Across Farm Country, Fertilizer Pollution Impacts Not Just Health, but Water Costs, Too

News Feed
Wednesday, May 1, 2024

When Jeff Broberg and his wife, Erica, moved to their 170-acre bean and grain farm in Winona, Minnesota in 1986, their well water measured at 8.6 ppm for nitrates. These nitrogen-based compounds, common in agricultural runoff, are linked to multiple cancers and health issues for those exposed. Each year, the measurement in their water kept creeping up. In the late 1990s, Broberg decided it was time to source from elsewhere. He began hauling eight one-gallon jugs and two five-gallon jugs from his friend Mike’s house. That was his drinking water for the week. Six years ago, Broberg said, he was “getting too old to haul that water in the middle of the winter.” So, he installed his own reverse-osmosis water filtration system. The measurement of nitrates in his well has now reached up to 22 ppm. Post-filtration, the levels are almost nonexistent. Broberg, a retired geologist, has committed what he calls his “encore career” to advocating for clean water in Minnesota. He only leases out around 40 percent of his tillable land and has retired much of the rest due to groundwater pollution concerns. Almost one year ago, a group he co-founded, the Minnesota Well Owners Organization, joined other groups to petition the U.S. Environmental Protection Agency (EPA) to address groundwater contamination in southeast Minnesota. The EPA agreed, stating that “further action is needed to protect public health” and requested that the state create a plan for testing, education and supplying alternative drinking water to those most affected. Advocates in Wisconsin filed a petition, too. Last month, 13 separate groups in Iowa did the same. This advocacy comes in light of increased regional attention on nitrate pollution and its health effects. In Nebraska, researchers have connected high birth defect rates with exposure to water contaminated with nitrates. In Wisconsin, experts warn that exposure to nitrates can increase the risk of colon cancer. Access to clean water, as defined by the United Nations, is a human right. And yet many currently don’t have that right, even in a country where potable water is taken for granted. What’s more, the cost of clean water falls more heavily on less populated areas, where fewer residents shoulder the bill. A report by the Union of Concerned Scientists concluded that the cost for rural Iowa residents—who often live in areas with smaller, more expensive water systems—could be as much as $4,960 more per person per year to filter out nitrates from their water than their counterparts in cities like Des Moines. Nitrates are affecting water utilities from California to D.C., and the reason comes down to one major source: Agricultural runoff. Where The Trouble Begins: ‘A Leaky System’ The root of water-quality issues in the Midwest starts with its cropland drainage system, a network of underground, cylindrical tiles that drain excess water and nutrients from the land and funnel it downstream. Those tiles, which were first installed in the mid-1800s and have now largely been replaced with plastic pipes, ultimately allowed farmers to grow crops on land that was once too wet to farm. Lee Tesdell is the fifth generation to own his family’s 80-acre farm in Polk County, Iowa. Tesdell explained that when his European ancestors settled in the Midwest, they plowed the prairie and switched from deeply rooted perennial plants to shallow-rooted annual crops like wheat, oats, and corn instead. “Then we had more exposed soil and less water infiltration because the roots weren’t as deep,” he said. “The annual crops and drainage tile started to create this leaky system.” This “leaky system” refers to what is not absorbed by the crops on the field, most dangerously, in this case, fertilizer. “It’s a leaky system because it’s not in sync,” said Iowa water quality expert Chris Jones, author of The Swine Republic book (and blog).  “And farmers know they’re going to lose some fertilizer. As a consequence, they apply extra as insurance.” Fertilizer as Poison The U.S. is the top corn-producing country in the world, with states like Iowa, Illinois, Nebraska, and Minnesota supplying 32 percent of corn globally. Corn produces lower yields if it is nitrogen deficient, so farmers apply nitrogen-heavy fertilizer to the crop. In fact, they must use fertilizer in order to qualify for crop insurance. The ammonia in the fertilizer oxidizes existing nitrogen in the soil, turning it into highly water-soluble nitrates that aren’t fully absorbed by the corn. Those nitrates leak into aquifers. In 1960, farmers used approximately 3 million tons of nitrogen fertilizer a year. In 2021, that number was closer to 19 million. Farmers can use a nitrogen calculator to determine how much nitrogen they need—but nearly 70 percent of farmers use more than the recommended amount. “Other people also have an American dream, and they want to be able to turn on their faucet and have clean water, or know that if they put their baby in a bath, they’re not going to end up in the hospital