NSW waste industry faces crackdown on recycled soil after asbestos found in more than half facilities tested

Wednesday, August 7, 2024

The New South Wales environment watchdog has vowed to crack down on the waste industry after new tests found asbestos at seven of 13 facilities producing or handling cheap landscaping products.A 15-month Guardian Australia investigation revealed earlier this year that the Environment Protection Authority (EPA) had failed to act after compliance campaigns in 2013 and 2019 found potentially contaminated products had been distributed across the state – including at childcare centres, schools, residential areas and parks – thanks to widespread breaches by the industry.The chief executive of the EPA, Tony Chappel, said the watchdog was now considering “significant changes” to the regulations that govern recovered fines – soil fill made from recycled construction and demolition waste.The fill is used in place of virgin materials in construction projects and public spaces such as parks. It is also sold for home use by landscape and garden stores.The EPA visited the 13 facilities to carry out new testing in late 2023 and early 2024. In addition to the asbestos found at seven sites, six had recovered fines that contained glass and chemicals above the legal limits and pH levels outside the allowed range.Chappel said the industry had been given ample opportunity to improve “but it’s time to reassess the regulatory settings”.“The levels of non-compliance we’re seeing are concerning and it’s frustrating to see these issues continue despite working with industry over many years,” he said in a statement.The watchdog will now review the regulations and will consider changes to the testing and sampling regime, where soil products made from recovered fines can be used and how producers are required to manage stockpiles “to improve environmental outcomes across the industry”.“Significant changes to the rules governing recovered fines are being considered by the NSW EPA,” Chappel said. “We’ll also work with industry to improve quality control at the source of material and tracking of that material as it moves through the supply chain.”As a result of the latest tests, nine facilities were required to dispose of more than 600 tonnes of non-compliant recovered fines.The EPA said two facilities had already supplied recovered fines from non-compliant stockpiles to customers and were required to organise an asbestos assessor to assess the risk for each customer.The EPA did not name the seven facilities where it detected asbestos, but prevention notices published on the EPA register show that Rock & Dirt Recycling in South Windsor, operated by N Moit & Sons, and Gow Street Recycling in Padstow were among them. The EPA also did not name the six facilities that it found had breached limits for glass, chemicals and other contaminants and pH levels.Separately, fines totalling $45,000 were issued to three Sydney facilities – Rock & Dirt Recycling, Aussie Skips Recycling in Strathfield South and Canterbury-Bankstown council’s Kelso Waste, Storage and Transfer facility at Milperra – for alleged licence breaches on standards for managing construction waste, including failure to properly label stockpiles.More fines were likely to come, the EPA said, without identifying which facilities might be affected.A Canterbury-Bankstown council spokesperson said the council did not produce recovered fines at Kelso but a “stockpile of recycled soil supplied from an external company did show samples of excess glass and council has had the company take the materials back”.Rock & Dirt Recycling, Gow Street Recycling and Aussie Skips Recycling did not respond to requests for comment.‘I wasn’t crying wolf all those years ago’The full results of the EPA’s 2013 and 2019 investigations, as well as internal calls from its own officials to crack down on the sector, remained secret until they were obtained by Guardian Australia last year under NSW government information public access laws.In one internal document, the EPA estimated up to 658,000 tonnes of material that had not complied with state regulations could have been used in the community every year.But the EPA walked away from a proposal to tighten regulations in 2022 after opposition from the waste industry.skip past newsletter promotionOur Australian morning briefing breaks down the key stories of the day, telling you what’s happening and why it mattersPrivacy Notice: Newsletters may contain info about charities, online ads, and content funded by outside parties.

The New South Wales environment watchdog has vowed to crack down on the waste industry after new tests found asbestos at seven of 13 facilities producing or handling cheap landscaping products.

A 15-month Guardian Australia investigation revealed earlier this year that the Environment Protection Authority (EPA) had failed to act after compliance campaigns in 2013 and 2019 found potentially contaminated products had been distributed across the state – including at childcare centres, schools, residential areas and parks – thanks to widespread breaches by the industry.

The chief executive of the EPA, Tony Chappel, said the watchdog was now considering “significant changes” to the regulations that govern recovered fines – soil fill made from recycled construction and demolition waste.

The fill is used in place of virgin materials in construction projects and public spaces such as parks. It is also sold for home use by landscape and garden stores.

