Wednesday Top of the Scroll: Billions needed to fund upgrades to meet anticipated wastewater regulations

At least $11 billion would be needed to upgrade wastewater treatment facilities across the Bay Area if regulators impose anticipated stricter environmental rules, according to a regional water board that seeks to protect the San Francisco Bay. The upgrades at dozens of sewage treatment plants, needed to prevent toxic algae blooms and protect fish, would cost an average of $4,000 per household, and consumers may end up funding the improvements. The key culprit? Nitrogen found in urine and fecal matter, which feeds the growth of algae.

New study: US scholars highlight the environmental health implications of plastic use in agriculture

Plastics are also … used in agriculture. Macroplastics are used as protective wraps around mulch and fodder; they cover greenhouses, shield crops from the elements, and are used to make irrigation tubes, sacks, and bottles. … While there are significant benefits to using plastics in agriculture, there are emerging concerns regarding the risks associated with agricultural plastics. Over time, macroplastics slowly break down, fragmented by wind and sunlight into ever-smaller pieces to generate microplastics and nanoplastics. These tiny plastic particles seep into the soil, changing its physical structure and limiting its capacity to hold water.

After massive sewage spill, feds order fixes at L.A. water plant to improve resilience

Years after a massive spill at a Los Angeles water treatment facility dumped millions of gallons of raw sewage into the Pacific, officials with the U.S. Environmental Protection Agency have ordered several improvements at the plant to help prevent another such disaster, even when facing more intense storms from a changing climate. The administrative order of consent, issued this month, requires the Hyperion Water Reclamation Plant in Playa del Rey to make significant fixes to its operations and infrastructure, including improving monitoring systems and overflow channels, after the federal agency’s review of the 2021 spill. The agreement, between the EPA and the Los Angeles Sanitation and Environment division, mandates the updates be implemented by the end of 2025, though some are required to be completed as soon as within 30 days, according to the order.

New study: Say hello to biodegradable microplastics

Microplastics are tiny, nearly indestructible fragments shed from everyday plastic products. As we learn more about microplastics, the news keeps getting worse. Already well-documented in our oceans and soil, we’re now discovering them in the unlikeliest of places: our arteries, lungs and even placentas. Microplastics can take anywhere from 100 to 1,000 years to break down and, in the meantime, our planet and bodies are becoming more polluted with these materials every day. Finding viable alternatives to traditional petroleum-based plastics and microplastics has never been more important. New research from scientists at the University of California San Diego and materials-science company Algenesis shows that their plant-based polymers biodegrade — even at the microplastic level — in under seven months. The paper, whose authors are all UC San Diego professors, alumni or former research scientists, appears in Nature Scientific Reports.

SF allegedly dumps big amounts of sewage into creek during storms

When heavy rain overwhelms wastewater treatment plants in San Francisco, causing stormwater to overflow onto streets and into the bay, sewage is an unfortunate part of the mix.  After heavy rain, the largest recipient of the potent brew of stormwater and sewage in the city is Mission Creek — a channel to the bay that is home to houseboats, walking trails and a kayak launch. At Mission Creek, Islais Creek, another channel at India Basin, and a few locations in between, the city discharges 1.2 billion gallons of “combined sewer discharges” in a typical year, according to the environmental group S.F. Baykeeper, which has notified the city it intends to sue over how such discharges impact the environment. A large portion of the combined sewer overflows — which SFPUC said are composed of 94% treated stormwater and 6% treated wastewater — is making its way without basic treatment into the bay during storms, according to S.F.

Harmful algae detected in Lake Merritt water samples

A rusty red color in Lake Merritt that left lake stewards scrambling to sample the water on Mar. 7 has tested positive for the same algae that caused the devastating harmful algal bloom in 2022.  On Friday, lake stewards sent water samples to labs run by the California Department of Public Health and San Francisco Bay Regional Water Control Board. Unofficial field testing initially detected no harmful algae. However, lab testing confirmed over the weekend the presence of Heterosigma akashiwo, a type of algae often associated with harmful blooms.  Harmful algal blooms, or HABs, occur when certain types of algae grow rapidly and release toxins, lower oxygen levels, and cause other changes in water quality that can kill fish and other marine creatures.

Nutrients from wastewater treatment plants may threaten coastal marine life―should California regulate them?

