Phase I Environmental Site Assessments (ESAs)

Hammontree and Associates performs Phase I ASTM and VAP ESAs for properties, including industrial, commercial, agricultural and residential. We assess properties according to ASTM and VAP standards taking into consideration potential risks associated with this property. The purpose of a Phase I ESA is to use a systematic approach to identify any existing or potential environmental conditions that may be present or affect a real estate property. Hammontree and Associates are experts at the implementation of the ASTM E1527-13 Standard.
