Drought can hit almost anywhere: How 5 cities that nearly ran dry got water use under control
In 2024, the U.S. Northeast faced severe drought, prompting lessons on water management from cities like Cape Town and São Paulo. Proactive conservation and planning can mitigate future crises.

Water scarcity is often viewed as an issue for the arid American West, but the U.S. Northeast’s experience in 2024 shows how severe droughts can occur in just about any part of the country.
Cities in the Northeast experienced record-breaking drought conditions in the second half of 2024 after a hot, dry summer in many areas. Wildfires broke out in several states that rarely see them.
By December, much of the region was experiencing moderate to severe drought. Residents in New York City and Boston were asked to reduce their water use, while Philadelphia faced risk to its water supply due to saltwater coming up the Delaware River.
Before the drought, many people in the region weren’t prepared for water shortages or even paying much attention to their water use.
As global temperatures rise, cities throughout the U.S. are more likely to experience hotter, drier conditions like this. Those conditions increase evaporation, drying out vegetation and soil and lowering groundwater tables.
The Northeast drought was easing in much of the region in early 2025, but communities across the U.S. should take note of what happened. They can learn from the experiences of cities that have had to confront major water supply crises – such as Cape Town, South Africa; São Paulo, Brazil; Melbourne, Australia; Las Vegas; and New Orleans – and start planning now to avoid the worst impacts of future droughts.
Lessons from cities that have seen the worst
Our new analysis of these five cities’ experiences provides lessons on how to avoid a water supply crisis or minimize the effects through proactive policies and planning.
Many cities have had to confront major water supply crises in recent years. Perhaps the most well-known example is Cape Town’s “Day Zero.”
After three years of persistent drought in the region, Cape Town officials in fall 2017 began a countdown to Day Zero – the point at which water supplies would likely run so low that water would be turned off in neighborhoods and residents would need to fetch a daily allocation of water at public distribution points. Initially it was forecast to occur in April 2018.
Water rates were raised, and some households installed flow restrictors, which would automatically limit the amount of water that could be used. Public awareness and conservation efforts cut water consumption in half, allowing the city to push back its estimate for when Day Zero would arrive. And when the rains finally came in summer 2018, Day Zero was canceled.
A second example is São Paulo, which similarly experienced a severe drought between 2013 and 2015. The city’s reservoirs were reduced to just 5% of their capacity, and the water utility reduced the pressure in the water system to limit water use by residents.
Water pricing adjustments were used to penalize high water users and reward water conservation, and a citywide campaign sought to increase awareness and encourage conservation. As in Cape Town, the crisis ended with heavy rains in 2016. Significant investments have since been made in upgrading the city’s water distribution infrastructure, preventing leaks and bringing water to the city from other river basins.
Planning ahead can reduce the harm
The experiences of Cape Town and São Paulo – and the other cities in our study – show how water supply crises can affect communities.
When major changes are made to reduce water consumption, they can affect people’s daily lives and pocketbooks. Rapidly designed conservation efforts can have harmful effects on poor and vulnerable communities that may have fewer alternatives in the event of restrictions or shutoffs or lack the ability to pay higher prices for water, forcing tough choices for households between water and other necessities.
Planning ahead allows for more thoughtful policy design.
For example, Las Vegas has been grappling with drought conditions for the past two decades. During that time, the region implemented water-conservation policies that focus on incentivizing and even requiring reduced water consumption.
Since 2023, the Las Vegas Valley Water District has implemented water rates that encourage conservation and can vary with the availability of water supplies during droughts. In its first year alone, the policy saved 3 billion gallons of water and generated US$31 million in fees that can be used by programs to detect and repair leaks, among other conservation efforts. A state law now requires businesses and homeowner associations in the Las Vegas Valley to remove their decorative grass by the end of 2026.
Since 2002, per capita water use in Las Vegas has dropped by an impressive 58%.
