1. QA/QC in Lab Performance Renu Joshi, Ph.D. CAEAL Assessor Certified by the National Quality Institute, Canada

2. Components influencing QA/QC Facilities Administration Standard Operating Procedures Personnel

3. Facilities and equipment Adequate space separation between incompatible activities condition of floors, walls, ceiling & benches adequate storage space availability of all necessary equipment and functioning properly air quality logs maintained

4. Sample history Sample bottles Sample transportation Holding time Handling & storage in the lab

5. Media quality control All SOPs available for preparation of various media Control stock cultures maintained with logs +ve and -ve cultures used to ensure that media are functioning properly non-selective medium used to evaluate selective media all media and reagents properly labeled and stored

6. Faecal coliforms on selective and non-selective media

7. Method quality control Method used is current, authorized and validated Method blanks to monitor contamination Duplicate analysis performed to monitor precision within a run Parallel analyses to monitor inter-technician method precision Confirmation of organisms done routinely

8. Personnel Administration Lab staff qualifications Continued education and monitoring of competency Good lab practices Standard operating procedures

9. Responsibilities of an Assessor To apply the standard Unbiased Not to judge the lab Provide a comprehensive report based on assessment against the standard

10. Assessment Team Selection of the assessment team Not a pass/fail approach Explain the process to the lab being assessed Create an informal atmosphere and an open approach

11. Assessment process Tour of the facilities Trace of tests Assessment of the quality system Assessment of the methods Stage meetings Reporting all the findings
