A Phase II Environmental Site Assessment (ESA) is a more detailed study that is conducted to assess the nature and extent of environmental contamination at a property. It is typically conducted after a Phase I ESA has identified potential environmental concerns at a site.

The scope of a Phase II ESA may include the collection of additional soil and water samples and the use of specialized equipment to assess the extent of the contamination. It may also include the development of a plan to remediate any contamination that is identified.

Phase II ESAs are typically conducted by a team of environmental professionals with specialized training and equipment. They may include geologists, hydrogeologists, and other specialists as needed.

The purpose of a Phase II ESA is to gather more detailed information about the nature and extent of any environmental contamination at a site, and to develop a plan to address any issues that are identified. This information is often used by property owners and buyers to assess the environmental risk associated with a property and to make informed decisions about whether to proceed with a transaction.
