What Are Environmental Site Assessments (ESA)?
Environmental site assessments

The main purpose of a Phase 1 ESA (environmental site assessment) report is to assess if current or historical property uses have impacted the soil or groundwater beneath the property and could pose a threat to the environment and/or human health. If these environmental issues and threats are found, it presents a potential liability for the lender and/or owner of the property, as well as affecting the value of the land.

 

A Phase I ESA completed prior to the closure of a real estate transaction can be used to meet the requirements of CERCLA’s (Comprehensive Environmental Response, Compensation and Liability Act) innocent landowner defense under All Appropriate Inquiries (AAI). Our local team of environmental consultants is professionally trained & experienced in performing detailed ESAs (Environmental Site Assessments) in Kansas.

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 staff of geologists and engineers possess expertise in Phase II Environmental project design. 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, Titan knows the most important pieces of information necessary are:

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

Drilling methods used most often during Phase II Environmental Testing projects:

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

Our staff is also familiar with other subsurface drilling technologies, such as sonic drilling, telescope drilling, air rotary, and solid stem auger. All these technologies are important options.

Soil Gas Sampling

When the Phase II Environmental Site Assessment is being done to investigate volatile organic compounds (VOCs), the geologist 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. Titan is very experienced with proper collection techniques for soil gas sampling projects.
