Data Reliability Statement The environmental data stored on this system is both current and historical. Historical data has been collected under a wide variety of geopositioning, sampling, analytical, and quality assurance regimes. For some of the historical data, particularly data collected before 1975, no formal quality assurance program can be associated with the data. For some pre-1980 data the analytical method used to generate data is undocumented. Some recent monitoring studies may have a Project Status of "QA Incomplete", which indicates that the data review has not been completed. Data associated with the QA Incomplete status is provisional, and subject to change. Data users should be aware of these qualifications, and use data from this site with caution.
