Harter, a UC ANR specialist based at UC Davis, and co-author Laurel Firestone, shared their thoughts in an op-ed penned for The Guardian. Firestone is co-executive director of the Community Water Center in California, which helps disadvantaged communities gain access to clean, affordable water.
The authors wrote that state records with information needed to characterize groundwater aquifers are kept confidential under a 64-year-old law that considers them proprietary to well drillers. The well logs contain data that is public in every other state in the West and include details such as where wells are located, their depth, potential pumping rates, diameter and descriptions of the sediments and rocks the wells go through.
"The lack of information is a major impediment to stewardship of the resource," the op-ed says.
California State Senator Fran Pavley introduced Senate Bill 20 in December, which if passed will make well log data publicly available in California.
"Perhaps as more community and farm wells dry up this summer, the legislature will extend its enthusiasm for transparency to the critical information needed for more equitable and sustainable management of our groundwater," Garter and Firestone conclude.

"Some farmers are going to be having to cut back at least in the short run," said Doug Parker, director of the UC California Institute for Water Resources.
Thomas Harter, UC Cooperative Extension specialist in the Department of Land, Air and Water Resources at UC Davis, predicted the farmers' successors will appreciate the coming regulations.
"In the long run, my view is that the next generation and two generations down of farmers will find this a lifesaver," Harter said.
The bills waiting for the governor's signature won't provide an instant fix, the story said. The law will take years to implement and it could take decades for the most depleted groundwater basins recover.
In most years, groundwater amounts to 30 to 45 percent of the state's water supply, but in dry periods, it increases to 60 percent. The new law will direct local public agencies to develop sustainable groundwater management plans. If they fail, the State Water Resources Control Board steps in. The legislation gives local basin managers the ability to:
- Collect fees from groundwater users
- Monitor withdrawals
- Limit pumping
- Buy water or water rights to replenish aquifers
The Association of California Water Agencies supports the new regulations; agricultural interests are opposed, the article says.
"We thought these bills were too far-reaching," said Paul Wenger, president of the California Farm Bureau Federation.
Thomas Harter, UC Cooperative Extension specialist in the Department of Land, Air and Water Resources at UC Davis. Harter made the comment on the National Public Radio program Here & Now, which is broadcast nationally.
According to the theory, individuals, acting independently and rationally according to each one's self-interest, behave contrary to the whole group's long-term best interests by depleting some common resource. The result for California groundwater in this drought year has been reliance on groundwater to meet fully two-thirds of the state's urban and agricultural water needs.
"It's a significant concern because it's not a rate at which we can continue to use this resource," Harter said. "It's not sustainable."
Here & Now host Jeremy Hobson pointed out that California is the last Western state to regulate groundwater. Last week the California legislature sent three bills to Gov. Brown that would end a commonly held view in California that property owners have the right to draw as much groundwater as they want from wells on their property.
The lack of regulation and a continuing drought have resulted in severe overdraft of the state's aquifer. By studying the state's geology and measuring groundwater levels over decades, scientists know how much water is there, Harter said. Californians should not expect any new hidden reservoirs to be found.
"The best way I think we can address this is make information about the resource more available and let people know what happens to the resource, where (water) comes in and where it goes out, and involve the public on the decision-making on how we want to manage that resource," Harter said.
Nervousness over California's epic drought has given way to alarm, reported Joby Warrick in the Washington Post. Streams and lakes are drying up, and now the aquifers are being pumped at an unsustainable rate.
The massive shift to groundwater has helped farmers survive this year, but a UC Davis study says tapping groundwater at the same rate into the future could soon deplete this valuable resource.
"A well-managed basin is used like a reserve bank account," said Richard Howitt, professor emeritus in the Department of Agricultural and Resource Economics at UC Davis. "We're acting like the super rich who have so much money they don't need to balance their checkbook."
Thomas Harter, UC Cooperative Extension groundwater specialist in the Department of Land, Air and Water at UC Davis, said depleting the aquifer is more serious than depleting water reservoirs because aquifers take far longer to replenish.
"It's a downward path," he said. "We cannot do what we did this year on a permanent basis."
Creedon spoke yesterday at a conference arranged by Fresno State's International Center for Water Technology. Also on the panel was Thomas Harter, UC Cooperative Extension specialist in the Department of Land, Air, and Water Resources at UC Davis, who described his recently released research report on nitrates in Tulare Lake Basin and Salinas Valley groundwater.
The conference featured panels and speakers on many of California's water issues, including underground water banking and Southern California's quest for new water sources, Grossi reported. However, no issue was bigger than Harter's study, he said.
Earlier Thursday, Harter and his research team presented details of the report to an audience of about 150 at the UC Kearney Agricultural Research and Extension Center. Two local television stations, ABC affiliate Channel 30 and CBS affiliate Channel 47, provided their viewers with live reports from the scene.
