The NADP/NTN Network operates a comprehensive quality assurance
program. Within this program, the network follows an extensive set of
QA/QC procedures covering field, laboratory, and data management
operations. These procedures involve but are not limited to the
following: the use of standard reference materials by both field and
laboratory personnel; measurement of various types of blanks;
duplicate analyses including a collocated sampling program; audits of
site configurations, equipment, and performance; interlaboratory
comparison programs; data verification and integrity checks. Annual
reports of network quality are available from the Coordination Office.
