Phase I Environmental Site Assessments

A large oil and gas producer tasked Earthmaster with completing 100 Phase I Environmental Site Assessments (ESAs) within three months at a fixed cost per site.

Earthmaster’s specialized team initiated the office portion of the ESAs while field staff conducted site inspections and interviews. Field data was relayed daily to expedite report finalization.

The project, started in late July, was completed ahead of schedule, with all reports delivered by mid-September. Earthmaster also provided a summary table detailing land use, ownership, assessment results, and estimated costs for any necessary follow-up actions.
