PHASE II INTRUSIVE ASSESSMENT

Expert Guidance

Information accumulated during the completion of a Phase I Environmental Site Assessment often times indicates that the potential for chemical contamination from either on-site or nearby activities is high. Some of our clients engage a Phase II Environmental Site Assessment to establish the baseline soil and groundwater condition at a proposed site prior to acquisition of a site.

A Phase II Environmental Site Assessment (ASTM Practice E 1903) may be either non-invasive or intrusive and involve investigation for subsurface concerns such as buried tanks and drums using ground-penetrating radar. A Phase II ESA may also involve physical sampling of surface and subsurface media to include air, soil, sediment, surface water and groundwater. The samples are often field screened and then subjected to laboratory analytical testing for various compounds. The Phase II ESA includes development of a work plan in which the specific sampling plan, chemical testing plan, and quality assessment/quality control procedures are defined. Field and laboratory analytical techniques for petroleum and hazardous materials are usually defined by existing EPA and ASTM standards. A Phase II ESA may be cursory in nature to provide a screening for suspect concerns or it may involve a comprehensive geological investigation that incorporates well installation, sampling and laboratory analysis with modeling and analysis of groundwater flow characteristics, contaminant distribution, contaminant fate and transport and risk analysis

Enviro Probe provides cost effective services to meet our client’s Phase II needs. Please contact us to discuss.