The EPA visited the 13 facilities to carry out new testing in late 2023 and early 2024. In addition to the asbestos found at seven sites, six had recovered fines that contained glass and chemicals above the legal limits and pH levels outside the allowed range.

Chappel said the industry had been given ample opportunity to improve “but it’s time to reassess the regulatory settings”.

“The levels of non-compliance we’re seeing are concerning and it’s frustrating to see these issues continue despite working with industry over many years,” he said in a statement.

The watchdog will now review the regulations and will consider changes to the testing and sampling regime, where soil products made from recovered fines can be used and how producers are required to manage stockpiles “to improve environmental outcomes across the industry”.

“Significant changes to the rules governing recovered fines are being considered by the NSW EPA,” Chappel said. “We’ll also work with industry to improve quality control at the source of material and tracking of that material as it moves through the supply chain.”

As a result of the latest tests, nine facilities were required to dispose of more than 600 tonnes of non-compliant recovered fines.

The EPA said two facilities had already supplied recovered fines from non-compliant stockpiles to customers and were required to organise an asbestos assessor to assess the risk for each customer.

The EPA did not name the seven facilities where it detected asbestos, but prevention notices published on the EPA register show that Rock & Dirt Recycling in South Windsor, operated by N Moit & Sons, and Gow Street Recycling in Padstow were among them.

The EPA also did not name the six facilities that it found had breached limits for glass, chemicals and other contaminants and pH levels.

Separately, fines totalling $45,000 were issued to three Sydney facilities – Rock & Dirt Recycling, Aussie Skips Recycling in Strathfield South and Canterbury-Bankstown council’s Kelso Waste, Storage and Transfer facility at Milperra – for alleged licence breaches on standards for managing construction waste, including failure to properly label stockpiles.

More fines were likely to come, the EPA said, without identifying which facilities might be affected.

A Canterbury-Bankstown council spokesperson said the council did not produce recovered fines at Kelso but a “stockpile of recycled soil supplied from an external company did show samples of excess glass and council has had the company take the materials back”.

Rock & Dirt Recycling, Gow Street Recycling and Aussie Skips Recycling did not respond to requests for comment.

‘I wasn’t crying wolf all those years ago’

The full results of the EPA’s 2013 and 2019 investigations, as well as internal calls from its own officials to crack down on the sector, remained secret until they were obtained by Guardian Australia last year under NSW government information public access laws.

In one internal document, the EPA estimated up to 658,000 tonnes of material that had not complied with state regulations could have been used in the community every year.

But the EPA walked away from a proposal to tighten regulations in 2022 after opposition from the waste industry.

Among the revelations was a 2019 finding that 43% of facilities that produce recovered fines had gamed the testing regime – which was designed to limit toxic chemicals and physical contaminants such as glass and rigid metals in the landscaping products – by asking private laboratories to repeatedly test samples found to contain contamination until they achieved an acceptable result.

Waste facilities making recovered fines are required to test their product for hazardous contaminants, such as lead, and report results to the EPA if they exceed legislated thresholds. Retesting of recovered fines is not prohibited, but if any test shows a sample has exceeded a contaminant threshold, the product is considered non-compliant.

The facilities are not required to specifically test for asbestos, but the recycling and reuse of asbestos in any form is prohibited.

In May, Guardian Australia revealed that some of the biggest waste companies in the state – including Bingo Industries, Aussie Skips Recycling, Benedict Recycling and KLF Holdings – were among those named in state parliament as having broken testing and sampling rules or to have requested retesting in 2013 or 2019.

Jason Scarborough led the 2013 investigation which, among its recommendations, said use of the products should be restricted to deeper construction works and its use for landscaping should be prohibited.

He said breaches by the industry represented both a regulatory and a market failure. “If we are moving to a circular economy, consumers have to have confidence that the recycled materials they may be buying are safe and fit for purpose.”

In April, Guardian Australia bought four recovered fines products at Sydney landscape stores and had samples of each tested by two private laboratories.

Two did not comply with state regulations on pH levels and one was found to contain asbestos fibres. One of the products that passed the laboratory tests contained large physical contaminants, including glass and a metal screw.

The EPA has confirmed it is investigating the product found to contain asbestos and looking into the original source of the material.

