Environmental Site Assessment Services


Phase I of environmental assessments

Phase I SEA is an investigation that aims to uncover any negative environmental impacts before a real estate transaction occurs. A Phase I SEA is based on examination of the archives of federal, state and local governments and organizations, historical archives, site survey and stakeholder interviews, etc. This process is conducted in accordance with the American Society for Testing and Materials (ASTM) E 1527 - Standard Practice for Environmental Site Assessments.

A phase 

· Establishes recognized adverse environmental conditions in relation to dangerous substances and petroleum products.

Defends innocent homeowners and under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA)

Provides an indication of existing or past emissions or the physical threat of a release of any hazardous substance or petroleum product to structures, soil, groundwater, or surface water at a site.

Phase II environmental assessments of the site

A phase II SEA is an additional investigation into the negative impacts detected during a phase I ESI investigation. It establishes the extent of any contamination or unfavorable condition based on in-depth investigation and makes recommendations on the restoration material. The process is carried out in accordance with ASTM E 1903, Standard Practice for Environmental Site Assessments.

A Phase II SEA may include, but is not limited to, the following:


Soil Sampling

Disposal Services

Groundwater Sampling

Asbestos Surveying

Underground Storage Tank testing and removal support

Microbial Evaluation

Waste Characterization

Lead Based Paint Investigations

Environmental transaction screens

An environmental transaction screen (ETS) is an economical alternative to initially carry out a phase I SEA when certain criteria are met. This selection process is used, unlike a phase I SEA, when information suggests that few adverse environmental conditions will be identified. The transaction filtering process is carried out before the acquisition of the property, in accordance with standard ASTM ASTM E 1528 practice for environmental site assessments.

For the transaction screen:

Establishes Environmental Due Diligence And Innocent Defense Of Landowners Under CERCLA

Requires a site visit

Requires examination of government documents and historical sources

Use a questionnaire to get information about the owner and / or operator of the property.



At the end of any environmental assessment service, the client receives a complete technical report with photographic documentation, site-specific maps, conclusions and recommendations.
