Sharing Science Across Barriers

Growing up on Chicago’s South Side, an urban landscape of metal and concrete, Miguel Mendez had limited access to open spaces, and always dreamed of traveling. Yet there in the city, he got his first introduction to environmentalism. “In some of the places I lived in Chicago, environmental activists are fighting air pollution and the limitation on parks,” Mendez says. Many of those groups have been there for years, and as he grew up, Mendez internalized the importance of preserving and advocating for a safe environment for all communities. When he was about to enter ninth grade, Mendez applied for a scholarship to an environmentally focused high school. So instead of walking into a classroom his freshman year, he found...

Drought Strains Stormwater Monitoring Endeavors

When it rains, it pours. This old saw passes for an apt description of the new precipitation regime that climate change has wrought for the Bay Area: larger winter storms, but fewer of them. The implications of this shift for ecosystems, infrastucture, and water storage are widespread, and often highly visible. But behind the scenes, it is also complicating efforts to monitor pollution inputs to the San Francisco Bay and other local water bodies from stormwater runoff. The Regional Monitoring Program for Water Quality in San Francisco Bay (RMP) has been collecting data in Bay water, sediment, and biota since 1993. RMP monitoring of stormwater flows after rain events, which began in 2006, has shown that runoff is a major...

Bagman for Bay Mussels

Martin Trinh practically bounces along the dock at the Coyote Point Yacht Club on a breezy, sunny spring morning. He’s carrying a case full of instruments and scopes out an open slip at the end of the pier. Soon he’s lowering a probe into the water, alongside kelp clinging to the underside of the dock. Another trip back to his Prius, still sporting South Carolina license plates, and he’s got a white plastic dish pan and a scrub brush. He fills and rinses a brown plastic bottle several times before finally capping it while full and placing it into a zip-top plastic bag. Then he lies on his belly, reaches into the water, and with blue nitrile gloves feels amidst...

West Coast Salmonids All Tired Out?

West Coast salmon and steelhead populations have declined steeply in the past century – a plight that biologists have primarily blamed on habitat loss. Dams, for instance, block adult fish’s access to historic spawning grounds, and juvenile survival is impacted by streamside development and water diversions. Now, it turns out, microplastic pollution may be a much bigger factor than anyone knew just several years ago. In 2019, scientists with the San Francisco Estuary Institute and the Los Angeles-based nonprofit 5 Gyres published findings indicating that car tire particles are one of the most prevalent forms of microplastic pollution flowing into San Francisco Bay. Then, in 2020, a team of West Coast scientists discovered that a chemical in these particles is...

Tracking Natural Nitrogen Removal

Nitrogen inputs to the San Francisco Bay are among the highest of estuaries worldwide, yet so far have not caused harmful impacts like extreme algal blooms, oxygen depletion, and fish kills. But resistance to this nutrient may not last. Ever since the Gold Rush, excess sediment from pulverized rock has been pouring into the Bay, clouding the water and keeping algae in check by blocking sunlight. Recently, however, that protective sediment has diminished in parts of the Bay, contributing to concerns over nutrient pollution. A new study on a natural nitrogen-removal process is key to predicting whether nitrogen will cause ill effects here, too. The Bay’s nitrogen comes primarily from sewage and, for the most part, this nutrient is not...

Bay Fish Still Not Good Eating

After decades of efforts to clean up San Francisco Bay, its fish still carry a toxic load that makes them unfit for human consumption. A new Regional Monitoring Program (RMP) report on its 2019 sport fish survey contains some positive news: an overall decline in polybrominated diphenyl ethers (PBDE), hopeful trends in polychlorinated biphenyls (PCBs) and dioxin, and continued low selenium levels. But no downward trend was found for mercury. Then there are per- and polyfluoroalkyl substances (PFAS), which the RMP only began monitoring in 2009 and for which no human consumption advisory levels have been established in California. These chemicals, used in stainproofing, waterproofing, and many other applications, are a new cause for concern. The 2019 survey was the...

