Microbiology: E. coli & Faecal Coliforms
Switch tabs below to look at different variables.
E. coli
E. coli (cfu/100ml) results for the period 2015/16 to 2019/20 benchmarked against MfE swimming risk guidelines. Modelled grades (coloured lines on the map) are shown for River Environment Classification reaches order three and above. See methods for details on modelling and benchmarks.
Drag and scroll on the map to move and zoom in on areas of interest, hover on the site circles and river lines to see more information, click the top right checkboxes to show/hide layers (double clicking will bring that layer to the front), and use the selection box on the top left of the map ( ) to subset table data.
Click on table rows to highlight those sites on the map above and click on table headers or the arrows next to them ( ↓↑ ) to sort that column. n refers to the number of samples and units are cfu/100ml unless otherwise noted.
Faecal coliforms
Faecal coliforms (cfu/100ml) results for the period 2017/18 to 2019/20.
Drag and scroll on the map to move and zoom in on areas of interest, hover on the site circles and river lines to see more information, click the top right checkbox to show/hide rivers order three and above on the map, and use the selection box on the top left of the map ( ) to subset table data.
