Water quality in California is regulated by several state
agencies, including the State Water Resources Control Board
(State Water Board) and its nine regional boards, which
enforce clean water laws and the Department of Public Health.
Water quality concerns are also often involved in disputes
over water rights, particularly in situations involving
endangered species or habitat.
The State Water Board administers the Clean Water Grant Program
that funds construction of wastewater treatment facilities. The
State Water Board also issues general permits for municipalities
and construction sites that try to prevent contaminants from
those sources from entering municipal storm sewers.
Drinking water standards and regulations are developed by federal
and state agencies to protect public health. In California, the
Department of Public Health administers the federal Safe
Drinking Water Act, which regulates drinking water quality in the
United States.
The US Environmental Protection Agency has put restrictions on
four pesticides to save endangered Pacific salmon and steelhead
species from extinction. The new mitigation measures, announced
Feb. 1, aim to protect 28 salmon species in Washington, Oregon,
and California from pesticide runoff and spray drift. The four
targeted pesticides are three herbicides—bromoxynil, prometryn,
and metolachlor—and the soil fumigant 1,3-dichloropropene. The
EPA put the measures in place after the National Marine
Fisheries Service found in 2021 that such restrictions are
needed to protect endangered and threatened salmon species. The
measures require no-spray vegetative buffers between waters
where salmon live and agricultural fields. They also require
retention ponds and vegetated drainage ditches. All of these
measures are intended to capture pesticides that otherwise
could seep into the water.
The State Water Resources Control Board will spend $34 million
for six projects to improve the water quality of the New River
and the Tijuana River along the U.S.-Mexico border. The New
River starts south of the city of Mexicali, and runs through
Calexico on the U.S. side of the border and through Imperial
County to the Salton Sea. The Tijuana River runs from Baja
California into San Diego. Both rivers are heavily polluted by
sewage, trash, industrial and agricultural waste, and other
sediment and pollutants.
The release of 64,000 gallons of untreated sewage prompted the
closures of several Los Angeles County beaches Wednesday,
public health officials said. A blocked main line led to the
sewage entering the storm drain system near Admiralty and
Palawan ways in Marina del Rey, the Los Angeles County
Department of Public Health said in a news release. The
blockage was cleared by Wednesday afternoon, but Mother’s Beach
in Marina del Rey, Venice City Beach and Dockweiler State Beach
were ordered closed. … The closures will remain in
effect until bacterial levels in daily water testing meet
health standards, the department said.
Much has been made of two drinking water pollutants recently:
PFAS and microplastics. We spoke with Jason Dadakis, executive
director of water quality and technical resources with the
Orange County Water District, to find out how worried we should
be. What are PFAS and microplastics, why are they in our water
supply, and why should we care? “PFAS” is an acronym for a
large family of manmade chemicals that all feature the
carbon-fluorine bond, one of the strongest bonds in nature.
They resist degradation in the environment, which is where they
get their nickname “forever chemicals.”
Researchers at Princeton Engineering have found a way to turn
your breakfast food into a new material that can cheaply remove
salt and microplastics from seawater. The researchers used egg
whites to create an aerogel, a lightweight and porous material
that can be used in many types of applications, including water
filtration, energy storage, and sound and thermal insulation.
Craig Arnold, the Susan Dod Brown Professor of Mechanical and
Aerospace Engineering and vice dean of innovation at Princeton,
works with his lab to create new materials, including aerogels,
for engineering applications.
Eating one freshwater fish caught in a river or lake in the
United States is the equivalent of drinking a month’s worth of
water contaminated with toxic “forever chemicals,” new research
said on Tuesday. The invisible chemicals, called PFAS, were
first developed in the 1940s to resist water and heat and are
now used in items such as non-stick pans, textiles, fire
suppression foams and food packaging. But the indestructibility
of PFAS, per- and polyfluoroalkyl substances, means the
pollutants have built up over time in the air, soil, lakes,
rivers, food, drinking water and even our bodies. There have
been growing calls for stricter regulation for PFAS, which have
been linked to a range of serious health issues including liver
damage, high cholesterol, reduced immune responses and several
kinds of cancer.
