Columbia West prepares Phase I Environmental Assessments (ESA) for a wide variety of residential and commercial clients. A Phase I report is conducted to evaluate environmental conditions and potential issues resulting from current or past activities at a site. Phase I reports are performed in general accordance with ASTM E 1527-13 to comply with “all appropriate inquiry” standards. Detailed reviews of environmental records from federal, state, and local agencies are conducted to identify past and current environmental conditions. Past owners and occupants, government and agency officials, and others who may have relevant environmental information about the site are interviewed. Site reconnaissance including observations of the subject property, its current and past uses, structures located at or near the site, as well as observations of the geologic, hydrologic, and topographical conditions is also conducted. The findings and conclusions of the site assessment are evaluated and summarized in a final report.
