Lead Based Paint Inspections
CORE was retained by the New York City Housing Authority to
perform a lead-based paint inspection of apartment units at many of
the developments located in the five (5) boroughs. Inspections were
performed by CORE Inspectors trained and certified in accordance with
40 CFR Part 745. The fieldwork associated with these inspections was
performed after residents moved out and was completed in one day, and
the final report was provided within five days.
The intent of the inspections was to ascertain if the surface coatings on
building components have a lead concentration greater than or equal
to 1.0 mg/cm2 or 0.5 percent by weight. The inspections were typically
seven (7) to eleven (11) rooms. Approximately 100 to 150 measurements
by X-Ray Fluorescence (XRF) analysis were completed in each unit. In
addition, paint chip samples and lead dust wipe samples were collected
and analyzed as needed.
The primary lead detection technique utilized for this work is XRF
Analysis. The XRF analysis is conducted on site, using a portable LPA-1
Lead Paint Inspection System manufactured by Radiation Monitoring
Devices, Inc. (RMD). The LPA-1 was utilized in accordance with the
Instrument Performance Characteristic Sheet (PCS), and Chapter 7,
October 1997 revision, of the HUD Guidelines for the Evaluation and
Control of Lead Based Paint Hazards in Housing. The XRF K-Shell
readings are categorized as positive or negative for lead-based paint by
using the thresholds as identified in the PCS.
