This article reports on a situation at the Burr Oak Regional Water District (BORWD), located in Glouster, Ohio, where trihalomethane (TTHM) levels exceeded the U.S. Environmental Protection Agency (USEPA) maximum contaminant level (MCL). Although TTHM levels in water leaving the district's plant were within the USEPA standard, these levels increased within the customers’ distribution systems. The article describes the treatment process at BORWD prior to the water being distributed to the satellite systems, along with maintaining adequate chlorine residual throughout the distribution systems, and detention time. Several treatment options were considered, with a magnetic ion exchange (MIEX) process being selected by BORWD as a more cost‐effective treatment option for reducing levels of disinfection byproduct (DBP) precursors. The MIEX treatment process is discussed, along with bringing the TTHM levels in the distribution systems into compliance as a result of using the process. Fast‐track installation of the MIEX system is described, along with immediate downstream benefits.
