Environmental Due Diligence

Remediation of crude oil from the aquifer is difficult, owing to sorption and entrapment of the oil in the pore spaces within sediments. Consequently, the oil-phase recovery was limited and considerable volumes of mobile and entrapped oil remain in the subsurface despite the remediation effort.

The simple, cost-efficient monitoring methods used in this study, which included measuring oil thicknesses in wells and dissolved oxygen concentrations in groundwater, provided an inexpensive approach to evaluating the efficacy of the remediation. In 2003, it was estimated that the United States has more than 240,000 kilometers (km) of oil pipeline. In 2011, the total amount of oil released annually was estimated at about 111,000 liters per 1,600 km of pipeline. Developing effective approaches for managing and remediating crude oil spills remains an essential precaution.

Phase I Environmental Site Assessment

Phase I Environmental Site Assessments (Phase I ESA) are the central product in ERGON-GSP's Environmental Due Diligence practice. Phase I ESAs are our core environmental expertise. ERGON-GSP fully understands how the Phase I Environmental Site Assessment Report is used in the commercial and multi-family real estate industry. ERGON-GSP provides Phase I ESA reports throughout the United States, Canada, Mexico and Europe for U.S. based commercial real estate lenders and those based outside of the U.S.

A Phase I Environmental Site Assessment is the gold standard for evaluating the environmental liability associated with a real estate asset of any type. Whether the property is industrial, commercial, mixed-use, multifamily, ERGON-GSP is able to fully assess the historical and current uses of the property. ERGON-GSP is truly an expert at the implementation of the ASTM E1527-13 Standard. Our Phase I Environmental Site Assessments are done by Environmental Professionals who meet the requirements of the EPA's AAI Standard.

Our experience in Phase I Environmental Site Assessments dates back to before the creation of the ASTM Standards. Having performed Phase I ESAs on hundreds of thousands of properties, we offer our clients an expert perspective on every property type.


ASTM E1527-13 Standard Update

On November 6th, 2013, ASTM published the long anticipated new standard for conducting Phase I Environmental Site Assessments, ASTM E1527-13. ASTM E1527-13 will take effect immediately and will replace the E1527-05 standard as the industry best practice for Phase I ESAs. The most significant changes include:

  • File Reviews - The E1527-13 standard imposes a stronger imperative for conducting regulatory file reviews.
  • Vapor Migration - E1527-13 places greater emphasis on assessing impacts to the subject property from vapor migration.
