Bovis Lend Lease, Inc. Environmental Hazard Investigation
75 Park Place February 22,2002
Floors 6, 7, 8, & 9 EHI Project #: 0224-0572A
1.0 Introduction
Environmental Health Investigations, Inc. conducted an investigation of Floors Six, Seven,
Eight and Nine at 75 Park Place, New York, New York. This investigation was a follow up to a
previous survey conducted on January 25 and 26,2002 (see EHI report 0224-0572 dated
February 4, 2002). The purpose of this foUow up evaluation was to determine whether any
hazard from inorganic metals, dioxins or dioxin like compounds existed on the floors.
The survey involved collection of settled and/or surfece particulate on each of the floors.
The collected particulate were submitted for analysis to PSC Analytical Services. The survey was
conducted on February 22, 2002 by William S. Kerbel, CIH.
2.0 Methods
Samples of settled particulate were collected by attaching a 37-milIimeter cassette filter to
an electric pump and vacuuming an area between one square foot and one square meter. These
samples were designated as “A” samples and were submitted to PSC Analytical Services for
Metal Scans via ICAP.
A second set of samples designated as “B” samples were collected in the same manner as
the “A” samples but in an adjacent area. The samples were submitted to PSC Analytical Services
for Mercury analysis via AA.
A third set of samples designated as “C” samples were collected in an area adjacent to the
cireas where the “A” and “B” samples were collected. These samples were collected by wiping a
sterile gauze pad containing Hexane over the surface area. A one square foot area was wiped.
The samples were submitted to PSC Analytical Services for analysis for Dioxins via GC/MS.
