Phase I Environmental Site Assessment
Phase I involves reviewing information on historical and present land use to determine the presence of areas of potential environmental concern (APECs), potential contaminants of concern (PCOCs), hazardous materials, waste and other substances that may negatively affect future use of the property. The assessment includes review of historic and current use of the property, along with a site inspection to look for potential indicators of contamination. Sampling is not included within the scope of the Phase I ESA.
Phase II Environmental Site Assessment
Phase II involves testing the subsurface of a property to verify APECs found during Phase I. This involves soil and groundwater sampling, and comparing laboratory results to the applicable guidelines. Results are also compared to those found at upgradient and downgradient locations, ensuring proper baselines are established. This phase attempts to delineate the full extent of a contaminant(s), both vertically and horizontally such that a proper remediation action plan (RAP) can be developed.
Phase III Environmental Site Assessment and Remediation
Phase III includes the development of a RAP, which will layout the various remediation options available and their respective costs and timelines. This phase also includes the execution of the decided RAP. Frequent contact is maintained with regulatory bodies, and site progress is documented. A formal report is submitted, which includes laboratory results, verifying that remediation has occurred.
