Inventory of microbial monitoring data for surface water

The Department of Water and Sanitation, in cooperation with other agencies, monitors these sites because they have a high potential for contamination with microbial pathogens.
Site types include :

• Rivers
• Dam / Barrage
• Canal
• Estuary/Lagoon
• Wetland
• Spring/Eye
• Lake
• Pan

Site colours reflect the maximum aggregated annual class during the 5 years up to 2024-08-27 - grey markers flag 'old data'.
Click on a site to see a thumbnail summary of the microbial data, then click on the thumbnail for a complete time-series plot, which includes more detail about risk.
Disclaimer: classes are inferred from transient indicator species, and the current risk of exposure to pathogens may be higher or lower than shown here.

Special request: kindly inform us if you notice any errors in site positions or descriptions.