All legislation aimed at regulating toxic PFAS “forever
chemicals” died in the Democratic-controlled US Congress last
session as companies flexed their lobbying muscle and bills did
not gain enough Republican support to overcome a Senate
filibuster. … PFAS are a class of about 12,000
compounds used to make products resist water, stains and heat.
They are known as “forever chemicals” because they do not
naturally break down, and they have been linked to cancer, high
cholesterol, liver disease, kidney disease, fetal complications
and other serious health problems. The Environmental
Protection Agency this year found that virtually no level of
exposure to two types of PFAS compounds in drinking water is
safe, and public health advocates say the entire chemical class
is toxic and dangerous.
A test for federal Clean Water Act jurisdiction over waterways
and wetlands that is central to an EPA rule announced last week
will make the rule especially vulnerable to an upcoming US
Supreme Court ruling, water lawyers say. The Environmental
Protection Agency and the Army Corps of Engineers published
their final definition of “waters of the US,” or WOTUS, on Dec.
30—the latest iteration of a Clean Water Act regulation that
has shifted in each presidential administration since 2008. The
2023 rule, which will take effect 60 days after it is published
in the Federal Register, is based on a rule that was in effect
before 2015. It governs which surface waters are protected from
pollution by the federal government by determining if they are
“relatively permanent” or have a “significant nexus” with
larger navigable waterways.
Our 2022 Water Leaders class completed its year with a
report outlining policy recommendations for the Sacramento-San
Joaquin Delta Water Quality Control Plan update. The cohort of 20
up-and-coming leaders from various water-related

It’s not hard to find groundwater. “It’s everywhere,” said Kip
Solomon, a geology and geophysics professor at the University
of Utah. “There’s no place on earth where you can’t drill a
well and hit groundwater.” Groundwater makes up a little more
than 30% of the freshwater on earth, while nearly 70% is locked
up in glaciers and icecaps. Only a tiny percentage of the
planet’s freshwater supply is made up of freely flowing,
surface level water. What can be difficult, Solomon said, is
finding “water that is of good quality, that’s not too salty.
And it’s harder to find water where you can pump out large
quantities.” That makes understanding this critical
resource all the more important — especially in the
drought-stricken West where many communities, from Moab to
Cedar City to the Coachella Valley, California, rely on
underground aquifers.
The Arizona Department of Environmental Quality has initiated a
statewide effort to sample over 1,200 public water systems
across the state for 29 different kinds of a hazardous chemical
known as PFAS. The goal is to produce a detailed map
showing the presence of PFAS in drinking water supplies, the
first step toward cleaning up contaminated water sources. PFAS,
short for per- and polyfluoroalkyl substances, are a class of
manufactured chemicals that have been used since the late 1940s
in a wide variety of products and industries, and can now be
found globally in water and soil. A growing body of evidence
has shown that long-term exposure, even to low traces of these
chemicals, can cause severe health issues.
The U.S. Environmental Protection Agency on Dec. 30 released
the revised definition of the “Waters of the United States”
rule to redefine waters protected under the federal Clean Water
Act. This new rule will replace the Navigable Waters Protection
Rule. California Farm Bureau President Jamie Johansson
expressed his concerns on behalf of farmers, ranchers and
agricultural businesses in the state. “This rule will have a
substantial effect on our members and the ability of our
farmers and ranchers in California to continue to utilize their
land,” Johansson said. “We are particularly concerned about
small farms and ranches needing costly legal or consulting
expertise to farm ground they have already thoughtfully and
sustainably stewarded.”
Just days after rain left the city with flooding waters and
streets covered in debris, runoff is also leading to unsafe
swimming conditions along our coast. Right now, there are
currently four beach closures in our region: Imperial Beach
Shoreline, Tijuana Slough Shoreline, Silver Strand Shoreline,
and Coronado Shoreline. The San Diego Department of
Environmental Health and Quality warning beachgoers to stay
away until further testing. Along the Coronado shoreline
water contact warning signs line the sand, alerting beachgoers
to steer clear. … Ringing in the new year with moderate rain
and gusty winds has led to these south swell conditions and
urban runoff across the U.S. Mexico border raising bacteria
levels in ocean and bay water here at home.
