Radon
Screening
An ESA
is conducted on a parcel of property to determine if environmental
contamination exists. An ESA is typically required by a financial
institution prior to providing financing for a particular piece of
property. ESAs may protect the future property owner and financial
institution from liability if the previous owners contaminated the
property.
ET performs
ESAs in a phased approach (Phase I & II) to limit the initial cost
to our clients. Phase I ESAs are conducted according to the American
Society for Testing and Materials (ASTM) standard. ESAs may also be
conducted as a Transaction Screen following a condensed ASTM reporting
protocol. Both rely on the collection of non-intrusive, historical
information. The intent of a Transaction Screen is to provide a more
cost-effective means of assessing properties that are deemed to require
less historical review. These properties may include undeveloped lots,
residences or recently developed parcels. Transaction Screens involve
a site walk-through and interview to check the property and surrounding
properties for environmental concerns. During the walk-through, a
site checklist is completed summarizing current and past site conditions.
The site walk-through and interview are conducted in the presence
of a person or persons knowledgeable about the current and past conditions
of the property.
A Phase
I report is compiled for properties that are suspected of potentially
having environmental concerns. Transaction Screens are intended to
provide a cost-effective means of assessing a property with a low
likelihood of environmental concern whereas Phase I Reports are intended
to provide a comprehensive historical review for purposes of reducing
liability risks associated with historical property usage. We perform
a thorough investigation to determine the property's history using
aerial photographs, Sanborn fire maps and EPA records. A field reconnaissance
is also conducted to inspect the property and/or building(s) for the
possibility of petroleum contamination, asbestos, lead, Polychlorinated
biphenyls (PCBs), radon and other environmental concerns. A report
is compiled detailing any environmental hazards that are suspected
to be present.
As a
Phase I assesses the potential for property contamination, a Phase
II may be required to confirm or deny suspected contamination to the
site. The Phase II consists of collecting samples from areas that
are suspected to contain hazardous materials or substances, thereby
providing conclusive results as to whether an environmental hazard
exists and if so, to what extent. A Phase II report is compiled outlining
any environmental hazards associated with the property so the prospective
buyer and financial institution understand the associated risks.
