In an effort to protect more than 5 million Californians from a
cancer-causing contaminant, state regulators today set a new
standard that is expected to increase the cost of water for
many people throughout the state. The State Water Resources
Control Board unanimously approved the nation’s first drinking
water standard for hexavalent chromium, which is found
naturally in some California groundwater as well as water
contaminated by industries. Now water suppliers will be forced
to install costly treatment to limit the chemical in water to
no more than 10 parts per billion — equivalent to about 10
drops in an Olympic-sized swimming pool.
Lake Powell could reach a four-year high this spring and summer
as snowmelt supplements the reservoir’s water levels. Lake Mead
in Nevada and Arizona and Lake Powell in Utah and Arizona have
suffered from a regional drought for years, and excessive water
usage is slowly depleting the Colorado River faster than
natural weather patterns can fill it. An above-average snowfall
and excessive precipitation last spring and this winter have
bolstered the water levels at Lake Powell and Lake Mead, and
new data from the U.S. Bureau of Reclamation revealed that the
nation’s second-largest reservoir could rise by up to 50 feet
by mid-summer.
The conversation surrounding California’s water continues. The
Sites Reservoir project northwest of Sacramento has a price tag
of $4 billion and is funded by local, state and federal
dollars. The 1.5 million-acre project would divert water from
the Sacramento River into a valley near Maxwell, California,
and use it for storage. California water rights are a bit
tricky – and strict – and that’s the phase the Sites Project
Authority is in. They say things are ramping up, however. A
hearing officer has put forth a schedule for the hearings
surrounding water rights to conclude by the end of this year
and a decision could be made in early 2025. … There’s been
pushback [on the project] from environmental groups.
In much of the United States, groundwater extraction is
unregulated and unlimited. There are few rules governing who
can pump water from underground aquifers or how much they can
take. This lack of regulation has allowed farmers nationwide to
empty aquifers of trillions of gallons of water for irrigation
and livestock. Droughts fueled by climate change have
exacerbated this trend by depleting rivers and reservoirs,
increasing reliance on this dwindling groundwater. In many
places, such as California’s Central Valley, the results
have been devastating. As aquifers decline, residential wells
start to yield contaminated water or else dry up
altogether, forcing families to rely on emergency deliveries of
bottled water.
Frustrated with the amount of water dribbling down the western
reach of the Kern River, plaintiffs in an ongoing lawsuit over
the river filed a motion Tuesday asking the judge in the case
to intervene. The motion says the City of Bakersfield has
not maintained flows required to keep fish in good condition,
particularly in the areas of the river from Allen Road
westward. “Fish have died and habitat has dried up and
the Bakersfield community has lost much of the living river
that it had enjoyed for almost all of 2023,” it says. The
motion seeks to compel the city to keep the flow at a specified
level based on water levels where the river enters the city’s
jurisdiction. The city’s water attorney Colin Pearce said
the motion is being reviewed and the city will respond
accordingly.
Proposed state legislation to modify California’s longstanding
farmland conservation law could pave the way for large swaths
of farm acreage to be repurposed as sites for renewable energy
projects. The California Land Conservation Act of 1965,
commonly known as the Williamson Act, preserves farmland by
assessing property taxes based on the land’s agricultural value
rather than its full market value. Landowners with Williamson
Act contracts, which cover about half the state’s 30 million
acres of farm and ranchland, generally see a 20% to 75%
reduction in property taxes. … The proposed legislation
seeks to align the state’s renewable energy and groundwater
management goals. California’s Sustainable Groundwater
Management Act, or SGMA, requires users to bring groundwater
basins into balance within the next two decades.
In a place as dry as the desert city of Dubai, whenever they
can get rain, they’ll take it. United Arab Emirates authorities
will often even try to make it rain—as they did earlier this
week when the National Center of Meteorology dispatched planes
to inject chemicals into the clouds to try to coax some
showering. But this time they got much more than they
wanted. Dubai faced torrential downpours on Tuesday, with
flooding shutting down much of the city … The UAE government
media office said it was the heaviest rainfall recorded in 75
years and called it “an exceptional event.” More than a typical
year’s worth of water was dumped on the country in a single
day. Now, many people are pointing a finger at the “cloud
seeding” operations preceding the precipitation.
