General
Information
Restoring the Chesapeake is closely tied
to the quantity and quality of information needed to answer questions like "How
is the Bay doing?" and "Are our efforts making a difference?" To
respond with confidence, the Chesapeake Bay Program maintains a Quality Assurance
Program for the monitoring and tracking of pollutants, water quality, land use,
algae, fish, crabs, submerged aquatic vegetation, etc. The Chesapeake Bay Quality
Assurance Program ensures that information from over 40 agencies and research
institutions are not only scientifically valid, but comparable among collaborators,
and of known and documented quality.
Quality Assurance Organization
The
Quality Assurance Program consists of an internal, EPA component within the Chesapeake
Bay Program Office and several collaborative quality circles within the Chesapeake
Bay Program Subcommittee structure. Within the Chesapeake Bay Program Office,
quality assurance work is done by the Quality Assurance (QA) Officer, the QA Coordinator,
and EPA Project Officers.
Subcommittee quality assurance is done through
the Analytical Methods and QA Workgroup, Living
Resources Modeling and Monitoring Workgroup and the Toxics
Characterization Workgroup. The
Chesapeake Bay Program Office Quality Management Plan
(2.4 MB) contains additional information on the Chesapeake Bay Program Office
quality system.
Quality
Assurance Planning Requirements for Grants and Cooperative Agreements
Organizations
conducting projects and research for EPA that generate, compile, or use environmental
data are required to establish and implement a quality system. Grantees and cooperators
describe their quality systems in two formal documents, the Quality Management
Plan and the Quality Assurance Project Plan.
Methods
and Quality Assurance
Scientists follow proven methods
and quality control procedures to collect environmental data. Methods are selected
collaboratively through the Analytical Methods and Quality Assurance Workgroup.
All field and laboratory procedures are documented in detail and can be accessed
through the following sites:
Quality Assessments and Performance
Evaluations
Data quality is systematically checked
at each stage of production using quality control samples. In addition, quality
assurance staff conduct on-site audits and monitor laboratory performance on inter-laboratory
split samples, reference samples and blind audit samples.
