Nitrate—the oxidized form of dissolved nitrogen— is the main
source of nitrogen for plants. It occurs naturally in soil and
dissipates when the soil is extensively farmed. Thus, nitrogen
fertilizers are applied to replenish the soil. However, these
nitrates can be toxic, especially when they enter the food chain
via groundwater and surface water.
California state prosecutors are taking Sable Offshore to
court, accusing the oil company of repeatedly discharging dirt
and other material into coastal streams and wetlands without a
permit as it rushed to bring a pipeline and an offshore
drilling platform back online. … The lawsuit accuses
Sable of digging around the idle pipeline it is seeking to
repair and reopen without first seeking a permit from the
Central Coast Regional Water Quality Control Board. … The
work, called “pig and dig” operations, risks damaging the
“sensitive aquatic and riparian habitat” by discharging dirt
and vegetation in violation of state water quality rules,
according to the complaint.
Ten environmental and animal rights organizations sued EPA on
Monday for abandoning a Biden-era plan to require stronger
pollution controls at slaughterhouses, a decision that they say
violates the Clean Water Act. Slaughterhouses and meat
rendering facilities are a major source of nitrogen and
phosphorus pollution, which can degrade water quality and fuel
harmful algal blooms. In 2021, EPA agreed to update wastewater
standards for the industry in response to a similar
lawsuit. The agency proposed new standards in early 2024,
but the Trump administration reversed course last month.
The 2025 surface and groundwater monitoring under the RPP and
WDR programs was completed by August. For the Rice Pesticide
Program (RPP), no detections of thiobencarb were reported above
the agricultural drain performance goal. … The Rice
Waste Discharge Requirements (WDR) surface water program
monitored benzobicyclon and bispyribac-sodium, with generally
good results. … The Rice Waste Discharge Requirements
(WDR) groundwater program reported low levels (consistent with
historical averages) of nitrates in shallow groundwater beneath
rice fields.
… The leafy greens and other produce grown in the Salinas
Valley need lots of fertilizer, but that demand plus the fact
that most of these crops have shallow roots, means it’s easy
for extra nitrogen to get into the groundwater here. It
dissolves in water and sinks below the roots, eventually
reaching the aquifer. And once it’s there, nitrate—which is the
form of nitrogen most fertilizers take—is hard to remove.
… That’s part of the challenge for the Central Coast,
where over 14,000 people rely on water with dangerous levels of
nitrates that can elevate risks of cancers, thyroid problems
and blue baby syndrome.
A pilot program in the Salinas Valley run remotely out of Los Angeles is offering a test case for how California could provide clean drinking water for isolated rural communities plagued by contaminated groundwater that lack the financial means or expertise to connect to a larger water system.
Martha Guzman recalls those awful
days working on water and other issues as a deputy legislative
secretary for then-Gov. Jerry Brown. California was mired in a
recession and the state’s finances were deep in the red. Parks
were cut, schools were cut, programs were cut to try to balance a
troubled state budget in what she remembers as “that terrible
time.”
She now finds herself in a strikingly different position: As
administrator of the U.S. Environmental Protection Agency’s
Region 9, she has a mandate to address water challenges across
California, Nevada, Arizona and Hawaii and $1 billion to help pay
for it. It is the kind of funding, she said, that is usually
spread out over a decade. Guzman called it the “absolutely
greatest opportunity.”
One of California Gov. Gavin
Newsom’s first actions after taking office was to appoint Wade
Crowfoot as Natural Resources Agency secretary. Then, within
weeks, the governor laid out an ambitious water agenda that
Crowfoot, 45, is now charged with executing.
That agenda includes the governor’s desire for a “fresh approach”
on water, scaling back the conveyance plan in the Sacramento-San
Joaquin Delta and calling for more water recycling, expanded
floodplains in the Central Valley and more groundwater recharge.
Low-income Californians can get help with their phone bills, their natural gas bills and their electric bills. But there’s only limited help available when it comes to water bills.
That could change if the recommendations of a new report are implemented into law. Drafted by the State Water Resources Control Board, the report outlines the possible components of a program to assist low-income households facing rising water bills.
The growing leadership of women in water. The Colorado River’s persistent drought and efforts to sign off on a plan to avert worse shortfalls of water from the river. And in California’s Central Valley, promising solutions to vexing water resource challenges.
These were among the topics that Western Water news explored in 2018.
We’re already planning a full slate of stories for 2019. You can sign up here to be alerted when new stories are published. In the meantime, take a look at what we dove into in 2018:
Disadvantaged communities are those carrying the greatest
economic, health and environmental burdens. They include
poverty, high unemployment, higher risk of asthma and heart
disease, and often limited access to clean, affordable drinking
water.
More than a decade in the making, an
ambitious plan to deal with the vexing problem of salt and
nitrates in the soils that seep into key groundwater basins of
the Central Valley is moving toward implementation. But its
authors are not who you might expect.
An unusual collaboration of agricultural interests, cities, water
agencies and environmental justice advocates collaborated for
years to find common ground to address a set of problems that
have rendered family wells undrinkable and some soil virtually
unusable for farming.
Joaquin Esquivel learned that life is
what happens when you make plans. Esquivel, who holds the public
member slot at the State Water Resources Control Board in
Sacramento, had just closed purchase on a house in Washington
D.C. with his partner when he was tapped by Gov. Jerry Brown a
year ago to fill the Board vacancy.
Esquivel, 35, had spent a decade in Washington, first in several
capacities with then Sen. Barbara Boxer, D-Calif., and then as
assistant secretary for federal water policy at the California
Natural Resources Agency. As a member of the State Water Board,
he shares with four other members the difficult task of
ensuring balance to all the uses of California’s water.
Many Californians don’t realize that when they turn on the
faucet, the water that flows out could come from a source close
to home or one hundreds of miles away. Most people take their
water for granted; not thinking about the elaborate systems and
testing that go into delivering clean, plentiful water to
households throughout the state. Where drinking water comes from,
how it’s treated, and what people can do to protect its quality
are highlighted in this 2007 PBS documentary narrated by actress
Wendie Malick.
A 30-minute version of the 2007 PBS documentary Drinking Water:
Quenching the Public Thirst. This DVD is ideal for showing at
community forums and speaking engagements to help the public
understand the complex issues surrounding the elaborate systems
and testing that go into delivering clean, plentiful water to
households throughout the state.
The 28-page Layperson’s Guide to Groundwater is an in-depth,
easy-to-understand publication that provides background and
perspective on groundwater. The guide explains what groundwater
is – not an underground network of rivers and lakes! – and the
history of its use in California.
Nitrate—the oxidized form of dissolved nitrogen— is the main
source of nitrogen for plants. It occurs naturally in soil and
dissipates when the soil is extensively farmed. Thus, nirtrogen
fertilizers are applied to replenish the soil. However, these
nitrates can be toxic, especially when they enter the food chain
via groundwater and surface water.
In California, the State Water Resources Control Board lists
nitrate as one of California’s most challenging and growing water
problems.
California boasts some of the finest quality drinking water on
the planet. Every day, people turn on their tap and receive
clean, safe water with nary a thought. But the water people take
for granted isn’t so reliable for residents of small water
systems and many disadvantaged communities (DACs) in rural
agricultural areas.
This printed issue of Western Water examines
groundwater management and the extent to which stakeholders
believe more efforts are needed to preserve and restore the
resource.
