About MDCB


The Performance Based Systems (PBS) Workgroup was established to promote the design and implementation of a system for selecting methods of analysis according to their performance and the specified data-quality needs.
The National Environmental Methods Index (NEMI) has been developed online as a free, searchable clearinghouse of methods and procedures, designed to assist method comparisons for regulatory and non-regulatory analyses.
The Water Quality Data Elements Workgroup has been charged to develop and recommend a “core” set of data elements for voluntarily reporting water quality monitoring results, to facilitate sharing of comparable data, while recognizing the objectives of individual programs.
The Laboratory and Field Accreditation workgroup was formed to identify gaps in monitoring programs that may limit acceptance of their data, and to make recommendations to workgroups in the National Environmental Laboratory Accreditation Conference (NELAC) and the Environmental Laboratory Advisory Board (ELAB).
The Biology and Microbiology Workgroup was created to recognize the diversity of biological and microbiological methods being widely applied, and to promote the use of procedures in the field and laboratory that are adequately documented and validated.
The Nutrients Workgroup will develop input on methods and data for nutrients, to contribute to activities of PBS, NEMI, and WQDE workgroups, and to respond to national monitoring programs concerned with nutrients.
The New Technologies Workgroup was established to give recognition to methods of analysis that show promise in increasing the quantity and quality of data, and for expanding the range of problems that can be addressed in current monitoring programs.
The Outreach and Publicity Workgroup was formed to interact with all sectors of the monitoring community, to ensure that their needs are represented in achieving comparable methods and data.
