California’s Death Valley, the driest place in North America,
has hosted an ephemeral lake since late 2023. A NASA-led
analysis recently calculated water depths in the temporary lake
over several weeks in February and March 2024, demonstrating
the capabilities of the U.S.-French Surface Water and Ocean
Topography (SWOT) satellite, which launched in December 2022.
The analysis found that water depths in the lake ranged from
about 3 feet (1 meter) to less than 1.5 feet (0.5 meters) over
the course of about 6 weeks. This period included a series of
storms that swept across California, bringing record amounts of
rainfall.
As part of a $250 million commitment to support four water
supply projects in Southern California, Los Angeles will
receive $139 million over 25 years for its Groundwater
Replenishment Project in the San Fernando Valley, officials
announced on Monday, April 15. Earlier this month, the
Metropolitan Water District of Southern California’s Board of
Directors approved separate agreements with water agencies,
including the city of Los Angeles, as part of its Local
Resources Program. The Metropolitan Water District is a
state-established wholesaler that provides water for 19 million
people in six counties. The Local Resources Program aims to
provide economic incentives for water developed and produced
from groundwater clean-up, water recycling and seawater
desalination throughout the agency’s six-county service area.
A new lawsuit filed by public drinking water systems in
California against manufacturers of toxic “forever chemicals”
is among the first to cite new Biden administration regulations
that set strict limits for the chemicals in drinking water. The
Orange County Water District and more than a dozen other
California water utilities filed the lawsuit in Los Angeles
federal court on Friday against seven manufacturers of per- and
polyfluoroalkyl substances, or PFAS, including Dynax America
Corp. and Arkema Inc. The lawsuit accuses the manufacturers of
negligence and of creating a nuisance by contaminating water
with PFAS, and seeks money to remediate that contamination.
The International Boundary and Water Commission is again being
sued over water-quality permit violations that have led to
rampant sewage polluting San Diego County’s southernmost
shoreline. The San Diego Coastkeeper and Coastal Environmental
Rights Foundation on Thursday filed a lawsuit in federal court
against the U.S. arm of the IBWC and its contractor Veolia
Water North America-West, alleging violations of the Clean
Water Act.
Near the western tip of the Mojave Desert and a few miles west
of NASA’s Armstrong Flight Research Center, fields of
wildflowers painted the landscape yellow in spring 2024. On
April 9, the OLI (Operational Land Imager) on the Landsat 8
satellite acquired this image of fields of yellow wildflowers
blanketing Antelope Valley amid solar and wind farms. The day
after the image was acquired, the Antelope Valley California
Poppy Reserve reported that wildflowers were “popping,” but the
region’s famous poppies were not. Rangers at the reserve said
they also saw very few small poppy plants maturing, suggesting
an impressive poppy bloom is unlikely in the coming weeks.
Even though Pacific storms have become less frequent, as is
often the case in April, a new storm is brewing and will slice
across California just in time for the weekend, bringing areas
of rain, mountain snow and much cooler air, AccuWeather
meteorologists say. … A storm over the Gulf of Alaska will
drop southward just off the coast into Friday and will swing
toward California this weekend. … A few inches to
perhaps a foot of snow may fall over the high country of the
Sierra Nevada from the weekend storm.
President Biden plans to expand the perimeters of two national
monuments in California, protecting mountains and meadows in a
remote area between Napa and Mendocino as well as a rugged
stretch east of Los Angeles, two people familiar with the
administration’s plans said Thursday. The San Gabriel Mountains
National Monument and the Berryessa Snow Mountain National
Monument will each get new boundaries designed to protect land
of cultural significance to Native American tribes, as well as
biodiversity and wildlife corridors, said the people, who asked
not to be named because they were not authorized to discuss the
plans publicly.
