CORE was retained by the New York City Housing Authority to perform Lead-Based Paint (LBP) Inspections of apartment units at various NYC Housing Developments located in the five (5) boroughs. The intent of the inspections was to provide Single Family Testing and LBP Inspections of dwelling units within multi-family dwellings, in accordance with 24 CRF Part 35.132(a).

Such testing and inspections consisted of the following:

  • Performing surface-by-surface Lead Inspections of an entire
  • Dwelling Unit following single family testing
  • Collecting confirmatory paint chip samples of painted/coated surfaces that test positive as LBP
  • Collecting pictures of damaged areas of LBP
  • Providing analysis of confirmatory paint chip samples
  • Providing downloaded testing data
  • Providing final reports

Hazardous Paint Condition Inspections included the following:

  • Identification and documentation of any mold/mildew conditions or leaks/moisture problems
  • Identification of paint conditions within each room
  • Identification and documentation of hazardous and paint conditions
  • Preparation and submission of complete applications for exemption from the Administrative Code 27-2056.5(a)
  • Timely mailing of lead-based paint notices to residents

The primary lead detection technique utilized for this work is XRF Analysis. The XRF analysis is conducted on site, using a portable Viken Detection Pb200i XRF Analyzer. The Pb200i was utilized in accordance with the Instrument Performance Characteristic Sheet (PCS), and Chapter 7, July 2012 revision, of the HUD Guidelines for the Evaluation and Control of Lead Based Paint Hazards in Housing. XRF results are classified as positive if they are greater than or equal to the stated threshold for the instrument (1.0 mg/cm2), and negative if they are less than the threshold.