Santa Clara County residents could see higher water bills in
the upcoming year, as one water agency looks for ways to cover
costs. Valley Water, the region’s main water supplier, is
proposing raising groundwater production charges on cities and
private water retailers. The increase will be passed on to
household ratepayers through local water companies such as San
Jose Water. This could add $8.78 a month to customers’ bills in
the upcoming fiscal year. Valley Water is spending big to
fix the Anderson and Pacheco dams and other projects that hold
and protect the county’s water supply from climate change. The
board of directors is looking for more money amid a
multimillion-dollar structural deficit, putting residents on
the hook for the district’s losses.
The Wonderful Company, California-based maker of the popular
pomegranate juice POM, is the state’s second-largest user of
paraquat – a toxic herbicide banned in over 60 countries – a
new Environmental Working Group investigation finds.
Studies have found a strong connection between paraquat
exposure and an elevated risk of Parkinson’s disease. The
chemical has also been linked with non-Hodgkin lymphoma and
childhood leukemia. … Wonderful’s brands include POM
pomegranate juice, Landmark Vineyards wine and Fiji Water,
among many others. In 2021 alone, Wonderful sprayed more
than 56,000 pounds of paraquat on California fields where it
grows pistachios, almonds and pomegranates, according to state
and county records analyzed by EWG. … The herbicide can
remain in soil for years.
Record-breaking heat waves, severe floods and acute wildfires,
exacerbated by climate change, carry a colossal price tag: an
approximately 19% reduction in global income over just the next
26 years, a new study published Wednesday found. That financial
gut punch won’t just affect big governments and corporations.
According to the United Nations, the world is heading toward a
gain of nearly 3 degrees of global warming in the next century,
even with current climate policies and goals – and researchers
say individuals could bear the economic burden. The researchers
in Wednesday’s study, published in Nature, said financial pain
in the short-term is inevitable, even if governments ramp up
their efforts to tackle the crisis now.
From Sequoia Park to the old Tulare Lake bed, local authorities
recount the same story. A deluge of biblical proportions,
including heavy rain and storm runoff, in the past year in the
Kaweah, Kings and Tule basins has caused hundreds of millions
of dollars in damage to the region’s road and bridge
infrastructure. … Still a year later, government
agencies continue to struggle to repair the extensive damage
requiring federal funding to make it happen.
The U.S. has a long record of extracting resources on Native
lands and ignoring tribal opposition, but a decision by federal
energy regulators to deny permits for seven proposed hydropower
projects suggests that tide may be turning. As the U.S. shifts
from fossil fuels to clean energy, developers are looking for
sites to generate electricity from renewable sources. But in an
unexpected move, the Federal Energy Regulatory Commission
denied permits on Feb. 15, 2024, for seven proposed hydropower
projects in Arizona and New Mexico. The reason: These projects
were located within the Navajo Nation and were proposed without
first consulting with the tribe. FERC said it was “establishing
a new policy that the Commission will not issue preliminary
permits for projects proposing to use Tribal lands if the Tribe
on whose lands the project is to be located opposes the
permit.” -Written by Emily Benton Hite, Assistant
Professor of Sociology and Anthropology, Saint Louis
University; and Denielle Perry Associate, Professor

Nutrient (nitrogen [N] and phosphorus [P] chemistry)
downgradient from onsite wastewater treatment system (OWTS) was
evaluated with a groundwater study in the area surrounding
Elizabeth Lake, the largest of three sag lakes within the Santa
Clara River watershed of Los Angeles County, California.
Elizabeth Lake is listed on the “303 (d) Impaired Waters List”
for excess nutrients and is downgradient from more than 600
OWTS. The primary objective of this study was to develop a
conceptual hydrogeological model to determine if discharge from
OWTS is transported into shallow groundwater within the
Elizabeth Lake subwatershed and contributes nutrients to
Elizabeth Lake in excess of the total maximum daily load
limit.
