… EPA Administrator Lee Zeldin has championed fossil fuels
and the rollback of major clean air and water rules. His
history with PFAS is more nuanced; during his time as a New
York congressman, he supported legislation to regulate forever
chemicals in drinking water. … Zeldin has offered clues
about what the EPA could do. The agency estimated the rule
would cost about $1.5 billion annually and Zeldin said recently
that communities struggling to afford a fix for PFAS that are
just above the standard might be handled differently than
wealthy places with lots of it. … On Monday, the EPA
said it will establish an agency lead for PFAS, develop
wastewater limits for PFAS manufacturers and investigate
sources that pose an immediate danger to drinking water, among
other actions.
Despite advances in wastewater treatment, tiny plastic
particles called microplastics are still slipping through,
posing potential health and environmental hazards, according to
new research from The University of Texas at Arlington. …
(W)hen a plastic item reaches the end of its useful life, it
never truly disappears. Instead, it breaks down into smaller
and smaller pieces called microplastics—particles five
millimeters or less, about the width of a pencil eraser—that
end up in our soil and water. “What our systematic literature
review found is that while most wastewater treatment facilities
significantly reduce microplastics loads, complete removal
remains unattainable with current technologies,” said Un-Jung
Kim, assistant professor of earth and environmental sciences at
UT Arlington and senior author of the study published in
Science of the Total Environment.
… While the U.S. Environmental Protection Agency has changed
directions on several environmental subjects since President
Donald Trump took office, PFAS regulations are not yet among
those. Indeed, the Biden Administration EPA’s PFAS Strategic
Roadmap still is posted on the EPA’s website – at least for now
– and the EPA has not reported in two cases the positions it
will take on judicial challenges to final Biden-era PFAS
regulations. Thus, although those regulations are under
challenge, they are in effect, they have not been stayed, and
they are having impacts in the regulated community. The
EPA’s April 2024 PFAS maximum contaminant levels (MCLs) under
the Safe Drinking Water Act will affect drinking water systems,
of course. More broadly, they also will affect groundwater
cleanups as the low MCL values become integrated into screening
levels, risk analyses, and remediation levels.
Outside of major cities like Fresno and Clovis, drinking-water
quality for San Joaquin Valley residents can be dicey. The
Valley is full of examples of rural water systems failing to
either produce enough supply or deliver fresh water that is not
tainted by contaminants, be they manufactured, like farming
chemicals, or naturally occurring elements in local soils like
arsenic. … Now, Rep. David Valadao, a Republican from
Hanford, is teaming up with Rep. Norma Torres, a Democratic
legislator from Southern California, on a new bill that would
amend the federal Safe Drinking Water Act by adding a special
focus on nitrate and arsenic pollution in groundwater. The
amendment would authorize the federal government to allocate
$15 million a year in grants to clean up failing water systems
in rural communities.
We have previously written on the evolving risks associated
with PFAS—also known as “forever chemicals”—and their
implications for policyholders navigating environmental
liabilities involving both PFAS and PFAS-related chemicals
(i.e., fluorinated chemicals that do not fit the definition of
PFAS). Our prior analyses explored coverage strategies and
regulatory enforcement trends. With regulatory activity and
litigation continuing to accelerate, we are circling back to
provide an updated look at the regulatory and legal landscape
surrounding PFAS, including recent federal developments,
insurer responses and practical guidance for policyholders
navigating this complex and high-stakes area. … Since our
last insurance roundup in October 2023, there have been
significant developments in PFAS regulation, litigation and
insurance coverage about which policyholders should be aware.
This blog post provides an inexhaustive overview of some of the
more significant developments.
… At the beginning of the 20th century, Frederick McKay, a
young dentist in Colorado Springs, noticed that his patients’
teeth showed unsightly browning — now known as fluorosis, a
consequence of exposure to too much fluoride. At the same time,
those patients’ teeth were far more resistant to dental decay
than those of people in nearby towns, whose teeth looked
better. … As for natural contamination of the kind that
Colorado Springs experienced, it’s estimated that more than
100,000 people in the United States get their water from wells
with naturally excessive fluoride levels. You’d think that the
folks calling to end fluoridation would also be unveiling a
comprehensive plan to help people make sure their private water
sources are safe. Yet Kennedy has not done so. Why not? A
better question might be why now? Why the sudden urge to talk
about fluoride? I think the answer may lie somewhere quite far
afield. In Texas, actually. -Written by Zeynep Tufekci, a professor of sociology and
public affairs at Princeton University and a New York Times
Opinion columnist.
