Surface Water - Indicator Bacteria Results

Indicator bacteria data from the California Environmental Data Exchange Network (CEDEN) and BeachWatch databases. Results include E. coli, enterococci, fecal coliforms, and total coliforms. There is some overlap with the CEDEN Water Chemistry dataset (https://data.ca.gov/dataset/surface-water-chemistry-results). Both datasets draw from the same source, but the resources here are updated more frequently to support the Safe to Swim map on the Water Boards My Water Quality portal (https://mywaterquality.ca.gov/safe_to_swim/index.html).
