Wells that people drill to access groundwater supply nearly half the water used for irrigated agriculture in the U.S. and provide over 100 million Americans with drinking water. Unfortunately, pervasive pumping is causing groundwater levels to decline in some areas, including much of California's San Joaquin Valley and Kansas' High Plains.
We are a water resources engineer with training in water law and a water scientist and large-data analyst. In a recent study, we mapped the locations and depths of wells in 40 countries around the world and found that millions of wells could run dry if groundwater levels decline by only a few meters. While solutions vary from place to place, we believe that what's most important for protecting wells from running dry is managing groundwater sustainably – especially in nations like the U.S. that use a lot of it.

Groundwater Use Today
Humans have been digging wells for water for thousands of years. Examples include 7,400-year-old wells in the Czech Republic and Germany, 8,000-year-old wells in the eastern Mediterranean, and 10,000-year-old wells in Cyprus. Today wells supply 40% of water used for irrigation worldwide and provide billions of people with drinking water.
Groundwater flows through tiny spaces within sediments and their underlying bedrock. At some points, called discharge areas, groundwater rises to the surface, moving into lakes, rivers and streams. At other points, known as recharge areas, water percolates deep into the ground, either through precipitation or leakage from rivers, lakes and streams.
Groundwater can remain underground for days to millennia, depending on how deep it sinks, how readily it moves through rock around it and how fast humans pump it to the surface.
Groundwater declines can have many undesirable consequences. Land surfaces sink as underground clay layers are compacted. Seawater intrusion can contaminate groundwater reserves and make them too salty to use without energy-intensive treatment. River water can leak down to underground aquifers, leaving less water available at the surface.
Groundwater depletion can also cause wells to run dry when the top surface of the groundwater – known as the water table – drops so far that the well isn't deep enough to reach it, leaving the well literally high and dry. Yet until recently, little was known about how vulnerable global wells are to running dry because of declining groundwater levels.
There is no global database of wells, so over six years we compiled 134 unique well construction databases spanning 40 different countries. In total, we analyzed nearly 39 million well construction records, including each well's location, the reason it was constructed and its depth.
Our results show that wells are vital to human livelihoods – and recording well depths helped us see how vulnerable wells are to running dry.
Millions of Wells at Risk
Our analysis led to two main findings. First, up to 20% of wells around the world extend no more than 16 feet (5 meters) below the water table. That means these wells will run dry if groundwater levels decline by just a few feet.
Second, we found that newer wells are not being dug significantly deeper than older wells in some places where groundwater levels are declining. In some areas, such as eastern New Mexico, newer wells are not drilled deeper than older wells because the deeper rock layers are impermeable and contain saline water. New wells are at least as likely to run dry as older wells in these areas.
Wells are already going dry in some locations, including parts of the U.S. West. In previous studies we estimated that as many as 1 in 30 wells were running dry in the western U.S., and as many as 1 in 5 in some areas in the southern portion of California's Central Valley.
Households already are running out of well water in the Central Valley and southeastern Arizona. Beyond the Southwest, wells have been running dry in states as diverse as Maine, Illinois and Oregon.
What to Do When the Well Gives Out
How can households adapt when their well runs dry? Here are five strategies, all of which have drawbacks.
– Dig a new, deeper well. This is an option only if fresh groundwater exists at deeper depths. In many aquifers deeper groundwater tends to be more saline than shallower groundwater, so deeper drilling is no more than a stopgap solution. And since new wells are expensive, this approach favors wealthier groundwater users and raises equity concerns.
– Sell the property. This is often considered if constructing a new well is unaffordable. Drilling a new household well in the U.S. Southwest can cost tens of thousands of dollars. But selling a property that lacks access to a reliable and convenient water supply can be challenging.