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.”
Explore the lower Colorado River firsthand where virtually every drop of the river is allocated, yet demand is growing from myriad sources — increasing population, declining habitat, drought and climate change.
The 1,450-mile river is a lifeline to some 40 million people in the Southwest across seven states, 30 tribal nations and Mexico. How the Lower Basin states – Arizona, California and Nevada – use and manage this water to meet agricultural, urban, environmental and industrial needs is the focus of this tour.

Radically transformed from its ancient origin as a vast tidal-influenced freshwater marsh, the Sacramento-San Joaquin Delta ecosystem is in constant flux, influenced by factors within the estuary itself and the massive watersheds that drain though it into the Pacific Ocean.
Lately, however, scientists say the rate of change has kicked into overdrive, fueled in part by climate change, and is limiting the ability of science and Delta water managers to keep up. The rapid pace of upheaval demands a new way of conducting science and managing water in the troubled estuary.
Out of sight and out of mind to most
people, the Salton Sea in California’s far southeast corner has
challenged policymakers and local agencies alike to save the
desert lake from becoming a fetid, hyper-saline water body
inhospitable to wildlife and surrounded by clouds of choking
dust.
The sea’s problems stretch beyond its boundaries in Imperial and
Riverside counties and threaten to undermine multistate
management of the Colorado River. A 2019 Drought Contingency Plan for the
Lower Colorado River Basin was briefly stalled when the Imperial
Irrigation District, holding the river’s largest water
allocation, balked at participating in the plan because, the
district said, it ignored the problems of the Salton Sea.
Voluntary agreements in California
have been touted as an innovative and flexible way to improve
environmental conditions in the Sacramento-San Joaquin Delta
and the rivers that feed it. The goal is to provide river flows
and habitat for fish while still allowing enough water to be
diverted for farms and cities in a way that satisfies state
regulators.
This event explored the lower Colorado River where virtually every drop of the river is allocated, yet demand is growing from myriad sources — increasing population, declining habitat, drought and climate change.
The 1,450-mile river is a lifeline to 40 million people in the Southwest across seven states and Mexico. How the Lower Basin states – Arizona, California and Nevada – use and manage this water to meet agricultural, urban, environmental and industrial needs was the focus of this tour.
Innovative efforts to accelerate
restoration of headwater forests and to improve a river for the
benefit of both farmers and fish. Hard-earned lessons for water
agencies from a string of devastating California wildfires.
Efforts to drought-proof a chronically water-short region of
California. And a broad debate surrounding how best to address
persistent challenges facing the Colorado River.
These were among the issues Western Water explored in
2019, and are still worth taking a look at in case you missed
them.
It’s been a year since two devastating wildfires on opposite ends
of California underscored the harsh new realities facing water
districts and cities serving communities in or adjacent to the
state’s fire-prone wildlands. Fire doesn’t just level homes, it
can contaminate water, scorch watersheds, damage delivery systems
and upend an agency’s finances.
The majestic beauty of the Sierra
Nevada forest is awe-inspiring, but beneath the dazzling blue
sky, there is a problem: A century of fire suppression and
logging practices have left trees too close together. Millions of
trees have died, stricken by drought and beetle infestation.
Combined with a forest floor cluttered with dry brush and debris,
it’s a wildfire waiting to happen.
Fires devastate the Sierra watersheds upon which millions of
Californians depend — scorching the ground, unleashing a
battering ram of debris and turning hillsides into gelatinous,
stream-choking mudflows.
Summer is a good time to take a
break, relax and enjoy some of the great beaches, waterways and
watersheds around California and the West. We hope you’re getting
a chance to do plenty of that this July.
But in the weekly sprint through work, it’s easy to miss
some interesting nuggets you might want to read. So while we’re
taking a publishing break to work on other water articles planned
for later this year, we want to help you catch up on
Western Water stories from the first half of this year
that you might have missed.
Each day, people living on the streets and camping along waterways across California face the same struggle – finding clean drinking water and a place to wash and go to the bathroom.
