This article discusses an effort to improve water quality in the village of Romeoville, Illinois, by using ion exchange (IX) softening to reduce existing levels of radium in the drinking water to comply with requirements mandated by the US Environmental Protection Agency (USEPA). The article discusses the ion exchange process for hardness and radium removal, how the necessary equipment was supplied and integrated with the existing on‐site booster pumps, wells, and reservoirs which involved writing the process control code for the ion removal system PLC with a mapping of specific data to specific locations by fiber‐optic communication using ModBus protocol. The new IX system was also integrated into Romeoville's wireless supervisory control and data acquisition (SCADA) system, which monitors and controls water and wastewater pump and control infrastructure within the village, and subsequently allows water operators to control and monitor the new IX system from distant locations via secured cellular communications and Internet technology.
