INTRODUCTION: This laboratory was inspected to verify its compliance with the requirements of 15A NCAC 2H .0800 for the analysis of environmental samples. II. GENERAL COMMENTS: This was the first inspection for this facility. The lab was very clean and well organized. All equipment necessary to perform the certified parameters were present and appeared well maintained. A description of current field lab policies and technical assistance documents for the analysis of the facility’s currently certified parameters were provided at the time of the inspection. The facility is certified for Dissolved Oxygen and Temperature; however, reporting of these parameters is not required by their permit. III. FINDINGS, REQUIREMENTS, COMMENTS AND RECOMMENDATIONS: pH – Standard Methods, 20th Edition, 4500 H+ B Comment: The facility is currently documenting a “duplicate” sample analysis for pH. The pH analysis is being performed in-situ, which would not allow for a true duplicate. In addition, duplicate analysis of pH samples is not required for Field Labs. Settleable Solids – Standard Methods, 20th Edition, 2540 F A. Finding: The sample collection time is not being documented. Requirement: 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. Ref: 15A NCAC 2H .0805 (g) (1). Page 2 #5572 Camden County Wastewater Treatment Plant Documentation B. Finding: Error corrections are not being done in an approved manner. Requirement: All documentation errors must be corrected by drawing a single line through the error so that the original entry remains legible. Entries shall not be obliterated by erasures or markings. Wite-Out®, correction tape or similar products designed to obliterate documentation are not to be used. Write the correction adjacent to the error. The correction must be initialed by the responsible individual and the date of change documented. All data and log entries must be written in indelible ink. Pencil entries are not acceptable. Ref: North Carolina W astewater/Groundwater Laboratory Certification document, Quality Assurance Policies for Field Laboratories. C. Finding: Preparation and/or purchase of standards, reagents and consumables are not being documented in such a way as to provide traceability. Requirement: 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 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. Ref: North Carolina W astewater/ Groundwater Laboratory Certification document, Quality Assurance Policies for Field Laboratories. D. Finding: The sample collection sites are not being documented on the benchsheets. Requirement: 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 bench sheets must provide a space for the signature or initials of the analyst, and proper units of measure for all analyses. Ref: 15A NCAC 02H .0805 (g) (1). E. Finding: The proper units of measure are not being documented on the benchsheets. Requirement: 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 bench sheets must provide a space for the signature or initials of the analyst, and proper units of measure for all analyses. Ref: 15A NCAC 02H .0805 (g) (1). IV. PAPER TRAIL INVESTIGATION: The paper trail consisted of comparing field testing records and contract lab reports to Discharge Monitoring Reports (DMRs) submitted to the North Carolina Division of Water Quality. Data were reviewed for permit # WQ0029894 for October, November and December, 2009. The following errors were detected: Page 2 #5572 Camden County Wastewater Treatment Plant The monitoring report column headings for TOC, Chloride, TDS, Nitrate and Turbidity did not contain any concentration units. Results reported as less than the detection limit are not being treated as zero when calculating the arithmetic mean. In addition to those stated above, the following transcription error was noted: Date Parameter Location Value on Benchsheet Value on DMR 12/02/09 pH Effluent 6.7 S.U. 6.4 S.U. In order to avoid questions of legality, it is recommended that you contact the appropriate Regional Office for guidance as to whether an amended Monitoring Reports will be required. A copy of this report will be forwarded to the Regional Office. V. CONCLUSIONS: Correcting the above-cited findings will help this lab to produce quality data and meet certification requirements. The inspector would like to thank the staff for its honesty and assistance during the inspection and subsequent data discovery and review process. Please respond to all findings.
