How One Utah Community Fought the Fracking Industry — and Won

By Tara Lohan
A sign at the north end of Kanab, Utah, proclaims the town of 4,300 to be "The Greatest Earth on Show."
It's a rare case of truth in advertising.
Kanab sits just seven miles north of the Arizona state line, at the crossroads of some of the Southwest's most beautiful places. In every direction a geologic wonderland awaits. To the north is Zion National Park with its breathtaking valley of 2,000-foot-tall rust and white sandstone cliffs. The sweeping expanse of Grand Staircase-Escalante National Monument stretches to the east of town, and just to the south you'll find the Grand Canyon's North Rim.
You don't even need to leave Kanab, which is ringed by the famously red-hued Vermillion Cliffs, to get socked by jaw-dropping beauty.
It's this landscape that drew Susan Hand to Kanab 25 years ago when she opened Willow Canyon Outdoor to sell gear, maps, books and coffee to local and visiting adventurers. And it's this landscape and the community's gateway-to-the-wonderland experience, the economic bedrock of this tourism-dependent town, that she worried would be destroyed by a new industrial project proposed for development 10 miles north of town last year.

There, a company called Southern Red Sands LLC had announced plans to build a facility to mine and process massive amounts of sand for use by oil and gas companies conducting hydraulic fracturing. The sand is a lesser-known but substantial aspect of the fracking process. Round grains of silica sand serve as a "proppant" to keep underground fissures in the shale open as oil and gas are pumped out. Fracking a single well can require thousands of tons of sand.
"I really wanted to keep an open mind, but the more I learned about the project, the more concerned I got," Hand told The Revelator when I visited Kanab in September.
She had reason to be worried. The first decade of the fracking boom relied heavily on so-called "frac sand" sourced mostly from Midwest states like Minnesota and Wisconsin, where mining reduced verdant green hills to piles of dust.

But mining in the Midwest has its limits. Sand is expensive to ship across the country, so as fracking has taken off in Utah, Texas and New Mexico, companies have looked to find more local sources to trim costs.
That's when the proposed mine in Kanab entered the story.
Southern Red Sands, a two-person start-up backed by Utah real-estate developer Kem Gardner, hoped to establish the region's next frac sand mine in a scenic area of state-owned lands outside Kanab called Red Knoll.
City and county officials quickly gave their blessing — and a combined 1,200 acre-feet of water rights a year — after only cursory consideration.
But residents became concerned about impacts to scenic beauty, water resources and local businesses. They teamed up to fight back, forming a community group called Keep Kanab Unspoiled.
It was beginning to feel like a familiar story.
The struggle between extractive industries and environmental protection is not a new one in Utah. A fight is still raging nearby over the boundaries of Bears Ears National Monument and Grand Staircase-Escalante, both of which President Trump slashed in order to increase drilling and mining opportunities.
Despite public pushback and some legal challenges, though, the frac sand mine seemed to be cruising toward approval as recently as October. It still needed an environmental impact assessment from the Bureau of Land Management, and the two water transfers needed approval from the state engineer. The project definitely wasn't a done deal, but in industry-friendly Utah, it had a good shot.
So it may have come as a surprise to a number of residents when Southern Red Sands announced at the beginning of January that it was abandoning the proposed project.
What happened? And are there any lessons that other communities fighting extraction threats can learn?
"Speak out, pull together like-minded neighbors, organize and don't give up," Hand told me after hearing the news. "But also, try to be nice."
Surprisingly, it's that last bit that may have made a big difference — along with a good hard look at the economics of the endeavor.
The Threats
Von Del Chamberlain is a white-haired, soft-spoken Kanab resident. Born in 1934, he spent his youth exploring the red rock and his career studying the stars. The astronomer and former director of Salt Lake City's Hansen (now Clark) Planetarium retired to his hometown 15 years ago and hoped to start a public observatory.
He realized that Kanab's prized dark-night skies would be threatened by a 24-7 mining operation. But that wasn't even his biggest concern with the project.
"The beauty here is the thing that will sustain this area economically for as far in the future as we can possibly see," he said.
Opponents like Chamberlain usually cited two big concerns: environmental impacts, particularly the threat to water resources, and the local economy. But in Kanab it's hard to separate the two.
"It doesn't matter what kind of an economy you want to develop here," said Hand. "Even if you have an industrial economy or an extractive economy — if you don't have water, you're out."
The water supply, which draws on underground aquifers, currently supports the town's tourist-driven economy, ranching, and the county's biggest employer — Best Friends Animal Society, known worldwide through the Dogtown TV series on the National Geographic Channel. The nonprofit owns a 3,700-acre sanctuary, the country's largest no-kill animal shelter, and would have been the mine's closest neighbor.
Best Friends, which employs 400 locals and draws 35,000 out-of-town visitors a year to its sanctuary, came to see the proposed mine as an existential threat. Their property relies on wells, seeps and springs that come from the same aquifer the project's two wells would tap.

Last July Kanab's city council approved a 50-year contract for 600 acre-feet a year of water rights for the project and Kane County Water Conservancy District, which oversees water servicing for the unincorporated areas of the county, agreed to provide an additional 600 acre-feet of water. That combined amount equals about 740 gallons per minute, although Southern Red Sands contended it would use only about a third of that.