The State Water Resources Control Board is exploring regulating nutrients emitted from Southern California wastewater treatment plants into the ocean. The controversial move is prompted by concerns that these discharges may accelerate acidification and oxygen loss in the region’s coastal waters, harming nearshore marine life. The wastewater treatment industry says this nutrient regulation is premature. Environmentalists say it’s overdue. … Wastewater effluent from 23 million people is piped offshore in Southern California. The resulting acidity boost could be enough to start dissolving the shells of crabs and small snails called pteropods, which swim near the ocean surface and are a favorite food of many fish and whales. And the resulting oxygen depletion could deprive anchovies, which many commercial fish eat, of their habitat.

New study: Air pollution hides increases in rainfall

We know that greenhouse gas emissions like carbon dioxide should increase rainfall. The emissions heat the atmosphere, causing a one-two punch: warmer oceans make it easier for water to evaporate, and warmer air can hold more water vapor, meaning more moisture is available to fall as rain. But for much of the 20th century, that increase in precipitation didn’t clearly show up in the data. A new study led by researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) finds that the expected increase in rain has been largely offset by the drying effect of aerosols – emissions like sulfur dioxide that are produced by burning fossil fuels, and commonly thought of as air pollution or smog.

Among the factors considered: air pollution and drinking water contaminants, pesticide usage, toxic releases, low birth weight infants, poverty and unemployment rates.

Nevada County rejects controversial gold mining project

After years of controversy, the Nevada County Board of Supervisors unanimously struck down a Grass Valley gold mining project. … Rise Gold first submitted an application to resume gold mining operations at the Idaho Maryland Mine, which is in Grass Valley, in 2019. The site had been inactive since its closure in the 1950s, but Rise Gold said it had untapped potential.  But the company was quickly met with mass opposition. Christy Hubbard, a Grass Valley resident and volunteer for a couple local groups opposing the project … said she was particularly concerned with the potential for mining operations to contaminate or otherwise negatively impact local groundwater supply. As a member of the Wells Coalition, a local group of well owners, and an owner of a well herself, she worried mining could reduce water flows or contaminate them.

Radius Recycling pollutes California waterways, environmental group says

A California environmental group has sued Radius Recycling (RDUS.O), opens new tab, alleging the recycled steel company’s operations are polluting the San Francisco Bay and its tributaries with dirty stormwater runoff. San Francisco Baykeeper filed its lawsuit on Tuesday in Oakland federal court, alleging the company has violated the federal Clean Water Act by failing to stop heavy metals and other pollutants from washing away during storms at four of its facilities in the San Francisco Bay area where cars are dismantled. Radius Recycling was formerly known as Schnitzer Steel, and was recognized last year by the research firm Corporate Knights as the world’s most sustainable company due to its reported improvements in things like energy, carbon, water and waste use.

Blog: New analysis shows widespread PFAS contamination of tap water in CA

Toxic “forever” PFAS chemicals are a serious environmental health issue in California and across the globe, linked to numerous health harms. California has been a leader in addressing PFAS, including banning PFAS use in multiple products (such as fire-fighting foam and textiles). Yet PFAS continue to be used in hundreds of different consumer and industrial products and our new analysis, released today, shows drinking water sources serving up to 25 million Californians are or have been contaminated with PFAS.  A bill by Senator Nancy Skinner, also introduced today, proposes a much needed comprehensive, efficient, and health-protective approach to phasing out the use of these highly problematic chemicals. Such preventative legislation will be key to helping to address the PFAS crisis. We also need to tackle current contamination by setting drinking water standards for PFAS.

North Bay nonprofit removes deadly ghost nets from Great Pacific Garbage Patch

If anyone can accurately describe the massive scope of the plastics problem in the Pacific, it’s [Mary] Crowley, the founder and director of Ocean Voyages Institute, a nonprofit based in Sausalito. She didn’t, however, set out to become an expert on the topic. In fact, the seasoned mariner was happy operating her yacht chartering company and logging 125,000 miles sailing the world. Yet with each passing year, she noticed more and more plastic in the ocean. Finally, Crowley knew she had to act. Since 2009, she’s led eight cleanup expeditions, hauling more than 700,000 pounds of plastic out of our planet’s blue heart and transporting it to recyclers.

New report unveils what plastic makers knew about recycling

The plastics industry has worked for decades to convince people and policymakers that recycling would keep waste out of landfills and the environment. Consumers sort their trash so plastic packaging can be repurposed, and local governments use taxpayer money to gather and process the material. Yet from the early days of recycling, plastic makers, including oil and gas companies, knew that it wasn’t a viable solution to deal with increasing amounts of waste, according to documents uncovered by the Center for Climate Integrity. … But the industry appears to have championed recycling mainly for its public relations value, rather than as a tool for avoiding environmental damage, the documents suggest.

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.
