Phase II Environmental Site Assessments - Intrusive Studies
Phase II Environmental Site Assessments (Phase II ESAs)
are conducted when the results of the Phase I ESA indicate the potential for
on-site or off-site contamination. These comprehensive studies are performed to
verify Phase I findings and to identify the areal extent of contamination.
The Phase II ESA initially consists of an evaluation of the existing site
information, including regional geologic, hydrogeologic, and physical
characteristics, identification of the chemicals of concern, and an
identification of the source areas and the potentially affected media.
Laboratory results are evaluated to determine if the concentrations of chemicals
of concern are within applicable standards.
Since each property location is unique, Phase II sampling plans are individually
developed based on the property's particular characteristics. The sampling plan
ensures that sufficient and representative data is obtained in order to evaluate
the potential for contamination of the subsurface environment in the areas of
concern by regulated substances and/or petroleum products. Quality assurance
objectives and standard operating procedures are incorporated in the sampling
plan in order to assure the accuracy and maximize the representativeness of the
data collected.
GETCO, Inc. employs a variety of testing methods when conducting a Phase II
investigation. These testing methods range from geophysical surveys (to discover
buried metallic objects such as barrels or USTs) to the collection and
laboratory analyses of soil and water samples. Sampling of all potentially
affected media, including soil, sediment, surface water, ground water, bedrock,
soil gas and air, is then performed utilizing standard industry technologies
including the installation of soil borings and ground water monitoring wells,
and the use of various other sampling devices.
GETCO, Inc.'s assessment procedures are performed in accordance with recognized
ASTM protocols, Ohio Voluntary Action Program protocols, and/or United States
Environmental Protection Agency (USEPA) guidance documents, thereby assuring
accurate information with conclusions that are consistent with the appropriate
standards.