As the burning of fossil fuels and other human activities
continue to increase the levels of carbon dioxide in the
atmosphere, the ocean is absorbing a large portion of the CO2,
which is making seawater more acidic. … And here’s one
important fact about ocean acidification: It’s not happening at
the same rate everywhere. The California coast is one of the
regions of the world where ocean acidification
is occurring the fastest. … In particular, effluent
discharged from coastal sewage treatment plants, which has high
nitrogen levels from human waste, has been shown to
significantly contribute to ocean acidification off the
Southern California coast.
Chiquita Canyon Landfill has drawn more than 10,000 complaints,
a number of lawsuits and calls for it to close from residents
and elected officials and is allegedly dumping untreated
stormwater into local waterways, according to a complaint
issued this week by state water officials. The L.A.
Regional Water Quality Control Board issued another violation
Tuesday against Chiquita Canyon Landfill, after Castaic and Val
Verde residents sent the agency numerous photos of the landfill
allegedly pumping from its stormwater basin into the local
waterway at night. Multiple photos were posted to local social
media groups as well.
Today, Congresswoman Norma Torres and Congressman David Valadao
– members of the House Appropriations Committee – announced the
introduction of the bipartisan Removing Nitrate and Arsenic in
Drinking Water Act. This bill would amend the Safe Drinking
Water Act to provide grants for nitrate and arsenic reduction,
by providing $15 million for FY25 and every fiscal year
thereafter. The bill also directs the Environmental
Protection Agency (EPA) to take into consideration the needs of
economically disadvantaged populations impacted by drinking
water contamination. The California State Water Resources
Control Board found the Inland Empire to have the highest
levels of contamination of nitrate throughout the state
including 82 sources in San Bernardino, 67 sources in Riverside
County, and 123 sources in Los Angeles County.
Pasadena Water and Power (PWP) has launched a new multi-year
campaign called “The Ripple Effect” aimed at promoting water
sustainability and resilience in the community. Acting General
Manager David Reyes urged all PWP customers to become local
water stewards for Pasadena and the region by participating
in the campaign. “We invite every member of our
community to embrace their role as local water stewards,” said
Reyes. “Each one of us holds a vital place in shaping
Pasadena’s water future.” About one-third of
Pasadena’s water supply comes from local groundwater, with the
remaining two-thirds imported from other sources. PWP
emphasized that understanding where the community’s water comes
from helps foster a greater appreciation for
this critical resource.
Nearly half of US prisons draw water from sources likely
contaminated with toxic PFAS “forever chemicals”, new research
finds. At least around 1m people incarcerated in the US,
including 13,000 juveniles, are estimated to be housed in the
prisons, and they are especially vulnerable to the dangerous
chemicals because there is little they can do to protect
themselves, said Nicholas Shapiro, a study co-author at the
University of California in Los Angeles.
A first-of-its-kind report has estimated that Los Angeles
County must invest billions of dollars through 2040 to protect
residents from worsening climate hazards, including extreme
heat, increasing precipitation, worsening wildfires, rising sea
levels and climate-induced public health threats. The report,
published this week by the nonprofit Center for Climate
Integrity, identified 14 different climate adaptation measures
that authors calculated would cost L.A. taxpayers at least
$12.5 billion over the next 15 years. … To mitigate
these impacts, the county must expand its stormwater drainage
infrastructure by installing bioswales, porous pavement and
other opportunities for stormwater to seep into the ground, the
report found.
The Department of the Interior announced the Yuma East Wetlands
will receive $5 million to upgrade infrastructure to ensure the
continued existence of the marshes for future
generations. There will be improvements that include
designing and replacing the system used to move water around
the wetlands. Pumps currently fueled by diesel with
electrical pumps will be replaced, concrete canals will be
extended and electrical power will be brought to the
conservation area to allow for technology updates. The
Yuma East Wetlands is used by the community for public
recreation and it also provides habitat for wildlife including
endangered species.
