Topic: Water Quality

Overview

Water Quality

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.

Field Trip - March 16-18

The lower Colorado River has virtually every drop 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, 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 was the focus of this tour.

Is Ecosystem Change in the Sacramento-San Joaquin Delta Outpacing the Ability of Science to Keep Up?
WESTERN WATER IN-DEPTH: Science panel argues for a new approach to make research nimbler and more forward-looking to improve management in the ailing Delta

Floating vegetation such as water hyacinth has expanded in the Delta in recent years, choking waterways like the one in the bottom of this photo.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.

Long Criticized For Inaction At Salton Sea, California Says It’s All-In On Effort To Preserve State’s Largest Lake
WESTERN WATER NOTEBOOK: Dust suppression, habitat are key elements in long-term plan to aid sea, whose ills have been a sore point in Colorado River management

The Salton Sea is a major nesting, wintering and stopover site for about 400 bird species. 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.

As Wildfires Grow More Intense, California Water Managers Are Learning To Rewrite Their Emergency Playbook
WESTERN WATER IN-DEPTH: Agencies share lessons learned as they recover from fires that destroyed facilities, contaminated supplies and devastated their customers

Debris from the Camp Fire that swept through the Sierra foothills town of Paradise  in November 2018.

By Gary Pitzer and Douglas E. Beeman

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.

How Private Capital is Speeding up Sierra Nevada Forest Restoration in a Way that Benefits Water
WESTERN WATER SPOTLIGHT: A bond fund that fronts the money is expediting a headwaters restoration project to improve forest health, water quality and supply

District Ranger Lon Henderson with Tahoe National Forest points toward an overgrown section of forest within the Blue Forest project area. 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.

Can Providing Bathrooms to Homeless Protect California’s Water Quality?
WESTERN WATER IN-DEPTH: The connection between homelessness and water is gaining attention under California human right to water law and water quality concerns

A homeless camp set up along the Sacramento River near downtown Sacramento. 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.

Amid ‘Green Rush’ of Legal Cannabis, California Strives to Control Adverse Effects on Water
WESTERN WATER IN-DEPTH: State crafts water right and new rules unique to marijuana farms, but will growers accustomed to the shadows comply?

A marijuana plant from a growing operationFor 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.

EDITOR’S NOTE: Assessing California’s Response to Marijuana’s Impacts on Water

Jennifer BowlesAs 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.

Runoff

Snowmelt and runoff near the California Department of Water Resources snow survey site in the Sierra Nevada east of Sacramento.Runoff is the water that is pulled by gravity across land’s surface, replenishing groundwater and surface water as it percolates into an aquifer or moves into a river, stream or watershed.

Aquapedia background

Algal Blooms

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

Photo of drinking water filling a glass over the kitchen sink. 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 Source vs. Nonpoint Source Pollution

Point Source Pollution

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.

Salton Sea

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.

The most recent version of the Salton Sea was formed in 1905 when the Colorado River broke through a series of dikes and flooded the seabed for two years, creating California’s largest inland body of water. The Salton Sea, which is saltier than the Pacific Ocean, includes 130 miles of shoreline and is larger than Lake Tahoe

Water Treatment

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.]

Water Quality

A water treatment plant

People, farmers, industry and the environment in California depend on clean water to survive.

Surface waters, however, are threatened by a host of pollutants, such as bacteria, trash and agricultural runoff. Groundwater in California also can be contaminated by nitrates and industrial chemicals that seep from the land above. [See also How is Drinking Water Treated?]

Wastewater Treatment Process in California

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.

Regional Water Quality Control Boards in California

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.

Safe Drinking Water Act

Safe Drinking Water Act

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 Gold Rush and Today’s Water

More than 100 years ago, California’s Gold Rush left a toxic legacy that continues to cause problems in Northern California watersheds.

The discovery of gold in John Sutter’s millrace at Coloma in the 1840s drew people from around the globe.

Over the course of decades, intense efforts were focused on washing and prying gold from the hills of the Sierra Nevada.

Nitrate and the Struggle for Clean Drinking Water
March/April 2013

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.

Unlocking the Mysteries of Selenium
Mar/Apr 2006

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.

Jul/Aug 2004

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.

Confronting a Legacy of Contamination: Perchlorate
May/Jun 2003

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.

TMDLs: A Tool for Better Water Quality?
May/Jun 2001

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 Challenges: A Roundtable Discussion
Jan/Feb 2001

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.

The Challenge of MTBE: Clean Air vs. Clean Water?
Jul/Aug 1998

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.
