Purchasing or leasing property includes the risk of acquiring environmental conditions caused by previous owners.  The costs of cleaning up or managing the adverse impacts of contamination can vary widely, but even small unanticipated expenses are always unwelcome. Some environmental problems have the potential of significantly impacting the market value of a property.

A properly conducted Environmental Site Assessment (ESA) can provide a good general indication of the past and existing conditions on a site that could indicate a recognized environment condition. The Phase 1 ESA is intended to provide a review of known and observable conditions that allows for the evaluation of environmental conditions at a site or property.

CES uses the latest ASTM standard for Phase 1 ESA’s: Standard Practice for Environmental Site Assessments: Phase 1 Environmental Site Assessment Process, and expands on each of the four ASTM-defined Phase 1 ESA components:

  • Records Review,
  • Site Reconnaissance,
  • Interviews, and
  • Reporting.

The three principals of CES are members of the E-50 Task Force Committees that revise the ASTM standards.  Since CES is involved in the standard making process, we are in the best position to provide sound technical and administrative direction and guidance to our clients.  Our professional staff, dedicated to performing and reviewing our Environmental Site Assessments, include registered Professional Geologists (PGs), Environmental Professionals (EPs), Registered Environmental Assessors (REAs), and AHERA Building Inspector/Management Planners.

CES also conducts our own research when providing Federal, Tribal, State and Local Government Environmental Data using ASTM specified parameters and search radii.  CES has found that utilizing third party sources for environmental database information has been historically unreliable, and utilizing databases provided to CES by the Arizona Department of Environmental Quality (ADEQ) and various other government agencies ensures that the most detailed information is being communicated to our clients.

Phase 1 ESA

CES has prepared thousands of Phase 1 ESAs for clients in Arizona, California, New York, Michigan, Texas, New Mexico, Colorado, Nevada, Utah and Canada.  Range of services included Phase 1 ESAs for vacant land up to complex industrial facilities.  Our clients have also used our recommendations to conduct Phase 2 Environmental Site Assessment sampling activities to further determine the environmental impacts to soil and water due to past practices in order to avoid costly delays or overruns in construction and development of commercial sites.