The results prompted the EPA to express concern about the “poor product and levels of non-compliance we are seeing in the industry”.

Chappel said the regulator would also closely consider any findings of a review by the office of the NSW chief scientist into minute traces of asbestos in recovered products and whether they posed a risk to public health.

The findings are expected later this year.

As Fast Fashion's Waste Pollutes Africa's Environment, Designers in Ghana Are Finding a Solution

In a sprawling secondhand clothing market in Ghana’s capital, early morning shoppers jostle as they search through piles of garments, eager to pluck a bargain or a designer find from the stalls selling used apparel from the West

ACCRA, Ghana (AP) — In a sprawling secondhand clothing market in Ghana’s capital, early morning shoppers jostle as they search through piles of garments, eager to pluck a bargain or a designer find from the stalls selling used and low-quality apparel imported from the West. At the other end of the street, an upcycled fashion and thrifting festival unfolds with glamour and glitz. Models parade along a makeshift runway in outfits that designers created out of discarded materials from the Kantamanto market, ranging from floral blouses and denim jeans to leather bags, caps and socks.The festival is called Obroni Wawu October, using a phrase that in the local Akan language means “dead white man’s clothes.” Organizers see the event as a small way to disrupt a destructive cycle that has made Western overconsumption into an environmental problem in Africa, where some of the worn-out clothes end up in waterways and garbage dumps. “Instead of allowing (textile waste) to choke our gutters or beaches or landfills, I decided to use it to create something ... for us to use again,” said Richard Asante Palmer, one of the designers at the annual festival organized by the Or Foundation, a nonprofit that works at the intersection of environmental justice and fashion development.Ghana is one of Africa's leading importers of used clothing. It also ships some of what it gets from the United Kingdom, Canada, China and elsewhere to other West African nations, the United States and the U.K., according to the Ghana Used Clothing Dealers Association. Some of the imported clothes arrive in such poor shape, however, that vendors dispose of them to make room for the next shipments. On average, 40% of the millions of garments exported weekly to Ghana end up as waste, according to Neesha-Ann Longdon, the business manager for the Or Foundation’s executive director. The clothing dealers association, in a report published earlier this year on the socioeconomic and environmental impact of the nation’s secondhand clothing trade, cited a much lower estimate, saying only 5% of the items that reach Ghana in bulk are thrown out because they cannot be sold or reused. In many African countries, citizens typically buy preowned clothes — as well as used cars, phones and other necessities — because they cost less than new ones. Secondhand shopping also gives them a chance to score designer goods that most people in the region can only dream of.But neither Ghana's fast-growing population of 34 million people nor its overtaxed infrastructure is equipped to absorb the amount of cast-off attire entering the country. Mounds of textile waste litter beaches across the capital, Accra, and the lagoon which serves as the main outlet through which the city’s major drainage channels empty into the Gulf of Guinea.“Fast fashion has taken over as the dominant mode of production, which is characterized here as higher volumes of lower-quality goods,” Longdon said.Jonathan Abbey, a fisherman in the area, said his nets often capture textile waste from the sea. Unsold used clothes “aren’t even burned but are thrown into the Korle Lagoon, which then goes into the sea,” Abbey said.The ease of online shopping has sped up this waste cycle, according to Andrew Brooks, a King’s College London researcher and the author of “Clothing Poverty: The Hidden World of Fast Fashion and Second-hand Clothes.” In countries like the U.K., unwanted purchases often end up as charity donations, but clothes are sometimes stolen from street donation bins and exported to places where the consumer demand is perceived to be higher, Brooks said. Authorities rarely investigate such theft because the clothes are "seen as low-value items,” he said.Donors, meanwhile, think their castoffs are “going to be recycled rather than reused, or given away rather than sold, or sold in the U.K. rather than exported overseas,” Brooks said.The volume of secondhand clothing sent to Africa has led to complaints of the continent being used as a dumping ground. In 2018, Rwanda raised tariffs on such imports in defiance of U.S. pressure, citing concerns the West's refuse undermined efforts to strengthen the domestic textile industry. Last year, Ugandan President Yoweri Museveni said he would ban imports of clothing “from dead people.”Trade restrictions might not go far in either reducing textile pollution or encouraging clothing production in Africa, where profits are low and incentives for designers are few, experts say.In the absence of adequate measures to stop the pollution, organizations like the Or Foundation are trying to make a difference by rallying young people and fashion creators to find a good use for scrapped materials.Ghana's beaches had hardly any discarded clothes on them before the country's waste management problems worsened in recent years, foundation co-founder Allison Bartella said. “Fast forward to today, 2024, there are mountains of textile waste on the beaches,” she said.Copyright 2024 The Associated Press.