– Divert or haul water from alternative sources, such as nearby rivers or lakes. This approach is feasible only if surface water resources are not already reserved for other users or too far away. Even if nearby surface waters are available, treating their quality to make them safe to drink can be harder than treating well water.
– Reduce water use to slow or stop groundwater level declines. This could mean switching to crops that are less water-intensive, or adopting irrigation systems that reduce water losses. Such approaches may reduce farmers' profits or require upfront investments in new technologies.
– Limit or abandon activities that require lots of water, such as irrigation. This strategy can be challenging if irrigated land provides higher crop yields than unirrigated land. Recent research suggests that some land in the central U.S. is not suitable for unirrigated "dryland" farming.
Households and communities can take proactive steps to protect wells from running dry. For example, one of us is working closely with Rebecca Nelson of Melbourne Law School in Australia to map groundwater withdrawal permitting – the process of seeking permission to withdraw groundwater – across the U.S. West.
State and local agencies can distribute groundwater permits in ways that help stabilize falling groundwater levels over the long run, or in ways that prioritize certain water users. Enacting and enforcing policies designed to limit groundwater depletion can help protect wells from running dry. While it can be difficult to limit use of a resource as essential as water, we believe that in most cases, simply drilling deeper is not a sustainable path forward.

Why You Should Choose an Organic Mattress
Traditionally, mattresses contain trace amounts of chemicals known as volatile organic compounds (VOCs) that act as flame retardants and coatings on plastic components. While the popular view is that these VOCs are found in too low of concentrations to be concerning, a 2019 study published in Environmental Science and Technology indicates that body heat may transform them into toxic vapors that you breathe in through the night.
That's a reason for concern, as according to the US Environmental Protection Agency, the potential health effects of VOC exposure include headaches and eye, nose, and throat irritation. In extreme cases, they may trigger cancer cell development or organ damage.

Funded by the California legislature in 2018, the new report involved a literature review, scientific symposium for experts, peer review process, and public comment period. Its conclusions about the behavioral effects of food dyes are grounded in the results of 27 clinical trials in children performed on four continents over the last 45 years, as well as animal studies and research into the mechanisms through which dyes exert their behavioral effects.
Food dyes in products such as breakfast cereals, juice and soft drinks, frozen dairy desserts, candies, and icings were linked to adverse neurobehavioral outcomes in children including inattentiveness, hyperactivity, and restlessness. Animal studies also revealed effects on activity, memory, and learning.
The report is the most rigorous assessment of the behavioral effects of food dyes ever conducted, said Lisa Lefferts, a senior scientist with the Washington, D.C.-based nonprofit Center for Science in the Public Interest. (Editor's note: Lefferts previously worked as an editor at EHN).
Lefferts has been tracking the issue for years and through the Center published her own report on the link between synthetic food dyes and behavioral problems in children in 2016. In it she called for the U.S. Food and Drug Administration (FDA) to either revoke approvals for all food dyes or institute a federal labeling rule.
The European Union enacted such a law in 2010 that requires most dyed foods to bear a label warning consumers that food colorings "may have an adverse effect on activity and attention in children." In response, many food manufacturers reformulated their products for the European market to avoid the dyes, and thus the label.
But many left the dyes in their products for the U.S. market, where awareness of the issue has remained low, said Lefferts. "In our experience, most consumers have no idea that something that is allowed in the food supply by the FDA could trigger adverse behaviors," she told EHN.
A California State Senate bill introduced in February and backed by the new report would require a similar warning label on foods sold in the state. But it was abruptly withdrawn from the Senate Health Committee on April 28, the day of its scheduled hearing, by sponsor Senator Bob Wieckowski (D-Fremont).
In a press release, Wieckowski said he pulled the bill "to take additional time to brief other senators and make sure they understand the science in the OEHHA report" given that it had been published only 12 days earlier. The bill, which Lefferts said she sees as a wedge for widespread reformulation of dyed foods in the U.S, is now slated to be heard in January 2022.
Widespread Food Dye Exposure

The FDA last formally reviewed the issue in 2011, when it concluded that a causal link between children's consumption of synthetic color additives and behavioral effects had not been established. At the time the agency also commissioned an exposure assessment of all seven color additives approved for use in food in the U.S.: FD&C Blue No. 1, Blue No. 2, Green No. 3, Red No. 3, Red No. 40, Yellow No. 5, and Yellow No. 6.
The results of this study, later presented in 2014, revealed that between 2007 and 2010, some dyes were consumed on an almost daily basis by up to 98 percent of 2-to-5-year-olds, 95 percent of teenage boys aged 13-18, and 94 percent of the entire U.S. population aged 2 and up.
"Exposure in children affects attention and behavior across the whole spectrum of the population, and it's a widely distributed exposure," Mark Miller, a public health medical officer with OEHHA and one of 13 authors of the report, told EHN. "Overall it means that the impact is subject to being fairly large."
Mechanistic studies reviewed by Miller and the report's other authors reveal that food dyes may impact behavior through a variety of pathways including neurotransmitters, hormones, and oxidative stress. More research is needed on how dyes are absorbed, distributed, and metabolized in the body, they note.
An FDA spokesperson said that the agency had received and was reviewing the report. "The FDA will continue to engage in the scientific and regulatory review of color additives to evaluate their potential impact on various populations, including children, and act when necessary to ensure that the products marketed to consumers are safe and properly labeled," the statement read.
"Parents who wish to limit synthetic color additives in their children's diet may check the food ingredient list on labels, where they are required to be listed."

