1. DOW Laboratory Certification Program Update – 2013 Presentation to: KWWOA April 17, 2013 Department for Environmental Protection Energy & Environment Cabinet To Protect and Enhance Kentucky’s Environment

2. Topics Program Update Microbiology Update Common Audit Findings Summary 2

3. Drinking Water Program Update ProgramIn-stateOut-of-state Chemistry Labs 1536 Microbiology Labs452 Cryptosporidium20 Radionuclides09 Dioxin06 Asbestos13 PCBs (EPA508A)02 3

4. Certificate + Analyte-Method List Certificates are valid January 1 st – December 31 st of each calendar year Only one certificate for laboratories with both Chemistry and Microbiology certification Both Chemistry and Microbiology certificate packages include an analyte-method list Analyte-method lists must include Minimum Reporting Limit (MRL) 4

5. Compliance Sample Results DOW continues using SDWIS filters which will reject any results (analyte-method) that a certified laboratory is not certified for – this includes secondary contaminants SDWIS filters also include the KY MRL – any laboratory non-detect result not meeting the MRL is flagged by the database MRL must be < Required Reporting Limit 5

6. On-site Laboratory Audits Both Chemistry and Microbiology laboratories will be audited at least twice every three years Cryptosporidium audits have been completed for 2013. Laboratories will be audited at least once during upcoming LT2 monitoring (2015) Announced and Unannounced Audits 6

7. Upcoming Cryptosporidium LT2 All previously certified Cryptosporidium certified laboratories must recertify for 2015 Check USEPA website for a list of currently certified Cryptosporidium laboratories Contact DOW if you have any questions regarding Cryptosporidium certification 7

8. Laboratory Accountability Program DOW will continue to utilize the Laboratory Accountability Program for laboratory reporting errors that are submitted to the state Laboratory Accountability Program has contributed to the reduction of the number of violations issued to public water systems 8

9. Proficiency Test Studies Laboratories performing drinking water analyses are required to successfully complete one PT Study per analyte-method each year Laboratories that fail two consecutive PT Study samples for the same contaminant must report to the state with a corrective action plan DOW is pursuing electronic tracking of all PT Study results – in place by end of 2013 9

10. Technical Assistance Updated list of certified laboratories Updated method – analyte code list DOC Worksheet (IDC, MDL & RLS) Control Charts – worksheet template Contact DOW with any ideas for future technical assistance tools 10

11. 11 DOW Laboratory Audit Team Frank Hall – Certification Program Manager Patrick Garrity – Laboratory Certification Officer Kevin Stewart – Certification Officer Arianna Lageman – Certification Officer Dr. Ted Pass – Certification Officer Tiffany Nolan – Laboratory Auditor Erich Cleaver – Laboratory Auditor

12. Microbiology Program Update Dr. Pass and Ms. Rita Wright are no longer associated with Morehead State University (MSU) DOW stills utilizes MSU as State Principle Microbiology Laboratory Dr. Pass is a contract employee with DOW Ms. Rita Wright is affiliated with Fouser Environmental Services (Versailles, KY) 12

13. Microbiology Program Update DOW has established: –Initial Requirements for a Drinking Water Microbiology Laboratory –Microbiology Analyst Approval Process DOW does not track CEUs – laboratories are required to maintain all training records for review during on-site audit or upon request 13

14. Commonly Found Audit Findings General Findings Chemistry Microbiology 14

15. General Audit Findings KY regs capture SM 18 th, 19 th, 20 th & 21 st Ed. All methods must be performed as written, including all quality control criteria Use of Standard Methods must include QC criteria from Chapters 1020, 2020, 3020, etc. Maintain sample integrity at all times –Chain of Custody must be complete/signed –Internal laboratory sample tracking record 15

16. General Audit Findings (cont) Traceable back to NIST – whenever possible –Eppendorf Pipets, Thermometers, Balances, Standards, Reagents, etc. Utilize control charts (trend analysis) or document quality control acceptance limits Notify DOW of key personnel changes Utilize maintenance log books for instruments Remember – document all observations! 16

17. Chemistry Laboratory Audit Summary Methods used must be published in 40CFR141 or an EPA signed ATP on file at laboratory Method must be capable of meeting KY MRL Laboratory must demonstrate KY MRLs (e.g. reporting limit standard) MDLs – annually (2-3 non-consecutive days) IDC – performed by each analyst initially ODC – performed by each analyst annually 17

18. Chemistry Audit Findings (cont) All drinking water methods must be performed as written in the EPA approved method All quality control samples must have an acceptance criteria and associated corrective action for unacceptable results Documentation of preservation checks (VOCs) Fluoride probe must be placed in sample before stirring begins – to reduce air bubbles 18

19. Microbiology Laboratory Audit Summary Perform EPA approved methods as written Colilert-18 and 24 are treated as two methods PT Studies – in accordance with EPA Manual Colilert-18 for Fecal Coliform – must receive written approval from EPA Region 4 Use bench sheets for analysis of PT Samples Replace reference comparators when expired Utilize internal sample tracking documents 19

20. Microbiology Audit Summary (cont) Supervisors and QA Managers must meet credential requirements listed in EPA Manual SOPs / QAMs must be reviewed/updated annually – document date BACT samples must be at least 100 mL DOC must be performed and documented Strikeouts/overwrites – single line, date/initial Analyst Signature/Initials must be on file 20

21. 21 Drinking Water Website Ongoing Improvements to the DOW website http://water.ky.gov/DrinkingWater/Pages/CertifiedLaboratories.aspx Laboratory Certification Webpage Updates: –Useful information and documentation –DOC worksheets (IDC, MDL & RLS) –Minimum Reporting Limits listed –List of KY analyte codes and method codes –Approved PT Study Providers