Many local residents were shocked by the water-rights transfer. A 2016 water needs assessment found that Kane County Water Conservancy District's reliable supply would be in deficit by 2035. And the district's executive director, former state representative Mike Noel, has been a vocal advocate for a pricy proposed pipeline to send Lake Powell water to southern Utah communities, including near Kanab, under the premise that the region is already running short on water.
"We knew that it would damage our seeps and our springs, and we weren't sure yet the full impact besides some drawdown to our groundwater, but we were really concerned," Bart Battista, an environmental engineer responsible for facilities management at Best Friends' Kanab sanctuary, told me. "It boggles my mind that the city wasn't as concerned."
But documents unearthed by local radio station KUER showed that officials at nearby Zion National Park already were concerned that the project could reduce flows into the East Fork of the Virgin River, which flows through the park, by reducing the amount of water from underground seeps and springs that feed the river.
Wanting to learn more about how the project could affect the region's water, Best Friends commissioned a study from hydrogeologist Kenneth Kolm of Hydrologic Systems Analysis, a firm that's completed water studies for other Utah towns.
Kolm found that the mine posed the potential for decline in productivity to wells owned by both Best Friends and the city's water supply. The project could also decrease flows into nearby Kanab Creek and dry up perennial streams and springs, including one that feeds an area of habitat that's home to the Kanab ambersnail — currently federally protected as endangered.
The amount of water being withdrawn wasn't the only issue. The proposed project site and its sandy soil are also vitally important to local hydrology.
"The sand is the first ticket to collecting water," said Hand. It captures rain and holds it in place long enough for it to sink into the water table and not run off. But the sand is exactly what would be removed from the site, further threatening the region's water supply.
"I realized for the first time how small and vulnerable our watershed actually is," she added.
Southern Red Sands hoped to start digging on 640 acres of land around Red Knoll, an aptly name rise of coral-colored rock and sand. The area is managed as part of Utah's School and International Trust Lands Administration (SITLA), where state-owned property can be leased (often for resource extraction), with revenue being funneled to education.
The operation would have started by bulldozing all the trees, shrubs, grasses and forbs, then scraped up to 30 feet of the earth from the exposed surface. The sand would then be processed — washed with water and chemicals, then dried and sorted — in a facility with up to six 120-foot-tall silos. After that it would be loaded into trucks and hauled out.
A small fraction of the remaining sediment — mostly the fine silts and clays — would be put back on the land. But that change in geology could mean a big change for the aquifer. How big would depend on the scope of the project, though.
In addition to the SITLA land, Southern Red Sands had acquired placer claims — mineral exploration rights — for 12,000 surrounding acres managed by the BLM. And although the company said it planned to mine only 700,000 tons a year from the SITLA property, the facility would have had the capacity and water rights to accommodate much more.
"If they're building a plant with a capacity of 3 million tons a year, that's presumably because they expect to be able to produce that," Dean Baker, a Kanab resident and opponent of the project told me in December. "They may never do that, but you don't build extra capacity without the idea that you might use it."
The Resistance
Water issues are paramount in arid Utah, but the mine was likely to come with some other potential problems.
If Southern Red Sands did build out to end of their claims, they'd be within 10 miles of Zion National Park and workers at Best Friends would be looking over their fence line at the operation — not to mention potentially breathing its dust.
Mining, processing and trucking frac sand can release tiny particles of crystalline silica into the air. Inhaling those particles regularly can cause lung disease, including cancer and silicosis, a chronic disease that, like "black lung" for coal miners, can be deadly.

The facility would likely run with lights and noise 24-7, which could be detrimental to wildlife. And adding more diesel-spewing, slow-stopping big rigs hauling 50,000 pounds of sand down the town's one main road concerned residents, too.
With so much at risk, opponents employed a number of tactics to try to fight the mine.
Keep Kanab Unspoiled held community meetings. They invited Kolm, the geologist who did the independent study, to report his findings, and started an online petition to discourage the company from moving forward.
Best Friends — an established national nonprofit with considerably more financial resources — took the lead role in mounting legal challenges. The organization filed an appeal of a conditional use permit approved by the county and formally objected to the water transfers, which needed to be approved by the state engineer.
But during the fall, Best Friends decided to shift tactics. Lawsuits could just lead to years of legal battles, something beyond the organization's longstanding mission.
"We might alienate our donors and members," Battista explained. "The appeal of Best Friends crosses party boundaries — animal welfare is something everybody can support." Apparently environmental action is not.
They decided the best approach was to sit down and talk with the company and its backers.
Battista couldn't disclose details of the negotiations — which went on for months — but on Jan. 9 Best Friends and Southern Red Sands released a joint statement saying that the company "had decided not to pursue its business ventures in Kane County."
The members of Keep Kanab Unspoiled were elated by the news.
"It's so heartening how so many people from our community came together to amplify a voice that is seldom acknowledged by our elected representatives and institutions," Hand tells me. "I'm relieved that an area I love won't be sacrificed on the altar of fossil fuel consumption. I'm grateful that this threat to our travel and tourism economy is diminished."
It would be comforting to think that the driving force behind the decision boiled down to preserving the scenic beauty or the region's groundwater resources, but it's more likely it had to do with money.
"Economics played some role," Battista said. "The market for frac sand has changed and [Best Friends] had financial viability assessments of the project to show that the mine wouldn't be a good idea. Economically it just didn't make sense to any of us. I think that our studies corroborated that."
