  • Description:
    The results of round 14 of the Environmental Lead Proficiency Analytical Testing (ELPAT) program were discussed. ELPAT was a program to evaluate and improve the performance of laboratories performing analyses associated with lead (7439921) abatement. The program was part of the National Lead Laboratory Accreditation Project, an EPA sponsored program for accrediting private and state laboratories. Proficiency test samples for the participating laboratories were prepared using paint chips, dust wipes, and soils. Four samples of each matrix were prepared. The samples were sent out each calendar quarter (round). Laboratories were rated based upon their performance in the ELPAT program over the past year (four rounds) for each lead matrix. A laboratory was rated as proficient if all four samples were reported and were designated as acceptable for the last two consecutive rounds or at least 75% of the results reported in the last consecutive rounds were judged acceptable. A total of 416 laboratories participated in round 14, the samples for which were sent out in February 1996. Flameless atomic absorption and inductively coupled plasma atomic emission spectrometry were the predominant analytical methods used. The percentage of failures (outliers) in the results reported by the laboratories for the three sample matrices was: paint chips 3.7 to 5.9%, soils 4.6 to 9.3%, and dust wipes 4.9 to 7.2%. Of the 376 laboratories that reported results for the four paint chip samples, 354 to 362 were judged acceptable; 294 to 309 of the 324 that reported results for the soil samples and 324 to 332 of those that reported results for the dust wipe samples were judged to be acceptable.
