Environmental Laboratory Accreditation Proficiency Test Study Requirements
[52 Pa.B. 3520]
[Saturday, June 18, 2022]In accordance with 25 Pa. Code § 252.501(a) (relating to proficiency test study requirements), the Department of Environmental Protection (Department) is providing the following list of fields of accreditation (FOA) and fields of proficiency testing (FoPT) for which proficiency test (PT) studies are available. To obtain or maintain an FOA, the Department requires that an environmental laboratory successfully participate in PT studies when available.
The following FoPT listing updates the previous listings published at 36 Pa.B. 8006 (December 30, 2006), 39 Pa.B. 1447 (March 21, 2009), 39 Pa.B. 2636 (May 23, 2009) and 42 Pa.B. 2331 (April 28, 2012). The new FoPT listings are effective immediately. Note that this listing of FoPTs includes additions to those previously printed on December 30, 2006, March 21, 2009, May 23, 2009, and April 28, 2012. Environmental laboratories seeking to maintain accreditation for an analyte that has been added to the tables by this notice must successfully complete a PT study for that analyte(s) by June 1, 2023. The new analytes are identified by an asterisk ''*'' after the analyte name.
Additionally, the Department has identified some analytes as multi-matrix analytes using the identifier ''DW/NPW'' in the ''Matrix'' column of the tables. Laboratories seeking to obtain or maintain accreditation for these analytes must successfully complete a PT in either the Drinking Water or Non-Potable Water matrix, as specified by the appropriate footnote for each analyte, to obtain or maintain accreditation in both matrices.
Environmental laboratories seeking initial accreditation or laboratories seeking to add FOAs to their current Scope of Accreditation must successfully complete a PT study before accreditation is granted. Accredited environmental laboratories must successfully complete at least one PT study for each FOA, where available, once every 12 months to maintain accreditation. Additional information regarding the proficiency test study requirements is in 25 Pa. Code Chapter 252, Subchapter E (relating to proficiency test study requirements).
Updates to the following additions will be published in the Pennsylvania Bulletin as revisions are made. Questions concerning this notice, including the lists of proficiency testing currently available, can be directed to Annmarie Beach, Bureau of Laboratories, anbeach@pa.gov, (717) 346-8212.

1) Laboratories analyzing qualitative sample sets for more than one method in a particular study shall obtain a unique ten-sample set for each method reported.
2) These limits are for quantitative methods using membrane filtration (MF) or pour-plate (PP) techniques.
3) These limits are for quantitative methods using most probable number (MPN) techniques.
4) Laboratories seeking or maintaining accreditation for DW TTHMs must meet PT requirements for all 4 TTHM FoPTs in the given study, by method.
5) Laboratories seeking or maintaining accreditation for DW HAA5 must meet PT requirements for 4 out of 5 HAA5 FoPTs in the given study, by method.
6) One sample in every study, containing one Aroclor, selected at random from among the Aroclors listed (1016, 1221, 1232, 1242, 1248, 1254 or 1260) for the analysis of PCBs as decachlorobiphenyl. Laboratories must analyze and report results for all Aroclors in an individual PT study. Incorrect identification or quantitation of one Aroclor will result in failure for the group.
7) Unless a fixed limit is specified, the acceptance limits for regulated volatiles are ±20% at ≥ 10ug/L or ±40% at < 10ug/L and ±40% for Vinyl Chloride.
8) Laboratories seeking to obtain or maintain accreditation for these analytes in the DW matrix must successfully perform a PT in the Non-Potable Water Matrix, also known as a WP study.
9) All FoPTs must meet the design, verification, homogeneity, stability, and acceptance limits described in 40 CFR Part 141, V3 of the TNI Standard, and the TNI FoPT Tables.
10) Laboratories seeking or maintaining accreditation for Gamma (Photon) Emitters must meet PT requirements for all Gamma Emitter analytes in the FoPT in a given PT study, by technology/method (Barium-133, Cesium-134, Cesium-137, Cobalt-60, Zinc-65).
11) Laboratories seeking or maintaining accreditation for Radioactive Cesium must meet PT requirements for both Radioactive Cesium analytes in the FoPT in a given PT study, by technology/method (Cesium-134, Cesium-137).
12) Laboratories seeking to obtain or maintain accreditation for these analytes in the NPW matrix must successfully perform a PT in the Drinking Water Matrix, also known as a WS study.
13) These 20 VOCs constitute the USEPA's Group 1 VOCs. Laboratories seeking or maintaining accreditation for Group 1 VOCs must analyze and report results for all 20 Group 1 VOCs in a given study. Not Acceptable results for ≥ 5 compounds results in a Failure for all 20 compounds.
14) n-Hexane Extractable Material (HEM) per solvent extraction followed by gravimetric or infrared spectrometric analysis (Oil & Grease).
15) non-Polar Extractable Material per solvent extraction and Silica Gel Treated (SGT) followed by gravimetric or infrared spectrometric analysis (Total Petroleum Hydrocarbons).
16) The Low Level Analytes are specifically intended for technologies/methods that can achieve the listed PTRL. Laboratories analyzing routine environmental samples using technologies/methods that can achieve the listed PTRLs must analyze the Low Level Analyte PT samples.
17) Laboratories seeking or maintaining accreditation for Vinyl Chloride must also seek or maintain accreditation for the Group 1 VOCs.
18) The ten-sample set which is provided to the participant laboratories shall contain bacteria that produces the following results when analyzed:
• Positive results for total coliforms, fecal coliforms and E. coli.
• Positive results for total coliforms and negative results for fecal coliforms and E. coli.
• Negative results for total coliforms, fecal coliforms and E. coli.
• These limits are for Presence-Absence only.
19) The ten-sample set shall be assigned lot numbers and randomly composed of samples as follows:
• Two to four samples containing an aerogenic strain of Escherichia which will ensure positive results for total coliforms, fecal coliforms and E. coli when analyzed by any of the USEPA approved methods.
• Two to four samples containing an aerogenic strain of Enterobacter species and/or other microorganism which will ensure positive results for total coliforms and negative results for the fecal coliforms and E. coli when analyzed by any of the USEPA approved methods.
• One or two samples containing Pseudomonas species and/or other microorganism which will ensure negative results for total coliforms, fecal coliforms and E. coli when analyzed by any of the USEPA approved methods.
• One or two samples which do not contain any microorganisms which ensure negative results for total coliforms, fecal coliforms and E. coli when analyzed by any of the USEPA approved methods.

LC50 = Concentration where 50% of the organisms do not survive
NOEC = No Observable Effects Concentration
IC25 = Concentration where there is 25% reduction in growth or reproduction
ON = Calculation based on Original Number or organisms used to start the test
