What is a Phase II Site Investigation?

A Phase II is testing for a suspect environmental problems that were found from a Phase I. It is normally performed after a Phase I, as a Phase I is meant to identify environmental Recognized Areas of Concern (AOCs) BEFORE a property is purchased.  The Phase I protects a buyer from buying a property that has environmental problems that would lower the value of the property.  


While a Phase I needs to be performed by an environmental professional with experience and training a Phase II typically requires drilling and testing equipment.  Curren Environmental owns and operates drilling, GPR, metal detectors and testing equipment necessary to quickly and cost effectively complete a Phase II.  Without having to subcontract services needed for a Phase II, our clients realize a savings of in house work with no subcontractor markup.

     A Phase II Can Include

Phase II GPR survey

             Geophysical Survey

   (Ground Penetrating Radar - GPR)

            Metal Detector Sweep

                 Soil Testing

          Groundwater Sampling

                     Test Pits



Phase II geoprobe soil sampling   Vapor Intrusion Evaluation

                Soil Testing

         Exploratory Excavtion

         Groundwater Testing

               Mold Testing

Where a Phase I is a paper research and physical inspection of a property, a Phase II typically involves physical evaluation  and/or testing at a property. A Phase II is performed to help answer questions that arise in a Phase I such as, are there buried tanks; does contamination exist from past operations at the property? To answer these questions, a Phase II may include a metal detector survey or Ground Penetrating Radar (GPR) survey of a property to locate suspect Underground Storage Tanks (USTs). A Phase II may also consist of advancing soil borings to collect both soil and groundwater samples from areas of a property where contamination may be present, based on the Phase I report.

Investigative soil borings are collected in Environmental Areas of Concern (AOCs) as listed in the Phase I. The samples are collected by experienced project managers following State and Federal regulations with the samples collected shipped to a laboratory for independent analysis.

A Phase II ESA report should describe the investigative activities completed, detailing soil borings performed, environmental phase II and the soil and ground water analytical results as  compared to applicable state standards. Conclusions are then drawn from the data collected. If conditions are identified that may require remediation the recommendations section of the report will discuss options available as well as costs for addressing each Area of Concern.   A Phase III will follow a Phase II if additional work is required.
