Phase 1 ESA

The purpose of a Phase I ESA is to identify, to the extent feasible, Recognized Environmental Conditions (RECs) in connection with a site and will provide a professional opinion as to the potential for contamination from hydrocarbon or hazardous waste to exist, which may require remedial action.

Phase 2 ESA

Phase II ESAs are conducted in order to obtain further understanding of the potential environmental liabilities for a property and the financial impacts of such liabilities and involve the collection and analysis of soil, groundwater, and/or site building materials to assess the presence and extent of hazardous chemicals that are suspected or have been identified during the Phase I assessment.

Remediation

• Characterize the extent of groundwater contamination
• Assess health risks
• Identify and review potential remedial action alternatives
• Determine the feasibility of implementing these alternatives
• Select and implement the most appropriate cleanup strategies

Methodology

Risk-Driven Site-Investigation Approach:

Our planning focuses on site investigations that are “risk-driven.” This approach allows us to identify the most efficient and cost-effective site remedy at the outset of the investigation. Our risk-driven approach prevents the collection of unnecessary field data and fosters a negotiating stance with regulators that minimizes the potential for major expansions of scope later.

Primary Attention to Realistic Approaches:

The key limitation of the typical practice of site assessment is the naive use of guidance as a legal directive and the simplistic use of inappropriate and/or overly-conservative cleanup goals or standards rather than realistic approaches to estimate exposure and potential health risk.

Environmental Compliance Resources:

Cornerstone provides a complete range of environmental services with our staff of over fifty employees.
