A shocking incident occurred in Florida this week when an intruder hacked into the water treatment system of Oldsmar, raising sodium hydroxide (lye) levels to dangerously high concentrations. The attack was discovered just in time, and the situation was quickly reversed before any contaminated water reached the public. The breach took place on February 5, 2021, when an unauthorized person accessed the control system via TeamViewer and increased the lye level from 100 ppm to over 11,000 ppm—far above safe limits. Fortunately, an operator noticed the unusual activity and corrected it before the tainted water could reach residents. This incident highlights a growing concern: cyberattacks on critical infrastructure are becoming more frequent and sophisticated. In Israel, similar attacks have been reported, with suspected involvement from state actors. These events are not isolated; they represent a troubling trend that should raise awareness among all citizens. So, what can you do to protect yourself? While there's no real warning for such attacks, being prepared is essential. Stockpiling potable water, having backup filtration systems, and knowing how to treat water during emergencies can make a huge difference. Many people rely on countertop filters like the Big Berkey or reverse osmosis systems. However, based on information from manufacturers, these systems may not be effective against high concentrations of lye. Lye is highly caustic and can cause severe chemical burns, blindness, and even death if ingested. If you're concerned about your own preparedness, consider adding a bug-out bag with portable water filters or purification tablets. It’s also wise to stay informed by following local news, as such incidents may not always get national coverage.