What Bird Flu in Wastewater Means for California and Beyond

Wastewater in several Californian cities, including San Francisco and Los Angeles, recently tested positive for bird flu. But understanding disease risk and exposure to humans isn’t so straightforward

Since the first avian influenza outbreaks hit the U.S. early this year, health and agriculture experts have struggled to track the virus’s spotty path as it spreads in dairy cow herds and an unknown number of humans. Infection risk still seems low for most people, but dairy workers and others directly exposed to cows have been getting sick. Canada’s first human case was just reported, in a teenager who is in critical condition. To get a better handle on the unsettling situation, scientists are picking up a pathogen-hunting tool that’s been powerful in the past: wastewater surveillance.In the past couple of weeks, wastewater samples in several locations mostly scattered around California—including the cities of Los Angeles, San Francisco, Sacramento and San Jose—tested positive for genetic material from the bird flu virus, H5N1. The Centers for Disease Control and Prevention’s National Wastewater Surveillance System reported detections at 14 sites in California during a collection period that ended on November 2. As of November 13, across the U.S., 15 sites monitored by WastewaterSCAN, a project run by Stanford University and Emory University researchers, reported positive samples this month. But finding H5N1 material in wastewater doesn’t necessarily mean there’s a risk to human health, says WastewaterSCAN’s co-director Alexandria Boehm, a civil and environmental engineer at Stanford University.Analyzing trace amounts of viral genetic material, often shed by fecal matter in sewers, can alert scientists and public health experts to a possible increase in community infections. Wastewater sampling became instrumental in forecasting COVID cases across the U.S., for instance. But the way H5N1 affects both animal and human populations complicates identifying sources and understanding disease risk. H5N1 can be deadly in poultry. Cattle usually recover from symptoms—such as fever, dehydration and reduced milk production—but veterinarians and farmers are reporting that cows have been dying at higher rates in California than in other affected states. Cats that drink raw milk from infected cows can develop deadly neurological symptoms. The current cases in humans haven’t caused any known deaths (most people have flulike symptoms, although some develop eye infections), but past major outbreaks outside of the U.S. have resulted in fatalities.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.Scientific American spoke with Boehm about the latest bird flu detections in wastewater and the ways that scientists are using these data to better track and understand disease prevalence and exposure—among animals and humans both.[An edited transcript of the interview follows.]When did WastewaterSCAN start tracking H5N1?We noticed something very unusual in Amarillo, Tex. [In the spring of 2024,] after flu season, we saw really high levels of influenza A [one of the four flu virus types that infect humans] RNA nucleic acids in their wastewater. This was surprising because we know influenza A in wastewater tracks with cases in the community—but there were not very many cases in the community, and it was after flu season. We also then heard on the news that they had discovered cattle infected with avian influenza in the same area in Texas. So we worked in collaboration with the local wastewater treatment plants and public health officers to test the wastewater. And we found that, indeed, it was H5 [a subtype of avian influenza A virus] in their waste stream. We determined that most of that H5 was coming from legal discharges into the sanitary sewer from milk processing plants.Then when we scaled the H5 assay across the country, we were finding it in locations where, shortly thereafter, cattle were being identified as being infected [with the virus]. In June the CDC actually sent memos to the states asking them to try to measure H5 in wastewater, recognizing that the measurements can help to understand the extent and duration of the outbreak in the U.S.Has wastewater analysis been able to trace cases to any sources?We can’t always rule out that it’s wild birds or poultry or humans, but overall the preponderance of evidence suggests most of the inputs are likely from cow milk. That cow milk is getting into consumer homes, where people are disposing of it down the drain. I’m sure you have poured out milk down your sink—I know I have. It’s also coming from permitted operations where people are making cheese or yogurt or ice cream, and they might be starting with a milk product that has the avian influenza nucleic acids in it.I want to stress that the milk in people’s homes that might have the avian influenza RNA is not infectious or a threat to human health. It’s just a marker that some milk got into the food