A wakeup call for cybersecurity in the water sector came mere weeks into the Biden administration, in February 2021, when a hacker infiltrated a Florida water treatment facility and tried to increase the amount of sodium hydroxide to a potentially dangerous level, according to local authorities.
That greater public attention on the issue has brought improvements; the Water Information Sharing and Analysis Center , an industry hub for cyber threat data and best practices, says its membership now includes facilities that provide water to most of the US. But the sprawling US water sector, which includes more than 148,000 public water systems, has sometimes struggled with funding and personnel to protect systems.
