Balancing protein in your diet could improve water quality

Kat Kerlin, UC DAVIS NEWS

Eating Too Much Protein Adds to Nitrogen Pollution in U.S. Waters

…when a body takes in more protein than it needs, excess amino acids break it down into nitrogen, which is excreted mostly through urine and released through the wastewater system. This brings additional nitrogen into waterways, which can result in toxic algal blooms, oxygen-starved “dead zones” and polluted drinking water.

Balancing how much protein you eat with the amount your body needs could reduce nitrogen releases to aquatic systems in the U.S. by 12% and overall nitrogen losses to air and water by 4%, according to a study from the University of California, Davis.

Protein consumption in the United States, from both plant and animal sources, ranks among the highest in the world. The study, published in the journal Frontiers in Ecology and the Environment, said that if Americans ate protein at recommended amounts, projected nitrogen excretion rates in 2055 would be 27% less than they are today despite population growth.

The study is the first to estimate how much protein consumption contributes to excess nitrogen in the environment through human waste. It also indicates that coastal cities have the largest potential to reduce nitrogen excretions headed for their watersheds.

“It turns out that many of us don’t need as much protein as we eat, and that has repercussions for our health and aquatic ecosystems,” said lead author Maya Almaraz, a research affiliate with the UC Davis Institute of the Environment. “If we could reduce that to an amount appropriate to our health, we could better protect our environmental resources.”

Friends of Gualala River launch new lawsuit targeting logging on North Fork

Chris McManus, INDEPENDENT COAST OBSERVER

As part of its Salmonid and Watershed Restoration Project, Friends of Gualala River has launched a new lawsuit, this one focused on the Gualala River’s North Fork in the watershed’s northwest corner, the only hydrologic area of the watershed that is not temperature impaired.

The suit was filed last Wednesday in Alameda Superior Court against the California Regional Water Quality Control Board, the State Water Resources Control Board and Gualala Redwood Timber, LLC, seeking to stop Gualala Redwood Timber’s “Far North” timber harvest plan, No. 1-20-00150 MEN.

The new suit comes as FoGR is continuing to fight Gualala Redwood Timber’s “Dogwood III” THP. Judge James Donato on Tuesday issued a 14-day temporary restraining order on that timber harvest plan while he continues to consider a longer restraining order in the federal case brought by FoGR and the Center for Biological Diversity.

The newest lawsuit against the water boards is part of systemic reform FoGR is seeking to hold state agencies involved in the review of timber harvest plans accountable for their roles in the process. Previous lawsuits have targeted CalFire, the final reviewer and approver of timber harvest plans in California.

Petaluma River cleanup plan approved

Will Carruthers, NORTH BAY BOHEMIAN

On May 10, the Environmental Protection Agency (EPA) quietly signed off on a plan meant to reduce pollution in the 146-square-mile Petaluma River Watershed.

That’s right. Although the problem is rarely discussed, the Petaluma River has been listed as “impaired” by excessive levels of bacteria since 1975.

The bureaucratic document approved by the EPA is known as a Total Maximum Daily Load (TMDL). It sets levels of acceptable waste discharge from various sources in an attempt to lower the levels of fecal bacteria found in the watershed until the water is deemed clean.

While preparing the TMDL, scientists from the San Francisco Bay Regional Water Quality Control Board tested water from throughout the watershed for Fecal Indicator Bacteria to determine the amount of waste from warm-blooded mammals that has seeped into the water. Although indicator bacteria themselves are not dangerous, scientists use the strains to detect potentially dangerous levels of contamination in the water.

In a report accompanying the TMDL, water board staff identified 12 sources of pollution, which they then lumped into three general categories: human waste, animal waste and municipal stormwater runoff. In tests conducted between 2015 and 2016, water board scientists found bacteria tied to humans, horses, cows and dogs throughout the Petaluma River and its tributaries.

When asked in late 2019 about the levels of E. coli discovered in the Petaluma River, Farhad Ghodrati, an environmental scientist with the San Francisco Bay board, said the test results showed “some of the highest concentrations we have seen in the region.”

