Nobody knows when it will happen. It could be a hack. An attack. EMP or Sleeper cells that are already in our country.
The first hours look the same.
The power goes out.
Then everything that needs power starts to fail. Your phone. Your Wi-Fi. Your fridge. And the water from your tap.
Most people never think about water. But water systems run on electricity. Pumps move it. Plants clean it. When the power fails, pressure can drop and cleaning can stop.
That is why the April warning named water and wastewater systems as targets. Walder lists wastewater among the systems she calls "so vulnerable."
And it has already happened once.
On July 26 and 27, a coordinated cyberattack hit about 30 to 36 water systems across Minnesota. In Braham, malware shut down the controls at the water plant, and the water tower could not be filled for over an hour. Other cities switched to manual control. Residents could still drink the water.
According to a preliminary New York Times report, U.S. investigators believe Iranian hackers were probably behind it. President Trump has played that down.
Robert Pape, a University of Chicago professor who studies war, called it a "brushback pitch." In baseball, that is a pitch thrown close to scare the batter, not to hit him.
His point is simple. Water and power systems now run on software, and software can be hacked. If the water is not cleaned properly, he warns, bacteria gets in, and the old, young kids and babies are the most likely to get sick.
This time, nobody lost their drinking water. It was a warning.
You can see how fast it goes wrong. In 2021, more than 4.5 million people in Texas lost power in a winter storm. Walder lives there:
