When it comes to protecting our homes, we usually look up at the roof or out at the yard. But lately, the biggest threats are brewing right beneath our feet. Sudden craters are swallowing driveways, and invisible chemicals are turning up in the tap water. The ground itself is reminding us who's really in charge.
When the earth opens up
Nicolas Cage is currently living in hotels after a massive sinkhole swallowed his coastal driveway. The collapse caused a gas leak and cut off safe access to the property. Soil instability doesn't care about your zip code. The situation forced officials to red-tag dozens of neighboring houses, according to NBC News, because emergency vehicles simply couldn't reach them anymore.
Lighting up forever chemicals
Forever chemicals (known as PFAS) are notoriously hard to filter and even harder to track in local water supplies. These molecules wash off everyday items like nonstick cookware and stain-resistant fabrics, eventually contaminating the groundwater we rely on.
Scientists just developed fluorescent nanosensors that allow for rapid, one-step detection of these chemicals. The Department of Energy (.gov) announced that these tiny particles mix directly into water samples. If forever chemicals are present, the water literally lights up under ultraviolet light. This means local water treatment facilities can spot contamination immediately instead of waiting weeks for a lab report.
What's happening in your state
California: The Malibu crater displaced Cage and left him missing his usual Halloween trick-or-treaters. The fallout also hit an additional 24 homes that lost safe vehicular access.
Pennsylvania: A major highway in King of Prussia finally reopened after a two-year battle with recurring sinkholes. According to Inquirer.com, repair crews had to burrow down more than 100 feet to apply grout to the ancient limestone bedrock below.
What this means for you
- Keep water directed away from your house. Poor drainage is a leading cause of soil collapse. You can spot the early warning signs of shifting dirt in our foundation and structure guide.
- Pay attention to local municipal water reports. With faster testing technology rolling out, your local utility will soon have much better data on what's flowing into your home. You can decode those reports using our environmental hazards overview.
- If you live on the West Coast, the transition from dry spells to heavy rain is prime time for ground movement. Review your California seasonal checklist to make sure your retaining walls and drainage systems are clear before winter storms hit.