Solutions and strategies for the future
Most of the cities we studied incorporated a variety of approaches to building water security and drought-proofing their community – from publishing real-time dashboards showing water use and availability in Cape Town to investing in desalination in Melbourne.
But we found the most important changes came from community members committing to and supporting efforts to conserve water and invest in water security, such as reducing lawn watering.

There are also longer-term actions that can help drought-proof a community, such as fixing or replacing water- and energy-intensive fixtures and structures. This includes upgrading home appliances, such as showers, dishwashers and toilets, to be more water efficient and investing in native and drought-tolerant landscaping.
Prioritizing green infrastructure, such as retention ponds and bioswales, that help absorb rain when it does fall and investing in water recycling can also diversify water supplies.
Taking these steps now, ahead of the next drought, can prepare cities and lessen the pain.

Food Truths
The Truth About the “Chemical” in McDonald’s Burger Buns: Should Consumers Be Concerned?
What’s in the Burger Buns:The “yoga mat chemical” controversy changed how consumers view food additives. Here’s what azodicarbonamide is, why McDonald’s removed it, and what the science actually says.
For years, headlines and social media posts have warned consumers about a so-called “yoga mat chemical” found in hamburger buns served by major fast-food chains. The claims sparked widespread concern, prompted petitions, and eventually led several restaurant companies—including McDonald’s—to change their recipes.
But what was the chemical, and is there actually a health risk today?
What Was the Controversial Ingredient?
The ingredient at the center of the controversy was azodicarbonamide (ADA), a chemical used as a dough conditioner. It helped improve the texture of bread, making dough easier to handle and producing softer, more consistent buns.
Ironically, the same compound is also used in manufacturing certain foamed plastics, including some yoga mats and shoe soles. That connection gave rise to the viral nickname, “the yoga mat chemical.”
While the comparison was technically accurate, it also lacked important context. Food-grade azodicarbonamide and industrial applications are very different, and many chemicals have multiple uses across industries.
Why Did People Become Concerned?
The concern wasn’t simply that ADA was used in food. Scientists focused on what happens during baking.
When bread is baked, most azodicarbonamide breaks down into other compounds. Some laboratory studies involving animals raised questions about one of these breakdown products, called semicarbazide (SEM), when administered in high doses.
Those findings prompted some countries to take a more cautious regulatory approach.
Why Is It Banned in Some Countries?
The European Union and Canada do not permit azodicarbonamide as a flour treatment agent. Their food safety policies often follow the precautionary principle, removing ingredients when safer alternatives exist or when scientific uncertainty remains.
In contrast, the U.S. Food and Drug Administration has determined that azodicarbonamide is safe when used within approved limits.
These differing regulations don’t necessarily mean one side believes the ingredient is dangerous while the other believes it is harmless. Instead, they reflect different philosophies about regulating food additives.
Does McDonald’s Still Use It?
No.
McDonald’s removed azodicarbonamide from its U.S. hamburger buns in 2014 following growing consumer demand for simpler ingredient lists.
Today’s buns no longer contain the ingredient, joining a broader trend among food manufacturers to eliminate additives that have become controversial with consumers.
Are There Other Ingredients Consumers Should Know About?
Modern commercial bread still contains ingredients designed to improve freshness, texture, and shelf life.
These may include:
- Calcium propionate to prevent mold
- Ascorbic acid (Vitamin C) as a dough conditioner
- Enzymes that improve consistency
- Emulsifiers that help maintain softness
These ingredients have been evaluated by food safety agencies and are generally recognized as safe when used according to regulations.
The Bigger Health Picture
Nutrition experts generally agree that focusing on one ingredient can distract from the larger issue.
The greatest health risks associated with fast food are more closely linked to:
- High sodium intake
- Excess saturated fat
- Added sugars
- Large portion sizes
- Frequent consumption of ultra-processed foods
An occasional fast-food meal is unlikely to determine someone’s long-term health. Overall dietary patterns, physical activity, sleep, and other lifestyle factors have a much greater impact.
