Environmental QA Workshop
ASI #107, BASIC ENVIRONMENTAL QA/QC WORKSHOP - CHEMISTRY
OBJECTIVES OF COURSE
The quality assurance and quality control requirements presented during this
course are based on the State of Michigan and EPA method requirements. The
training presents practical examples for implementation of quality assurance,
quality control and basic chemistry skills.
The course is directed to quality assurance officers, laboratory managers, and
testing supervisors, analysts, and data reviewers. The course will provide
guidance on the general quality assurance/quality control (QA/QC) requirements
to acquire technically and legally defensible environmental data from laboratory
operations. A list of references in the course handout allows the opportunity to
further your understanding and obtain more specific information on the subjects
presented.
The course objectives are to:
· Define quality assurance and quality control practices,
· Provide examples of quality assurance principles,
· Present the specific quality control practices for spiking, methods of addition and matrix interferences,
· Demonstrate the use of statistical analysis,
· Present examples of logbooks for equipment maintenance, standards traceability and reagents preparation,
· Review chemistry principles related to titrations, colorimetric, instrumental, gravimetric and sample preparation techniques.
