and remediation planning. Common contaminants include petroleum hydrocarbons, heavy metals, Polychlorinated Biphenyls (PCBs), Pesticides, Herbicides, Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS), 1,4-Dioxane and volatile organic compound (VOCs).
Data Interpretation and Risk Assessment: Data collected during the Phase II Subsurface Investigation are interpreted to assess potential risks to human health and the environment. Factors such as contaminant pathways, exposure routes, and receptor characteristics are evaluated to determine the level of risk associated with the site. The goal is to determine the significance of contamination and its potential impact on site redevelopment or future land use.
Reporting and Recommendations: Upon completion of the Phase II Subsurface Investigation, we provide a comprehensive report detailing our findings, interpretations, and recommendations for mitigation and remediation. Our reports are clear, concise, and actionable, providing you with the information you need to make informed decisions about your project.

Why is Phase II Subsurface Investigation Important?
A Phase II Subsurface Investigation is critical for several reasons:

  • Risk Management: It helps identify potential risks associated with soil, soil vapor, and groundwater contamination, allowing property owners and stakeholders to develop appropriate risk management strategies.
  • Regulatory Compliance: It ensures compliance with regulatory requirements by providing the necessary data and analysis to support environmental decision-making.
  • Site Redevelopment: It provides valuable information for site redevelopment or reuse, helping minimize potential liabilities and ensuring the protection of human health and the environment.
  • Due Diligence: It demonstrated due diligence on the part of the property owners, lenders, and developers, mitigation potential legal and financial risks associated with environmental contamination.