At the same time, Dr. Celeste Philips, who then served as Sonoma County’s Health Officer, warned Petaluma River users against drinking the river water or using the water for cooking due to the levels of E. coli. “Adults and children should wash hands/shower and towel dry after swimming; rinse off pets after they come into contact with the water,” Philips added.

Point Reyes dairies targeted over water quality concerns

Tyler Silvy, PETALUMA ARGUS-COURIER

A regional water quality board has launched an investigation into the management practices of three Point Reyes dairies after testing sponsored by environmental advocates uncovered polluted waterways near the more than century-old operations.

The Kehoe Dairy, McClure Dairy and M&J McClelland Dairy have been targeted for on-site inspections by the San Francisco Bay Regional Water Quality Control Board, officials confirmed this week, a move that could lead to greater monitoring.

The dairies, located in the northern half of the 70,000-acre Point Reyes National Seashore, each drain to the Pacific Ocean, either via Kehoe Beach to the north or Abbotts Lagoon – popular destinations for hikers and beachgoers.

Water samples collected in late January at multiple locations near the dairies showed elevated levels of bacteria, including coliform bacteria, a key indicator for the presence of fecal matter, according to a civil engineer’s report that was later reviewed by the water quality agency.

“Apocalypse Cow:” Point Reyes National Seashore launches a propaganda war targeting independent journalism

Erik Molvar, COUNTERPUNCH

Grab your popcorn: The battle over livestock destruction of natural ecosystems at Point Reyes National Seashore is heating up. For years, conservationists have pointed out the ecologically catastrophic toll that beef and dairy ranching has been having on native coastal prairies, the wildlife that depend on these places, and public health and safety. As the news media has caught on, the tide of public opinion has turned against the livestock producers, in favor of protecting the very rare tule elk population and shifting management of the National Seashore away from livestock production toward public recreation and enjoyment. Now, a National Park Service unit is launching a propaganda war in a desperate effort to control the media narrative, and to cover up decades of laissez-faire mismanagement of livestock operations leasing Park Service lands on the National Seashore.

The flap centers around an investigative journalism piece titled “Apocalypse Cow: The Future of Life at Point Reyes National Park,” which ran in The Bohemian and the Pacific Sun, two local weekly newspapers that serve the counties surrounding Point Reyes National Seashore, and subsequently in Counterpunch. The article characterizes the Park Service analysis of environmental effects of cattle ranching on Point Reyes as “deeply flawed scientifically, culturally and ethically” and “politicized.” It’s a long and in-depth article, covering the politics of Point Reyes, and highlighting the ecologically harmful confinement of elk behind a massive fence on sometimes-waterless Tomales Point, the negative impact that cattle operations are having on climate change, commercial ranching’s destructive influence on rare and protected species of fish and wildlife, water contamination by livestock manure, and the contrast between coastal Miwok stewardship of Point Reyes’ native ecosystems and today’s destruction of those ecosystems at the hands of commercial ranching. Based on responses to the article, the locals seem to appreciate the insightful reporting.

The Park Service is doing its utmost to discredit the piece. On its webpage, “Frequently Asked Questions about the General Management Plan,” the Park Service has a section called “Corrections regarding misinformation published in the press.” The Park Service alleges errors; The Bohemian checked the verity of the article and stands behind it as factual reporting.

California to impose first statewide rules for winery wastewater, marking new era

Tyler Silvy, THE PRESS DEMOCRAT

Hundreds of California wineries will for the first time be governed by statewide wastewater processing rules, a change from the long-held, regional approach that could increase production costs for wineries and protections for waterways while providing consistency for vintners across the state.

The move toward a statewide regulatory framework, a five-year effort championed by industry leaders, was finalized this week by the State Water Resources Control Board, which approved an order setting up guidelines for wastewater processing at most of the more than 3,600 bonded wineries in the state.

The new order promises to bring at least 1,500 of those wineries into a regulatory framework for wastewater disposal for the first time, leading to extra compliance costs. But it also provides flexibility for how, and when, those wineries will be subject to rules meant to safeguard waterways and groundwater from harmful contaminants, including excess nitrogen, salinity and other compounds that deplete oxygen levels.

“I think it was the perfect example of a compromise,” said Don McEnhill, head of the Sonoma County-based group Russian Riverkeeper.

