Stormwater runoff has emerged as a primary water quality issue.
In urban areas, after long dry periods rainwater runoff can
contain accumulations of pollutants. Stormwater does not go into
the sewer. Instead, pollutants can be flushed into waterways with
detrimental effects on the environment and water quality.
In response, water quality regulators use a range of programs to
reduce stormwater pollution including limiting the amount of
excess runoff and in some cases recapturing freshwater as well.
Palo Alto’s bioreactor towers are aging out, like a lot of the
clean water infrastructure constructed around the Bay Area in
the 1950s-1970s. Recent wind gusts, swirling around the edges
of February’s atmospheric river storms, have not been friendly
to the towers either. On a March visit to the Palo Alto
Regional Water Quality Control Plant, which treats 18 million
gallons of wastewater every day, I could see a big chunk
missing from the wall of one rusty cauldron and tumbleweeds
caught in the metalwork. Elsewhere on the 25-acre site,
the plant’s facilities are visibly undergoing a $193 million
overhaul. The overhaul will help the plant meet increasing
regulatory limits on the amount of nitrogen that dischargers
can pipe into the shallows of San Francisco Bay.
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.
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.
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.
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.
The California Department of Transportation (Caltrans) begins
construction this month to install a trash capture device along
northbound State Route 99, preventing trash in storm water
runoff from entering the Tuolumne River at Zeff Road. The trash
capture system will be located at the inlet of two existing
culverts on the southeast side of SR-99 and the Tuolumne River,
a location identified as a significant trash generating area.
The project will help the department achieve zero trash from
stormwater discharge into the lower reaches of the Tuolumne
River. It is consistent with the Caltrans’ Statewide Trash
Implementation plan and in compliance with the State Water
Resource Control Board water quality objectives for trash
pollutants.
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.
Marin County and Novato are disputing a state water board’s
contention that they are doing too little to prevent the
discharge of fecal bacteria into the Petaluma River. The San
Francisco Bay Regional Water Quality Board notified both the
county and Novato in January that they are out of compliance
with a program that it adopted in 2019 to reduce the level of
fecal bacteria in the river. Both jurisdictions, however,
contend that they are not required to comply with the program
because the scheme has not yet been incorporated into their
municipal storm sewer system permits, which are issued by the
State Water Resources Control Board.
Five possible alternatives to the tire antidegradant 6PPD have
been identified, following a comprehensive preliminary analysis
completed by a consortium of 30 tire manufacturers March 25.
…Gatorade, mayonnaise and Fireball bottles, soccer and golf

Rosa Creek], but all over [Sonoma County]. … Despite
calls from environmentalists, legislators and scientists,
plastic has become more prevalent, not less.
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.
A special workshop on the binational sewage crisis was held
Wednesday in Imperial Beach. The meeting featured a panel of
experts from various government agencies and academic
institutions. Dozens of concerned residents gathered at the
special council workshop addressing the ongoing sewage crisis.
They heard from the International Boundary and Water Commission
shed light on cross-border sewage flows. … Scripps
Institution of Oceanography offered valuable insights into the
environmental impact of sewage contamination, while SDSU School
of Public Health discussed risks associated with chemical and
biological pollutants in water, air, and soil.
Fishers are fighting tire companies’ attempt to dismiss an
Endangered Species Act suit over the use of a rubber additive
known as 6PPD, which harms salmon, telling a California federal
judge the companies are trying to delay accountability…
Today, legislation to protect California’s iconic salmon and
steelhead trout authored by Assemblymember Diane Papan (D-San
Mateo) was approved by the Assembly Committee on Transportation
with a bipartisan vote. The S.A.L.M.O.N Act (Stormwater
Anti-Lethal Measures for Our Natives Act), would mandate the
development and implementation of a regional strategy by the
Department of Transportation (Caltrans) to eliminate (a
contaminant from tire rubber) from stormwater discharges
into specified salmon and steelhead trout-bearing surface
waters of the state.
Years after a massive spill at a Los Angeles water treatment
facility dumped millions of gallons of raw sewage into the
Pacific, officials with the U.S. Environmental Protection
Agency have ordered several improvements at the plant to help
prevent another such disaster, even when facing more intense
storms from a changing climate. The administrative order of
consent, issued this month, requires the Hyperion Water
Reclamation Plant in Playa del Rey to make significant fixes to
its operations and infrastructure, including improving
monitoring systems and overflow channels, after the federal
agency’s review of the 2021 spill. The agreement, between the
EPA and the Los Angeles Sanitation and Environment division,
mandates the updates be implemented by the end of 2025, though
some are required to be completed as soon as within 30 days,
according to the order.