Some find friendly businesses willing to help, or public restrooms and drinking water fountains. Yet for many homeless people, accessing the water and sanitation that most people take for granted remains a daily struggle.
Californians have been doing an
exceptional job
reducing their indoor water use, helping the state survive
the most recent drought when water districts were required to
meet conservation targets. With more droughts inevitable,
Californians are likely to face even greater calls to save water
in the future.
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:
Sixty percent of California’s developed water supply
originates high in the Sierra Nevada mountains. 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.
We headed into the foothills and the mountains to examine
water issues that happen upstream but have dramatic impacts
downstream and throughout the state.

For decades, cannabis has been grown
in California – hidden away in forested groves or surreptitiously
harvested under the glare of high-intensity indoor lamps in
suburban tract homes.
In the past 20 years, however, cannabis — known more widely as
marijuana – has been moving from being a criminal activity to
gaining legitimacy as one of the hundreds of cash crops in the
state’s $46 billion-dollar agriculture industry, first legalized
for medicinal purposes and this year for recreational use.
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.
A new study could help water
agencies find solutions to the vexing challenges the homeless
face in gaining access to clean water for drinking and
sanitation.
The Santa Ana Watershed Project
Authority (SAWPA) in Southern California has embarked on a
comprehensive and collaborative effort aimed at assessing
strengths and needs as it relates to water services for people
(including the homeless) within its 2,840 square-mile area that
extends from the San Bernardino Mountains to the Orange County
coast.

Algal blooms in rivers, creeks and
lakes are an increasing
occurrence in California, threatening human health and safety as
well as pets. Blue-green algal blooms (cyanobacteria) occur in
California during the summer months because hot temperatures
combined with low water levels stimulate growth. If there are
excess nutrients present in their environment, especially
nitrogen and phosphorus, algae populations grow at accelerated
rates, creating algal blooms.
Potable water, also known as
drinking water, comes from surface and ground sources and is
treated to levels that that meet state and federal standards for
consumption.
Water from natural sources is treated for microorganisms,
bacteria, toxic chemicals, viruses and fecal matter. Drinking
raw, untreated water can cause gastrointestinal problems such as
diarrhea, vomiting or fever.
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.
This 28-page report describes the watersheds of the Sierra Nevada
region and details their importance to California’s overall water
picture. It describes the region’s issues and challenges,
including healthy forests, catastrophic fire, recreational
impacts, climate change, development and land use.
The report also discusses the importance of protecting and
restoring watersheds in order to retain water quality and enhance
quantity. Examples and case studies are included.
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.
A 20-minute version of the 2008 public television documentary
Salt of the Earth: Salinity in California’s Central Valley. This
DVD is ideal for showing at community forums and speaking
engagements to help the public understand the complex issues
surrounding the problem of salt build up in the Central Valley
potential – but costly – solutions. Narrated by comedian Paul
Rodriquez.
California’s little-known New River has been called one of North
America’s most polluted. A closer look reveals the New River is
full of ironic twists: its pollution has long defied cleanup, yet
even in its degraded condition, the river is important to the
border economies of Mexicali and the Imperial Valley and a
lifeline that helps sustain the fragile Salton Sea ecosystem.
Now, after decades of inertia on its pollution problems, the New
River has emerged as an important test of binational cooperation
on border water issues. These issues were profiled in the 2004
PBS documentary Two Sides of a River.
As part of the historic Colorado
River Delta, the Salton Sea regularly filled and dried for
thousands of years due to its elevation of 237 feet below
sea level.
World-renowned for its crystal clear, azure water, Lake Tahoe
straddles the Nevada-California border, stretching 22 miles long
and 12 miles wide and hemmed in by Sierra Nevada peaks.
At 1,645 feet deep, Tahoe is the second-deepest lake in the
United States and the 10th deepest in the world. The iconic lake
sits 6,225 feet above sea level.
The continued effort to improve water quality and reduce nonpoint
source pollution will hinge largely on a little-known pollution
control strategy known as total maximum daily loads (TMDLs),
which describe the amount of a particular pollutant that a water
body can absorb on a daily basis while remaining safe for
wildlife and people. While by no means a comprehensive
explanation of all the factors surrounding this complex subject,
this issue of Western Water provides a snapshot of TMDLs and what
they mean for water quality, supply and reliability.
