America’s Water Systems Are Failing in Climate Disasters — Here’s What’s Really Happening

🔥 America’s Water Systems Are Failing in Climate Disasters — Here’s What’s Really Happening

When wildfires hit Los Angeles earlier this year, thousands of families fled their homes — but the danger didn’t end when the flames died down. For many who returned, the real threat was hiding underground: their tap water may no longer be safe to drink.

After the fires, several neighborhoods received boil-water advisories or were told not to use the water at all. In Santa Monica, bold red warnings were taped to doors: “Do not drink the tap water.” Why? When extreme heat melts plastic pipes or drops water pressure, smoke, ash, and even toxic chemicals can seep into the system. It can take weeks or even months to flush everything out and make the water safe again.

This kind of disruption isn’t rare anymore. From the 2018 Camp Fire in Paradise, California to the 2023 Lahaina fire in Hawai’i, wildfire-related water contamination has become a recurring crisis. And it’s not just fires. Hurricanes, heat waves, floods, and droughts are now testing the limits of the U.S. water system in ways it simply wasn’t built for.

💧 When Disaster Strikes, Water Can Disappear

After Winter Storm Uri slammed Texas in 2021, millions were left without clean water as treatment plants failed and pipes burst across the state. In Puerto Rico, Hurricane Maria (2017) knocked out power and water for weeks in some communities. And in Colorado, the 2021 Marshall Fire melted service lines and led to long-term contamination concerns.

These kinds of breakdowns are happening more frequently. But according to experts, the U.S. still doesn’t have a strong system in place to manage them.

🚨 Who Decides What Counts as a “Water Emergency”?

The Safe Drinking Water Act gives the EPA authority to set standards for clean water. But when it comes to emergencies, the rules are vague and inconsistent. There’s no national law that defines when a “water emergency” begins or what kind of warning must be sent out. That means states and local governments are left to figure it out themselves—and not all of them are ready.

“Disasters expose just how patchy our system really is,” says Dr. Andrew Whelton, a water safety expert at Purdue University. He’s worked with dozens of communities recovering from wildfire damage in California, Colorado, and Hawai’i.

After the Lahaina fire, Whelton found that many residents used contaminated water before receiving official warnings, simply because no one told them soon enough.

🧪 What Can Get Into the Water?

It depends on the disaster.

• Wildfires can melt plastic pipes and let in ash, smoke, benzene (a cancer-causing chemical), and other toxins from burned homes and cars.
• Floods can overflow sewers, mixing wastewater with drinking water.
• Heat and drought can crack pipes and allow contaminants to seep in over time.
• Storms often cause power outages, which reduce water pressure. That creates suction that pulls dirty water into clean pipes — a major contamination risk.

And once these chemicals or bacteria get into the system, every home hooked up to it can be affected.

🧑‍🤝‍🧑 When the System Breaks, Volunteers Step In

In 2023, when Lahaina’s water system was contaminated, residents had to rely on bottled water deliveries. The same thing happened in Texas in 2021 — and in countless smaller towns across the U.S. since.

In places where local governments can’t respond quickly, community groups and volunteers often step up. One well-known example is BeLoved Asheville, a grassroots organization in North Carolina that has helped distribute water, food, and hygiene supplies during extreme weather events. Their work shows how important local action can be when official plans fall short.

🛠️ How Some Cities Are Fighting Back

Some towns are taking action to prevent the next crisis. After the Camp Fire, the city of Paradise, CA, began installing backflow prevention devices — special valves that stop dirty water from flowing backward into clean pipes.

In Louisville, Colorado, officials started installing automatic shutoff systems so workers won’t have to risk their lives turning off valves during future fires. Many cities are also investing in backup generators to keep water systems running when the power goes out.

🧭 What Needs to Change

Experts like Elin Betanzo, founder of Safe Water Engineering, say it’s not just about better plumbing — it’s about rethinking how we prepare for climate change.

“If we’re not building for what’s already happening,” she says, “we’re going to keep falling behind.” That means:

• Creating national standards for disaster water safety
• Giving local utilities the resources and training they need
• Rethinking development plans in high-risk areas
• And making sure the public is informed early and clearly when water becomes unsafe

Because in a world where fires burn hotter, storms hit harder, and droughts last longer, we can’t afford to treat clean water as guaranteed anymore.