When heavy rain overwhelms wastewater treatment plants in San
Francisco, causing stormwater to overflow onto streets and
into the bay, sewage is an unfortunate part of the mix.
After heavy rain, the largest recipient of the potent brew of
stormwater and sewage in the city is Mission Creek — a
channel to the bay that is home to houseboats, walking trails
and a kayak launch. At Mission Creek, Islais Creek, another
channel at India Basin, and a few locations in between, the
city discharges 1.2 billion gallons of “combined sewer
discharges” in a typical year, according to the environmental
group S.F. Baykeeper, which has notified the city it intends to
sue over how such discharges impact the environment. A large
portion of the combined sewer overflows — which SFPUC said
are composed of 94% treated stormwater and 6% treated
wastewater — is making its way without basic treatment
into the bay during storms, according to S.F. Baykeeper.
Still water in the Tijuana River Valley reflects the chirping
birds who live there, giving the impression it is as nature
made it — until you see the floating trash and smell the
stagnant, polluted water. For decades, activists tried to clean
up the Tijuana River’s watershed as it flowed from Tijuana into
San Diego’s coastal waters, which are contaminated with both
human and industrial waste. A recent study from the Scripps
Institution of Oceanography found that coastal pollution is
also transferring to the air. “This is nothing short of an
environmental and public health crisis, and it has been made
worse by the fact that California companies are part of the
problem,” said State Senator Steve Padilla Monday, while
announcing SB 1178, a bill to address cross-border pollution.
It was exactly the sort of deluge
California groundwater agencies have been counting on to
replenish their overworked aquifers.
The start of 2023 brought a parade of torrential Pacific storms
to bone dry California. Snow piled up across the Sierra Nevada at
a near-record pace while runoff from the foothills gushed into
the Central Valley, swelling rivers over their banks and filling
seasonal creeks for the first time in half a decade.
Suddenly, water managers and farmers toiling in one of the
state’s most groundwater-depleted regions had an opportunity to
capture stormwater and bank it underground. Enterprising agencies
diverted water from rushing rivers and creeks into manmade
recharge basins or intentionally flooded orchards and farmland.
Others snagged temporary permits from the state to pull from
streams they ordinarily couldn’t touch.
On average, more than 60 percent of
California’s developed water supply originates in the Sierra
Nevada and the southern spur of the Cascade Range. Our water
supply is largely dependent on the health of our Sierra forests,
which are suffering from ecosystem degradation, drought,
wildfires and widespread tree mortality.
This tour ventured into the Sierra to examine water issues
that happen upstream but have dramatic impacts downstream and
throughout the state.
Blasted by sun and beaten by waves,
plastic bottles and bags shed fibers and tiny flecks of
microplastic debris that litter the San Francisco Bay where they
can choke the marine life that inadvertently consumes it.
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.
Although Santa Monica may be the most aggressive Southern California water provider to wean itself from imported supplies, it is hardly the only one looking to remake its water portfolio.
In Los Angeles, a city of about 4 million people, efforts are underway to dramatically slash purchases of imported water while boosting the amount from recycling, stormwater capture, groundwater cleanup and conservation. Mayor Eric Garcetti in 2014 announced a plan to reduce the city’s purchase of imported water from Metropolitan Water District by one-half by 2025 and to provide one-half of the city’s supply from local sources by 2035. (The city considers its Eastern Sierra supplies as imported water.)
Imported water from the Sierra
Nevada and the Colorado River built Southern California. Yet as
drought, climate change and environmental concerns render those
supplies increasingly at risk, the Southland’s cities have ramped
up their efforts to rely more on local sources and less on
imported water.
Far and away the most ambitious goal has been set by the city of
Santa Monica, which in 2014 embarked on a course to be virtually
water independent through local sources by 2023. In the 1990s,
Santa Monica was completely dependent on imported water. Now, it
derives more than 70 percent of its water locally.
Farmers in the Central Valley are broiling about California’s plan to increase flows in the Sacramento and San Joaquin river systems to help struggling salmon runs avoid extinction. But in one corner of the fertile breadbasket, River Garden Farms is taking part in some extraordinary efforts to provide the embattled fish with refuge from predators and enough food to eat.
And while there is no direct benefit to one farm’s voluntary actions, the belief is what’s good for the fish is good for the farmers.
Sixty percent of California’s developed water supply
originates high in the Sierra Nevada mountains. Our water

As we continue forging ahead in 2018
with our online version of Western Water after 40 years
as a print magazine, we turned our attention to a topic that also
got its start this year: recreational marijuana as a legal use.