"The feeling that people have towards spiders is not unique," says Marco Isaia, an arachnologist and associate professor at the University of Turin in Italy. "Nightmares, anxieties and fears are very frequent reactions in 'normal' people," he concedes.
Perhaps that's why spiders remain under-represented across the world's endangered-species conservation plans. Average people don't think much about them, relatively few scientists study them, and conservation groups and governments don't act enough to protect them.
That's a major gap in species-protection efforts — one that has wide repercussions. "Efforts in conservation of spiders are particularly meaningful for nature conservation," Isaia points out. Spiders, he says, have enormous ecological value as food for birds and other animals. They're also important to people, both as predators of pest species and as inspiration for medicines and engineering.
And yet they remain neglected.
How bad is the problem? A new paper by Isaia and 18 other experts digs into the conservation status of Europe's 4,154 known spider species and finds that only a few have any protection at the national level. Most have never even been adequately assessed or studied in detail, so we don't know much about their extinction risk or their ecological needs.
Italy, for example, is home to more than 1,700 spider species, but fewer than 450 have had their conservation status assessed and only two have any legal protection in that country.
Greece, meanwhile, has nearly 1,300 spider species within its borders, but scientists have only assessed the conservation needs of 32 of them. None are legally protected.

Researchers found the same results — or lack thereof — throughout Europe.
"What surprised us most while assembling the data was the extremely poor level of knowledge about the conservation status, extinction risk and factors threatening the survival of European spider species, despite Europe being one of the most studied regions of the world in terms of biodiversity," says Filippo Milano, the study's lead author and a Ph.D. student in Isaia's research team. "And even when the conservation status of the species was provided, information was often incomplete or out-of-date, resulting in assessments based on poor quality information and high levels of subjectivity."
It's not just individual European nations; the problem is continent-wide. The researchers say just one spider — the endangered Gibraltar funnel-web spider (Macrothele calpeiana) from the Southern Iberian Peninsula — is protected at the European level by the Bern Convention, an international treaty about habitat and species conservation on the continent and some African nations, and European Union Habitats Directive.

And of course, this is not unique to Europe; other countries and continents fail to protect arachnids, and for similar reasons.
"Spiders are understudied, underappreciated and under attack by both the climate crisis and humans affecting our environment," says spider expert and science communicator Sebastian Alejandro Echeverri, who was not affiliated with the study. "These are one of the most diverse groups of animals that we don't really think about on a day-to-day basis. There's like 48,000-plus species, but my experience is that most people don't really have a sense of how many are in their area. In the United States, for example, we have just 12 spiders on the endangered species list out of the thousands of species recorded here."
This lack of information or protection at the national level affects international efforts. At the time the research was conducted the IUCN Red List, which includes conservation status assessments for 134,400 species around the world, covered just 301 spider species, eight of which are from Europe. That number has since increased — to all of 318 species from the order Araneae. (And perhaps tellingly, it's worth noting that the Gibraltar funnel-web spider has not currently been assessed for the IUCN Red List.)

