Phase II Environmental Site Assessment (ESA) |

for Midland, TX; Odessa, TX; Abilene, TX; San Angelo, TX; Lubbock, TX; Houston, TX; Dallas, TX; Fort Worth, TX; Hobbs, NM; Carlsbad, NM; Lafayette, LA & the Surrounding Areas 

A Phase II Environmental Site Assessment (ESA) is an in-depth investigation that involves physical sampling and laboratory analysis of soil, groundwater, and/or soil vapor to confirm and quantify the presence of hazardous substances and petroleum products. It is recommended after a Phase I ESA identifies potential contamination and is used to evaluate the extent of the problem and determine liability before a real estate transaction is completed. eTech Environmental & Safety Solutions, Inc’s Phase II environmental site assessments include the development of site-specific sampling plans, soil and groundwater investigations, monitoring well installation, soil vapor assessments, and laboratory analysis for contaminants commonly associated with historical site operations, underground storage tanks (USTs), mold, asbestos, and lead-based paint. We're dedicated to protecting industrial developers and commercial businesses throughout Odessa, Midland, Dallas, Fort Worth, Houston, Lubbock, Abilene, San Angelo, TX; Denver, CO; Oklahoma City, Tulsa, OK; Hobbs, NM; and the surrounding areas.

What Happens During a Phase II ESA

  • An environmental professional develops a sampling plan based on the findings of the Phase I ESA.
  • They conduct physical sampling, which may include collecting soil samples from boreholes or test pits, or installing monitoring wells to collect groundwater samples.
  • Samples are sent to an accredited laboratory for analysis to determine the presence and concentration of specific contaminants.
  • Common contaminants evaluated include mold, asbestos, lead-based paint, and chemicals often related to Underground Storage Tanks (USTs) or previous site operations.

When Is It Required?

  • A Phase II ESA is typically required after a Phase I ESA indicates that there are “Recognized Environmental Conditions” (RECs) on the property that require further investigation.
  • It is often necessary for properties being redeveloped or purchased where potential environmental risks need to be quantified.

What Is the Outcome?

  • A comprehensive report details the sampling methods, laboratory results, data interpretation, and recommendations for further action.
  • The results help the buyer or owner understand the scope of contamination, negotiate price, and determine if cleanup is needed.