State regulators, in the last few years, already had been beefing
up their workforce to tackle the glut in marijuana crops and
combat their impacts to water quality and supply for people, fish
and farming downstream. Thus, even if these impacts were perhaps
unbeknownst to the majority of Californians who approved
Proposition 64 in 2016, we thought it important to see if
anything new had evolved from a water perspective now that
marijuana was legal.
California voters may experience a sense of déjà vu this year when they are asked twice in the same year to consider water bonds — one in June, the other headed to the November ballot.
Both tackle a variety of water issues, from helping disadvantaged communities get clean drinking water to making flood management improvements. But they avoid more controversial proposals, such as new surface storage, and they propose to do some very different things to appeal to different constituencies.

Microplastics – plastic debris
measuring less than 5 millimeters – are an
increasing water quality concern. Entering the water as
industrial microbeads or as larger plastic litter that degrade
into small pellets, microplastics come from a variety of
consumer products.
Point sources release pollutants from discrete conveyances, such
as a discharge pipe, and are regulated by federal and state
agencies. The main point source dischargers are factories and
sewage treatment plants, which release treated
wastewater.
Problems with polluted stormwater and steps that can be taken to
prevent such pollution and turn what is often viewed as
“nuisance” runoff into a water resource is the focus of this
publication, Stormwater Management: Turning Runoff into a
Resource. The 16-page booklet, funded by a grant from the State
Water Resources Control Board, includes color photos and
graphics, text explaining common stormwater pollutants and
efforts to prevent stormwater runoff through land use/
planning/development – as well as tips for homeowners to reduce
their impacts on stormwater pollution.
This card includes information about the Colorado River, who uses
the river, how the river’s water is divided and other pertinent
facts about this vital resource for the Southwest. Beautifully
illustrated with color photographs.

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.
This 7-minute DVD is designed to teach children in grades 5-12
about where storm water goes – and why it is so important to
clean up trash, use pesticides and fertilizers wisely, and
prevent other chemicals from going down the storm drain. The
video’s teenage actors explain the water cycle and the difference
between sewer drains and storm drains, how storm drain water is
not treated prior to running into a river or other waterway. The
teens also offer a list of BMPs – best management practices that
homeowners can do to prevent storm water pollution.
The 28-page Layperson’s Guide to Water Rights Law, recognized as
the most thorough explanation of California water rights law
available to non-lawyers, traces the authority for water flowing
in a stream or reservoir, from a faucet or into an irrigation
ditch through the complex web of California water rights.
The 24-page Layperson’s Guide to Integrated Regional Water
Management (IRWM) is an in-depth, easy-to-understand publication
that provides background information on the principles of IRWM,
its funding history and how it differs from the traditional water
management approach.
For all the benefits of precipitation, stormwater also brings
with it many challenges.
In urban areas, after long dry periods rainwater runoff can
contain heavy accumulations of pollutants that have built up over
time. For example, a rainbow like shine on a roadway puddle can
indicate the presence of oil or gasoline. Stormwater does not go
into the sewer. Instead, pollutants can be flushed into waterways
with detrimental effects on the environment and water quality.
Lake Tahoe is one of the world’s most beautiful yet vulnerable
lakes. Renowned for its remarkable clarity, Tahoe straddles the
Nevada-California border, stretching 22 miles long and 12 miles
wide in a granitic bowl high in the Sierra Nevada.
Tahoe sits 6,225 feet above sea level. Its deepest point is 1,645
feet, making it the second-deepest lake in the nation, after
Oregon’s Crater Lake, and the tenth deepest in the world.
This printed issue of Western Water discusses several
flood-related issues, including the proposed Central Valley Flood
Protection Plan, the FEMA remapping process and the dispute
between the state and the Corps regarding the levee vegetation
policy.
This printed issue of Western Water discusses low
impact development and stormwater capture – two areas of emerging
interest that are viewed as important components of California’s
future water supply and management scenario.
Growth may have slowed in California, but advocates of low impact
development (LID) say the pause is no reason to lose sight of the
importance of innovative, low-tech management of stormwater via
incorporating LID aspects into new projects and redevelopment.
This printed issue of Western Water, based on presentations
at the November 3-4, 2010 Water Quality Conference in Ontario,
Calif., looks at constituents of emerging concerns (CECs) – what
is known, what is yet to be determined and the potential
regulatory impacts on drinking water quality.
This issue of Western Water examines the continuing practice of
smart water use in the urban sector and its many facets, from
improved consumer appliances to improved agency planning to the
improvements in water recycling and desalination. Many in the
water community say conserving water is not merely a response to
drought conditions, but a permanent ethic in an era in which
every drop of water is a valuable commodity not to be wasted.
