A city in Central Texas supplies drinking water to ~85,000 residents and nearby industries from the local river and is treated at the nearby water treatment plant. U.S. surface water plants follow USEPA’s SWTR, requiring 3-log removal of Giardia lamblia and 4-log for viruses. Chlorine is widely used for its virus-killing power, but concerns over regulated byproducts (THMs, HAAs), rising costs, and safety risks are pushing providers to explore chemical-free alternatives.
