The purpose of this document is to provide field and laboratory methods and associated quality control 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 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.
