Quality Assurance of Environmental Measurements

PACS Course Number 60

9 AM to 5 PM

The course instructors are Dr. Henry Nowicki and Bill Purves. They have provided this 4-day survey course for many years to more than a thousand participants. This course provides general principles, organic measurement quality assurance (QA), and the QA for metal measurements. Increasing laboratory data quality and meeting user needs are present and futuristic goals. QA of environmental measurements is a key factor for technical and business success. Providers and users of laboratory data need to be concerned about quality assurance. Proper application of QA principles can help solve or prevent problems. This course is designed for: managers, engineers, chemists, QA specialists, and legal specialists who have responsibilities for data quality. If laboratory data quality is important to you, this course is for you. The course agenda is below.

The course content includes: glossary/acronyms, benefits/costs of QA/QC, basics of QA/QC, staff training, auditing, sampling, archives, holding times, preservatives, instrument performance, calibration, blanks, matrix spike, compound identification, interferences, system performance, reporting data, basic statistics, control charting, EPA methods, how to establish a QA Program, Good Laboratory Practices (GLP), and Good Automated Laboratory Practices (GALP). QA guidelines recommended by the EPA will be the course focus. The first two days will emphasize general QA principles and organics. The third day will focus on QA of metals. An additional recommended course on these subjects is "Environmental Data Validation"