2002 marks the 30th anniversary of one of the most significant
environmental laws in American history, the Clean Water Act
(CWA). The CWA has had remarkable success, reversing years of
neglect and outright abuse of the nation’s waters. But challenges
remain as attention turns to the thorny issue of cleaning up
nonpoint sources of pollution.
This issue of Western Water examines the problem of perchlorate
contamination and its ramifications on all facets of water
delivery, from the extensive cleanup costs to the search for
alternative water supplies. In addition to discussing the threat
posed by high levels of perchlorate in drinking water, the
article presents examples of areas hard hit by contamination and
analyzes the potential impacts of forthcoming drinking water
standards for perchlorate.
This issue of Western Water examines the presence of mercury in
the environment and the challenge of limiting the threat posed to
human health and wildlife. In addition to outlining the extent of
the problem and its resistance to conventional pollution
remedies, the article presents a glimpse of some possible courses
of action for what promises to be a long-term problem.
This issue of Western Water examines PPCPs – what they are, where
they come from and whether the potential exists for them to
become a water quality problem. With the continued emphasis on
water quality and the fact that many water systems in the West
are characterized by flows dominated by effluent contributions,
PPCPs seem likely to capture interest for the foreseeable future.
This issue of Western Water examines the challenges facing state,
federal and tribal officials and other stakeholders as they work
to manage terminal lakes. It includes background information on
the formation of these lakes, and overviews of the water quality,
habitat and political issues surrounding these distinctive bodies
of water. Much of the information in this article originated at
the September 2004 StateManagement Issues at Terminal Water
Bodies/Closed Basins conference.
This issue of Western Water examines that process. Much
of the information is drawn from discussions that occurred at the
November 2005 Selenium Summit sponsored by the Foundation and the
California Department of Water Resources. At that summit, a
variety of experts presented findings and the latest activities
from areas where selenium is of primary interest.
This issue of Western Water looks at some of the issues
facing drinking water providers, such as compliance with
increasingly stringent treatment requirements, the need to
improve source water quality and the mission of continually
informing consumers about the quality of water they receive.
This Western Water looks at proposed new measures to deal with
the century-old problem of salinity with a special focus on San
Joaquin Valley farms and cities.
This printed issue of Western Water examines the Russian and
Santa Ana rivers – areas with ongoing issues not dissimilar to
the rest of the state – managing supplies within a lingering
drought, improving water quality and revitalizing and restoring
the vestiges of the native past.
This printed issue of Western Water examines
desalination – an issue that is marked by great optimism and
controversy – and the expected role it might play as an
alternative water supply strategy.
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 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.
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.
This printed issue of Western Water examines the issues
associated with the State Water Board’s proposed revision of the
water quality Bay-Delta Plan, most notably the question of
whether additional flows are needed for the system, and how they
might be provided.
This printed issue of Western Water looks at hydraulic
fracturing, or “fracking,” in California. Much of the information
in the article was presented at a conference hosted by the
Groundwater Resources Association of California.
This printed issue of Western Water features a
roundtable discussion with Anthony Saracino, a water resources
consultant; Martha Davis, executive manager of policy development
with the Inland Empire Utilities Agency and senior policy advisor
to the Delta Stewardship Council; Stuart Leavenworth, editorial
page editor of The Sacramento Bee and Ellen Hanak, co-director of
research and senior fellow at the Public Policy Institute of
California.
This issue of Western Water looks at the BDCP and the
Coalition to Support Delta Projects, issues that are aimed at
improving the health and safety of the Delta while solidifying
California’s long-term water supply reliability.
Drawn from a special stakeholder symposium held in September 1999
in Keystone, Colorado, this issue explores how we got to where we
are today on the Colorado River; an era in which the traditional
water development of the past has given way to a more
collaborative approach that tries to protect the environment
while stretching available water supplies.
This 30-minute documentary, produced in 2011, explores the past,
present and future of flood management in California’s Central
Valley. It features stories from residents who have experienced
the devastating effects of a California flood firsthand.
