Private Well Owners (PWOs) are individuals or businesses with a groundwater well that they operate independently of any water agency, and that supplies water for drinking, domestic use, livestock, and/or irrigation. Any well serving up to four connections is considered a private well.
Private Well Owners in the Basin are encouraged to:
1) Sign up to the MGA email listserve. We use the email list to distribute quarterly e-news updates on MGA news and events;
2) Attend MGA meetings to learn more about Basin groundwater management and share your ideas.
Typical Domestic Well Users
The Sustainable Groundwater Management Act (SGMA) defines a “de minimis” user as “a person who extracts, for domestic purposes, two acre-feet or less of groundwater per year.” Most private users with a domestic well use less than two acre-feet of water per year. The average household uses approximately one-third of an acre-foot per year. If your household relies on a single domestic well and you are not watering crops or large areas of landscape, it is likely that you are a de minimis user.
Board Representation
To ensure that the concerns and interests of PWOs are represented within the Mid-County Groundwater Agency (MGA), the Board of Directors includes three Directors and one Alternate Director who represent the interests of the private well owners in the Santa Cruz Mid-County Groundwater Basin. PWOs were engaged in the development of the Basin GSP and continue to be involved in the GSP implementation. PWO Directors serve four-year terms; the Agency publicly solicits applications for Well Owner Representatives to serve on the Board. The next call for applications is anticipated to occur in summer/fall 2025.
Metering for Larger (non de minimis) Users
Under SGMA, the MGA has the authority to require registration, installation of meters, and reporting by larger, non-de minimis wells (users extracting more than 2 acre-feet per year). In June 2024, the MGA Board of Directors adopted a policy requiring well registration, metering, and reporting for certain non- de minimis groundwater users. All private wells used for commercial or agricultural purposes that pump more than 5 acre-feet per year are required to install meters and report groundwater extraction. Similarly, wells in priority areas, defined as along the coast and within 1,000 feet of interconnected surface waters that pump more than 2 acre-feet per year are also required to install meters and report groundwater extraction.
The well registration, metering, and reporting requirements policy requires well registration by December 31, 2024 and meter installation by September 30, 2025. For more information visit Metering Program.
Free Residential Well Water Quality Testing
The County of Santa Cruz offers a free water quality testing program in Santa Cruz County for residents who rely on a household water well. Testing services are available in both English and Spanish. To schedule a free testing, call (844) 613-5152 or visit www.centralcoastwelltesting.org.
The free residential well testing initiative aims to provide vital information on potential health risks associated with harmful substances in drinking water. Participating residents will receive comprehensive testing results and guidance to protect their wells from contamination. High levels of contaminants in drinking water can have serious health effects, particularly for vulnerable populations such as pregnant women and young children. All residents are encouraged to take advantage of this complimentary, non-regulatory testing service.
