When Gov. Jerry Brown in September signed a package of three bills designed to curb overpumping of water from underground aquifers, the historic legislation sent fear and panic throughout Sonoma County. Residents who depend on underground wells as their primary source of water contacted county officials to ask how the laws would affect them, and farmers whose operations require a steady supply of water lobbied hard to be included in conversations about restrictions going forward.
County water officials and supervisors heard concerns about mandatory groundwater monitoring and rationing, and fielded questions about fines and penalties associated with pumping.
Sonoma County this week unveiled its first formal response to a wave of queries over the past six months about how California’s Sustainable Groundwater Management Act, which establishes the first rules for pumping groundwater in the Golden State, would affect property owners and agriculture.
“Monitoring and conserving groundwater is no longer going to be voluntary,” said Jay Jasperse, chief engineer and director of groundwater management for the Sonoma County Water Agency. “Some people were saying they’re mad, that it infringes on private property rights and water rights, but on the other hand, we’ve also heard from people who are saying it’s about time to regulate groundwater.”
Between now and June 2017, Sonoma County must form a local agency to develop and oversee plans for achieving sustainable groundwater levels in each of the county’s 14 underground basins.
Three of the aquifers — the Santa Rosa Plain, the Sonoma Valley and the Petaluma Valley basins — have been singled out by state water officials as among 127 statewide that are in danger of being depleted. That creates the possibility of saltwater intrusion into freshwater; sinking land; and permanent losses of water storage capacity underground in the county’s three largest basins, which double as major population centers.
California’s drought, now in its fourth year, is exacerbating groundwater depletion. Residential users and farmers increasingly are being forced to rely on underground reserves as surface supplies dwindle. County water officials say that during drought years, 60 percent of the state’s water supply comes from underground reserves.
“There are a lot of pressures on these aquifers,” Jasperse said. “We’re worried about them becoming severely depleted; they’re very vulnerable.”
Sonoma County has seven years to figure out how to prevent permanent damage to its underground basins, and if they aren’t healthy by 2042, the state can step in and take over, imposing steep fines, shutting down wells and relegating local control.
Meanwhile, the county is in the beginning stages of developing a local plan to monitor and manage groundwater supplies, focusing on recharge and conservation.
Supervisors on Tuesday launched a two-year plan to gather input from cities, agricultural users, environmental groups and property owners. Local government agencies, in charge of land use and water supplies, said they’ll use that input to come up with future groundwater policies. Those could include registering and monitoring wells, setting minimum distances between new wells, requiring users to report how much water is being pumped and imposing fees on property owners to fund groundwater recharge and conservation projects.
The regulations come as California develops sweeping new rules in an attempt to adapt to future water shortages. Brown, with state legislators, on Thursday introduced a $1 billion drought relief package aimed at fast-tracking water infrastructure projects that could encourage development of desalination and recycled water systems. Days before, the State Water Board imposed restrictions on residential water use.