This was a main talking point of Keep Kanab Unspoiled, bolstered by research done by Baker, who also happens to be an economist and cofounder of the Center for Economic and Policy Research.
The frac sand industry — and the larger fracking industry — is volatile. The number of rigs drilling for oil tends to fall when prices get low. Rigs plunged with falling prices from 2014 to 2016 and last year saw record declines in rig numbers. In addition, fracking costs more than traditional drilling — and the industry has also been overspending to keep the fracking boom from going bust.
A research organization in Norway found that the amount of money being spent to drill for oil by 40 U.S. shale oil companies outpaced the money being made by selling that oil. That deficit cost companies almost $5 billion in just the first quarter of 2019, DeSmog reported in August.
It's a scenario that's happened before.
With oil prices now around $60 a barrel, the industry is hanging on. If prices dip much lower, it could be trouble. A decade into the fracking frenzy, investors are worried that the best spots have been drilled and many debts won't be paid.
There's even more uncertainty when it comes to producing and selling the sand. Companies used to rely almost exclusively on Midwest sand, but now more areas are getting in on the game.
The consequences of failures in the fracking business model are real.
Falling oil prices and a shifting market for frac sand recently took down Emerge Energy Services — owner of eight frac sand facilities in Wisconsin — which filed for bankruptcy last summer and left behind unsafe levels of arsenic and heavy metal contamination for the community to clean up.
That's a scenario that Baker worried could happen in Kanab. Southern Red Sands said their intended market was in Utah's Uintah Basin 350 miles north, but a new frac sand mine just opened in the basin. "It's almost inconceivable they'd be able to compete with them because the biggest cost with frac sand is the shipping," said Baker. "There are some operations in the San Juan basin [in New Mexico and Colorado] but it's not clear to me that they could beat those out either."
Even though economics played a role in halting the project, he believes community efforts were important, too.
"The fact they faced serious legal obstacles at every step in their path had to be a factor," he said. "It is a nice, and unfortunately rare, victory for the environment."
Best Friends worked to ensure the hard-earned victory wasn't short-lived, either. It also purchased Southern Red Sands' 12,000 acres of mineral rights.
"We want to make sure that no one else comes in here in two years if the market's better and tries to put in another sand mine, we just don't think that it's the right thing for this area," said Battista. "We want to make sure that in perpetuity, there's not a threat to the sanctuary."
As for Hand, she's now looking at the bigger picture. She saw the fight over frac sand in Kanab as a microcosm of the global fight over fossil fuels and climate change.
"While we can embrace a sense of triumph, it's likely to be brief," she said. "When it comes to protecting wild places and using our resources carefully, our work will never be done. The next development project is already bubbling. I do feel more hopeful for each success, but climate change marches on."

A key part of the United States' clean energy transition has started to take shape, but you may need to squint to see it. About 2,000 wind turbines could be built far offshore, in federal waters off the Atlantic Coast, in the next 10 years. And more are expected.
Threats to Birds
<p>One of the gravest threats facing birds is climate change, according to Audubon, which found that rising temperatures threaten <a href="https://www.audubon.org/2019climateissue" target="_blank" rel="noopener noreferrer">nearly two-thirds of North America's bird species</a>. That's why the impending development of offshore wind is a good thing, says Shilo Felton, a field manager in the organization's Clean Energy Initiative, but it also comes with dangers to birds that need to be better studied and mitigated.</p><p>The most obvious risk comes from birds colliding with spinning turbine blades. But offshore wind developments can also displace birds from foraging or roost sites, as well as migratory pathways.</p><p>Along the Atlantic Coast four imperiled species are of top concern to conservationists: the endangered piping plover, red knot, roseate tern and black-capped petrel, which is being considered for listing under the Endangered Species Act.</p><p>"Those four species are of utmost importance to make sure that we understand the impacts," says Felton. "But beyond that there are many species that are protected under the Migratory Bird Treaty Act and the Fish and Wildlife Conservation Act that could potentially see more impacts from offshore wind."</p><p>Northern gannets, for example, are at risk not just for collision but <a href="https://www.researchgate.net/publication/308703197_Possible_impacts_of_offshore_wind_farms_on_seabirds_a_pilot_study_in_Northern_Gannets_in_the_southern_North_Sea" target="_blank">habitat displacement</a>.</p>A northern gannet flying along Cape May, N.J. Ann Marie Morrison / CC BY-NC-ND 2.0
<p>"There's <a href="https://www.sciencedirect.com/science/article/abs/pii/S0006320716303196" target="_blank">some evidence</a> that they just won't use areas where turbines are, but that also excludes them from key foraging areas," says Felton. Researchers are still studying what this may mean for the birds. But a <a href="https://www.sciencedirect.com/science/article/pii/S0141113620305304" target="_blank">study</a> published in December 2020 conducted at Bass Rock, Scotland — home to the world's largest northern gannet colony — found that wind developments could reduce their growth rate, though not enough to cause a population decline.</p><p>Other birds, such as great cormorants and European shags, are <a href="https://www.sciencedirect.com/science/article/abs/pii/S0006320716303196" target="_blank">attracted to wind developments</a> and use the infrastructure to rest while opening up new foraging areas farther from shore.</p><p>"There's plenty of potential for a bird to use a wind farm and still to avoid the turbines themselves," says Felton.</p><p>Birds like pelicans, however, are less versatile in their movements and are at particular risk of collision because of their flight pattern, she says.</p><p>But how disruptive or dangerous offshore turbines will be along the East Coast isn't yet known.</p><p>Federal and state agencies, along with nongovernmental organizations, says Felton, have done good research to try to better understand those potential impacts. "But these are all theoretical, because we don't have a lot of offshore wind yet in the United States."</p>Threats to Ocean Life
