Water Quality Database Inventory

GEO AquaWatch is pleased to offer you three Water Quality Inventories:

The General Water Quality Project Inventory is a list of known projects offering water quality data or data products.  Click here to download a copy of the most current general water quality project inventory from around the globe and here to find out what has changed since the last version. This list is not comprehensive, and will be updated from time to time.  

This Citizen Science Water Quality Project Inventory, compiled by Justine Spore (University of Wisconsin) in 2021, is a list of known CitSci projects targeting water quality information from around the globe.  This list is not comprehensive, and will be updated from time to time.

The Water Quality Database Inventory presented below was initially compiled by Brooklyn Poutra (NASA intern) in Fall 2022 and points users to useful water quality databases. This list is not comprehensive, and will be updated from time to time.
