1. OPTIMISING CHEMICAL ANALYSIS FOR THE WFD BY QUALITY ASSURANCE PROCEDURES & ACCREDITATION An Overview OPTIMISING CHEMICAL ANALYSIS FOR THE WFD BY QUALITY ASSURANCE PROCEDURES & ACCREDITATION An Overview Michael Jackman, Chemical Expert Module 2: Water Budget, Pressures and Impacts, Significant Water Management Issues, Monitoring, Characterization Report

2. Objectives To ensure the National Information is optimised for the WFD the data must be correct. To achieve this there must be satisfactory laboratory quality assurance procedures in place

3. Laboratory Accreditation To ensure the laboratories results are credible, ideally the laboratory should be optimum quality assurance which are outlined in accreditation procedures. Accreditation can be: National, International EN ISO/IEC 17025:2005, Good Laboratory Practice GLP Organization for Economic Cooperation and Development (OECD) This consists of many components and are formally defined in the Quality Manual.

4. QA Manual The QA Manual defines the quality assurance management procedures for: Staff Equipment, reagents & standards. Sampling Analysis Quality Control Data management Documentation & Reporting

5. Laboratory Staff Mission Statement of the Laboratory’s standard. Diagram of Staff Reporting Structure Staff Organisational Plan with their roles and responsibilities. Terms of reference for each staff member. Ensure confidentiality of results Analysts’ Training record and requirements. Independent Quality Control Manager Adequate Supervision of Staff Ensuring staff are competent in undertaking the analysis (Training Certificates)

6. Analytical Equipment Equipment maintenance plans, Calibration procedures Logs of performance and maintenance. Operational Manuals.

7. Standards & Reagents Stock standards should be certified. Quality Control Standards should be from a different source than the Calibration Standards All standards and reagents should have shelf life date – (Date Received & serial number) Stock Control system

8. Laboratory Analysis Record of Method Validation Methods’ specifications. Standard operating procedures (SOP) for each method. Use 3 working standards Record of: Date of analysis, Analyst Result AQC results Calculation Any relevant environmental conditions temperature, biological sterility

9. Sampling SOP for sampling procedure, transport & preservation of sample. Sampling Schedule Registration of the samples, submitted to the Laboratory- Chain of Custody. Record Condition of Sample

10. Analytical Quality Control SOP for Quality Control Internal & External AQC Method Validation Procedures Corrective and Protective Actions Audit Trails predetermined schedule All Administered by QC Manager

11. Document Control All management documents approved and signed by senior staff before issuing (Document changes must undergo the same procedure) (Laboratory Information Management Systems (LIMS))

12. Data Management Analysis of Data Procedures (LIMS) Traceable When mistakes should be crossed out and the correct value entered. Alterations should be signed Equivalent controls on the computer (LIMS)

13. Results Reports Clear & unambiguous Predefined certificate format including signature of manager. Specifying : Method Condition of and identification of the sample. Statement of compliance with appropriate National, EU standards Quality Control Results

14. Management should be regularly try to improve the quality of the results and systems by reviewing the : Quality of Analytical & AQC Results Audit Trail Results Customer feedback Staff feedback Assessments by external bodies

15. Thank you and good luck with establishing optimum quality assurance procedures
