[Option 1]
[The XRF data properly collected as part of the inspection phase of this assessment shall be used
to evaluate all deteriorated paint surfaces for the presence of lead. Deteriorated painted surfaces
that were not suitable for testing by XRF due to shape, or accessibility etc., or where
inconclusive XRF readings were generated during the inspection phase, shall be tested
destructively by paint chip sample collection. The paint chip samples shall be collected and
submitted in accordance with the laboratory's SOP for collecting paint chip samples to determine
lead loading per cc of surface area, and ASTM's Standard Practice for Field Collection of
Dried Paint Samples for Lead Determination by Atomic Spectrometry Techniques (E 1729).]
[Option 2]
[The lead inspector/risk assessor shall collect and preserve paint chip samples on all deteriorated
painted surfaces in accordance with ASTM's Standard Practice for Field Collection of Dried
Paint Samples for Lead Determination by Atomic Spectrometry Techniques (E 1729).]
2.2.5
Soil Sampling
Each composite sample shall include not less than two (2) and not more than ten (10) sub-
samples collected from distinct locations roughly equidistant from each other along an axis.
Sub-samples along drip lines shall generally be collected two to six feet from each other. In
other sampling locations such as play areas sub -samples shall be collected from roughly
equidistant locations along each leg of an X-shaped pattern. Sample collection shall be
conducted in accordance with the most current edition of Standard Practice for Field Collection
of Soil Samples for Lead Determination by Atomic Spectrometry Techniques, ASTM Standard
E 1727.
2.2.6
Sample Identification
Dust, paint, and soil samples shall be identified using unique sample numbers. Field and
laboratory blanks and spiked samples submitted to the laboratory for QA/QC purposes shall be
numbered in such a way that the sample identity will not be revealed to personnel conducting the
analysis.
2.2.7
Sample Chain-of-Custody
The Contractor shall follow a standard chain-of-custody protocol to ensure and document a
continuous record of sample possession from sample collection to receipt by the laboratory. The
Contractor shall complete and maintain chain-of-custody forms for each set of samples shipped
