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.

A cartography of loss in the Borderlands

 …Local artists and curators…have taken on the task of remembering the [Mexicali] region’s departed waters. Since 2020, [they] have overseen the Archivo Familiar del Río Colorado, or Colorado River Family Album, a project that brings together contemporary art, environmental education and historical research to document bodies of water that are disappearing or are already gone …  In 2024, an exhibition at Planta Libre will collect archival documents and artwork that engages with water and its loss. Local artists will lead a series of walks in the surrounding region so that visitors can develop their own relationship with it … the absence of the Colorado River and the waters it nourished forms a cartography of loss that is written on the landscape. Their mission is to make those absences visible — to keep their memories alive, and to imagine possibilities for the future.

Fish loss, sediment flows were expected after dam removal, Klamath River Renewal Corporation leaders say

The massive deaths of non-native fish and the deluge of sediments resulting from the drawdown of reservoirs as part of the Klamath River dam removals was expected and is predicted to result in long-range benefits.  Public concern has been expressed following because of the recently completed initial drawdown of reservoirs created by the John C. Boyle, Copco 1 and Irongate hydroelectric dams. Copco 2, a diversion dam, was removed late last year because it would have interfered with the Copco 1 drawdown. The dam removal project is the largest in U.S. history. During a Thursday video news conference, Mark Bransom, chief executive office for Klamath River Renewal Corporation, which is overseeing the dam removal project, and Dave Coffman, the habitat restoration as program manager for RES (Resource Environmental Solutions), briefly discussed the ongoing project and impacts of the recently completed initial drawdown.

Atmospheric rivers in California create a perfect storm of public health risks

After a torrential downpour, most post-storm damages are impossible to miss: submerged cars, houses torn in half by fallen trees, debris floating through the streets. But in California, extreme weather is also mixing up a soup of rain and disease. Climate-fueled outbreaks: In Southern California, an atmospheric river unleashed more than a foot of rain in parts of the region at the start of February. These types of storms also ravaged the state last year, following a decades-long period of drought. The climate-fueled cycle of rain and drought is driving an uptick in a fungal disease known as coccidioidomycosis, or Valley fever …

Water quality discussed after completion of Klamath reservoir drawdown

Iron Gate, the lowest of the Klamath dams, was breached first on Jan. 9, followed by J.C. Boyle in Oregon, and finally, Copco 1. Draining the three reservoirs marks another milestone toward the removal of dams in the Lower Klamath Project. … In total, KRRC expects 5 to 7 million cubic yards of sediment — the same amount that the Klamath River would normally drain in a single year — to wash downstream over a short period of time. The material, composed mostly of very fine silt and dead algae, has imbued the river with a dark coffee color. For several days last week, dissolved oxygen levels in the first 20 miles below Iron Gate dam hovered close to zero. Decomposing algae rob water of oxygen, as do oxidizing minerals. As the last of the reservoirs drained, they released oxygen-poor water, as well.

Managing a cyanobacteria harmful algae bloom “hotspot” in the upper San Francisco estuary

At the January meeting of the Delta Stewardship Council, interim Delta Lead Scientist Dr. Lisamarie Windham-Myers highlighted recent research on Harmful Algal Blooms, and highlighted upcoming Delta science events. This month’s article spotlight focuses on research funded by the Delta Science Program on the harmful algal blooms in 2022, a uniquely bad year for the toxic menace.  The research, led by Ellen Preece, focused on how nutrient loading affected cyanobacteria harmful algae blooms (CHABs) in the Deep Water Ship Channel and the Stockton waterfront area in the summer of 2022 and considered four categories of management actions to mitigate the occurrence and impact of the blooms.

Brawley’s Wiest Lake algae issue gets some help 

In a move that Imperial County Public Works officials hope will set to rest an issue at Brawley’s Wiest Lake that has been ongoing since last summer and beyond, an algae-control system will now be installed as a preventative measure to halt the harmful algae blooms that intermittently closed the lake and threatened native ecosystems in the area.  The Imperial County Board of Supervisors unanimously approved the purchase and installation of the system at the meeting on Tuesday, Feb. 6, by recommendation of Public Works Director John Gay. The proposed LG Sonic device is a “floating, solar-powered platform” that, according to the algae-control professionals, should “reduce algal blooms by up to 70-90%.” “It’s an ultrasonic system that is solar-powered, and it delivers sounds that we cannot hear,” Assistant Public Works Director David Dale summarized for the county board.

New study: Consumption of teas, takeout, hot dogs could come with a side of ‘forever chemicals’

Young adults whose diets are rich in unsweetened teas, processed meats and takeout foods could be increasing their exposure to “forever chemicals,” a new study has found. Altering these eating habits could bring notable declines in the levels of these compounds, known as PFAS, that are contaminating their blood, according to the study, published Monday in Environment International. … Known for their ability to linger in the environment and the human body, PFAS (per- and polyfluoroalkyl substances) have been linked to kidney cancer, thyroid disease and other illnesses. While most notorious for their presence in certain types of firefighting foams and industrial discharge, PFAS are also present in many household and commercial products, such as nonstick pans and food packaging, as well as contaminated livestock and drinking water.

Blog: New report highlights how climate change is worsening water and sanitation access for frontline communities in the united states

In a newly released report, the Pacific Institute and DigDeep, in partnership with the Center for Water Security and Cooperation, paint a sobering picture of how climate change is straining access to water and sanitation in communities throughout the United States. The new research details how frontline communities, those hit “first and worst” by climate change, face disproportionate impacts in the United States when trying to access basic water and sanitation systems. The report, entitled “Climate Change Impacts to Water and Sanitation for Frontline Communities in the United States,” is the first in the new multi-report series: “Water, Sanitation, and Climate Change in the United States.” For the millions of people in the United States who currently lack basic indoor plumbing or have unsafe water, climate change will continue to exacerbate their ability to access water and sanitation.