<p>Birds aren't the only wildlife of concern. More development in ocean waters could affect a litany of marine species, some of which are already facing other pressures from overfishing, pollution, habitat destruction and climate change.</p><p>Scientists have found that marine mammals like whales and dolphins could be disturbed by the jarring sounds of construction, especially if pile driving is used to hammer the steel turbine platform into the seafloor.</p><p>The noises, though short-lived, could impede communication between animals, divert them from migration routes or cause them to seek less suitable areas for feeding or breeding. Research from Europe found that harbor porpoises, seals and dolphins may avoid development areas during construction. In most, but <a href="https://iopscience.iop.org/article/10.1088/1748-9326/7/4/045101" target="_blank">not all cases</a>, the animals were believed to have returned to the area following construction.</p><p>The biggest concern for conservation groups in the United States is the critically endangered North American right whale. There are fewer than 400 remaining, and the species' habitat overlaps with a number of planned wind development areas along the East Coast.</p><p>"Offshore wind is in no way the cause of the challenges the whales face, but it's going to be another pressure point," says John Rogers, senior energy analyst for the Union of Concerned Scientists.</p><p>Researchers aren't sure how right whales will respond to the noise from pile driving.</p><p>"But we are concerned, based on what we know about how whales react to other noise sources, that they may avoid [wind development] areas," says Kershaw.</p><p>And if that displacement causes them to miss out on important food resources, it could be dangerous for a species already on the brink.</p><p>There are a few other potential threats, too.</p><p>Ships associated with the development — more plentiful during construction — also pose a danger. In the past few years cargo ships, fishing boats and other vessels have caused half of all deaths of North Atlantic right whales.</p>A juvenile right whale breaches against the backdrop of a ship near the St. Johns River entrance. Florida Fish and Wildlife Conservation Commission / NOAA Research Permit #775-1600-10
<p>And after construction, the noise from the spinning turbines will be present in the water at low decibels. "We don't quite know how the great whales will react to those sounds," says Jeremy Firestone, the director of the Center for Research in Wind at the University of Delaware.</p><p>Other marine mammals may also perceive the noise, but at low decibels it's unlikely to be an impediment, <a href="http://www.int-res.com/abstracts/meps/v309/p279-295/" target="_blank">research has found</a>.</p><p>And it's possible that wind development could help some ocean life. Turbine foundations can attract fish and invertebrates for whom hard substrates create habitat complexity — known as the "reef effect," according to researchers from the University of Rhode Island's <a href="https://dosits.org/animals/effects-of-sound/anthropogenic-sources/wind-turbine/" target="_blank" rel="noopener noreferrer">Discovery of Sound in the Sea</a> program. Exclusion of commercial fishing nearby may also help shelter fish and protect marine mammals from entanglements in fishing gear.</p>Ensuring Safe Development
<p>Despite the potential dangers, researchers have gathered a few best practices to help diminish and possibly eliminate some risks.</p><p>When it comes to ship strikes, the easiest thing is to slow boats down, mandating a speed of <a href="https://biologicaldiversity.org/w/news/press-releases/vessel-speed-limits-sought-protect-endangered-north-atlantic-right-whales-2020-08-06/" target="_blank">10 knots</a> in wind development areas, and using visual and acoustic monitoring for whales.</p><p>Adjusting operations to reduce boat trips between the shore and the wind development will also help. A new series of service operating vessels can allow maintenance staff to spent multiple days onsite, says Kershaw, cutting down on boat traffic.</p><p>For construction noise concerns, developers can avoid pile driving during times of the year when whales are present. And, depending on the marine environment, developers could use "quiet foundations" that don't require pile driving. These include gravity-based or suction caisson platforms.</p><p>Floating turbines are also used in deep water, where they're effectively anchored in place — although that poses its own potential danger. "We have concerns that marine debris could potentially become entangled around the mooring cables of the floating arrays and pose a secondarily entanglement risk to some species," says Felton, who thinks more research should be conducted before those become operational in U.S. waters — a process that's already underway in Maine, where a <a href="https://composites.umaine.edu/2020/08/05/diamond-offshore-wind-rwe-renewables-join-the-university-of-maine-to-lead-development-of-maine-floating-offshore-wind-demonstration-project/" target="_blank" rel="noopener noreferrer">demonstration project is being built</a>.</p><p>If loud noises are unavoidable during construction, noise-reducing technologies such as bubble curtains can help dampen the sound. And scheduling adjacent projects to conduct similar work at the same time could limit the duration of disturbances.</p>The foundation installation of the off shore wind farm Sandbank using a bubble curtain. Vattenfall / Ulrich Wirrwa / CC BY-NC-ND 2.0
