2.3.2.2
Paint Chip Sample Preparation and Analysis
Paint chip samples shall be prepared for analysis following the ASTM Standard Practice for the
Preparation of Dried Paint Samples for Subsequent Lead Analysis by Atomic Spectrometry
(E 1645) or Standard Provisional Practice for Ultrasonic Extraction of Paint, Dust, Soil, and Air
Samples for Subsequent Determination of Lead (E 1979), and analyzed following the Standard
Test Method for Analysis of Digested Samples for Lead by Inductively Coupled Plasma Atomic
Emission Spectrometry (ICP-AES), Flame Atomic Absorption (FAAS), or Graphite Furnace
Atomic Absorption (GFAAS) Techniques (E 1613). The most current version of the methodology
shall be used. Results shall be reported in units of micrograms per gram (g/g) and parts per
million (ppm), allowing direct comparison with Table A-1, EPA, and HUD criteria.
2.3.2.3
Soil Sample Preparation and Analysis
Soil samples shall be prepared for analysis following the ASTM Standard Practice for Sample
Digestion of Soils for the Determination of Lead by Atomic Spectrometry (E 1726) or Standard
Provisional Practice for Ultrasonic Extraction of Paint, Dust, Soil, and Air Samples for
Subsequent Determination of Lead (E 1979) and analyzed following the Standard Test Method
for Analysis of Digested Samples for Lead by Inductively Coupled Plasma Atomic Emission
Spectrometry (ICP-AES), Flame Atomic Absorption (FAAS), or Graphite Furnace Atomic
Absorption (GFAAS) Techniques (E 1613). The most current version of the methodology shall
be used. Results shall be reported in units of g/g and ppm, allowing direct comparison with the
EPA criteria.
2.3.2.4
Laboratory Turnaround Time
The Contractor shall require the laboratory to report analytical results to the Contractor within
[Insert appropriate number of days] days of the laboratory's receipt of the samples in the
laboratory.
2.3.3
Quality Assurance and Quality Control (QA/QC)
2.3.3.1
XRF Performance Validation and Verification
The lead inspector/risk assessor shall use only XRF spectrum analyzers with current, published
Performance Characteristic (PCS) sheets that provide valid measurements at the Action Levels
specified in Table A-1. A copy of the PCS for the XRF instruments used on this project shall be
submitted in the Lead Inspection Sampling Plan section of the Lead Inspection/Risk Assessment
Report.
The lead inspector/risk assessor shall perform calibration checks at the beginning and
end of the inspection work or every four hours, whichever comes first or as otherwise specified
in Chapter 7 of the HUD Guidelines: "Guidelines for the Evaluation and Control of Le ad-Based
A-24
