      About MDCB
The Board has developed, or is currently developing, a number of tools to assist in water-quality monitoring and data comparability efforts.
  • Methods: NEMI
    • NEMI is a free, searchable clearinghouse of methods and procedures for regulatory and non-regulatory analyses. Use NEMI first to compare and contrast the performance and relative cost of analytical, test, and sampling methods for environmental monitoring.
  • Data Elements
    • The broad metadata categories which characterize all types of data—who, what, when, where, why, and how—are being used to develop a modular WQDE approach that can be tailored to specific types of data.
      • Tools to Use
  • Data and Method Quality Objectives
  • Accreditation NELAC
    • The MDCB supports the NELAC accreditation plan in order to: (1) establish a uniform national accreditation process including the use of performance-based systems (PBMS), (2) develop uniform and consistent accreditation related policies and requirements, and (3) avoid duplication of effort. The accreditation Workgroup efforts are directed towards providing guidance to USGS, EPA, and other Federal, State and private sector agencies on NELAC accreditation issues..
