Phase I Environmental Site Assessments

EEC provides site assessments for organizations and individuals involved in property transactions to assess potential environmental risks to the property and to retain protection from liability under CERCLA. Environmental site assessments prepared by EEC meet or exceed ASTM Standard of Practice E-1527, while providing the necessary due diligence and disclosure required for property transactions. Components of a Phase I may include:

• Review of Provided Information
• Records Review (Local and Federal)
• Physical Setting
• Historical Use Information
• Site Reconnaissance
• Interviews

Phase II Environmental Site Assessments

A Phase II ESA is undertaken if serious environmental concerns are suspected following the Phase I ESA. The purpose is to identify the limits and quantities of potentially hazardous materials; and to evaluate the pathways whereby contaminants could reach receptors. Components of a Phase II may include:

• Borehole drilling
• Air, soil, rock and groundwater sampling
• Selected materials (e.g. for asbestos, PCB's, CFCs, mercury, arsenic, etc.
• Test pit excavation
• Chemical analysis of sampled materials
• Risk assessment
• Analysis, modeling and reporting

Phase III Remedial Investigations

A Phase III ESA is conducted when it becomes evident from prior work that on-site contamination poses a threat to human health or the environment. In this situation, contaminants occur at concentrations above maximum acceptable limits, down-gradient receptors are at risk, and site clean-up is required. A recommendation is made as to the most cost-effective and environmentally-appropriate remediation scheme. Components of a Phase III may include:

• Removal of contaminated soil
• On-site or in-situ treatment of soil or groundwater
• A monitoring plan
• A decommissioning plan