Apocalypse cow: The future of life at Point Reyes National Park

Peter Byrne, THE BOHEMIAN

The North Bay community is divided by conflicted views on whether commercial dairy and cattle ranching should continue at Point Reyes National Seashore. This reporter has hiked the varied terrains of the 71,000-acre park for decades. Initially, I had no opinion on the ranching issue. Then, I studied historical and eco-biologic books and science journals. I read government records, including the Environmental Impact Statement (EIS) on Point Reyes released by the National Park Service in September. The 250-page report concludes that the ranching industry covering one third of the park should be expanded and protected for economic and cultural reasons. This, despite acknowledging that the park ranches are sources of climate-heating greenhouse gases, water pollution, species extinctions and soil degradation.

The Bohemian/Pacific Sun investigation reveals that the EIS is deeply flawed scientifically, culturally and ethically. It is politicized.

Sixty million years ago a chunk of granite located near Los Angeles began moving northwards. Propelled by the energy of earthquakes over eons, Point Reyes slid hundreds of miles along the San Andreas fault at the divide between two colliding tectonic plates.

During the last Ice Age, 30,000 years ago, much of the Earth’s waters were locked up in glaciers, and the Pacific Ocean was 400 feet lower than it is today. “The Farallon Islands were then rugged hills rising above a broad, gently sloping plain with a rocky coastline lying to the west,” according to California Prehistory—Colonization, Culture, and Complexity.

Humans migrated from Asia walking the coastal plains toward Tierra del Fuego. Then, 12,000 years ago, the climate warmed and glaciers melted. Seas rose, submerging the plains. A wave of immigrants flowed south from Asia over thawed land bridges. Their subsequent generations explored and civilized the Americas, coalescing into nations, including in West Marin and Point Reyes.

Novelist and scholar Greg Sarris is the tribal chair of the Federated Indians of the Graton Rancheria. The tribe’s ancestors are known as Southern Poma and Coast Miwok. In The Once and Future Forest, Sarris tells the story of how the first people came to be in Marin and Sonoma counties. “Coyote created the world from the top of Sonoma Mountain with the assistance of his nephew, Chicken Hawk. At that time, all of the animals and birds and plants and trees were people. … The landscape was our sacred text and we listened to what it told us. Everywhere you looked there were stories. … Everything, even a mere pebble, was thought to have power … Cutting down a tree was a violent act. … An elder prophesied that one day white people would come to us to ‘learn our ways in order to save the earth and all living things. … You young people must not forget the things us old ones is telling you.’”

Cazadero cannabis grower pleads guilty to felony environmental violations

Zoe Strickland, SONOMA WEST TIMES & NEWS

Michael Silva, 37, of Cazadero pled guilty to three felony counts related to environmental violations on a property where he was growing 1,450 cannabis plants, the Sonoma County District Attorney’s Office announced Thursday night, Oct. 29.

Silva hadn’t obtained environmental permits for his grow. According to the district attorney’s office, he will perform remediation, 300 hours of community service, obtain the correct permits and satisfy other requirements related to cultivating on the Cazadero property “with the understanding that charges will be dismissed upon completion in a year.”

The cannabis operation was discovered in September 2019 by the California Department of Fish and Wildlife (CDFW). Upon the discovery and following the execution of a warrant, it was determined that Silva was diverting water without permits and engaging in unpermitted construction work without best management practices that could resort in water pollution.

District Attorney Ravitch stated, “The defendant’s activities not only presented unacceptable harm to the environment but also contributed to the illegal cannabis market, a problem for this community and for lawful cultivation.”

“Silva will not be sentenced provided he abides by his agreement with the prosecution,” the statement from the district attorney’s office states. “The agreement also requires Silva to obtain the necessary permits to perform stream restoration over the next year. Should Silva fail to comply with the agreement reached with the prosecution, he faces potential administrative enforcement by sister state agencies, including CDFW and the Water Boards, and is subject to a maximum sentence of 10 years.”

The case was prosecuted by Deputy District Attorney Ann Gallagher White, with investigation provided by CDFW and with assistance from the Water Boards.

