During the course of a Phase I Environmental Site Assessment (ASTM E1527-13), Gabriel attempts to document soil conditions through visual observations, regulatory database review, and historic document review.
Visual observations may include:
- Above-ground storage tanks
- Evidence of underground storage tanks (eg: vent stacks or fill ports)
- Staining or corrosion
- Stressed vegetation
- Pools of liquid
- Hazardous materials
- Septic systems or cesspools
- Geological/topographical observations
Regulatory database and historic document review may include:
- Underground Storage Tank (UST) installation or removal records
- Leaking USTs
- Past uses of property
- Records of hazardous materials usage and/or violations
- Environmental remediation/clean up
- Fire insurance maps
If a Recognized Environmental Condition (REC) impacting the site’s soil is discovered either through visual observation or a review of regulatory databases or historic documents during a Phase I, Gabriel may recommend soil borings to investigate if there is analytical data showing hazardous substances or petroleum products in, on, or at the property.
