Phase I ESA

The purpose of a Phase I Environmental Site Assessment (Phase I ESA) is to identify, to the extent feasible, recognized environmental condition with the subject property. Phase I ESA is the most frequently performed service in our environmental due diligence activity. The due diligence activities are performed when a real estate transaction is being considered. Phase I ESA report is frequently a required report for the lending institution.

Phase I ESAs are performed in general accordance with the ASTM procedure E1527-05 (Standard Practice for Environmental Site Assessments; Phase I).

If a site is considered contaminated, a Phase II environmental site assessment may be conducted.

InTEC has performed environmental site assessments for over 15 years in Texas.