Years ago, in a moment of despair over the utter dead-end that
solving the Tijuana River sewage crisis seemed to be, I asked
U.S. officials why we don’t just cross the border and start
fixing broken pipes in Mexico. Nations can’t just cross
each other’s borders like that, MacKenzie, the kindly federal
official told me. At least, they shouldn’t. It would be a rude
mistake. Mexico could consider such federal intrusion without
permission as an act of war. But President Joe Biden’s pick to
rein in cross-border sewage spills has found a way to leverage
her relationships with Mexico to encourage more collaborative
U.S. involvement. Maria-Elena Giner announced to reporters
during a press conference last week that the International
Boundary and Water Commission (the binational agency that deals
with cross-border water issues) will start monthly inspections
of a key sewage pump and trash shredder in Tijuana that feeds
wastewater into San Diego for treatment. -Written by MacKenzie Elmer, Voice of San Diego
reporter.
Los Angeles Department of Water & Power (DWP) and Mono Lake
Committee staff met this morning at the shore of Mono Lake to
conduct the annual joint reading of the surface elevation of
Mono Lake. The consensus is that the lake stands at 6,383.70
feet above mean sea level which means that Mono Lake is only
halfway to the 6,392-foot elevation level mandated by the
California State Water Resources Control Board 30 years ago to
resolve ecological, wildlife, economic, Tribal, public trust,
and air quality harms caused by the lowering of Mono
Lake. Today’s lake level triggers an important choice for
DWP: Will the Department choose a nearly fourfold increase in
diversions (16,000 acre-feet), or will it choose to leave
exports unchanged (4,500 acre-feet) and preserve the lake level
gains of the record-wet winter of 2023?
The start of April means that California’s rainy season is
coming to an end. Things are looking pretty good this year, but
there are some caveats. The snowpack across the Sierra Nevada
and the Colorado River Basin — both critical stores of water —
is hovering slightly above average, though it’s nowhere near
what we saw last winter. … It’s looking unlikely, as our
reservoirs are quite full and we’ve had a good showing of
snow. “We pulled back on restrictions last year, however,
we’re telling people to use their common sense,” said Adel
Hagekhalil, CEO of the Metropolitan Water District of Southern
California. The public agency will neither be drawing from
or putting water into storage, though that’ll change if the
allocation increases. According to Hagekhalil, the MWD has
enough water to help Southern California get through the next
three years.
An elected member of a Ventura County water board has pleaded
guilty to a felony charge of stealing water for his Oxnard
farm. Daniel Naumann, 66, admitted to one count of grand theft
of water, Ventura County District Attorney Erik Nasarenko said
in a Friday news release. As part of his plea agreement,
five other felony charges will be dropped, the Ventura
County Star reports. Naumann,
a Camarillo resident who is owner and operator of
Naumann Family Farms, was an elected board member of the United
Water Conservation District and an alternate board member of
the Fox Canyon Groundwater Management Agency. … Despite
those roles, Naumann took nearly $30,000 in water between 2019
and 2021 using “diversion bypasses [that] were installed on two
commercial water pumps that irrigated Naumann’s crops,” the
release stated.
After another spate of late-spring rain, Los Angeles
County public health officials are warning people to stay
out of the water until at least Wednesday. The Department
of Public Health issued an ocean water quality rain advisory
for all Los Angeles County beaches due to the stormy weather.
… The warning stretches the entire LA coastline.
As a homeowner, you invest a great deal of time, money, love,
imagination, and hard work into your house and property.
Of course, you hope nothing will go seriously wrong. Still, you
purchase homeowner’s insurance to give you peace of mind and to
ensure you’re financially protected if your home and belongings
are damaged by unpredictable events such as fire, vandalism,
theft, or storms. Today, climate change is causing
increasingly erratic weather patterns. Natural disasters,
including severe storms and wildfires, are becoming more
frequent and devastating. In 2023, nine “atmospheric
rivers” pummeled the western United States, dumping record
amounts of rain and snow. According to the National
Environmental Satellite, Data, and Information Service, more
than 32 trillion gallons of water drenched California, racking
up $4.6 billion in damages. -Written by John Petrov, a contractor and public
insurance adjuster with over 25 years of experience in the