<p>Once turbines become operational, reducing the amount of light on wind platforms or using flashing lights could help deter some seabirds, NRDC <a href="https://www.nrdc.org/sites/default/files/harnessing-wind-advance-wind-power-offshore-ib.pdf" target="_blank" rel="noopener noreferrer">researchers reported</a>. And scientists are exploring using ultrasonic noises and ultraviolet lighting to keep bats away. "Feathering," or shutting down the turbine blades during key migration times, could also help prevent fatalities.</p><p>"We need to make sure that offshore wind is the best steward it can be of the marine ecosystem, because we want and expect it to be a significant part of the clean energy picture in some parts of the country," says Rogers. "We also have to recognize that we're going to learn by doing, and that some of these things we're going to figure out best once we have more turbines in the water."</p><p>That's why environmental groups say it's important to establish baseline information on species before projects begin, and then require developers to conduct monitoring during construction and for years after projects are operational.</p><p>Employing an "adaptive management framework" will ensure that developers can adjust their management practices as they go when new information becomes available, and that those best practices are incorporated into the requirements for future projects.</p>Putting Research Into Action
<p>Advancing these conversations at the federal level during the Trump administration, though, has been slow going.</p><p>"We didn't really have any productive discussions with the administration in the last four years," says Kershaw.</p><p>And when it comes to birds, Felton says the Bureau of Ocean Energy Management's recently completed "draft cumulative environmental impact statement" covering offshore wind developments had a lot of good environmental research, but little focus on birds.</p><p>"Part of that comes from the current administration's interpretation of the Migratory Bird Treaty Act," she says.</p><p>President Trump has been hostile to both wind energy <em>and</em> birds, <a href="https://www.nytimes.com/2021/01/05/climate/trump-migratory-bird-protections.html" target="_blank">and finished gutting the Migratory Bird Treaty Act</a> in his administration's the final days, removing penalties for companies whose operations kill migratory birds.</p><p>There's hope that the Biden administration will take a different approach. But where the federal government has been lacking lately, Kershaw says, they've seen states step up.</p><p>New York, for example, has established an <a href="https://www.nyetwg.com/" target="_blank" rel="noopener noreferrer">Environmental Technical Working Group</a> composed of stakeholders to advise on environmentally responsible development of offshore wind.</p><p>The group is led by the New York State Energy Research and Development Authority, but it isn't limited to the Empire State. It's regional in focus and includes representatives from wind developers with leases between Massachusetts and North Carolina; state agencies from Massachusetts to Virginia; federal agencies; and science-based environmental NGOs.</p><p>New York's latest solicitation for clean energy projects includes up to 2,500 megawatts of offshore wind and <a href="https://www.nyetwg.com/announcements" target="_blank" rel="noopener noreferrer">requires developers</a> to contribute at least $10,000 per megawatt for regional monitoring of fisheries and other wildlife.</p><p>Environmental groups have also worked directly with developers, including an agreement with Vineyard Wind — an 800-megawatt project off the Massachusetts coast that could be the first utility-scale wind development in federal waters — to help protect North Atlantic right whales.</p><p>The agreement includes no pile driving from Jan. 1 to April 30, ceasing activities at other times when whales are visually or acoustically identified in the area, speed restrictions on vessels, and the use of noise reduction technology, such as a bubble curtain during pile driving.</p><p>"The developers signed the agreement with us, and then they incorporated, most, if not all of those measures into the federal permitting documents," says Kershaw. "The developers really did a lot of bottom up work to make sure that they were being very protective of right whales."</p><p>Environmental groups are in talks with other developers on agreements too, but Felton wants to see best practices being mandated at the federal level.</p><p>"It's the sort of a role that should be being played by the federal government, and without that it makes the permitting and regulation process less stable and less transparent," she says." And that in turn slows down the build out of projects, which is also bad for birds because it doesn't help us address and mitigate for climate change."</p><p>Kershaw agrees there's a lot more work to be done, especially at the federal level, but thinks we're moving in the right direction.</p><p>"I think the work that's been done so far in the United States has really laid the groundwork for advancing this in the right way and in a way that's protective of species and the environment," she says. "At the same time, it's important that offshore wind does advance quickly. We really need it to help us combat the worst effects of climate change."</p><p><em><a href="https://therevelator.org/author/taralohan/" target="_blank" rel="noopener noreferrer">Tara Lohan</a> is deputy editor of The Revelator and has worked for more than a decade as a digital editor and environmental journalist focused on the intersections of energy, water and climate.

Cities Can Help Migrating Birds on Their Way By Planting More Trees and Turning Lights Off at Night
By Frank La Sorte and Kyle Horton
Millions of birds travel between their breeding and wintering grounds during spring and autumn migration, creating one of the greatest spectacles of the natural world. These journeys often span incredible distances. For example, the Blackpoll warbler, which weighs less than half an ounce, may travel up to 1,500 miles between its nesting grounds in Canada and its wintering grounds in the Caribbean and South America.