The Red List does not grant protections to any species, but it's often used by governments and conservation groups to seek protections on the national or international level.
That dearth of IUCN data seems likely to change, since one of the paper's authors is also the chair of the IUCN Spider and Scorpion Specialist Group, but they have a monumental task ahead of them.
The Web of Borders
As we see with so many other wide-ranging species, a transnational border is often not a spider's friend. The paper identifies several examples of species protected in one country but not its neighbor, despite being found in both places. According to the paper only 17 spider species are protected by conservation legislation in two or more European countries.
"Animals aren't limited by our political lines on a map," notes Echeverri. "You can protect something here, but if that animal's habitat extends past your border and the people next door don't know about it or don't protect its habitat in the same way, it could still be pushed toward extinction even though you're doing your best."
At the same time, cross-border protection can also create problems if legislation is based on out-of-date scientific data. The Gibraltar funnel-web spider — the one species that's listed on the Bern Convention and the EU Habitats Directive — has "protection against all forms of disturbance, capture, keeping, deliberate killing, and damage or destruction of breeding or resting sites," according to the paper. That's essential in its native habitat, but at the same time it's now rapidly spreading through the commercial olive-tree trade and has been spotted in at least four countries outside its range. "As a matter of fact, it seems that the unique spider protected at the European level is considered an alien species in many countries," says Milano.
How Do We Fix This?
Echeverri calls the study "an important call to action." In particular, he points out how it compares different spider assessment and conservation approaches in each country. "This gives people in the IUCN and lawmakers a tool to say, 'hey, this system seems to be working really well, let's take what we can from it that will work great in our country.'"
Isaia notes that they hope this paper spins out a wide-reaching web. "We hope to stimulate environmental government agencies, stakeholders and decision-makers to include spiders in effective conservation strategies and fostering processes that may contribute to the conservation of threatened spider species," he says. Examples, he says, would include "promoting risk assessment procedures for spider species, or including threatened spider species in planning protected areas and biodiversity action plans."

But moving forward will require a lot of effort — not to mention some money.
"There's not a lot of funding for naturalists to go out and survey these animals," says Echeverri. "It's this ongoing crisis within science. You don't know a lot about the species, so you don't know who's there. You don't know how many are there. You don't know how they're doing or what habitats they're in, and we need to make our conservation plans based on scientific data. If that data doesn't exist, even if there is a desire to do something for these animals, we can't plan anything because we don't have the fundamentals."
The researchers hope others will take up their mantle to understand and protect spiders. "Highlighting general patterns and identifying the main strengths and weaknesses in biodiversity conservation across Europe is an appropriate starting point to plan achievable solutions focusing on the local context," says Milano. "The same model may be adopted to other geographic regions and may certainly apply to other taxonomic groups."
And maybe, along the way, their work can help inspire people who fear spiders to look at them in a different light — or even to help look for them, like the Map the Spider project that asks citizen scientists to upload locations of the complex webs woven by elusive purse-web spiders.
Who knows, that might even inspire a new generation of arachnologists — a field of scientists who are currently in short supply.
"Focusing on spiders has been a very important choice in my career," Isaia says. "There are those who, like me, see spiders as miracles of the natural evolution. You may study their web, their venom, their bizarre behaviors, the interactions between different species, their role as predators, their amazing taxonomical and functional diversity, their key role in the maintaining ecosystem equilibrium. You may also use them as sources of inspiration in architecture and visual arts. Aren't these good reasons to find them attractive?"

According to preliminary deforestation alert data released Friday by Brazil's national space research institute INPE, deforestation in the Brazilian portion of the Amazon amounted to 581 square kilometers in April, a 43% increase over April 2020 and the highest April tally since 2018.

However, by INPE's count, deforestation is still pacing behind last year's rate: When measured since the start of the "deforestation year" — which begins August 1 — 4,640 square kilometers of rainforest has been lost, a decline of 15% for the nine-month period.
But the trend reported by INPE is not matched by data from Imazon, a Brazilian organization that independently monitors deforestation. Imazon's data shows eight straight months of rising deforestation: Through the end of March, Imazon puts forest loss as 33% above last year's level.
The discrepancies between the systems can generally be chalked up to the different methodologies they use. And both systems generate "preliminary data" which is used primarily for tracking where deforestation is occurring on a near-real-time basis, rather than comprehensively documenting forest loss.
The annual assessment, which uses higher resolution imagery and measures loss between August 1 and July 31, is considered the official baseline. Using that approach, deforestation for the 2019-2020 year amounted to 11,088 square kilometers, the highest on record since 2008.
Deforestation has accelerated sharply since Bolsonaro took office January 1, 2019. Based on deforestation alert data, forest clearing during his administration to date is about 98% higher than the same period of time under his predecessor, and 206% higher than Dilma Rousseff's first 16 months in office.

