EP 1110-1-28
31 Aug 01
Samples collected by the risk assessor during the assessment(s) shall be sent to a laboratory recognized
by the EPA under the NLLAP for analysis. The laboratory must be accredited for each type of analysis
required. The Contractor shall verify the following with the laboratory:
2.3.1.1
Dust Sample Preparation and Analysis
Dust samples shall be prepared for analysis following the ASTM Practice for Hot Plate Digestion of
Dust Wipe Samples for the Determination of Lead by Atomic Spectrometry (E 1644) 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. The laboratory shall report results in units of microgram per square foot (g/ft2), allowing direct
comparison with Table A-1 and EPA criteria.
2.3.1.2
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 the EPA criteria.
2.3.1.3
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 Det ermination 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.
2.3.1.4
Laboratory Turnaround Time
The Contractor shall require the laboratory to report analytical results to the Contractor within [5]
[insert number of days] days of the laboratory's receipt of the samples in the laboratory.
