Environmental Laboratory Accreditation Proficiency Test Study Requirements [36 Pa.B. 1181] In accordance with 25 Pa. Code Chapter 252, Subchapter E (relating to proficiency test study requirements), the Department of Environmental Protection (Department) is providing the following tables which list the fields of accreditation for which proficiency test studies are available. To obtain or maintain a field of accreditation, the Department requires that an environmental laboratory successfully participate in proficiency test studies when available. The following tables contain fields of accreditation for which proficiency test studies are available for nonpotable water (NPW), drinking water and solid and chemical materials. Environmental laboratories seeking initial accreditation must successfully complete a proficiency test study within 12 months prior to applying for initial accreditation or during the approval process. Environmental laboratories seeking to maintain accreditation must successfully complete a proficiency test study for each field of accreditation at least once every 12 months. Additional information regarding the proficiency test study requirements is contained in 25 Pa. Code Chapter 252, Subchapter E.
Updates to the following lists will be published in the Pennsylvania Bulletin as revisions are made. Questions concerning this notice, including the lists of proficiency testing currently available, should be directed to Aaren Alger, Department of Environmental Protection, Bureau of Laboratories, (717) 346-8212, aaalger@state.pa.us.
