A Phase II Environmental Site Assessment is an assessment to gather physical information on the soil, groundwater and/or surface water conditions at a site. This process usually involves obtaining and reviewing relevant state or client documentation, preparing a site specific health and safety plan, contacting the utility locating agencies, and procurement of drilling, laboratory, field equipment and other subcontracted services. Field work typically includes advancing soil borings and test probes, installing monitoring wells, collecting test data from soil and water samples for laboratory analysis, and mapping sample locations.