Cousteau's eldest grandson, Fabien, was born to continue his grandfather's legacy. Fabien learned to scuba dive on his fourth birthday and joined his famous grandfather on his legendary ships, the Calypso and Alcyone. Now, the younger Cousteau is following in his grandfather's footsteps and bubbles, taking the ocean exploration and conservation he grew up with and giving it a modern, technology-driven, community-focused revamp.
EcoWatch recently joined Fabien and members of his team at the Fabien Cousteau Ocean Learning Center (FCOLC) on marine debris cleanup dives in the Florida Keys. Funded and organized by the "Goal: Clean Seas Florida Keys" program, the program is a partnership between the Florida Keys National Marine Sanctuary, the National Marine Sanctuary Foundation and Blue Star Diving Operators, who are trained in the best practices for marine debris removal. The community-led collaboration grew out of the devastating aftermath from Hurricane Irma in Sept. 2017, which displaced approximately 154,000 lobster traps, many of which were dragged across sensitive ocean habitats for up to 15 miles. In its first year alone, trained operators helped remove more than 10,000 pounds of marine debris from sanctuary waters. Now in its third year, the program teamed up with locals from the Florida Keys and the FCOLC team to spread ocean awareness and remove traps from local coral reefs.

EW: Why oceans? What's the appeal?
FC: When one has experienced the ocean world, it's impossible to turn your back on it. It's a privilege and a responsibility to share the adventure and the passion with other... And, I love it. I'm addicted to oceans.
EW: What is your favorite thing about the oceans?
FC: The sense of being, the sense of community. The sense of tranquility that it gives. The fact that it gives us everything that we require as well as the things that make us — the intangibles that give us our humanity.
EW: How do you remember your grandfather?
FC: I had the luck of spending the first 30 years of my life with my grandfather around. For years, maybe the first decade and a half, I just saw him as my grandfather. We would see him in family gatherings, whether in the field or at home. He would tell us stories. He would be how I imagine most grandparents are — very interested in their grandchildren and spending time with them. It wasn't until we were in a Japanese restaurant in New York City one day and people kept coming up to our table to interrupt our family time asking for him to sign things that I realized our grandfather wasn't just for us. We were sharing him with the world. And that's when I realized — very naïve of me — what an iconic public figure he was, especially for the ocean world.

EW: Why should others care about the oceans?
FC: Without the oceans, we're a brown rock in space like all the others. The oceans set our planet apart and allow us to survive and thrive. We share the planet with all kinds of sentient beings. To envision a better future, we have to live in symbiosis with all of them.
EW: What's the current state of the planet?
FC: We're facing a terminal illness if we don't do something. It's not trite to say that... As a species, we are directly responsible for our very own future. We're the only species that can do that, that can determine its own future. And that's the most fundamentally important thing everyone needs to understand.

EW: You're not just taking this sitting down. Tell us about the Fabien Cousteau Ocean Learning Center and what you're trying to do.
FC: The mission is to educate, empower and engage. It's based on a quote my grandpa told me as a kid: People protect what they love, they love what they understand, and they understand what they're taught. The only way we're getting out of this is if we fill the proverbial bucket together one drop at a time — one action at a time. We're all responsible for what we see today, so the solution isn't from one source like myself or an individual doing their best, it's all of us pitching in.
EW: What does that look like for you and FCOLC?
FC: We all need to do our part and invest in ocean protection, conservation and science. Our Nicaragua program is a great example of all three.
(Editorial Note: Per FCLOC Nicaragua Program Manager Pamela Fletcher and Operations Manager Martín Molina Castellnon, the Nicaragua program addressed three phases, and involves mangrove restoration and sea turtle conservation.)
- Phase 1 involved the local and indigenous communities in mangrove restoration. As a critical blue carbon sink, mangroves sequester more carbon than any other plant or tree, Fabien noted.
- Phase 2 evolved into the current sea turtle conservation project. Nesting beaches of several species are patrolled, and nests are protected from poachers. Eggs are then relocated to guarded hatcheries, and the community and local university students are empowered to create a future in conservation and science.
- Phase 3, which has already started, will grow to include the empowerment of local women and girls. In transitioning the conservation program management to them, they take on the responsibility of protecting sea turtles and spreading awareness to their local communities. This builds the foundation for girls to envision a future in conservation and STEM. Girls and women also learn the tools for making conservation a viable business that can sustain them and their families.
Pamela Fletcher: Our biggest success is the shift we're seeing in how [the girls helping with the sea turtle program] value themselves in the community and value protecting these amazing species.
Martín Molina Castellnon: In Nicaragua, these things are all managed by men, and we transitioned them to be women. It's taken off like a rocket. One little girl who's only eight years old has been in the program for two years, and she collects plastics, brings them to school and tells her friends about what's happening in the oceans. She's our future pioneer.
FC: She's a trailblazer.
MMC: Women empowerment has really changed their lives. And, it's made a big difference in the community.