with major organs shutting down because they have been poisoned.” As Jones explains in his blog, even with “insurance” fertilizer use, yields can often turn out the same: “What happened to that extra 56 pounds of nitrogen that you bought? Well, some might’ve ended up sequestered in the soil, but a lot of it ran off into lakes and streams or leached down into the aquifer (hmm, do you reckon that’s why the neighbor’s well is contaminated?), and some off-gassed to the atmosphere as nitrous oxide, a substance that has 300 times more warming potential than carbon dioxide.” Commercial fertilizer is just one contributor to high nitrate levels in groundwater. The other main factor, manure, is also increasing as CAFOs become more prevalent. Nancy Utesch and her husband, Lynn, live on 150 acres of land in Kewaunee County, Wisconsin, where they rotationally graze beef cattle. In 2004, a family nearby became very ill from E. coli poisoning in their water. “I was really upset that this had happened in our county,” she said. “A lot of the support was for the polluting farmer, and you know, farming is right there with the American flag and grandma’s apple pie.” Utesch worries that the current system of industrialized agriculture has created a world where people living closest to the polluters do not have access to clean water themselves, and are afraid to speak out against the actions of their neighbors. “Other people also have an American dream, and they want to be able to turn on their faucet and have clean water, or know that if they put their baby in a bath, that they’re not going to end up in the hospital with major organs shutting down because they have been poisoned,” she said. “If they clean a scrape because their grandchild fell down in the driveway, they could be hurting them if they use the water from the tap.” The Plight of the Small Town In June 2022, fertilizer runoff pushed Des Moines Water Works, the municipal agency charged with overseeing drinking water, to restart operations of their nitrate removal system—one of the largest in the world—at a cost of up to $16,000 per day. Des Moines finances its removal system from its roughly 600,000 ratepayers. “Financially, Des Moines can spread out needed treatment over many thousands of customers, whereas a small town can’t do that,” Jones said. “If you have a small town of 1,000 people, your well gets contaminated, and you need a $2 million treatment plan to clean up the water, that’s a burden.” “Financially, Des Moines can spread out needed treatment over many thousands of customers, whereas a small town can’t do that.” While cities like Des Moines are willing to pay the cost to remove nitrates, other small communities will have a tougher time doing so. And once their aquifer is contaminated, “it doesn’t go away for a long time, in some cases, thousands of years,” Jones said. Utica, Minnesota, which has fewer than 300 residents, has two deep wells, both measuring at unsafe levels for nitrates. “[Residents are] scared to death,” Broberg, who lives in a neighboring town, said. “The city has investigated water treatment expenses at around $3 million for reverse osmosis, and they only last 10 years. A town of 85 households can’t amortize that debt by themselves.” The town has applied for a grant from the state and is waiting to hear back. Another nearby town, Lewiston, dug a new, deeper well to solve their nitrate problem. “They went down there, and the water was contaminated with radium. It’s radioactive,” Broberg said. “So they kept their nitrate-contaminated well and their radium-contaminated well and blended the water so that it doesn’t exceed the health risk limit for either nitrates or radium.” However, as Chris Rogers reported in the Winona Post, that plan didn’t quite work. Thus, Lewiston dug another well at a cost of $904,580, and is now sourcing all of their water from that new well. That well is now testing trace amounts of nitrates and has less radium than before. Many rural residents also rely on private, personal well systems, which aren’t regulated for contaminants, to source their water. Forty million people rely on well water nationwide. “Public water systems have these maximum contaminant levels that are set by the EPA. There are rules and regulations that they have to follow, but private wells aren’t covered by the Safe Drinking Water Act,” said Stacy Woods, research director of the food and environment program at the Union of Concerned Scientists. “It’s really on individual well owners to decide whether to test their wells and what contaminants to test their wells for, and these tests can be really expensive.” Broberg and his group are working to extend the protection of the Safe Drinking Water Act to well water. In southeast Minnesota, the EPA agreed to the plan, though the path forward is still uncertain as funding packages move through the legislature. “I’ve spoken with people who simply don’t want to test their well water because they can’t afford to do much about it if they find out that their nitrate levels are unsafe.” Without these protections in place, or intervention at the pollution