There are approximately 160k small community drinking water treatment systems in the US today. These are controlled and monitored by RTU's that offer ability over GPRS, setup and control of flow valves and chemical additives like chlorine and fluoride among other treatments. These are used daily to make sure drinking water is safe. Companies like Hach and Siemens water technologies have to make these RTU's compatible and they use the Linux network stack and SSH. In Feb/23 WHO made a statement about the use of reverse osmosis water filters suggesting they are unsafe due to ability to filter out important minerals. If want to know a good target for this hack then consider US EPA drinking water.
