We believe there are a number of aspects to our philosophy and capabilities that distinguish us as an environmental site assessment and remediation consulting source. Although Phase I and Phase II ESA-related services require a specific set of skills, the ability to provide comprehensive environmental consulting services for our clients as part of a remediation project is also of great importance.
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 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.
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.
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.
Cornerstone provides a complete range of environmental services with our staff of over fifty employees.