Interviews with long-time Central Valley water experts from
California Department of Water Resources (FloodSAFE), U.S. Army
Corps of Engineers, Bureau of Reclamation, Central Valley Flood
Management Program and environmental groups are featured as they
discuss current efforts to improve the state’s 150-year old flood
protection system and develop a sustainable, integrated, holistic
flood management plan for the Central Valley.
20-minute version of the 2012 documentary The Klamath Basin: A
Restoration for the Ages. This DVD is ideal for showing at
community forums and speaking engagements to help the public
understand the complex issues related to complex water management
disputes in the Klamath River Basin. Narrated by actress Frances
Fisher.
For over a century, the Klamath River Basin along the Oregon and
California border has faced complex water management disputes. As
relayed in this 2012, 60-minute public television documentary
narrated by actress Frances Fisher, the water interests range
from the Tribes near the river, to energy producer PacifiCorp,
farmers, municipalities, commercial fishermen, environmentalists
– all bearing legitimate arguments for how to manage the water.
After years of fighting, a groundbreaking compromise may soon
settle the battles with two epic agreements that hold the promise
of peace and fish for the watershed. View an excerpt from the
documentary here.
This 30-minute documentary-style DVD on the history and current
state of the San Joaquin River Restoration Program includes an
overview of the geography and history of the river, historical
and current water delivery and uses, the genesis and timeline of
the 1988 lawsuit, how the settlement was reached and what was
agreed to.
This 25-minute documentary-style DVD, developed in partnership
with the California Department of Water Resources, provides an
excellent overview of climate change and how it is already
affecting California. The DVD also explains what scientists
anticipate in the future related to sea level rise and
precipitation/runoff changes and explores the efforts that are
underway to plan and adapt to climate.
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.

Water truly has shaped California into the great state it is
today. And if it is water that made California great, it’s the
fight over – and with – water that also makes it so critically
important. In efforts to remap California’s circulatory system,
there have been some critical events that had a profound impact
on California’s water history. These turning points not only
forced a re-evaluation of water, but continue to impact the lives
of every Californian. This 2005 PBS documentary offers a
historical and current look at the major water issues that shaped
the state we know today. Includes a 12-page viewer’s guide with
background information, historic timeline and a teacher’s lesson.
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.
As the state’s population continues to grow and traditional water
supplies grow tighter, there is increased interest in reusing
treated wastewater for a variety of activities, including
irrigation of crops, parks and golf courses, groundwater recharge
and industrial uses.

conjunctive use. New in this 10th edition of the guide is a
section on the human need for water.
The 28-page Layperson’s Guide to California
Wastewater is an in-depth, easy-to-understand publication
that provides background information on the history of wastewater
treatment and how wastewater is collected, conveyed, treated and
disposed of today. The guide also offers case studies of
different treatment plants and their treatment processes.
Finding and maintaining a clean
water supply for drinking and other uses has been a constant
challenge throughout human history.
Today, significant technological developments in water treatment,
including monitoring and assessment, help ensure a drinking water
supply of high quality in California and the West.
The source of water and its initial condition prior to being
treated usually determines the water treatment process. [See also
Water Recycling.]
California’s 40 million residents, the farmers who produce $50
billion a year in agricultural commodities, the industry that
helps power the fifth-largest economy in the world and the
plants, fish and wildlife that are a vital part of the state’s
environment all depend on clean water to survive.
Wastewater management in California centers on the collection,
conveyance,
treatment, reuse and disposal of wastewater. This process is
conducted largely by public agencies, though there are also
private systems in places where a publicly owned treatment plant
is not feasible.
In California, wastewater treatment takes place through 100,000
miles of sanitary sewer lines and at more than 900 wastewater
treatment plants that manage the roughly 4 billion gallons of
wastewater generated in the state each day.
There are nine regional water quality control boards statewide.
The nine Regional Boards are semi-autonomous and are comprised of
seven part-time Board members appointed by the Governor and
confirmed by the Senate. Regional boundaries are based on
watersheds and water quality requirements are based on the unique
differences in climate, topography, geology and hydrology for
each watershed. Each Regional Board makes critical water quality
decisions for its region, including setting standards, issuing
waste discharge requirements, determining compliance with those
requirements, and taking appropriate enforcement actions.