EW: Now, tell me about Proteus.
(Editorial Note: Proteus is a conceptual underwater research station that Fabien hopes will change how underwater research is tackled. It will be the world's largest and most advanced underwater habitat located 60 feet below the surface in Curaçao. The goal is for it to be completely modular and customizable, run by renewable energy and filled with cutting-edge technology.)
FC: This is a very large project. Proteus will be like the International Space Station of the sea. That was by design, and it's meant to give people that image because a lot of science will be coming out of it. Educational components and broadcasting will be for the social good, for the benefit of humanity and the planet. Underwater habitats are the missing tool in underwater exploration. It doesn't take away from ships, ROVs, probes, scuba, etc. — it's something that fills a big gap we currently have.
EW: What gives you hope?
FC: What's exciting to me is that we know so little about the oceans. We've explored only five percent. That's a huge opportunity. But, we also need to understand we're having a huge impact on our oceans, too. We're treating it as a garbage can, but really, it's a closed-loop system that we're banking on. Now, that bank account is going bankrupt, so we need to fill it back up.
EW: Any advice to those reading?
FC: Protect the ocean as if your life depended on it — because it does.

Small water systems serving housing developments, mobile home parks, businesses and small towns have been particularly hard-hit. Most didn't realize their water was unsafe until weeks to months after the fire.
The problem starts when wildfire smoke gets into the system or plastic in water systems heats up. Heating can cause plastics to release harmful chemicals, like benzene, which can contaminate drinking water and permeate the system.
As an environmental engineer, I and my colleagues work with communities recovering from wildfires and other natural disasters. Last year, at least seven water systems were found to be contaminated, suggesting drinking water contamination may be a more widespread problem than people realize.
Our new study identifies critical issues that households and businesses should consider after a wildfire. Failing to address them can harm people's health – mental, physical and financial.
Wildfires Make Drinking Water Unsafe
When wildfires damage water distribution pipes, wells and the plumbing in homes and other buildings, they can create immediate health risks. A building's plumbing can become contaminated by smoke getting sucked into water systems, by heat damaging plastic pipes – or contamination penetrating into the plumbing and leaching out slowly over time.
Since 2017, multiple fires have rendered drinking water systems unsafe, including the Echo Mountain, Lionshead and Almeda fires in Oregon, and the CZU Lightning Complex, Camp and Tubbs fires in California. Thousands of private wells have been affected too.
Being exposed to contaminated water can cause immediate harm, such as headaches, nausea, dizziness and vomiting. Short-term exposure to 26 parts per billion or more of benzene, a carcinogen, may cause a decrease in white blood cells that protect the body from infectious disease. Multiple fires have caused drinking water to exceed this level. A variety of other chemicals can exceed safe drinking water exposure limits too in the absence of benzene.
Households Are Not Being Adequately Warned
In a survey of 233 households affected by water contamination, we found people reported high levels of anxiety and stress linked to the water problems. Nearly half had installed in-home water treatment because of uncertainty about the water. Eighty-five percent had looked for other water sources, such as bottled water.
In some cases, we found that advice from government agencies placed households at greater risk of harm. It has sometimes left people exposed to chemicals, caused them to needlessly spend money and given them a false sense of security. Certified in-home water treatment devices, for example, are tested only to bring down 15 parts per billion of benzene to less than 5 parts per billion, the federal standard. These devices are not tested to treat hazardous waste-scale contaminated water that's been found after wildfires.
Following the 2020 CZU Lightning Complex Fire near Santa Cruz, California, a local health department correctly warned private well owners not to use their water and to test it, but a nearby damaged water system and the state did not warn 17,000 people against bathing in the contaminated water. It was only after test results proved the water had been unsafe all along that the system owner and state advised against bathing in it.
In Oregon, some damaged systems encouraged people to boil their drinking water, later finding that the water had benzene in it.
After the 2018 Camp Fire that devastated Paradise, California, the local health department correctly warned the entire county not to use or try to treat the drinking water, which had contamination above EPA's hazardous waste limit. But one water system and the state encouraged 13,000 people to try to treat it themselves.