After waiting 14 years, water rights protestants to a 2009
proceeding have filed a complaint against the State Water
Resources Control Board alleging it has given preferential
treatment to the Department of Water Resources (DWR) regarding
antiquated water rights claims. They also said the board failed
to implement state laws requiring the reasonable and equitable
development of water diversions and the protection of water
resources in the State. … The complaint alleges that DWR
has failed to comply with state water rights law requiring
water rights be timely put to full beneficial use; the
purpose of this requirement is to safeguard the public
interest.
The current water year, which began Oct. 1, has been wetter
than usual, with the Russian River watershed accumulating 119%
of the yearly average rainfall, totaling 49.38 inches since
October. In the past, we might have celebrated our good fortune
and watched lake levels rise only to watch much of it sent
downriver to the Pacific Ocean as reservoirs reached an
inflexible upper threshold. Today, we get to continue enjoying
that ample rainfall long after summer sunshine arrives. Grant
Davis With almost a decade of data under its belt, the Russian
River Forecast-Informed Reservoir Operations program has been
making great strides by demonstrating the viability of this
strategy to operate reservoirs more effectively using modern
technology and forecasting. -Written by Grant Davis, general manager of Sonoma
Water.
Kings County growers will face millions of dollars in fees and
a mandate to report groundwater pumping after California
officials voted unanimously today to put local agencies on
probation for failing to protect the region’s underground water
supply. The unprecedented decision is a first step that could
eventually lead to the state wresting control of a groundwater
basin in a severely depleted part of the San Joaquin
Valley. Before issuing the probation order, the State
Water Resources Control Board had repeatedly warned five
groundwater agencies in Kings County that their management plan
for the Tulare Lake basin is seriously deficient, failing to
rein in the dried-up wells, contaminated water and sinking
earth worsened by overpumping.
One of the largest dams built in the United States in the last
two decades is one year away from completion, a dam that will
help supply water to Northern Coloradans for decades to
come. The Chimney Hollow Reservoir project is
underway in the Foothills west of Loveland, and it’s expected
to be completed and retaining water by summer of 2025.
… Northern Colorado is one of the fastest growing
regions in the state.
The Metropolitan Water District plans to spend up to $250
million on four non-traditional water projects that, combined,
could supply up to 100,000 Southern California households over
the next few years. Wastewater recycling, rainwater reclamation
and transforming ocean water into drinking water are some of
the technologies that could get money in the coming wave of
funding from MWD. The Los Angeles-based wholesaler, which helps
transfer water from Northern California and the Colorado River
to 26 retail water districts in the Los Angeles region, has
spent about $700 million on smaller, non-traditional water
projects since launching its Local Resources Program in 1990.
The amounts announced Monday, April 15, represent some of MWD’s
biggest investments in water innovation to date.
San Francisco has been giving Seattle a run for its money on
the precipitation front. Since Jan. 1, nearly 18 inches of
rain has accumulated in San Francisco. Meanwhile, Seattle sits
at just 13 inches. This year is unusual. San Francisco
has been rainier than Seattle in just 16 of the past 50 years
through mid-April. In a normal year, San Francisco trails
Seattle by about 2.5 inches of precipitation on April
14. Annually, Seattle averages 16.5 inches more rainfall
than San Francisco and may still surpass San Francisco this
year. While 2024’s rainfall may seem topsy-turvy, it
fits expectations with El Niño, a global climate pattern that
has its biggest influence on West Coast storms from January
through April.
The troubled Chiquita Canyon Landfill in Castaic received a new
violation last week from a state water agency for pumping
untreated leachate water from the landfill into local waterways
that empty into the Santa Clara River. A violation letter dated
April 9 was sent to the landfill operators by the Los Angeles
Regional Water Quality Control Board, raising concerns that the
landfill’s wastewater may reach groundwater sources fed by the
river and used for drinking water.
