Meeting Quality ObjectivesCommunicate:• General project information • Regulatory requirements• Reporting limits and analyses requirements• Analyses, constituents of concern, target analytes• Subcontracting requirements• How to communicate with each other• Validation objectives• Audit changes to the data• Other information (e.g., sampling requirements, blanks, turn, and
special reporting packages)
