This interactive map displays bacterial sampling results (E. coli, enterococcus, fecal coliforms, and total coliforms) for coastal and inland monitoring locations over time.
The data shown on this map are sourced from the California Environmental Data Exchange Network (CEDEN), BeachWatch database, and Central Valley E. coli Monitoring Results interactive map. The data are accessed using the public API on the California Open Data Portal. The CEDEN/BeachWatch dataset is updated daily on weekdays. The Central Valley Water Board E. coli Monitoring dataset is updated weekly.
The data can change at any time and should not be used for any particular purpose other than general reference.
