Voluntary Groundwater Well Monitoring Program

It’s simple. Its FREE.
Participate and you will get current, accurate data about the groundwater levels at your property.

Now seeking property owners with wells in Petaluma Valley to participate in a local voluntary groundwater well monitoring program.

Participate in this program to;

Know how water depth changes over the course of the year and better understand how the groundwater system beneath your land responds to winter recharge and use over the dry months. In this long-term voluntary program, participants take measurements spring (April) and fall (October) over multiple years to reveal trends in response to recharge, pumping and climatic conditions.

Monitoring water levels benefits well owners

Monitoring well water levels provides essential data to help well owners manage water resources and:

  • Prevent water quality issues that result from aquifer levels dropping below minimum thresholds
  • Support the health of ecosystems that depend on groundwater to supply streams with water
  • Protect the aquifers that our local economy depends on, including agriculture and tourism

This program provides well owners:

(This program provides well owners:

  • Access to 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

What about water quality?

Petaluma Valley GSA’s will be launching a voluntary water quality monitoring program to better understand the potential for seawater intrusion in the southern portions of the basins. Staff will let you know if your well may be a candidate for this program.

Who is eligible to participate?

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

DIY Program

If your well is not in one of the high need zones, we encourage your participation in the DIY monitoring program which will include community workshops, written training materials and videos and a tool lending program.

Facilitated Program

If your well is in an area with patterns of decline, and an area designated high priority due to gaps in data, your well may be eligible to participate in the program where measurements are conducted for no charge to you by professionally trained technical staff.