New research has identified hotspots in the US with concerning
levels of water quality and poor access to clean drinking
water, revealing that Mississippi, Pennsylvania, Arizona, and
Washington had the most water quality violations across the
board. The paper, published Tuesday in the journal Risk
Analysis, also developed county-level scores across most of the
country for unequal access to safe and clean drinking water,
finding that eight of the 10 counties with the worst “water
injustice” scores were in Mississippi, with the other two in
Texas and South Dakota. … “You can see some pretty stark
differences between states,” said study lead author Alex Segrè
Cohen, a social scientist at the University of Oregon. In
Arizona, Mississippi, and Pennsylvania, “almost every county
has high water violation scores,” she said.
… Studies suggest that PFAS has contaminated almost 50% of
the U.S. tap water supply. These chemicals are linked to a
growing list of health risks, including cancers and chronic
diseases. Many global institutions have recently taken
regulatory action. The U.S. Environmental Protection Agency
(EPA) proposed stringent limits for PFAS in drinking water.
… Beyond drinking water, recent studies expose another
major PFAS concern: wastewater and sludge. Treated wastewater,
often considered safe for reuse, has been found to still carry
significant levels of PFAS. Even more concerning is the
widespread practice of using treated sewage sludge as farm
fertilizer. The EPA has warned that PFAS in sludge can
contaminate crops, soil, and groundwater, creating a direct
pathway from industrial chemical waste to the food we
eat. … The question isn’t whether businesses should act,
it’s whether they can afford not to.
Health and Human Services Secretary Robert F. Kennedy Jr. has
gone after fluoride in drinking water, a move that medical
experts widely disagree with. Water fluoridation has been
proven to be so effective at preventing tooth decay that the
Centers for Disease Control and Prevention (CDC) named it one
of the 10 greatest public health achievements of the 20th
century, a time during which Americans’ life expectancies rose
by 30 years. “Fluoride has been studied extensively for decades
and is considered safe and effective at recommended levels,”
cosmetic dentist Dr. James Heaton tells USA TODAY. “While some
debates focus on the ethics of water fluoridation or potential
health concerns, the overwhelming consensus from the American
Dental Association, CDC and World Health Organization is that
fluoride is a critical tool in preventing tooth decay.” Here’s
what licensed medical experts want you to know about fluoride.
Tens of millions of Americans have likely consumed drinking
water containing cancer-causing chemicals that form when
livestock manure and other organic substances end up in public
water sources, according to a new analysis. Thousands of
industrial-scale farms across the country spray manure from
livestock onto farm or other lands, which then runs off into
waterways. When water utilities disinfect water using chlorine
and other chemicals, the process interacts with manure runoff
to create a byproduct known as trihalomethanes, or TTHMs, which
have been found to cause birth defects and cancers. A new
analysis by the environmental watchdog organization
Environmental Working Group (EWG) found that, between 2019 and
2023, unsafe levels of TTHMs ended up at least once in each of
nearly 6,000 community water systems across 49 states and
Washington, DC affecting an estimated 122 million people.
Legislation re-introduced by U.S. Sen. Mark Kelly (D-Kelly) and
a group of bipartisan lawmakers would ramp up testing and
treatment of PFAS contamination in private wells. PFAS are a
group thousands of human-made chemicals used in industrial and
consumer goods. Exposure has linked to health issues like
cancer. The legislation would allow states to use $5 billion
from the Bipartisan Infrastructure Law. Kelly says the change
will help ensure funding reaches communities that rely on those
wells — like those in rural and small areas. Funding provided
by the Bipartisan Infrastructure Law earmarked for water
contamination did originally include private wells, but, Kelly
says, not all communities ended up having access.
Millions of people across the United States could be drinking
water contaminated with dangerous levels of substances created
when utilities disinfect water tainted with animal manure and
other pollutants, according to a report released Thursday. An
analysis of testing results from community water systems in 49
states found that nearly 6,000 such systems serving 122 million
people recorded an unsafe level of chemicals known as
trihalomethanes at least once during testing from 2019 to 2023.
… New York, Oklahoma, California and Illinois followed Texas
with hundreds of water systems in each of those states showing
higher-than-allowed levels of TTHMs during the testing period,
the EWG report found. More than 64.5 million people are served
by 3,170 systems in the ten states that had the most
violations.
