ASTM E 1527-13 Standards are the rules by which Environmental Professionals are to conduct field investigations and create Environmental Site Assessment reports.

 

The previous version, ASTM E 1527-05 and ASTM E 1527-00, each have revisions that create more accurate characterization of site environmental conditions. The ASTM E 1527-13 is the newest ASTM Standards for Environmental Investigations.

 

The major changes that this new standard brings are a revision of the definition of Recognized Environmental Conditions, changing User responsibilities, detailing how regulatory file reviews should be conducted, and assessing vapor migration in Phase I ESAs.  Vapor migration will be counted as a potentially impacted condition.