source, rural residents often find the responsibility of clean water falling on them. “I’ve spoken with people who simply don’t want to test their well water because they can’t afford to do much about it if they find out that their nitrate levels are unsafe,” Food and Water Watch Legal Director Tarah Heinzen said. “They are basically powerless to protect their drinking water resources from sources of pollution that aren’t being adequately regulated by the state.” The solution, according to Woods, “is to protect the drinking water sources from that pollution in the first place.” Conservation on the Farm One way to do this is by using less fertilizer on the field. Another is to introduce on-the-field and edge-of-field conservation practices, like Tesdell is doing on his Iowa family farm. Tesdell’s farm is not the typical Iowa farm, which averages 359 acres. Tesdell’s is 80. He does, however, rent 50 acres to a neighbor who grows corn and soybeans, like most Iowa farmers. Where Tesdell’s farm differs is how he deals with excess nitrate. In 2012, Tesdell, who has always been drawn to conservation, became interested in adding cover cropping to his fields. Through his research, he came across other conservation practices such as wood chip bioreactors. He installed his first bioreactor that same year. “There’s a chemical and biological reaction between the wood chips and the nitrate in the tile water,” Tesdell said. “Much of the nitrate then is turned into nitrogen gas, which is a harmless gas. We don’t take out 100 percent of the nitrate, but we take out a good percentage.” According to Iowa State University, a typical bioreactor costs around $10,000 to design and install. Tesdell paid for his bioreactor partly out of pocket, but also acquired funding from the Iowa Soybean Association. For his saturated buffer, an edge-of-field practice that redirects excess nitrates through vegetation, Tesdell received funding from the USDA’s Environmental Quality Incentives Program (EQIP). To install the saturated buffer, Tesdell needed his neighbor to agree. “We put that one on a tile that actually comes from my neighbor’s farm. Because the creek is going through my farm, it’s a more direct route to come off a hill [on] his farm,” he said. “Neighbors need to work together.” Roughly 80 percent of the farmland in Iowa is owned by offsite landlords, who rent it out to farmers. Tesdell cites this as  a roadblock to conservation practices. “If the landowner doesn’t care, why would an operator care? They want to pull in with their 24-row planter, plant their corn, come in with the 12-row corn head in October and harvest, then truck it off to the ethanol plant,” he said. “I don’t blame them.” Iowa currently has a “Nutrient Reduction Strategy” plan, which outlines voluntary efforts farmers can take to reduce their pollution. There is no active legislation that limits how much fertilizer farmers use on their cropland. Heinzen, of Food and Water Watch, explained that agricultural pollution is largely unregulated, with the exception of concentrated animals feeding operations (CAFOs).  “In fact, even most CAFOs are completely unregulated, because EPA has completely failed to implement Congress’s intent to regulate this industry, which we’re suing them over,” she said, referring to a new brief filed by multiple advocacy groups in February aimed at upgrading CAFO pollution regulation. Even Des Moines Waterworks, with its state-of-the-art nitrate removal facility, is calling for change. “We cannot keep treating water quality only at the receiving end,” spokesperson Melissa Walker said. “There needs to be a plan for every acre of farmland in Iowa and how its nutrients will be managed, as well as every animal and its manure.” “You’re either going to have to change your practices, change your farming, or you’re going to have the accept the risk of preventable disease.” Some communities have sued for damages related to nitrate-contaminated groundwater. In Millsboro, Delaware, residents received a payout but still have contaminated water. In Boardman, Oregon, five residents are suing the Port of Morrow and multiple farms and CAFOs due to their well-water testing “at more than four times the safe limit established by the U.S. EPA,” Alex Baumhardt reported in the Oregon Capital Chronicle. A few weeks ago, 1,500 tons of liquid nitrogen were spilled into an Iowa river. No living fish were found nearby. Today, polluted water flows downstream into the Gulf of Mexico, where it causes “dead zones” stripped of marine life. “You’re either going to have to change your practices, change your farming, or you’re going to have the accept the risk of preventable disease,” Broberg said. “And you need to put that equation in your family budget. If you’re going to get bladder cancer, diabetes, birth defects, juvenile cancers—what are those going to cost?” When asked why protecting water is so important, Tesdell paused and looked away. His voice cracked with emotion. “It’s for the grandkids.” The post Across Farm Country, Fertilizer Pollution Impacts Not Just Health, but Water Costs, Too appeared first on Civil Eats.

