The Workgroup members are technical advisors to the monitoring and modeling workgroups of the Scientific, Technical Analysis and Reporting Team concerning field and analytical methodology and quality assurance issues related to collection, processing and assessment of water quality data. The Workgroup provides a forum for exchange of technical information focused on the standardization of methods/use of comparable methods throughout the Chesapeake Bay Monitoring Program. Members of the Workgroup participate in the Coordinated Split Sample, Blind Audit and Reference Sample Programs and use this information to evaluate the quality of the monitoring data and to identify areas that require further study.
To provide professional direction and guidance on field and laboratory methods and QA/QC, resulting in accurate and comparable Chesapeake Bay and tributary water quality monitoring data.

A training will be held at the DNREC Laboratory in Dover, DE to review nontidal sampling and analysis methods for the Nontidal Network (NTN) and QA/QC procedures. For details please view the program agenda. Contact Lea Rubin (firstname.lastname@example.org) or Mary Ellen Ley (email@example.com) with questions.
The purpose of this document is to provide field and laboratory methods and associated quality control (QC) requirements for use in Chesapeake Bay water quality monitoring programs, which will result in the generation of known and comparable data quality. State agency staff or subcontractors (Participants) will conduct field measurements and collect and analyze water and sediment samples for specific physical, chemical, and biological parameters according to the procedures in this document.
Conformance with these procedures provides a solid foundation for a wide variety of scientific and management investigations, e.g., attainment of water quality standards, characterization of the health of the Chesapeake Bay and its tributaries, evaluation of long-term trends, effectiveness of management actions, ecosystem processes and water quality model development and calibration.