After years of struggling with poor water quality and aging
facilities, Governor Gavin Newsom today announced the
completion of a new water system for the City of Needles in
eastern San Bernardino County. This system will ensure reliable
access to safe drinking water for Needles’ 5,000 residents.
Today’s announcement of the new clean water system in Needles
furthers the state’s goal to provide all Californians with
clean and safe drinking water. Since 2019, thanks to state
efforts, the number of Californians without safe drinking water
has been reduced by half, from 1.6 million to about 800,000
people.
The U.S. Department of Health and Human Services will be
reconvening an independent panel of health experts to make a
new recommendation on putting fluoride in drinking water, a
spokesperson said on Monday. The use of the mineral, which is
added to water to strengthen tooth enamel and promote dental
health, has been a hot-button political issue in some states
for decades. ”HHS is reconvening the Community Preventive
Services Task Force to study and make a new recommendation on
fluoride,” an HHS spokesperson said. The statement
followed an Associated Press report quoting Secretary of Health
and Human Services Robert F. Kennedy Jr. saying at an event in
Salt Lake City, Utah, that he plans to tell the Centers for
Disease Control and Prevention to stop recommending fluoride in
drinking water.
The Trump administration is considering rolling back a major
Biden-era regulation on “forever chemicals” in drinking water,
a move that could leave people more exposed to the substances
linked to cancer, high blood pressure and fertility problems.
But any attempt to weaken the rule would run into a formidable
statutory standard, experts say — the same one that has gotten
EPA into legal messes in the past. Finalized last spring, EPA’s
current rule requires water utilities to remove the man-made
chemicals from drinking water starting in four years. Formally
called per-and polyfluoroalkyl substances or PFAS, “forever
chemicals” are known for their virtual indestructibility and
have been found in approximately half the nation’s tap water.
New polling shows Americans view ensuring a reliable water
supply as their top issue, beating out inflation, healthcare
reform and others. The polling comes from the US Water
Alliance’s Value of Water Campaign, an effort to raise
awareness of the need to support water infrastructure, and is
the first time a reliable water supply topped the list of key
issues. Reducing water contamination came in third, behind
inflation. Most Americans polled also expect the federal
government to make investments to improve and maintain water
infrastructure, the polling found, with the majority of
participants going as far as supporting bond measures and
higher local water bills to do so.
… How best to get rid of PFASs is now a multibillion-dollar
question. The EPA estimated that US utilities might have to
spend up to $1.5 billion annually for treatment systems; an
industry group that is suing the agency argues that costs could
be up to $48 billion over the next 5 years. Utilities must have
systems in place by 2029. … And although the EPA has
focused on drinking water, scientists want to stop PFASs from
ever reaching the water by removing them from other
environmental sources. … With looming deadlines,
academic researchers and companies are developing methods to
gather and destroy PFASs from these sources.
Fluoridated drinking water has been hailed as one of the top 10
public health achievements of the 20th century by the Centers
for Disease Control and Prevention (CDC). But it’s also a
practice that new health secretary Robert F. Kennedy, Jr. has
said should be halted. This week, Utah appeared to heed
his warnings, as Republican Gov. Spencer Cox signed legislation
late Thursday that banned fluoride in public drinking water
across the state, making it the first state to do so. “We
don’t need fluoride in our water. It’s a very bad way to
deliver it into our systems,” Kennedy had asserted the day
after the November election to NPR on Morning
Edition. Below, a primer on fluoride in drinking water,
its history of controversy, and what the science says.
Utah has become the first state to ban fluoride in public
drinking water, pushing past opposition from dentists and
national health organizations who warn the move will lead to
medical problems that disproportionately affect low-income
communities. Republican Gov. Spencer Cox signed legislation
Thursday barring cities and communities from deciding whether
to add the mineral to their water systems. Florida, Ohio and
South Carolina are considering similar measures, while in New
Hampshire, North Dakota and Tennessee, lawmakers have rejected
them. A bill in Kentucky to make fluoridation optional stalled
in the state Senate.
Drinking water has earned a “C-” on the 2025 American Society
of Civil Engineers (ASCE) Report Card for America’s
Infrastructure, which is the same score it received in 2021.
ASCE released the report card grading America’s infrastructure
on March 25, 2025, where the country received an overall grade
of “C,” its highest ever score. ASCE drinking water report card
The ASCE Report Card highlighted the need for funding and
building more resilient infrastructure. According to ASCE, the
U.S. Environmental Protection Agency (EPA) determined that the
nation’s water infrastructure needs stand at $625 billion over
20 years, exceeding EPA’s 2018 assessment by more than $150
billion. … The report highlighted new funding opportunities,
such as the Infrastructure Investment and Jobs Act (IIJA),
which invested more than $30 billion for drinking water
improvements, removal of lead service lines and addressing
emerging contaminants like per- and polyfluoroalkyl substances
(PFAS).