<p>For many species, these journeys take place at night, when skies typically are calmer and predators are less active. Scientists do not have a good understanding yet of how birds navigate effectively at night over long distances.</p><p><span></span>We study bird migration and how it is being affected by factors ranging from <a href="https://scholar.google.com/citations?user=S04C3UMAAAAJ&hl=en" target="_blank">climate change</a> to <a href="https://scholar.google.com/citations?user=pPk38-8AAAAJ&hl=en" target="_blank">artificial light at night</a>. In a recent study, we used millions of bird observations by citizen scientists to document the <a href="https://doi.org/10.1016/j.envpol.2020.116085" target="_blank">occurrence of migratory bird species in 333 U.S. cities</a> during the winter, spring, summer and autumn.</p>Blackpoll warbler. PJTurgeon / Wikipedia
<p>We used this information to determine how the number of migratory bird species varies based on each city's level of <a href="https://www.britannica.com/science/light-pollution" target="_blank" rel="noopener noreferrer">light pollution</a> – brightening of the night sky caused by artificial light sources, such as buildings and streetlights. We also explored how species numbers vary based on the quantity of tree canopy cover and impervious surface, such as concrete and asphalt, within each city. Our findings show that cities can help migrating birds by planting more trees and reducing light pollution, especially during spring and autumn migration.</p>Declining Bird Populations
<p>Urban areas contain numerous dangers for migratory birds. The biggest threat is the risk of <a href="https://doi.org/10.1650/CONDOR-13-090.1" target="_blank">colliding with buildings or communication towers</a>. Many migratory bird populations have <a href="http://dx.doi.org/10.1126/science.aaw1313" target="_blank">declined over the past 50 years</a>, and it is possible that light pollution from cities is contributing to these losses.</p><p>Scientists widely agree that light pollution can <a href="https://doi.org/10.1073/pnas.1708574114" target="_blank">severely disorient migratory birds</a> and make it hard for them to navigate. Studies have shown that birds will cluster around brightly lit structures, much like insects flying around a porch light at night. Cities are the <a href="https://doi.org/10.1002/fee.2029" target="_blank" rel="noopener noreferrer">primary source of light pollution for migratory birds</a>, and these species tend to be more abundant within cities <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/gcb.13792" target="_blank" rel="noopener noreferrer">during migration</a>, especially in <a href="https://doi.org/10.1016/j.landurbplan.2020.103892" target="_blank" rel="noopener noreferrer">city parks</a>.</p>Composite image of the continental U.S. at night from satellite photos.

The Power of Citizen Science
<p>It's not easy to observe and document bird migration, especially for species that migrate at night. The main challenge is that many of these species are very small, which limits scientists' ability to use electronic tracking devices.</p><p>With the growth of the internet and other information technologies, new data resources are becoming available that are making it possible to overcome some of these challenges. <a href="https://doi.org/10.1038/d41586-018-07106-5" target="_blank">Citizen science initiatives</a> in which volunteers use online portals to enter their observations of the natural world have become an important resource for researchers.</p><p>One such initiative, <a href="https://ebird.org/home" target="_blank" rel="noopener noreferrer">eBird</a>, allows bird-watchers around the globe to share their observations from any location and time. This has produced one of the <a href="https://doi.org/10.1111/ecog.04632" target="_blank" rel="noopener noreferrer">largest ecological citizen-science databases in the world</a>. To date, eBird contains over 922 million bird observations compiled by over 617,000 participants.</p>Light Pollution Both Attracts and Repels Migratory Birds
<p>Migratory bird species have evolved to use certain migration routes and types of habitat, such as forests, grasslands or marshes. While humans may enjoy seeing migratory birds appear in urban areas, it's generally not good for bird populations. In addition to the many hazards that exist in urban areas, cities typically lack the food resources and cover that birds need during migration or when raising their young. As scientists, we're concerned when we see evidence that migratory birds are being drawn away from their traditional migration routes and natural habitats.</p><p>Through our analysis of eBird data, we found that cities contained the greatest numbers of migratory bird species during spring and autumn migration. Higher levels of light pollution were associated with more species during migration – evidence that light pollution attracts migratory birds to cities across the U.S. This is cause for concern, as it shows that the influence of light pollution on migratory behavior is strong enough to increase the number of species that would normally be found in urban areas.</p><p>In contrast, we found that higher levels of light pollution were associated with fewer migratory bird species during the summer and winter. This is likely due to the scarcity of suitable habitat in cities, such as large forest patches, in combination with the adverse affects of light pollution on bird behavior and health. In addition, during these seasons, migratory birds are active only during the day and their populations are largely stationary, creating few opportunities for light pollution to attract them to urban areas.</p>Trees and Pavement
<p>We found that tree canopy cover was associated with more migratory bird species during spring migration and the summer. Trees provide important habitat for migratory birds during migration and the breeding season, so the presence of trees can have a strong effect on the number of migratory bird species that occur in cities.</p><p>Finally, we found that higher levels of impervious surface were associated with more migratory bird species during the winter. This result is somewhat surprising. It could be a product of the <a href="https://www.epa.gov/heatislands" target="_blank">urban heat island effect</a> – the fact that structures and paved surfaces in cities absorb and reemit more of the sun's heat than natural surfaces. Replacing vegetation with buildings, roads and parking lots can therefore make cities significantly warmer than surrounding lands. This effect could reduce cold stress on birds and increase food resources, such as insect populations, during the winter.</p><p>Our research adds to our understanding of how conditions in cities can both help and hurt migratory bird populations. We hope that our findings will inform urban planning initiatives and strategies to reduce the harmful effects of cities on migratory birds through such measures as <a href="https://www.arborday.org/programs/treecityusa/index.cfm" target="_blank" rel="noopener noreferrer">planting more trees</a> and initiating <a href="https://aeroecolab.com/uslights" target="_blank" rel="noopener noreferrer">lights-out programs</a>. Efforts to make it easier for migratory birds to complete their incredible journeys will help maintain their populations into the future.</p><p><em><span style="background-color: initial;"><a href="https://theconversation.com/profiles/frank-la-sorte-1191494" target="_blank">Frank La Sorte</a> is a r</span>esearch associate at the </em><em>Cornell Lab of Ornithology, Cornell University. <a href="https://theconversation.com/profiles/kyle-horton-1191498" target="_blank">Kyle Horton</a> is an assistant professor of Fish, Wildlife, and Conservation Biology at the Colorado State University.</em></p><p><em></em><em>Disclosure statement: Frank La Sorte receives funding from The Wolf Creek Charitable Foundation and the National Science Foundation (DBI-1939187).

