What is a Phase 1 Environmental Site Assessment?
And why would somebody need one?

Phase 1 ESAs

Over the years, the world has grown more environmentally conscious of the risks associated with different areas of the planet due to naturally occuring substances as well as the misplacement of man-made ones.

Given this heightened, but necessary awareness, it is crucial for companies, as well as individuals, to assess their environmental risk as it relates to their particular piece of property. That's where Environmental Site Assessments, or ESAs, come in.

Phase 1 Environmental Site Assessments are one type of environmental site assessment that can give the client an overview of existing or potential environmental impairments.

How Is This Achieved?

Interview

The current owner and other related parties are asked a variety of questions that can help determine the condition and history of the site as well as any known risks. Often times, these individuals are able to give clues that can help the environmental specialist predict types of contamination that may be present on site.

Site interview

Historical Documents

Old historical maps spread out

After the interviewing process, a trained professional combs through the historical documents of a location to find any points of interest. This can include looking through historical maps, aerial photography as well as federal, state, and local environmental records.

These documents are one piece of painting the environmental situation, but a crucial one as they can show previous structures on the site that might have impacted the property or ones that have been previously identified.

The property is then visited in-person to survey any potential locations for soil sampling and anything else that may have gone unnoticed in the historical research.

Soil Sampling & Lab Analysis

Analyzing lab sample

Soil samples are collected from the site to determine if any contaminants are present. The samples are then laboratory tested for a variety of contaminants. Their levels are recorded with a scale indicating adherance with the Maximum Allowable Concentrations of the various substances.

Reporting

All of the previous information is compiled into a report and a recommendation is given as to any actions that may be needed on the site. This report is then presented to the client who can then decide if they want to pursue any other soil testing or remediation.