Eating less sugar would be great for the planet as well as our health

"Globally, sugar intake has quadrupled over the last 60 years . . ."

Sugar addiction is on the rise. Globally, sugar intake has quadrupled over the last 60 years, and it now makes up around 8% of all our calories. This sounds like sugar's keeping us fed, but added sugars are actually empty calories – they are bereft of any nutrients like vitamins or fibers. The result is massive health costs, with sugars linked to obesity around the world. Some estimates suggest that half the global population could be obese by 2035. A limited 20% reduction in sugar is estimated to save US$10.3 billion (£8.1 billion) of health costs in the US alone. Yet, sugar's impacts go far beyond just health and money. There are also many environmental problems from growing the sugar, like habitat and biodiversity loss and water pollution from fertilizers and mills. But overall, sugar hasn't received a lot of attention from the scientific community despite being the largest cultivated crop by mass on the planet. In a recent article, we evaluated sugar's environmental impacts and explored avenues for reducing sugar in the diet to recommended levels either through reducing production or using the saved sugar in environmentally beneficial ways. By phasing out sugar, we could spare land that could be rewilded and stock up on carbon. This is especially important in biodiverse tropical regions where sugar production is concentrated such as Brazil and India. But a different, more politically palatable option might be redirecting sugar away from diets to other environmentally-beneficial uses such as bioplastics or biofuels. Our study shows that the biggest opportunity is using sugar to feed microbes that make protein. Using saved sugar for this microbial protein could produce enough plant-based, protein-rich food products to regularly feed 521 million people. And if this replaced animal protein it could also have huge emission and water benefits. We estimate that if this protein replaced chicken, it could reduce emissions by almost 250 million tons, and we'd see even bigger savings for replacing beef (for reference, the UK's national fossil fuel emissions are around 300 million tons). Given sugar has a far lower climate impact than meat, this makes a lot of sense. Another alternative is to use the redirected sugar to produce bioplastics, which would replace around 20% of the total market for polyethelyne, one of the most common forms of plastic and used to produce anything from packaging to pipes. Or to produce biofuels, producing around 198 million barrels of ethanol for transportation. Brazil already produces around 85% of the world's ethanol and they produce it from sugar, but instead of having to grow more sugar for ethanol we could redirect the sugar from diets instead. This estimation is based on a world where we reduce dietary sugar to the maximum in dietary recommendations (5% of daily calories). The benefits would be even larger if we reduced sugar consumption even further. Supply chain challenges This sounds like a big win-win: cut sugar to reduce obesity and help the environment. But these changes present a huge challenge in a sugar supply chain spanning more than 100 countries and the millions of people that depend on sugar's income. National policies like sugar taxes are vital, but having international coordination is also important in such a sprawling supply chain. Sustainable agriculture is being discussed at the UN's climate summit, Cop29, in Azerbaijan this week. Sustainable sugar production should factor into these global talks given the many environmental problems and opportunities from changing the way we grow and consume sugar. We also suggest that groups of countries could come together in sugar transition partnerships between producers and consumers that encourage a diversion of sugar away from peoples' diets to more beneficial uses. This could be coordinated by the World Health Organization which has called for a reduction in sugar consumption. Some of the money to fund these efforts could even come from part of the health savings in national budgets. We can't hope to transition the way we produce and eat sugar overnight. But by exploring other uses of sugar, we can highlight what environmental benefits we are missing out on and help policymakers map a resource-efficient path forward to the industry while improving public health.   Don't have time to read about climate change as much as you'd like?