Editor's note: This story is part of a nine-month investigation of drinking water contamination across the U.S. The series is supported by funding from the Park Foundation and Water Foundation. Read the launch story, "Thirsting for Solutions," here.
In late September 2020, officials in Wrangell, Alaska, warned residents who were elderly, pregnant or had health problems to avoid drinking the city's tap water — unless they could filter it on their own.
Unintended Consequences
<p>Chemists first discovered disinfection by-products in treated drinking water in the 1970s. The trihalomethanes they found, they determined, had resulted from the reaction of chlorine with natural organic matter. Since then, scientists have identified more than 700 additional disinfection by-products. "And those only represent a portion. We still don't know half of them," says Richardson, whose lab has identified hundreds of disinfection by-products. </p>What’s Regulated and What’s Not?
<p>The U.S. Environmental Protection Agency (EPA) currently regulates 11 disinfection by-products — including a handful of trihalomethanes (THM) and haloacetic acids (HAA). While these represent only a small fraction of all disinfection by-products, EPA aims to use their presence to indicate the presence of other disinfection by-products. "The general idea is if you control THMs and HAAs, you implicitly or by default control everything else as well," says Korshin.</p><p>EPA also requires drinking water facilities to use techniques to reduce the concentration of organic materials before applying disinfectants, and regulates the quantity of disinfectants that systems use. These rules ultimately can help control levels of disinfection by-products in drinking water.</p>Click the image for an interactive version of this chart on the Environmental Working Group website.
<p>Still, some scientists and advocates argue that current regulations do not go far enough to protect the public. Many question whether the government is regulating the right disinfection by-products, and if water systems are doing enough to reduce disinfection by-products. EPA is now seeking public input as it considers potential revisions to regulations, including the possibility of regulating additional by-products. The agency held a <a href="https://www.epa.gov/dwsixyearreview/potential-revisions-microbial-and-disinfection-byproducts-rules" target="_blank">two-day public meeting</a> in October 2020 and plans to hold additional public meetings throughout 2021.</p><p>When EPA set regulations on disinfection by-products between the 1970s and early 2000s, the agency, as well as the scientific community, was primarily focused on by-products of reactions between organics and chlorine — historically the most common drinking water disinfectant. But the science has become increasingly clear that these chlorinated chemicals represent a fraction of the by-product problem.</p><p>For example, bromide or iodide can get caught up in the reaction, too. This is common where seawater penetrates a drinking water source. By itself, bromide is innocuous, says Korshin. "But it is extremely [reactive] with organics," he says. "As bromide levels increase with normal treatment, then concentrations of brominated disinfection by-products will increase quite rapidly."</p><p><a href="https://pubmed.ncbi.nlm.nih.gov/15487777/" target="_blank">Emerging</a> <a href="https://pubs.acs.org/doi/10.1021/acs.est.7b05440" target="_blank" rel="noopener noreferrer">data</a> indicate that brominated and iodinated by-products are potentially more harmful than the regulated by-products.</p><p>Almost half of the U.S. population lives within 50 miles of either the Atlantic or Pacific coasts, where saltwater intrusion can be a problem for drinking water supplies. "In the U.S., the rule of thumb is the closer to the sea, the more bromide you have," says Korshin, noting there are also places where bromide naturally leaches out from the soil. Still, some coastal areas tend to be spared. For example, the city of Seattle's water comes from the mountains, never making contact with seawater and tending to pick up minimal organic matter.</p><p>Hazardous disinfection by-products can also be an issue with desalination for drinking water. "As <a href="https://ensia.com/features/can-saltwater-quench-our-growing-thirst/" target="_blank" rel="noopener noreferrer">desalination</a> practices become more economical, then the issue of controlling bromide becomes quite important," adds Korshin.</p>Other Hot Spots
<p>Coastal areas represent just one type of hot spot for disinfection by-products. Agricultural regions tend to send organic matter — such as fertilizer and animal waste — into waterways. Areas with warmer climates generally have higher levels of natural organic matter. And nearly any urban area can be prone to stormwater runoff or combined sewer overflows, which can contain rainwater as well as untreated human waste, industrial wastewater, hazardous materials and organic debris. These events are especially common along the East Coast, notes Sydney Evans, a science analyst with the nonprofit Environmental Working Group (EWG, a collaborator on <a href="https://ensia.com/ensia-collections/troubled-waters/" target="_blank">this reporting project</a>).</p><p>The only drinking water sources that might be altogether free of disinfection by-products, suggests Richardson, are private wells that are not treated with disinfectants. She used to drink water from her own well. "It was always cold, coming from great depth through clay and granite," she says. "It was fabulous."</p><p>Today, Richardson gets her water from a city system that uses chloramine.</p>Toxic Treadmill
