Box 429 Kings Mountain, NC 28086 SUBJECT: North Carolina Wastewater/Groundwater Laboratory Certification (NC WW/GW LC) Initial Inspection Dear Mr. Henson: Dee Freeman Secretary Enclosed is a report for the inspection performed on July 21, 2011 by Chet Whiting. I apologize for the delay in getting this report to you. Since the finding(s) cited during the inspection were all corrected prior to the completion of the enclosed report, a response is not required. The staff is commended for taking the initiative in correcting the findings in such a timely manner. For certification maintenance, your laboratory must continue to carry out the requirements set forth in 15A NCAC 2H .0800. Copies of the checklists completed during the inspection may be requested from this office. Thank you for your cooperation during the inspection. If you wish to obtain an electronic copy of this report by email, or if you have questions or need additional information please contact me at 828-296-4677.

Ellison WTP NC0079740 P.O. Box 429 Kings Mountain, NC 28086 5597 July 21, 2011 Field Initial Chet Whiting Newt Henson This laboratory was inspected to verify its compliance with the requirements of 15A NCAC 2H .0800 for the analysis of environmental samples. The Laboratory is not currently analyzing samples that fall under the scope of this program. Facility personnel expressed a desire to have their systems for analysis and documentation compliant with Certification requirements prior to beginning testing. Their proactive attitude is appreciated. The lab had developed a good pH meter calibration sheet. Documentation: Comment: The laboratory did not have an adequate system of documentation for analytical and supporting data as required by Certification Rules. The North Carolina Administrative Code, 15A NCAC 2H .0805 (g) (1) states: Data pertinent to each analysis must be maintained for five years. Certified Data must consist of date collected, time collected, sample site, sample collector, and sample analysis time. The field benchsheets must provide a space for the signature or initials of the analyst, and proper units of measure for all analyses. An example bench sheet was provided to the lab by e-mail July 25, 2011. Notification of acceptable corrective action (i.e. acknowledgement of implementation of a benchsheet that documents all required information) was received by electronic mail on 8/31/2011. No further response is necessary for this finding. Comment: The laboratory needed to increase the documentation of materials and reagents. The Quality Assurance Policies for Field Laboratories document states: All chemicals, reagents, standards and consumables used by the laboratory must have the following information documented: Date Received, Date Opened (in use), Vendor, Lot Number, and Expiration Date. A system (e.g., traceable identifiers) must be in place that links standard/reagent preparation information to analytical batches in which the solutions are used. Documentation of solution preparation must include the analyst's initials, date of preparation, the volume or weight of standard(s) used, the solvent and final volume of the Page 2 #5597 City of Kings Mountain T.J. Ellison WTP solution. This information as well as the vendor, manufacturer, lot number, and expiration date must be retained for chemicals, reagents, standards and consumables used for a period of five years. Consumable materials such as pH buffers and lots of pre -made standards are included in this requirement. Notification of acceptable corrective action (i.e., implementing the use of a new benchsheet that includes consumable traceability) was received by electronic mail on 9/15/2011. No further response is necessary for this finding. pH — Standard Methods, 18th Edition, 4500 H+ B Comment: The temperature sensing device on the pH meter had been calibrated against an NIST certified thermometer; however the corrections were not posted. Technical Assistance for Field Analysis of pH states: All temperature sensing devices on meters must be calibrated against a NIST certified or NIST traceable thermometer annually (every 12 months) and proper corrections made and documented. The meter reading must be less than 1°C from the NIST certified reading to be acceptable. Document the serial number and manufacturer of the NIST thermometer that was used in the comparison. Document any correction that applies (even if zero) on both the meter and on a separate sheet to be filed. Notification of acceptable corrective action (i.e. a copy of the temperature sensor calibration from Laboratory Instrument Service and a statement indicating the correction was posted on the meter) was received by electronic mail on 9/13/20i 1 and 9/ 1/2G 11. No further response is necessary for this finding. Total Residual Chlorine — Standard Methods, 18th Edition, 4500 CI G Comment: The instrument's factory calibration curve had not been verified. The Technical Assistance for Field Analysis of Total Residual Chlorine states: Analyze water blank to zero the instrument and then analyze a series of five standards. The curve verification must check 5 concentrations (not counting the blank) that bracket the range of the samples to be analyzed. This type of curve verification must be performed at least every 12 months. The values obtained must not vary by more than 10% of the known value for standard concentrations greater than or equal to 50 tag/L and must not vary by more than 25% of the known value for standard concentrations less than 50 pg/L. The overall correlation coefficient of the curve must be >_0.995. Notification of acceptable corrective action (i.e. a statement acknowledging implementation of acceptable curve verification from 8/25/2011) was received by electronic mail on 9/15/2011 No further response is necessary for this finding. Comment: The true value of the gel standard used to check the calibration of the meter prior to analysis was not verified. The Technical Assistance for Field Analysis of Total Residual Chlorine states: Purchased Gel -type or sealed liquid ampoule standards may be used for daily calibration verification only. These standards must be verified initially and every 12 months thereafter, with the standard curve. Notification of acceptable corrective action (i.e. the established true value, 191 ,ug/L, and the acceptance criteria, 172 to 210 Ng/L, of the gel standard) was received by electronic mail on 9/15/2011. No further response is necessary for this finding. Total Residual Chlorine — Standard Methods, 181h Edition, 4500 CI G pH — Standard Methods, 181h Edition, 4500 H+ B Comment: There was no system in place to document Proficiency Testing (PT) samples in the same manner as routine environmental samples. Quality Assurance Policies for Field Laboratories states: The analysis of PT samples is designed to evaluate the entire process used to routinely report environmental analytical results; therefore, PT samples must be analyzed and the process documented in the same manner as environmental samples. Notification of acceptable corrective action (i.e. acknowledging implementation of a benchsheet that documents pertinent information) was received by electronic mail on 9/15/2011. No further response is necessary for this finding. Page 3 #5597 City of Kings Mountain T.J. Ellison WTP IV. PAPER TRAIL INVESTIGATION: No paper trail was conducted. All findings noted during the inspection were adequately addressed prior to the completion of this report. The inspector would like to thank the staff for its assistance during the inspection and data review process. No response is required.