CDC issues warning of hot tub-caused Legionnaires’ Disease The US Centers for Disease Control and Prevention (CDC) recently released a health warning following an outbreak of Legionnaires’ Disease among passengers who had been on cruises.  As reported by Travel News, the CDC found that a number of cases of Legionnaires’ Disease were connected by an unnamed cruise ship, between November 2022 and April 2024 of this year. Private outdoor hot tubs on the balconies of two cruise ships were pinpointed as the source of the bacteria for multiple infections between the period, as stated in a report last month from the CDC. “Epidemiologic, environmental and laboratory evidence suggests that private balcony hot tubs were the likely source of exposure in two outbreaks of Legionnaires’ disease among cruise ship passengers,” the CDC said in the report.   “These devices are subject to less stringent operating requirements than public hot tubs, and operating protocols were insufficient to prevent Legionella growth.” they added. What is Legionnaires’ Disease? According to Cleveland Clinic: “Legionnaires’ disease is a serious type of pneumonia you get when Legionella bacteria infect your lungs. Symptoms include high fever, cough, diarrhea and confusion. You can get Legionnaires’ disease from water or cooling systems in large buildings, like hospitals or hotels.” Legionella is found naturally in lakes, streams and soil, but it can also contaminate drinking water and air systems, especially in large buildings. You can breathe small droplets of water directly into your lungs, or water in your mouth can get into your lungs accidentally You also have an increased risk of getting Legionnaires’ disease if you: Are older than 50. Smoke or used to smoke cigarettes. Have a weakened immune system. Certain medical conditions (like HIV, diabetes, cancer and kidney or liver disease) and medications can compromise your immune system. Have a long-term respiratory illness, such as chronic obstructive pulmonary disease (COPD) or emphysema. Live in a long-term care facility. Have stayed in a hospital recently. Have had surgery requiring anesthesia recently. Have received an organ transplant recently. The post CDC warns cruise passengers of hot tub disease outbreak appeared first on SA People.

TCEQ to hold public permit renewal meeting for Houston concrete plant with past compliance issues

The Torres Brothers Ready Mix plant has “a history of violations,” according to the Harris County Attorney’s Office. Air Alliance Houston is urging community members to attend the Monday night meeting.

Katie Watkins/Houston Public MediaMany concrete batch plant facilities have permits to operate 24 hours a day. Residents will often complain of the bright lights and noise at night.The Texas Commission on Environmental Quality will hear public comments on the permit renewal of a concrete plant with a history of water and air pollution issues. "They have a history of noncompliance," said Crystal Ngo, environmental justice outreach coordinator with Air Alliance Houston. Over the course of three visits from 2021 through 2024, Harris County Pollution Control Services documented "significant violations" of the state's clean air and water laws at the Torres Brothers Ready Mix plant in South Houston. The Harris County Attorney's Office argued the plant is "unable to comply" with the conditions of its permit and state laws. The county is involved in ongoing litigation with the company and seeks more than $1 million in relief. Torres Brothers did not immediately respond to a request for comment. The plant is one of five in the area. TCEQ doesn't consider the cumulative impact of separate facilities in its permitting process. Instead, it examines the compliance of individual sites. Ngo pointed to public health concerns related to air, water, noise and particulate matter pollution, as well as noise and light nuisances. "With so many concrete batch planets within environmental justice communities, predominantly communities of color, this higher exposure is just disproportionate to more affluent neighborhoods in Houston," Ngo said. The meeting is scheduled for 7 p.m. Monday, Nov. 18, at the Hiram Clarke Multi-Service Center.

Standing Desks Are Better for Your Health—but Still Not Enough

Two recent studies offer some of the most nuanced evidence yet about the potential benefits and risks of working on your feet.

