Lead Hazard Services

Lead Risk Assessment

services-leadhazard1Assessing the risk of lead in buildings will be done in accordance with the Department of Housing and Urban Development’s Guidance for the Evaluation and Control of Lead Based Paint Hazards in Housing and all applicable Federal, State and Local Guidelines.

Lead Based Paint Testing

The testing for Lead Based Paint is accomplished by :

  1. Paint Chip Sampling and tested in a lab by Atomic Absorption Spectrometry (AAS)
  2. Testing for Lead in Paint using an X-Ray Fluorescence (XRF) Lead in Paint Spectrum Analyzer.

To test for Lead in paint, Westchester Environmental will provide a competent Lead Inspector Risk Assessor. We can also test for lead in soil, water and air in accordance with US regulatory agencies standards.

Lead Abatement Monitoring and Testing

Our scope of work for lead abatement monitoring shall include, at a minimum, the following:

  • Providing a competent Lead Inspector Risk Assessor.
  • Inspectors will ensure standard and acceptable operating procedures, engineering control systems, respiratory protection, decontamination procedures, disposal of waste and any other aspects of the project that might affect the health and safety of the building occupants and the environment.
  • Collect baseline samples prior to initiation of each work activity or abatement area.
  • During abatement our technician will collect wipe samples at critical barriers, and other locations outside of the work area when visible dust is detected. If levels are above background levels, the area shall be deemed contaminated.
  • If at any time during the course of the work, airborne lead concentrations exceed the background concentrations or the EPA limits outside the work area, the Technician will request the Contractor to halt all lead abatement activities and take corrective measures. Work may not commence until the source of the contamination has been identified, and additional air and wipe samples have been collected and analyzed indicating acceptable lead concentrations.
  • After a thorough and final cleaning of the work area, the Contractor will notify our firm for a Final Visual Inspection. If work area is visually clean, we will perform subsequent Final Clearance Testing. A Lead Certification of Visual Inspection will be issued on satisfaction of the clearance criteria.
Lead Final Clearance Testing

services-leadhazard2After lead based paint stabilization and/or abatement, lead Final Clearance Testing will be conducted via wipe sampling in accordance with the Department of Housing and Urban Development’s Guidance for the Evaluation and Control of Lead Based Paint Hazards in Housing.

When applicable, soil samples will be collected in addition to wipe samples to satisfy clearance criteria. Wipe and soil samples will be analyzed via EPA SW-846 method 7420.
