Frequently Asked Questions

A Phase 1 Environmental Site Assessment (ESA) is a study of a site to evaluate the probable presence of environmental hazards and estimate the risk, threat, and possibility of human health and environmental damage, including any issues that might arise. Typically, this evaluation is the initial phase of due diligence for a property sale or financing, and it is conducted by an environmental specialist with knowledge and expertise of environmental legislation and standards. The evaluation includes a study of relevant historical and government data, a site inspection, and an evaluation of potential environmental concerns such as hazardous waste, soil and groundwater pollution, and underground storage tanks. The purpose of a Phase 1 ESA is to identify any recognized environmental conditions (RECs) and provide any appropriate recommendations for future action to address any potential issues.