‘Ozone friendly’ chemicals are polluting the environment

Jordan Davidson, ECOWATCH

The Montreal Protocol of 1987 committed nations around the world to stop using the chlorofluorocarbons (CFC) that created a hole in the ozone layer. While it stands as one of the most effective environmental commitments the globe has seen, new research shows the side effects have been costly as chemicals dangerous to human health build up in the environment, as the BBC reported.

New research published in the journal Geographical Research Letters analyzed Arctic ice and found an unintended consequence of the Montreal Protocol. The compounds that replaced CFCs have been transported and transformed in the atmosphere, depositing far from their sources. The new generation of chemicals that replaced Freon, but are used in refrigerators, air conditioners and new cars have been accumulating since 1990.

“Our results suggest that global regulation and replacement of other environmentally harmful chemicals contributed to the increase of these compounds in the Arctic, illustrating that regulations can have important unanticipated consequences,” said Cora Young, a professor at York University in Canada, and an author of the paper, in a York University statement.

Scientists first discovered ozone depletion in the 1970s when they detailed the deterioration of the stratospheric ozone layer around the earth’s poles. As the hole over Antarctica opened and expanded, scientists found that the depletion of ozone was responsible for a greater intensity of ultraviolet radiation from the sun, causing an increase in the prevalence of skin cancer, eye cataract disease and other harmful effects on humans, as Courthouse News reported.

Scientists were soon able to pinpoint manufactured chemicals used in air conditioners and refrigerators, as well as solvents, propellants and chemical agents found in foam as the cause of the depleted ozone layer.

Now pollution from the chemicals that were created to replace the CFCs, known as short chain perfluoroalkyl carboxylic acids (scPFCAs), has proliferated around the world. The replacement chemicals are a class of PFAS, or forever chemicals, that have polluted waterways and made groundwater in certain areas toxic to drink.

Too little (but not too late) for the Petaluma River

San Francisco Baykeeper Update

Updated: On March 17, 2020, Baykeeper further challenged the Regional Board’s flawed plan before the oversight agency, urging the State Water Board to reject the plan as inadequate. Baykeeper’s scientists maintain that the Petaluma River is currently so contaminated with bacteria that people will get sick swimming and paddling in the waters, and our lawyers contend that the plan fails to hold accountable all of the sewage polluters along the River.

In 1975, scientists found that the Petaluma River was so heavily contaminated with E. Coli and other bacteria that it was unsafe to have any contact with the water. The presumed sources of the bacteria included animal and human waste running off of ranches, stables, farmland, and out of broken waste water treatment and septic systems.

Today, little has changed. The Petaluma River remains dangerously contaminated, with high levels of bacteria showing up in every single water test taken in the river.

Despite the findings nearly 45 years ago, the agency responsible for protecting the watershed—the San Francisco Bay Regional Water Quality Control Board—waited until 2019 to address the Petaluma’s troubling bacteria levels.

And unfortunately, the Water Board’s new plan doesn’t take the right steps to reduce bacteria pollution in the Petaluma. The Clean Water Act mandates that agencies start by identifying the specific sources under a regulatory strategy known as a Total Maximum Daily Load (TMDL).

Though the Water Board is calling their new policy a TMDL, it doesn’t establish where the bacteria pollution is coming from, by how much the bacteria sources must be reduced, or how progress will be monitored and enforced.

“It’s misleading for the Water Board to call this a TMDL, and their approach is doomed to take decades to solve the problem,” says Baykeeper Staff Attorney Ben Eichenberg. “While Baykeeper appreciates the Board’s stated goal of making water quality in the Petaluma River better, the agency is failing its actual obligation to make the river truly safe for people.”

The Petaluma River feeds into creeks across the North Bay and Marin, and eventually connects with San Francisco Bay. It attracts boaters, paddle boarders, kayakers, and anglers.

If cleaned up, this beautiful waterway could become a world-class destination for water sports enthusiasts and shoreline activities of all kinds, while contributing to a healthier San Francisco Bay.

As the Petaluma River TMDL heads to the EPA for a final review, Baykeeper will continue to push for a smarter approach. We can’t let another 45 years go by before it’s safe to swim in the Petaluma.
