Steps
Open EPA's National Lead Laboratory Accreditation Program (NLLAP) List at epa.gov/lead/national-lead-laboratory-accreditation-program-list
Filter the published table by state and by the sample matrix needed (separate Paint Chips / Soil / Dust Wipes columns) — not every accredited lab handles all three
Check the 'Commercial Availability' column, since some listed labs (certain public health department labs) are not open to outside commercial submissions
Note the lab's accrediting organization code (1=AIHA LAP, 2=A2LA, 3=PJLA, 4=ANAB/ACLASS, 5=IAS) before booking
Known gotchas
This is a static published list updated in monthly 'rounds', not a live queryable API — re-check before assuming a lab is still accredited
Some labs on the list explicitly show 'No' for commercial availability — filter these out for private-sector work
