GSA seeks volunteers for well monitoring program

Both the Petaluma Valley and Sonoma Valley Groundwater Sustainability Agencies (GSA) are seeking property owners with wells in Petaluma Valley and Sonoma Valley to participate in a local voluntary groundwater well monitoring program.


Who can participate?
Residential and agricultural well owners in Sonoma County are welcome to sign up and then staff will help you find out which program is the best fit for your location in the basin, either the facilitated program or the DIY program.


The program provides the following to landowners:

  • Tools and training to collect groundwater level measurements from their well
  • Access to a data dashboard with seasonal and long-term groundwater level trends for your well
  • In some cases, receive water quality data for your well
  • Additional optional program to meter well water pumping to better understand demand of beneficial water use (coming soon)
  • Water-level data submitted through the program will become public information, but well owner information will remain private