The EPA recently announced a consent decree with the operators
of the Oasis Mobile Home Park in California to resolve
violations of the Safe Drinking Water Act (SDWA). The consent
decree requires the park’s operators to upgrade its drinking
water and wastewater systems and pay a $50,000 penalty. … The
mobile home park is located within the Torres Martinez Desert
Cahuilla Indians Tribal Reservation boundaries in Thermal,
California, which is in the Eastern Coachella Valley. With an
estimated population of 1,000 people, it’s the valley’s largest
mobile home park, primarily serving agricultural workers,
according to the EPA. “While situated on Tribal land, the
public water and wastewater systems at Oasis operate
independently from Tribal control or ownership,” the EPA
release notes. “The Park’s drinking water system uses
groundwater that has high levels of naturally occurring
arsenic.”
Cities across California and the Southwest are significantly
increasing and diversifying their use of recycled wastewater as
traditional water supplies grow tighter.
The 5th edition of our Layperson’s Guide to Water Recycling
covers the latest trends and statistics on water reuse as a
strategic defense against prolonged drought and climate change.
Water bubbles up in streets, pooling in neighborhoods for weeks
or months. Homes burn to the ground if firefighters can’t draw
enough water from hydrants. Utility crews struggle to fix
broken pipes while water flows through shut-off valves that
don’t work. … Across the U.S., trillions of gallons of
drinking water are lost every year, especially from decrepit
systems in communities struggling with significant population
loss and industrial decline that leave behind poorer residents,
vacant neighborhoods and too-large water systems that are
difficult to maintain.
Water regulation in Arizona has devolved into a game of
chicken. The governor and farmers are rivals revving their
engines, hoping their opponent will flinch first. Caught
in the middle is Gila Bend, a groundwater basin south of
Buckeye, where the state could decide to impose its most
stringent form of regulation, whether folks like it or not.
Both sides are using Gila Bend as a bargaining chip to win
support for competing legislative proposals. But to what
end? - Written by Joanna Allhands, Arizona Republic digital
opinions editor
The U.S. Senate Indian Affairs Committee is holding an
important hearing Thursday on S. 2385, a bill to
refine the tools needed to help Tribal communities gain access
to something that most non-Indian communities in the western
United States have long taken for granted: federally subsidized
systems to deliver safe, clean drinking water to our homes.
… This is the sort of bill (there’s a companion on the
House side) that makes a huge amount of sense, but could easily
get sidetracked in the chaos of Congress. The ideal path is for
the crucial vetting to happen in a process such as Thursday’s
hearing, and then to attach it to one of those omnibus things
that Congress uses these days to get non-controversial stuff
done. Clean water for Native communities should pretty clearly
be non-controversial.
State health officials know that extreme heat can cost lives
and send people to the hospital, just like wildfire smoke. Now,
new research finds that when people are exposed to both hazards
simultaneously — as is increasingly the case in California —
heart and respiratory crises outpace the expected sum of
hospitalizations compared to when the conditions occur
separately. … The study joins a growing body of research
about the intersection of different climate risks. Last month,
California-based think-tank the Pacific
Institute published a report about how converging
hazards — including wildfires, drought, flooding, sea level
rise and intensifying storms — are harming access to drinking
water and sanitation in California and other parts of the
world. The deadly 2018 Camp fire in Butte
County impacted an estimated 2,438 private wells, the
report said.
After more than two decades of
drought, water utilities serving the largest urban regions in the
arid Southwest are embracing a drought-proof source of drinking
water long considered a supply of last resort: purified sewage.
Water supplies have tightened to the point that Phoenix and the
water supplier for 19 million Southern California residents are
racing to adopt an expensive technology called “direct potable
reuse” or “advanced purification” to reduce their reliance on
imported water from the dwindling Colorado River.
… A state audit from the California Water Resources Control
Board released last year found that over 920,000 residents
faced an increased risk of illness–including cancer, liver and
kidney problems–due to consuming unsafe drinking water. A
majority of these unsafe water systems are in the Central
Valley. The matter has prompted community leaders to mobilize
residents around water quality as politicians confront
imperfect solutions for the region’s supply. Advocates point
out that impacted areas, including those in Tulare County, tend
to be majority Latino with low median incomes. … This
year’s extreme weather has only worsened the valley’s problems.
