Specifications include, but are not limited to: The selected laboratory shall analyze lead in dust wipe samples, within the turnaround time requested, using Flame Atomic Absorption, Graphite Furnace Atomic Absorption or Inductively Coupled Plasma Emission Spectrometry. Results shall be reported as a lead loading (micrograms per square foot or µg/ft²). The laboratory protocols and analytical apparatus will be sufficient to achieve the detection and reporting limits necessary for HUD lead abatement project dust-wipe clearance levels. Sample area sizes are provided on the chain-of-custody form. Single surface dust samples will be collected using approved media that meets ASTM E 1792 standards and non-sterile centrifuge tubes in conformance with EPA and HUD standards. Composite sampling will not be conducted. The Burlington Lead Program will procure its own sampling supplies/media if not included in the laboratory price. The laboratory shall email the results of testing to the Burlington Lead Program no later than 4:00 PM on the day they are due. Dust samples collected during risk assessments shall typically be submitted for analysis with a “5 day” turnaround. Clearance dust sampling wipes will require a 2-hour turnaround time (or fastest) for analysis; Burlington Lead Program will conduct 110 full clearances over a 3 year and 6 month period. Analysis of Lead in Soil The laboratory shall analyze soil samples using Flame Atomic Absorption, Graphite Furnace Atomic Absorption or Inductively Coupled Plasma Emission Spectrometry. Results shall be reported in parts per million (ppm) of lead. The laboratory shall utilize a minimum reporting limit of 10 ppm on all soil samples. Soil will be collected using composite sampling methods in conformance with EPA and HUD standards. The laboratory shall email the results of testing to the Burlington Lead Program no later than 4:00 PM on the day they are due. All soil samples submitted for analysis with a “5 day” turnaround. B. Analysis of Lead in Paint The laboratory shall analyze paint chip samples using Flame Atomic Absorption, Graphite Furnace Atomic Absorption or Inductively Coupled Plasma Emission Spectrometry. Results shall be reported in parts per million (ppm) of lead. The laboratory shall utilize a minimum reporting limit of 10 ppm on all paint chip samples. Paint chip samples will consist of at least one square inch of paint and will be free of any substrate. The laboratory shall email the results of testing to the Burlington Lead Program no later than 4:00 PM on the day they are due. All paint chip samples submitted for analysis with a “5 day” turnaround.
