PHASE II ENVIRONMENTAL SITE ASSESESMENT (ESA)

When a Phase I Environmental Site Assessment (ESA) identifies a recognized environmental condition or the potential for soil contamination, most clients request to evaluate the potential contamination by performing Phase II Environmental Testing.

The purpose of a Phase II Environmental Report is to determine the presence, or absence of, petroleum products or hazardous waste in the subsurface of the site. Our team of geologists and engineers possess expertise in Phase II ESA discovery and exploration. Our Phase II Environmental projects can be done according to the ASTM E1903-11 Standard Guide for Environmental Site Assessments: Phase II Environmental Site Assessment Process standard or to meet a client’s specific needs.

When designing a Phase II ESA, the most important pieces of information necessary are:

      • Areas of Concern
      • Chemicals of Concern
      • Local geology
      • Site access issues

C&T’s Phase II Environmental Practice is one of the best in the business. Our team is comprised of some of the best geologists and engineers in the business. We deliver our local expertise of geologic and regulatory environments throughout the country.  

Drilling Methods for Phase II Environmental Testing

C&T’s team of engineers and geologists are familiar with a host of drilling technologies and have relationships with some of the best drilling companies around the country. We will choose the best drilling technology to economically meet the goals of the Phase II Environmental Site Assessment. Drilling methods used most often during Phase II Environmental Testing projects:

      • Push Probe
      • Hollow Stem Auger
      • Hand Auger
      • Mud Rotary
      • CPT Drilling

Soil Gas Sampling

When the Phase II Environmental Site Assessment is being done to investigate volatile organic compounds (VOCs), the Environmental Scientist designing the Phase II scope should consider sampling for soil gas instead of, or in addition to, soil samples. Soil gas sampling is particularly advantageous in porous media such as sands. C&T is very experienced with proper collection techniques for soil gas sampling projects.