Without question, inactivity is bad for us. Prolonged sitting is consistently linked to higher risks of cardiovascular disease and death. The obvious response to this frightful fate is to not sit—move. Even a few moments of exercise can have benefits, studies suggest. But in our modern times, sitting is hard to avoid, especially at the office. This has led to a range of strategies to get ourselves up, including the rise of standing desks. If you have to be tethered to a desk, at least you can do it while on your feet, the thinking goes.However, studies on whether standing desks are beneficial have been sparse and sometimes inconclusive. Furthermore, prolonged standing can have its own risks, and data on work-related sitting has also been mixed. While the final verdict on standing desks is still unclear, two studies out this year offer some of the most nuanced evidence yet about the potential benefits and risks of working on your feet.Take a SeatScience NewsletterYour weekly roundup of the best stories on health care, the climate crisis, new scientific discoveries, and more. Delivered on Wednesdays.For years, studies have pointed to standing desks improving markers for cardiovascular and metabolic health, such as lipid levels, insulin resistance, and arterial flow-mediated dilation (the ability of arteries to widen in response to increased blood flow). But it's unclear how significant those improvements are to averting bad health outcomes, such as heart attacks. One 2018 analysis suggested the benefits might be minor.And there are fair reasons to be skeptical about standing desks. For one, standing—like sitting—is not moving. If a lack of movement and exercise is the root problem, standing still wouldn't be a solution.Yet, while sitting and standing can arguably be combined into the single category of “stationary,” some researchers have argued that not all sitting is the same. In a 2018 position paper published in the Journal of Occupational and Environmental Medicine, two health experts argued that the link between poor health and sitting could come down to the specific populations being examined and “the special contribution” of “sitting time at home, for example, the ‘couch potato effect.’”The two researchers—emeritus professors David Rempel, formerly at the University of California, San Francisco, and Niklas Krause, formerly of UCLA—pointed to several studies looking specifically at occupational sitting time and poor health outcomes, which have arrived at mixed results. For instance, a 2013 analysis did not find a link between sitting at work and cardiovascular disease. Though the study did suggest a link to mortality, the link was only among women. There was also a 2015 study on about 36,500 workers in Japan who were followed for an average of 10 years. That study found that there was no link between mortality and sitting time among salaried workers, professionals, and people who worked at home businesses. However, there was a link between mortality and sitting among people who worked in farming, forestry, and fishing industries.Still, despite some murkiness in the specifics, more recent studies continue to turn up a link between total prolonged sitting—wherever that sitting occurs—and poor health outcomes, particularly cardiovascular disease. This has kept up interest in standing desks in offices, where people don't always have the luxury of frequent movement breaks. And this, in turn, has kept researchers on their toes to try to answer whether there is any benefit to standing desks.

Breathing Dirty Air Might Raise Eczema Risks

By Ernie Mundell HealthDay ReporterFRIDAY, Nov. 15, 2024 (HealthDay News) -- Cases of the autoimmune skin condition eczema appear to rise in areas most plagued by air pollution, new research shows.Since data has long shown that rates of eczema -- clinically known as atopic dermatitis -- increase along with industrialization, dirty air might be a connecting link, according to the team from Yale University.“Showing that individuals in the United States who are exposed to particulate matter [in air] are more likely to have eczema deepens our understanding of the important health implications of ambient air pollution," wrote researchers led by Yale School of Medicine investigator Gloria Chen.Her team published its findings Nov. 13 in the journal PLOS ONE.According to the National Eczema Association, over 31 million Americans have the skin disorder, "a group of inflammatory skin conditions that cause itchiness, dry skin, rashes, scaly patches, blisters and skin infections."The exact causes of eczema aren't clear, but it's thought to originate in an an overactive immune system that responds to certain environmental triggers.Could air pollution be one of those triggers?To find out, the Yale team looked at data on almost 287,000 Americans, about 12,700 of who (4.4%) had an eczema diagnosis.They compared local eczema rates against levels of air pollution in zip codes across the United States.Chen's team focused especially on what's known as "fine particulate matter" -- microscopic bits of pollution that can get deep into the lungs with each breath.The result: With every increase of 10 micrograms of fine particulate matter per square meter of air that was recorded in a zip code, residents' odds for eczema doubled, the Yale group found.That risk assessment held even after the researchers factored in other possible triggers, including smoking.The study couldn't prove a cause and effect relationship, only associations. But the team pointed to similar findings from studies conducted in places as varied as Australia, Germany and Taiwan.Besides playing a role in the development of eczema, "individuals [already diagnosed] with eczema may be at elevated risk for disease exacerbation or acute flares" when local air quality declines, the researchers wrote.On very smoggy days, "patients may be advised to stay indoors, filter indoor air or cover exposed skin outdoors," Chen and colleagues added.SOURCE: PLOS ONE, Nov. 14, 2024Copyright © 2024 HealthDay.
