Unlike California’s majestic rivers and massive dams and
conveyance systems, groundwater is out of sight and underground,
though no less plentiful. The state’s enormous cache of
underground water is a great natural resource and has contributed
to the state becoming the nation’s top agricultural producer and
leader in high-tech industries.
Groundwater is also increasingly relied upon by growing cities
and thirsty farms, and it plays an important role in the future
sustainability of California’s overall water supply. In an
average year, roughly 40 percent of California’s water supply
comes from groundwater.
A new era of groundwater management began in 2014 with the
Sustainable Groundwater Management Act, which requires local
and regional agencies to develop and implement sustainable
groundwater management plans with the state as the backstop.
For as long as agriculture has existed in the Central Valley,
farmers have pumped water from the ground to sustain their
livelihood and grow food consumed by much of the nation. This
has caused the ground in certain places to sink, sometimes
dramatically, eliminating valuable aquifer storage space that
can never be restored. The damage by subsidence extends to the
California Aqueduct, the 700-mile artificial river that conveys
water from Northern California to the valley and beyond as the
principal feature of the State Water Project.
The joint ground-mapping pilot project is designed to help
Soquel Creek Water District and the County of Santa Cruz locate
sandy soil areas to install collection basins and dry wells for

Fresh from gaining the long-sought federal approval for its
massive desert water project, Scott Slater, Cadiz president and
CEO, said it’s time for the project to “slow down” a bit.
… The Cadiz project involves pumping billions of gallons
of water annually from an underground aquifer in a remote part
of the Mojave Desert in San Bernardino County.
We ventured through California’s Central Valley, known as
the nation’s breadbasket thanks to an imported supply of surface
water and local groundwater. Covering about 20,000 square
miles through the heart of the state, the valley provides 25
percent of the nation’s food, including 40 percent of all fruits,
nuts and vegetables consumed throughout the country.
During California’s five-year drought, the row of ponds in the
desert north of the Palm Springs often lay empty and dry. But
this year, the ponds have been filled to the brim with a record
amount of water from the Colorado River. The Coachella
Valley’s water utilities are using the influx of imported water
to chip away at the long-term problem of groundwater overdraft.
The state of California is asserting landownership rights along
a proposed pipeline’s path that would help carry groundwater
from a remote part of the Mojave Desert in San Bernardino
County to Orange County and other communities.
A state commission is throwing a new hurdle in front of Cadiz
Inc.’s plans to turn a remote desert valley into a lucrative
water source for Southern California. In a Sept. 20 letter to
Cadiz, the State Lands Commission informed the company that its
proposed water pipeline crosses a strip of state-owned land and
therefore requires a state lease.
If you want a new well in California, you might have to let
your neighbors know how much water you plan to pump. That’s if
it’s tapping a critically overused aquifer, and if a bill on
Gov. Jerry Brown’s desk survives calls for a veto.
Now, a private company wants to use the pits for a $2-billion
hydropower project. The plant, proponents say, would help boost
renewable energy use in Southern California and lower
greenhouse gas emissions. But park officials fear the
hydropower project could draw down local groundwater levels and
California survived its historic drought, in large part by
using groundwater. It was a lifeline in the Central Valley,
where it was the only source of water for many farmers.
California regulators are charged with protecting that
groundwater, but for years they failed to do so.
Stanislaus County will try a new groundwater treatment system
to keep the former Geer Road landfill from polluting the
Tuolumne River and nearby wells. The county will pay a Southern
California contractor $1.74 million to build the groundwater
extraction and treatment equipment at the old landfill on the
north side of the Tuolumne River, about a mile northeast of
Groundwater replenishment happens through direct recharge and
in-lieu recharge. Water used for direct recharge most often comes
from flood flows, water conservation, recycled water,
desalination and water transfers, according to DWR.
The battle over plans by a Los Angeles company to sell water
pumped from aquifers underneath Mojave Desert conservation
areas heated up again this week when state legislation was
amended to require a new round of state reviews.
The SGMA [Sustainable Groundwater Management Act] is now
kicking into gear as its first major deadline arrives: By June
30, counties and regional water managers must form “groundwater
sustainability agencies,” or GSAs – the task forces that will
eventually be responsible for developing their own sustainable
groundwater use plans. Districts that fail or choose not to
create a GSA will be subject to intervention by the State Water
Resources Control Board.

