Environmental Due Diligence Services
The importance of understanding environmental liability on a property
being considered for purchase cannot be underestimated. Environmental laws and regulations state that
the current property owner is responsible for contamination that exists on their land even if a previous
owner caused it. A thorough due diligence Environmental Site Assessment (ESA) is money well spent.
When CES performs an ESA, we coordinate with appropriate regulatory officials and are familiar with
local, state, and federal regulations associated with site remediation work.
All ESA work performed by CES is in compliance with the most current American Society for Testing and Materials
(ASTM) Standards. CES follows the protocols outlined in ASTM Standard E1528 for the Transaction
Screening Process, Standard E1527 for the Phase I ESA, Standard E1903 for Phase II ESA work, and
the ASTM Standards generated by Committee D-18 for site characterizations.
- Phase I/II/III ESA's
- Environmental Audits
- Ecological and Human Health Risk Assessments
- Contaminant Release Investigations
- Soil and Groundwater Remediation System Design and Installation
Phase I ESA (ASTM Standard E1527)
Phase I ESA work under Standard E1527 typically includes a detailed site
description, physical setting review (aerial photographs, interviews, etc.) and a site reconnaissance visit.
Also included are a hazardous materials review, photographic documentation and preparation of a detailed
report with appropriate conclusions and recommendations. ESA work performed under this standard is typically
done at commercial properties, industrial properties and any other property having a known history of
environmental issues or for a property that may have been impacted by an adjacent property. A recommendation
is made, if appropriate, regarding the need for further site investigation under a Phase II ESA.
Phase II ESA (ASTM Standard E1903)
Phase II ESA work involves collecting additional data from a site where an
environmental condition(s) was identified in the Phase I transaction screen process of the E1527 standard
process that poses an environmental risk or liability. Phase II ESA work is specific to the problem identified
and can vary considerably. The objective is to determine if existing site conditions require further
environmental action such as monitoring or clean up and remediation work. CES prepares a detailed report
summarizing the work performed and provides recommendation as appropriate.
