The water quality from private (non-commercial) wells is not regulated or monitored by any outside agency or company. It is the responsibility of the private well owner to ensure that their well water is safe.

(SB) 252 - Additional Information Required for New Wells within "Critically Overdrafted Basins" - Supplemental Well Application Forms (click here to view completed forms)

On October 6, 2017 Governor Brown signed Senate Bill (SB) 252 which became effective on January 1, 2018.  Subject to certain exceptions, (SB) 252 requires that the County request from every applicant for a permit for a new water well located within a “critically overdrafted basin” certain information about the proposed well such as location, depth, and pumping capacity.  The County must also make this information easily accessible and available to both the public and groundwater sustainability agencies. Click here to view the full text of (SB) 252.
