Developing A National Water Quality Monitoring Network Design
Developing A National Water Quality Monitoring Network Design NWQMC July 26, 2005 Origins of the Proposal An Ocean Blueprint for the 21st Century Final Report of the U.S. Commission on Ocean Policy The US Ocean Action Plan
The Administrations Response Both called for the creation of a National Water Quality Monitoring Network National Water Quality Monitoring Network Three Recommendations: 1. Develop network that coordinates and expands existing efforts 2. The network should include coverage in
both the coastal and upland areas that affect them, and be linked to the Integrated Ocean Observing System 3. Network must have clear goals, specify core variables, and an appropriate sampling framework, and be periodically Council is a 35-member committee under the Advisory Committee on Water Information (ACWI) ACWI is Chartered under the Federal Advisory Committee Act ACWI members accepted task from CEQ and
NSTC for Council to Design a National Water Quality Monitoring Network (NMN) Council has already developed many products to address these problems (see Council brochure) National Water Quality Monitoring Network Challenge:
Common information goals Compatible design approaches Sampling timing Metadata standards Parameter specifications Field data collection & handling Analytic procedures Data storage, and data access practices

Retain Add or Extend Enhance Define as external to the Network Goals of the National Water Quality Monitoring Network Integrate, coordinate, and as necessary enhance water quality monitoring efforts
needed to make informed management decisions for sustainable use of aquatic resources. Communicate the availability of quality assured data, and disseminate information products relevant to national, regional and local needs. Objectives of the National Water Quality Monitoring Network 1. Define status and trends of key water quality parameters and conditions on a nationwide basis. 2. Provide data relevant to determining whether goals, standards,
and resource management objectives are being met, thus contributing to sustainable and beneficial use of coastal and inland water resources. 3. Provide data to identify and rank existing and emerging problems to help target more intensive monitoring, preventive actions, or remediation. 4. Provide data to support and define coastal oceanographic and hydrologic research, including influences of freshwater inflows. 5. Provide quality-assured data for use in the preparation of interpretive reports and educational materials. The Six Environments Major river systems and major
