ESA SERVICES - Phase II Environmental Site Assessment (ESA)

Soil boring investigations are conducted to establish actual soil and groundwater conditions and determine contaminant levels. RRC employs various techniques to gather subsurface information including:

¨ Hand auger soil sampling

¨ Direct-push (Geoprobe) soil and groundwater sampling

¨ Soil sampling and monitoring well installation with conventional auger drilling

¨ On-site analysis and field screening

¨ Cone penetrometer testing with down-hole analyses

¨ Passive sampling devices

 

 Phase II investigations are designed to include any combination of the above referenced techniques in order to gather the information needed at the most reasonable cost and with the least disturbance to the property. All samples are analyzed in laboratories certified for the appropriate state regulatory program.

SERVICE AREAS

RRC typically performs Phase II ESAs to address issues raised in the Phase I ESA.  The Phase II ESA involves invasive sampling and analysis of the soil, groundwater or other media on site. The purpose of the Phase II ESA is to confirm the presence of contamination on the property due to known or strongly suspected environmental concerns. We generally recommend that a full Phase I ESA be performed prior to a Phase II ESA, even when environmental issues are known or strongly suspected ahead of time. The Phase I ESA also evaluates off-site issues and may identify unknown issues.

RRC has investigated and assessed soils, sediments, air, indoor air, groundwater, surface water, building surfaces, and bedrock . We have experience in evaluating the nature and extent of environmental contamination in a variety of media through historical property research, sampling, data analysis, testing of the media physical characteristics, fate and transport modeling, etc.