Land subsidence caused by groundwater pumping has been a problem
for decades in the San Joaquin Valley, but an increased reliance
on aquifers during the last decade has resulted in subsidence
rates in excess of a foot per year in some parts of the region.

Sinkholes are caused by erosion of
rocks beneath soil’s surface. Groundwater dissolves soft
rocks such as gypsum, salt and limestone, leaving gaps in the
originally solid structure. This is exacerbated when water is
acidic from contact with carbon dioxide or acid rain. Even
humidity can play a major role in destabilizing water
Irrigation is the artificial supply of water to grow crops or
plants. It optimizes agricultural production, obtained from
either surface or groundwater, when the natural quantity and
distribution of rain is insufficient. Different irrigation
systems are not necessarily mutually exclusive, but in
practical use are often combined or serve as subcategories of one
States Geographical Survey (USGS) defines freshwater as
containing less than 1,000 milligrams per liter dissolved solids.
However, 500 milligrams per liter is usually the cutoff for
municipal and commercial use. Most of the Earth’s water is
saline, 97.5 percent with only 2.5 percent fresh. Of this water,
about 70 percent is confined in glaciers and permanent snow in
the Arctic, meaning the remaining available water is accessible
after treatment, as potable water.
Springs are where groundwater becomes surface water, acting as openings
where subsurface water can discharge onto the ground or directly
into other water bodies. They can also be considered the
consequence of an overflowing
aquifer. As a result, springs often serve as headwaters to streams.
A federal judge on Tuesday blocked the U.S. Bureau of Land

Alluvium generally refers to the clay, silt, sand and gravel that
are deposited by a stream, creek or other water body.
Alluvium is found around deltas and rivers, frequently
making soils very fertile. Alternatively, “colluvium” refers to
the accumulation at the base of hills, brought there from runoff
(as opposed to a water body). The Oxnard Plain in Ventura
County is a visible alluvial plain, where floodplains have
drifted over time due to gradual deposits of alluvium, a feature
also present in Red Rock Canyon State Park in Kern County.

The Central Valley has been hit hard by the long-running
drought. La Niña has failed to deliver the relief everyone was
hoping for, but researchers at Stanford have discovered what
could be good news for the region and for the state.
The Central Valley is home to California’s productive farming
belt, but the region’s groundwater is so severely overdrafted
in some places that the land has been sinking. … Now
scientists from Stanford University have found that the region
might actually have three times more groundwater than previous
estimates, which are decades old.

including one from [Gary] Serrato’s [Fresno Irrigation]
Water year 2016 began with the potential for heavy El Niño rains
that captured the attention of the public. State and federal
officials knew that California’s drought-stricken reservoirs
would not recover that quickly.
Hydrologic conditions, precipitation patterns, the need for
fishery flows, and forecasts of state and federal water project
operations were all discussed at a special FREE briefing
held February 23, 2016. Sponsored by the California
Department of Water Resources and the Water Education Foundation,
the briefing was held at the Sacramento Convention Center, Room