chain that originally had the virus in it. It’s killed because milk products are pasteurized—and that’s, by the way, why drinking raw milk or eating raw cheeses right now is not really recommended. The RNA that makes up the genome of these viruses is extremely stable in wastewater. It’s even stable after pasteurization. So you pasteurize the raw milk, and the RNA is still present at about the same concentrations.Detecting it in the wastewater does not mean there’s a risk to human health. What it does mean is that there are still infected cattle that are around the vicinity, and work still needs to be done to identify those cattle and remove their products from the food chain, which is the goal of the officials that are in charge of that aspect of the outbreak.How might we be able to better determine where the viral genetic material is coming from and assess human infection rates?It is very difficult because genetically the virus is not different [between sources]. It’s not like we can say, “Oh, the one in humans is going to be like this, and so let’s look for that.” We’re working really closely with public health departments that are really proactive in sequencing positive influenza cases. If we do start seeing it in [more] people, we will likely know it because we’ll see differences in the wastewater.I don’t want to be alarmist because right now the risk of getting H5N1 is very minimal, and the symptoms are really mild. But I think one of the concerns is that the virus could mutate during this influenza season coming up. Somebody who’s infected with [seasonal influenza] could also get infected with H5N1, and then it could maybe create a new strain that could be more severe. We’re hoping that the wastewater data, along with all the other data that people and agencies are collecting, will together help figure out what’s going on and protect public health better.What are trends are you seeing in your surveillance right now?Most recently, California is just lighting up. A lot of the wastewater samples in California are coming back as positive, even in locations that are very urban—such as the Bay Area and in Los Angeles. The question is: Why? In some of these locations, there actually are small operations where people are making dairy products with milk. But another explanation, like I mentioned earlier, is just the wasting of milk products.How do H5N1 levels in wastewater correlate to infections in animals?We’re sort of seeing it as an early indicator, or concurrent indicator, of cattle in the vicinity being infected with avian influenza. The first detections were in Texas, and we saw a lot of detections in Michigan for a while, and now the hot spot is California. As scientists, we’re going to analyze all this in the future. But anecdotally, the H5 detections in wastewater are following along with when herds are identified, and then once it’s sort of under control, we stop seeing it.Public health officials are using the data to say, “Okay, we got a positive in this location. What are the different sources that could account for it? Have we tested all the cattle that are contributing milk products to industries in this sewer shed? Have we gotten rid of all the infected herds in our state, because now we’re not getting any positives in the wastewater?”How else are scientists and officials staying on top of cases and spread?The [U.S. Department of Agriculture] and different entities around the country are pursuing it from an animal health perspective and a food safety perspective. So there is testing of cattle herds and milk products. There’s also testing of poultry, and then there’s testing of workers that are in contact with infected herds and infected poultry. On the clinical side, there is a push to get influenza-positive samples sequenced to understand what kind of influenza it is, as sort of a safety net to see if there might be some avian influenza circulating in people. So far, cases have been in people who are actually exposed to infected animals, who are working on farms, and perhaps in some of their family members.How has tracking H5N1 been different from or similar to COVID or other pathogens?All the other pathogens that we track have been conceptually similar to COVID, where humans are the source [of pathogenic material in wastewater]. We know that the occurrence of the viral or fungal material in wastewater match the cases. Bird flu is the first example where we’re using wastewater to track something that is primarily not, at least right now, from a human source but has potential human health implications for different reasons. It’s been a really great case study of how wastewater can be used not only for tracking human illness but also zoonotic pathogens—pathogens that affect animals. So now we’re thinking about what else wastewater could be used for. What other kinds of animal byproducts end up in the waste stream that might contain biomarkers of infectious disease? H5 is our first example, and I’m sure there will be more.