Sediment Paparazzi

As the Estuary faces drowning marshes due to rising seas, people want to see action – acres saved, walls built, marsh mice whisked to safety after crawling to the tip of the tallest gumplant. In terms of action, “sediment monitoring” doesn’t come immediately to mind. Monitoring is something you do after all the action is over, isn’t it? And as for “sediment,” well what’s all the fuss over some dirt and mud? In fact, there is quite a fuss. The Bay region has a sediment management strategy and a sediment monitoring and modeling strategy, and later this month it will have a new sediment supply and demand analysis. Indeed, six different workgroups of Bay scientists, managers, and regulators are now...

Virtual RMP Annual Meeting Real-Life Success

Instead of a fancy room with plush seats, a catered lunch, and speakers at a podium sharing their presentations on a big screen, attendees at the 27th Annual Meeting of the Regional Monitoring Program for Water Quality in San Francisco Bay (RMP) experienced the report-out entirely virtually on their own computer screens, thanks to the Covid pandemic. Nevertheless, and despite Zoom burnout, the October event was a success, with many attendees voicing a preference for the virtual format. Hot science take homes from the presentations were plentiful. Several sessions covering both Atlantic and Pacific Coasts explored how scientists continue to focus on sediment movement through watersheds and estuaries, especially with its long-standing transport of hitch-hiking contaminants. In the Bay Area,...

A Fragile Fleet

Watching Bay-Delta science unfold, we take for granted the little armada that keeps it all going. Nobody has a firm count, but it appears there are about 100 vessels supporting research in the Estuary. They range from a few large craft that can work outside the Golden Gate to little “trailerable” skiffs and Adirondack rowboats that ply Delta shallows. Like many of the systems that quietly sustain our society, this one is showing signs of strain.

Match Points in Stormwater Soup

Effluent from wastewater treatment plants is often seen as the primary source of emerging contaminants in San Francisco Bay. But a report published in July by the Regional Monitoring Program challenges that assumption by highlighting the importance of urban stormwater runoff as another major source.

Microtrash Tiresome for Watersheds

As many as 30 particles of microplastic smaller than five millimeters in diameter are discharged with every liter of stormwater, according to a report published by the San Francisco Estuary Institute and 5Gyres last October. “A big proportion of what we saw were black rubbery fragments,” says SFEI’s Diana Lin...

Regulatory Teams Coordinate

By Cariad Hayes Thronson In March the San Francisco Estuary Partnership released its Wetlands Regional Monitoring Program Plan, which lays out the science framework for a long-term program to monitor tidal wetlands around the Bay. “The focus of the plan is how we’re going to answer five guiding questions about the status and trends of our tidal wetlands,” says the Partnership’s Heidi Nutters. The framework is only the first phase of what will ultimately be a four-year planning process. Nutters says the team planning for wetlands monitoring is also working closely with the Bay Restoration Regulatory and Integration Team (BRRIT), which comprises representatives from each of the agencies that permit projects.

Bay Not BPA-Free

By Ariel Rubissow Okamoto “BPA is globally detected in human urine,” says scientist Ila Shimabuku of the San Francisco Estuary Institute. BPA, one of a chemical group called bisphenols, is a clear, stable, durable ingredient in plastic bottles, can liners, cash register receipts and many other things we use and touch every day. In 2017, the RMP collected and analyzed 16 bisphenols (including bisphenol A, or BPA) in 22 water samples from around San Francisco Bay. Concentrations of BPA found were similar to those found in other marine and estuarine environments, and at levels approaching the threshold of ecotoxicity. “It’s an intriguing compound in terms of its mechanism for action on our health,” says the Institute’s lead scientist on emerging...

Next Day Delivery: PCBs, Plastics, and Mercury All in One Package

The slow, downstream chemical migration of legacy contaminants like mercury and PCBs into the Bay is something that Lester McKee and his colleagues at the San Francisco Estuary Institute hope to cut short. “The sooner we can stop the inputs of these contaminants,” says SFEI’s Alicia Gilbreath, “the sooner the Bay can have a chance to recover.”

