Summary of Quarterly Operations (January - March) EPA Contract No. EP-W-09-028 AMEC Project No.: 6064120318 Introduction This quarterly report summarizes results from the Clean Air Status and Trends Network (CASTNET) quality assurance/quality control (QA/QC) program for data collected during first quarter 2013. The various QA/QC criteria and policies are documented in the CASTNET Quality Assurance Project Plan (QAPP; AMEC, 2012). The QAPP is comprehensive and includes standards and policies for all components of project operation from site selection through final data reporting. It is reviewed annually and updated as warranted. Quarterly Summary AMEC's analytical laboratory continued to pursue International Organization for Standardization (ISO)/International Electrotechnical Commission (IEC) 17025 accreditation by the American Association for Laboratory Accreditation (A2LA). On January 21-22, 2013, a certified assessor audited AMEC's Gainesville, FL analytical laboratory. Overall, the laboratory did well. The assessor was pleased with laboratory personnel, instruments and equipment, and the quality of the data produced. Findings were minor and related to documentation of procedures. The laboratory's response to the A2LA assessment findings was submitted to A2LA on February 22, 2013. AMEC's response included corrective actions and evidence of completion of the corrective actions. All findings were addressed. A2LA staff reviewed the response and requested additional information. As of the end of first quarter 2013, AMEC was working on the follow up response. AMEC's response was submitted to A2LA staff on April 8, 2013. The response was deemed complete and subsequently forwarded to the Accreditation Council for evaluation. AMEC received ISO/IEC 17025:2005 accreditation on April 19, 2013 for its defined chemical testing scope, including, but not limited to, CASTNET laboratory test procedures. Beginning with the February 2013 data submittal, trace-level gas data from the BVL130, IL site were included in the raw data submittal to EPA's Air Quality System (AQS). Beginning with the AMEC Project No.: 6064120318 1 AMEC Environment & Infrastructure, Inc. ------- EPA Contract No. EP-W-09-028 CASTNET Quality Assurance Report — First Quarter 2013 March 2013 data submittal, trace-level gas data from the BEL116, MD and HWF187, NY sites were included with the BVL130 data and submitted to AQS. During March 2013, AMEC received results from sample analyses for proficiency test (PT) study 101 for Rain and Soft Waters from the National Laboratory of Environmental Testing, a branch of the National Water Research Institute with Environment Canada that provides QA services. Overall, AMEC's laboratory was rated, "very good" for PT 101 analyses. The laboratory's analyses showed no bias. AMEC's 5-year median rating remained "Very Good." AMEC submitted a Notice of Key Personnel Change to EPA during March 2013, which was approved by EPA. W. Charles Greer will replace William Imbur as the CASTNET QA Supervisor. Table 1 lists the quarters of data that were validated to Level 3 during first quarter 2013 by site calibration group. Table 2 lists the sites in each calibration group along with the calibration schedule. Table 3 presents the measurement criteria for continuous field measurements. These criteria apply to the instrument challenges performed during site calibrations. Table 4 presents the measurement criteria for laboratory filter pack measurements. These criteria apply to the QC samples listed in the following section of this report. Table 5 presents the critical criteria for ozone monitoring at sites that are configured to meet EPA's AQS criteria for QA/QC procedures and are operated in accordance with Part 58 of Title 40 of the Code of Federal Regulations (EPA, 2010). Table 6 presents the critical criteria for AQS-protocol trace-level gas monitoring. Quality Control Analysis Count The QC sample statistics presented in this report are for reference standards (RF) and continuing calibration verification spikes (CCV) used to assess accuracy and for replicate sample analyses (RP) used to assess "in-run" precision. In addition, laboratory method blanks (MB) containing reagents without a filter; laboratory blanks (LB) containing reagents and a new, unexposed filter; and field blanks (FB) containing reagents and an unexposed filter that was loaded into a filter pack assembly and shipped to and from the monitoring site while remaining in sealed packaging are also included. Table 7 presents the number of analyses in each category that were performed during first quarter 2013. Sample Receipt Statistics Ninety-five percent of field samples from EPA-sponsored sites must be received by the CASTNET laboratory in Gainesville, FL no later than 14 days after removal from the sampling tower. Table 8 presents the relevant sample receipt statistics for first quarter 2013. AMEC Project No.: 6064120318 2 AMEC Environment & Infrastructure, Inc. ------- EPA Contract No. EP-W-09-028 CASTNET Quality Assurance Report — First Quarter 2013 Data Quality Indicator (DQI) Results Figures 1 through 3 present the results of RF, CCV, and RP QC sample analyses for first quarter 2013. All results were within the criteria listed in Table 4. Table 9 presents summary statistics of critical criteria measurements at AQS-protocol ozone sites collected during the quarter. All data associated with QC checks that fail to meet the criteria listed in Table 5 will be invalidated. Results in shaded cells either exceed documented criteria or are otherwise notable. Table 10 presents observations associated with the shaded cell results in Table 9. Table 11 presents summary statistics of critical criteria measurements collected during the quarter for the AQS-protocol trace-level gas monitoring sites. All data associated with QC checks that fail to meet the criteria listed in Table 6 will be invalidated. Results in shaded cells either exceed documented criteria or are otherwise notable. Table 12 presents observations associated with the shaded cell results in Table 11. Laboratory Control Sample Analysis The laboratory control sample (LCS) is a reagent blank spiked with the target analytes from the established analytical methods and carried through the same extraction process that field samples must undergo. The LCS is not required by the CASTNET QA/QC program. LCS analyses are performed by the laboratory to monitor for potential sample handling artifacts and provide a means to identify possible analyte loss from extraction to extraction. The current action limits for LCS recovery are 80 percent and 120 percent. Figure 4 presents LCS analysis results for first quarter 2013. All recovery values were between 95 percent and 110 percent with the exception of a single Teflon filter nitrate result at 119 percent. Investigation did not reveal the cause of this higher recovery. Blank Results Figures 5 through 7 present the results of MB, LB, and FB QC sample analyses for first quarter 2013. All results were within criteria (two times the reporting limit) listed in Table 4. Suspect/Invalid Filter Pack Samples Filter pack samples that were flagged as suspect or invalid during first quarter 2013 are listed in Table 13. This table includes associated site identification and a brief description of the reason the sample was flagged. During first quarter, 10 filter pack samples were invalidated. Field Problem Count Table 14 presents counts of field problems affecting continuous data collection for more than one day during first quarter 2013. The problem counts are sorted by a 30-, 60-, or 90- day time period to resolution. A category for unresolved problems is also included. Time to resolution indicates the period taken to implement corrective action.