Generative AI Could Generate Millions More Tons of E-Waste by 2030

Generative AI could saddle the planet with heaps more hazardous waste

November 14, 20243 min readGenerative AI Is Poised to Worsen the E-Waste CrisisGenerative AI could saddle the planet with heaps more hazardous waste By Saima S. IqbalA server room in a data center. Every time generative artificial intelligence drafts an e-mail or conjures up an image, the planet pays for it. Making two images can consume as much energy as charging a smartphone; a single exchange with ChatGPT can heat up a server so much that it requires a bottle’s worth of water to cool. At scale, these costs soar. By 2027, the global AI sector could annually consume as much electricity as the Netherlands, according to one recent estimate. And a new study in Nature Computational Science identifies another concern: AI’s outsize contribution to the world’s mounting heap of electronic waste. The study found that generative AI applications alone could add 1.2 million to five million metric tons of this hazardous trash to the planet by 2030, depending on how quickly the industry grows.Such a contribution would add to the tens of millions of tons of electronic products the globe discards annually. Cell phones, microwave ovens, computers and other ubiquitous digital products often contain mercury, lead or other toxins. When improperly discarded, they can contaminate air, water and soil. The United Nations found that in 2022 about 78 percent of the world’s e-waste wound up in landfills or at unofficial recycling sites, where laborers risk their health to scavenge rare metals.The worldwide AI boom rapidly churns through physical data storage devices, plus the graphics processing units and other high-performance components needed to process thousands of simultaneous calculations. This hardware lasts anywhere from two to five years—but it’s often replaced as soon as newer versions become available. Asaf Tzachor, a sustainability researcher at Israel’s Reichman University, who co-authored the new study, says its findings emphasize the need to monitor and reduce this technology’s environmental impacts.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.To calculate just how much generative AI contributes to this problem, Tzachor and his colleagues examined the type and volume of hardware used to run large language models, the length of time that these components last and the growth rate of the generative AI sector. The researchers caution that their prediction is a gross estimate that could change based on a few additional factors. More people might adopt generative AI than the authors’ models anticipate, for example. Hardware design innovations, meanwhile, could reduce e-waste in a given AI system—but other technological advances can make systems cheaper and more accessible to the public, increasing the number in use.This study’s biggest value comes from its attention to AI’s broad environmental impacts, says Shaolei Ren, a researcher at the University of California, Riverside, who studies responsible AI and was not involved in the new research. “We might want these [generative AI] companies to slow down a bit,” he says.Few countries mandate the proper disposal of e-waste, and those that do often fail to enforce their existing laws on it. Twenty-five U.S. states have e-waste management policies, but there is no federal law that requires electronics recycling. In February Democratic Senator Ed Markey of Massachusetts introduced a bill that would require federal agencies to study and develop standards for AI’s environmental impacts, including e-waste. But that bill, the Artificial Intelligence Environmental Impacts Act of 2024 (which has not passed the Senate), would not force AI developers to cooperate with its voluntary reporting system. Some companies, however, claim to be taking independent action. Microsoft and Google have pledged to reach net zero waste and net zero emissions respectively by 2030; this would likely involve reducing or recycling AI-related e-waste.Companies that use AI have numerous options to limit e-waste. It’s possible to squeeze more life out of servers, for instance, through regular maintenance and updates or by shifting worn-out devices to less-intensive applications. Refurbishing and reusing obsolete hardware components can also cut waste by 42 percent, Tzachor and his co-authors note in the new study. And more efficient chip and algorithm design could reduce generative AI’s demand for hardware and electricity. Combining all these strategies would reduce e-waste by 86 percent, the study authors estimate.There’s another wrinkle as well: AI products tend to be trickier to recycle than standard electronics because the former often contain a lot of sensitive customer data, says Kees Baldé, an e-waste researcher at the United Nations Institute for Training and Research, who wasn’t involved with the new study. But big tech companies can afford to both erase that data and properly dispose of their electronics, he points out. “Yes, it costs something,” he says of broader e-waste recycling, “but the gains for society are much larger.”

Demolition of Homes Built on a New Orleans Toxic Waste Site Begins

Demolition of abandoned homes constructed on a toxic waste site has begun in New Orleans