Consumer Awareness Is Changing the Food Industry
Whether or not an ingredient poses a measurable health risk, public concern can influence corporate decisions.
Over the past decade, many food companies have reformulated products to remove controversial ingredients, reduce artificial additives, and simplify ingredient labels. In many cases, those changes have been driven as much by consumer preferences as by regulatory requirements.
The Bottom Line
The “yoga mat chemical” story captured public attention because it combined science, food safety, and memorable marketing. While azodicarbonamide was once used in some hamburger buns, including those supplied to McDonald’s, the company removed it from its U.S. buns years ago.
Current evidence suggests consumers are better served by paying attention to their overall diet rather than worrying about a single ingredient that has already disappeared from many products.
Being an informed consumer means looking beyond the headlines, understanding the science, and recognizing that nutrition is about the complete picture—not just one ingredient.

Millions of Eggs Recalled Over Possible Salmonella Risk: What Consumers Need to Know
A major egg recall is affecting nearly 1.6 million dozen eggs sold under several popular brands. Here’s how to determine if your eggs are included and what steps to take if they are.
News You Can Use This Moment!
Consumers are being urged to check their refrigerators after a major recall involving nearly 1.6 million dozen shell eggs due to the potential presence of Salmonella Enteritidis, a bacterium that can cause serious foodborne illness.
The voluntary recall, announced by Midwest Poultry Services, L.P., affects white shell eggs and brown cage-free eggs produced at two Texas farms and distributed between June 6 and July 3, 2026. According to the U.S. Food and Drug Administration (FDA), the eggs were sold through grocery stores and foodservice distributors in Texas, Louisiana, Oklahoma, Arkansas, Mississippi, and New Mexico.
What Brands Are Included?
The recalled eggs were sold under several familiar brand names, including:
- Kroger
- Simple Truth
- Brookshire’s
- Country Morning
- Sunups
Not every carton under these brands is affected. Consumers should look for:
- Plant Code: P-1950 or 0840962
- Julian Dates: 157 through 184
- Best By/Sell By Dates: July 20, 2026, through August 17, 2026
Why the Recall Matters
Salmonella can cause symptoms including:
- Diarrhea
- Fever
- Stomach cramps
- Nausea
- Vomiting
Symptoms typically begin 12 to 72 hours after eating contaminated food and usually last four to seven days. While many healthy adults recover without treatment, infections can become severe in young children, older adults, pregnant women, and people with weakened immune systems.
The FDA and the Centers for Disease Control and Prevention (CDC) are investigating a multistate outbreak involving 98 confirmed illnesses across 17 states, resulting in 26 hospitalizations. No deaths have been reported. Investigators say the recalled eggs are linked to part of the outbreak, although they do not account for every reported illness.
What Should You Do?
If you have eggs matching the recalled codes:
- Do not eat them.
- Return them to the store for a refund or dispose of them safely.
- Wash your hands thoroughly after handling the carton.
- Clean and sanitize any refrigerator shelves, containers, or kitchen surfaces the eggs may have touched.
If you have already eaten the eggs and develop symptoms of Salmonella infection, contact your healthcare provider, especially if symptoms are severe or persist.
Are Arizona Consumers Affected?
The recalled products were officially distributed in six states, and Arizona is not listed among the primary distribution states. However, because food products can move through wholesalers, travelers, or secondary retailers, Arizona consumers who recently purchased eggs while traveling—or who received eggs from family or friends in affected states—should still check the carton codes.
The Bottom Line
Food recalls are an important part of protecting public health. Taking a few moments to inspect the eggs in your refrigerator could help prevent a serious illness. If your carton matches the recalled plant codes and date range, don’t take the risk—return it or throw it away.
STM Daily News will continue to monitor this developing story and provide updates as additional information becomes available.