Melissa Foley’s list of concerns as the new head of San Francisco Bay’s premier water-quality program is long: microplastics, pharmaceuticals, PFASs, and other chemicals and contaminants entering the Bay through runoff and treated sewage.

An interdisciplinary scientist trained in marine ecology, with experience in policy, management, and public outreach, Foley assumed leadership late last year of the Regional Monitoring Program for Water Quality in San Francisco Bay (RMP). Along with overseeing the RMP’s rigorous efforts to study and manage Bay pollutants, Foley who comes to the RMP from New Zealand’s Auckland Council, where she used long-term environmental monitoring data to inform both regional and national management and policy strategies, says she’ll draw on her social-science background to include the public in the program’s work. That means calling upon citizens for data collection and getting them involved in improving the health of the Bay, right where they live or work. “We try to develop integrated...

Medicating the Bay

“If you went to the doctor and told them you were taking 69 different pharmaceuticals,” says Emma Rosi of the Cary Institute of Ecosystem Studies, “they would be very concerned with your well-being.” When a study she co-authored detected that number of pharmaceutical compounds in caddisfly larvae along an Australian creek downstream of a treatment plant, it was further evidence that excreted drugs are escaping wastewater facilities and entering food webs. The Bay is no exception. A survey conducted by the San Francisco Estuary Institute found that seventeen commonly used drugs, including antibiotics, antidepressants, and over-the-counter painkillers, could exceed protective thresholds for marine life.

Dioxins Are Sticking Around Nearshore and in Fish, RMP Reports

As the “Fish-SMART” signs on local piers warn, the tissues of fish reeled in from San Francisco Bay waters can contain mercury or PCBs, but a new RMP report reminds us of a third contaminant of concern to human health: dioxins. The report, due out in October 2018 and prepared by staff of the San Francisco Estuary Institute and the SF Bay Regional Water Quality Control Board, confirms that while levels of this toxic contaminant in sediments nearshore have declined somewhat in the last few decades, dioxins persist in the food chain in fish such as white croaker.

Supply Side Synthesis

“Small sensors are the foundation of big science,” says Phil Trowbridge, director of the Bay’s Regional Monitoring Program which has just released a new synthesis report on sediment science. The report, combining the results of eight bodies of work, yielded some surprises concerning how much sediment moves from the Sierra and Bay watersheds to the Golden Gate. “The system is calming down after two huge disruptions,” says David Schoellhammer of the U.S. Geological Survey, referring to hydraulic gold mining and dam building. While the supply remains somewhat stable, how much stays in the Bay and how much ends up in the ocean remains an enduring question. In any case, the sediment supply spotlight is slowly shifting from the Central Valley...

Scrutinizing the Margins

Bay margins are often mucky, fertile, out-of-the-way places. In the last decade, however, the edges of the San Francisco Bay have caught the attention of San Francisco Estuary Institute scientists as unexpected sources of pollution--and, potentially, of solutions. “The idea that you could make a big difference by just cleaning up the margins is attractive because it scales down the problem quite a bit,” says Phil Trowbridge of the Regional Monitoring Program. Historically, scientists considered the Bay akin to a massive bathtub where water pours in, mixes up, and bathes all its contents equally. A 2010 study made the surprising discovery that small fish living in the margins had higher concentrations of PCBs than larger, open water fish. While challenges...

Non-Sticks Stick Around

Common coatings and repellants used in textiles for clothing and furniture are sticking around in San Francisco Bay. “The reason for the lack of declines is not clear,” says researcher Meg Sedlak of the San Francisco Estuary Institute. Some early environmental offenders in this line of fluorinated chemicals (PFASs) have been banned, including one used in Teflon. “In 2006 and 2009, the levels of some PFAS we found in Bay cormorant eggs were among the highest observed concentrations in the world,” says Sedlak.