NEW ORLEANS (AP) — Demolition of abandoned homes constructed on a toxic waste site began Wednesday in New Orleans, where Environmental Protection Agency Administrator Michael Regan joined local officials touting plans to replace the homes with a solar energy farm.Homes in the area known as Gordon Plaza were built in the 1970s and 1980s and marketed to Black people and low- and middle-income residents who weren’t told that the site was a one-time landfill. As awareness grew and environmentalists raised concerns, the area was named a federal Superfund cleanup site in 1994. Amid reports that the soil was contaminated with lead and carcinogens, including arsenic, residents began a decades-long effort to be relocated at government expense. The city set aside $35 million in 2022 to pay for buyouts of residents’ homes.Shortly before excavators began tearing into the first house, Regan commended Mayor LaToya Cantrell, U.S. Rep. Troy Carter, City Council members and activists who worked to bring about the buyouts.Regan said the moment was “bittersweet” during a pre-demolition news conference livestreamed by WWL-TV. “After all, this is the demolition of a neighborhood that, despite all of the issues that they face, it holds sentimental value to so many people,” Regan said. “This is where so many people bought their first home after years of work and countless sacrifices.”City Council members Oliver Thomas and Eugene Green said they had family members who had moved into the subdivision with high hopes, only to learn of the environmental dangers. “I’m pleased to be here today in recognition of the families that went through so much for so long," Green said.New Orleans officials say they hope to use power from a solar farm planned for the site to supplement energy sources for the city's street drainage pump system.

Since he moved to Bayview at five years old, Darryl Watkins wondered why a neglected lot, called 900 Innes, was closed off. He often played basketball at India Basin Shoreline Park next to the yard sloping into the Bay, and peeked through the fence to find dirt, trash, neglected buildings, and a dilapidated cottage that housed shipbuilders over a century ago. It was in such disrepair that Watkins never imagined it could be a park. The parks he liked had clean bathrooms, trees, and nature—things found outside of his community. Over $200 million and four years of remediation and construction later, the fences enclosing the yard finally opened on October 19. It’s the first time residents will be able to step foot on the completely transformed property, with two new piers, a floating dock, a food pavilion, and access to some of San Francisco’s last remaining natural shoreline. The 900 Innes opening marks the completion of the second phase of a three-part plan that combines the existing India Basin Shoreline Park and 900 Innes property into one 10-acre waterfront park, while closing a major gap on the 13-mile San Francisco Blue Greenway-Bay Trail.  The 900 Innes Waterfront Park unveiling on October 19; section of the San Francisco Blue Greenway-Bay Trail; Mayor London Breed cutting the ribbon on opening day (Photos by Jillian Magtoto) The San Francisco Recreation and Parks Department (RPD)  is calling it “San Francisco’s Next Great Park” that will bring the city’s southern waterfront up to par with iconic public spaces such as Crissy Field, Washington Square Park, and Golden Gate Park. Beyond the flashy claims, the RPD wants the park to benefit local residents long burdened by a history of industrial pollution. “It’s southeast communities where the city has put all of its crap. We put our water treatment plants, we put our power plants, we put everything that no one else wanted in the city,” says David Froehlich, the RPD project manager of remediation for all three India Basin Park projects. “Whether we built a park here or not, we always promise the community that we would leave this site cleaner than it was when we purchased it.” Some Bayview-Hunters Point locals aren’t convinced RPD has done enough, while others are hopeful the park was indeed adequately remediated. “It’s been a long time coming,” says Jill Fox, who has lived across the street from 900 Innes Ave for over 30 years. “Our fingers are crossed that it will be a good thing for our community.” The old shipyard at 900 Innes Ave along San Francisco’s India Basin has long worn the past of industrial boating. The blacksmith shop, boatyard office, and tool shed had partially or almost completely collapsed. Old overhead power lines sparked and caught on fire, according to residents. The ground was blanketed with concrete, brick, glass, and wood fragments that thickened up to forty feet down into the water. It was sold to private businesses in 1991 and passed between different owners for decades, serving various roles as a homeless encampment, illegal drug lab, and construction storage yard. It remained undeveloped and inaccessible to the public until community members advocated for the property to be acquired by the RPD in 2014. “I always thought 900 Innes would be much better as a respite, a place to be with nature,” says Fox, who participated in the effort towards the lot’s public acquisition. “RPD had the funds and owned properties on either side of it.” A rendition of the India Basin Waterfront Park Project, the combination of the renovated India Basin Shoreline Park and the neighboring 900 Innes property.

