FreshWater Watchers around the world are uploading valuable data on water quality, including nitrate and phosphate levels, turbidity, and visual factors. Use our interactive map to view and analyse their measurements.

Click on the map to zoom in and select individual records. You can also use the select tool (found in the top-right corner of the map) to draw a box around the data points you wish to examine. This will allow you to compare median nitrate and phosphate concentrations, and average turbidity measurements by month and year. Make multiple selections to compare measurements by region. Your selection data will be available to download. Please view our metadata file for licensing details and data descriptions.
