OLDSMAR â The city of Oldsmar became world renowned for all the wrong reasons after the North Pinellas communityâs water treatment plant suffered a software breach over Super Bowl weekend. The Feb. 5 hack, which investigators said involved an unknown party accessing the facilityâs computer system and altering the chemical composition of the water supply, received international attention and shined a spotlight on the shortcomings of a critical component of the nationâs infrastructure system. Officials said the breach attempted to raise the level of sodium hydroxide, commonly known as lye, in the water supply to dangerous levels. It was spotted by a plant worker, who notified a supervisor who subsequently called the Pinellas County Sheriffâs Office, leading some to praise the alert employee.