Soil samples in 2017 revealed elevated levels of PCBs, petroleum hydrocarbons, and heavy metals from painting, waterproofing, and other boating activities, especially concentrated near boat launch sites. Before it could ever become a place for people, a significant cleanup was in order. “There were a lot of regulatory agencies that were involved,” says Froehlich. “And permits that I wasn’t typically used to.” Local, state, and federal agencies oversaw the remediation, including the Army Corps of Engineers, the Environmental Protection Agency, California State Water Board, and the San Francisco Water Quality Control Board. They monitored the site as the RPD installed a temporary water barrier to push back the Bay water, like the rim of a massive inflatable pool, to remove layers of concrete and up to two feet of contaminated soil. In 2022, the last year of remediation, they discovered the contaminants spread deeper. They found lead, mercury, and PCBs up to seven feet below ground, according to the Remedial Action Plan. “We excavated down to a completely clean site and put clean cover on top of that, using soil from a virgin quarry in the East Bay,” says Froehlich. “So, in theory, it’s a completely clean site.” Water barrier installed during remediation (Photo by San Francisco Recreation and Parks Department)Still, some community advocates remain unsure. “We support a new and improved park in theory, but as long as it can be clean and safe,” says Bradley Angel, the director of Greenaction, a San Francisco-based health and environmental justice nonprofit. The city’s only Superfund site is just a third of a mile southeast from 900 Innes, a former naval laboratory that leaked petroleum, pesticides, and radioactive waste into the ground for 40 years. This contamination remained unknown until 2012, when the Navy discovered that the federally-contracted consulting firm Tetra Tech EC falsified their data. While the Navy allowed Tetra Tech to clear itself in an internal investigation, whistleblowers in 2017 alleged that the Navy mishandled cleanup efforts and covered up the extent of the pollution, in a lawsuit led by Greenaction against the EPA and Navy. Still, the RPD is confident that the former naval site has no effect on 900 Innes. No radioactive chemicals were found, according to RPD communications manager, Daniel Montes. But advocates like Angel haven’t forgotten.  “Greenaction and the community for many years regarding the Hunters Point shipyard Superfund site have called for independent community oversight of all testing and cleanup activities, and that’s fallen on deaf ears,” says Bradley. “Greenaction believes that there needs to be independent retesting of India Basin and the whole shoreline in Bayview, because we do not trust for good reason.” Angel is not just concerned by what might be in the ground at 900 Innes, but also what might be in the air. South of the new park, at 700 Innes, is a planned residential and commercial complex by BUILD LLC, a private developer that agreed to give about six acres of land to the RPD. Originally planned alongside the 900 Innes property, the RPD issued a Draft Environmental Impact Report (EIR) in 2017 that combined the projected effects of both sites. Still the latest available EIR, it concluded that the joint project “would generate emissions that could expose sensitive receptors to substantial pollutant concentrations significant and unavoidable with mitigation.” Bayview-Hunters Point sees about 97 more annual cases of asthma-related emergency room visits and three more heart attack-related visits per ten thousand people than greater San Francisco. The community is among four neighborhoods in the city with the highest rate of preventable hospitalizations related to air pollution, according to a San Francisco Public Utility Commission 2017 study.  While 700 Innes has been delayed, Angel says once construction begins, the area “won’t be a safe place for some people.” “I can’t comment on the 700 Innes impacts for air quality and what that development would do,” says Froehlich. But noted that with construction complete, now and going forward, 900 Innes park will have a very small impact on air quality.

The park opening commenced the arrival of Rocking the Boat—a nonprofit that provides nature and boat education for youth from Hunts Point, New York, with origins similar not just in name. Based in an underserved community in the Bronx, home to aging treatment plants and heavy transportation emissions, the nonprofit was offered an opportunity from the RPD to continue their work at the shop building near the floating docks at 900 Innes, fixing boats and offering rides on the water every Sunday. In March 2025, they will recruit 16 eighth graders from the community to build a 14-foot whitehall from scratch, a type of rowboat that hauled people and small goods in both New York City and San Francisco into the 19th century. Their work will  just involve wood and a little bit of glue,” says Adam Green, who founded Rocking the Boat in 2001. “My hope is that the RPD uses shavings and sawdust we collect for mulch.” The park is newly landscaped with upland sage and native vegetation that run along concrete paths. Mulch and wood chips cover the areas in between.

He will be working at the same Shipwright’s Cottage he saw through the fence not long ago, now a museum, to welcome visitors when they first walk in.  “I think they brought me on to be a connector between the community and the project,” says Watkins. “Having people that really care about this park will help maintain it for years to come.” Darryl Watkins at 900 Innes Ave, just next to Shipwright’s Cottage (Photo by Jillian Magtoto)