<p>Most community water systems in the U.S. use chlorine for disinfection in their treatment plant. Because disinfectants are needed to prevent bacteria growth as the water travels to the homes at the ends of the distribution lines, sometimes a second round of disinfection is also added in the pipes.</p><p>Here, systems usually opt for either chlorine or chloramine. "Chloramination is more long-lasting and does not form as many disinfection by-products through the system," says Steve Via, director of federal relations at the American Water Works Association. "Some studies show that chloramination may be more protective against organisms that inhabit biofilms such as Legionella."</p>Alternative Approaches
<p>When he moved to the U.S. from Germany, Prasse says he immediately noticed the bad taste of the water. "You can taste the chlorine here. That's not the case in Germany," he says.</p><p>In his home country, water systems use chlorine — if at all — at lower concentrations and at the very end of treatment. In the Netherlands, <a href="https://dwes.copernicus.org/articles/2/1/2009/dwes-2-1-2009.pdf" target="_blank">chlorine isn't used at all</a> as the risks are considered to outweigh the benefits, says Prasse. He notes the challenge in making a convincing connection between exposure to low concentrations of disinfection by-products and health effects, such as cancer, that can occur decades later. In contrast, exposure to a pathogen can make someone sick very quickly.</p><p>But many countries in Europe have not waited for proof and have taken a precautionary approach to reduce potential risk. The emphasis there is on alternative approaches for primary disinfection such as ozone or <a href="https://www.pbs.org/wgbh/nova/article/eco-friendly-way-disinfect-water-using-light/" target="_blank" rel="noopener noreferrer">ultraviolet light</a>. Reverse osmosis is among the "high-end" options, used to remove organic and inorganics from the water. While expensive, says Prasse, the method of forcing water through a semipermeable membrane is growing in popularity for systems that want to reuse wastewater for drinking water purposes.</p><p>Remucal notes that some treatment technologies may be good at removing a particular type of contaminant while being ineffective at removing another. "We need to think about the whole soup when we think about treatment," she says. What's more, Remucal explains, the mixture of contaminants may impact the body differently than any one chemical on its own. </p><p>Richardson's preferred treatment method is filtering the water with granulated activated carbon, followed by a low dose of chlorine.</p><p>Granulated activated carbon is essentially the same stuff that's in a household filter. (EWG recommends that consumers use a <a href="https://www.ewg.org/tapwater/reviewed-disinfection-byproducts.php#:~:text=EWG%20recommends%20using%20a%20home,as%20trihalomethanes%20and%20haloacetic%20acids." target="_blank" rel="noopener noreferrer">countertop carbon filter</a> to reduce levels of disinfection by-products.) While such a filter "would remove disinfection by-products after they're formed, in the plant they remove precursors before they form by-products," explains Richardson. She coauthored a <a href="https://pubs.acs.org/doi/10.1021/acs.est.9b00023" target="_blank" rel="noopener noreferrer">2019 paper</a> that concluded the treatment method is effective in reducing a wide range of regulated and unregulated disinfection by-products.</p><br>Greater Cincinnati Water Works installed a granulated activated carbon system in 1992, and is still one of relatively few full-scale plants that uses the technology. Courtesy of Greater Cincinnati Water Works.
<p>Despite the technology and its benefits being known for decades, relatively few full-scale plants use granulated active carbon. They often cite its high cost, Richardson says. "They say that, but the city of Cincinnati [Ohio] has not gone bankrupt using it," she says. "So, I'm not buying that argument anymore."</p><p>Greater Cincinnati Water Works installed a granulated activated carbon system in 1992. On a video call in December, Jeff Swertfeger, the superintendent of Greater Cincinnati Water Works, poured grains of what looks like black sand out of a glass tube and into his hand. It was actually crushed coal that has been baked in a furnace. Under a microscope, each grain looks like a sponge, said Swertfeger. When water passes over the carbon grains, he explained, open tunnels and pores provide extensive surface area to absorb contaminants.</p><p>While the granulated activated carbon initially was installed to address chemical spills and other industrial contamination concerns in the Ohio River, Cincinnati's main drinking water source, Swertfeger notes that the substance has turned out to "remove a lot of other stuff, too," including <a href="https://ensia.com/features/drinking-water-contamination-pfas-health/" target="_blank" rel="noopener noreferrer">PFAS</a> and disinfection by-product precursors.</p><p>"We use about one-third the amount of chlorine as we did before. It smells and tastes a lot better," he says. "The use of granulated activated carbon has resulted in lower disinfection by-products across the board."</p><p>Richardson is optimistic about being able to reduce risks from disinfection by-products in the future. "If we're smart, we can still kill those pathogens and lower our chemical disinfection by-product exposure at the same time," she says.</p><p><em>Reposted with permission from </em><em><a href="https://ensia.com/features/drinking-water-disinfection-byproducts-pathogens/" target="_blank">Ensia</a>. </em><a href="https://www.ecowatch.com/r/entryeditor/2649953730#/" target="_self"></a></p>At a time of impending global food scarcity, cell-based meats and seafood have been heralded as the future of food.