The storms that hit California at the start of this year caused
stormwater tainted with farm industry fertilizer, manure and
nitrates to flow into valley aquifers.
Tiny pieces of plastic waste shed
from food wrappers, grocery bags, clothing, cigarette butts,
tires and paint are invading the environment and every facet of
daily life. Researchers know the plastic particles have even made
it into municipal water supplies, but very little data exists
about the scope of microplastic contamination in drinking
water.
After years of planning, California this year is embarking on a
first-of-its-kind data-gathering mission to illuminate how
prevalent microplastics are in the state’s largest drinking water
sources and help regulators determine whether they are a public
health threat.
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.”
Across a sprawling corner of southern Tulare County snug against the Sierra Nevada, a bounty of navel oranges, grapes, pistachios, hay and other crops sprout from the loam and clay of the San Joaquin Valley. Groundwater helps keep these orchards, vineyards and fields vibrant and supports a multibillion-dollar agricultural economy across the valley. But that bounty has come at a price. Overpumping of groundwater has depleted aquifers, dried up household wells and degraded ecosystems.
Shortly after taking office in 2019,
Gov. Gavin Newsom called on state agencies to deliver a Water
Resilience Portfolio to meet California’s urgent challenges —
unsafe drinking water, flood and drought risks from a changing
climate, severely depleted groundwater aquifers and native fish
populations threatened with extinction.
Within days, he appointed Nancy Vogel, a former journalist and
veteran water communicator, as director of the Governor’s Water
Portfolio Program to help shepherd the monumental task of
compiling all the information necessary for the portfolio. The
three state agencies tasked with preparing the document delivered
the draft Water Resilience Portfolio Jan. 3. The document, which
Vogel said will help guide policy and investment decisions
related to water resilience, is nearing the end of its comment
period, which goes through Friday, Feb. 7.
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.
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.
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.)
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.
More than a decade in the making, an
ambitious plan to deal with the vexing problem of salt and
nitrates in the soils that seep into key groundwater basins of
the Central Valley is moving toward implementation. But its
authors are not who you might expect.
An unusual collaboration of agricultural interests, cities, water
agencies and environmental justice advocates collaborated for
years to find common ground to address a set of problems that
have rendered family wells undrinkable and some soil virtually
unusable for farming.
Joaquin Esquivel learned that life is
what happens when you make plans. Esquivel, who holds the public
member slot at the State Water Resources Control Board in
Sacramento, had just closed purchase on a house in Washington
D.C. with his partner when he was tapped by Gov. Jerry Brown a
year ago to fill the Board vacancy.
Esquivel, 35, had spent a decade in Washington, first in several
capacities with then Sen. Barbara Boxer, D-Calif., and then as
assistant secretary for federal water policy at the California
Natural Resources Agency. As a member of the State Water Board,
he shares with four other members the difficult task of
ensuring balance to all the uses of California’s water.
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.
A statewide program that began under a 2015 law to help
low-income people with their water bills would cost about $600
million annually, a public policy expert told the California
State Water Resources Control Board (State Water Board) at a
meeting last week.
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.
Directly detecting harmful pathogens in water can be expensive,
unreliable and incredibly complicated. Fortunately, certain
organisms are known to consistently coexist with these harmful
microbes which are substantially easier to detect and culture:
coliform bacteria. These generally non-toxic organisms are
frequently used as “indicator
species,” or organisms whose presence demonstrates a
particular feature of its surrounding environment.

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:

stretching the water supply such as water marketing and
conjunctive use. New in this 10th edition of the guide is a
section on the human need for water.
The 24-page Layperson’s Guide to the Delta explores the competing
uses and demands on California’s Sacramento-San Joaquin Delta.
Included in the guide are sections on the history of the Delta,
its role in the state’s water system, and its many complex issues
with sections on water quality, levees, salinity and agricultural
drainage, fish and wildlife, and water distribution.
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

A tremendous amount of time and technology is expended to make
surface water safe to drink. Surface water undergoes many
processes before it reaches a consumer’s tap.
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.
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, 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
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 copy of Western Water examines the challenges facing
small water systems, including drought preparedness, limited
operating expenses and the hurdles of complying with costlier
regulations. Much of the article is based on presentations at the
November 2007 Small Systems Conference sponsored by the Water
Education Foundation and the California Department of Water
Resources.
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 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 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.
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.