Almost 28 years since state regulators learned there was a
chromium-6 problem in Hinkley, officials from the same agency
approved a comprehensive clean-up order for the world’s largest
known plume of this cancer-causing chemical.
On Tuesday, the Board of Supervisors unanimously approved an
amended water recycling agreement between the county Water
Resources Agency and the Monterey Regional Water Pollution
Control Agency, the primary backer of the groundwater
replenishment project also known as Pure Water Monterey.
In the drought-ravaged Central Valley, scientists are using a
new imaging technology to find ancient worlds of trapped water,
hidden hundreds of feet underground. … This week, a
helicopter swept 60 linear miles of parched fields in the
Tulare Irrigation District in one of the most arid regions of
The governor should use his emergency powers under the existing
drought to ban new wells in areas where groundwater pumping is
causing significant economic damage. I [Gerald H. Meral] don’t
take this position lightly. I understand it would harm people
who need groundwater to keep their farms going.
In an attempt to prevent its oil industry from contaminating
groundwater sources that could be used for drinking water,
California regulators closed 33 wells last week that were
injecting oilfield waste into protected aquifers.
It’s been one year since California Governor Jerry Brown signed
a landmark law to manage the state’s groundwater. The
California Water Commission has approved new groundwater basin
boundaries – the first major step in implementing the law.
On October 9, 2015, Governor Brown completed what is probably
one of the most remarkable two years in water legislation in
California’s history. … In signing SGMA, the Governor
pledged that during the 2014/15 legislative session, he would
submit a proposal to streamline groundwater
adjudications. With the signing of AB 1390 (Alejo) and SB
226 (Pavley), the Governor kept his promise.
A much-anticipated “Godzilla” El Niño this winter may refill
California’s drought-diminished reservoirs, but it won’t do
much to restock the severely depleted aquifers we rely upon to
get by during droughts. One reason for this is the sheer depth
of California’s precipitation deficit – the deepest of any
drought in 120 years of recordkeeping. The state has been drier
than normal for 10 of the past 14 years.
The CEO for embattled Cadiz Inc. has a plan to keep alive a
controversial project to transfer ancient groundwater in a
remote part of San Bernardino County’s Mojave Desert to parts
of Orange County and other locations, where it could serve as
many as 400,000 people.
California American Water is expected to resume pumping from
its stalled Monterey Peninsula desalination project test slant
well operation by early November after the Coastal Commission
gave its unanimous approval Tuesday.
The Eastside Water District board voted Thursday to ask its
farmers for $6 million for a groundwater recharge project. The
system would eliminate no more than 10 percent of the overdraft
in the 61,000-acre district, which straddles Stanislaus and
Merced counties southwest of Turlock Lake, but backers said it
would be a worthwhile start.
Saltwater intrusion challenges nearly every town and farm
district in California that borders the Pacific. Many have been
fighting back the ocean for generations. Bulletin 52, the first
state report to document the salt problem in the Salinas
Valley, a farming center just south of Watsonville, was
published in 1946.
The Hinkley plume of cancer-causing chromium-6 may appear to be
shrinking in future maps. But ongoing cleanup may not be the
only reason. It might be that the methodology for drawing the
plume has changed.
On September 16, 2014, Governor Jerry Brown, cheerfully
triumphant, signed into law the Sustainable Groundwater
Management Act, which many observers assert is the most
significant addition to California’s water protection code in a
For years, an obscure team of water wonks has met each month in
a conference room at the California Water Service Co. offices
in downtown Stockton. Their charge: To protect the region’s
precious groundwater, an invisible natural resource as
little-known as those who guard it.
Eleven local governmental bodies, trade groups, labor groups
and others have filed amici “friend of the court” support for
the Cadiz Valley Water Conservation, Recovery and Storage
Project in a remote Mojave Desert section of San Bernardino
[Derek] Chernow’s declaration, obtained by the Associated
Press, was contained in an Aug. 21 court filing in a lawsuit
brought by a group of Central Valley farmers who allege that
oil production approved by Brown’s administration has
contaminated their water wells.
How many domestic wells are having trouble throughout the
state? More than 2,500. That’s not an exact figure, but its
better than the smattering of reports that had been collected
before the most recent statewide summary.
Portions of the San Joaquin Valley floor are sinking at an
alarming rate as farmers pump ever more groundwater during
California’s extended drought, according to a NASA study
released Wednesday. The report, generated by NASA’s Jet
Propulsion Laboratory for the state Department of Water
Resources, sheds new light on the phenomenon known as
Vast areas of California’s Central Valley are sinking faster
than in the past … Meanwhile, the Department of Water
Resources is launching a $10 million program to help counties
with stressed groundwater basins to develop or strengthen local
ordinances and conservation plans.
Until things are back to normal, some folks in Glenn County
want to see a halt to new well drilling. Tuesday, the issue
will be before the Glenn County Board of Supervisors, at the
request of farmer Sharron Ellis.
Los Angeles-based land and water resources company Cadiz Inc.
on Monday announced it has lined up a technology company to
help it remove the cancer-causing chemical Chromium-6 from its
groundwater in the San Bernardino County desert.
SMUD’s big bet on a system to store energy by pumping water
uphill just got a little more complicated. The state wants the
Sacramento Municipal Utility District to monitor groundwater at
the site, a remote spot near Camino, for an entire year before
The depletion of groundwater stores also is a problem familiar
to farmers struggling with drought in California, where pumping
for irrigation has put the state’s Central Valley Aquifer under
the most strain of any aquifer in the U.S., according to NASA
