Johnston County, N.C. — The Johnston County Water Treatment Plant will temporarily stop feeding ammonia with chlorine for disinfection on Monday, and instead, start feeding chlorine only for Johnston County residents on the Johnston West water distribution system. The chlorine-only water can be toxic to tropical fish. Most residents will not notice a difference in their water, but some may detect a chlorine odor and might observe a slight color change, officials said. http://www.wral.com/johnston-county-to-temporarily-treat-water-with-chlorine-only/13421543/
