When a Phase I Environmental Site Assessment (ESA) identifies a recognized environmental condition (REC) or the potential for impacts to the subsurface at a site, most clients request to evaluate the potential impacts by performing Phase II Environmental Testing. The presence of a REC or an environmentally impacted property can greatly reduce its value. Stakeholders want to reduce liability and future cleanup expenses on their investment by conducting a Phase II ESA, in which a subsurface investigation tests soil, soil gas and/or groundwater to identify sources of environmental impacts.
