ESE staff conducted Phase I Environmental Site Assessments (ESAs) for four properties near Oklahoma City, including an oil/gas service facility, a medical clinic, a retail space, and farmland with a residence. The assessments adhered to ASTM E1527-21 standards and included visual asbestos evaluations. Research included environmental database records, historical sources, interviews with local municipalities and property owners, and visual inspections. The gathered due diligence information helped the client identify environmental risks in preparation for property divestiture.