The federal Safe Drinking Water Act sets standards for drinking
water quality in the United States.
Launched in 1974 and administered by the U.S. Environmental
Protection Agency, the Safe Drinking Water Act oversees states,
communities, and water suppliers who implement the drinking water
standards at the local level.
The act’s regulations apply to every public water system in the
United States but do not include private wells serving less than
25 people.
According to the EPA, there are more than 160,000 public water
systems in the United States.
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.
It may surprise some people to know that California is the fourth
largest producer of crude oil in the United States and has a long
history of oil exploration. Since the 1860s, wells in Kern County
and Southern California have been tapped for more than 500,000
barrels of oil each day.
For something so largely hidden from view, groundwater is an
important and controversial part of California’s water supply
picture. How it should be managed and whether it becomes part of
overarching state regulation is a topic of strong debate.
Is the water consumed by people everyday safe to drink or should
there be concern about unregulated contaminants, many of which
are the remnants of commonly used pharmaceutical and personal
care products?
For most people in the United States, clean, safe drinking water
is a given – a part of daily life that is assumed to be a
constant, readily accessible commodity. Underpinning that fact
are the vast, mostly unheralded efforts of the many people
throughout the country who work everyday to take the raw source
water from the environment and turn it into the safe drinking
water that makes life possible.
There may be no other substance in nature as vexing as selenium.
The naturally occurring trace element gained notoriety more than
20 years ago as it wreaked havoc among birds at the Kesterson
Reservoir in California’s Central Valley. The discovery of dead
and deformed birds sparked a widespread investigation that
revealed the pervasiveness of selenium throughout much of the
West; woven into the soil and rock of the landscape.
Most people take for granted the quality of their drinking water
and for good reason. Coinciding with America’s rapid urbanization
last century was the development of an extensive infrastructure
for the storage, treatment and delivery of water for generations
to come. The improvement in the quality of water provided by
water agencies has been so phenomenal that some of the best
tasting water in the world comes not from a plastic bottle, but
from the tap.
There’s danger lurking underground. The threat cannot be seen,
heard or felt immediately, but there it resides – in shallow
pockets of groundwater and deep, cold subterranean aquifers
situated hundreds of feet below the surface. The danger manifests
itself through the most vital human activity next to breathing,
the consumption of water. Experts know there is no such thing as
pure water. Microscopic bits of a host of elements that surround
us are present in the water we drink. They exist at levels that
are harmless, and in fact some of the constituents found in tap
water are beneficial to human health.
This year marks the 30th anniversary of one of the most
significant environmental laws in American history, the Clean
Water Act (CWA). The law that emerged from the consensus and
compromise that characterizes the legislative process has had
remarkable success, reversing years of neglect and outright abuse
of the nation’s waters.
The arrival of each storm brings more than rain and snow to
thirsty California. From the coastal redwoods to the streets of
Los Angeles, water flowing from hillsides and paved surfaces
carries with it a host of pollutants that befoul tributaries,
streams and rivers. The toll on the environment is measured in
closed beaches, reduced fish populations and, in some cases, a
lower quality of available water for human use. The sources of
pollution are sometimes easy to control with existing technology.
But in other cases, the ubiquitous nature of contaminants has
left regulators in a quandary over how to solve the problem.
Drinking water is the ultimate recycled resource. It is recycled
over years, centuries and millenniums. The water we use today is
the same supply with which civilization began. The water that
once coursed down the Ganges River or splashed into Julius
Caesar’s bathing pool may end up running from the tap in your
home.
Clean air vs. clean water sums up the controversy surrounding the
gasoline additive methyl tertiary butyl ether (MTBE), an
oxygenate designed to help fuel burn cleaner, reducing tailpipe
emissions. Since 1996, the year it was first used statewide on a
year-round basis, MTBE has reduced smog from motor vehicles by 15
percent, according to air quality officials. It’s as if 3.5
million cars have disappeared from the roads – no small feat in
the automobile – dependent Golden State.