In all of these cases, the U.S. Environmental Protection Agency chose not to compel water utilities to explicitly notify customers about the water contamination and its risk.
Communities have received other bad information:
- Commercial labs and government officials recommended flushing faucets for 5 to 15 minutes before collecting a water sample, thereby dumping out the contaminated plumbing water meant for testing.
- Homeowners were led to believe a single cold water sample at the kitchen sink would determine if the hot water system and property service line was contaminated. It cannot.
- People were led to believe that benzene water testing would determine if any other chemicals were present above safe limits. This is not possible.
What to look for after a nearby fire
Signs of potential contamination after a nearby wildfire could be loss of water pressure, discolored water, heat damage to water systems inside and outside buildings, and broken and leaking pipes, valves and hydrants.
Drinking water should be assumed to be chemically unsafe until proven otherwise.
Once a system is contaminated, cleanup can take months. The water system will have to be flushed and tested regularly to track down contamination. Health departments should also issue guidance on how to test private wells and plumbing.
When testing plumbing, include the property service line as well as the hot and cold water lines. Before collecting a water sample, the water must sit long enough in the plumbing so contamination can be found – 72 hours was the Tubbs Fire and Camp Fire standard. Tests should look for more than benzene.

Who can help?
Many of the critical public health risks identified in our new study can be addressed by public health departments with financial support from state and local agencies.
Public health departments often have experience responding to water problems, such as legionella outbreaks, and can provide technical advice about both chemical exposures, building plumbing and private drinking water wells.

Lauren Rathmell and Mohamed Hage cofounded Lufa in 2009. The company has four urban gardens in the Canadian city, all in rooftop greenhouses. Lufa's most recent sits on top of a former warehouse and measures more than 15,000m2 – larger than the other three greenhouses combined. Its main crops are tomatoes and aubergines, producing more than 11,000kg of food per week. It is, the company says, the largest rooftop greenhouse in the world.
An Ambitious Goal
Rathmell says the new greenhouse will accelerate Lufa's mission to grow food where people live and help it to meet an "ever-growing demand for fresh, local, and responsible foods".
The company – which says it's not trying to replace local farms and food makers, acknowledging that not everything can be grown on rooftops – follows what it calls 'responsible agriculture' practices. These include capturing and recirculating rainwater, energy-saving glass panels, and an absence of synthetic pesticides. Any waste is composted and reused, and food is sold directly to customers on the day it is harvested. Lufa also has a fleet of electric vehicles to make those deliveries.
"Our objective at Lufa is to get to the point where we're feeding everyone in the city," Hage said in an interview in Fortune. Lufa's fifth greenhouse is due to open later in 2021.
At the moment, Lufa grows food for around 2% of the city's population. While that might sound like a modest proportion, interest in urban agriculture is on the rise. Presently, agriculture in urban areas tends to be more common in developing countries. But the UN Food and Agriculture Organization (FAO) favors an increase in urban agriculture, saying it can have "important benefits for food security."

Urban agriculture has been taking off in other parts of the world in recent years, too – from shipping containers in Brooklyn, New York City, to allotments in unused spaces in Brussels, Belgium.
And at 14,000 m2, there's Nature Urbaine in Paris – which claims to be the world's largest urban rooftop farm. Nature Urbaine rents out growing space to Parisians who want to grow their own crops. Tenant farmers pay around $450 per year per 1m2 sized plot. They get a welcome pack with everything they need to start growing, as well as regular access to the Nature Urbine gardening team who are on hand to offer advice and support.
Lufa's first greenhouse was opened in 2011, in Montreal's Ahuntsic-Cartierville borough, to grow herbs, microgreens, cucumbers and peppers. Two more were added in 2013 and 2017, with the fourth joining last year. It sits on top of a former Sears warehouse in the Saint-Laurent area of the city.
In addition to its own produce, Lufa also sells a selection of other locally made or grown food, including bread, cheese and drinks to its customers. Rising demand for its service, in the wake of the pandemic, led to the company hiring an additional 200 people, and partnering with 35 new farmers and food makers.
