ESA & Investigations

Brinkerhoff Environmental Services, Inc. performs Due Diligence inspections and investigations of real property for Clients entering into to real estate acquisition, mergers and loan transactions. Brinkerhoff provides our Clients with information, recommendations, and options to meet their objectives, and is dedicated to providing technical excellence at competitive rates.

Brinkerhoff prepares Phase I Environmental Site Assessments (ESAs), which exceed recognized ASTM standards (E1527-00). Our approach includes the following:

  • Preliminary Assessment/Site Investigation
  • Ecological Assessment Natural Resource Damages (NRD)
  • Underground Storage Tank (UST) Management
  • Lead-based Paint, Asbestos, and Hazardous Materials Investigation
  • Historic Fill Assessment
  • Building Condition Evaluation


Upon completion of an assessment to determine ISRA applicability, Brinkerhoff prepares recommendations on cost-effective options for bringing a property into viability for reuse or sale. If active remediation is necessary, Brinkerhoff directs labor and equipment to install various treatment systems. Examples include: multi-phase extraction systems for removal of gasoline, diesel and fuel oil products; air stripping units for removal of volatile organic substances, including petroleum-based solvents; and, air sparge and vacuum extraction systems for volatilizing and venting chemical substances.


Brinkerhoff assists property owners and responsible parties with evaluating the environmental impact of contamination and NRD. Such resources include groundwater, wetlands, and habitats of endangered species.


Brinkerhoff directs waste management, disposal of regulated substances, waste manifestation and selection of disposal facilities to minimize costs and avoid future litigation and regulatory fines. Our services include state and local agency coordination, preparation of reports as required for regulatory compliance, waste management (hazardous and non-hazardous), and project closeout-cost accounting.


Brinkerhoff provides geophysical scanning services to locate drums, underground storage tanks, foundations, septic systems, abandoned mine shafts, utilities and other buried objects to depths of 25 feet and greater. Our innovative technologies are state-of-the art and provide clear data with consistent results.

The Magnetic and Ground-Penetrating Radar (GPR) systems we use deliver instantaneous, real time data, displayed on a computer in the field. Scanned data can be checked from a variety of approach directions to verify the type of subsurface anomalies encountered. When necessary, suspect areas can be rescanned in the field with higher accuracy.

Field data are tied to satellite global positioning systems (GPS) for location accuracy. This information may easily be used to relocate anomalies at a later date when construction, demolition or drilling activities are underway.   Data can be electronically transmitted from the field to the office for further evaluation. Data printouts and displays provide graphic results in 2-D & 3-D that can be easily interpreted and reviewed. The data can also be inverted and rotated for various views of subsurface conditions.