The best countertop water filters and pitchers for reducing nanoplastics and forever chemicals

Water quality (or the lack thereof) has been making headlines a lot lately. A study just released in January 2024 found significantly higher levels of nanoplastics than expected in bottled water. Another recent (July 2023) study found PFAS (aka “forever chemicals”) in many public drinking water systems nationwide.  So it’s understandable if you’re feeling worried and confused about how to find safe, clean drinking water. There are plenty of water filtration products available, but not all of them are fully transparent about which contaminants they can remove from water. Things get even trickier with microplastics and PFAS. Since research into these substances is relatively new, only a handful of water filters have been tested for their ability to remove them. To help you cut through all the misleading and confusing marketing claims around water filters, we’ve rounded up products that have gone through independent, third-party testing to verify that they can, in fact, remove microplastics and forever chemicals.

Raw sewage in creeks? Sunnyvale and Mountain View argue in court the Clean Water Act should not apply to them

When it comes to the environment, Sunnyvale and Mountain View have a pretty green image, spending millions on bike lanes, solar energy and electric vehicle charging stations. But their tactics in an ongoing court case — in which their lawyers claimed major Bay Area creeks should not be protected from pollution under the federal Clean Water Act — are raising eyebrows among environmentalists. … The Clean Water Act is one of America’s landmark environmental laws. Passed by Congress in 1972, it prohibits the discharge of pollutants like chemicals, sewage, garbage and toxic waste into creeks, rivers, lakes and bays without a federal permit. In 2020, Baykeeper sued Sunnyvale and Mountain View, saying they have been violating the Clean Water Act for years by discharging raw sewage and polluted stormwater into creeks, sending bacteria pollution to levels more than 50 times legal limits.

Dairies in Tulare and Kings counties still struggling with damage in wake of last year’s flooding

When flood water swamped dairies in Tulare and Kings counties last spring, it destroyed equipment, drowned crops and left a trail of salt-laden muck that farmers are still grappling with.  The ongoing damage is so bad, some dairies may never recover. The biggest problem is the loss of crops and cropland. Farmers lost an entire year’s worth of wheat, used for feed, that was submerged as the Tule River and other creeks swelled and water gushed over thousands of acres. That lost crops and cropland, led to a chain of other problems, said Anja Raudabaugh, CEO of Western United Dairies. The price of wheat skyrocketed, but one of the bigger challenges was where to put all the cow manure.

Editorial: Nanoplastics are dangerous — and in bottled water

Is anyone really surprised to learn that bottled drinking water is loaded with tiny bits of plastic? The bottles are, after all, plastic. So are the caps. It stands to reason that microscopic bits of the stuff get into the water inside during bottling or packaging, or while sitting in storage. A 2018 study found as much. The shocking part of a recent Columbia University Lamont-Doherty laboratory study, published last week in the journal Proceedings of the National Academy of Sciences, is the revelation that bottled water is laden with even tinier nanoplastic bits and associated chemicals. … [C]ompanies selling water in standard-sized 16.9-ounce plastic bottles are marketing geniuses. Many of them source their liquid assets from the same streams and springs that feed municipal taps, and then sell it back to consumers — implying that it’s purer and safer than the very same stuff that flows into the sink. … Some get their water from deep wells or melting glaciers that existed before humanity — and then add dangerous microplastics by bottling it.

A new study finds a critical vitamin for salmon in rivers

Thiamine, also known as vitamin B1, is critical for salmon health. Juvenile fish can die without enough of the nutrient. Researchers have known salmon’s ocean diet impacts their thiamine levels. Scientists at Oregon State University have called “thiamine deficiency complex” a growing threat. For example, a diet rich in anchovies rather than sardines can lead to a deficiency. But for the first time, scientists have measured the vitamin’s availability in freshwater rivers where the fish deposit eggs.

In late October, Canada geese were found dead in Sacramento County and submitted to the California Department of Fish and Wildlife’s (CDFW) Wildlife Health Laboratory for testing. Preliminary testing was performed at the California Animal Health and Food Safety Laboratory in Davis. The U.S. Department of Agriculture’s (USDA) National Veterinary Services Laboratories confirmed the detection of HPAI H5N1 in two Canada geese in early November. Subsequent detections have been made in wild birds in several additional counties during mortality surveillance including from Contra Costa, San Diego, Santa Clara, Solano and Yolo. Detections in waterfowl during hunter-harvest surveillance have been reported from Fresno, Glenn, Kern and Yolo counties. Prior to these detections, the last confirmed detection in wild birds occurred in June 2023.

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.

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.

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.

Headwaters Tour 2019
Field Trip - June 27-28

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.

Lower Colorado River Tour 2019

This three-day, two-night tour 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 is the focus of this tour.

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.

Algal Blooms

Algal blooms are sudden overgrowths of algae. Their occurrence is increasing in California’s rivers, creeks and lakes and along the coast, threatening the lives of people, pets and fisheries.

Only a few types of algae can produce poisons, but even nontoxic blooms hurt the environment and local economies. When masses of algae die, the decaying can deplete oxygen in the water to the point of causing devastating fish kills.

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.

Two Sides of a River (60-minute DVD)

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.

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

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.

Aquapedia background Layperson's Guide to California Wastewater

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.

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.
